Title: Magnetic head
Inventor: ISHIHARA KOZO
IPC: G11B5/23
Filed: 1987-11-16
Abstract: PURPOSE:To improve the efficiency of recording by forming a ferromagnetic metallic thin film on the bonding face of a couple of magnetic core halves made of ferromagnetic oxide and butting the ferromagnetic metallic thin films via a conductive nonmagnetic substance to form an operating gap. CONSTITUTION:The ferromagnetic metallic thin films 2a, 2b made of 'Sendust(R)' or the like are formed on the butted face of the magnetic core halves 1a, 1b forming a gap by means of sputtering. Then the operating gap is formed between the ferromagnetic metallic thin films 2a, 2b by butting the ferromagnetic metallic thin films 2a, 2b via a gap spacer 3. The gap spacer 3 is formed by sputtering Ti on one or both the ferromagnetic metallic thin films 2a, 2b. In using the magnetic head for recording, since the specific resis tance of the gap spacer is as small as 42X10<-8>OMEGAm, an eddy current is produced in applying a high-frequency magnetic field to the operating gap and the mag netic field caused by the eddy current increases the leakage magnetic flux a t the outside of the operating gap 16 resulting in improving the recording efficiency.

Title: Video doorphone
Inventor: YASUDA YASUSHI
IPC: H04N7/18
Filed: 1991-11-05
Abstract: PURPOSE:To obtain a digital signal processing circuit for preventing the drop of a power supply voltage in a transmission line and preventing the influence to be exerted upon a video signal and a sound signal by driving the circuit at a slow frequency band at the time of starting operation and suppressing current consumption. CONSTITUTION:At the time of detecting the input of an operation switch, a microcomputer 18 sets up the operation clock of a digital image processing circuit 9 to the lowest speed and raises the power supply of the circuit 9. Since the circuit 9 is driven at the slow speed, much starting current is not consumed and the sudden drop of a DC voltage can be prevented. Although a rough image having the small number of picture elements is displayed on a display device 1 at first, the operation clock is sequentially increased while properly setting up time by a timer so that the DC voltage is not suddenly dropped. Simultaneously the microcomputer 18 applies data consisting of the new number of picture elements to a memory controller in the circuit 9. Thus picture quality is gradually improved, and when a reference clock reaches the highest speed, the operation is ended.

Abstract: PURPOSE:To obtain sintered parts having good corrosion resistance by lubricating ferritic stainless steel powder then molding the powder, subjecting the molding to an oxidation treatment at and for a prescribed range of temp. and time and sintering the molding in a vacuum. CONSTITUTION:The above-mentioned stainless steel powder is lubricated by a die lubrication or powder incorporation lubrication method and is then molded. The resulted molding is subjected to the oxidation treatment in the atm. for 15min-1hr at 400-800 deg.C, more preferably 500-650 deg.C. The molding subjected to such oxidation treatment is sintered in a vacuum at >=1,050 deg.C, more preferably >=1,150 deg.C. The oxides of Cr and Fe is formed on the surface layer by subjecting the steel powder to the oxidation treatment prior to sintering in this invention. The formation of Cr2O3 enriches the concn. of Cr in the surface (<=100Angstrom ) and the films of Cr2O3 and Fe3O4 or Fe2O3 produced in the oxidation treatment suppress the evaporation of Cr in a vacuum sintering stage. As a result, the sintered parts having the good corrosion resistance are obtd.
