    • A proposed computer input device for transmitting the displacement data representing the quantity and direction of the movement of a cursor to a computer is operable in a narrow space and easily portable. The input device is provided with a pressure sensitive pad composed of a conductive layer formed on the underside of a flexible sheet and a resistor layer formed on the upper face of a substrate at a predetermined interval from the conductive layer. When the flexible sheet is depressed, the conductive layer contacts the resistor layer at the depressed position. In a control circuit connected to the conductive layer and the resistor layer, when the contact of the conductive layer with the resistor layer is detected, a voltage of 5V is applied alternately in a horizontal direction and a vertical direction on the surface of the resistor layer. The depressed position on the pressure sensitive pad is sequentially computed from the voltage value produced on the conductive layer when the voltage is applied. Based on the computation result, the movement count number is calculated and transmitted to the computer.

    • A pressure control device for a hydraulic braking system of an automotive vehicle is provided with a master cylinder for pressurizing hydraulic fluid according to a braking action of a driver. A wheel cylinder for applying braking force to a wheel is communicated with the master cylinder through a main passage. An accumulator is connected to the main passage. A rotating condition of the wheel is detected by a detector and is outputted as a signal indicative of the rotating condition of the wheel. A hydraulic pressure controller is arranged to control the wheel cylinder hydraulic pressure when the detector detects one of a lock condition and a slippage condition. The hydraulic pressure controller is communicated with the main passage. A switching device is arranged to stop the communication between the master cylinder and the hydraulic pressure controller, and open the communication between the accumulator and the hydraulic pressure controller when the detector detects the slippage condition in acceleration. Therefore, during the slippage control in acceleration, the hydraulic fluid stored in the hydraulic pressure controller is returned to the main passage owing to the pressure difference therebetween.
