IPC: G11B11/105
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To suppress heat generation in pulsatively driving the magnetic head coil of a magneto-optical recording device. SOLUTION: A signal TRDET which has an H level when the magnetization inversion of data is present and an L level when it is not present is generated by data inversion detecting means 41 to 44. Moreover, means 45 to 47 which reduce exciting energy using this signal TRDET generate a strobe signal STRB which shortens an H-level period when the magnetization inversion of the data is present and makes the period a normal H-level period when it is not present. Then, the magnetic head coil is energized only in a period when the strobe signal STRB is at an H level to generate magnetic fields to be impressed on a magneto-optical recording medium in pulsative form.

Title: Protective structure for water-barriering sheet
Inventor: KUROIWA MASAO
IPC: B09B1/00
Filed: 1993-10-05
Abstract: PURPOSE:To easily and certainly form a protection layer in a specified thickness over water-barriering sheets laid over a steep slope or a rugged surface. CONSTITUTION:A protection layer 11' for water-barriering sheets 10 laid over a steep slope is formed of spray foaming urethane. In other words, as an undiluted solution of spray foaming urethane is sprayed with a mixing gun 13 directly to the surface of the water-barriering sheets 10 after dust or the like is removed from the surface of the water-barriering sheets 10, the undiluted solution is foamed instantaneously and hardened, forming a foam body with minute bubbles, and thereby the protection layer 11' can be formed easily. As the spray foaming urethane is highly adhesive to the water-barriering sheets 10, the water- barriering sheets do not slip down although they are laid over the steep slope, and the water-barriering sheets 10 can be protected.

Title: Surface treatment of amorphous alloy material
Inventor: OKAZAKI YASUO
IPC: H01F41/02
Filed: 1986-10-20
Abstract: PURPOSE:To improve the iron loss, interlayer resistance, and corrosion resistance of the title material by using a multi-stage electrolytic cell, and coating a material having a magnetic deterioration inhibiting action on the surface of the material at the time of depositing an oxide on the surface of the material by anodization. CONSTITUTION:A thin amorphous alloy band A travels between the cathodes 4 of the electrolytic cells 1a-1c which are arranged in multiple stages and provided with conductor rolls 2 and sink rolls 3. The distance L between the respective rolls 21 and 22 in the lengthwise direction of the thin band A is controlled so that the voltage drop due to the length of the electrode is not remarkably increased. By this method, the thin band A is continuously anodized at a high rate without deteriorating the electrolysis efficiency, and an oxide-based insulating coated film can be formed on the surface. The coating material having a magnetic deterioration inhibiting action is then coated on the surface, and the material can be uniformly coated at this time and coated over the whole surface of the thin band A in cooperation with the oxide. Accordingly, the electric resistance of the surface of the interlayer resistance is increased, and an eddy current is also reduced. Since the thin band A having high activity is not exposed directly to the atmosphere, the corrosion resistance is also improved.
