    摘要: A magnetic recording medium is provided in which recording elements and concave portions have a clear difference in terms of magnetism at the boundaries therebetween, and which has favorable production efficiency. The magnetic recording medium includes a substrate; a recording layer formed in a predetermined concavo-convex pattern over the substrate, convex portions of the concavo-convex pattern serving as recording elements; and a filler portion filling a concave portion between the recording elements. A center part of a bottom surface of the concave portion protrudes from edge parts of the bottom surface of the concave portion in a direction away from the substrate.

    摘要: A method for manufacturing a magnetic recording medium is provided which can sufficiently reduce variations in surface roughness even in the simultaneous presence of a region of a relatively wide concave and convex portion and a region of a relatively narrow concave and convex portion in the recording layer. The method includes the steps of etching a recording layer based on a (first) mask layer to process it in a concavo-convex pattern, and depositing a filler over the recording layer and the mask layer to fill a concave portion with the filler. In between those steps, provided is the step of removing part of the first mask layer over a recording element (a convex portion of the recording layer) by dry etching in which an etching rate for the mask layer is higher than that for the recording layer so that the mask layer remains over the recording element.

    摘要: A device for detecting the impedance of the skin of a human body as a change of electric current comprises a time limit circuit which permits actuation of the device only one time according to a signal detected. A searching bar is coupled to the time limit circuit and has a curved or bent portion near which a luminous element is disposed. This searching bar may have adjustable sensitivity.

    摘要: A medical cell holder for use in a device which detects the impedance of a human body to actuate an electronic circuit. The holder comprises an inner assembly containing an electronic circuit; and a metallic ornamental casing having a switch mechanism at one end thereof. A cell (i.e. a battery) and the assembly are contained in said casing with the cell and the electronic circuit connected in series through the switch mechanism. The casing constitutes one electrode, which is portable in hand and which provides electrical contact with a human body.
