Inventor: ASHIKAGA TADASHI
IPC: H02P29/00
Filed: 1989-07-10
Abstract: PURPOSE:To obtain a high torque by a method wherein 120 deg. square wave is produced by a minimum air gap position detecting signal and the maximum exciting point is set near the point of 60 deg. before the maximum exciting point. CONSTITUTION:The optimum driving of a variable air gap motor is effected by a speed command and a 120 deg. square wave, obtained by amplifying the output of a speed detector through a PI amplifier to obtain a torque command and inputting it into a control circuit CNT. The control circuit CNT obtaine a minimum air gap position signal GC employing 6 sets of position detectors PS and converts it into a driving current phase command through a converter T. An exciting phase angle is determined by setting the maximum exciting point at the center of the square wave to a point near 60 deg. before generating the minimum air gap position.

Filed: 1994-07-28
Abstract: PURPOSE:To make it possible to deaden the impact noise when a drawer is stopped at the ends of the back and forth movement, by using simple mechanism. CONSTITUTION:A rail 5 having a pipe-like shape with closed front and rear ends in which a piston 6 attached to a drawer 3 through a connector 7 can slidably be fitted, is arranged parallelly to the direction of the movement of the drawer 3.

Filed: 1992-07-03
Abstract: PURPOSE:To erase a video signal used to scan a part at the outside of a screen by applying a vertical synchronizing signal for driving a vertical deflection circuit and a video signal for driving a CRT transmission to the circuit and the CRT while being delayed in the case of magnification display so as to generate a vertical blanking pulse at a same phase as that of a received video signal. CONSTITUTION:A synchronizing signal separated from a video signal by a synchronizing separator circuit 1 is fed to a vertical blanking pulse generating circuit 2, from which a vertical blanking pulse is generated. When the screen is displayed with magnification, the vertical synchronizing signal is fed to a vertical deflection circuit 4 while being delayed for a period corresponding to a time for scanning a part at the outside of the screen at a phase delay circuit 3. The video signal is delayed by the same time at a video signal delay circuit 5 and the delayed signal is used to drive the CRT. Thus, an electron beam scanning at the outside of the screen is erased and the effect by secondary electrons is eliminated.

Filed: 1984-08-27
Abstract: PURPOSE:To facilitate replacing a cleaning member and to make replaceable parts inexpensive by setting the cleaning member attachably and detachably to a guide provided in parallel with the axis of a carrier which carries forms. CONSTITUTION:A brush 18 and its attaching part 18a are set attachably and detachably to a rail 17a parallel with the axis of resist rolls 16 which carry forms to the side of a photosensitive body, and paper powder or the like stuck to an upper roll 16a is removed. If the brush 18 is deformed and defects of contacting occur because the brush 18 is used repeatedly for a long period, the attaching part 18a is slided to replace the brush with a fresh brush. Thus, the replacing work is easy, and the expense is reduced because replaced parts are only the brush 18 and the attaching part 18a.

Title: Bubble memory tester
Inventor: HIRATA KANEMI
IPC: G11C11/14
Filed: 1983-09-27
Abstract: PURPOSE:To shorten sharply a rise time suitable for a manufacturing spot and to reduce a production cost and to enable the titled bubble memory tester to be used also for experiment and characteristic measuring by limiting the kind of apparatus to be used, fixing the sequence of tests, but changing data for test conditions in each test. CONSTITUTION:An output read out from a bubble memory 30 is detected by a bubble detecting part 23 and compared and decided with a write data pattern by a comparing and deciding part 24 and the result is sent to a control part 13. If the result is valid, the control part 13 advances the sequence data, reads out the succeeding test conditions from a test condition storage part 16 or the like and sets up the conditions in a program power source 17 and a timing generator 20 to drive a bubble memory 30. Since the bubble memory tester is exclusively used for only one kind of apparatus, data such as sequence data, write/read data and a data pattern are fixed data, but current values of respective gates and the test conditions can be varied. Consequently, the critical conditions of a bubble memory to be tested are searched out.
