Title: Pressure casting method
Inventor: ITOU TAKEJI
IPC: B22D17/22
Filed: 1980-12-10
Abstract: PURPOSE: To cast products of high quality free from cavity defects by reducing the gases existing in product cavities as far as possible by devicing the operation of pressurizing pins in a pressure casting method using said pins.  
     CONSTITUTION: A prescribed amt. of molten metal is teemed into the space delineated by a counter plunger 7 and a sleeve 4 through a pouring port 8 with a ladle 12, and is kept still to allow impurities to float upward. Next, the plunger 7 is lowered and a gate 11 is opened to introduce the molten metal 13 gently into product cavities 3. When the molten metal 13 is introduced under pressure up to the positions B, that is, near the leading ends of the pressurizing pins 10 projected into the cavities 3, the pins 10 are pulled up synchronously with the filling speed of the molten metal 13. Prior to the solidification of the molten metal 13 after filling of the molten metal 13, the pins 10 are again projected to pressurize the molten metal 13. By this pressurizing, slight small cavities 14 are annihilated approximately throughly.

IPC: G04G3/00
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a correcting circuit having an error-correcting range enlarged by improving reliability of its correcting operation. SOLUTION: A first signal Sac having same as a period of an AC power source Vac is counted by a first counting means 3d to measure a unit time. Correct or error of a counting operation of the means 3d is decided based on a counted value of a second counting means 3c for counting a second signal Su having shorter period than that of the signal Sac. In the case of deciding the error, the counting operation is reexecuted. Each time the means 3d measures a unit time, a third counting means 3e conducts a counting operation. A correcting unit time is measured by an arrival of its counted value at a unit correction counted value corresponding to the correcting unit time. A command for correcting the counting operation is given to a timepiece LSI based on the correcting unit time.
