Inventor: OMORI SEIJI
IPC: E04G21/14
Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To reduce a burden to a structure which is being built, and a burden to a lift device in a jack or the like so as to build a mid-to-high-rise building structure in a push-up construction method even with a small scale device, and reduce the cost for building a structure and the cost of withdrawal of the device after completion of the building in a narrow space between buildings already built or the like. SOLUTION: A temporarily built reaction frame 4 is composed of at least four posts 4V arranged between permanent posts 2 in a structure 1 to be built and formed therein with pin holes at equal intervals, and beams 4H bridging between these posts 4V. A permanent side beam 3B of the structure 1 is supported by a jack 5 adapted to be moved vertically along the posts 4 in the temporarily built reaction force frame 4 while it is lifted up. Accordingly, the permanent cross beam 3A of the structure 1 is laid for spanning on the joint beam 4H of the frame 4 while a beam part is built. Then concrete is placed while the permanent post 2 is erected in a lower story. With the repetitions of the above-mentioned steps, several stories are successively built.

Title: Polishing method for cylindrical body
Inventor: NISHIKAWA MASAKI
IPC: B24B1/00
Filed: 1988-09-02
Abstract: PURPOSE:To polish the outer diameter face of an extremely slender flexible cylindrical body with high accuracy by taking the apparent curvature elasticity of a polishing core at >=40000kg/mm<2> Young's modulus. CONSTITUTION:In case of inserting a polishing core 2a being inserted into a cylindrical body 1 consisting of the flexible materials of a rubber, etc., and polishing the outer diameter face thereof by a grindstone 3, those which have an apparent curvature elasticity at >=40000kg/mm<2> Young's modulus are used as a polishing core 2a. By using the polishing core 2a whose apparent curvature elasticity is at >=40000kg/mm<2> Young's modulus like this, there is hardly any such fear as causing core bend and core deflection by being beaten by the grindstone pressure. Also, polishing of high accuracy can be executed by holding one end of the polishing core 2a by a chuck 5 and holding the other end by the bearing hole 6a of a bearing jig 6.

Title: Radial bearing device
Inventor: UNO SHUETSU
IPC: F16C17/03
Filed: 1993-09-03
Abstract: PURPOSE:To provide a radial bearing device improved in terms of efficiency and reliability, while ensuring high workability, safety and economy as well as the enhancement of efficiency and reliability. CONSTITUTION:The slide surface of tilting pads T1 to T6 for supporting a journal 1 in such state as freely slidable is formed out of a glass fiber charged PTFE plate 26.

Title: Production of inorganic foamed material
Inventor: HANEDA SATORU
IPC: C04B38/00
Filed: 1987-09-02
Abstract: PURPOSE:To obtain a foamed material which fluctuates less in quality and has excellent mechanical strength by preparing a water dispersion dispersed with an intimate mixture contg. a hydraulic material and mixing the water dispersion and low melting point liquid, then foaming the mixture. CONSTITUTION:The water dispersion which contains the intimate mixture contg. the hydraulic material and is set at the temp. higher than the b.p. of the low melting point liquid when mixed with the low melting point liquid is prepd. The low melting point liquid and the water dispersion are then mixed and foamed. The volume shrinkage after the hydration and curing of the hydraulic material is thereby obviated and the rigidity and mechanical strength of the foamed material are enhanced. Since the low melting point liquid and the water dispersion are respectively discretely prepd., the evaporation of the low melting point liquid is suppressed and the dispersibility of the intimate mixture in the water dispersion is enhanced. The water dispersion uniformly dispersed with the intimate mixture is thus obtd.

Title: Thermal recording head
Inventor: KANEKO AKINARI
IPC: B41J2/355
Filed: 1983-11-21
Abstract: PURPOSE:To obtain a long-life thermal recording head free of sticking by controlling voltage to be applied to heating elements by elements whose electric resistance values are altered accoding to temperatures. CONSTITUTION:While a pulse voltage is applied, the pulse voltage V to be applied between an earth electrode 9 and a signal electrode 10 is constant, and a voltage VR to be applied to both ends of the resistor R of a heating element 2 and a voltage Vr to be applied to both ends of a resistor (r) are in a relative relation in which when one is higher the other is lower. When the resistance value of the resistor (r) is raised by the rise of temperature, the voltage Vr is raised, and the voltage VR is lowered. The maximum temperature of the heating element 2 can thus be controlled lowly and the detrioration and sticking of the heating element and the rise to high temperatures of the heating element can be prevented. Small-size, long-life thermal recording heads having lesser trouble can be obtained accordingly.

Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To easily and effectively suppress the depression of an active region and to refine the region by conducting exposure with the use of a mask having a recess, a protrusion or a dummy pattern at the part corresponding to the corner of the active region on the mask. SOLUTION: A mask 7 having a recess 7d in such a size that it is not resolved by lithography at the part corresponding to the corner of an active region 1 on the mask is used in exposure. This recess 7d is square, and the two sides holding the rightangle part are paralleled to the two sides of the corner and allowed to intrude into the corner somewhat deeply. Accordingly, the light intensity of the corner is sharpened, and the depression of the corner of the region 1 is suppressed. Further, in this case, the pattern of any shape can be used instead of the pattern having the recess 7d, and a mask having a dummy pattern independent of a main pattern 7a may be used.

Abstract: PURPOSE:To simplify the constitution of a position detecting device and to reduce its position detection error by controlling the quantity of light emission of a light emitting element that the quantity of photodetection of a semiconductor position detecting element is constant. CONSTITUTION:An objective 5 is fitted to a supporting member 10 and bobbins 13 and 14 wound with movable coils 11 and 12 are fixed to both surfaces of the supporting member. One-side arms of magnets 15 and 16 are surrounded with the bobbins 13 and 14. Further, a light shielding plate 18 in which an aperture 17 is bored is fitted on one surface of the member 10. A light emitting diode 19 and the semiconductor position detecting element 20 are arrange across it. When currents are flowed through the coils 11 and 12, the member 10moves in a tracking direction A with magnetic force produced between the magnets 15 and 16. Then, the light shielding plate 18 moves to shift the aperture 17 in position and the direction of luminous flux from the diode 19 changes. A light spot on the element 20, therefore, shift in position, so the direction and extent of movement of the lens 5 are detected fro the output of the element 20.

Title: Ionization device
Inventor: SHIMOMURA MANABU
IPC: H01J27/08
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To enable a degree of contamination in an ionization chamber to be detected externally. SOLUTION: A repeller electrode 7 is fixed in an ionization chamber 1 by a retaining member made of an insulating material having a surface exposed into the ionization chamber 1. When the interior of the ionization chamber 1 is not contaminated, resistance R2 possessed by the retaining member is substantially infinite and therefore no current flows through resistance R1 except for the time period of ionization. When the interior of the ionization chamber 1 is contaminated, the resistance R2 decreases and current flows through the resistance R1, and therefore an output of a current detecting part 11 is increased. Contamination within the ionization chamber 1 is thereby recognized and cleaning can be carried out timely.
