  • Patent number: 5805312
    Abstract: An image copying system is disclosed which has a thermal head energized at a strobe current supply time rate corresponding to a current head temperature according to a preset strobe current supply time rate control characteristics. In copying operation at a standard speed, a read sensor 211 reads an image by performing N main scans in one sub scan. A signal processor 221 validates the image signal thus read once every N scans according to a selection signal from a mode control circuit 401. A record circuit 311 having a thermal head performs one main scan every sub scan. During a copying operation at a speed N times the standard speed, the sub scan speed is made N times and the read sensor 211 reads the image by performing one main scan every sub scan and the signal processor 221 makes the read image signal always valid by the selection signal. The record device 311 performs one main scan every sub scan. A single A/D converter is used for A/D converting head temperature as well as other output signal.

  • Patent number: 5288610
    Abstract: A detecting reagent for an antiplatelet antibody, comprises a carrier particle, and a platelet antigen component immobilized on a surface of the carrier particle. The reagent particles do not agglutinate with each other, contrary to the platelets subjected to natural agglutination, probably because the platelet membrane antigen component immobilized on the carrier particle is solubilized in advance.

  • Patent number: 5259680
    Abstract: A thermal transfer printer which can use both an ink sheet provided with a positioning mark to indicate the top position of a set of three color ink patches necessary for producing one image, and an ink sheet provided with no such positioning mark, without the need of switching an operation mode. The thermal transfer printer has an optical sensor which can equally detect a color change between 3rd and 1st color patches on the ink sheet provided with no positioning mark and a color change between a positioning mark and a 1st color patch on the ink sheet provided with the positioning mark. There is also disclosed an ink sheet cassette for use in the thermal transfer printer, the ink sheet cassette accommodating the ink sheet in which a positioning mark is coated with the same color(s) of ink as those for printing and information about the color sequence of the ink coated patches for printing is also recorded in the coated pattern of the positioning mark.

  • Patent number: 5251074
    Abstract: During the playback operation for freezing and storing a specific frame of a picture in a memory and thereafter printing the frame, the recording medium is turned reversely for a prescribed amount according to an instruction from a printer in response to the entry of the freeze command in order to accurately search the frame at the entry of the freeze, and thereafter the recording medium is played back in normal mode. The amounts of reverse turn and the successive forward turn in normal playback are counted and compared, and when the difference has become a prescribed value, a freeze signal is produced and the frame of the picture selected by the freeze command is stored in the memory and printed when required. This control method for use in a video print system is designed so that the recording medium is turned reversely for a prescribed amount according to an instruction from the printer and then stopped until the next command is entered.
