Patent JP-H06351108-A (JP)
Title: Charger
Inventor: IIDA TAKAHIDE
IPC: B60L11/18
Filed: 1993-06-02
Abstract: PURPOSE:To eliminate a damage to a switching element and a circuit element near the switching element even if noise is introduced by providing a relay switch for electrically opening a rectifier and the two switching elements when a signal from a driving circuit to the switching element is OFF. CONSTITUTION:A DC relay 13 is connected to a circuit disposed at a rear stage of an electrolytic capacitor 6 to apply a voltage of the capacitor 6 to a series circuit of IGBTs 7, 8 through the relay 13. As a result, a manual switch 10 is opened by a user in a state that an AC from a commercial power source 1 remains supplied to stop supply of a DC to the relay 12 at a moment when an operation of a driving circuit 9 is stopped, and its contact is immediately opened. Accordingly, even if spikelike noise is introduced from the power source 1 at the time of stopping the circuit 9, the noise is effectively cut OFF by the relay 13 in which its contact is opened. Thus, malfunctions of the IGBTs 7, 8 can be effectively prevented.

IPC: B22D7/06
Filed: 1993-06-03
Abstract: PURPOSE:To enable the fitting of a hanger to a steel ingot, to prevent the surface oxidation and to produce the steel ingot having high quality by floating up a fire-resistant board arranging the metallic hanger on the molten steel surface in a mold. CONSTITUTION:Casting is executed while floating up the board 1 arranging the hanger 2 on the molten steel surface. At the time of solidifying the molten steel, as the hanger 2 at the lower part of the board 1 is inserted into the steel ingot, the steel ingot with hanger is produced. As the fire-resistant board 1 is smaller in specific gravity than the molten steel 5, this board is floated up on the molten steel surface during casting and risen up. After casting the necessary wt., the molten steel 5 is solidified and at this time, as a part of the hanger 2 at the lower part of the board is inserted as cast is, the hanger is integrated with the steel ingot after solidifying. By this method, the hanger 2 can easily be fitted to the steel ingot and as the board 1 is floated up, the preventing effect of the surface oxidation during casting is enhanced and the steel ingot having high quality can be produced.

Filed: 1994-06-15
Abstract: PURPOSE:To keep and control accuracy and quality and to enhance productivity by constructing a circuit from the integral molding of a high-voltage wire, a conductive terminal, a base and the like. CONSTITUTION:A slope covering the upper opening of a casing 1 and open upwards to both sides, and a conductive plastic terminal 7 supporting a high- voltage wire 5 are covered with an insulating plastic base 9 that holds the terminal 7, and the wire 5 is attached to the lower surface of the base 9 by the terminal 7. The terminal 7 has a plurality of metallic sleeves 6 embedded in the top surface of the base 9 at intervals. Discharge needles 3 are embedded in the terminal 7 via the sleeves 6 and have their ends oriented toward the surface of the base 9. The wire 5 has an insulating cover, and the terminal 7 is molded integrally with the wire 5, so a high voltage applied to the conductor of the wire 5 is induced to the terminal 7, passed through the sleeve 6, and instantly causes a discharge at each discharge needle 3. The need for molding the metallic sleeve from an insulating material in close contact with the metallic terminal or assembling the circuit by insertion of the high-voltage wire into the metallic sleeve is therefore eliminated.
