Patent JP-S5870082-A (JP)
Title: Screw compressor
Inventor: NAGATA KIMIO
IPC: F04C18/16
Filed: 1981-10-23
Abstract: PURPOSE:To keep the surface of oil sealed in a screw compressor at an optimal level and to prevent occurrence of oil rise, by employing such an arrangement that the level of the oil surface in an oil separator is less than 1/2 of the height of a discharge port of the compressor from the bottom of the oil separator and a gas outlet port of the oil separator is located at a position higher than said discharge port of the compressor. CONSTITUTION:During compression cycle, compressed gas mixed with oil is separated into oil and gas at a demister 10 and oil thus separated forms an oil surface 11 at the bottom of an oil separator 8. When the oil surface 11 is raised near to a gas outlet port 9, droplets of oil are carried together with gas by the gas flow, so that oil rise is caused. In order to overcome the above difficulties, the distance H from the oil surface 11 to the center of a discharge port 7 of a compressor is selected to be smaller than 1/2 of the distance K from the bottom of the oil separator 8 to the center of the discharge port 7. At the same time, the gas outlet port 9 of the oil separator 8 is located at a position higher than the discharge port 7. With such an arrangement, it is enabled to keep the oil surface in the oil separator 8 at an optimal level and hence to prevent occurrence of oil rise.

Title: Thermal head and preparation thereof
Inventor: HAMAMURA KIYOTO
IPC: B41J2/335
Filed: 1989-06-30
Abstract: PURPOSE:To achieve miniaturization and wt. reduction by obtaining sufficient electric capacity as a common electrode without increasing a film thickness by forming notch parts to both corner parts of the side surface of an insulating substrate along the parallel arrangement direction of heating elements and forming a part of the common electrode to the side surface and the end surfaces of the notch parts. CONSTITUTION:An insulating substrate 15 composed of ceramics has such a shape that two corner parts at both ends of the long side of a rectangle are notched into a triangular shape and a plurality of individual comb-shaped electrodes 16 are formed to the central part of the main surface of the insulating substrate and a common electrode 17 is formed therearound. A glaze layer 25 is formed to the surface of the insulating substrate 15 and a resistance film 26 for forming heating elements 20 is formed on the glaze layer 25 and individual electrodes 16 and membrane electrode parts 18 are further formed thereon. A plurality of substrates 27 are successively superposed one upon another while three end surfaces thereof are laterally shifted little by little in parallel and particles 28 of a dry film metal are deposited thereon to form a common conductor part 19. Since the common conductor part 19 is formed not only on the main surface of the substrate but also on three end surfaces thereof, the miniaturization of a thermal head can be achieved without reducing the electric capacity of the common electrode 17.

Title: Fuel injection device for engine
Inventor: ARAI TAKAYUKI
IPC: F02M51/06
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent an initial fuel injection completely by forming a valve means for closing a back pressure passage for leading fuel supply pressure, which is formed at a back pressure chamber expanded or contracted according to the expansion or contraction of a magnetostrictive actuator as fuel supply pressure rises, at the back pressure passage. SOLUTION: At the time of engine stopping, a piezo-actuator 10 contracts, so that the pressure of a fuel pressure chamber 3 and a back pressure chamber 8 drops and a needle valve 2 closes a nozzle hole 1a with a return spring 4. A spool valve 30 opens a back pressure passage 32 with the return spring. When a fuel pump is driven to start an engine, pump delivery pressure is led to the back pressure chamber 8 immediately, however, the pressure rise of the fuel pressure chamber 3 is delayed by the pressure rise of the back pressure chamber 8 through a second restriction passage 39, so that the needle valve 2 is forced in the valve-closing direction by the pressure difference between the fuel pressure chamber 3 and the back pressure chamber 8. It is thus possible to prevent an initial injection symptom that the needle valve 2 opens and fuel is injected before the engine starts.

Title: Antithrombogenetic medical material and production thereof
Inventor: NOISSHIKI YASUHARU
IPC: A61K38/16
Filed: 1985-07-31
Abstract: PURPOSE:To produce a large amount of an antithrombogenetic medical material at a low cost, by coating or impregnating a collagen-containing solution to a synthetic polymeric material and immobilizing protamine to the collagen with a crosslinking agent, thereby heparinizing the collagen. CONSTITUTION:A collagen-containing solution is coated to or impregnated in a synthetic polymeric material (e.g. polyurethane, polyvinyl chloride, etc.), and protamine is immobilized to the collagen with a crosslinking agent (e.g. hexamethylene diisocyanate), thereby bonding heparin to protamine to effect the heparinization of collagen. The objective antithrombogenetic medical material containing heparinized collagen integrated to a synthetic polymeric material can be produced by this process. A large amount of the objective medical material having excellent antithrombogenetic property, cell affinity, physical strength and uniformity can be produced at a low cost by integrating heparinized collagen with a synthetic polymeric material.

As a result, the part continuing to the recessed part 11 formed at the base end of the rim 7 is pressed inwards by the bulging part 16 and projecting bar 17 of the die 14 and with being press-contacted to the recessed groove 15 of a punch 12 a spline tooth is formed by ironing. At this time, due to the recessed part 11 being formed at the base end of the rim 7 the generation of a big resistance in forming is prevented and the spline tooth can correctly be formed.

IPC: H01L21/3065
Filed: 1986-07-18
Abstract: PURPOSE:To execute excellent etching working forming a superior shape with excellent reproducibility in an etching process at the time of the manufacture of a semiconductor device, particularly, a trench etching process, by exposing the surface of silicon carbide conducting with an electrode to one part of an insulator coating the surface of the electrode on which an article to be etched is placed. CONSTITUTION:An article to be etched 4 is placed onto one of a pair of counter high-frequency power applying electrodes 2, 3 arranged into a reaction vessel 6 capable of being evacuated, and the article to be etched 4 is etched by reactive gas plasma. In such an etching device, the surface of silicon carbide 7 conducting with the electrode 3 on which the article to be etched 4 is placed is exposed to one part of an insulator 51 coating the surface of the electrode except a base section in the electrode 3. Consequently, since the surface of silicon carbide 7 conducts with plasma in a DC manner, the surfaces of the insulator 8 coating the electrode 3 and a formed deposit are made difficult to be charged, thus generating no abnormal discharge by break down, etc. Accordingly, self-bias voltage is not fluctuated, thus acquiring an etching result forming an excellent shape high superior reproducibility.

Filed: 1988-07-07
Abstract: PURPOSE:To increase an effective heat transfer area to liquid refrigerant and to accelerate a boiling heat transfer by opening refrigerant passage hole row formed as a gear train in the inner wall face of a hole along the contact face with a semiconductor element in a cooler. CONSTITUTION:A plurality of refrigerant passage holes 34 are opened at the center of a cooler 35 in its thickness direction along the contact face 31 of a semiconductor element. The hole 34 is formed with female threads, and female threadlike gear train 33 are formed on the inner wall face of the hole. When the heat generated at the element is transferred to the cooler 35 through the face 31, a heat transfer occurs by convection to the refrigerant in contact therewith. If the wall face of the cooler 35 is at the saturation temperature or higher of the liquid refrigerant, the refrigerant is surface boiled to generate air bubbles on the wall face, and boiling heat transfer occurs. On the other hand, the temperature of the refrigerant filled in the hole 34 is raised by the heat transfer from the cooler 35 thereby to generate liquid density difference in upper and lower parts in a vessel, so-called a chimney effect is operated to rise the liquid refrigerant in the hole 34.
