Abstract: PROBLEM TO BE SOLVED: To lessen a copper loss by conducting a field-weakening control without causing field-weakening current to flow. SOLUTION: Openings 21 for adjusting a magnetic resistance are formed in a main body 7 of a stator. The openings 21 are positioned on a path of magnetic flux which is generated by a field generating means of a rotor 5 and which passes through the main body 7 of the stator. And, adjustment plugs 23 which have a permeability anisotropy are inserted into the openings 21 for adjusting a magnetic resistance. In order to adjust the angles the adjustment plugs 23 make with the magnetic paths in the openings 21 for adjusting a magnetic resistance, plug angle actuators are installed. A magnetic resistance of the main body 7 of the stator is adjusted by the angles of the adjustment plugs 23 and thereby a field-weakening control is conducted.  A motor 1 is installed in a vehicle and the angles of the adjustment plugs 23 in the openings for adjusting a magnetic resistance are adjusted according to the rotating speed of the motor 1.

Title: Connecting device for concrete pressure feed pipe
Inventor: OKADA TOMIO
IPC: E04G21/04
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To make a concrete placing work smooth and efficient by providing a discharge port symmetrically to a center axis and each branched pipe with a gate valve so as to incline along a flow direction, and sliding the valve to distribute a pressure-feed concrete. SOLUTION: Each of branched pipes 3, 4 of a Y-shaped joint provided on the way of a ready-mixed concrete pressure feed pipe is provided with a gate valve (a slide valve) so that an attaching angle θ may be an acute angle to form a connecting device (a branching device) 1. In addition, a branched inner wall surface 5 is formed in inclined faces 5A, 5B having a V-shaped section and moreover wholly circular arc-shaped, and even in the case where a ready- mixed concrete pressure fed from a straight pipe 2 strikes against the inner wall face, it is smoothly distributed by the branched pipe 3 or 4. A rack 13 and a pinion 14 are driven to slide the shutter plate 12 of the gate valve 11 for opening and closing the gate valve 11, and the pressure of the concrete is prevented from acting rectangularly on the plate 12.  Thus the accumulation of a small stone in the ready-mixed concrete can thereby be prevented to improve a concrete placing workability.

Filed: 1994-03-08
Abstract: PURPOSE:To obtain a stable circuit which exerts no influence upon a threshold voltage even in the case of variation in duty by comparing the peak values of data and inverted data detected by peak detection circuits and operating the threshold voltage on the basis of the comparison result. CONSTITUTION:The peak values which are detected by the peak detection circuits 4 and 3 are inputted to a differential couple 11 and inputted to a differential couple 14 through buffers. When the threshold voltage V1 rises above the center value of an input signal to cause the peak value of inverted data at a point (a) to become high and the peak value of data at a point (b) to become low, the peak value at a point (c) is larger than the peak value at a point (d) and the voltage of a capacitor C5 is higher than the voltage of C6 and inputted to the differential couple 11. Then the voltage at a point (f) is higher than the voltage at a point (e) and the voltage at a point (h) of the base of the transistor TR3 of a differential couple 14 becomes higher than the voltage at a point (hg) of the base of the TR4. Then a current is discharged from C2 to flow to a TR5 and lower the voltage L1 and when the voltage V1 drops below the center value of the input signal, the current is charged in the C2 to raise the voltage V1.

Title: Sodium-sulfur battery module
Inventor: TOKOI HIROMI
IPC: H01M10/60
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To attain a uniform battery temperature inside a module by collecting heat generated in a high-temperature part in the module as the latent heat of vaporization of an operating fluid, and radiating the heat as the latent heat of condensation at a low-temperature part. SOLUTION: A wick 2 of large capillary force is provided around a cell 1 mounted in a heat insulating container 4 and is impregnated with an operating fluid 3. With a rise in temperature of the cell 1, the operating fluid 3 attains a high temperature and vaporizes. The operating fluid 3 vaporized is transferred to a low temperature part and condensed by cooling using a cooling fin 5. The operating fluid 3 condensed drops by gravity and flows back to the wick 2 on the surface 1 of the cell and to the bottom of the heat insulating container. With this change in phase of the operating fluid 3, the latent heat of the operating fluid 3 is taken from a high-temperature cell to cool the high-temperature cell.  Therefore, the cells in a sodium-sulfur battery module can be held at a uniform temperature regardless of the arrangement of the cells therein, and the temperature difference between the cells along the direction of an axis can be made as small as possible.

Title: Line synchronizing signal detector
Inventor: JIYANNMARUKU MERUBARU
IPC: H04N5/10
Filed: 1989-02-16
Abstract: PURPOSE: To provide a video signal detecting circuit which is completely in a digital system and does not use an external capacitor and whose operation is independent of the rocking of a PLL by inhibiting the operation in a loop when a line synchronizing signal does not exist and switching a voltage control circuit into the loop when the existence of a synchronizing signal is detected inside a detection window and a synchronous top of a prescribed number is detected. CONSTITUTION: When a synchronizing signal is detected, a line synchronizing signal connects a VCO 8 into a loop, and when a line synchronizing signal does not exist, it is supplied to a control terminal 20 of the VCO 8 so that the VCO 8 may operate in a free frequency. In this case, an AND gate 40 becomes '1' in accordance with the count of the duration of 60 microseconds and opens a window and if a line synchronization pulse is not applied to other input of an AND gate 24, the window is 'closed' after 10 microseconds. If a line synchronization pulse occurs during a window period, the count of an UP/DOWN counter 28 is increased by one unit and when it reaches a prescribed number, an enable signal that makes the VCO 8 connect into the loop again is generated.
