Title: Method for disintegrating sand core
Inventor: OIKAWA KEIICHI
IPC: B22D29/00
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To promote the disintegration of a hollow sand core in the inner part of a cast product and to disintegrate a sand core in a short time by inserting metallic pieces into the hollow part of the sand core, vibrating the metallic pieces in the hollow part of the sand core and disintegrating the sand core. SOLUTION: The metallic pieces 6 inserted into the hollow part 3 of the sand core 2 is vibrated by resonating the vibration of the cast product 1 generated by hitting a feeder head part 4 of the cast product 1 with a hitting device 5. The metallic pieces 6 inserted into the hollow part 3 of the sand core 2 is resonated to the vibration of the cast product 1 at the time of hitting the feeder head part 4 of the cast product 1 and mutually collided and scattered in the hollow part 3 and collided to the sand core 2, and the sand core 2 is perfectly disintegrated. Since the feeder head 4 is hit, additional hitting part is unnecessary. Further, since the cast product is not directly hit, but the metallic pieces 6 are vibrated by hitting through the feeder head 4, the development of the crack in the cast product 1 is prevented.

Filed: 1980-07-17
Abstract: PURPOSE:To reduce the surge absorbing circuit loss and the capacity of a discharging resistor by connecting a filter capacitor in parallel with an inverter circuit and providing a circuit for clamping the charging voltage to the surge absorbing condenser. CONSTITUTION:When a gate turn-off thyristor 6a is turned off, a current i1 flowing through the thyristor is rapidly reduced, and a current i2 will flow through a diode 9a and a capacitor 10a. Thus, the capacitor 10a is charged at the shown polarity, and when it reaches the power voltage, the diode 7b is conducted and the current i3 will flow, and a current i4 will accordingly flow through a clamping diode 14 to clamp the voltage of the capacitor 10a. Thus, the capacitor is not charged higher than the voltages of the filter capacitor 3R(3S, 3T) connected in parallel with the respective inverter circuit 4R(4S, 4T). Accordingly the capacity of the surge absorbing capacitor 10a is not necessarily raised higher than the filter capacitors, and the charging energy can be reduced. Accordingly, the discharging loss of the discharging resistor 11a can be reduced.
