Title: Method for driving thyristor
Inventor: OGURA TSUNEO
IPC: H01L29/749
Filed: 1987-02-26
Abstract: PURPOSE:To increase the turn-on capacity by a method wherein both of a MOS gate (the first gate electrode) or a MOS thyristor and the second gate electrode in direct contact with the second base layer are used to turn on a MOS transistor. CONSTITUTION:The second gate electrode 8 is impressed with a gate voltage VG2 to be 5-10V of positive bias to a cathode at a time t1. Then, electrons are injected from the second emitter layer 4 to the second base layer 3 starting to run to the first layer 2. Next, when the first gate electrode 6 is impressed with around 5-10V of positive bias at another time t2, an MOS transistor is turned on to inject the electrons of the second emitter layer 4 into the first base layer 2 through the intermediary of a channel region 10 of MOS transistor. Due to such an electron current, a hole is injected from the first emitter layer 1 to the first base layer 2 reaching the turn on period at the other time t3 to bring about the turn on state at the time t4. Later, the thyristor can sustain the turn on state even if the gate voltages VG1, VG2 are restored to zero volt.

Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To easily perform seal-packaging which is difficult to break and easy to unseal by forming a heat-sealing lid welding portion having a plurality of recesses on an opening of a container body. SOLUTION: A heat-sealing lid welding portion 11 is integrally formed by folding outward like a flange on an opening of a container body 10 made of a synthetic resin. A plurality of recesses 12 are formed on an upper surface of the welding portion 11. In addition, half cuts 13 are cut on the upper surface between the plurality of recesses 12 of the portion 11. In this constitution, if the opening of the container 10 is heat-sealed by a heat-sealing lid 20 under such conditions that sufficient sealing strength can be given, no breakage due to external pressure may occur. On the other hand, pulling a non-welded protrusion 21 of the lid upward causes the welding portion 11 to be torn in a ring shape on a line formed by the half cuts 13 and the recesses 12. At this time, presence of the recesses 12 which are non-sealed parts permits peeling with less force.
