Title: Thin film magnetic sensor
Inventor: NAKAMICHI MASUMI
IPC: G01R33/06
Filed: 1988-10-07
Abstract: PURPOSE:To maintain characteristics which are stable for a long time even in a high-temperature atmosphere by interposing an oxide film or nitride film of silicon or aluminum between a substrate and a magnetic material thin film. CONSTITUTION:This element is formed by forming the oxide silicon film 5 on the glass substrate 1' by sputtering and also forming the magnetic material thin film 2' thereupon in a thin line pattern by resistance heat vapor deposition. Further, a rectangular electrode 3' is soldered to part of the thin film 2' and the whole body is coated with a protection film 4' except on the surface of the electrode 3'. The oxide film or nitride film of silicon or aluminum formed between the thin film 2' and substrate 1' operates as a diffusion preventing film which prevents alkali metal elements present in the substrate 1' from being diffused or moving the thin film 2' without checking the thin film 2'.

IPC: C04B40/00
Filed: 1989-09-29
Abstract: PURPOSE:To make it possible to economically manufacture homogenous building material by a method wherein diatomaceous earth lump is shaved in scales and, after that, granulated or rolled so as to be mixed with Portland cement and/or lime, fiber and extrusion assistant, watered for water content control, and, after that, kneaded, extruded and formed and finally steam-cured under atmospheric pressure. CONSTITUTION:Diatomaceous earth lump in humid state as is dug is shaved in scales and, after that, granulated in granules having the diameter of 6mm or less or rolled with rolls down to the thickness of 4mm or less so as to be mixed with Portland cement and/or lime, fiber and extrusion assistant, watered for water content control and, after that, kneaded, extruded and finally steam- cured under atmospheric pressure.

Title: Sound absorption structure
Inventor: TOMIMASU KAZUHIRO
IPC: F04B39/00
Filed: 1990-09-25
Abstract: PURPOSE:To obtain an inexpensive sound absorption structure without much man-hour by inserting a bag-like inserter in which sound absorption substance consisting of liquid- and powder-like fluid is filled in spaces between the wall of a machine room and apparatuses which are installed in the room. CONSTITUTION:A bag-like inserter 6 which is deformed freely is inserted in a space between the wall of a compressor chamber 10, and a compressor 2 and/or piping 4. A sound absorption substance 7 which consists of liquid- and powder-like fluid is filled in the bag-like inserter 6. Since the space is almost fully filled with the sound absorption substance, sound absorption power in the compressor chamber 10 is improved to prevent resonance. As the sound absorption substance 7 makes contact with apparatuses such as the compressor 2, piping 4, and a control box 5 via the bag-like inserter 6, damping action occurs. Consequently, it is possible to realize an inexpensive sound absorption structure because sound absorption work does not consume so much man-hour.

Title: Video equipment
Inventor: NISHIJIMA TAKEO
IPC: H04N19/00
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To provide the video equipment in which analysis of a recording image on the occurrence of an error is facilitated by eliminating an unrecorded field or frame. SOLUTION: The video equipment 1 uses a video image reduction/synthesis processing section 3 to synthesize video images by nframe stored in each area as one frame video image. The synthesized video signal is compressed by a video processing/compression section 4 and the compressed data are recorded in a data recording section 5. A control section 6 controls a recording speed control section 7 so as to set the speed to 1/n of the speed at the usual recording based on setting by a key entry section 8 and on results of detection by sensors 1 to n. Thus, the tape is operated at a drive speed that is 1/n of the usual speed and the received video signal realizes a recording time of multiple of (n) without losing field or frame information.

Abstract: PROBLEM TO BE SOLVED: To quickly and perfectly execute the exchange of a degassing vessel by forming the separating direction of the vacuum degassing vessel with a gas exhaust duct to almost a tube axial direction of the gas exhaust duct. SOLUTION: To skull, the action of shearing direction is not received but the force of tension direction is loaded by separating a duct connecting tube 3 and a gas exhaust duct 1 along the tube axial direction. Therefore, the detachment between the skull stuck on the tube inner surface and the tube inner wall, is developed and the separation can be executed in comparatively easy way. For this purpose, the shifting direction of the vacuum degassing vessel 2 is made to shift and retract along the separating direction of the connecting part C of the duct.  That is, the shifted vacuum degassing vessel 2a is separated in the tube axial direction of the gas exhaust duct 1, and after straightly retracting as it is, this vessel is exchanged with the other vacuum degassing vessel 2b under waiting in the retracting line of the cross rails 6 and simultaneously retracted as the retracted vacuum degassing vessel 2c.

Title: Continuous manufacture of glass fiber reinforced laminated plate for electrical use
Inventor: ISSHIKI MINORU
IPC: B32B17/04
Filed: 1987-10-09
Abstract: PURPOSE:To improve the thicknesswise dimensional stability as well as the through-hole reliability, by specifying the time to laminate after impregnation of setting resin liquid into the glass non-woven fabric. CONSTITUTION:Glass cloth is arranged on both outside, and a glass non-woven fabric insite, which are impregnated with setting resin liquid. The time from impregnation of setting resin liquid to laminate is specified as 120 sec. or more, and an impregnating base material is carried and jointed, and the time to laminate a cover sheet and/or metal foil is specified as 5-120 sec. Since the impregnability and retainability of setting resin are affected by the viscosity of resin liquid and the basis weight of the glass non-woven fabric, the setting resin does not contain flux, and sets without generating volatile by-product. The viscosity is 0.1-15 poise at room temperature; likewise, the glass paper and glass mat of the glass non-woven fabric both have basis weight 10-200g/m<2>. The inorganic filler added to the setting resin is 50 times or less in weight.

Title: Lighting optical system
Inventor: KONO MICHIO
IPC: G03F1/00
Filed: 1985-11-14
Abstract: PURPOSE:To light an arcuate surface to be irradiated uniformly, to obtain the same effective light-source image at all points in an irradiation region and to attain a high illumination effect by arranging a luminous-flux transmission member having a predetermined shape to one part of a lighting optical system. CONSTITUTION:A light source 15 and the plane of incidence of a luminous-flux transmission member 17 are arranged positioned near two focal points of an elliptical mirror 16. The plane of incidence of the luminous-flux transmission member 17 takes a circle or a rectangle or the like, and the shape of the plane P1 of projection is formed to an arcuate shape. Outgoing luminous flux from the luminous-flux transmission member 17 is changed into parallel luminous flux by a first optical system 18, and projected to a light integrator 19. The plane P1 of projection of the luminous-flux transmission member 17 and the plane P2 of projection of the light integrator 19 are made approximately conjugate. Since the plane P1 of projection is formed to the arcuate shape, luminous flux on the plane P2 of projection as the conjugate plane of the plane P1 of projection is formed to the arcuate shape, thus reducing the eclipse of luminous flux. A slit for an arcuate opening on a slit opening plate 21 is formed onto a mask M by an optical system 22. Accordingly, the upper section of the mask M can be lit efficiently and uniformly.
