Title: Magnetic recording medium
Inventor: KANAZAWA MINORU
IPC: G11B5/738
Filed: 1989-09-25
Abstract: PURPOSE:To obtain a thin metal film type magnetic recording medium having an excellent traveling durability and particularly showing improvement in head contamination by providing a base coating layer essentially comprising a binder and aggregates having specified distribution density and particle size on the surface of a nonmagnetic supporting body on which a magnetic layer is formed. CONSTITUTION:A base coating layer essentially comprising a binder and aggregates is provided on the surface of a nonmagnetic supporting body on which magnetic layer is formed. The aggregates are dispersed in the base coating layer by 10<2>-10<7> particles/mm<2> density and each contains 2-10 particles of 10-50 mmu particle size gathering two-dimensionally. When a film is formed on the base layer on the nonmagnetic supporting body by vapor deposition, metal atoms for deposite grow on the aggregates as cores to form fine projections on the magnetic layer. These fine projections are composed of columnar crystalline of metal which are the grown state of the deposited metal atoms. The surface of the fine projections is made properly rough to give smooth contact with a head. Thereby, traveling durability of the medium can be improved and the obtd. medium is excellent in terms of contamination and clogging of head.

Title: Device for measuring length of plate of slitter line
Inventor: ABE TOMOHIDE
IPC: G01B21/06
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for holding length measurement data using an auxiliary power supply during power interruption. SOLUTION: An analog computing circuit which sets the initial diameter D0 of a roll on which the steel plate of a slitter line is wound, before the steel plate is drawn out, sets the plate thickness θ, and detects the current roll diameter D while the steel plate is being drawn out of the roll, and which consists of amplifiers 1, 4 with a gain of -√π, a squaring multiplier 2, pentapole inverted amplifiers 3, 6 and a divider 7 to perform the operation of (D0 <2> -D<2> )π/ϕ, detects the overall length of the steel plate drawn out of the roll. Since this measuring device is of an analog type, even in the event of a power failure the overall length data is immediately output from the computing circuit on power restoration.  Since the slitter line does not require the overall length data during power interruption, the length measuring device can be said to be of an outage-guaranteed type that operates by restoring power.

Title: Audio signal recording and reproducing device
Inventor: YAMAMOTO NAOKI
IPC: H04N5/91
Filed: 1990-09-18
Abstract: PURPOSE:To easily switch the mode at the time of reproducing an audio multiple signal by outputting first and second audio signals at the time of obtaining a identification signal indicating stereo signals and selecting either output except in the case of stereo signals. CONSTITUTION:When audio signals are recorded by a discrimination signal processing means 22, the discrimination signal indicating whether first and second audio signals a1 and a2 are stereo signals or not is recorded on a recording medium 5 together with recording signals. At the time of signal reproducing, first and second audio signals b1 and b2 are reproduced by reproduced signal processing parts 6 and 7, and the identification signal is simultaneously reproduced by a discrimination signal reproducing means 23. First and second switch means 8 and 9 are controlled based on this discrimination signal b1 and a mode control signal (c), and first and second audio reproduced signals b1 and b2 are outputted as they are in the case of stereo signals; but otherwise, only the first or second reproduced signal b1 or b2 is simultaneously outputted from switch means 8 and 9 or first and second audio reproduced signals b1 and b2 are outputted. Thus, the mode is switched very easily.

Title: Production of semiconductor pressure sensor
Inventor: AOKI KENICHI
IPC: G01L9/00
Filed: 1992-09-18
Abstract: PURPOSE:To reduce the number of working processes and to enhance workability, yield and reliability by anodically bonding a sensor substrate and a support member and etching the sensor substrate using the support member as a musk material to form a thin film part. CONSTITUTION:A sensor substrate 1 having gauge elements 7 formed thereon and a support member 2 having a through-hole 5 are bonded by anodic bonding. The support member 2 and the through-hole 5 are used as a mask and the sensor substrate 1 is etched to form a membrane part to produce a pressure sensor. Since the support member is used as the mask, it becomes unnecessary to perform a photolithographic process and the number of processes can be reduced. Since the sensor substrate 1 and the support member 2 are bonded at first, strength, workability and yield are enhanced. The reliability of a bonded part is enhanced because of the anodic bonding.
