Title: Dc-stabilized power supply
Inventor: YAMAGUCHI ATSUSHI
IPC: G03G21/00
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a DC-stabilized power supply wherein its stable output can be obtained over a region of its load varying therein, even if it is of a constitution in which the sensing accuracy of its input current is poor. SOLUTION: An input-current sensing circuit 420 senses the AC current fed from a commercial AC power supply 100. An input-voltage sensing circuit 430 senses a rippled voltage which is obtained by rectifying the AC voltage fed from the commercial AC power supply 100 through bridged diodes 401. An overall equipment controlling circuit 80 predicts the load current required by a load RL. A switching-pulse generating circuit 410 outputs pulse signals to a switching FET 405, based on the input current signal sensed by the input- current sensing circuit 420, the input voltage signal sensed by the input-voltage sensing circuit 430, and the load current signal predicted by the overall equipment control circuit 80.

Title: Working method for magnetic disk and magnetic disk as well as magnetic disk device
Inventor: SAITO SHIGEYOSHI
IPC: G11B5/84
Filed: 1989-12-22
Abstract: PURPOSE:To prevent the degradation in the positioning accuracy which occurs in scratches, etc., by intersecting the working loci in the surface working of at least either of disk blank and a magnetic material film with a concentrical region. CONSTITUTION:While working tools 27, 28 are moved radially, the tools are pressed to a rotating magnetic disk 4 to work the disk in the spiral loci or while the magnetic disk 4 or the disk blank is rotated eccentrically from the center of rotation (the center of the concentrical region), the working tools 27, 28 are pressed to the disk or blank to deviate the working loci, by which the working loci are intersected with the concentrical region. The ratio of the rotating speed V2 of the magnetic disk 4, etc., and the feed speed V1 of the tools in the diametral direction or the eccentricity of the magnetic disk 4 at the time of working is controlled to a desired value. The degradation in the positioning accuracy occurring in the scratches unavoidably generated at the time of working and the reliability of the recording and reproducing operations of data is surely prevented in this way.

Title: Synchronous device of transmission
Inventor: AIKAWA HIROSHI
IPC: F16D23/06
Filed: 1992-11-18
Abstract: PURPOSE:To reduce the number of parts and simplify assembly work by making constitution in which a key spring presses a synchronizer ring cone surface against a speed shift gear cone surface by means of the slide of a sleeve and a sleeve spline tooth meshes with a speed shift gear clutch tooth. CONSTITUTION:When a sleeve 43 is shifted from a neutral position toward a speed change gear 32, it slides axially in regard to a clutch hub 40, and a key spring 52 that is engaged with the groove 45 of the sleeve 43 is also moved, so it presses the inner cone surface 49 of a synchronizer ring 48 against the outer cone surface 47 of the speed change gear 32. Synchronous operation is started due to friction between the ring 48 and the speed change gear 43 with an opening amount phase difference between the ring 48 and the clutch hub 40 kept generated. When the sleeve 43 is moved further, the movement of the spring 52 is deterred by means of the ring 48, and the engagement of the spring 52 and the groove 45 is disengaged, and synchronism is accelerated. When rotary difference is removed, the inner spline tooth 44 to the sleeve 43 meshes with the clutch tooth 46 of the speed change gear 32. As a result, structure can be simplified.

Title: Programmable logic element with long line wiring of excellent test performance
Inventor: YAMANAKA AKIRA
IPC: H03K19/173
Filed: 1990-11-30
Abstract: PURPOSE:To reduce the time required for testing a long line by terminating an end of the long line being one side of a programmable logic element to a programmable logic element except a corner of a programmable logic element of other side adjacent to the above one side. CONSTITUTION:An end of a long line 13 arranged to a circumference of a programmable logic element 11 is connected to a switch station 15 except corners 15-3, 15-4 of other side adjacent to one side of a programmable logic element to which the long line 13 belongs. Thus, the concentration of the corners at the end of the long line 13 onto the station 15 is avoided and the end of the long line 13 is dispersed to other station 15 without causing hindrance to the supply of a common signal. Thus, lots of long lines 13 are tested simultaneously at the test of a long line 13 and not only a broken wire but also inter- wiring short-circuit is simultaneously tested. Thus, the time for requiring the circuit test is reduced.
