Title: Cooler-heater
Inventor: KITA TAKAHIRO
IPC: F24F11/02
Filed: 1978-05-12
Abstract: PURPOSE: To operate a refrigeration cycle normally by delaying the starting of a heat exchange blower from the starting of a compressor until a temperature sensor of a heat exchange reaches a predetermined temperature in cooling operating, and forcedly starting the blower when the sensor does not reach a predetermined temperature at a predetermined time in heating operation.  
     CONSTITUTION: When a compressor 1 is operated in cooling operation, a thermistor 10 detects the lowering of the temperature of a refrigerant pipe 7a. A control circuits 15 does not make a relay 15 until the thermistor 10 reaches a predetermined temperature, so that the starting of a room-side heat exchange blower 9 is delayed from the starting of the compressor 1. In heating operation, when room temperature is low and the temperature of the pipe 7a does not rise to a predetermined temperature at a predetermined time set on a timer 16, the blower 9 is operated forcedl. Blow-off of stinking hot wind and cold wind is prevented in both cooling and heating operations, and a refrigeration cycle system is operated normally without disadvantages.

IPC: G11C11/418
Filed: 1992-02-07
Abstract: PURPOSE:To facilitate the layout of column switches and to reduce an arrangement area by connecting the column switches composed of PMOSs between bit lines and data lines and providing prescribed latch circuits between bit line pairs. CONSTITUTION:The column switches CS1-CS2<n+1> are connected between bit lines and data lines and the switches are constituted of only PMOSs transistors.

Title: Pressure control equipment
Inventor: TADA KEIJI
IPC: F16K31/53
Filed: 1985-03-25
Abstract: PURPOSE:To make pressure change smooth by means of the function of a driving system to produce a pressure control equipment being easy to control the pressure by providing a power transmitting means comprising at least a pair of elliptical members between an exhaust valve and its driving system. CONSTITUTION:A throttle valve 6 located inside a vacuum exhaust system 3 is mounted on a valve rotating shaft 11, and its rotation is controlled by a power transmitting means comprising the valve rotating shaft 11, elliptic gears 9, 10, and a motor driving shaft 8, and a motor 7 working as a driving system. The 90 deg. rotation of the throttle valve 6 round the valve rotating shaft 11 changes its opening area over a range from full opening to total closing. Since the power transmitting means is composed of the elliptic gears 9, 10, the rotational angle of the valve rotating shaft 11 to the rotational angle of the motor driving shaft 8 changes in the mode in which the rotational angle of the valve rotating shift 11 is small at first and increases gradually though the motor rotates at a fixed speed. Even when the motor is kept at the fixed rotation, the throttle valve moves slowly near its totally closed position where the pressure changes sharply, and moves quickly near its fully opened position where the pressure changes slightly. Consequently, the rate of pressure fluctuation becomes approximately constant, and the pressure can be therefore easily controlled.
