Title: Production of composite magnetic head
Inventor: HAYAKAWA MASATOSHI
IPC: G11B5/23
Filed: 1987-07-28
Abstract: PURPOSE:To prevent the reaction with bonding glass and to produce a composite magnetic head having high reliability and excellent efficiency by adopting an oxidation atmosphere for a sputtering atmosphere at the time of forming thin Fe-Ga-Si alloy films. CONSTITUTION:The composite magnetic head is produced by a stage for forming the thin Fe-Ga-Si alloy films 3 by sputtering on magnetic oxide substrates 1 machined with the grooves for controlling a track width and a stage for butting the thin Fe-Ga-Si alloy films 3 to each other via a gap spacer and joining and integrating the same by bonding glass 5. Gaseous oxygen is incorporated into the sputtering atmosphere at the time of forming the thin Fe-Ga-Si alloy films 3 at this time to introduce oxygen to at least part of the thin Fe-Ga-Si alloy films 3 near the joint boundary face with the bonding glass 5. The reduction power possessed by the thin alloy films is thereby decreased and the reaction with the glass is prevented. The need for providing antireaction films in particular is thus eliminated and the composite magnetic head having the high reliability and high efficiency is thereby constituted.

Title: Temperature sensor using optical fiber
Inventor: SHIODA TAKAO
IPC: G01K1/02
Filed: 1984-09-10
Abstract: PURPOSE:To measure temperature accurately, by providing an optical fiber, which is provided with a sensor part having a reflecting film with temperature dependence, and an optical fiber, which is provided with a reference part having a reflecting film without temperature dependence, whose characteristics are the same as those of said optical fiber, in parallel, and comparing the reflecting levels. CONSTITUTION:Two optical fibers 1 and 11 have the same characteristics. Short optical fibers 2, 3 and 4 are connected to, e.g., three positions of the fiber 1 in the longitudinal direction through couplers. Reflecting films A, B and C having temperature dependence are provided at the tips of said fibers 2, 3 and 4 by using CaAs and the like. Short optical fibers 22, 33 and 44, which have reflecting films (a), (b) and (c) but do not have temperature dependence, are connected to the other fiber 11, and a reference part is obtained. Both fibers 1 and 11 are arranged in close proximity in parallel, and a temperature sensor is obtained. Light from one optical pulse generator 5 is inputted to the fibers 1 and 11 through a wave splitter 8 and directional couplers 6 and 66. The levels of the backward reflected light beams are measured by optical pulse testers 7 and 77 and compared. For example, even if temperature change occurs in the vicinity of a point D in the fiber 1, the temperatures at B and C can be accurately measured without the effect of said temperature change.

Title: Reciprocating body drive unit in machine tool
Inventor: HIRATA TADASHI
IPC: F16H25/20
Filed: 1990-07-18
Abstract: PURPOSE:To make a large change in the moving speed of an operating body by appropriately controlling a first driving motor for rotating a first nut member screwed with a rod member, and a second driving motor for rotating a second nut member engaged with a spline groove. CONSTITUTION:When a first driving motor 5 is stopped to hold a first nut member 17 in the fixed state and a second nut member 19 is appropriately rotated by a second driving motor 7, a rod member 9 is rotated simultaneously. An operating body 1 is thereby moved crosswise at comparatively high speed through the first nut member 17 and a nut supporting housing 21. Inversely, when the first driving motor 5 is driven to rotate the first nut member 17 at the time of the second driving motor 7 being held in the stop state to place the second nut member 19 in the stop state, the rotation of the first nut member 17 becomes extremely low by the decelerating mechanism formed of a worm 25 and a worm gear 23, in comparison with the case of the second nut member 19. The operating body 1 is therefore reciprocated crosswise at low speed.

Title: Production of magneto-optical recording medium
Inventor: IWANAGA RYUICHI
IPC: G11B11/10
Filed: 1986-08-13
Abstract: PURPOSE:To eliminate a laborious operation such as line erasing by directing the magnetization directions of all magnetic layers to the direction of an erasing state and producing magneto-optical media prior to sticking of substrates with the magnetic layers to each other. CONSTITUTION:After an adhesive agent 2 is coated by a coating roller 4 on the surface of the substrate 6 with the magnetic layer, the magnetization direction of the magnetic layer of the substrate 6 is unified in the direction of the erasing state by a magnetic field generator 1. A magnetic field is also impressed to another sheet of the substrate with the magnetic layer to unify the magnetization direction of the magnetic layer thereof. The magneto-optical recording medium is obtd. by positioning and sticking the two substrates to each other. The remaining of the unerased parts in the magnetic layers is then obviated and in addition, the magnetization directions of the magnetic layers prior to recording are constant even if the medium is set in any position.

Title: Treatment for prolonging life of cut flower
Inventor: OSHITA SEIICHI
IPC: A01N3/02
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for treating cut flowers, capable of prolonging a retention period of freshness after returning to a natural state. SOLUTION: This treatment is performed by inserting a cut flower 2 into an autoclave 1, further inserting water therein from a valve 19, jetting xenon gas into the autoclave by opening a valve 14 form xenon bomb 5 through an inner tube 13 while bringing the xenon gas into contact with the water, dissolving the xenon gas in the water by increasing the partial pressure of the xenon gas in the autoclave, allowing the cut flower to absorb the water from a cut part for about 20hr. The xenon gas after treating is recovered by recovering device 6. The freshness of the cut flower is kept for a long time even in a natural state after the treatment by the simple treatment in a short period. No bad effect on the environment is caused thereby. Moreover, the nonpolar gas can be repeatedly used and thereby the treatment for prolonging a life of a cut flower can be performed practically and economically.

Title: Color liquid crystal panel
Inventor: HIRAISHI HISATO
IPC: G09F9/00
Filed: 1986-08-12
Abstract: PURPOSE:To contrive to improve picture quality, reliability, and economy by constituting a substrate by forming an inorganic transparent film directly or an inorganic transparent film and forming a transparent electrode on the inorganic transparent film, and using this substrate as one element. CONSTITUTION:The organic transparent thin film 51 is formed covering the color filter 23 and further the inorganic transparent thin film 52 is formed covering the inorganic transparent thin film 51. Here, the organic transparent thin film 51 while flattening the irregularity of the surface of the color filter 23 increases the strength of the color filter 23. The organic transparent thin film 51 serves as a barrier for preventing principally ionic impurities that the color filter 23 contains from flowing out to a liquid crystal layer. Consequently, there is no color mixing when viewed slantingly and a rise in liquid crystal driving voltage which causes the problem of upper filter structure and a decrease in picture quality are precluded.
