Title: Power circuit
Inventor: YAEGAWA KAZUHIRO
IPC: H02J1/00
Filed: 1988-01-21
Abstract: PURPOSE:To expand the operating voltage margin of an LSI at the time when a consumed current is reduced by stepping down a supply voltage by impressing the output of a step-down circuit or the supply voltage to an internal circuit after switching them according to the output of the detection circuit of a voltage level. CONSTITUTION:The voltage of a prescribed level is supplied to an internal logic circuit 1 in a state that the supply voltage VDD is high, and on the other hand, when the level of the supply voltage VDD falls, it is detected, and the voltage of prescribed level is substituted for the supply voltage VDD, and is supplied to the internal logic circuit 1. Accordingly, even when the voltage of the prescribed level can not be generated as the output of the voltage step- down circuit 6 because of the fall of the supply voltage VDD, the supply voltage VDD of the level higher than the prescribed level can be supplied to the internal logic circuit 1 as substituting it for the voltage of the prescribed level. Thus, in the LSI using the power circuit provided with the step-down circuit 6, the lower limit margin of the operating voltage can be expanded, and the life of the battery used for power supply can be extended.

Title: Oxygen displacement die casting method
Inventor: HIRASAWA HIROAKI
IPC: B22D17/14
Filed: 1984-01-25
Abstract: PURPOSE:To improve an oxygen displacement rate and to reduce oxygen consumption by supplying oxygen to the inside of the cavity while a pouring port is closed by a plunger after pouring of a molten metal is completed and ejecting the molten metal upon completion of the oxygen displacement. CONSTITUTION:Dies 1, 2 are clamped and a plunger tip 10 is put in a retreat position. A molten steel is poured through a pouring port 8 into a sleeve 3. The chip 10 is moved to the position between and oxygen supply port 7 and the port 8 and while the chip is once stopped, gaseous oxygen is supplied from the port 7 through the sleeve 3, a runner 6 and a sprue 5 into a cavity 4. The air in the cavity 4 is forcibly removed through a vent passage 11 in this stage. When the oxygen displacement in the cavity 4 is completed, the passage 11 is closed to stop the oxygen supply and thereafter a plunger 9 is driven to inject the molten metal. The oxygen displacement rate in the cavity is thus improved and the oxygen consumption is reduced.

Abstract: PURPOSE:To prevent the generation of shrinkage cavities and deformation by scooping out the molten metal of the part corresponding to a thick wall part gradually at the same instant when solidification begins from the part in contact with the molten metal poured into a mold. CONSTITUTION:Molten metal 2 of a low m. p. metal, for example, zinc alloy, is poured into an open type mold 15. The molten metal 2 begins to solidify from the parts in contact with the mold 15 with lapse of time, but the part 17 near the center of a thick-walled part 6 still maintains a fully molten state. Thereupon, at the same instant when the solidification of the metal 2 begins, the metal 2 in the neighborhood 17 at the center of the part 6 is scooped out gradually with a suitable means. Then, the solidification progresses at a uniform rate from the part of the mold 15 in contact with the mold plane 16 thereof. At the point of the time when the wall thickness at which no shrinkage and cavities are generated in the solidified parts, the scooping up of the remaining metal 2 is ceased, and when the casting cools thoroughly, it is removed from the mold 15.
