Title: Manufacturing method of copper rod by rolling
Inventor: DARERU DABURIYU BUREITORINGU
IPC: B21B27/10
Filed: 1990-03-30
Abstract: PURPOSE: To improve copper rod quality, roll life and performance by controlling an oil-water emulsion used for cooling and lubricating rolls by using a conductivity probe. CONSTITUTION: The production of a copper rod by rolling copper may be improved by effectively controlling the water-soluble emulsion used for lubricating the rolls by using the conductivity probe for maintaining the conductivity of the emulsion within a desired operation limit. The conductivity measurement is substantially unaffected by the pollutant accumulating in the emulsion under process conditions or at the time of rolling operation and the maintenance of the conductivity only within the set limit increases the effectiveness of using the water-soluble oil, thereby creating the enhanced efficient and cost effective rolling operation. A sample is periodically sampled from the emulsion and the conductivity thereof may be easily measured by a conductivity meter. Since the lesser replenishing oil is used, the saving of a cost and the improvement in the roll life are possible.

Title: Horizontal deflection output circuit and method therefor
Inventor: SATO SHINYA
IPC: H04N3/23
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To continuously correct raster distortion at low cost by controlling a winding current of a coil placed for cancelling a magnetic field of a horizontal linearity coil, so as to control an inductance of the horizontal linearly coil thereby improving the horizontal linearity on a screen. SOLUTION: A horizontal operating frequency of an FH-V conversion circuit is digitized, based on a horizontal synchronizing signal received by a receiver. A variable linearity control circuit provides an output of a control signal, to provide optimum linearity to a variable linearity coil drive circuit, based on an FH-V voltage and a SIZE signal controlling a horizontal deflection size. The inductance of variable linearity coils L1, L2 inserted in series with a horizontal deflection coil LY is changed by canceling the magnetic flux to improve the distortion of a horizontal deflection current. The variable linearity coils L1, L2 are inserted to a horizontal output circuit, so that their saturation characteristics have polarities opposite to each other.

Title: Reversible solid state contactor
Inventor: SUZUKI YUKIO
IPC: H02P23/04
Filed: 1989-04-05
Abstract: PURPOSE:To commonly use a trouble detector for normal and reverse rotations and to provide economy and small size by incorporating the detector only in one SSC(solid state contactor), and providing a thermal for locking the function of the detector by other SSC drive input signal. CONSTITUTION:When a normal rotation signal is input to input terminals 1a, 1c and the signal is not input to a terminal 1b, a photodetector 11b is conducted by a light emitted from a light emitting unit 11a, and a capacitor 17 is charged. Accordingly, the output of a NOR element 21 goes to an H level, and a NOR element 22 goes to an L level. A transistor Tr 15 is interrupted, a Tr 16 is conducted, a normal rotation SSC is conducted, and a reverse rotation SSC is interrupted. In this case, a light emitting unit 14a is conducted thereby conducting a light emitting unit 14b. The Tr 15 is not conducted even if the output of a NOR element 29 goes to an H level due to an erroneous operation.

Title: Microphone traverser for acoustic holography
Inventor: MIYAKI KATSUMI
IPC: G03H3/00
Filed: 1980-06-23
Abstract: PURPOSE:To control, for better balance, the position of a traverser used to hold a moving microphone by using a balance weight. CONSTITUTION:A balance weight 16 having weight equivalent to the total  weight of a moving microphone 2 and a traverser 10 is arranged in a hollow 8b formed within a support 8a. A toothed wheel 20 rotates when the step-motor of a driving gear 11 is driven, causing chains 18, 19 and then the traverser 10 and the balance weight 16 to move. Since the positions of the traverser 10 and the balance weight 16 have been so arranged that the positions are allowed to branch away to the left and right with the toothed wheels 12, 20 as boundaries, this keeps the balance between downward force generated by the moving microphone 2 and the traverser 10, and downward force caused by the balance weight 16.

Title: Resolver using pulse encoder
Inventor: TANAKA TADASHI
IPC: G05D3/12
Filed: 1986-04-15
Abstract: PURPOSE:To convert variation in angle of rotation into an electric phase angle which varies continuously as an analog value by further adding and subtracting a signal obtained by multiplying a two-phase sine wave signal by the other two-phase sine wave signal. CONSTITUTION:A pulse encoder 1 outputs two-phase since wave signals ea and eb whose frequency is P cycles according to 360 deg. variation in angle of mechanical rotation or movement quantity theta. Those signals are multiplied by two-phase sine wave signals efa and efb from a two-phase since wave oscillator 2c through multipliers 3 and 4 respectively to generate signals ex and ey, so that an adder and subtracter 5 outputs a sine wave signal ec having a phase shift thetae(=P.theta) varying continuously on the basis of the phases of the signals efa and efb. Consequently, the angle of rotation or rotating speed of a body of rotation, or the movement quantity of a moving body is detected with high accuracy based on a continuous relatively-large phase shift quantity that the phase shift thetae has.

Abstract: PURPOSE:To enable the exclusive separation and recovery of normal whiskers in high efficiency with dry process, by loosening entangled whiskers in a tank with a fluidizing air stream, proceeding the loosening by disturbing a transportation flow during pneumatic transportation and classifying and recovering the whiskers. CONSTITUTION:A whisker raw material supplied to a tank 1 through a feed port 2 forms a filled layer 5 on the upper face of a fluidized bed 3. A fluidizing air flow is blasted from an air flow supplying means 4 against the filled layer. The layer 5 begins to flow and the whiskers are agitated in the tank 1. Blown up whiskers are introduced together with air stream into a pneumatic transportation means 7 connected to an exhaust port 6 and large lump of blown up whisker is sedimented and returned to the layer 5 by gravitational force. Fibers entangled by fusion, etc., are loosened by blowing a stirring flow through an air flow blasting means 9 of a flow-agitation means 8 attached to the middle part of the means 7. The flow rate of the stirring flow is 1-5 times the flow rate of the transportation flow of the means 4. If necessary, the flow rate is increased by a nozzle apparatus 10 to loosen the fibers and to cut and recover the pill-like abnormal surface fibers and the fibers are classified with an air gyration classifier 11.

Title: Magnetoresistive sensor for sensing magnetic field
Inventor: SHIMIZU YUTAKA
IPC: H01L43/08
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To obtain a differential magnetoresistive sensor by providing a first spin valve, having means for detecting a change of electric resistance caused by the difference of rotation of a ferromagnetic material in an external magnetic field, a second spin valve by which magnetized direction of a third ferromagnetic layer and a magnetized direction of a fourth ferromagnetic layer are orthogonal to each other when an applied magnetic field is zero, and detection means. SOLUTION: When a vertical signal magnetic field enters from a magnetic recording medium 10, the magnetized directions of magnetic films 4 and 4' rotate within the surfaces of the magnetic films 4 and 4' in accordance with the direction of the signal magnetic field. If the magnetic field is upward, within the surface of the magnetic film 4', the magnetized direction rotates so as to be closer to a direction opposite to a direction M4, and the resistance of a spin valve 2 becomes lower, while the resistance of a spin valve 3 becomes higher. If the magnetic field is downward, in the surface of the magnetic film 4', the magnetized direction rotates so as to be closer to the direction M4, and the resistance of the spin valve 2 becomes higher, while the resistance of the spin valve 3 becomes lower. Thus, in the magnetic resistive sensor, the changes of electric resistance with respect to the same signal magnetic field are symmetrical, and output signals are detected from the spin valves 2 and 3.
