Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of an AC generator for the lower fuel consumption of a vehicle by forming a regulator for controlling the generated current of the AC generator to be a fixed value, and a power transmission mechanism which is fitted between an engine and the shaft of the AC generator and has a speed changing means. SOLUTION: An AC generator 1 is connected to an engine 2 through a pulley 31a disposed on the shaft of the AC generator 1, a pulley 31b disposed on the shaft 2 of the engine 2 and a belt 32. The pulley 31a and the pulley 31b are connected to a hydraulic pipe 33 connected to a hydraulic pump 34. Each of the pulley 31a and the pulley 31b has a mechanism whose pulley ratio changes depending upon hydraulic pressure, and the diameter of the pulley onto which the belt is applied changes depending upon the magnitude of hydraulic pressure, thereby conducting a speed change. The change in the pulley ratio permits the revolutions of a rotating shaft of the AC generator to be restrained so as to be low, thus it is possible to achieve low fuel consumption with high efficiency and operation under low noise.

IPC: H01L29/812
Filed: 1987-10-31
Abstract: PURPOSE:To prevent direct contact between a gate electrode and a semi- insulation substrate by forming an insulation film on the surface of a semiconductor substrate of an area other than an operation layer and high-concentration impurities layer and by constituting so that a gate electrode can be extended on this insulation film at an area other than the operation layer. CONSTITUTION:An operation layer 4 is formed on a semi-insulation substrate and a high-concentration impurities layer 5 is formed, sandwiching it. But, an insulation film 7 such as silicon nitride is formed on the surface of a semi- insulation substrate 6 of an area other than this operation layer 4 and the high-concentration impurities layer 5. A gate electrode 1 is extended onto the insulation film 7 in an area other than the operation layer 5. Since an area other than the operation layer 4 is coated with the insulation film 7 consisting of silicon nitride film, the gate electrode 1 does not come into contact with the semi-insulation substrate 6 and no concentration of electric field occurs in this area, thus enabling side gate effect to be restricted.

IPC: F16H57/01
Filed: 1991-10-23
Abstract: PURPOSE: To prevent heat-related damage to the torque transmitting devices of a transmission by limiting the number of shifts. CONSTITUTION: An improved method for scheduling of a gear ratio shifting in the transmission 14 of a vehicle 10 adaptively adjusts a normal shift schedule to avoid shift-related overheating of the torque transmitting devices 28-34 of the transmission 14. In normal operation, the shift of the transmission 14 is scheduled by comparing the measurements of vehicle speed and engine throttle position 16 with predefined load data. In the background, a transmission controller 270 determines cumulative thermal energy stored in the torque transmitting devices. If excessive energy is indicated the normal shift schedule is modified to allow extended operation in the lower speed ratios. When the cumulative energy indication returns to a normal value, normal shift scheduling is resumed.
