    摘要: Information is printed on the surface of a substrate with a marking ink containing a mixture of an indium-tin mixed oxide and at least one compound selected from the group consisting of alumina, barium sulfate, silicon dioxide and calcium carbonate, to prepare an invisible marking-printed material; and infrared rays of 2-10 .mu.m wavelength are applied onto the invisible marking-printed material to measure the infrared absorptivities of the invisible marking area and other area of said material and identify the information signified by the invisible marking.

    摘要: An aqueous solution containing sulfuric acid and hydrogen peroxide is used for a soft etchant in a soft etching step in a smear removing process performed prior to a catalyst applying process for chemical copper plating after formation of via holes through an insulating layer of a multi-layer substrate by irradiation of laser. The concentration of sulfuric acid is 2.4 times or less than the concentration of hydrogen peroxide. Preferably, the concentration of sulfuric acid is in a range of 9 to 90 g/l, and the concentration of sulfuric acid is lower than the concentration of hydrogen peroxide. More preferably, the concentration of sulfuric acid is in a range of 9 to 18 g/l, and the concentration of hydrogen peroxide is in a range of 33 to 38.5 g/l. As a result, smear can be certainly removed without excessively etching a conductive layer in the smear removing process.

    摘要: A method for reading of information, which comprises printing information on a metal substrate or a substrate capable of transmitting infrared rays of 2-10 .mu.m wavelength, with a marking ink containing tin oxide, indium-tin mixed oxide or a mixture of tin oxide or indium-tin mixed oxide and at least one compound selected from the group consisting of alumina, barium sulfate, silicon dioxide and calcium carbonate, as necessary coating a clear coating or a coloring ink on at least the information-printed area of the substrate, and identifying the information by the use of a CCD camera sensitive to infrared rays of 2-10 .mu.m wavelength or an infrared detector. No noise is generated even when the reflectance of a light from the substrate surface is large, and the information can be identified (read) easily.

    摘要: For an enhanced coupling efficiency between a light source and an optical fiber bundle: the optical fiber bundle is made up by a dense bundle of optical fibers, with an integrated portion composed of fusion-integrated distal ends of the bundled optical fibers, and the integrated portion has, in a longitudinal sectional plane along a center axis of the optical fiber bundle, a lateral side thereof formed, in a shape of arc radially outwardly convex with respect to a straight line interconnecting an end point at a front end face side of the integrated portion and an end point at a rear end side thereof, to locate at a radially inner side with respect to an extension toward the integrated portion of a line constituting an outline of a portion else than the integrated portion of the optical fiber bundle.
