Title: Superconducting magnet for producing magnetic field in nuclear magnetic resonance system
Inventor: KIDA ATSUSHI
IPC: H01F6/00
Filed: 1991-06-05
Abstract: PURPOSE:To provide a superconducting magnet, for producing a magnetic field, employed in a nuclear magnetic resonance system which is capable of regulating the current of a superconducting shield coil independently of a superconducting main coil so that magnetic field leakage can be reduced. CONSTITUTION:A superconducting magnet, for producing a magnetic field, used in a nuclear magnetic resonance system is designed to prevent magnetic field leakage from a solenoid type superconducting main coil 1 by the addition of a superconducting shield coil 2 in line with the main coil 1. Provided to the shield coil 2 is a switch 5 which can be turned ON and OFF independently of the circuits of the main coil 1. During the setting of the current of the main coil 1, the current of the shield coil 2 is regulated by the control of an operation timing of the switch 5 so that dipole moments of the shield coil 2 and the main coil 1 can cancel each other, thereby reducing magnetic field leakage.

IPC: B29C71/00
Filed: 1980-09-29
Abstract: PURPOSE:To obtain a highly uniformly film of which various physical properties are balanced in a longitudinal and traverse directions by forcedly advancing the film in such a condition that only central narrow part of the longitudinally and traversely oriented film is gripped by nip rolls while both side ends of said film is gripped. CONSTITUTION:In preparing a biaxially oriented film by a method wherein a thermoplastic polyester film (e.g.; a polyethylene terephthalate film or the like) uniaxially oriented to a longitudinal direction is oriented to a traverse direction by a tenter and, further, subjected to heat treatment, while both sides ends of the film after traverse orientation is completed are gripped by a gripping means of the tenter, only a narrow part in the vicinity of a central part of the film is gripped by nip rollers to impart advancement drive action to said central part of the film and, thereby, a process so as to forcedly advance said central part is added. By adding said process, bowing phenomenon can be eliminated (or reduced) and the biaxially oriented polyester film with uniform physical properties is obtained.

Title: Magnetic recording medium
Inventor: CHIBA KAZUNOBU
IPC: C09D131/04
Filed: 1984-06-29
Abstract: PURPOSE:To obtain a thin ferromagnetic metallic film type magnetic recording medium which is free from curling by coating an emulsion having a specific glass transition point or below on a non-magnetic substrate and forming a thin ferromagnetic metallic film on the continuous film. CONSTITUTION:The uniform continuous film can be formed by coating the emulsion having <=30 deg.C glass transition point on the non-magnetic subsrate. Since the continuous film is softer than the magnetic layer and non-magnetic substrate, said film disperses the stress concentration and relieves the stress to be generated between the magnetic layer and the non-magnetic substrate. The magnetic recording medium which is free from curling is thus obtd. For example, a polyvinyl acetate emulsion, etc. are used for the emulsion. The non-magnetic substrate is exemplified by plastics including polyester such as polyethylene terephthalate and polyamide imide. The thin ferromagnetic metallic film material is exemplified by metals or alloys such as Fe, Co and Ni or the metals or alloys incorporated therein with metals such as Cr and Al. The means for depositing the thin ferromagnetic metallic film material is exemplified by a vacuum deposition method, ion plating method, sputtering method, etc.

Abstract: PURPOSE:To obtain an inserting or discharging device which facilitates fitting operation, has high airtightness, and moves a longitudinal body smoothly by composing the device of a cylindrical body, a receiving member, a sealing mem ber, a pressing member, and a cap nut. CONSTITUTION:The receiving member 17, sealing member 18, and pressing member 19 are inserted into the cylindrical body 16 into which the longitudinal body is inserted, and the nut cap 20 is engaged threadably with the cylinder body 16.

Title: Pneumatic tire
Inventor: NISHIKAWA HIROAKI
IPC: B60C11/00
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To improve sideways sliding performance at the time of cornering on an icy road or a wet road. SOLUTION: When a sideways force is applied to a tire when cornering, an adhesion area becomes larger on a shoulder side of the tire than on the equator side. Therefore, if the density of elongated independent bubbles 24 of a tread 12 is made higher on the shoulder side of both sides in the direction of the width of the tire than on the equator side of the tire, water on the shoulder side can be easily discharged to increase frictional force when cornering even if the edging force of the grooves and sipes of the tire is small. This improves cornering performance on an icy road or a wet road.

Title: Magnetic control type switching regulator
Inventor: ONDA KENICHI
IPC: H02M3/28
Filed: 1983-07-27
Abstract: PURPOSE:To increase the control range by reducing the rate of change of time of a voltage induced between the secondary winding terminals of a transformer when a switching element is turned ON and OFF. CONSTITUTION:A capacitor 10 as a voltage suppressor 1 is connected with the secondary side of a main transformer TM. Even if a switching element connected with the primary side of the transformer TM is turned OFF and a voltage is induced at the secondary side of the transformer TM, the voltage charges the capacitor 10. Accordingly, the rate of change of time of the induced voltage decreases. Consequently, the rate of decrease of the current flowed to a diode D1 immediately before the switching element becomes OFF decreases, thereby suppressing the reverse recovery current.

Title: Refining method for aluminum
Inventor: SHINGUU HIDEO
IPC: C22B21/06
Filed: 1980-09-29
Abstract: PURPOSE: To manufacture solidified Al of high purity by agitating the liq. phase of molten Al by Lorentz's force in a process for solidifying the molten Al so as to move impurities away from the solidification interface and to prevent the growth of dendrite at the interface.  
     CONSTITUTION: When molten Al 6 in a crucible 5 is cooled by a chill 2 from the underside, it begins to solidify from the underside. A nucleus is first produced on the bottom of a crucible 5, and a smooth solidification interface 11 is formed at once. By supplying a DC current to a coil 9 for generating a magnetic field from a power source 10 and electrifying the molten Al 6 with a power source 8 through an electrode 7, the Al 6 is vigorously fluidized in one direction by Lorenzt's force. As a result, the whole liq. phase is agitated, and impurities discharged into the liq. phase from the interface 11 or concd. on the interface 11 are moved away from the interface 11 and dispersed in the whole liq. phase. Accordingly, no dendrite is produced, and solidification proceeds while maintaining the smooth interface 11 at all times. When a prescribed amount of Al is solidified, the power supply to the coil 9 and the electrode 7 is stopped.

IPC: B01D63/00
Filed: 1990-05-25
Abstract: PURPOSE:To secure excellent transmission capacity by uniformly loading the whole of a bundle like hollow yarn membrane with a raw solution, in a hollow yarn membrane module used in solid-liquid separation, by interposing a spacer dividing the hollow yarn membrane bundles in a cylindrical case into a plurality of groups within the hollow yarn membrane bundles. CONSTITUTION:Hollow yarn membranes each usually having an outer diameter of 2.0-0.5mmphi are received in a cylindrical case 1 having a raw solution inflow port 11 in a bundled form. One ends (a) of the respective hollow yarn membranes pierce the partition wall 3 provided to one end of the case 1 to open to the upper surface of the partition wall and the other ends (b) thereof are closed. A spacer 4 having a cruciform section is interposed within the hollow yarn membrane bundles 2 to divide the hollow yarn membrane bundles 2 into four groups 21, 22, 23. Even when the respective yarn membranes are ready to bend and deform by the lateral component of the flow of a raw solution, the cross-sectional area of the yarn membrane groups can be sufficiently reduced because the yarn membrane groups are divided by the spacer 4 and, therefore, even when the yarn membrane groups are increased in density, the load of all of the hollow yarn membranes can be almost uniformized, and excellent transmission water quantity can be ensured. Further, the collective accumulation and adhesion of a solid can well, be prevented and the contamination of membranes can be suppressed, and the washing thereof is also easy.
