    摘要： Surfaces of the structural components of a nuclear power plant exposed to reactor water are wetted with an electroless plating solution containing an electrical insulating substance. The electrical insulating substance has a high resistivity about 105 (100000) times those of the structural components of the nuclear power plant or above. A metal film containing the electrical insulating substance is formed on the surfaces of the structural components exposed to the reactor water by wetting the surfaces of the structural components with the electroless plating solution. Thus, the electrochemical corrosion potential of the structural components is reduced regardless of whether hydrogen is injected into the reactor water.

    摘要： A magnetic disk unit includes slider suspension assemblies, each of the assemblies having a slider with at least one magnetic head element and a suspension with one end portion and one surface, the slider being mounted on the one surface of the suspension at the one end portion, magnetic disks, each of the disks having at least one surface which opposes to the slider of the assembly, head IC chips electrically connected to the magnetic head elements, and a control circuit electrically connected with the head IC chips. The control circuit controls operations of each of the magnetic head elements so that the write current is applied to the magnetic head element for a first predetermined period of time and then the application of the write current to the magnetic head element is stopped for a second predetermined period of time which is equal to or longer than the first predetermined period.

    摘要： A method of testing a magnetic head with a spin-valve MR element which includes at least a pinned layer, a free layer and a non-magnetic layer for magnetically separating the pinned layer and the free layer. The method includes a step of measuring an output voltage of the spin-valve MR element under application of an external alternating magnetic field to the magnetic head in a direction parallel to a magnetization direction of the pinned layer, a step of obtaining a .rho.-H loop characteristics of the spin-valve MR element from the measured output voltage, and a step of judging pinned direction of the spin-valve MR element in accordance with a polarity of an inclination of the obtained .rho.-H loop characteristics.
