Title: Aquatic life deposit preventing structure and pipe regeneration member
Inventor: HASHIMOTO KEISUKE
IPC: B32B27/28
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To develop an efficient stain preventing effect in water for a long time by laminating a second resin layer to control the amount of dilution of a stain preventing agent on the surface of a first resin layer in which the stain preventing agent is compounded with a copolymer resin. SOLUTION: A stain-proofing agent is compounded with a resin copolymer resin of ethylene and an organic carboxylic acid ester derivative with ethylenic unsaturated bonds according to the period needed for effective prevention of stain so as to form a first resin layer 111. Also a second resin layer 112 comprising a resin with acid amide bond in main chain is laminated on the surface of the first resin layer 111 so as to control the excessive elution of the stain- proofing agent. Then the resin has a permeability of the stain-proofing agent sufficient to show a stain-proofing ability against aquatic life deposit and can dilute the stain-proofing agent substantially at a constant rate for long period. Thus the effect of stain-proofing is stabilized.

Title: Magnetic disk device
Inventor: SUGIMOTO YUKIMASA
IPC: G11B20/10
Filed: 1985-12-12
Abstract: PURPOSE:To improve productivity and quality by providing a subtraction means which subtracts the number of tracks shifted from the number of a track on which a positioning control means positions a magnetic head and reports the effect to a host device. CONSTITUTION:When the host device 2 wants the number of the track where the magnetic head at that time is positioned, a microprocessor circuit 4 returns the value obtained by subtracting the value of a track shift designation switch 8 from the number of the track on which actually magnetic head is positioned to the host device 2 through an interface logic circuit 3. Accordingly, the host device 2 does not sense that the number of the track propagate through the interface logic circuit 3 has a deviation from the track number which the track actually seeks. Thus such adjustment can be made that defects of a magnetic disk medium never comes to a specific track which ensures no defect and is seeked according to the instruction of the host device, and therefore the manufacturing yield of a magnetic disk device can be improved.

Lead fluoride 11, generated in the above process, is dipped in nitric acid and further in dilute nitric acid and is eliminated by cleaning, using hot water and ultrasonic wave. After drying, heat treatment is performed in a hydrogen atmosphere at a specific temperature, thereby eliminating lead ions. By electroless nickel plating, an anode electrode 20 and a cathode electrode 30 are formed. Hence electrodes can be formed uniformly and densely in a wafer, wherein the electrodes make ohmic contact with a semiconductor region with good adhesion.

Abstract: PURPOSE:To aim at restraint of unstable vibration, and prevention of damage to a shaft by forming a spring located between a bearing member and the inside bottom of an oil tank with the material which is deformed due to temperature, extended more and applying stronger axial pushing force to a bearing portion in a rated rotation in comparison with the case of start/low rotational speed, at the time of a rated rotation. CONSTITUTION:A spring 25 in the state of no-contact with a ball 15 held and guided by a retainer 14 is arranged between the bottom face in an oil tank 10 and a bearing member 12. This spring 25 is formed with a shape memory alloy which memorizes its both shapes at the time of high/low temperature so that the length of a shaft 20 in an axial direction at the time of high temperature in a rated rotation becomes longer than the length in the axial direction at the time of starting/stoppage and a low rotational speed for making its property of an operation as an compression spring stronger. Accordingly, there is neither load nor restraint in the axial direction due to the spring 25 at the time of low temperature, so that the unstable vibration of the shaft in a low speed is restrained and the spring follows the floating of the shaft 20 in the case of rated rotation to be able to prevent the damage to the bearing.
