Patent JP-H03229084-A (JP)
Title: Flow control valve
Inventor: TAKAHASHI ISATO
IPC: F16K39/02
Filed: 1990-02-01
Abstract: PURPOSE:To make such a valve that is less in the number of part items, lighter in weight and compact in size possible to open or close the valve element so smoothly by forming a pressure chamber, partitioned off from both inlet and outlet passages, in a valve chest formed in these passages, and installing an interconnecting hole, between the inlet passage and the pressure chamber, in the valve element. CONSTITUTION:While a solenoid 18 is excited, a plunger 25 is attracted to this solenoid 18, a valve element 20 is energized to the right, and an inlet passage 12 is opened and interconnected to an outlet passage 13. In addition, when the solenoid 18 is demagnetized, the valve element 20 is energized to the left by a return spring 27, so that the passage 12 is closed by the valve element 20 and interrupted from the passage 13. Accordingly, the valve element 20 opens or closes through excitation and demagnetization of the solenoid 18. Next, if a diameter D2 of a flange part 22 is made larger than a diameter D1 of a seat part 15, force F comes to almost nothing. So that the valve element 20 will not receive longitudinal force any longer. Consequently, the valve element 20 receives no effect of intake negative pressure being guided out of the passage 13, thus stable on-off operation is secured at all times and, what is more, the on-off operation of the valve element 20 is made smoothable.

Title: Line switching device
Inventor: SUZUKI EIJI
IPC: H04B1/74
Filed: 1988-02-03
Abstract: PURPOSE:To attain no hit switching even if the quality of line is deteriorated rapidly by providing a transmission side delay circuit retarding a signal sent to a standby transmission section by a prescribed time and a reception side delay circuit having the same delay time. CONSTITUTION:In the transmission of a 1st signal via a transmission side switching means 4 to a standby transmission section 11, a transmission side delay circuit 43 is provided in the transmission side switching means 4 to give a delay time tau being a hit time equal to the sum of a fault detection time, a forward/return propagation delay time and switching time in addition to a margin time of a prescribed value. A reception side delay circuit 27 to give a delay of a time tau is inserted between an active reception section 23 and a high speed switch 26 accordingly. If a fault is detected at the input side of the reception side delay circuit 27, the high speed switch 26 is driven at a point of time without loss of data retarded in the reception side delay circuit 27 to apply no hit switching. Thus, the line switching is attained by no hit switching even to the deterioration in the line quality due to rapid fading or device fault.

Title: Device sensitive to supersonic energy intensity
Inventor: DEEBITSUTO HAAMAN RAFUAERU BIR
IPC: G02F1/03
Filed: 1977-03-02
Abstract: An interferometer, that simultaneously employs two phase-quadrature reference beams of coherent light which interfere with a signal beam of coherent light reflected from a spot of a displaceable signal mirror insonified by an ultrasonic wave, permits an output signal to be derived which is proportional to the sum of the squares of the ultrasonic frequency component of the interference between the signal beam and each respective one of the reference beams. This output signal is inherently substantially proportional to the intensity of the ultrasonic wave then insonifying the spot of the signal mirror and independent of random phase drift and environmental vibrations in the interferometer. The interferometric technique of the present invention, which permits the ultrasonic wave to be in the form of pulse bursts of only a few cycles so that the output signal can be range-gated, is suitable for use in an ultrasonic-wave measurement and image display system.

Title: Fishing float
Inventor: YOSHIMI YUKIHARU
IPC: A01K93/00
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent the damage, etc., of a member of a cylindrical shape fixed to a float body. SOLUTION: A float 10 (fishing float) is composed of a top 12, a buoyancy body 14 and a threading part 16. The top 12 (member of a cylindrical shape) is constituted of a shape memory alloy (SMA: Shape Memory Alloy) having superelastic functions, the buoyancy body 14 of wood and the threading part 16 of a metal, respectively. These constituent elements are integrated, for example, with an adhesive or by screw-in, etc. The shape memory alloy constituting the top has memory to form a liner shape at least in a water temperature region. Even if the float 10 is thrown together with a fishing line 18, the float is not immediately restored to an original state and is not broken due to the superelastic functions of the shape memory alloy constituting the top 12.  Consequently the float 10 prevents the damage of the top 12 and can surely maintain a role as an index showing the position of a hook 20.

Title: Defect detecting method of surface of article
Inventor: NAKAYAMA MINEO
IPC: G01N21/89
Filed: 1984-02-14
Abstract: PURPOSE:To detect the defect of the surface of a material to be checked sensitively, by using light in the region of ultraviolet-ray wavelength, in which the material to be checked becomes opaque for the light beam, and providing a wavelength selecting filter on the light projecting side or on the light receiving side as required. CONSTITUTION:An incident light beam from an ultraviolet-ray laser tube 5 is projected and scanned on a material to be checked 1 through a collimator 6 and a rotary mirror 7. The reflected scattered light from a defect 2 on the material to be checked is extracted by a converging fiber band 9 and detected by a photoelectric multiplier tube 8. A wavelength selecting filter 12 cuts the visible light in the scatterend light, which is taken out of the converging fiber band 9 before the scattered light is guided to the multiplier tube 8. Even through the material to be checked is opaque in the wavelength region of the visible light beam, spectral transmittance is examined and the wavelength region, in which the material to be checked becomes opaque, is searched. The light in this wavelength region is used as projected light to the material to be measured in a scattered light type defect detecting devide. Thus the defect on the surface can be detected sensitively.
