Title: Transistor switch
Inventor: OOBA HIDEO
IPC: H03K17/04
Filed: 1981-03-17
Abstract: PURPOSE:To enhance the switching speed, by appling a switch driving signal to the primary side of a transformer and connecting a series circuit consisting of the secondary winding and a capacitor between the base and the emitter of a transistor and connecting a series circuit consisting of the tertiary winding and a resistance to the emitter and one end of the secondary winding. CONSTITUTION:When a switch S is closed, a voltage is induced in a secondary winding n2 to charge a capacitor C, and the base current is flowed to a transistor TR by a voltage induced in a tertiary winding to turn on the TR. At this time, since the charging current of the capacitor C becomes the base current also, the speed of this turning-on is high. When the switch S is opened, the capacitor C is discharged, and a voltage is induced in the tertiary winding by this discharging current, and a backward base current is supplied to the TR. Consequently, the speed of turning-off of the TR is high.

Abstract: PURPOSE:To reduce the difference of thickness of a sheet and prevent the inflation of the sheet which is due to the stagnation of air by a method wherein the surface of a core member is smoothed and adhesive agent is applied on the surface of the core member except recessed parts having vacuum holes while an air non-permeable soft sheet provided with a tension force is mounted thereon by vacuum bonding. CONSTITUTION:A non-bonding area 6 is provided in an area between both projected corners C, C of a flat core member 3 and bonding areas 5, coated with adhesive agent 2, are provided on both side surfaces while an air non-permeable soft sheet 1 is abutted against the surface of the core member 3 to bond and fix it under a condition that a tensile elastic force F exists in the sheet 1. In the non-bonding area 6, the sheet 1 is adhered to the core member 3 by the tension force F only and air between both layers is discharged through vacuum holes, therefore, expanded air becomes flowing air (a) and is discharged through the holes 4 even when the remaining air between the core member 3 and the non-permeable soft sheet 1 is expanded by heating effected by sunshine heat or the like. On the other hand, the core member 3 has slipping effect on the corner C of the core member 3 by the tension force F of the sheet 1, therefore, the difference of the thickness of the sheet 1, which is generated in the sheet 1, can be reduced.
