Filed: 1984-12-28
Abstract: PURPOSE:To improve the talking quality by applying clamping to a transmission system circuit so that a voltage level of a line is kept to a level higher by a predetermined value that a voltage level of a power supply circuit in response to an output of a detection circuit thereby preventing generation of noise side tone. CONSTITUTION:A value R2/R1 is selected to a value at which a transistor (TR)21 is turned on before a transmission signal voltage level VL' reaches a level VD higher than the voltage level Vcc by a predetermined value, where R2, R1 are resistance values of resistors 22, 23 of a detection circuit 20. When the transmission signal level VL' transmitted to lines L1, L2 via amplifiers 9, 10 and a TR11 from a transmitter 8 is going to change to a value lower than the level VD, the voltage at a connecting point D of the detection circuit 20 drops to a voltage turning on a TR21. As a result, the TR21 is turned on to clamp so that the transmission signal voltage level VL' of the lines L1, L2 is kept to a level higher than the voltage level VD.

Title: Cyan pigment for thermal sublimation transfer recording
Inventor: ITO NAOTO
IPC: B41M5/388
Filed: 1985-12-11
Abstract: PURPOSE:To obtain cyan pigment having excellent light fastness, high maintenance stability and satisfactory sublimation transfer by using an anthraquinone pigment for specific thermal sublimation transfer recording. CONSTITUTION:Maintenance stability, i.e. transfer of records to another recording paper is prevented by the effect of two, i.e. the first and second amino groups of anthraquinone, and subsequently, light fastness and rigidness are improved. When R of a formula (I) is represented by the cycloalkyl group, the transfer energy is low and therefore, retransfer of records seldom occurs. The synthesis of a pigment shown by the formula (I) is obtained by esterizing and then performing the reduction of 1-amino-4-nitroanthraquinone-2-carboxylic acid. To manufacture thermal transfer recording ink, pigments are mixed with any appropriate resin solvent, water, etc. In addition, as a thermal transfer technique, the ink thus obtained is applied on a base to prepare a transfer sheet, which is in turn, overlapped with a material to be recorded. After this, the sheet is heated by a thermal recording head and pressed from the reverse side, so that the pigment on the sheet is transferred to the material to be recorded.
