Title: Temperature compensating device for hydraulic control
Inventor: HIRAMATSU TAKEO
IPC: F15B21/045
Filed: 1982-07-29
Abstract: PURPOSE:To prevent a controlled hydraulic pressure from being affcted by variation in temperature, by providing a thermovalve serving to relieve an oil passage of a pressurized oil at a low oil temperature where viscosity of the pressurized oil is increased. CONSTITUTION:A thermo valve 5 is inserted into an oil reservoir at its one end, wherein there is incorporated wax expanding and contracting in dependence upon variation in temperature. A rod is slidably inserted through two vertically- separated oil chambers and is fixed integrally with valve members 5a and 5b, an end of the rod being inserted into the wax. Accordingly, the rod is slided by the contraction of the wax at a low oil temperature, and the valve member 5a opens a branched oil passage 2a to relieve the oil passage 2a of the pressurized oil. At the same time, the valve member 5b opens a bypass oil passage 2b to widen an oil communication area. With this arrangement, a controlled hydraulic pressure is prevented from being affected by variation in temperature, thereby achieving a suitable hydraulic control over the range of low to high temperature.

Title: Radiation sensitive resin composition and formation of resist pattern using the same
Inventor: ITO TOSHIO
IPC: G03F7/004
Filed: 1995-05-30
Abstract: PURPOSE: To obtain a radiation sensitive resin compsn. with which easy processing of high melting metals is made possible and the simplification of production stages is made possible by incorporating a specified compd. therein. CONSTITUTION: This radiation sensitive resin compsn. contains poly(titanoxane) having R-O-Ti bonds (R denotes an alkyl group) at every monomer unit and an acid generating agent which is decomposed to generate an acid by the effect of radiation. The poly(titanoxane) contained in the radiation sensitive resin compsn. forms silanol by catalytic reaction with the acid, thereby forming an inorg. polymer having much titanic acid. The resulted inorg. polymer having much titanic acid gelated and does not dissolve in a solvent any more. The parts where the silanol is formed by the acid generated from the acid generating agent do not dissolve in a developer and the parts which do not react with the acid dissolve in the developer and, therefore, the compsn. is usable as a material for resift patterns.

Title: Core substrate for magnetic head and production of magnetic head
Inventor: IKEDA YOSHITO
IPC: G11B5/23
Filed: 1992-04-27
Abstract: PURPOSE:To enable the easy impartation of an azimuth angle in cutting in the joining direction of a substrate by diagonally joining plural core substrates for magnetic heads at the same angle of inclination as the azimuth angle to be imparted to the magnetic gaps of the magnetic heads. CONSTITUTION:Glass powder (not shown in Fig.) is inserted into respective joint surfaces and the substrates are superposed on each other diagonally via magnetic metallic films (not shown in Fig.) by having the same angle theta of inclination as the azimuth angle to be imparted to the magnetic gaps of the magnetic heads. As a result, the effective thickness Ly at the time of cutting is made into Lcostheta-2.tsintheta (where t is the thickness of the core substrate 1 for the magnetic heads). The effective thickness Ly at the time of cutting is Lcostheta-Lsintheta in the conventional method and, therefore, the difference from the value of this invention is -2.tsintheta+Lsintheta. Then, the effective thickness Ly is proportional to the length L on one side in the conventional method but is proportional to 2.t in the example of this invention. In general, t is extremely smaller than L and, therefore, the effective thickness Ly is larger with this invention.

Abstract: PURPOSE:To enable the protection of a surface facing an opening of a semiconductor substrate by a method wherein an oxide film formed on the surface in the opening of the semiconductor substrate is removed, an oxidation resisting film is formed thereafter on the surface facing the opening of the semiconductor substrate, and then the inside surface of the opening is oxidized to form an oxide film. CONSTITUTION:A polycrystalline silicon layer 2 and a silicon oxide film 3 are formed on an N-type semiconductor substrate 1, and an opening 4 for forming a base region is formed by etching. Thereafter P-type impurities are ion-implanted into the surface of the semiconductor substrate 1 through the opening 4, so as to form the base region 5. When the surface of the semiconductor substrate 1 is heat-oxidized subsequently, an oxide film 6 is formed on the inside surface of the opening 4 of the polycrystalline silicon layer 2 and on the surface of a part facing the opening 4 of the semiconductor substrate 1. Then, the part of the silicon oxide film 6 formed on the surface of the semiconductor substrate 1 is removed by anisotropic etching, a silicon nitride film 7 is formed on the surface of the semiconductor substrate 1, and a side wall 8 is formed on the inside surface of the opening 4 of the polycrystalline silicon layer 2. Accordingly, it can be avoided that the surface of the semiconductor substrate is damaged by anisotropic etching.

Filed: 1990-05-22
Abstract: PURPOSE:To restrain the development of heat crack by arranging plural recessed holes having the specific length of almost parallel part at bottom part, arranging the specific radius of continuous standing up part and specifying the depth on surface of a roll. CONSTITUTION:Plural recessed holes 2 having >=1mm length of almost the parallel part 3 at the bottom part and also >=0.02.D/2 (D: roll diameter) the radius R continued to the bottom part around this bottom part of the standing up part 4 and >=1mm the depth (h) are arranged on the roll surface. As the roll 1 is always brought into contact with a cast slab, etc., through gap with the recessed holes 2, roll surface temp. is remarkably lowered in comparison with the ordinary flat roll. Therefore, thermal stress in the roll is drastically lowered. Further, the stress by only quantity, which the thermal expansion at small part of the recessed hole is restricted, is developed and made to lower compared with the stress developed to the ordinary flat roll. By this method, the development of heat crack is restrained and trouble of roll breakage, sleeve cracking, etc., can be prevented.

Title: Berthing speedometer for ship
Inventor: SAITO HIROSHI
IPC: G01S15/42
Filed: 1989-05-25
Abstract: PURPOSE:To allow the selection of prescribed wave transmitter/receivers in correspondence to a tidal level range and to avert a defective measurement by adopting the constitution in which the tidal level data from a detector by the torque balance with a float successively operates switches via a driving mechanism having a blind zone. CONSTITUTION:The berthing speedometer for ships is fixed at both ends to mounting plates 4 disposed at two points in the prescribed positions in the sea bottom and on the sea. The position of the float 1 which is guided by a perpendicularly provided guide wire 2 and floats on the sea surface changes according to the change in the tidal level. The other end of a tidal level wire 3 fixed to the float 1 is connected to a detector 5 which winds a fixed torque spring by the driving power thereof to balance the torque. The float 1 stays still in the position where the torque is balanced by the weight of the float 1 itself, the sp. gr. of the sea water and the spring torque. The tidal level wire 3 of the detector 5 is wound up by the motor of the specified torque over a long stroke upon changing of the tidal level. The float 1 is thus held always in the balanced position on the sea surface. The output of a pinion gear 6 is transmitted to a driving mechanism 7 having the blind zone so as not to respond to the fluctuation in the tidal level by waves.
