Title: Power unit for work without outage
Inventor: MATSUKAWA MITSURU
IPC: G05F1/70
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent a power unit for work without outage from being damaged by a power flow when the power unit is operated while the unit is an interconnected with a system power source by readily and inexpensively controlling the output of a feeding section (inverter feeding section) constituted in a stationary converter so that the phase of the output can lead that of the system power source. SOLUTION: A power unit for work without outage is provided with a DC detecting section 12 which computes the difference between the DC voltage on the input side of an inverter feeding section 6 which is changed by the power flow on the output side of the feeding section and a reference voltage and forms a flow detecting signal which changes in accordance with the power flow flowing in the feeding section 6, a multiplying section 16 which multiplies a reference signal with a leading phase formed by differentiating the detecting signal of a system voltage by the flow detecting signal and forms a corrected signal with a leading phase by correcting the reference signal in accordance with the power flow flowing in the feeding section 6,  and a drive control section 11 by forming a drive control signal which is used for controlling the feeding section 6 to output electric power with a leading-phase by adding the system voltage detecting signal to the corrected signal and drives the feeding section 6 with the drive control signal.

Title: Magnetizing apparatus for rotary encoder
Inventor: MATSUZAKI TAKASHI
IPC: G01D5/245
Filed: 1987-10-01
Abstract: PURPOSE:To perform highly accurate magnetization with a simple structure, by providing a judging circuit, which compares the time difference between the rise-up and the fall-down of a magnetizing signal, and providing a minute- angle adjusting mechanism for a moving stage of a magnetizing head. CONSTITUTION:First and second magnetizing heads 1 and 2, which magnetize first and second tracks, are mounted on sliding stages 3 and 4. The sliding stage 4 is fixed to a moving base stage 13. A thin film resistor 18 comprising a ferromagnetic body is provided on another sliding stage so as to monitor magnetizing signals. When a work 5 is magnetized with a reference encoder 14, whether the phase difference between the first and second tracks, i.e., the time difference between the rise-up and the fall-down of the signals, is smaller than the reference time or not is judged with the resistor 18 and a judging circuit. When the time difference is large, the moving base stage 13, on which the magnetizing head 2 is mounted, is displaced by a minute angle. The time difference is made to be within the reference time. Therefore, highly accurate magnetization is performed.

Title: Nuclear magnetic resonance imaging system
Inventor: SANO KOICHI
IPC: G16H10/60
Filed: 1985-11-08
Abstract: PURPOSE:To attain the practical and quantitative measurement of the blood flowing speed in a direction (x) by reducing the movement components of the subjects in the directions excepting for the direction of a reading slant magnetic field, i.e., the direction (x) so that the effect of said movement components can be neglected to the phase. CONSTITUTION:A sequence control part 201 controls a high frequency pulse transmitter 202, a magnetic field control part 203 which produces a mag netostatic field and a slant magnetic field, and a receiver for 205 for the NMR signal produced from a subject and displays the pictures reformed by a processor 206 on a CRT 207. The polarities are inverted between the slant magnetic fields GZ305 and GZ302. The phase change due to the flowing speed of the GZ302 is set in the direction opposite to the phase change of the GZ305 and the application time of the GZ305 is set at a level about 1.5 times as much as a high frequency pulse width 304. The phase angle of the NMR signal has no relation with the flowing speed in the direction (z), i.e., the slice vertical direction and is proportional to the direction of the reading slant magnetic field, i.e., the direction (x).

Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To accurately stick together an image sheet and a lenticular plate. SOLUTION: The directions and phases of an image sheet 10 and a lenticular plate 11 are adjusted by using a positioning pallet 20. The pallet 20 is set on a sticking base 102.

Title: Phase locked loop circuit

IPC: H03L7/10
Filed: 1992-09-18
Abstract: PURPOSE:To shorten the time required for the normal operation of a phase locked loop PLL circuit at the time of application of a power supply and also to shorten the lock-up time by inputting a control signal to a charge pumping circuit from the outside of a PLL in place of the output of a phase comparator. CONSTITUTION:When a power supply is applied to PLL circuit, a switch circuit 10 functions to input a control signal B or C to a charge pumping circuit 22 from the outside of a PLL in place of the outputs P and N of a phase comparator 21. Under such conditions, the DC component of the output of the circuit 22 can be changed as desired by control of the signal B or C. Then the control voltage level of a VCD 24 can be set at the value close to the voltage level set in a lock state by the selective input of both signals B and C having the logical levels corresponding to the phase difference detection signals P and N of both output nodes of the comparator 21 respectively. In such a constitution, the lock detection output given from a lock/unlock detecting circuit 26 is fetched by an MPV and a lock state is detected when the PLL circuit is immediately locked. Then the circuit 10 undergoes the switch control and the PLL circuit has a normal operation.

IPC: F01L1/053
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To provide the structure of a mounting part for a camshaft rotation sensor capable of easily heightening the relative positional accuracy with a camshaft. SOLUTION: The camshaft rotation sensor is to sense the rotating angle of a camshaft supported by a cam holder (lower cam holder 12 and upper cam holder 13). The structure of the mounting part of the rotation sensor is configured so that a thrust plate (17) fixed to one end of the camshaft for specifying the axial direction position of the camshaft while abutting on the axial direction end face (thrust receiving surface 31) of the cam holder, is furnished with a part to be sensed (projection 18), and that a sensor (proximity sensor 23) for sensing passage of the part to be sensed from the axial direction is mounted on a member (sensor mounting wall 20) integrally formed with the cam holder. This allows easily heightening the relative positional accuracy of the part to be sensed with respect to the sensor mounting part, so that a high sensing accuracy is obtained.  Because the sensor and a head cover can be mounted and removed independently of each other, maintenance and repairing properties can be enhanced.

Abstract: PURPOSE:To produce a grain-oriented silicon steel sheet having superior mag netic properties uniform in a rolling direction and also having superior surface by specifying respective temp. regions and rolling reductions in the first pass and the second pass at the time of roughing in a hot rolling stage. CONSTITUTION:At the time of roughing in the hot rolling stage for a silicon- containing steel slab, rolling is performed in the first pass at >=1350 deg.C at 3-<20% rolling reduction, and also rolling is performed in the second pass under the condition where rolling temp. T is >=1350 deg.C and rolling reduction R satisfies the relationship in an inequality 60>=R(%)>=0.2T+300. Subsequently, the resulting plate is cold-rolled once or is cold-rolled twice while process- annealed between the cold rolling stages so as to be formed into the final sheet thickness. Then, the sheet is subjected to decarburizing annealing, and, after a separation agent at annealing is applied to the sheet, finish annealing is car ried out. By this method, the merits of a hot strip mill can be made the most of, and the grain-oriented silicon steel sheet excellent in magnetic properties and surface characteristics can be stably obtained.
