Title: Method for locating partial discharge position
Inventor: SADAMOTO KENJI
IPC: G01R31/08
Filed: 1988-01-21
Abstract: PURPOSE:To locate the position of partial discharge simply and rapidly with high accuracy and, at the same time, to determine the speed of the ultrasonic waves in a medium, by detecting the ultrasonic waves generated by partial discharge by at least five ultrasonic sensors. CONSTITUTION:Five ultrasonic sensors 3a-3e are mounted to the connection part 2 of a power cable at positions easy to detect ultrasonic waves and the outputs thereof are connected to a waveform memory apparatus 5 while the apparatus 5 is connected to an operation apparatus 6. When partial discharge is generated at a partial discharge generating position 4, mechanical vibration is generated with the generation of partial discharge and becomes ultrasonic waves to propagate through the connection part 2 and reaches the sensors 3a-3e to be converted to electric signals. Subsequently, the distance between the partial discharge position and one of the ultrasonic sensors is calculated and each detection time difference of the ultrasonic signal waveform between one ultrasonic sensor and each of the other ultrasonic sensors and, from the distance and each detection time difference, the speed of the ultrasonic waves propagating through the medium of an object is determined to locate a partial discharge generating position.

Filed: 1985-01-24
Abstract: PURPOSE:To form a good metal flow with preventing the thrust in the axial direction against a reducer by pinching both sides of a blank with a fixed pressing member and mobile pressing member and by fixing the respective pressing member to the rotary shaft. CONSTITUTION:A blank W is pinched by a fixed and mobile pressing member 6, 7 by insterting the blank W into a rotary shaft 3 and then by inserting the blank W into a rotary shaft 3 and then by insterting the mobile pressing member 7 into the rotary shaft 3, and fixed by a snap ring 14. Thereafter the pressure of a forming roller 4 is supported by pressing the blank W to the forming roller 4 and simultaneously by bringing a supporting roller 5 into contact with the outer periphery of both pressing members 6, 7. Further when the forming roller 4 is pushed in, the blank W is plastically deformed and the V pulley A having the V groove profiling to the forming roller 4 is formed. In this case excess metals are built up and burrs are caused between the forming roller 4 and both pressing members 6, 7 which pinch the former but these are removed by the attached cutting bit, etc.

IPC: B41J2/125
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To measure the flow rate of ink without using an operation mechanism having possibility to lower the reliability by moving ink in field and detecting a current induced in the ink. SOLUTION: A flow rate measuring mechanism 12 is disposed in front of the channel of nozzle and connected with a tube 13. Electrodes 16a, 16b are disposed oppositely therein and connected with an electric circuit 17 provided with an ammeter 18. The flow rate measuring mechanism 12 is set in a field. Ink is introduced through the tube 13 to the flow rate measuring mechanism 12. The ink has vector in the flow direction. Since the measuring mechanism is set in the field of vector of field direction, a current is induced in the direction of electrodes 16a, 16b and detected by the ammeter. Since the flow rate of ink is correlated with the detected current, flow rate can be detected from a specified relationship between the flow rate and current value.

IPC: A61B5/055
Filed: 1984-01-25
Abstract: PURPOSE:To perform the recording of data at a high speed, by forcibly returning magnetization to a thermal equilibrium state after a series of scannings to shorten a stand- by time. CONSTITUTION:In order to generate nuclear magnetic resonance to the atomic nucleus of the atom forming the structure of an object to be examined, said object to be examined is excited by a magnetic field in a Z-direction through a static magnetic field control circuit 2 and a static magnetic field coil 1, and a magnetic field through an exciting coil 5 by the 90 deg. pulse from an oscillator 6. Subsequently, a nuclear magnetic resonance signal due to a two-dimensional magnetic gradient through a gradient magnetic field control circuit 4 and a gradient magnetic field coil 3 is detected by a detection coil 8 and a series of scannings are finished. Succeedingly, a second 90 deg. pulse is applied to the coil 5 and the magnetic field in the Z-direction is applied to direct magnetism upwardly and a homogeneity spoil pulse is applied to the coil 3. Whereupon, magnetism is forcibly made thermally equilibrium and a magnetism vector coincides with a static magnetic field direction. By this mechanism, the correlation with the next sequence is eliminated and the next scanning can be started directly and data recording is performed at a high speed.
