Title: Device for controlling wheel rotation
Inventor: SASAJIMA YOSHIO
IPC: B60T8/66
Filed: 1987-10-09
Abstract: PURPOSE:To detect wheel planing with high reliability by computing a logical product of a comparative output obtained on the basis of comparison between wheel rotation detecting signals and ground relative speed detecting signals of a vehicle and a monitor output from a monitor section monitoring a speed detector, and taking said logical product output signal as a wheel rotation control signal. CONSTITUTION:When the brake is applied to wheels 2 with a brake pedal stepped on, the wheel rotation detecting signal V is lowered in decreasing revolution depending on braking force, the planing of the wheels 2 occurs concurrently. This situation allows an reduction in vehicle speeds to be maintained moderately much more than an reduction in wheel revolutions, there causes thereby the difference between the wheel rotation detecting signal V1 and the speed detecting signal V2, the aforesaid difference is enlarged as the wheels 2 come close to a locking condition wherein planing is increased. Accordingly, observing the aforesaid difference from the stand point of a comparison circuit 8 enables wheel locking to be predicted or detected. On the other hand, the operating condition of a speed detector 6 is monitored by a monitor section 7 at all time in such a way that its output and the output from the comparison circuit 8 are inputted into a logical circuit 9 for letting a signal A having taken up the aforesaid logical product, be taken as a wheel planing detecting signal.

Filed: 1989-09-30
Abstract: PURPOSE:To prevent the generation of uneven density in an output image by boosting the pressure value of pressure development in response to the rise in the carrying speed of a light- and pressure-sensitive recording material after the final stage of a series of exposure process is completed. CONSTITUTION:When a lamp driving circuit 11 lights a lamp 10 to continue lighting for a prescribed length of time, a pressuring motor driver 8 rotates and drives a pressure motor 7 at the timing t12 to start pressure development under a pressure value P1. When the pressure development starts, the carrying speed is S1 as it is, and the lamp 10 is put off at the timing t13 to terminate exposure. At the timing t13, the carrying speed S1 is accelerated to S2, and simultaneously the pressure value P1 is boosted to P2. The carrying speed S2 is continued until copying ends at the timing t15. The instant that the carrying speed is accelerated, the pressure value is boosted; therefore, pressure per unit length of the roll-like recording medium is never weakened.

IPC: G09G3/20
Filed: 1985-11-15
Abstract: PURPOSE:To prevent the destruction of a light emitting diode by designating a position where no light emitting diode exists in an abnormal mode. CONSTITUTION:When a pulse oscillator or a CPU 10 has the abnormality, the row control signals Sl1-Slp and column control signals Sr1-Srg are supplied to both decoders 20 and 30 via capacities Cl2 and Cr2.
