Abstract: A vehicle power transmission device includes a forward first clutch between an engine and an input shaft of a continuously variable transmission, and a second clutch between an output shaft of the continuously variable transmission and driving wheels. When the hydraulic fluid of the hydraulic pump is not supplied to the first disconnection device and the second disconnection device, a dragging torque generated in the second disconnection device is larger than a dragging torque generated in the first disconnection device.

Abstract: A component-shared information management method for managing information shared by a plurality of components constituting application software, is characterized in that a shared information management means receives a registration request from a processing executing component among the plurality of components, receives a specific type of information from the component and manages the information thus obtained as shared information. By adopting this method, application software in computer systems can be developed more efficiently.

Abstract: An engine and a motor are connected to the drive wheels of a vehicle via an automatic transmission. The drive wheels are driven using one of or both of the motor and the engine depending on the running state. The automatic transmission varies the drive ratio by the discharge pressure of the oil pressure pump. The oil pressure pump is driven by a second motor. When the automatic transmission is varying the drive ratio, the discharge of the oil pressure pump is increased by increasing the rotational speed of the second motor and thus the required oil for varying the drive ratio is maintained.

Abstract: An antilock brake system which decreases a braking pressure to prevent drive wheels from locking is applied to a hybrid vehicle wherein an engine and a motor are connected to the drive wheels via a continuously variable transmission. The rotation torque of a motor is applied to the drive wheels when the braking pressure is reduced due to antilock control so that the engine braking force which acts during braking does not interfere with antilock control.

Abstract: A continuously variable transmission of an automotive vehicle comprises a primary pulley disposed on a power input shaft, and a secondary pulley disposed on a power output shaft. Each of the primary and secondary pulleys includes a fixed wheel counterpart having a first sheave surface, and a movable wheel counterpart having a second sheave surface. The first and second sheave surfaces face each other to form a pulley groove whose width is changeable with axial movement of the movable wheel counterpart. An endless belt is wound on the primary pulley and the secondary pulley so that the secondary pulley is drivably connected to the primary pulley. The belt includes a steel belt portion, and a plurality of steel elements supported on the steel belt portion and aligned along the steel belt portion. The respective steel elements are engageable in the pulley grooves of the primary pulley and the secondary pulley.

Abstract: A motor/generator and drive wheel are connected to an engine, and the drive wheel is driven by the engine and motor/generator according to running conditions. A sensor which detects a slip of the drive wheel and a sensor which detects a depression of an accelerator pedal are provided, and the motor/generator is operated as a generator when the accelerator pedal is depressed and the drive wheel has slipped. Further, a spin of the drive wheel is prevented by increasing the rotation resistance of the motor/generator according to the frictional coefficient of the road surface.

Abstract: An engine and generator/motor are connected to the input shaft of a continuously variable transmission, and the output shaft of the continuously variable transmission is connected to drive wheels. A target value of a coasting torque acting on the output shaft during coasting is set according to a vehicle speed. A real coasting torque is estimated from the output torque of the engine and frictional torque of the continuously variable transmission. By making the generator/motor function as a generator or a motor, fluctuation of the engine braking force due to a variation of drive ratio during coasting is suppressed so that the real coasting torque coincides with the target value.

Abstract: An apparatus for automatic inspection of printed circuit board assemblies inspects for the correct presence, positioning, and orientation of component parts mounted on a base printed circuit board by processing an image which is obtained from the base printed circuit board mounted with these component parts. In this method for inputting reference printed circuit board assembly data to such an apparatus, a reference base printed circuit board is prepared with reference component parts mounted on it in which the visual distinction between the reference base printed circuit board and these reference component parts is clear, and then an image is obtained from this reference base printed circuit board assembly, and this image is then processed in order to obtain the reference printed circuit board assembly data. Thereby laborious keying in of such reference printed circuit board assembly data is avoided, and the occurrence of errors is minimized.
