  • Publication number: 20050068398
    Abstract: An apparatus and method for recording an image using a transfer-type recording mechanism are such that a layer of an intermediate transfer element is removably formed on a surface of an intermediate transfer medium. The intermediate transfer element includes an ultraviolet stabilizer and a powder mixture. The intermediate transfer layer is capable of being dissolved and swelled by applying an ink liquid on the intermediate transfer medium and enables a viscosity of the ink liquid residing thereon to be increased. An image is produced on the intermediate transfer medium by supplying the ink liquid thereon. The image is then transferred to the recording medium, so that a high quality image is produced without any blurring, mixing or penetration of the ink liquid.

    Abstract: A threading unit for threading a thread through holes of a sheet-like flat member, including an upper block (2) and a lower block (3) mating with each other and each having formed therein a discontinuous vessel having apertures open on the respective mating surfaces. The upper and lower blocks, when joined together, have their discontinuous vessels connected to each other to complete a continuous vessel through which a thread is threaded. The upper and lower blocks are each split into a first upper piece (2A) and a second upper piece (2B) and a first lower piece (3A) and a second lower piece (3B), respectively, along the parting face. Each split has on its parting face a lengthwise cut half of the discontinuous vessel. The sheet-like flat member is sandwiched between the mating faces of the upper and lower blocks (2) and (3) with its holes coinciding with the apertures of the upper and lower blocks.

  • Patent number: 6591584
    Abstract: A method for producing a package of a fluidized substance is disclosed. The method includes a supplying step in which a prescribed amount of a fluidized substance (103) is supplied onto a first sheet (a first sheet 101′ of continuous length) by use of a metering-applicator (2) for the fluidized substance comprising a metering through-hole (21) having an outer opening and an inner opening. The supplying step comprises positioning the first sheet so as to be brought into contact with the outer opening of the metering through-hole (21), and then supplying the fluidized substance (103) from the inner opening of the metering through-hole (21) via the metering through-hole (21) onto the first sheet while the first sheet is conveyed.

  • Patent number: 6439713
    Abstract: A powder composition containing a powder of a modified polymer having a recurring unit containing at least one carboxyl group, the carboxyl groups of part of the recurring units being in the form of a salt with an aliphatic amine having at least 6 carbon atoms, and a powder of a surfactant. The powder composition is used for forming an image on a printing medium, in which method the composition is applied over a surface of a transfer medium to form a layer of the powder. An image of a liquid ink capable of dissolving or swelling the powder is then formed on the layer so that the viscosity of the liquid ink increases when contacted with the powder. The image on the transfer medium is contacted with the printing medium so that the image is transferred to the printing medium.

  • Publication number: 20020003815
    Abstract: A data transmission device transmits a data broadcast using a narrow unused broadcasting band in a digital broadcast, and to record the data broadcast, which has been received, on a receiving side so that the receiving side can play back the data broadcast after a data stream is totally recorded. The transmission device generates a first data stream, which is recorded on a recording medium on a receiving side, and a second data stream including audio and video data, which is transmitted as a broadcasting program. The transmission device multiplexes the first and the second data streams and then transmits the multiplexed data stream. The transmission of the multiplexed data stream is controlled so that a transmission rate for the multiplexed data stream does not exceed the maximum transmission rate, and so that a transmission rate for the first data stream becomes lower than that for the second data stream.
