Title: Uninterruptible power supply device
Inventor: HIRATA AKIO
IPC: H02J9/06
Filed: 1990-09-13
Abstract: PURPOSE:To reduce voltage fluctuation in load feed, to prevent the operation fault of a load side equipment and to improve profitability by lengthening the distance of a DC electric wiring and shortening a wiring distance between an inverter having a voltage control function and load. CONSTITUTION:The AC power of an AC input power supply 11 is converted into DC power by a rectifier 12, the DC power is DC-distributed into each inverter 161-163 by a DC bus 15, and DC power is inverted into AC power by each inverter 161-163. Each inverter 161-163 is changed into inverters, in which output voltage can be controlled, by known PWM control, etc., thus turning AC power supplied to each load 171-173 from each inverter 161-163 into stabilized AC power, in which voltage fluctuation is inhibited. When a momentary voltage drop, service interruption, etc., are generated in the AC input power supply 11, the DC power of a battery 13 is fed in place of the output power of the rectifier 12, and each load 171-173 can continuously be supplied with uninterrupted AC power.

Title: Retrieving device for information track
Inventor: AKAHORI HIROSHI
IPC: G11B21/08
Filed: 1987-09-25
Abstract: PURPOSE:To retrieve a track at high speed and stably by giving an input identical with the moving means of a movable carriage provided with a tracking element to a state space model, assuming a relative speed for the movable carriage of the tracking element, and controlling it so as to be constant. CONSTITUTION:When a desired track address is inputted to an address input 21, a tracking and a phase shifting control are not operated, and a switching circuit 24 is switched to a signal from an offset input generator 23. A control circuit 19 moves a movable carriage 12 in a desired track direction, and the input identical with that of a linear motor 13 is given to the generator 23. The generator 23 generates an offset input so that the movement of a tracking element 10 may be reduced due to the movement of the movable carriage 12, and impresses it to the element 10. That is, the relative position and the relative speed of the element 10 in respect to the movable carriage are assumed, they are fed back to the state space model, and the assumed relative position is set not to vibrate. The feedback quantity at such a time is the output of the generator 23. Thus, the track can be retrieved at high speed.

Abstract: PURPOSE:To enable the optimum hierarchically restored display of various images differing gradation change characteristics. CONSTITUTION:A first DCT coefficient holding part 103 inputs/holds a two-dimensional DCT coefficient block for one image in each hierarchy from a DCT coefficient extraction part 102. A valid coefficient extraction part 104 extracts the number of valid coefficients for each two-dimensional DCT coefficient block as mentioned above, and the extracted numbers are successively compared with the prescribed number of threshold values by a comparator part 106.

Filed: 1989-09-18
Abstract: PURPOSE:To improve the resistance to surge by forming a low concentration impurity region and a PN junction region on the peripheral part of a high concentration drain region, and increasing the junction capacitance of the drain region and a semiconductor substrate. CONSTITUTION:Two MISFET's 30 of high breakdown strength are arranged in parallel on the surface of a P-type silicon substrate 13. The FET 30 has a gate electrode 2 formed on the surface of the substrate 13 via a thin gate insulating film 9, source regions 3, 6, and drain regions 1, 4. The regions 3, 6 are constituted of the region 3 of relatively high concentration and the region 6 of relatively low concentration which is connected with the channel side of the region 3. The regions 1, 4 are constituted of the region 1 of relatively high concentration and the region 4 connected with the peripheral part of an impurity region 1. Since the region 4 is not formed in the vicinity of a short side of the region 1, a PN junction region of the region 4 and the substrate 13 is constituted. Thus the resistance to surge can be improved, since the following are formed on the peripheral part of the region 1; the region 4 which can increase the breakdown strength of drain region by relieving electric field, and the region which can increase the junction capacitance of the regions 1, 4 and the substrate 13.

Title: Method for hot rolling titanium clad steel sheet
Inventor: YAMAMOTO AKIO
IPC: B23K20/04
Filed: 1990-09-12
Abstract: PURPOSE:To stably manufacture the titanium clad thin steel sheet with high jointing strength by making a drafting interval within 30sec. at or 750 deg.C, in the process for hot rolling titanium clad steel sheet. CONSTITUTION:The titanium clad assembled slab consisting of a steel base material, and a titanium or titanium alloy laminated material is worked to the hot rolled steel sheet by plural times of rolling reduction. In this case, the interval of rolling reduction pass on the rolling at over than 750 deg.C or over is regulated to 30sec. Consequently, the interface metallic compound layer is restricted from increasing, and the metallic compound of bitten state can be prevented from generating. Therefore, the thin steel sheet of titanium clad steel is manufactured with the same equipment and process as that of usual steel production. Further, the thickness of the interface metallic compound is thin and the metallic compound layer of bitten state is removed, so the deterioration of the quality as the clad steel sheet as well as the joining property are not generated.

Title: Varistor
Inventor: TAIRA HIROAKI
IPC: H01C7/10
Filed: 1990-09-11
Abstract: PURPOSE:To obtain varistors which can save manufacture cost as well as electrostatic capacitance and improve surge strength without increase in electrode area by making the interelectrode distance between the outer peripheral edge of an inner electrode and a surface electrode wider than the central interelectrode distance by a specific value or more. CONSTITUTION:This varistor 1 keeps the interelectrode distance (t) between the outer peripheral edge 8a of an inner electrode 3 and a surface electrode 4 wider than the interelectrode distance (t') between the center 8b of the inner electrode 3 and the surface electrode 4 where the t/t' ratio of both electrode distances is 1.05 or more. This makes the outer peripheral edge 8a of the inner electrode 3 curved inward. As a result, in the case of impressing a surge current above the effectual value, lines of electric force are not concentrated on the outer peripheral edge of the inner electrode, but dispersed uniformly almost throughout the inner electrode, so that surge strength can be improved without increase in electrode area. In addition, the manufacture cost can be saved by reducing use of noble metals, and application can also be enlarged by use for high-frequency signal lines and decreasing electrostatic capacitance.

IPC: F16H25/24
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To prevent deflection and natural vibration of a driving spindle by arranging a flexible tranction means so as to generate dependent relation between spindle support units and slide assembly. SOLUTION: Spindle support units 271 , 291 are guided by a guide rail 3, and connected to each other by flexible paired connection means 31. A traction cable 31' between the units 271 and 291 movably passes through a slide assembly 9. When the assembly 9 is moved leftward due to rotation of a driving spindle 13 and struck against the unit 271 , it pushes the unit 271 and the unit 291 follows the unit 271 with a maximum spacing. When the assembly 9 reaches a left end of a guide base 1, the unit 271 is in contact with a buffering device. A traction cable 31'' applies stopping traction force to the unit 291 . It is thus possible to avoid deflection and natural vibration of the driving spindle 13 even when the assembly 9 is arranged near an end of the base 1.
