Patent JP-H0714707-A (JP)
Title: Arrester for power transmission
Inventor: SAKURABA YUKIYA
IPC: H01C7/12
Filed: 1993-06-23
Abstract: PURPOSE:To provide an arrester for power transmission in which flashover takes place easily across a series gap upon occurrence of lightning surge to protect the transmission and distribution facility positively without causing dielectric breakdown of the arrester. CONSTITUTION:Nonlinear resistor elements 12 are laminated in a cylindrical dielectric container and connected in parallel with a resistor 19. The resistor 19 normally exhibits lower resistance than that of the element 12 and thereby the bearing voltage of a gap metal 18 increases to effect positive flashover. Upon occurrence of lightning surge, resistance of the resistor 19 increases over that of the element 12 and thereby causes no trouble in the interruption of follow current.

Title: Polarization surface preserving optical fiber type magnetic field sensor
Inventor: IIZUKA TOSHIO
IPC: G02B6/024
Filed: 1982-08-31
Abstract: PURPOSE:To enable measurement in a high temp. atmosphere without using a polarizer and an analyser, by fixing the end surface polarizing axes of polarization surface preserving optical fibers opposed to each other so as to hold a Faraday rotary element therebetween in a mutually 45 deg. shifted state. CONSTITUTION:Laser beam from a light source 1 is projected into a Faraday rotary element 106 through a converging lens 102, a beam sending side polarization surface preserving optical fiber 103 and a collimator 104 while the linear polarizability thereof is enhanced by a polarizer 105. The emitted beam from the element 106 is received by a light receiver 108, a condensing lens 102', a polarization surface preserving optical fiber 103' fixed so as to incline the polarizing axis 45 deg. with respect to the polarization surface of the emitted light of the element 106 in the case of no-magnetic field, a collimator 104' or the like. Therefore, it is unnecessary to provide a polarizer or an analyser resulting in characteristic deterioration at a high temp. in the vicinity of the Faraday rotary element and, because the polarizing axes in front of and rear to the Farday rotary element are mutually inclined by 45 deg., magnetic field measurement can be performed in high preciseness at a high temp.

Abstract: PROBLEM TO BE SOLVED: To reduce the error of the observer estimation value and to improve the damping effect of a robot arm at the time of an observer application even though the value of a measurable state variable to be fed back to a control part is not suitable to the calculation of estimation for the observer. SOLUTION: An observer state variable calculation part 104 calculates a measurable state variable by an calculation method that is suitable to the calculation of estimation for an observer. A state variable calculation part 103 calculates a measurable state variable to be fed back to a control part 101 which controls a joint drive servo motor based on the state of a servo motor. Then the part 104 calculates a measurable state variable which is used at an observer calculation part 105 for estimation of an unmeasurable state variable.

Title: Driving circuit for stepping motor
Inventor: SENSUI KIYOSHI
IPC: H02P8/16
Filed: 1989-06-13
Abstract: PURPOSE:To reduce energy of a motor driving by inducing a flyback current in a coil wound on the same pole as that of a coil which is turned OFF, and feeding it back to a driving current. CONSTITUTION:When a driver 10 is turned OFF, the current Iphi1 of a coil 51 of phi1 fails to flow. A current substantially equivalent to the Iphi1 is induced in a coil 52 of phi3. Since the polarities of the coils 51, 52 are normally reverse, the directions of the induced currents are reverse to the case of the Iphi1. The induced current flows from the ground to a power source VD 37 through flyback current attenuating diodes 21, 22, the coil 52 and a diode 17. Thus, the flyback current induced in the coil 51 is absorbed by the inductance of the diodes 21, 22 and the coil 52 and the power source VD 37 to be attenuated. In this manner, the flyback current is abruptly attenuated. Further, its cost is low, and a problem such as temperature rise can be solved.

Title: Optical waveguide circuit
Inventor: TERUI HIROSHI
IPC: G02B6/122
Filed: 1995-06-19
Abstract: PURPOSE: To prevent scattered light generated in an optical waveguide from straying into other waveguides and reduce a crosstalk quantity by removing a new clad part of a propagation path for signal light up to desired thickness and sticking a light absorbing material on the part. CONSTITUTION: The clad part 3 which is unneccessary for the propagation of waveguide light is removed up to desired thickness. A light shield process is performed by sticking an absorbed 5 on the entire surface of this circuit by vapor deposition, coating, or printing, etc. Consequently, scattered light which is generated during the propagation of waveguide light and propagated in the clad 3' is absorbed by the interface between the clad 3' and light absorber 5, so crosstalk can be prevented from being caused. The sticking position of the light absorber 5 is sufficiently distant from core patterns 1 and 2, so the propagation loss may not be worsened.  The depth to which the unncessary clad part is removed is determined in total consideration of the time of the removal processing, the light absorption performance of the light absorber 5, the influence of stress between the clad layer and substrate 4 on the circuit performance, requested crosstalk, etc.

Title: Platen for thermal transfer printer with relief part at eachend
Inventor: JIEEMUZU EDOWAADO PITSUKARINGU
IPC: B41J11/04
Filed: 1995-06-19
Abstract: PURPOSE: To protect a printed matter against the occurrence of an incomplete line or scratch by preventing the opposite ends of a platen from swelling for pushing a dye receiver media into the edge of a print head. CONSTITUTION: A resistive thermal printer 10 receives dye donor and dye receiver media 16, 18 between a print head 14 and a platen 20' having an elastomeric surface. The platen and one media is made wider than the print head, and the other media is made narrower than the print head, whereby the pressure between the print head and the platen with the media therebetween, tends to compress the platen in the region of the narrow medium. End portions of the platen beyond the narrow medium are relieved, so as not be compressed by pressure between the print head and the platen.

Filed: 1978-12-12
Abstract: PURPOSE: To miniaturize and economize a circuit, by displaying conditions in the case when there happens a trouble by the output of detectors for detecting the trouble of a printer, and by using starting pulses as resetting pulses.  
     CONSTITUTION: Detectors 13, 14, 15 consisting of luminous diodes and semiconductor light receiving elements are mounted in order to monitor the operation of this mechanism. If only a signal 21 is obtained when there happens a trouble, the sucking force of a solenoid 12 is insufficient or a shift-in stop lever 9 is broken or damaged or the adjustment of the lever is destroyed. When the signal 21 and an output signal 22 are not gained, a cause of the trouble is restricted to the parts of a clutch 19, a shift cam 7 and a shift lever 6. When the three of the signal 21 and output signals 22, 23 are acquired and the operation of shift-in and shift-out is imperfect, parts after the shift lever 6 are damaged. Thus, a location causing the trouble can be detected for a short time when there happens the trouble by installing detectors for monitoring operation to one portion of a mechanism portion.
