IPC: B29C45/06
Filed: 1984-01-31
Abstract: PURPOSE:To miniaturize the installation space of a molding device and consequently improve the work efficiency by a method wherein the respective positions for injection, pressure test, deflashing and taking out are provided on a rotary supporting plate so as to be able to simultaneously operate said positions in a series of works. CONSTITUTION:At an injection position A, resin is injected between an engraved space 21 and a core 14 in order to mold a hollow molded piece M. At a pressure test position B following the position A, pressurized air is blown through an air hole in the core 14 so as to push down and open a check valve in order to check the pressure resistance of the molded piece M with said pressurized air. Next, the molded piece M is shifted to a cutting-off work position C in order to cut off flashes 43 and 43' by the cutters of cutting-off devices 40 and 40' respectively. Finally, the piece M is shifted to a taking-out position so as to lead compressed air to the air hole 23 in order to separate the molded piece M from the core 14 and to fall the piece M downwards.

Title: Semiconductor storage device
Inventor: TANAKA HIROAKI
IPC: G11C11/403
Filed: 1994-02-10
Abstract: PURPOSE:To reduce the operation current and to reduce the power consumption at the time of self refresh operation mode by using a voltage lower than a source voltage at the time of the operation except the mode concerned. CONSTITUTION:At the time of self-refresh operation mode, when a control signal SELF becomes a high level, a control circuit 4 output becomes a low level, and an FETP 4 becomes conductive. Then, a resistor R1 is short-circuited, and a comparison voltage Va becomes higher than that at the time when no resistor R1 is short-circuited since the voltage Va is obtained by dividing the voltage between an output terminal and a low level power source Vss between the resistors R2, R3, and a step-down source voltage becomes lower. Thus, since the step-down source voltage is set lower at the time of self-refresh operation mode compared with the case of an operation mode except that mode, the operation currents of a step-down source voltage system stand-by current consumption circuit 5 and a self-refresh operation current consumption circuit 6 are reduced, and the current consumption of the whole device is reduced, and the current consumption is reduced without lowering an access speed.

Title: Ignition device for engine
Inventor: MATSUYAMA YOUJI
IPC: F02P9/00
Filed: 1983-02-05
Abstract: PURPOSE:To prevent re-start of an engine in the event that a kill switch remains in an unreturned position after temporary stop of the engine, by providing a relay designed to be turned on by a kill switch and to be turned off by an on- operation of a starter switch and thereby controlling current feed to an ignition unit. CONSTITUTION:When a kill switch 7 is turned on, a first transistor (a) is turned on and is held under on condition by a switching operation of a relay switch 6b to its contact point B. Thus, a relay 6 self-holds stoppage of current feed to an ignition unit. When a starter switch 4 is turned on and the first transistor (a) is turned on, the self-hold of the relay 6 is released to switch the relay switch 6b to its contact point A, thereby permitting current feed to the ignition unit 5. In this manner, even when the kill switch remains in an unreturned position, it is possible to start an engine.
