Title: Lead frame for resin sealed type semiconductor device
Inventor: NISHIKAWA HIDEYUKI
IPC: H01L23/50
Filed: 1990-01-12
Abstract: PURPOSE:To prevent resin from being left unremoved on a lead frame outer frame and to protect the lead frame outer frame against deformation when a gate resin is removed by a method wherein a part of a lead frame outer frame which comes into contact with a gate section at resin sealing is cut off.

Filed: 1978-01-20
Abstract: PURPOSE: To form powder raw material filled layers in a capsule by using centrifugal force due to rotation of the capsule prior to sintering of a composite product composed of a plurality of layers in the circumferential direction by hot hydrostatic pressing.  
     CONSTITUTION: Capsule 1 is mounted on rotary stand 4 in pit 6 and rotated at high speed together with stand 4. Metal powder for forming the outermost layer is first charged into capsule 1 from supply inlet 8 of cover 7 loosely covered on capsule 1. The powder forms a layer on the inner wall of capsule 1 by means of centrifugal force. At this time, movable partition plate 3 is brought into contact with the inside of the metal powder layer to prevent disorder of the layer boundary. Next, plate 3 is moved to the central side of capsule 1, and the second layer is similarly formed inside the outermost layer. Thus, 2W5 composite layers are formed while using centrifugal force and moving plate 3. The capsule is then degassed, hermetically sealed, and subjected to hot hydrostatic pressing to obtain a composite sintered material.

IPC: F04B49/10
Filed: 1979-01-20
Abstract: PURPOSE: To prevent abnormal temperature rise in a casing and extend the life of a compressor and a motor by constructing to control the compressor corresponding to the wind pressure of a ventilator and stop the motor of the compressor when the wind pressure of the ventilator has dropped abnormally.  
     CONSTITUTION: When power is switched on, a ventilator 6 starts. If the ventilator 6 is normal at this time, a switch mechanism 7 operates and a relay R 1  is excited, and by this action, a normally open contact point r 1  closes. At the same time, an electromagnetic switch A is excited and its normally open contact point a 1  closes, and then a motor 2b is started and a compressor 2a starts. If the ventilator 6 becomes abnormal and the wind pressure drops, the relay R 1  is demagnetized and the normally open contact point r 1  opens and correspondingly, the electromagnetic switch A is demagnetized and the motor 2b is stopped. By so doing, abnormal temperature rise in a casing is prevented and the life of the compressor 2a and the motor 2b can be extended.
