Title: Dashpot device of engine for vehicle
Inventor: TOMITA KAZUO
IPC: F02D9/02
Filed: 1981-11-05
Abstract: PURPOSE:To effectively actuate a dashpot device only when a brake is not applied, in the dashpot device in which moving speed of a throttle valve to its full closing positon is liminted, by decreasing a degree of throttling if application of the brake is sensed. CONSTITUTION:Depression of an accelerator pedal is released, when a brake is not applied, a brake switch 20 is opened to deexcite a solenoid coil 18, and a valve element 16 closes an atmospheric port 17, then air in a diaphragm chamber 6 is discharged via a throttle passage 14 in a negative pressure delay valve 13, thus rapid movement of a throttle valve to its full closing position is avoided, in consequence, a deceleration shock can be prevented. On the contrary, if a brake pedal is depressed, the switch 20 is closed to excite the solenoid coil 18 and open the atmospheric port 17, then the throttle valve 2 is returned to its full closing position substantially without application of dashpot action. In this way, deterioration of fuel consumption and/or deceleration performance can be avoided.

Title: Divider circuit for galois field
Inventor: INOUE TOORU
IPC: G06F7/72
Filed: 1981-11-06
Abstract: PURPOSE:To make scale of a divider circuit small to have a proper scale and at the same time to decrease the arithmetic time, by using two divider circuits consisting of shift registers which are exactly equal to each other, giving the same frequency of divisions to both the divisor and the dividend with the same original root alpha and defining the numerator as the answer of division when the denominator is equal to alpha deg.. CONSTITUTION:For the divider circuits 22 and 22b, the contents of a shift register which is a primary component element are multiplied by alpha<-1> every time the shift pulse is supplied. A alpha deg. pattern detecting circuit 23 detects whether the contents of the shift register constituting the circuit 22b is set at alpha deg. or not. A control circuit 24 controls the circuits 22, 22b and 23 respectively. The clock pulse of the circuit 24 is stopped when the circuit 23 detects alpha deg., i.e., 1. Thus an arithmetic result c=b/a is delivered to an output terminal 21.
