Title: Composite type head
Inventor: TAKITA KUNIO
IPC: G11B5/265
Filed: 1987-02-26
Abstract: PURPOSE:To assure a distance for magnetical sepn. of an R/W head and E head by diagonally providing notches to the angle parts of center cores where both heads face each other. CONSTITUTION:The R/W center core 6 of the R/W 2 is diagonally notched 20 to the angle part opposite to the E head 3. The E center core 11 of the E head 3 is diagonally notched 21 in the angle part opposite to the R/W head 2. Then, the distance to magnetically separate the R/W head and the E head from each other is formed between the notches 20 and 21 and is formed not in the track direction as with the conventional head but in the diagonal direction. Increase of the thickness of both or either of the R/W center core and the E center core is thereby permitted and the sectional area of the center cores is widened. The composite head which substantially prevents generation of magnetic saturation and has good performance is thus obtd.

Title: Method for deflection correction of electron beam at electron beam lithography equipment
Inventor: KAGA HIROYASU
IPC: H01L21/66
Filed: 1990-02-23
Abstract: PURPOSE:To shorten the time required for a mode change operation by a method wherein a correction factor is computed by the measured value of a deflection distortion by using a deflection correction table of a reference mode on the basis of an absolute calibration result of the reference mode. CONSTITUTION:An electron beam 1 is deflected by an electromagnetic deflection MD 8 whose deflection aberration is small and by an electrostatic deflection SD 9 whose deflection response is fast. When individual beam deflection correction amounts for the MD 8 and the SU 9 are mixed properly, it can be deflected with good accuracy. A conversion factor is input to a mode correction table 16 of electrostatic deflection. At the same time, a conversion factor of the electromagnetic conversion is input to a mode correction table 17. Thereby, since the correction factor between modes can be found simply, the time required for a correction operation can be finished in a short time.

Title: Control method and device of hydraulic elevator
Inventor: HATANO KAZUHIRO
IPC: B66B1/26
Filed: 1993-03-04
Abstract: PURPOSE:To stabilize a running characteristic by compensating a pressure so that a pressure on the primary side can nearly match the pressure on the secondary side in the start time of a hydraulic elevator and controlling it by switching the control to a speed feed back control after starting. CONSTITUTION:In the start of a hydraulic elevator, a pressure on the hydraulic pump 8 side (primary side) can be compensated so as to be raised nearly upto the pressure on the hydraulic jack 2 side (secondary side). After the start of the hydraulic elevator, the control is carried out after being switched from a pressure compensation to a speed feed back control. Therefore, as the flow rate of a pressurized oil flowing in the hydraulic jack 2 is controlled, a speed control device 13 is put into practice easily under simple constitution, even when the speed feed back control is carried out in the whole running area. Thereby, stable running characteristic can be always given.

IPC: G01R31/319
Filed: 1991-03-08
Abstract: PURPOSE:To maintain the temperature of a semiconductor chip at a fixed value, and to inhibit the variation in the delay time of a circuit by using a gate array LSI of low power consumption type, provided with a dummy circuit, and by operating it at a frequency differentially varied to the operational frequency of a waveform generator as well as a strobe pulse generator. CONSTITUTION:A dummy circuit 9 is provided in a semiconductor chip of an LSI, the main circuit of which is formed out of a waveform generator 3, a strobe generator 7 and a logic comparator 8. A signal PCLK, the frequency of which is differentially varied to the frequency of a timing signal DB given to the maim circuit, is given to the circuit 9. When the signal DB is changed from a frequency f1 to f2 (f1<f2), the frequency of the signal PCLK is differentially changed from f2 to f1. In this way, the power consumption of the main circuit as well as of the dummy circuit 9 is maintained at a fixed level on the whole regardless of the variation in frequency, and the variation in the delay time of the waveform generator 3 as well as of the generator 7 following the temperature increase of the semiconductor chip is thus prevented.

In this case, a first side wall 1c is a comparatively low one which is roughly equal to height of a ski, and a second side wall 1d is formed so as to be deviated to the outside by a portion of a stepped part 1f from a first side wall 1c and consideration is made so that the surface of the outside of glider's ski boots does not come into contact therewith. In such a way, an area of the ski track 1, and also, a cross-sectional area of the snow surface to be put out of the way by a step pressure sled 6 can be decreased by a portion of a step difference of a first side wall 1c and a second side wall 1d, and a tractive resistance of the step pressure sled 6 by a snowmobile is reduced. Accordingly, the ski track 1 can be formed by a small sized snowmobile.

Title: Assembling method for frame and face plate for wooden panel
Inventor: SEWA MUTSUO
IPC: B30B15/30
Filed: 1990-02-23
Abstract: PURPOSE:To improve workability and the quality of a panel by a method wherein the periphery of a frame is held by holding plate parts disposed at the fore, rear, right and left parts of the frame in such a manner that the holding plate parts press the frame toward the inside thereof, a face plate is pressed against the upper surface of the frame by a press platen to be bonded to the frame. CONSTITUTION:In the assembly work of a frame and a face plate, the frame 3 set on a horizontal table 12a is held by holding plate parts 12h, 12o so that the periphery of the frame is pressed therebetween, and the frame is strongly made into one body with the face plate by a press platen 14A which presses the face plate 5 against the upper surface of frame. In the pressing process by the press platen, the frame is not caused to break even when it is pressed by the press platen because the periphery of the frame is strongly pressed and held by the holding plate parts constituting a hold mechanism. Accordingly, this makes it possible to mechanize the joining work of the frame to the facing plate, and the workability of manufacturing a panel and the quality of the panel can be enhanced.

Title: Semiconductor recording system
Inventor: SAWAZAKI KENICHI
IPC: H01L29/788
Filed: 1979-04-13
Abstract: PURPOSE: To attain high-density recording by obtaining a recording medium by forming an electret material film on a semiconductor substrate, and then by injecting electric charge by relatively scanning a scanning electrode on this recording medium.  
     CONSTITUTION: In n-type silicon semiconductor substrate 11, p-type impurity layers 12 and 13 are formed by diffusing and on the surface of substrate 11 between layers 12 and 13, electret material film 14 such as "Teflon " is formed, thereby constituting recording medium 10. The injection of charge by applying a signal voltage between recording head 16 on material film 14 and substrate 11 forms a depletion layer in substrate 11 right under material film 14 and a channel between impurity layers 12 and 13. To reproduce the thus recorded signal, fixed read voltage VR is applied between head 17 and electrode 15 on layer 13 while reproducing head 17 on layer 12 is relatively moved. When head 17 passes by the channel part of substrate 11, a current flows between layers 12 and 13, and consequently output signal VOUT is obtained. This method makes high-density recording possible even when the track width is narrow.
