Abstract: PURPOSE:To restrain the temperature of exhaust gas from rising, in an engine provided with a supercharger and an intercooler, by compensating the supply amount of fuel in accordance with the temperature of intake-air so that the supply amount of fuel is increased when the temperature of intake-air is relatively high, to control such that the air-fuel ratio of the engine becomes rich. CONSTITUTION:Upon operation of an engine, in a control circuit 50, a basic fuel injection amount tauP is at first computed in accordance with outputs from an airflow sensor 35 and a rotational speed sensor 32. Then an intake-air temperature I downstream of the airflow sensor 35, and an intake-air temperature II downstream of an intercooler 20 which are detected, respectively by intake-air temperature sensors 33, 34, are read by the control circuit 50. In accordance with the intake-air temperature I , a compensating coefficient (f) which increases gradually in a temperature range of the intake- air I lower than 20 deg.. C but decreases in a temperature range of the intake-air I higher than 20 deg.. C, is computed. Further, in accordance with the intake-air temperature IIanother compensating coefficient F which has variation rates different from each other between two ranges of 60-120 deg.. C and higher than 120 deg.C C, is computed. Then, the basic fuel injection time is compensated in accordance with the compensating coefficients (f), F and the other compensating coefficients.

IPC: F16D69/02
Filed: 1983-12-27
Abstract: PURPOSE:To produce stable friction member for car brake having high friction factor and excellent abrasion resistance through paper making by adding specific wt% of rubber latex into friction member. CONSTITUTION:1-30wt% of rubber latex is added into friction member produced through paper making to be employed for brake or clutch of car or motorcycle.

IPC: H02P7/29
Filed: 1992-09-18
Abstract: PURPOSE:To obtain excellent constant speed characteristics in the case of setting any speed by maintaining a hysteresis ratio in which speed setting means and hysteresis setting means are separated constant. CONSTITUTION:When load current flowing to a DC motor(DM) 2 is increased at the time of increasing a load, a voltage between a drain and a source of a FET 3 at the time of turning ON the FET 3 is increased, and counterelectromotive force is decreased due to the decrease in a speed of the DM 2. Thus, the discharging amount of a capacitor 62 is reduced, the time to reduce to a voltage Von of a formula I is increased, a period H of comparing means 7 is increased, and an ON period of the FET 3 is increased. A voltage rising ratio of the capacitor 62 is fastened due to the decrease in a counterelectromotive force of the DM 2 at the time of turning OFF the FET 3, a period L of the means 7 is shortened, and the OFF period of the FET 3 is shortened. Thus, an applied voltage to the DM 2 is increased, the decrease in the speed of the DM 2 is suppressed, and the speed is maintained constant.
