    摘要： The present invention provides a heat transfer printer, a heat transfer process and a heat transfer ink sheet (1; 11), where a letter or image or both is recorded by selectively heating a heat transfer ink sheet (1, 11) having ink layer regions each containing a sublimable or vaporizable dye by heating by a thermal head controlled by a con­trolling means, thereby selectively heat transferring the sublimated or vaporized dyes on a recording sheet (17), and is characterized by heat transferring a precoating layer (13) for the dyes from the ink sheet (1,11) onto the recording sheet (17) before the heat transfer recording, and then laying the ink sheet (1,11) on the precoating layer (13) transfered on the recording sheet (17) by the thermal head, thereby sublimating or vaporizing the dyes from the respective ink layers onto the precoating layer (13) and forming the letter or image or both on the recording sheet (17).

    摘要： An optical apparatus comprises an optical device (10) having an optically functional material (6) sandwiched between a pair of substrates (3) with electrodes (5) formed on opposing surfaces. The optically functional material has such a characteristic that intensity of light issuing from the optical device changes asymmetrically in response to inversion of the polarity of an applied external field. Pulse voltages of one polarity for determining the intensity of the issuing light and pulse voltages of an opposite polarity are applied from a source (8) at a predetermined period (T) so that an average voltage is zeroed within the predetermined period. The issuing light intensity under the application of the pulse voltages of one polarity and the issuing light intensity under the application of the other pulse voltages are selected or changed by a switching unit (20).
