    摘要: The spacing between a magnetic disk surface and a magnetic head tends to greatly decrease with an increasing request for higher density records. Measuring and controlling the small spacing is important for stabilized recording or reading. A substrate is attached to a side of a support which supports the magnetic head. Light is irradiated onto a surface of the substrate and totally reflected thereby. The small spacing is measured by measuring the quantity of the totally reflected light. An actuator is controlled such that the measured small spacing is maintained at a target value to thereby realize constant small-spacing control.

    摘要: A method and system are disclosed for measuring physical quantities of a rotating body at many points thereof in a contact-free manner. The present measurement comprises electromagnetically applying control signals to the rotating body outside the body and taking out such physical quantities as mechanical strains, temperatures, etc. at many points of a rotating body with high accuracy, in a desired manner irrespective of the revolution of the body. Detecting circuits for detecting physical quantities such as mechanical strains or temperatures of a rotating body are additively and detachably provided at many measuring points of the body. The rotating body is also provided with electronic switches which can be arbitrarily changed over by control signals transmitted electromagnetically from the stationary side. The output signals from the detecting circuits are switched over by the electronic switches and transmitted electromagnetically to the stationary side.

    摘要: A lamp house is located face to face with a substrate which is transferred by a conveyer means. A dielectric barrier discharge lamp is provided in the lamp house to irradiate the substrate with ultraviolet light, while a moistened inert gas, consisting of an inert gas and water vapor, is supplied to a space between the substrate and the dielectric barrier discharge lamp from a moistened inert gas generating means. Under irradiation of ultraviolet light from the dielectric barrier discharge lamp, water vapor in the moistened inert gas is split into a reducing active member [H·] and an oxidative active member [·OH].

    摘要: While being transferred in substantially horizontal state along a predetermined path of transfer by a conveyer means, a substrate plate is dried by a jet of compressed air which is spurted out from a slit-like mouth of an air knife nozzle crosswise of the entire width of the substrate plate and at a predetermined angle of incidence with respect to a drying surface of the substrate plate to scrape off a liquid. The angle of incidence of jet air is made shallower as soon as the substrate on the conveyer means comes to a point of entry to an air blasting zone and is made deeper at latest when the substrate plate comes to a position immediately before a point of disengagement from the air blasting zone.

    摘要: Method and apparatus for a disk texturing operation in which laser pulses are successively bombarded against a delimited surface area on the face of a rotating disk, from an optical laser pulse irradiating means which is put in movement in a radial direction relative to the disk to provide a textured zone of a predetermined width on the disk. A pulsed laser beam from a laser light source is adjusted to an optimum power level for an aimed bump diameter. The laser beam is then transformed into an annular beam of a collimated light flux having specified inner and outer diameters, and the resulting laser pulses are successively bombarded on the texturing zone through an objective optical system condensing said laser pulses into a specified spot diameter thereby to form minute bumps of predetermined shape and diameter uniformly on the surface of the disk.
