Title: Lost wax casting method
Inventor: KAWAMOTO MASASHI
IPC: B22C9/04
Filed: 1986-10-23
Abstract: PURPOSE:To increase the solidifying rate on the inside of the hollow part of a casting mold and to prevent the generation of casting defects by backing up the hollow part with a backup material having a relatively small grain size. CONSTITUTION:A ceramic mold 2 is charged in a red hot state into a casting box 1 made of iron and after the backup material 3 is packed around the mold 2, a molten metal is poured into the mold 2. The material 3 is different in the grain size from steel shot 6 packed in the hollow part 5 of the mold 2 and steel shot 7 packed on the outside of the mold 2. The steel shot 6 of a relatively small grain size is packed into the hollow part 5. The packing density thereof is thereby increased and the heat on the inside of the hollow part 5 is quickly transmitted to the outside, by which the solidifying rate is increased and the formation of the coarse crystal grains or the generation of the casting defects is prevented.

Title: Josephson junction device
Inventor: SHINADA MEGUMI
IPC: H01L39/24
Filed: 1991-09-30
Abstract: PURPOSE:To adjust a junction critical current in a state of a title device where it is cooled at operation temperature by laminating a water-absorbing or hygroscopic porous inorganic film on a superconducting thin film CONSTITUTION:A lower electrode 2 and an upper electrode 4 are weakly joined with each other through a bridge 5, where a Josephson junction is formed. A porous SiO2 deposition film 6 is formed on the surface of the bridge 5. For adjusting a junction critical current of the device, water is adsorbed in the SiO2 film 6 and the device is dipped in liquid helium to permit a current greater than the critical current to flow through the bridge 5. Hereby, the bridge 5 Produces heat to release water from the SiO2 film 6. The water makes contact with the surface of the bridge 5, and a contact portion is oxidized to lower the critical current through the bridge 5. Thereafter, in the case where the critical current exceeds a desired value, the process is repeated to adjust the junction critical current.

Title: Isolation structure of semiconductor element
Inventor: KAWAMURA AKIO
IPC: H01L21/762
Filed: 1988-10-05
Abstract: PURPOSE:To prevent a disconnection and a short circuit of a wiring part by a method wherein the surface of a silicon film formed by filling a groove is covered with a silicon oxide film formed by oxidation. CONSTITUTION:A polycrystalline silicon film 9 is deposited by filling a groove 8 by a low-pressure CVD method; after that, the polycrystalline silicon film 9 is etched and removed by an RIE method until a silicon nitride film 6 is exposed. As a result, the polycrystalline silicon film 9 which has been filled inside the fine groove 8 is left; in addition, the surface of the polycrystalline silicon film 9 is oxidized thermally by a thermal oxidation method; a silicon oxide film 10 is obtained. Since the surface of a silicon substrate 1 and an inner wall of the groove 8 are covered with the silicon nitride film 6 in this case, a spread in a transverse direction of an isolation region as is caused in a selective oxidation method is not caused. Thereby, it is possible to prevent a disconnection of a wiring part and a short circuit between wiring parts formed on the isolation region.

Title: Heater for acidic liquid
Inventor: HOTSUTA MINORU
IPC: C23F13/00
Filed: 1993-09-13
Abstract: PURPOSE:To raise the temp. of an acidic liquid by heating the liquid over a long period of time without corroding a heat exchanger having a specific structure by inserting this heat exchanger as an anode and a Pt cathode into a tank contg. the acidic liquid and energizing both electrodes. CONSTITUTION:The heat exchanger S as the anode and the Pt electrode 6 as the cathode are inserted into a PVC coating bath tank T incorporating a corrosive acidic liquid H contg. an acid, such as sulfuric acid, nitric acid, etc. The acidic liquid H is energized through both electrodes S and 6 from a current rectifier 9, by which the acidic liquid H is heated. The heat exchanger S as the anode is composed of an outside pipe 1 and an inside pipe 2 therein and the heat medium is introduced from an inlet 4 and is discharged from a drain pipe 3 after the heat exchange. A scientifically inert passivated film 1T is formed on the surface of the heat exchanger S as the anode by energization and the corrosion by the acidic liquid H is extremely suppressed as the heat exchanger S is protected by such a film. The heat exchanger is thus capable of heating the acidic liquid H over a long period of time.

Title: Valve lifter and variable valve system for three- dimensional cam
Inventor: NAKANO SHUJI
IPC: F01L1/20
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To improve the durability of a valve lifter and a variable valve system for a three-dimensional cam by enhancing the degree of freedom for designing a detent mechanism of the valve lifter for the three-dimensional cam. SOLUTION: A thick wall part 19j is made up by an offset D1 lying between an outer circumferential surface 19a and an inner circumferential surface 19f of a valve lifter 19 and the other parts are formed into being thinned. Therefore the thick wall part 19j being sufficiently thickened is formable without increasing most of weight. Accordingly a sufficient sized projection 19b is attached to the valve lifter 19 without causing any distortion in the lifter 19, and thereby a contact area to a detent groove 9b is increased, making any surface pressure reducible, and thus durability is improvable in the way. Since the thick wall part 19j exists lengthily in the axial direction of the valve lifter 19, a detent mechanism is formable on the outer circumferential surface 19a of the valve lifter 19 even in case of being not in the vicinity of a top surface 19k.  Consequently the degree of freedom for designing the detent mechanism is promoted.
