Title: Pulse heat bonding method
Inventor: KONNO YOSHITO
IPC: H01L21/60
Filed: 1991-06-05
Abstract: PURPOSE:To embody a pulse heat bonding method which is free of contaminating on a bonding tool as for a pulse heat bonding method. CONSTITUTION:A plurality of lead wires 12 connected with a semiconductor chip 1 are positioned and laminated on a plurality of electrode patterns 14 installed to a device board 13. They are depressed by means of a bonding tool 10 while electric power is supplied to the bonding tool 10 at the same time so as to heat up and melt the metal plated on the lead wires 12 and the electrode patterns 14 and thereby carries out bonding, which constitutes a pulse heat bonding method. After the lead wires 12 and the plating metal on the electrode patterns 14 are molten, the supply of power to the bonding tool 10 is halted. At the same time, the application of pressure is reduced so that the lead wires 12 may be held at such force that does not produce any deformation of the lead wires even if the bonding tool 10 is subjected to shrinkage. After melting metal is thoroughly cured, the bonding tool 10 is removed from the bonding section.

Title: Foamed resin gear and manufacture of thereof
Inventor: TAKAHASHI KAZUNAGA
IPC: B29C67/00
Filed: 1981-08-28
Abstract: PURPOSE:To obtain a gear of a foamable resin wherein the surface layer part has a densely packed unfoamed structure, while the inner layer part has a coarsely packed foamed structure, with them monolithically molded, thereby the clicks will be absorbed and will not be transmitted. CONSTITUTION:After an appropriate amount of a foamable resin 14 is injected through a gate 11 into a cavity 10 defined by molds 8, 9, a high pressure gas 15 is forced into the cavity 10. Therefore the foaming action of foamable resin 14 is restricted by the high pressure gas 15, so that the resin adjacent to the walls of the cavity 10 is solidified relatively quickly to form the highly densified surface layer part 6. When a surface layer part 7 having a prescribed thickness is formed, the introduction of the high pressure gas 15 is stopped to make the cavity be at normal pressure, so that the unsolidified foamable resin 14 is rapidly foamed to form the coarsely packed inner layer part 7.

Abstract: PURPOSE:To make a transistor not to be started again when oscillation of a circuit is once stopped in case of a discharge lump coming in its abnormal state, etc., by providing a timer circuit which outputs a signal for turning on a switch provided with a control terminal after the specific time passes after a power supply is made so as to prevent a starting current from flowing into the transistor. CONSTITUTION:A timer circuit 26 is so set that a capacitor 22 is charged with electric load through a resistor 20 after a power supply is made and electric current flows into the base of a transistor 25 through a constant voltage diode 23 after the specific time passes. A starting circuit 36 is short-circuited by the transistor 25 after the timer circuit 26 is put in operation so that any starting current does not flow into a transistor 11. Because the middle point of the starting circuit 36 composed of resistors connected to each other in series is short-circuited to the emitter of the transistor 11 after the specific period passes by means of the transistor 25, the starting circuit can be put in its off state without starting the transistor 11 when oscillation is stopped except in normal lighting state. Therefore, the transistor 11 can be safely protected.
