Title: Inspecting method for cut section of optical fiber
Inventor: MIYAJIMA YOSHIAKI
IPC: G01N29/14
Filed: 1985-07-31
Abstract: PURPOSE:To easily identify the condition of the cut section and an optical fiber, by detecting the acoustic emission produced when the optical fiber is cut with a sensor. CONSTITUTION:After an optical fiber (not shown in the figure) is set on a plate spring 1 or optical fiber guiding plate 7, a fine streak is formed in the surface of the fiber with an edge 2. Then the optical fiber is cut by giving a bending stration to the fiber by bending the plate sprint 1. Since the stress- strain energy is released at the moment when the optical fiber is cut, an acoustic pulse (acoustic emission) is produced at the time of destruction. The acoustic pulse is detected with a sensor 8 and observed by means of an oscilloscope 10 through an amplifier 9. Since the acoustic emission is continuously observed for a period of about three seconds when the cut section becomes a flat perpendicular face, the cut condition can be identified easily.

Title: Motor controller
Inventor: AKAHA TSUTOMU
IPC: H02P7/00
Filed: 1990-06-26
Abstract: PURPOSE:To detect layer short circuit as well as disconnection of exciting coil through a simple constitution by constituting a motor controller of a switch, an exciting coil, a command switch, a capacitor forming a resonance circuit, a high frequency power supply, and a circuit for judging variation of resonance conditions. CONSTITUTION:Upon turn ON of a start command switch 12a, an exciting coil 14 is excited to close an electromagnetic contactor 5 thus starting a motor 2. Upon turning a stop command switch 12b OFF under operating condition of motor 2, the exciting coil 14 is opened. A high frequency oscillation circuit 16 normally applies a high frequency low voltage onto a resonance circuit 19 including the exciting coil 14 regardless of the state of the electromagnetic contactor 5. Under normal state where the exciting coil 14 is not short-circuited nor disconnected, the resonance circuit 19 is in resonant state and a maximum current flows through a voltage conversion resistor 18 but upon occurrence of layer short circuit, substantial variation of the number of turn of the coil causes variation of inductance to bring the resonance circuit 19 into non-resonant state and thereby a minimum current flows through the voltage conversion resistor 18.

Title: Voltage measuring system
Inventor: KOGANEI YUKIO
IPC: G01R19/00
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To provide a voltage measuring system capable of performing inexpensive and highly precise measurement. SOLUTION: This voltage measuring system is composed of a sensor 1 and a signal processing circuit 2. The sensor 1 is directly connected to a non- stabilized power supply line 3 and detects the change of a physical quantity to be measured as the change of a voltage value. The signal processing circuit 2 executes A/D conversion of an output voltage V1 from the sensor 1 and thereafter executes signal processing. The signal processing circuit 2 cancels fluctuation of an output voltage of the sensor 1 based on voltage fluctuation of the power supply line 3 by using a reference voltage V2 obtained by dividing a power supply voltage of the power supply line 3 at a fixed ratio.

Title: Clock generator
Inventor: OI MASUMI
IPC: H03K5/15
Filed: 1989-06-28
Abstract: PURPOSE:To simply obtain a biphase clock signal without overlap by taking inverted exclusive OR (ENOR) between a signal retarded by an inverter and an input signal and taking AND between its output and a signal retarded by the inverter. CONSTITUTION:When an input clock signal is inputted to an input terminal 1, a waveform at a point A is a waveform of an inverted input signal retarded by a delay of an inverter 4 and a waveform at a point B is retarded by a delay of an inverter 5. Then the input signal and the signal at the point B are exclusively NORed at an ENOR gate 6 to obtain a signal at a point C having a period of 'L' by the delay. The signal at the point C and the signals at the points A, B are ANDed by AND gates 7, 8 respectively. Thus, biphase output signals 1, 2 without overlap between periods of 'L' and 'H' both the periods are obtained.

Title: Ceramic wiring board, its production and conductive paste
Inventor: KODERA EIJI
IPC: H05K1/09
Filed: 1995-06-08
Abstract: PURPOSE: To produce a reliable ceramic wiring board in which open circuit is prevented while increasing the yield by forming a wiring through an inexpensive technology for forming a thick film such that the minimum width of wiring and the particle size of glass frit contained in a conductive paste satisfy a specified relationship. CONSTITUTION: When the particle size D of glass frit mixed in a conductive paste is sufficiently smaller than the minimum line width Wmin of wiring formed by sintering, the size of defect, if any, in the wiring is small. Consequently, the effect is insignificant and does not cause any open circuit. The particle size D of glass frit and the minimum line width Wmin simply require to satisfy a relationship D90<=1/6Wmin . When a ceramic wiring board S is produced using such conductive paste, the wiring is not open circuited. Furthermore the defect present in such wiring is small and open circuit by a current flowing through the wiring or a stress acting on the board can be suppressed.

Abstract: PURPOSE:To allow the usage of a corrosive gas at a temperature more than 1,000 deg.C as well as to prevent leaks and breakage by disposing a compression spring in a space between a ceramic pipe for transmitting heated fluid and a wall surface to take up expansion and contraction of the pipe in the axial direction. CONSTITUTION:A ceramic pipe 5 is used as a heat conducting pipe so that the heat exchange may be conducted with the exhaust gas at a high temperature exceeding 1,000 deg.C. Further, the recovery of heat from a corrosive gas is also intended. When the high temperature exhaust gas is introduced into a framebody 1, respective ceramic pipes 5 are expanded significantly by heat, but the amount of expansion is uneven. However, the respective ceramic pipes 5 are movable in the axial direction by means of a compression spring 14 disposed between a support pipe 8 and a wall surface 2, the uneven thermal expansion is independently absorbed by the respective compression springs 14, and so, the breakage of the ceramic pipes 5 due to the thermal stress can be prevented.
