    摘要: A lock-up control system for an automatic transmission including a torque converter having an input member and an output member, a multiple stage gear transmission gear mechanism connected with the output member of the torque converter and having a plurality of gear stages and a lock-up clutch for connecting the input member and the output member bypassing the torque converter wherein an engaging force in the lock-up clutch is controllable so as to change the amount of torque transmitted through the lock-up clutch. The system comprises shift detecting device for detecting a shift operation in the transmission mechanism and control device for controlling the engaging force of the torque converter to be maintained at a predetermined value smaller than a fully engaged condition of the lock-up clutch and larger than an entirely released condition of the lock-up clutch when the shift operation is detected by the shift detecting device.

    摘要: In an automatic transmission, a hydraulic pressure control valve produces hydraulic pressure according to a pilot pressure fed thereto. A duty solenoid valve controls the pilot pressure. An oil temperature sensor detects the temperature of the hydraulic oil and a driving period changing circuit changes the driving period of the duty solenoid valve according to the temperature of the hydraulic oil so that the driving period is long when the temperature of the hydraulic oil is low and short when the temperature of the hydraulic oil is high.

    摘要: A resin compound for molding precision parts containing 20 to 40% by weight of at least one of polyphenylene sulfide and aromatic polyester thermotropic liquid crystalline polymer, 15 to 25% by weight of whisker and 40 to 60% by weight of spherical fine particles, wherein the total content of the whisker and the spherical fine particles is 60 to 80% by weight, and a resin compound for molding precision parts containing 20 to 40% by weight of at least one of polyphenylene sulfide and aromatic polyester thermotropic liquid crystalline polymer, 5 to 25% by weight of whisker, 40 to 75% by weight of spherical fine particles and 0.5 to 3% by weight of silane coupling agent, wherein the total content of the whisker and the spherical fine particles is 60 to 80% by weight are disclosed. Mechanical strength of the resin compounds can be increased without the impairment of dimensional precision, surface smoothness and low coefficient of thermal expansion. The resin compounds can be suitably used for molding precision parts, for instance, sleeve, ferrule and the like.
