Title: Control method of continuously variable transmission for vehicle
Inventor: IYODA HISAO
IPC: B60W10/10
Filed: 1987-02-12
Abstract: PURPOSE:To improve the operational property, by correcting the gear shift ratio responding to the thermal correction coefficient, in the engine cooling condition when the engine operation condition varies largely depending on the required output amount of the engine. CONSTITUTION:In case when the engine water temperature detected by a water temperature sensor 65b is about 70 deg.C or more, or when the throttle opening detected by a throttle sensor 64 is about 50% or more, the transmission control is carried out taking the standard object rotation frequency as it is as the object rotation frequency. On the other hand, when the water temperature of the engine 10 is lower (lower than 70 deg.C), the standard object rotation frequency is corrected by the temperature correction coefficient which is corrected by the throttle opening correction coefficient, and the transmission control is carried out depending on the resulting object rotation frequency.

Title: Circuit board
Inventor: TSUKAMOTO SOTARO
IPC: H05K1/18
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To provide a circuit board which can prevent a coupling due to overlap of first and second patterns, without thickening or widening an insulation layer. SOLUTION: A second layer pattern P2 is formed beneath a first layer pattern P1 on a first insulation layer Z1 for forming a hybrid IC, so that patterns do not overlap on the front and back, as much as possible. The pattern P1 is an aggregate of electric components mounting lands with numerous blank parts and pattern P2 run through beneath electric components (blank parts of the pattern P1) to other blank parts, hence has high degrees of freedom for the runabout without overlapping. Owing to little overlap of these patterns P1, P2, coupling is prevented to reduce the size of a hybrid IC, without thickening the insulation layer Z1.

Title: Lifting device for load receiving platform
Inventor: TORIMOTO HIDEO
IPC: B60P1/44
Filed: 1980-03-10
Abstract: PURPOSE: To achieve a smooth and safe loading and unloading for trucks by making the lord receiving platform flush with the loading platform at the upper lift limit while it is inclined backward at the lower lift limit in such a manner that a space between pivots at the end of a pair of arms provided at the rear of a body is made larger than that between pivots at the base end thereof.  
     CONSTITUTION: While a load receiving platform 6 is flush with a loading platform 2, a hydraulic cylinder 10 is reduced to lower the load receiving platform 6. The top of the load receiving platform 6 is inclined backward with a trapezaided link mechanism 8 and lowers down to the lowest position. This eliminates difference from the ground to smooth the loading to a truck, whose retraction is regulated with a stopper 13. With the stretching of the hydraulic cylinder 10, the support 7 is raised gradually by the action of the trapezaided link mechanism 8 until it becomes so vertical that the load receiving platform 6 become flush with the loading platform 2. Then, the cylinder stops. This enables a smooth and safe loading and unloading for trucks or the like.

Title: Reset control circuit for channel switching device
Inventor: SUZUKI NOBORU
IPC: G06F13/14
Filed: 1990-02-14
Abstract: PURPOSE:To miniaturize the reset control circuit to incorporate it in a device circuit by outputting a detection signal from a comparing circuit to output various control signals from a relay circuit at the time when the rise voltage of a time constant circuit reaches a prescribed value. CONSTITUTION:When a power source is turned on, a capacitor C is charged through a resistance R1. When the potential of the positive electrode of the capacitor, namely, the negative input of an operational amplifier OP reaches a prescribed voltage RV, the amplifier OP outputs the signal indicting that the rise voltage of a main power source MV reaches the prescribed voltage RV. A transistor Q energizes a relay circuit 19 in accordance with the output of the operational amplifier OP, and each contact output RS of the circuit 19 goes to a state corresponding to energization. When the main power source MV is turned off, the potential of the positive electrode of the capacitor C, namely, the negative input of the amplifier OP is reduced, and the amplifier OP detects turning-off of the power source by the fall to the voltage RV or lower to output the detection output. The transistor Q is turned off in accordance with the output of the amplifier OP to disenergize the circuit. Thus, the state of the output RS is switched.
