Title: Power converter
Inventor: TAKAHARA HIDEAKI
IPC: H02M7/155
Filed: 1987-04-27
Abstract: PURPOSE:To prevent the breakdown of an element by connecting a first capacitor having a small capacity between positive and negative terminals at the interconnection terminals of a converter and an inverter and connecting a second capacitor having a large capacity through an impedance element. CONSTITUTION:A power converter is composed of a transformer TR connected to a current collector PAN, a converter CONV through a reactor L1, a capacitor CO for smoothing and an inverter INV, and drives an induction motor IM as load. A capacitor C1 is connected between the positive and negative terminals of the DC output terminals of the converter CONV and a capacitor C2 between the positive and negative terminals of the DC input terminals of the inverter INV respectively while resistors R1, R2 are interposed at that time. The capacity of the capacitors C1, C2 is made smaller than the capacitor CO. Accordingly, the voltage fluctuation of pulse-shaped high frequency is inhibited by the capacitors C1, C2 having small capacity, and the voltage fluctuation of low frequency is suppressed by the capacitor CO having large capacity.

Title: Belt transmission device
Inventor: TANI KAZUYOSHI
IPC: F16H7/08
Filed: 1982-06-16
Abstract: PURPOSE:To absorb and relieve a fluctuation in tension produced corresponding to a fluctuation in the angular speed of the output shaft of an engine and to lengthen a belt life, by regulating the maximum tension into a value below a given value by means of a tension regulating means mounted to the maximum or a second tension span of a belt tension. CONSTITUTION:In case a tension regulating means 7 is installed to the maximum tension span 6A against a fluctuation in an angular speed omega of a crank shaft 2, the inertia force of a drive pulley 4 is exerted to a belt 6 by allowing the belt to follow the fuctuation in the crank shaft 2, and thus the span 6A first attampts to increase in a belt tension. An increase in the tension is regulated by the regulating means 7, and an idler pulley 8 moves against the force of an elastic body 9. This causes absorbing and relieving of the increase in the tension, resulting in suppressing said increase. Meanwhile, when the tension decreases, the belt 6 is energized by the elastic force of the elastic body 9 produced as a result of the belt restoring into the deformation of the elastic body to increase the tension, resulting in the reduction in the amplitude of fluctuation. Thus, as a result of the fluctuation in the angular speed of the crank shaft 2 being regulated by the tension regulating means 7, the fluctuation transmitted to the driven pulley 4 reduces.

Title: Anti-skid control device
Inventor: YAMADA SHINICHI
IPC: B60T8/58
Filed: 1992-04-23
Abstract: PURPOSE:To eliminate the follow-up delay of deceleration at the time of ground ing getting over the stepped road surface by suppressing the reduction of brak ing liquid pressure at the wheel lock tendency time by a control means upon judging the sudden reaction change of the road surface, and accelerating the boosting of braking liquid pressure at the wheel lock tendency released time. CONSTITUTION:The wheel speed VW and wheel acceleration dVW are compared with the reference speed VA and reference acceleration G1 so as to judge the lock tendency of a wheel. When the lock tendency is large, it is judged to be the anti-skid control timing, and the road surface state is judged to perform braking liquid pressure control judgment. When the wheel has the lock tendency, the wheel speed VW is compared with the set speed VSL. In the case of being judged to be negative, the wheel speed is reset during short-time pressure reduction, so that the wheel is judged to be shifted into the grounded state from the floating state, and pressure reduction is stopped to perform hold output, taking account of the further reset of the wheel speed at the grounding time. When the wheel speed is lower than the set speed VSL, a vehicle is judged to be in ultra-low mu road travel, and pressure reduction is outputted.
