Title: Magnetic head and its manufacture
Inventor: ISHIJIMA NORIO
IPC: G11B5/23
Filed: 1983-08-18
Abstract: PURPOSE:To perform high-precision molding with small work deterioration by cutting at least the gap abutting part of C type cores of a magnetic head constituted by using the cores in combination by ion beam irradiation. CONSTITUTION:A magnetic material film 2 is fixed onto a nonmagnetic material substrate 1. The magnetic material film 2 is molded out of a metallic magnetic material, oxide magnetic material, amorphous magnetic material, etc. Magnetic circuit half bodes such as C type cores are worked in necessary shape on the magnetic film 2, and a work protection film 3 is stuck by being printed or vapor-deposited so as to cut and polish the abutting part of the half bodies where a gap is formed. This worked part is cut by ion bean irradiation. In this case, the work protection film 3 is for protection against the ion beam irradiation except at the worked part. The workpiece is irradiated with an ion beam which is ionized and accelerated with a voltage of serveral KV and below while, for example, gaseous argon is admitted into a vacuum, thereby forming a precise worked surface with small work deterioration.

Abstract: PURPOSE: To ensure transmission of signals even if combination of the framework and table of an electric stove is changed, by attaching a signal producing means at an upper central portion of the framework, and providing a signal detecting means at the central portion of the table to be placed on the stove.  
     CONSTITUTION: A signal producing means 12 is attached to the central portion of a framework 26 of an electric stove, and a signal detecting means 18-18' is provided also at the central portion of a table 17. With such an arrangement, magnetic flux 25 is produced by the signal producing means 12 when heat is produced by the electric stove with supply of electric current to the same. By the magnetic flux 25, an AC signal voltage is produced at a generating coil 18 of the signal detecting means, so that an NPN transistor 19 and a PNP transistor 21 cause on-off switch at the intervals of half cycle light emitting elements 22a, 22b cause emission of light also at the intervals of half cycle. Thus, since the signal producing means 12 and signal detecting means 18 are always made to oppose to each other, it is enabled to ensure reliability of power-source indicating operation.

IPC: G11B5/72
Filed: 1988-06-20
Abstract: PURPOSE:To suppress the attraction of a head and a disk at the time when the disk stops and to improve dust resistance by providing a monomolecular film of a lubricating agent having surface bondability to a contact start-stop CSS zone and providing a lubricating film which is larger in amt. than in the CSS zone to the other data area. CONSTITUTION:A Cr lubricating agent film 2, a magnetic Co alloy film 3, and a protective C film 4 are formed by a sputtering method on an Ni-P plated substrate 1. The CSS area is completely coated with the lubricating agent of a bond type and the so-called monomolecular film having no excessive unbonded lubricating agent is formed thereon. The lubricating agent of the amt. larger than in the CSS area is coated in the other data area. Since the excess lubricating agent does not exist in this way, the attraction does not arise even if the head and the disk come into contact with each other over a long period of time. The smooth start is thus possible. Since a large amt. of the lubricating agent exists in the data area of the disk during the operation of the device, the disk having the excellent dust resistance is obtd.

Filed: 1986-06-25
Abstract: PURPOSE:To improve a processing capacity by connecting an exclusive memory directly to a bus as the work memory of a microprocessor, thereby making the accesses from plural input/output devices to corresponding local memories independent of each other. CONSTITUTION:During accessing the local memory 104 by the MPU 101, when the I/O device 105 having a function of automatic reading/writing of a data accesses a memory 104, a decision circuit 103 stops the action of the MPU 101 after the ending of its W/R cycle, and shifts the occupation right to the local bus 113 from the MPU 101 to the device 105. Accordingly, the device 105 starts accessing the memory 104. During accessing the memory 104 by the device 105, when the MPU 101 executes a W/R to/from MPU exclusive memory 102, since an MPU bus 112 is occupied by the MPU 101, a W/R cycle is executed without accessing the decision circuit 103.

Abstract: PURPOSE:To achieve a fine pattern of a semiconductor layer by introducing an impurity with etching resistance against an isotropic etching to a semiconductor layer, performing isotropic etching selectively by leaving the semiconductor layer in thickness direction partially, and then eliminating a region which is left partially by isotropic etching. CONSTITUTION:When manufacturing a semiconductor device through a process for eliminating a semiconductor layer 26 on a semiconductor substrate by etching selectively, an impurity with etching resistance against isotropic etching of the semiconductor layer is introduced to the semiconductor layer 26.

Abstract: PURPOSE:To control the output voltage of an inverter device by providing a transformer for varying the output voltage of an inverter, and connecting a reactor in parallel to a load at the secondary side of the transformer, thereby varying the oscilation frequency of the inverter. CONSTITUTION:When the output frequencies of inverters 8A, 8B are set to f1(=omega1/ 2pi), f2(=omega2/2pi) in an equivalent circuit (an equivalent circuit particularly with discharging electrode groups 10A, 10B) when reactors 15A, 15B having inductances resonant with the static capacities of the electrode groups 10A, 10B, its equivalent impedance Z can be expressed if f1(=omega2/2pi) f2(=omega1/2pi) are set. If t01=omega01/2pi (=L1C1)<1/2>/2pi is set, the Z in case of f1=f01 becomes 1/R1, and the equivalent impedance becomes maximum. Accordingly, the secondary voltage of the step-up transformer 9A becomes maximum output voltage in case of f2=f02. Similarly, when f02 is the resonance frequency of the discharge electrode 10B and the reactor 15B, the secondary voltage V2 of the transformer 9B becomes maximum.
