摘要:
An apparatus for transferring an ink pattern image from a thermal transfer medium having an ink layer onto an image receiving medium. The thermal transfer medium is pressed against the image receiving medium and is conveyed together with the image receiving medium to a printing head and to a separating roler, in that order. A heater is provided to heat the thermal transfer medium so that it is at a given temperature when it is separated from the image receiving medium.

Y image, M image, C image and a mixed-dye image wherein Y, M and C are mixed are prepared by an image forming apparatus, analytical density for each of Y, M and C components in their complementary color wavelength regions is measured by a densitometer for each of Y image, M image and C image, then Y image, M image, C image and a mixed-dye image are read by the aforesaid image reading apparatus and spectral densities for in B, G and R wavelength regions are obtained. A conversion function for obtaining analytical density from spectral density is obtained from the spectral densities obtained by the image reading apparatus and the analytical density obtained through measurement by a densitometer.

A heat-transfer recording medium is disclosed, which produces no lowering in transfer density even when the medium is used under such higher-temperature conditions as in a facsimile equipment and is capable of providing an easily readable transferred image having a low surface gloss, as well as having an excellent keep-secrecy and producing few voids. The recording medium comprises a support; a heat-transfer layer, provided on the support, comprising a thermo-fusible substance and a colorant; and a non-transfer layer which is interposed between the support and the transfer layer and comprises a colorant, a thermoplastic polymer selected from the following Group A and a thermoplastic polymer selected from the following Group B:Group A: an .alpha.-olefin polymer, an .alpha.-olefin-maleic anhydride copolymer, an .alpha.-olefin-alkyl acrylate and methacrylate copolymer, an .alpha.-olefin-vinyl acetate copolymer, an .alpha.-olefin-acrylic or methacrylic acid copolymer, a vinyl acetate polymer, an alkyl acrylate or methacrylate polymer, a acrylic or methacrylic acid polymer and a styrene-containing polymer;Group B: A polyester resin, a polyurethane resin, a polyvinyl chloride resin and an epoxy resin.
摘要:
In a piston position detector for a fluid pressure cylinder operating by fluid pressure such as air pressure or oil pressure, a permanent magnet is mounted on a piston sliding in a non-magnetic cylinder, and a magnetic detection element to respond to the magnetic field formed by the permenent magnet and to generate detection signals is mounted to any position of the cylinder. A magnetic induction piece in sheet form is interposed between the cylinder and the magnetic detection element, so that when the permanent magnet faces the front of the magnetic detection element, the magnetic induction piece is magnetically saturated by performing bypass induction of only a part of the magnetic flux of the permanent magnet to act on the magnetic detection element and most of the magnetic flux acts on the magnetic detection element. As the permanent magnet is shifted from the front of the magnetic detection element, the ratio of the magnetic flux subjected to the bypass induction through the magnetic induction piece is increased and the magnetic flux density acting on the magnetic detection element is rapidly decreased, thereby the piston position can be detected with precise accuracy.
