Title: Dust proof cover used in common for mask of video camera
Inventor: IGUCHI TOMOMI
IPC: H04N9/09
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To integrate a mask for shutting off undesired light made incident onto a color resolving optical system with a cover for dust proof of an optical filter and to prevent a ghost and a flair from generating due to scattered light at an edge of an opening that controls an optical pass area. SOLUTION: An opening 42 to control a passing range of light entering to a color resolving prism 20 is formed to a dust proof cover 40 that surrounds a back side of a neutral density(ND) filter 24 and a color temperature conversion filter 26. A slope is formed so that an inner peripheral face 43 of the opening 42 spreads an aperture area in a thickness direction of the dust cover 40 from an entering face side of the light toward an emission face side. Thus, the undesired light reflected on the inner peripheral face 43 is largely deviated from an incident optical axis of the color resolving prism 20 to prevent a ghost and a flair. Furthermore, an aluminum material is adopted for a material of the dust proof cover 40 and the reflection is more effectively prevented by applying black alumite processing to the entire parts.

Abstract: PURPOSE:To obtain an etching mask which has good adherence with an insulating film and a semiconductor material by heat treating the film formed on the prescribed semiconductor substrate in hydrogen or inert gas atmosphere, and then surface treating with hexamethyldisilazane vapor. CONSTITUTION:A PSG-SiO2 film 6 which contains phosphorus is adhered by a CVD method to the surface of a surface layer 5. Then, the film 6 is heat treated in hydrogen atmosphere. Then, the film 6 is surface treated in vapor of organic surface active material such as hexamethyldisilazane, thereby converting the surface of the film 6 to hydrophobic property. Then, after a photoresist is coated on the film 6, it is exposed in the prescribed pattern to form a resist pattern, and the film 6 is opened in a window with dilute solution of fluoric acid. Since the surface of the film 6 is converted with hexamethyldisilazane into hydrophobic property, the film has good adherence with the photoresist. When the window is opened, it does not impregnate HF into the boundary surface between the resist and the oxidized film, thereby accurately opening the window pattern.

Title: Piston
Inventor: ISSHIKI NAOJI
IPC: F16J9/10
Filed: 1989-03-07
Abstract: PURPOSE:To improve sealing performance at compression stroke and reduce friction loss and abrasion loss at suction stroke by inserting a back-up ring made from heat resistance rubber to discharge flow-in gas on the back of a piston ring and prevent gas leak through sealing the gap of the ring, between the piston ring and the bottom of a ring groove. CONSTITUTION:When a piston is used as the double acting type piston of a reciprocating gas compressor, compressed gas flowing in from the clearance between a piston ring groove 11 and a piston ring 12 flows in the U-shaped ravine 130 of a back-up ring 13 made from heat resistance rubber. As the gas presses the outer circumferential face 132 of the ring 123 to the back 121 of the piston ring, the compressed gas flowing in the ravine 130 does not leak from the gap of the piston ring 12. Further at suction stroke, a clearance is generated between the back 121 of the piston ring and the outer circumferential face 132 of the back-up ring, hence remaining compressed gas in the ravine 130 is released through the clearance.

Abstract: PURPOSE:To obtain excellent preserving life and operational life and to make it possible to maintain excellent response, by forming an intermediate layer between an insulating material covering a part of a conductive electrode and an ion sensitive film which is formed on a part that is not covered with the insulating material. CONSTITUTION:An intermediate layer 4 is formed between an insulating material (polyvinyl chloride) 3 covering a part of a conductive electrode (silver electrode whose surface is covered with silver chloride) 2 and an ion sensitive film (comprising polyvinyl chloride, dioctyl adipate, tetrahydrofuran and the like) 5. Thus, the contact part between the insulating material 3 and the sensitive film 5 is made small at the intermediate layer incorporating electrolyte (potassium chloride and the like). Therefore movement of additive in the sensitive film 5 into the insulating material 3 is suppressed, and deterioration is prevented. As a material for the intermediate layer 4, a high- hydrophilic polymer such as polyacryl acid and the like and their derivatives whose affinity to the additive in the sensitive film 5 is poor is suitable. In order that adhesion between the sensitive film 5 and the electrode 2 is not deteriorated, a part of the insulating film 3 is formed so that the sensitive film 5 directly comes into contact with the insulating material 3.
