摘要： A power transmission arrangement for a vehicle adapted to transmit a drive power from an engine to a transmission via a wet multi-plate clutch. An electronic controller automatically disengages and engages the clutch normally, but does not engage the clutch if a transmission gear position other than a predetermined one is selected for starting of a vehicle. This prevents clutch engagement with an excessively high gear position. Otherwise, the clutch would overslip and be deteriorated soon. A torque converter may further be provided in tandem to the clutch so that the engine power is transmitted to the transmission through the clutch and torque converter.

摘要： A clutch connection/disconnection system which causes a friction clutch to slip appropriately when the clutch is automatically disconnected and connected. An engine is controlled according an accelerate command signal. During automatic clutch connection, the accelerate command signal approaches an actual accelerator pedal position signal. An approaching speed of the accelerate command signal is stepwise changed based on comparison between a particular value and a threshold value. The "particular value" is a differential value of a difference between an engine rotational speed and clutch rotational speed. When the clutch is slipping, the engine rotational speed is controlled to rise gently so that overslipping of the clutch is prevented.

摘要： A surface acoustic wave device includes a piezoelectric substrate, an interdigital electrode pattern, and a resistor thin film. The piezoelectric substrate has a piezoelectric effect. The interdigital electrode pattern is made of a conductive thin film and formed on the piezoelectric substrate to perform conversion between an electrical signal and a surface acoustic wave. The resistor thin film is formed on the piezoelectric substrate to electrically connect the piezoelectric substrate to the interdigital electrode pattern. The resistor thin film serves to remove charges from a surface of the piezoelectric substrate due to a pyroelectric effect to the interdigital electrode pattern.

摘要： A zoom lens system is composed of two lens units. The first lens unit is arranged at an object-side end and the second lens unit is arranged at an image-side end. The first lens unit has one lens element of a positive refractive power. The second lens unit has two lens elements. One is an aspherical plastic lens of non-refractive power. The other is a lens having a negative refractive power. During zooming from a wide angle end to a telephoto end, the distance between the first and second lens units is decreased.
