Title: Tape travelling controller
Inventor: YAMAMOTO RYOHEI
IPC: G11B15/467
Filed: 1991-04-19
Abstract: PURPOSE:To stably travel a magnetic tape even in the transient condition to change from a standard travelling speed to a fast travelling speed. CONSTITUTION:The control voltage outputted by a controller 15 is inputted to a driver 9 through a switch 18 and a motor 10 is driven. Thus, a take-up reel 3 is rotated and a magnetic tape 20 is wound. An FG 13 generates a pulse synchronized with the rotation of the motor 10 and the pulse is detected by a Hall element 14. The controller 15 loads a servo so that the interval between the detecting pulses can be coincident with the prescribed reference value. A controller 8 measures the interval between the output pulses of pulse generators 4 and 5 and outputs the control voltage corresponding to the error between the measured value and the reference value. A comparator 17 compares the control voltage outputted by controllers 8 and 15 and switches the switch 18 in correspondence to the compared result.

Title: Forming method of wheel rim
Inventor: KAMAHORI HIDEYA
IPC: B21D7/08
Filed: 1984-06-07
Abstract: PURPOSE:To improve the deflection accuracy of a rim by executing initial forming by approaching both forming rolls at a very low speed, and subsequently, approaching both the forming rolls at a high speed. CONSTITUTION:When a work 22 is installed onto a bottom roll 9, a servovalve 30 is operated by a signal of an electronic control unit 35, and the hydraulic pressure is supplied to a cylinder chamber 14a. Therefore, the roll 9 rises at a high speed, and when the work 22 contacts an upper roll 8, it is decelerated to a very low speed of 0-10mm./sec by a signal of a potentiometer 34. The roll 9 which is rising at a very low speed executes initial forming of the work 22 between the roll 8 and itself. Subsequently, the regular forming is executed by controlling the valve 30 and accelerating the rising speed of the roll 9. According to this method, the centering accuracy of the work is raised, and accordingly, the deflection accuracy of a rim is improved.

Abstract: PURPOSE:To obtain a thin film head superior in corrosion resistance and mechanical strength even if a thick conductor in an electrode part is formed in the electro-forming method, by using an inorganic insulator or a metal having a low hydrogen deposition potential as shielding materials. CONSTITUTION:A head element is formed on a ceramic substrate, and an electrode part leading-out conductor 9 and the first protection film 10 are formed in the electrode part. After a foundation film 11 for power supply is accumulated, cromium which is a metal having a low hydrogen generating potential is accumulated by sputtering for the purpose of protecting the part where deposition is unnecessary to form a shielding film 17.
