Title: Superconductor
Inventor: ONO MICHITAKA
IPC: H01B12/08
Filed: 1989-06-15
Abstract: PURPOSE:To obtain an AC superconductor of good performance by using a glass fiber reinforced resin plate as a mandrel. CONSTITUTION:As a mandrel 2 of a conductor, a glass fiber reinforced plastic(FRP) is used. A superconductor is formed by stranding a strand 1 of AC superconducting wire around the mandrel of the FRP plate 2. When a coil is manufactured using the conductor, the movement of the conductor due to electromagnetic force is suppressed by the FRP plate 2 whose mechanical strength is high, while an eddy current due to AC excitation does not occur. A conductor of high mechanical strength whose eddy current loss is little, can thus be obtained.

Title: Magnetic head positioning system
Inventor: HASHIMOTO TOSHIKAZU
IPC: G11B21/10
Filed: 1987-06-16
Abstract: PURPOSE:To improve the reliability of recording/reproduction of data information by applying positioning tracing from the tracing quantity with respect to a track and the direction of track tracing by a magnetic head based on distortion information when the magnetic head cannot rad servo information of a specific sector. CONSTITUTION:The magnetic head 9 is positioned to a servo track-1 prior to the recording or reproduction of initial data information, the servo information is read to obtain information relating to the distortion of a medium. When the medium is deformed, since the direction and quantity of distortion at a position recorded with the servo information is obtained by reading out each servo information of the track, it is used as the distortion information. When the deformed quantity of the medium is small, positioning tracing is applied by using a position error signal from the readout servo information. On the other hand, when the deformation of the medium is large and no servo information can be read from a sector, it is corrected by using the distortion information from a servo track stored in advance. That is, the moving direction for position tracing of the magnetic head is determined by the information of distortion direction and the moving quantity is determined from the distortion quantity.

IPC: H01J9/24
Filed: 1981-09-25
Abstract: PURPOSE:To readily realize a bulb which needs neither a lamp base nor a tip-off  part- protecting cover, by positioning a tip-off pointed end inside the external  face of a stem base in the production of the bulb with a button stem base. CONSTITUTION:A tip-off pointed end 2 projects outside further than a base plane 7, in case of carrying out a tip-off process of an exhaust pipe 5 using a button stem 3. Next, the tip-off pointed end 2 which projects outside further than the base plane 7 is heated, softened, pressed by an outside actuater 10, and shaped in order to be received in a recess 9. Said tio-off pointed end is shaped as shown by a mark 2' in the figure, positioned in the pipe inside further than the base external plane 7; since projected part thereof is entirely removed, the posibility of breakdown at the tip-off pointed end can be completely cancelled during a treatment of a fluorescent lamp in which the button stem is sealed.

Title: Hydraulic rolling reduction type pinch roll
Inventor: ABO AKIRA
IPC: B21B37/62
Filed: 1982-09-01
Abstract: PURPOSE:To prevent a strip material from a partial rolling reduction, by automatically controlling the drawing-down forces at the left and right sides of pinch rolls basing on the detected value of the relative position of the pinch rolls and the material. CONSTITUTION:A strip material 4 is subjected to rolling reduction while holding it between a rolling reduction roll 1 and a fixed roll 2 by moving vertically the roll 1 with the action of hydraulic cylinders 5. A potensiometer 16 detects the distance (a) between the end face of the material 4 and the roll 1, and basing on he distance (a), a pressurereducing-valve controlling-command unit 13 calculates the hydraulic pressures P1, P2 of respective cylinders 5 necessary for performing a parallel rolling reduction of the material 4 by the roll 1. And electric signals equivalent to the hydraulic pressures P1, P2 are converted into electric currents (i1), (i2) corresponding to the signals by pressure-reducing-valve controlling units 11, 12, and the currents (i1), (i2) are inputted to motordriven pressure-reducing valves 9, 10 to make the outputs of both sides cylinders 5 to be P1, P2 by the valves 9, 10. Thus, regardlessly the material width, the material 4 is prevented from a partial rolling reduction by the roll 1.

Abstract: PURPOSE:To provide a fluid supply coupler capable of high pressure supply of fluid regardless of the kind of the supply fluid, with no limitation in the number of rotation and not generating oscillation, heat, etc. CONSTITUTION:Fluid flowed out to a fluid resistance passage 23 partitioned between an outer end surface of a coupler shaft 9 and a recessed part side surface of a coupler main body 15 flows into a pump house 27 partitioned between a dynamic pressure generating groove 25 formed on the peripheral side surface of the coupler shaft 9 and a recessed part side surface of the coupler main body 15 after decompressed in the fluid resistance passage 23. The greater part of the fluid leaked out is returned to the fluid resistance passage 23 by pumping work of the pump house 27, and a part of it is leaked out to a leaked out fluid pressure dropping chamber 31. As the outside of the coupler main body 15 and the leaked out fluid pressure dropping chamber 31 are sealed by a fine clearance 41 to which compressed air is supplied, the leaked out fluid is discharged outside from a drainhole 33.

Title: Controlling method for bypass mixing
Inventor: FUKUI HIDEKAZU
IPC: F24H1/10
Filed: 1991-05-28
Abstract: PURPOSE:To improve the efficiency with which an apparatus resumes the supply of hot water by providing a bypass equipped with a bypass water-flow control valve which detours a heat exchanger and connects an inflow channel for cold water and an outflow channel for hot water in a setup to shut off said bypass water-flow control valve completely when the apparatus is on standby and the difference between the temperature of the hot outflow and that of the cold inflow is less than a specified value. CONSTITUTION:A hot water-supplying apparatus 1 has its heat exchanger 2 heated by a burner 3. The inlet to the heat exchanger 2 communicates with a water suction channel 20 by an intake channel 21 for the connection and the outlet is connected with a hot outflow channel 22. A bypass 23 provided with a bypass water-flow control valve 61 branches off from the water suction channel 20 and is connected to a cold water-hot water stirrer 10. When the apparatus is on standby and the difference between the temperature of the hot outflow and that of the cold inflow is less than a specified value, the bypass water-flow control valve 61 is shut off completely. This method, when the supply of hot water is resumed, prevents the mixed hot outflow from dropping in temperature and enables the apparatus to quickly increase the temperature of the mixed hot outflow.

Title: Semiconductor optical amplification element
Inventor: FUKUNAGA TOSHIAKI
IPC: H01S3/10
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To control a horizontal mode to a fundamental horizontal mode even on high output by forming irregularities on a side end surface along the waveguide direction of a tapered part for entrapping light that enters from a beam incidence port and is waveguided. SOLUTION: When a laser beam being subjected to a fundamental single mode oscillation enters a beam incidence port 3, the beam guides a beam waveguide 6, is amplified to the laser beam with high output while a single horizontal mode is being maintained in the beam waveguide 6 being subjected to current injection and a beam amplification region 1 being widened toward the end, and is emitted from a beam emission port 4 to the outside of an element. At the element, fine irregularities 16a are formed on a side end face along the beam waveguide direction of the tapered part of a cladding layer 16, and a return beam from an element end face where the beam emission port 4 is provided reaches the side end face of the cladding layer and is scattered and lost.  Also, when beams that enter the element from an area other than the beam incidence port 3 reach the recessed and projecting parts 16a, they scatter, thus preventing a fundamental horizontal mode from being disturbed and generating a diffraction limitation beam up to a high output region.
