Title: Induction heating device
Inventor: ISOGAI MASAYUKI
IPC: H05B6/12
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To lower the generation of overheat and failures due to the deterioration of driving characteristic to be generated by the lowering of driving voltage by separately stopping drive of a drive circuit from operation of a control unit so as to stop the operation of a switching element in the case where low voltage of a switching element driving power source is detected by a voltage detecting circuit. SOLUTION: A voltage detecting circuit 11 is formed by connecting an intermediate point of a series circuit of a Zener diode 110, which is connected to a switching element driving power source, and a resistor 111 to a base of a transistor 113 through a resistor 112, and connecting a collector of the transistor 113 to a pull-up resistor 114 and a base of a transistor 115. With this structure, in the case where the switching element driving power source is lower than the Zener voltage, the transistor 113 is turned off, and the transistor 115 is turned on. As a result, since input of a drive circuit 12 is stopped independently of the pulse output condition of a control circuit 9, IGBT is not driven.

Title: Thyristor scherbius system
Inventor: MATSUMURA OSAMU
IPC: H02P23/00
Filed: 1979-02-14
Abstract: PURPOSE: To reduce the number of circuit components in a thyristor Scherbius system by opening a switch connected in parallel with a starting resistor when starting a wound-rotor type induction motor and short-circuiting the other end of the starting resistor through a forward converter.  
     CONSTITUTION: When an operation command is applied to a motor, an inverter transformer primary side AC breaker 52G and then a motor primary side AC breaker 52P are sequentially closed to accelerate the motor with a starting resistor R 2  connected in parallel with a Scherbius operation starting solenoid contactor 42. Since the reverse armature side terminal of the starting resistor R 2  is short-circuited in advance by a power rectifier SR when starting the motor, a power inverter THY is forwardly converted to apply a circulating current to the power rectifier SR. The secondary side of the motor is short-circuited through the resistor R 2  by the rectifier SR, and the motor IM is accelerated according to the torque characteristics shortened by the resistor R 2 . When the motor enters into a Scherbius operation enabling range, the resistor R 2  is short-circuited to start the Scherbius operation.

Title: Automatic coating machine
Inventor: KIRIGAKUBO MINORU
IPC: B05B12/08
Filed: 1986-01-28
Abstract: PURPOSE:To contrive perfect automation of coating work, by automatically detecting whether a coating agent is injected from a coating mechanism part in a mist form. CONSTITUTION:For example, if a set amount of an adhesive is injected from a first coating gun 91 in a mist form, the light allowed to irradiate a jet region a1 from the light emitting part 14 of a detector 131 is reflected from the mist like adhesive to be received by a light receiving part 15 and, if the quantity of received light is predetermined one, a jet state is judged to be normal. When the quantity of received light is excessive or too little, the jet quantity of the adhesive is judged to be abnormal. Unless the mist like adhesive is injected from the coating gun 91, the light irradiated toward the jet area a1 from the light emitting part 14 of the detector 131 is not almost reflected and the quantity of received light of the light receiving part 15 becomes almost zero and, therefore, an alarm buzzer is operated to automatically stop an operation part.

Abstract: PROBLEM TO BE SOLVED: To provide a vacuum degassing apparatus and a method for sealing a joining part thereof, with which the suction of air can be prevented. SOLUTION: O rings 21, 22 are doubly disposed over tube periphery in the joining positions of a flange 6a or the like, and a groove (gas flowing part) 23 is arranged between the O ring 21 at the outer peripheral side and the O ring 22 at the inner peripheral side. Inert gas from an introducing pipe 24 is introduced into the groove 23 and the gas in the groove 23 is discharged from an exhaust pipe 25. In this way, the inert gas is changed in succession to carry out the leak in outer air. Further, since the inert gas having >=10 times of the groove 23 vol., is supplied into the groove 23, the leaked-in air is sufficiently diluted, and even in the case of invading the diluted gas into molten steel, the component of nitrogen, or the like, in the molten steel is scarcely increased.

Drum 2 rotates vertically, ejects gas from hole 2b and separate pellets, which are draw onto hole 2c one by one. Each pellet is released from hole 2c by stopper 3a placed on the upper side and is put on conveyor 5 via shoot 3. Next, while pellets are in transport, their positions and outer appearances are detected (4), stored and rated. Then they are placed between belts 5 and 8 and are reversed by roller 6. Then, they are again detected (7), and the results are checked and stored. Based on these results, pellets are classified (9), and only pellets of good appearance are taken into electric  characteristic drum 10.

Title: Lead frame and resin-molded semiconductor device using same
Inventor: KAKO KINSHI
IPC: H01L23/28
Filed: 1992-01-31
Abstract: PURPOSE:To prevent generation of package cracks. CONSTITUTION:A lead frame 3A constituted of a die pad 4 and inner leads 5 and outer leads 6 which are formed in the peripheral part of the die pad 4. A thin stripe protrusion 20 is formed between the inner leads 5. The protrusion 20 is so exposed that the same surface as the side surface of a package 11 formed by sealing resin 10 is constituted, and forms a vapor pressure reducing means. Since the die pad is exposed to the outer space via the thin stripe protrusion, the pressure of water vapor which is generated by heating water content existing in the vicinity of the die pad when a resin-molded semiconductor device is packaged can be reduced. Hence generation of package crack due to vapor pressure can be prevented.
