Inventor: SHINOZAKI TAKASHI
IPC: H01F13/00
Filed: 1994-03-14
Abstract: PURPOSE:To provide a magnetization medium, a magnetic head for magnetization to obtain the magnetization medium, a magnetization method and a magnetizer which allows the obtaining of an effective output even when the linearity of a magnetizing surface deviates to an extent depending on the state of magnetization or fixing of the magnetization medium or an angle at which the magnetizing surface of the magnetization medium is opposed to an MR head is not in adjustment. CONSTITUTION:A groove 131a is formed at a magnetic gap G part on the tip face of a magnetic core 131 of a magnetic head 13 for magnetization with the shape of a cross section thereof presenting almost a circular arc corresponding to a lower half portion of a circle on the outer circumference of a magnetization medium 2. The part of the groove 131a is pressed onto the outer circumferential surface of the magnetization medium 2 and the head 13 is energized electrically in the opposite direction alternately moving the magnetization medium 2 by a specified distance relatively in one direction longitudinally to the head 13. This enables the magnetization of the medium 2 at a large angle of magnetization.

Filed: 1990-02-22
Abstract: PURPOSE:To facilitate the increase in the current amplification factor of the lateral type BPT by forming a potential barrier in the interface between an emitter region and a base region. CONSTITUTION:An emitter region ER, a collector region CR and a base region BR are structured in lateral type; a potential barrier working to the minor carriers of the region BR in the depth direction of the region ER is formed in a part of the region ER; while a semiconductor layer 30 having the wider forbidden band width than that of the material of the region ER is formed on the region ER. Accordingly, the potential barrier acts on the minor carriers of the region BR in the depth direction of the region ER to prevent the emitter current from being diffused into a substrate 1 as well as the recombination current in the region BR from decreasing; furthermore, the current component injected into the region ER from the region BR is decreased so that the current amplification factor of the lateral type BPT may be increased.

Title: Optical modulating element
Inventor: SUZUKI MASATOSHI
IPC: G02F1/025
Filed: 1988-02-26
Abstract: PURPOSE:To attain rapid modulation at a low voltage even when the intensity of incident light is >=0.1mW by setting up a difference between incident photon energy and modulation waveguide forbidden band width energy to >=50meV to suppress the deterioration of a modulation voltage and band width due to the increment of incident light intensity and setting up the length of the title element also to a previously fixed length. CONSTITUTION:When incident intensity of incident light into an optical waveguide is >=0.1mW, the forbidden band width energy of the optical waveguide layer is >=50meV and the ratio of energy difference between forbidden band width energy and incident light energy to the length of optical modulating element determined by the length from the incident end face of the optical waveguide up to its projection end face is 10meV/mm-250meV/mm. Consequently, the optical modulating element capable of executing low voltage and rapid modulation almost without generating the increment of the modulation voltage or the reduction of the band width even when the incident light intensity is increased from 0.1mW practical level to several mW or more can be obtained.

Abstract: PURPOSE: To prevent occurrence of flowing of an adhesive into a nozzle. CONSTITUTION: After a cover 6 made of a piezoelectric ceramic is connected to a piezoelectric ceramic plate 2 having a groove formed thereon so as to form an ink chamber 4, an adhesive 70 is transferred to end faces of the piezoelectric ceramic plate 2 and the cover 6 so as to adhere a plate 59 to be worked into a nozzle plate. An etching liquid of the plate 59 is led into the ink chamber 4 so as to act on the plate 59, so that the plate 59 is etched into a shape peculiar to etching i.e., into a tapered shape wherein the cross section decreases to the proceeding direction of the etching liquid by using the shape of the ink chamber 4 as a mask. As a result, steps to be generated in a conventional way do not generate at the joint of the ink chamber 4 and the nozzle plate, so that a smooth nozzle is manufactured from the ink chamber 4.

IPC: F25B47/02
Filed: 1994-03-14
Abstract: PURPOSE:To prevent a problem such as damage, etc., of each air conditioner by controlling a discharge side pressure of a compressor to a predetermined pressure or less when frost adhered to an evaporator is defrosted. CONSTITUTION:When the state that a temperature of an evaporator 11 is 0 deg.C or lower is continued for 60min, fans 14a, 14b are stopped, and solenoid valves 19, 20 are opened. Thus, high temperature and high pressure refrigerant is guided into the evaporator to defrost the evaporator 11. If a discharge side pressure of a compressor 6 becomes a predetermined value or more during the defrosting control, the fans 14a, 14b are driven. Thus, a refrigerant quantity flowing in a refrigerating cycle is reduced to decrease a work amount from the compressor to the refrigerant. As a result, internal energy of the refrigerant is reduced, and the discharge side pressure is suppressed to a predetermined value or less.

Abstract: PROBLEM TO BE SOLVED: To improve weatherability, transparency, and flaw preventing property by forming a layer A having as a main component a benzotriazole monomer copolymer acrylic resin on at least one face of a thermoplastic film and forming a surface hardening layer B having a pencil hardness H or above on the layer A. SOLUTION: For a benzotriazole monomer, a monomer which has a benzotriazole and an unsaturated double bond can be used without particular restriction. However, a 2-(2,-hydroxy 5,-methacryloxy ethyl phenyl)-2H- benzotriazole is preferable. A copolymer is layered on one face of a base material film as an organic solvent or a moisture dispersing body so as to form a layer A. Also, for a surface hardening layer B, the pencil hardness after layering is preferably H or higher. For the surface hardening layer like this, an acrylic, a urethane, a silicone, etc., is used. Thus, a stable layered film having excellent weatherability and flaw resisting property can be obtained.
