Title: Die casting device
Inventor: HASHIMOTO MASAOKI
IPC: B22C9/06
Filed: 1981-05-01
Abstract: PURPOSE: To prevent the formation of gaseous holes and solidification shrinkage cavities by providing means of charging molten metal into mold cavities under pressure, and flowing the molten metal after expelling the gas from the inside of the cavities first.  
     CONSTITUTION: When molten metal is charged into mold cavities 3 under pressure, the gas in the cavities 3 flows through a vent well 4 and a vent runner 8 into the 2nd chamber part 11 of a cylinder chamber 5 and is released to the outside of a movable die 2 through a gas discharge passage 9. When the molten metal is forced upward into the 1st chamber part 10 through the well 4, a piston valve body 12 is driven to the left valve closing position to shut off the communication between the passage 9 and the runner 8 and the molten metal in the cavities 3 is cast in a prescribed pressurizing state. Upon solidification of the molten metal in the cavities 3, the die 2 is moved leftward and the casting is parted. The transfer of the dies is accomplished surely by this.

Title: Protection unit for control unit using micro computer
Inventor: TAKAHASHI OSAMU
IPC: G06F1/24
Filed: 1978-06-07
Abstract: PURPOSE: To prevent important dangers such as damage from being caused by the abnormal operation of controlled elements, by performing surely an initial reset at a power source restoration time after the breaking of a commercial power source dependent upon instantaneous power failure.  
     CONSTITUTION: When commercial power source 1 is broken, transistor 11 is opened, and output voltage A of DC power source 4 starts lowering gradually. Meanwhile, capacitor 16 is not discharged, and the voltage value rises, and consequently, transistor 20 is closed. As a result, the charge charged in capacitor 5 with a polarity shown in the figure is discharged. Next, when power source 1 is restored, the charge of capacitor 16 is discharged through transistor 11, and transistor 20 is opened. Consequently, a high voltage approximately equal to the output voltage of DC power source 4 is applied to the initial reset terminal of micro computer 7 at a restoration time of power source 1, thus making it possible to reset to program counter to the initial state.
