Title: Polishing of magnetic head
Inventor: YASUDA KYOSUKE
IPC: B24B19/26
Filed: 1987-01-20
Abstract: PURPOSE:To permit the high speed polishing of a magnetic head by installing a flexible disc-shaped polishing sheet, revolution drive part, straightening plate for generating an air stream and revolving the polishing sheet at a high speed and floating-up-revolving the polishing sheet for the straightening plate. CONSTITUTION:When a polishing sheet 1 is revolved by a motor 3, an air stream entrained by the revolution of the sheet 1 is generated in the gap part between the sheet 1 and the surface 6 of a straightening plate 2. Since the flow speed on the outer periphery is larger than that of the inner peripheral part, a low pressure is generated, and the outer peripheral part of the sheet 1 is attracted to the straightening plate 2 side, and at the same time, the air stream towards the outer peripheral part from an intake passage 7 is generated, and a force for pushing up the sheet 1 acts. In the high speed revolution, the sheet 1 floating-up-revolves under keeping a stable gap between the surface 6 of the straightening plate 2. Therefore, a magnetic head 4 is attached onto the surface of the sheet 1, and polishing is performed. Therefore, the simple constitution is obtained, and the polishing time can be reduced.

Title: Substrate fixing method for mbe sample and its apparatus
Inventor: YAJIMA KUNIMITSU
IPC: H01L21/26
Filed: 1986-01-21
Abstract: PURPOSE:To form an uniform In metal layer between a wafer holder and a wafer, and fixing the wafer on the wafer holder with excellent uniformity, by pushing up a piston, and introducing molten In metal fluid into a gap between the wafer holder and the wafer to fill the gap. CONSTITUTION:An upper and of a cylinder 9 is provided with an aperture 16, a wafer-center hole 15 to introduce an In metal fluid 2 is drilled at the center of a wafer holder 1, and a heating apparatus 5 to melt an In metal and to maintain its state is installed around a cylinder 9. The flow rate of the In can be adjusted by the lift amount of a piston 10, and the In is supplied between the wafer holder and the wafer so as to be slightly superfluous. The superfluos In metal fluid which flowed out from a gap between the wafer holder 1 and the wafer 3 drops into a groove 4, and prevents a phenomenon that the In metal scatters on the wafer surface during MBE growth. Thus the wafer is fixed on the wafer holder by the effect of the In metal.

Filed: 1991-01-31
Abstract: PURPOSE:To reduce the dimension and weight of a trailing arm when the rear part of a trailing arm is formed to a bifurcated form and one of the bifurcated shaped part is connected with a laterall link. CONSTITUTION:A trailing arm 9 extending in the longitudinal direction of a car body is constituted so as to be branched to a bifurcated form in the rear part by the first and the second link members 9a and 9b. The first link member 9a is formed integrally with lateral link 3 among three lateral links 3, 4 and 5. The second link member 9b is connected to the central part of the lateral link 4. The second link member 9b consists of an elastic member made of FRP, etc., and formed so that the thickness is gradually reduced forwardly. Accordingly, when a wheel 1 bumps, the second link member 9b is elastically deformed in the vertical direction of the car body, and the variation of the distance from the first link member 9a is permitted. Accordingly, the joint with the bifurcated branched point is rigidly performed by a bolt 9c, and the necessity of hinge joint is obviated, and the reduction of dimension and weight can be achieved by that portion.

Abstract: PROBLEM TO BE SOLVED: To rapidly and surely fix the magnetic particle indication on the surface of a work to be inspected by forming the magnetic particle indication on a defective part of a work, melting by heat the coloring paint where the binder is mixed with the pigment, and blowing the melted coloring paint on the magnetic particle indication and cooling it. SOLUTION: The magnetic particle where the pigment is adhered to the magnetic powder is diffused in the air and adhered to the surface of a magnetized work to be inspected, and the magnetic particle indication is formed on a defective part of the work. The coloring paint where the binder such as thermoplastic resin or grease is mixed with the pigment is melted by heat and blown on the magnetic particle indication and cooled to fix the magnetic particle indication to indicate the defective part on the surface of the work. The magnetic particle indication magnified to the blowing width of the coloring paint is formed, and cooled on the surface of the work to instantaneously fix the magnetic particle indication, and the defective part of the work can be clearly indicated. Because no solvent such as water is not mixed in the coloring paint, drying is unnecessary.

Title: Tape running controller
Inventor: NAKAMURA AKIRA
IPC: G11B27/19
Filed: 1987-01-20
Abstract: PURPOSE:To control tape running with high accuracy while evading the detection of an unnecessary control signal when restarting the tape running. CONSTITUTION:When the tape running speed reaches a prescribed speed, a prescribed value is set to a timer 3. The count of the timer 3 is started by a CTL pulse (pulse edge detection) supplied from a control (CTL) head 1 to a microcomputer 4 just after the setting. When the timer 3 reaches '0', a braking command is issued to a motor driving circuit 6, which stops the capstan motor 7 to stop tape running. In such a case, the tape is stopped at a position at a prescribed distance with respect to the CTL pulse from the CTL head 1 and no undesired pulse is generated at the start of tape running again. Thus, mis-count of the pulse counter 2 is evaded.

Title: Exhaust controller
Inventor: OSAKABE TETSUYA
IPC: F02B25/20
Filed: 1991-01-31
Abstract: PURPOSE:To improve the responsiveness and the precision of the operation stop position of an exhaust valve by controlling a driving source for a valve driving mechanism so that the exhaust valve is operated on the basis of the operation region of the exhaust valve at the time of the engine start. CONSTITUTION:A control unit 36 operates an actuator 21 on the start of an engine and shifts an exhaust valve to a perfect opening position or perfect closing position, and confirms the operation region of the exhaust valve at time. After the start of the engine, control is performed so that the exhaust valve is operated on the basis of the operation region of exhaust valve. Accordingly, even if the allowance of the actuator 21 of a valve driving device increases or slackness is generated on a transmission cable, the exhaust valve can be controlled in consideration of the allowance and slackness, and the precision of the stop position of the exhaust valve can be improved. Further, since the need of installing a buffer means for absorbing the allowance and slackness on the transmission mechanism of the valve driving device is obviated, the responsiveness of the exhaust valve can be improved.

Title: Liquid crystal display unit
Inventor: IWATA KATSUAKI
IPC: G09F9/35
Filed: 1978-02-03
Abstract: PURPOSE: To make unnecessary the pattern alignment of upper and lower electrode and to avoid dispersion in the contrast of displayed letters, by applying the same voltage to the entire electrode and the electrode formed on the plane other than the display letters on the segment electrode.  
     CONSTITUTION: Thin film is laminated on the upper panel glass 18 in the order of the segment electrode 20, insulation film 21, and the equi-potential electrode 22. The entire electrode 23 is formed on the lower panel glass 19. The both panel glasses 18 and 19 are bonded with the seal agent 24 and the liquid crystal 25 is sealed in the gap. Since the lower entire electrode 23 is connected to the upper entire electrode lead terminal 27 with the conductive agent 26, when a voltage is applied, the entire electrode 23 and the equi-potential electrode 22 are of the same potential. Thus, one opposing electrode 23 causes the segment electrode 20 to avoid display. Then, the pattern alignment for the upper and lower electrodes is made unnecessary and the dispersion in the contrast of the display letters can be avoided.
