Title: Method for measuring depth of crack in material
Inventor: YAMANAKA ICHIJI
IPC: G01B17/00
Filed: 1985-05-08
Abstract: PURPOSE:To nondestructively measure the depth of a crack at a position shallower than the wavelength of supersonic waves, by utilizing the dispersing characteristic of a ram wave that its sound velocity changes depending on the thickness of a platy section between the crack and sample surface. CONSTITUTION:When supersonic waves are irradiated upon the surface 2 of an object in a liquid 1 acting as a supersonic wave propagating medium at a prescribed incident angle theta, surface acoustic waves are excited in a platy section 4 between the surface 2 and a crack 3. When the density of the material, sound velocities of the longitudinal and transversal waves, the depth D of the crack, the thickness C of the crack 3, and the frequency F of the supersonic waves are assumed, the sound velocity of the surface acoustic waves can be found from the wave equation of the surface acoustic waves. Since the surface acoustic waves can be treated as ram waves if the thickness C is larger than the 1/10 of the wavelength of the supersonic waves, the depth D of the crack 3 can be found when the sound velocity of the surface acoustic waves at the section where the crack 3 exists is measured and compared with a previously found surface acoustic wave dispersing curve.

Title: Measuring device
Inventor: TAKAGAKI TETSUYA
IPC: G01N21/53
Filed: 1983-06-03
Abstract: PURPOSE:To measure the mixing density of foreign matters in fluid by providing a counting device which counts particles in the fluid and a flow meter which measures the flow rate of the fluid, and calculating the amount of particles per unit capacity from data of both devices. CONSTITUTION:The fluid 1 to be measured is sent to a pipe 3 by pressure through a pressure feeding means such as a pump and a pressure tank. When the fluid 1 starts flowing, the laser light source 6 of the foreign matter counting device 4 emits a laser light beam 7, which passes through a lens 8, light transmission part 5, and the fluid 1 flowing in the pipe 3, and exits from the opposite side. When the laser beam 7 illuminates foreign matter 2 in passing through the fluid 1, scattered light 9 is generated, converged through a lens 10 after passing through the transmission part 5, and detected by a photosensor 11. The frequency of the scattered light 9 by the photosensor 11 is counted by the counter 13, and the counted frequency per unit time is applied as a measurement signal to a computing element 14.

Title: Optical data transmission device
Inventor: YOSHIDA KENICHI
IPC: H04B10/07
Filed: 1978-08-11
Abstract: PURPOSE:To increase the reliability of the transmission line by giving the photoelectric conversion along with the amplification and waveform shaping to the light reflected by the half-mirror and the light reflected by the reflective mirror after passing through the half-mirror. CONSTITUTION:The light beams sent from optical fiber cable 1 are condensed through condenser lens 2 and then divided into light B to be reflected by half- mirror 3 of the dividing optical system and light A to be reflected by reflective mirror 4 after passing through mirror 3. The both light A and B are converted into the electric signals via photoelectric conversion diode 5 and then amplified and shaped into the desired waveform through amplifier/waveform shaping circuit 6. And thus the same signals are delivered at one time from output ends A and B. As a result, even if the fault occurs to either one light, the data can be transmitted via the other light system. Thus the reliability can be increased for the transmission line.

Title: Radial piston rotary pump
Inventor: ABE TAIZO
IPC: F04B1/04
Filed: 1985-05-09
Abstract: PURPOSE:To prevent the generation of surge pressure at the time when a cylinder chamber communicates with a discharge port by providing a pin member on the inside of a spring which energizes a piston fitted in a rotor toward the outside of the rotor. CONSTITUTION:A pin 101 is inserted in a piston 103 to reduce pumping volume inside the piston 103 or a cylinder chamber 104. If the volume V inside the cylinder chamber 104 could be reduced to 1/2 by a noncompressible pin 101, it is enabled to raise the pressure rise DELTAP in the cylinder chamber 104 twice as much within the same precompression region. Accordingly, the pressure in the cylinder chamber 104 is sufficiently compressed within a precompression region to be precompressed to nearly the same pressure as the discharge side pressure of a discharge port 108 or a discharge port 109 before it is communicated. Thus, the generation of surge pressure in the cylinder chamber 104 is prevented, and the pulsation in the discharge pressure of a pump can be reduced.

Title: Speed controlling method for motor
Inventor: TAMURA YASUHARU
IPC: H02P3/24
Filed: 1980-07-18
Abstract: PURPOSE:To prevent from sudden attack of braking torque onto a load and achieve quick deceleration down to a certain speed by differentially applying a measured speed signal of a motor on a control circuit for dynamic braking to suppress a dynamic braking torque on the high speed range. CONSTITUTION:When a set point of a speed setting unit 11 goes to VL by a deceleration command, the difference between VL and a measured speed VS, VL-Vs (VL<VS) is applied to a speed controller 13 and amplified. As long as VL<VS, VO=¦VL-V2¦ appears at an output terminal 14b of a discriminator 14, which is fed to a comparator part 16 to calculate the difference from the measured speed signal VS. This difference signal is fed into a brake command generator 17. From this brake command generator 17, a pulse with a phase angle corresponding to the magnitude of an input voltage to the brake command generator 17 comes out of the generator 17 to ignite a thyristor 3. Therefore, a motor 1 decelerates smoothly right after start of deceleration, and the dynamic braking torque grows up as decelerated.

Title: Coupling
Inventor: TATSUMURA TAKESHI
IPC: F16D3/78
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To provide a coupling to satisfy both buffering ability and vibration absorbing ability during the initial input of torque and a torque transmission force. SOLUTION: When, in initial input of torque, an initial tensile force is exerted on a first coupling belt 3 or 4 in linkage with the change of a distance between a connector 1 on the drive side and a connector 2 on the driven side, at this point of time, a tensile force is not exerted on a second coupling belt 5 or 6 run around the outer peripheral sides of the first coupling belt 3 or 4. Thereby, a spring constant in a twist direction is low and an impact during input of initial torque is effectively relaxed.  When a relative displacement amount between the connector 1 on the drive side and the connector 2 on the drive side is increased to a value exceeding a given value due to the increase of torque, at this point of time, a tension is also applied on the second coupling belt 4 or 6 and a tensile force is exerted on both the first and second coupling belts 4 and 6, whereby torque is reliably transmitted.
