Filed: 1985-11-14
Abstract: PURPOSE:To attain correct tracking control by closing a switch means at the output side of an oscillation means of a bias signal for a prescribed period and recording a bias signal while being superimposed on an erasure signal so as to improve the erasure rate by the erasure signal. CONSTITUTION:A pilot signal or the like is outputted from a recording signal generating circuit 1 by an instruction of a timing generating circuit 6 and recorded on a prescribed position of an AFT region of a tape 10 by heads 4A, 4B, and when the recording instruction of an erasure signal from the circuit 6 is given to the circuit 1 in this process, the erasure signal is outputted from the circuit 1 via a resistor 2. As soon as the output is given, a switch circuit 12 is closed, a bias signal of an oscillator 11 is outputted and superimposed on the erasure signal. The erasure signal superimposed with the bias signal is recorded efficiently to improve the erasure rate, the tracking characteristic is improved to apply correct tracking control.

Title: Method for preventing oxidation of metal surface
Inventor: KATAOKA KOJI
IPC: C23D5/04
Filed: 1986-10-30
Abstract: PURPOSE:To very effectively prevent the oxidation of the metal surface by bringing the aggregate of glass fibers into contact with the surface of a metal during its thermal process, melting the fibers, and forming a vitreous film on the metal surface to easily interrupt the infiltration of the oxygen and moisture in the air without contaminating the working environment. CONSTITUTION:The aggregate of glass fibers in the form of cloth, sheet, etc., is brought into contact with the surface of the metal during its thermal process such as the high-temp. slab or sheet bar in continuous casting, the hot-rolled high-temp. coils, and the slabs in a heating furnace. The glass fibers are melted by the thermal energy retained by the metal and/or the thermal energy supplied from the outside to form a continuous and uniform vitreous film without any void on the metal surface. Besides, the aggregate of glass fibers is preferably obtained by depositing or incorporating an inorg. filler such as borax and quartzite with use of an appropriate binder on or into the fibers. The film can be easily released and removed by imparting mechanical impact to the metal or bending the metal.

Title: Reproducing apparatus for magnetoresistance head
Inventor: YAMANAKA NOBORU
IPC: G11B5/02
Filed: 1992-09-02
Abstract: PURPOSE:To improve the reliability by letting a sense current gradually rise/fall. CONSTITUTION:When a reproducing operation instructing signal VB to be impressed to a time constant circuit by a resistor 16 and a capacitor 17 rises to a high level, a transistor 12 is turned conductive transiently in a time corresponding to the time constant. When the instructing signal VB falls to a low level, similarly, the transistor 12 is temporarily held in the shut state. In consequence of this, a sense current IS of an MR head 10 gradually rises from the rise time point of the signal VB, and gradually falls from the fall time point of the signal. A bias magnetic field is generated in the head 10 while the current IS is flowing, so that the operating point is biased and reproducing output voltages are generated at both ends. Accordingly, the thermal equalibrium of the head 10 is kept stably and the waveform of the output voltage is prevented from being disturbed. Since the sense current gradually falls, a bias element of the head 10 is prevented from being magnetized. When the rise and fall are arranged to be gradually carried out, the thermal fatigue of the head 10 is reduced and the reliability is improved.

Title: Method for cast molding of ceramic product
Inventor: HAMANAKA TOSHIYUKI
IPC: B28B1/26
Filed: 1987-10-13
Abstract: PURPOSE:To produce a hollow ceramic product having a complicated shape with an accurate wall thickness, by feeding a given amount of slurry into a water-absorptive mold, measuring the height of a liquid level near the slurry feed port, and draining the slurry in the mold then the measured value of the height reaches a preset value. CONSTITUTION:A given amount of slurry 3 is fed into a mold 1 and the height of a liquid level is measured with a liquid gauge 2. While suspending the feed of slurry 3, the moisture of slurry 3 in contact with the inner surface of a water-absorptive mold 1 is absorbed by the mold 1 and at the same time a thick wall of the slurry is progressively formed on said inner surface. When the liquid level of the slurry 3 near the slurry feed port descends and its height has reached a preset value, the mold 1 is turned upside down to drain the slurry 3. In this way the wall thickness can be accurately controlled by monitoring the height of the liquid level.
