Patent JP-H0353712-A (JP)
Title: Input buffer circuit
Inventor: NAGASHIMA HIROKAZU
IPC: H03K17/687
Filed: 1989-07-21
Abstract: PURPOSE:To expand the range of an operationable power voltage by decreasing a resistance toward a reference level from an output terminal when a power voltage is high and decreasing the resistance toward the power voltage side from the output terminal when the power voltage is low so as to vary the logic decision level. CONSTITUTION:A P-channel transistor(TR) 8 and N-channel TRs Q1-Qn form a constant voltage supply circuit, and P-channel TRs 9, 10 and an N-channel TR 11 form a voltage detection circuit. While a Vcc is higher than an optional voltage, the relation of Va=VCC exists, and since a P-channel TR 5 controlling the parallel state of a CMOS inverter is turned off and an N-channel TR 6 is turned on, the resistance at the conduction toward the reference level from an output 16 of the CMOS inverter is decreased and the logical decision level is lowered. On the other hand, while the VCC is lower than an optional voltage, since the Va reaches the reference level, the P-channel TR 5 is turned on and the N-channel TR 6 is turned off, and the resistance at conduction toward the power voltage side from the output 16 is decreased and the logic decision level is increased.

Title: Slip control device of car
Inventor: SUZUKI NOBUHIKO
IPC: B60T8/66
Filed: 1991-07-30
Abstract: PURPOSE:To reduce burden applied on a brake pad and lessen change in the car behavior when the control has ended. CONSTITUTION:A microcomputer 24 senses the car body speed VB from the speeds VRL VRR of rear wheels 7, 8, produces the reference speed value from the body speed, and determines deviations of the speeds VFL, VFR of front wheels 3, 4 from this reference value. When the deviation goes out of the allowable range, the microcomputer controls hydraulic control valves 12, 14, etc., so that the speeds VFL, VFR of the front wheels 3, 4 approach the reference value, and controls the braking forces for the front wheels 3, 4 in accordance with the speed deviation. Also the microcomputer 24 corrects the reference speed in accordance with the burden on a brake pad and makes restitution to the reference speed with which no gradual correction with time is applied to the corrected reference speed value when the braking force control for the front wheels 3, 4 has ended.
