Title: Distribution type optical temperature sensor
Inventor: KATOU HITOSHI
IPC: G01K11/12
Filed: 1990-02-23
Abstract: PURPOSE:To shorten the time for measurement by constituting the sensor in such a manner that a 2nd (1st) temp. detecting section transfers internal data to a display means while a 1st (2nd) temp. detecting section collects the data. CONSTITUTION:A microcomputer 11 outputs a start command to a laser driving circuit 21 of the temp. detecting section 13, clears the respective memories 27, 29 in the temp. detecting sections 13, 14 and changes over an optical switch to the temp. detecting section 13 side. The circuit 21 impulsively drives a semiconductor laser 1 upon receipt of the command from the computer 11. The impulsive light from the laser 1 is radiated in this way and this light is introduced through a branching device 3, etc., to an optical fiber 16. Raman scattered light is generated in this fiber 16 and the scattered light is introduced to the branching devices 6, 7 where Stoke's light and anti-Stoke's light are extracted. The intensities of the light therefrom are converted to analog signals by photodetectors 8, 9. The analog signals are outputted to adders 25, 26 after A/D conversion 23, 24 and are further added with the data in the memories 27, 29.

IPC: G11B7/135
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To provide an optical pickup device of smaller size and light load, capable of reading disks of different thickness and having high optical efficiency. SOLUTION: An optical pickup device is constituted of an objective lens 21, an actuator 22 to move the lens 21, a substrate 11 having a hologram 13 on the upper surface, and a moving member 12 to move the substrate 11. The hologram 13 is blazed to function as a concave lens. The moving member 12 moves the substrate 11 in a straight-line reciprocating motion to constitute the hologram 13 so as to freely move into and out of a flux of light L of a laser. When the hologram 13 is inserted in the flux of light L, the length between the objective lens 21 and a light condensing position O becomes longer to correspond to the bit of a CD 31; on the contrary, when the hologram 13 is detached from the flux of light L, the length to the light condensing position O becomes shorter to correspond to the bit of a Digital Video Disk 7.

Title: Current detector
Inventor: YAMASHITA MITSUO
IPC: G01R31/02
Filed: 1987-02-27
Abstract: PURPOSE:To obtain superior detection sensitivity and to enable current detection without waveform distortion by converting the unbalanced output of a bridge circuit which has a couple of circumferential magnetic flux sensors as two sides into a direct current. CONSTITUTION:The bridge circuit 5 shown in a figure (a) is formed which has the circumferential magnetic flux sensors 1A and 1B formed by winding high-frequency exciting coils 12 around amorphous thin wires 11 shown in a figure as its two sides. Then the sensors 1A and 1B are arranged in the gap part 3 between annular magnetic cores 2A and 2B in parallel to the magnetic path directions of pieces of circumferential magnetic flux phii of magnetic cores 2A and 2B so that high frequency magnetic fields phiA and phiB are in the mutually opposite directions. Then a high-frequency current is supplied from an oscillator 4 to the circuit 5 to magnetize thin wires 11 at the high frequency so that the thin wires 11 enter a magnetic saturation range. Consequently, unbalance currents are generated to product plus magnetic flux phii in one thin wire 11 with one of the pieces of magnetic flux phiA and phiB and minus magnetic flux with the other. Therefore, one sensor increases in excitation inductance, but the other decreases. Those inductance variations, i.e. the generation of a current to be detected is detected and the unbalanced output is converted by a detecting circuit 9 into a direct current to detect the current without being affected by waveform distortion.

Title: Cell discarding method and device realizing the method
Inventor: NAGATA SHUNSAKU
IPC: H04Q3/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce wasteful resource consumption and the drop of throughput and to solve the limitation of a simultaneous connection number by collectively discarding the fixed number of cells when the queue length of a buffer in a node exceeds a defined threshold. SOLUTION: A buffer monitoring part 2 always monitors queue length of a buffer 1. When the buffer 1 receives a cell, and when it exceeds the queue length of the buffer and a threshold S1 that is previously defined in the part 2, a comparing part 3 notifies the effect to a buffer controlling part 4. When the part 4 receives the notification from the part 3, it discards the fixed number of cells from the buffer 1. However, when queue length does not exceed the threshold, the part 4 does nothing. This reduces wasteful resource consumption. For instance, an inputting side does not continuously discard cells in a congestion state nor wastefully transfers cells that are discarded by a receiving terminal even when plural connections share a buffer.

Abstract: PURPOSE:To enable polishing, with high efficiency, a layer altered with small work by sprinkling fine particles suspended in a machining liquid on a resin surface plate having high viscosity and elasticity and rotating said plate, pressing a ferrite crystal to said plate and carrying out mutually sliding machining. CONSTITUTION:A sample attaching member 3 on which ferrite crystal pieces 4 are attached is rotated. On the other hand, a machining liquid 6 is fed from a machining liquid feed nozzle 5 onto a resin surface plate 2 installed on a stainless base 1, which is being rotated to rotate the surface plate 2, thereby slidingly machining the sample pieces 4. The machining liquid 6 fed onto the surface plate 2 is retained in the grooves 201 and the liquid 6 in the groove 201 supplies fine particles being suspended, onto the ridge parts of the surface plate 2. The fine particles are enbedded and retained on the surface plate 2, and minutely remove the ferrite crystal through mechanical action. Also, the acid machining liquid removes the ferrite crystal by chemically melting means. Thus, by the mechanical action of the fine particles and the chemical action of the acid liquid, a high rate of machining and formation of a machining surface into a layer altered with small work can be obtained.

Filed: 1981-03-30
Abstract: PURPOSE:To prevent the damaging of a mold and a core and to eliminate the cause for defective castings by coating oil on the bottom surface of a weight placed on the mold thereby reducing the evaporating and explosive force of the water drops stuck on the bottom surface of the weight. CONSTITUTION:During transporting of a weight 1, the oil 3 in a pressure vessel 4 is coated on the bottom surface of the weight 1 by operating an oil coating gun 6. The oil supply part of the gun 6 communicates with the inside of the oil 3 in the vessel 4 through a pipe 7 and the injection pressure supply part of the gun 6 communicates with a compressed air source through a piping 8. Since the oil 3 is coated on the bottom surface of the weight 1 placed on the mold during charging of molten metal to the mold in this way, the evaporating and explosive force of the water drops stuck on the bottom surface of the weight is reduced.

Title: Contactless switch
Inventor: TAKEGAHARA IKUO
IPC: H01H55/00
Filed: 1990-02-28
Abstract: PURPOSE:To enhance the contacting reliability of a contact of a switch and prolong its lifetime by entering a pulse signal which is generated by a magneto- striction pulse generating element when the position of a yoke changes, and emitting a switching signal in conformity to the entered pulse signal. CONSTITUTION:When a push button 8 is pushed to cause one end of an arm 6 to move downward, the both ends of a yoke 7 approach the both poles of a permanent magnet 11. Thereby a closed magnetic circuit is formed from the magnet 11 and yoke 7, and the magnetic flux generated from the magnet 11 does not leak to the outside, but is introduced into the yoke 7. Accordingly the magnetic flux given to a Wiegand element 20 will solely be that from No.2 permanent magnet 12, and the core of the element 20 will be magnetized in the opposite direction. Because the direction of manetization of this core is reversed, positive pulses are generated at the ends of a sensing coil 23 and fed to an output circuit 30. When the pushing of a button is released, the yoke 7 is restituted. Accordingly the direction of magnetization of the element 20 is returned to its original state. Thus negative pulses are generated across the coil 23 and fed to the output circuit 30.
