Title: Semiconductor device
Inventor: MATSUMOTO YASUHIKO
IPC: H01L21/74
Filed: 1987-10-31
Abstract: PURPOSE:To prevent generation of defects in an epitaxial layer due to steps created by a buried layer by causing the epitaxial layer to grow while opening an oxide film within a region of the buried layer. CONSTITUTION:An arsenic buried layer 2 is formed on the surface of a silicon substrate 1. When forming an oxide film 3 on such buried layer, steps created due to biting in of the oxide film are observed around the buried layer 2 on the silicon surface. When selectively etching the oxide film 3, an aperture must be constructed so that the aperture is smaller than the buried layer 2. Then an epitaxial layer 4 is formed within such aperture. According to the constitution, the presence of the buried layer 2 prevents the steps created on the buried layer 2 when forming the oxide film 3 from protruding into the region of the epitaxial layer 4.

Title: Impact sensor
Inventor: OBUCHI SHIGEKI
IPC: H01H35/14
Filed: 1993-11-05
Abstract: PURPOSE:To improve reliability by injecting a liquid into a sensor housing, so that a closing time is lengthened of a read switch to stabilize operating a protecting fixture. CONSTITUTION:The inside of a sensor housing 1 is filled with a liquid 8 of oil or the like. When acceleration by an impact is generated, a moving member 4 advances to a side of a front stopper 6 against a spring 5. The member 4, since it is tapered to a side of the spring 5, easily advances, to enable a contact to early close of a lead switch 3. When the member 4 collides against the stopper 6 to spring back, resistance by fluid friction increases to delay a return back. Further, vibration of the member 4 due to colliding against the stopper 6 is absorbed and dispersed by the liquid 8. Accordingly, chattering of the switch 3 is suppressed, to lengthen a closing time of the read switch.
