Title: Manufacture of thin-film magnetic head
Inventor: SAWADA SHUICHI
IPC: G11B5/31
Filed: 1988-02-19
Abstract: PURPOSE:To sharply improve the packing density of a thin-film magnetic head by covering the base plate of the head with a patterned resist except the sections where recessed sections are to be formed and heating the base plate in such a way that the average slope of the side face at the end section of the resist attain a specific angle, and then, forming the recessed section by ion beam etching by using the resist flowing from the resist cover as a mask. CONSTITUTION:The surface of a base plate 60 is covered with a patterned resist 62 except the sections where recessed sections 63 are to be formed and the base plate 60 is heated in such a way that the average slope of the side face at the end section of the patterned resist 62 can become an angle of <=70 deg.. Then the recessed sections 63 are formed on the surface of the base plate 60 by using the flowing resist 62 as a mask. After forming the recessed sections, the remaining resist is removed. When such procedures are adopted, recessed section with side wall surfaces of smooth slopes can be formed easily on the base plate and magnetic fluxes are gradually squeezed toward the leading end of a pole by means of the slopes. Therefore, the packing density of this head is improved, because the maximum magnetic flux density is produced at the leading end of the pole and leakage of magnetic fields is reduced.

Filed: 1986-02-21
Abstract: PURPOSE:To facilitate the confirmation of normal operation, by starting the soft counter in a microcomputer having a time measuring exclusive program immediately after the release of resetting and comparing the count value of a counter with a predetermined value at the time of the next resetting. CONSTITUTION:A microcomputer 3 has a program only for time measuring. An input signal is applied to one-shot circuit 2 through a differentiator 1 and the output thereof is applied to the reset terminal of the computer 3 to reset the soft counter in the microcomputer 3 at the change point of the input signal. The soft counter is started immediately after the release of resetting and the count value of the counter is compared with a predetermined set value at the time of the next resetting. The signal corresponding to the magnitude thereof is outputted to the outside. On the basis of this output, it can be discriminated whether the cycle of the input signal is equal to, more than or less than a definite value.

Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide structure and method for getting reformed ESD resistance by forming a double layer including the second layer of growth silicon only on the related region of the circuit element of SOI to raise ESD resistance. SOLUTION: For a substrate such as a wafer 10 or the like which has a buried oxide layer 12 to separate a bulk substrate 14 and a surface silicon film 16, an isolating dielectric layer 18 is made on a buried oxide layer 12 first so as to separate the regions 20 and 22. Next, silicon or polysilicon is added to the desired position on the wafer 10. The double layer of the silicon of SOI or SOS structure enables many device features, and in case of MOSFET, the junction is deepened, and the series resistance of the main body is lowered to get transistor structure where ESD resistance is improved. In case of a reduced-coupling capacitor, the series resistance of the electrode is lowered to get an electronic switch MOSFET having ESD resistance.

Abstract: PURPOSE:To enable the arbitrarily variation in the length of a starting end of a lead wire of a coil with a simple mechanism by providing a plurality of pins telescopically of the same direction as a winding frame mounting direction at the peripheral edge of a winding frame securing plate. CONSTITUTION:A pin 15 which engaes a wire 9 is telescopically provided at a winding frame securing plate 8.

When a winding frame 7 is initially rotated once, a magnet wire 9 is engaged with the pin 15. When the coil is removed from the frame 7 after the entire coil is wound, the length of the starting end of the lead wire extends in the longest length. When the length of the starting end of the lead wire of the coil is reduced in the shortest length, the pin 15 is pushed in leftward direction. In this state the wire 9 is not engaged with the pin 15 but is wound directly from a clamp 10 on the frame 7.
