Title: Manufacture of semiconductor device
Inventor: KONO YOSHIO
IPC: H01L21/76
Filed: 1989-05-30
Abstract: PURPOSE:To form an isolating oxide film at a region deeper than the main surface of a semiconductor substrate so as to prevent narrow channel effect by thermally oxidizing a silicon layer, which is formed selectively in the recess of the semiconductor substrate, so as to form an isolating oxide film. CONSTITUTION:The second polycrystalline silicon layer 11 is formed only in a groove 10 provided at a P-type silicon substrate 1. Next, by applying thermal oxidation, an isolating oxide film 7 is formed. At the same time with this, by boron, to which ions are implanted, thermally diffusing, a channel stopper layer 6 consisting of a p<+>-type impurity region is formed under the isolating oxide film 7. This way, n-channel MOS transistors, wherein elements are isolated by the isolating oxide film 7, are formed. For the shape of the isolating oxide film 7, it is the shape of projecting downward into the silicon substrate 1. For that reason, the depletion layer of each n-channel MOS transistor separated by this isolating oxide film 7 becomes hard to extend.

Title: Water-tight structure of door
Inventor: USHIMARU TEI
IPC: E06B7/22
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent rainwater accumulated in the lower frame from splashing and entering the indoor side by wind pressure. SOLUTION: A water-tight material 21 in attached sideways to the vertical middle part of a vertical face 31 of a lower frame 11 and arranged to butt against a vertical water-tight material 22 attached to a vertical frame 12. When the door is closed, a lateral water-tight material 21, the vertical face 31 and the door form a recess in which rainwater is accumulated. A water-tight sponge member 50 is put to contact the lateral water-tight material 21 and the vertical water-tight material 22 to close the gap of the butt part. In this way, since wind pressure acting on the gap does not directly act on the indoor side, the pressure is attenuated. And hence, the structure prevents rainwater accumulated in the recess from splashing and entering the indoor side.

IPC: F16C17/10
Filed: 1992-05-28
Abstract: PURPOSE:To facilitate a low-torque/high-speed rotary driving and improve the accuracy of shaft whirling and the accuracy of rotation by a method wherein a radial load is received by a pneumatic dynamic radial bearing and a thrust load is received by a pivot-type thrust bearing. CONSTITUTION:A bearing bush 2 and a thrust receiving part 7 are made of ceramic material such as silicon nitride, silicon carbide, zirconia or alumina. The material of a rotary shaft 8 is quenched stainless steel. Therefore, when the rotary shaft 8 starts rotary driving, ring-bone trenches of which dynamic pressure bearing parts 16 and 17 are composed are made to rotate and, accordingly, air 15 enclosed by the flange part of a bearing housing 1 and an air-tight structure 14 is sucked through a bearing gap between the rotary shaft 8 and the bearing bush 2 and a pressure in the bearing gap is elevated. As a result, if the revolution of the rotary shaft 8 reaches a predetermined revolution, the outer circumference of the rotary shaft 8 and the inner circumference of the beating bush 2 are brought into a non-contact state with each other with the air 15 which is lubricant fluid therebetween.

Filed: 1980-09-30
Abstract: PURPOSE: To perform transfer of a plate at high speed, by providing a braking roller in the vicinity of an outlet of pinch rollers and decreasing colliding speed of the plates to the stopper of a piler.  
     CONSTITUTION: A steel plate 4 is transferred by a horizontal belt conveyer 1, put between pinch rollers 3a, 3b and then fed to a piler 5. A driving brake roller 9 is provided in the vicinity of said pinch rollers, and if circumferential speed of this roller 9 is arranged slower than speed of the rollers 3a, 3b, the steel plate 4 is reduced its speed by the roller 9 before colliding against a stopper 7 of the piler 5. Accordingly, the steel plate 4 is moved at low speed when piled to the piler even if fed at high speed, thus damage in an end part of the plate can be prevented.

Abstract: PURPOSE:To detect a very minute amount of contaminant by forming a hydrofilic film on the surface of a planar body, dropping liquid droplets, measuring the initial contact angle, leaving the film alone in an atmosphere to be inspected, and measuring the contact angle of the liquid droplet again. CONSTITUTION:The surface of a silicon (Si) plate 10 has the adsorptivity. The surface is polished. The silicon plate 10 undergoes SC1 treatment. The interface state of an SiO2 film 11 has the hydrophilic property. An inspecting plate 12 on which the SiO2 film 11 is formed is prepared. Water droplets 13 are dropped on the surface of the inspecting plate 12, and an initial contact angle theta1 is measured. Then, the droplets are removed, and the inspecting plate 12 is left alone in a clean room for fabricating semiconductors for about one week. Then, water droplets 13 are dropped again on the upper surface of inspecting plates 12A and 12B. After the plates are left alone, the contact angle theta2a and theta2b are measured. The differences between the initial contact angle theta1 and the contact angles theta2a and theta2b after the plates are left alone are inspected. When the difference is found, it is judged that the very minute amount of the contaminant is contained in the atmosphere.
