Title: Production of thin film magnetic head
Inventor: OUCHI HIROYUKI
IPC: G11B5/39
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To improve the production yield without deterioration in characteristics by removing an unnecessary part of a gap layer formed on a lower magnetic pole layer and a first insulating layer, then forming a coil and insulating layers in the required number' of layers, and forming an upper magnetic pole layer. SOLUTION: A first insulating layer 3 is formed by applying a resist on a lower magnetic pole layer 2 so that the APEX part 15 near the gap is formed together. A gap layer 4 is formed as a thin film all over the layer 3 and then removed except for the necessary gap part and the APEX part 15. A coil 5 is formed as a conductive thin film on the layer 3, and second and third insulating layers 6, 8 are formed on the coil 5. An upper magnetic pole layer 13 is formed as the uppermost part, and an Al2 O3 gap layer 4 is formed to cover the APEX part 15 to avoid such problems that the magnetic pole layer 13 intrudes through cracks caused by rehardening in the APEX part comprising a resin. Thus, intrusion of the magnetic pole layer through cracks is prevented during the pole layer is formed.

Filed: 1988-04-15
Abstract: PURPOSE:To detect the center of gravity of the electrode part by making an optical scan within a scanning range, detecting the total number of picture elements of the electrode part which has brightness exceeding a set level and finding an X-directional and a Y-directional line bisecting having all the picture elements equally. CONSTITUTION:The optical scan is made within the scanning range A at constant pitch in an X direction and the total number S=n1+n2+...+nM of picture elements of the electrode part P having the brightness exceeding the set level is found. Then a scan is made again in the X direction and the coordinate YG of the line N1 which halves the said total number S of picture elements equally is found. Similarly, an optical scan is made in the Y direction and the coordinate XG of the line N2 which halves the total number S equally is found to detect the intersection of both lines N1 and N2, i.e. the center GP of gravity of the electrode part P. Thus, the center GP of gravity of one electrode part P is detected and the center GQ of gravity of the other electrode part Q is also detected.

Title: Device for measuring vibration
Inventor: TAI SHIYUUICHI
IPC: G01H9/00
Filed: 1980-07-09
Abstract: PURPOSE:To enhance the reliability in measurement by sensing the reflected light from the reflecting surface of a weight supported by an object to be measured via elastic bodies. CONSTITUTION:Light is guided to a vibrating sensor fixed to the object to be measured via an optical fiber and inputted to the self reflecting surfaces 4a and 4b of the weight 4 supported by springs 3a and 3b, via a half mirror 8 and a mirror 9. The reflected light is inputted to optical fibers 12a and 12b via rod lenses 10a and 11a. When the weight 4 receives the vibration in the X direction to which, e.g., the spring 3b is expanded and contracted, the amount of light incident to the optical fiber 12a varies in response to the vibration period. Likewise, the amount of the incident light to the optical fiber 12b changes with the vibration of the expanding and contracting (Y) direction of the spring 3a. With respect to the vibration in the arbitrary direction, the amount of the incident light to the optical fibers 12a and 12b varies with the vibration components in the X and Y directions. Since the external electromagnetic effects are not affected, the reliability in measurement can be enhanced.

Title: Image recording device
Inventor: KANEMITSU SHINJI
IPC: B41J15/16
Filed: 1989-04-13
Abstract: PURPOSE:To prevent deterioration of an image quality if a recording paper is transported only by a traction feed system with a tension maintained at an image recording section by setting the feed amount of the traction feed system at a recording length +- a pixel pitch for a recording length after the paper comes out of a roller. CONSTITUTION:A recording paper 5 is fed onto a platen plate 2 by a pair of fixed quantity feed rollers 1, 1', then it is given tension by tension rollers 3, 3' which sandwich the paper. As a result the paper sticks to the surface of a platen plate 2 tightly. The record-, ing paper 5 stops, then an ink jet head 4 moves and an image is recorded on the paper fed by a fixed width. Next, the fixed quantity feed rollers 1, 1' feed the paper 5 to an image recording section by a fixed feed amount. Then the new part recording material 5 is positioned on the platen plate 2. Even after the rear end of the recording material 5 passes through the fixed amount feed roller 1,1' completely, the tension rollers 3, 3' are driven under the same drive state to transport the paper 5 to the surface of a platen. Thus it is possible to record an image up to the rear end of the paper 5.

Title: Time base correcting device for reproducing composite video signal
Inventor: IMAMURA OSAMU
IPC: H04N9/68
Filed: 1988-04-19
Abstract: PURPOSE:To prevent the dynamic range of a phase comparator from being dislocated at the operating point of a burst signal loop by detecting the allowing operation range over of the operating point in the burst signal loop, controlling the gain of the burst signal loop and setting the operating point in the allowing operation range. CONSTITUTION:During a high level period on the logic of a level detecting means 13 output, a gain control means 14 causes the gain of the burst signal loop to go up by several dB higher than the regular gain and fluctuates the operating point with slightly generating oscillation. Then, when the output of the level detecting means 13 goes to be a low level on the logic, the gain is returned to be the regular gain. When the output of the level detecting means 13 goes to be the high level, the regular gain of the burst signal loop is momentaneously decreased by tens dB. Then, when a constant time passes after such a condition is obtained, the gain is gradually increased so as to be the regular gain. Thus, the allowing operation range over of the operating point in the burst signal loop is detected and the gain of the loop is controlled by a detecting signal. Then, the operating point can be set in the allowing operation range.

IPC: G01N33/577
Filed: 1993-03-31
Abstract: PURPOSE:To facilitate detection of a single-stranded DNA by subjecting an extraphysiologic preparation to acid treatment in order to hydrolyze a damaged DNA selectively and then treating the preparation with an antibody of the single-stranded DNA for the purpose of morphological observation. CONSTITUTION:A normal formalin section of extraphysiologic preparation, a suspension of tissue cell, or the like is employed as a specimen. The hydrolysis is effected under conditions of a specified temperature and time while diluting hydrochloric acid or sulfuric acid. Consequently, damaged cell nucleus DNA is hydrolyzed preferentially to produce a single-stranded DNA which is then treated with an anti-single-stranded DNA antibody. Distribution of antibody is then observed in a tissue sample thus obtained through microscopic examination. In this regard, the morphological observation can be facilitated using an antibody labeled with a pigment, e.g. rhodamine, or a fluorescent pigment.
