Title: Semiconductor device
Inventor: SUZUKI KOUJI
IPC: H01L23/34
Filed: 1978-10-20
Abstract: PURPOSE: To prevent the cracks of a semiconductor element and the disconnection of conductors, by fixing the semiconductor element to a base of a concave portion mounted to a radiator plate, and by sealing the whole with resin.  
     CONSTITUTION: A square cylinder-like concave portion 12 is manufactured to a radiator plate 11 in copper, a semiconductor element 15 that conductors 14 are connected to a Si element piece 13 is fixed to the base with a lead-tin alloy and the whole is sealed with resin 16. The conductors 14 are connected to lead frames 17 inserted and put into the resin 16. According to this constitution, stress to the flanks of the element piece 13 is remarkably moderated because only the components of the little stress of the resin 16 of a small zone partitioned by the concave portion apply to the flanks of the element piece 13 and the flanks of the concave portion 12. When impact force is applied from the outside, the impact force is also lightened at the flanks of the element piece 13 considerably. Thus, the cracks of the semiconductor element are prevented, and the conductors are not disconnected because the uniform, thermal, expansive force of the resin applies to the conductors.

Title: Control system for power supply of information processor
Inventor: MAGOORI EIJI
IPC: G06F1/26
Filed: 1986-06-05
Abstract: PURPOSE:To avoid the erasion of information or the mechanical breakage of a memory medium even in case an operator cuts off the power supply inadvertently, by invalidating the cut-off instruction for power supply of an information processor as long as an electrical or mechanical system is working. CONSTITUTION:A logical action control circuit 1 produces a logical action mode display signal 11 in a communication mode and a data processing mode, i.e., in an action mode of an electrical system and under communication with a mechanical action control circuit 2. The circuit 2 instructs the action of the circuit 2 and produces a mechanical action mode display signal 11. While the circuit 2 instructs the action of a mechanical system and produces a mechanical action mode display signal 12. Then a power supply cut-off instructing circuit 3 produces a power supply cut-off instruction signal 13 for information processor according to the instruction of an operator and delivers it to a power supply cut-off instruction valid/ invalid deciding circuit 4. Receiving the signal 13, the circuit 4 delivers a power supply cut-off permission signal 14 to a power supply circuit 5 as long as both signals 11 and 12 are kept under an action mode display state. Thus the signal 13 is invalidated even though the operator cuts off inadvertently the power supply in an action mode of the electrical or mechanical system. Thus the circuit 5 is never actuated to avoid the erasion of information or the mechanical breakage of a memory medium.
