Title: Manufacture of surface acoustic wave device
Inventor: MATSUI ATSUSHI
IPC: H03H9/08
Filed: 1985-07-02
Abstract: PURPOSE:To decrease the variance in the center frequency by providing a chip pattern to a photo mask and a sensing pattern and a probing pattern onto a scribe line, transferring them onto a wafer vapor-deposited with electrode metal and applying etching while measuring an electric resistance between the probing patterns. CONSTITUTION:The photo mask is provided with the chip pattern 2, the sensing pattern 4 and the probing pattern 5, and they are transferred to the wafer 1. Then a measuring terminal is contacted with the probing pattern 5 of the wafer 1 to apply etching while measuring the electric resistance. As the film thickness (h) and the electrode width (w) of the interdigital electrode 6 increase, the propagation velocity Vs is decreased. On the other hand, the electric resistance R of the pattern 4 is proportional to the width (w) and the thickness (h). Since the wire width of the pattern 4 is formed nearly the same as the wire with the interdigital electrode 6, the variance in the center frequency produced by the film thickness decided at the vapor-deposition of the electrode and the line width decided at the etching is decreased by applying etching while measuring the electric resistance between the patterns 4.

Title: Magnetic disk device
Inventor: SAKABE TETSUYA
IPC: G11B21/10
Filed: 1986-06-20
Abstract: PURPOSE:To quickly position a magnetic head to an accurate position by generating a position drive signal in the timing delayed by a prescribed time at the point of time when a difference amount is zero so as to minimize the vibration of the magnetic head and the overshooting amount of positioning. CONSTITUTION:A position driving signal generating section 50 is provided, which generates a PSDR signal (7) generated by a difference zero signal (5)when the mode transition is moved from the DRIM mode to the PSDR mode in the timing delayed by a prescribed time from the point of time when the ON of the difference zero signal (5) is detected. Thus, the vibration of the magnetic head caused by tentative discontinuity of a drive current conducted through a VCM generated at the transition into the PSDR mode and the positioning overshoot are minimized to position the magnetic head quickly to an accurate position.

Title: Voltage detection circuit
Inventor: OOKUBO ATSUSHI
IPC: H02P29/00
Filed: 1977-12-05
Abstract: PURPOSE: To operate an electrode brake despite the remaining of damped AC voltage, by detecting that the damped AC voltage reaches a predetermined level after a power switch for a motor is turned off.  
     CONSTITUTION: When the detected AC voltage is applied to input terminals IN, the terminal voltage of a resistor R2 and the base voltage of a transsistor T1 have wave forms as shown in Fig. Since the transistor T1 remains off before a time Tc, the terminal voltage of a capacitor C is higher than the Zener voltage of a constant voltage diode ZD2 and this diode remains on and supplies an output signal to output terminals OUT. Since the terminal voltage of the capacitor C is lower than the Zener voltage of the diode ZD2 after the time Tc, the diode remains off and supplies no output signal to the output terminals OUT. A predetermined level of increasing DC voltage can be detected on the ground of the state change of the diode ZD2.
