Title: Oil ring with expander
Inventor: UMEZAWA KOJI
IPC: F02B1/04
Filed: 1995-03-27
Abstract: PURPOSE: To provide a light-weight oil ring which is superior in oil scraping performance and has durability by arranging a plate expander which contacts with internal faces of upper/lower rings, in the insides of the upper/lower rings which is convex in its internal/outer circumferential faces and symmetrical in its top/bottom in section. CONSTITUTION: Oil ring which are made of steel are convex in their internal/ outer circumferential fades and symmetrical in their top/bottom in section, the upper ring 2 and lower ring 3 are vertically arranged, and a U-sectional plate expander 5 is sandwiched between the intermediate insides of both rings 2, 3. Both rings 2, 3 are pressed outward against the inside wall 71 of a cylinder 7 by the plate expander 5 and at the same time pressed vertically, because the internal faces are convex and inclined, so that a side clearance toward a ring groove 61 of a piston 6 is eliminated. This constitution can improve sealing performance on the top/bottom faces of the ring groove 61 and save oil consumption.

Title: Liquid specimen dispenser
Inventor: SUGANO KENJI
IPC: G01N35/10
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To surely spread a trace liquid specimen all over the bottom part of a specimen vessel and enable dispensing, by starting the spouting of liquid specimen, in the state that the downstream side part of a specimen vessel aperture is positioned at a spouting position, viewed from the transfer direction of the specimen vessel. SOLUTION: The downstream side part of an aperture of a well 3 (specimen vessel) viewed from the transfer direction of a blood serum tray 2 is positioned at a sample spouting position S2. In this state, a dispensing means 8 and a transferring means (a conveyer belt 9 and a transferring motor 10) are controlled by a control means 7 so that the spouting of liquid specimen may be started. Since the vessel aperture is stopped at the downstream part to each well 3 and isolating injection is started, the specimen spreads effectively as far as corners of the downstream part. After that, the well 3 is transferred while the specimen is spouted, so that the specimen spreads effectively to the central part of the well 3, by the inertia acting on the specimen spouted during transferring and the stretching action of the specimen by a probe 13.  The specimen spreads as far as the corners also in the upperstream side part of the well 3.

Abstract: PURPOSE:To improve mechanical strength, insulating resistance, and dielectric strength, and obtain a constant capacitance by forming a common electrode on one surface of a grain boundary or surface layer insulating type semiconductor porcelain substrate, forming individual electrodes on the other surface, while constituting the individual electrode of a fixed electrode and an area adjusting electrodes which are electrically conductive with each other. CONSTITUTION:A common electrode 32 is formed on one surface of a dielectric porcelain substrate 31; a plurality of individual electrodes 33 are formed on the other surface; the individual electrode 33 is constituted of a fixed electrode 34 occupying a greater part of the electrode area and an area adjusting electrode 35. As a result, by the area adjusting electrode 35, the electrode area of each capacitor in each porcelain substrate 31 or one porcelain substrate 31 can be finely adjusted in response to the irregularity of substrate thickness, so that the irregularity of electrostatic capacitance caused by the irregularity of thickness can be corrected. Since grain boundary of high dielectric constant or surface layer insulating type semiconductor is used as dielectric, the electrostatic capacitance can be made large even in the case of a thick substrate. Thereby, constant capacitance is obtained, and mechanical strength, insulating resistance, and dielectric strength of the porcelain substrate 31 can be improved.

Abstract: PURPOSE:To prevent intrusion of bird's beaks into an element region and to improve the degree of integration of a device by composing a first oxidation- resistant insulating film of a compound of Si, O and N as major elements. CONSTITUTION:The film of the intermediate compound (silicon oxynitride) of an SiO2 film and an Si3N4 film is used as a first oxidation-resistant insulating film. Consequently, when the oxynitride film is employed, intrusion into an element region of bird's beaks at the time of selective oxidation can be prevented by thickening the film thickness of oxynitride, and membrane stress is made smaller than an Si3N4 film formed through a CVD method, thus obviating the occurrence of a crystal defect in an Si substrate on selective oxidation, then reducing the leakage currents of a semiconductor element. Accordingly, the degree of integration of a semiconductor device is improved, and the leakage currents of the semiconductor element are lowered.
