Title: Surface stabilizing process for semiconductor element
Inventor: WATANABE TOKUO
IPC: H01L21/314
Filed: 1981-09-18
Abstract: PURPOSE:To materialize surface stabilization with high reliability by a method wherein an inorganic compound is coated on the surface exposed a p-n junction  section after forming an electrode on a semiconductor substrate. CONSTITUTION:A supporting base 22 and a laser output terminal 9 are positioned so that a laser beam 8 may irradiate at only the bevel face 7 of a semiconductor element 10 and laser is aimed at the bevel face 7 through a quartz window 21. The used laser beam is the switching pulse beam of ruby laser. Furthermore, the laser beam is used by closing the beam diameter to 30mumphi by using a lens. In this way, the irradiation of laser beam locally heats only the surface of the irradiated part to generate the chemical reaction of atmosphere gas (SiII4 and O2) and an oxide film (SiO2) 30 is grown the surface. An arbitrary film can be grown by suitably changing irradiation time and atmosphere gas pressure.

Title: Antiskid apparatus
Inventor: FUJITA TOMOHIRO
IPC: B60T8/48
Filed: 1979-11-12
Abstract: PURPOSE: To improve re-elevating property of a brake liquid pressure during the antiskid control by tapering a valve shaft of a throttle valve interposed in a pipeline connecting a chamber arranged in contact with a brake device of an antiskid controlling valve and the source of liquid pressure.  
     CONSTITUTION: When the input of an antiskid signal S 1  is stopped, a ball 19 is left staying on a valve seat 18 keeping a valve shaft 1 meeting the ball 19. A liquid pressure from a master cylinder 2 is transmitted to a liquid chamber 7 connected to a brake device of a skid control valve 4 by way a throttle valve 9. At this point, a thrust works on the valve shaft 30 in the direction of an output liquid chamber due to a liquid chamber due to a liquid flow when a pressure liquid runs to the output liquid chamber 26 at a low pressure from an input liquid chamber 25 at a high pressure. As a result, the valve shaft 30 moves the left to reduce a clearance between a tapered section 31 and a valve seat 27. As the differential pressure between the output liquid chamber 25 and the input liquid chamber 26 grows, the thrust increases thereby further decreasing the clearance.
