Title: Traction Control Device

Technical Field and Background:
In the related art, there is known a traction control technology that adjusts engine output, motor output, or the like at the time of slip of drive wheels of a vehicle so as to inhibit the extent of slip of the drive wheels to predetermined value or less. One of such a traction control technology known is a technology that corrects slip by controlling output torque of an electric vehicle driving motor when slip of the drive wheels is detected (for example, PTL 1). The traction control technology of the related art inhibits previously occurring slip by adjusting output or a driving motor or the like when slip of the drive wheels is detected. Thus, initial slip at the start of the vehicle cannot be prevented. Particularly, initial slip increases when a magnetic pickup type-wheel speed sensor is employed because a low speed of the vehicle cannot be detected. For example, when the vehicle starts on a snowy uphill road, the vehicle may not start once the drive wheels slip because compacted snow decreases a road surface coefficient of friction μ. In order to prevent initial slip at the start of the vehicle, there is suggested a device that computes the road surface coefficient of friction μ from forward and backward and leftward and rightward acceleration to compute a drive torque restriction value for the start of the vehicle on the basis of the estimated road surface coefficient of friction. μ and that inhibits a rise in the output of the driving motor when drive torque is greater than or equal to the drive torque restriction value (for example, PTL 2).

Title: Gas Turbine Engine Driving Multiple Fans

Technical Field and Background:
Gas turbine engines are known, and typically include a fan delivering air into a compressor. The air is compressed in the compressor, and delivered into a combustion section where it is mixed with fuel and ignited. Products of the combustion pass downstream over turbine rotors, which in turn drive the compressor and fan. Fan rotors are becoming increasingly large in diameter. This increase presents challenges with regard to operation and packaging. Thus, it has been proposed to drive a plurality of fan rotors from a single gas turbine engine core. The enlargement of fan diameter has increased with the recent development of a gear reduction driving the fan from the turbine rotor. The fans typically drive air through both a bypass duct, and into the compressor. A bypass ratio is defined as the volume of air delivered into the bypass duct as propulsion, compared to the volume of air delivered into the compressor. The bypass ratio has become larger as the fan diameter has become larger. It has been proposed to drive a plurality of smaller fan rotors from a single core engine. Typically these proposals have only driven two fan rotors. One proposal has been to drive as many as four fan rotors from a single core engine, however, the transmission for doing so would not share the power to the fan rotors in an efficient manner.

Title: Terminal-To-Terminal Communication

Technical Field and Background:
Terminal-to-terminal communication may allow data transmissions to be made directly between two or more terminals of a telecommunication system. The terminal-to-terminal communication may overlay regular cellular communications, and may be performed with or without cellular network coverage. In some instances, using terminal-to-terminal communication may increase network capacity. For example, terminal-to-terminal communication may permit spatial multiplexing, which may allow for higher relative spectrum usage. Employing terminal-to-terminal communication may also permit throughput between terminals to be increased if a terminal-to-terminal link experiences better channel quality than a cellular link. Using terminal-to-terminal communication may reduce resource usage when data is transmitted once between two terminals during a terminal-to-terminal transmission, as compared to transmitting the same data twice between the two terminals over a cellular link, i.e., once through an uplink (UL) transmission from a transmitting terminal to a base station and once through a downlink (DL) transmission to a receiving terminal from the base station.

Title: Connector Assembly Having Self-Adjusting Male And Female Connector Elements

Technical Field and Background:
The connectors are used in various applications, for example, electrical connectors are used for connecting electrical elements used for continuous transmission of power. Generally, the connector assembly includes a male connector sub-assembly and a female connector sub-assembly. The male connector sub-assembly includes a conductive male pin contact at the front and the base portion for electrical wire termination or connection with an insulated cover body assembled over the conductive male pin contact. The female connector sub-assembly includes a conductive female sleeve contact at the front and the base portion for electrical wire termination or connection with an insulated cover body assembled on the conductive female sleeve contact. The conductive female sleeve contact of the female connector sub-assembly receives the conductive male pin contact of the male connector sub-assembly for configuring the connector assembly. The male and female connector sub-assemblies are connected to each other via engagement between the conductive male pin contact and the conductive female sleeve contact to configure the connector assembly used for continuous transmission of power in the most extreme conditions. Typical applications include use as a connector assembly for transmission of power from generator sets to switchgear or SCR (silicon-controlled rectifiers) controls, from a control house to the traction motors, mud pumps, draw works, rotary tables, cement pumps and top drives. More specifically, the electrical connector assembly is used for connecting an electrical cable to a fixed mating connector. Certain electrical connector assemblies are configured specifically to cater to the drilling rig industry. These connector assemblies are configured for applications where the connector assemblies are required to operate in the most extreme service conditions and are subjected to up to 1,000 Volts AC or DC voltage and up to 1,135 Amps of continuous power. The field assembly and the installation of many inland drilling rigs have been using single pole electrical connector assemblies that can be prepared in the field. These connector assemblies take different forms, including pin and collet type connector assemblies or plug and receptacle type connector assemblies. All of these types of connector assemblies, particularly, the plug and receptacle type connector assemblies require a desired fit between elements of a plug or a male connector sub-assembly and a receptacle or a female connector sub-assembly to ensure minimal resistance to the high current loads. However, due to the extreme service conditions to which the connector assembly is subjected to, it is difficult to maintain a desired fit between the elements of the male and female connector sub-assemblies of the connector assembly. Particularly, the connector assemblies are subjected to most extreme service conditions and have to withstand vibrations, shocks and wear and tear. Generally, the elements of the male and female connector sub-assemblies, particularly, the engaging conductive male pin contact and conductive female sleeve contact wear out and fail to maintain the necessary tight fit between the male and female connector sub-assemblies and because of improper contact between the male and female connector sub-assemblies, the connection assembly fails to efficiently transmit power there-though due to high resistance to the high current loads and there are chances of power leakage and damage to the connector assembly. To achieve the desired fit between the conductive male pin contact and the conductive female sleeve contact of the respective male and female connector assemblies of the connector assembly, the use of a self-adjustable male connector assembly has been suggested in the prior art, wherein the conductive male pin contact of the male connector assembly has a split pin configuration that facilitates in adjusting the conductive male pin's external diameter. In case of the split pin configuration of the conductive male pin contact, the conductive male pin contact is cut into two halves by a slot cut along the length of the conductive male pin contact. A Belleville washer and a fixing stud mechanism are generally used within the slot to make small adjustments in the external diameter of the conductive male pin contact. A fixing stud is driven into the conductive male pin contact that exerts a force against the Belleville washer.

Title: Control Apparatus Of Four-Wheel Drive Vehicle

Technical Field and Background:
The present invention relates to a control apparatus of a four-wheel drive vehicle which has an engine of which an operating mode is switchable between an all-cylinder operating mode and a reduced-cylinder operating mode, and to the four-wheel drive vehicle. Conventionally, four-wheel drive vehicles are known to comprise a power unit provided with a transfer case for driving rear wheels. The power unit includes an engine, a transmission, and a front-wheel differential device, is mounted on a front part of a vehicle body, and drives left and right front-wheels (main drive wheels) of the four-wheel drive vehicle. Further, a propeller shaft extending in front-and-rear directions of the vehicle body is coupled to the transfer case, and a rear-wheel differential device is coupled to a rear end part of the propeller shaft, so that left and right rear-wheels (auxiliary drive wheels) of the four-wheel drive vehicle can also be driven. In the four-wheel drive vehicle, a coupling capable of varying a transmission torque may be disposed on the propeller shaft. When the coupling is fully fastened (i.e., engaged), an output torque of the engine is evenly applied to the front and rear wheels (four-wheel drive state), when the coupling is fully released (i.e., disengaged), the output torque of the engine is only applied to the front wheels (two-wheel drive state), and when the coupling is between the fully engaged state and the fully disengaged state, the distribution of the transmission torque applied to the rear wheels is adjusted according to the engaged state. Further, as the transfer case, a pair of bevel gears meshed with each other, specifically, a bevel gear provided on an extended line of a central axis of the front-wheel differential device and a bevel gear provided on an extended line of a central axis of the propeller shaft, are used to transmit power to the propeller shaft extending in the front-and-rear directions of the vehicle body from the front-wheel differential device, of which a central axis extends in a width direction of the vehicle body. With regards to four-wheel drive vehicles, in the four-wheel drive state where the front and rear wheels are driven, the distribution of the output torque of the engine to the rear wheels is increased compared to the two-wheel drive state where only the front wheels are driven, leading to drive loss and degradation in fuel economy; therefore, four-wheel drive vehicles normally travel in the two-wheel drive state, travelling in the four-wheel drive state only when necessary. However, since the output torque of the engine varies due to intermittently performed combustion inside a combustion chamber of the engine, the variation in output torque is subsequently applied to the transfer case via the transmission and the front-wheel differential device, so that in the two-wheel drive state, a drivetrain from the bevel gear of the transfer case to the rear wheels, i.e., including the propeller shaft and the rear-wheel differential device, rotates in a non-power transmission state where power is not transmitted from the drivetrain. Therefore, depending on the oscillation frequency of the torque variation of the engine, the drivetrain having a predetermined characteristic frequency of vibration with respect to torsional vibration co-resonates with the frequency of the torque variation of the engine and causes a large vibration in the drivetrain. Due to this vibration, noise is generated by teeth rattling between the pair of bevel gears, for example, which may cause noise inside a cabin of the vehicle. FIG. 18 is a chart illustrating relationships between an oscillation frequency of torque variation of an engine and a torque transmission characteristic with respect to torsional vibration of a drivetrain, in a four-wheel drive vehicle and a two-wheel drive vehicle having conventional basic structures, respectively. A waveform W 1 of the transmission characteristic (the waveform indicated by the solid line) with respect to the torsional vibration of the four-wheel drive vehicle and a waveform W 2 of the transmission characteristic (the waveform indicated by the dashed line) with respect to the torsional vibration of the two-wheel drive vehicle, which are illustrated in FIG. 18 , both have resonance peaks P 1 and P 2 at frequencies below a practical range of the engine (below a frequency f L ).
