IPC: H04B1/16
Filed: 1979-10-01
Abstract: PURPOSE:To prevent the lowering of isolation degree for the left and right signals of the demodulation signal, by reducing the duty factor of the regenerated subcarrier and thus sampling the composite signal. CONSTITUTION:The stereo pilot signal to be supplied to the terminal 1 receives the phase comparison 2 with the signal of 19kHz sent from the FF15, and the output based on the phase difference controls the VCO10. In this case, the output of the VCO is divided 11, and each division output is turned into the signals (b) and (c) of 76kHz each having a phase difference of 90 deg. by the FF12 AND 13. The signal (b) is divided 14 furthermore to be turned into the signals (d) and (e) of 36kHz each having an opposite phase to each other. The signal (e) is divided through the FF15 to be led out in the form of the signal of 19kHz. Then the logic products 17 and 18 are obtained between the signals (c) and (d) as well as between (c) and (e) each. And thus the signal having a phase difference of 180 deg. at each output and with a duty factor of 25% each is produced to obtain the reproduced subcarrier.

Title: Controlling method for printing of printer
Inventor: HANEDA SHINJI
IPC: B41J2/485
Filed: 1990-05-18
Abstract: PURPOSE:To raise an efficiency of printing a lateral extension character by an arbitrary magnification by recognizing a magnification (n), selecting a constant (m) of a minimum integer number by converting it to the integer number, increasing the interval of dots and the number of dots to be printed laterally by (n x m) times, setting the feeding speed of a printing carrier to l/m, and incorporating steps of printing (nXm) pieces of dots at the same responding speed as a normal character. CONSTITUTION:A controller 5 first identifies by an identifier 50 a desired character size 'n' at a printing sentence in one row, and selects a constant 'm' to be converted to integer number by multiplication by a selector 51. In this case, an enlarged printing control is adapted by selecting a minimized integer number. Further, it is enlarged by 'nXm' times at the time of converting dots of the printing data by a converter 52. The data are printed by a printer 4 at a responding speed corresponding to the normal character of a printing head l at a speed 53 of 'l/m' at the time of printing the normal character. Thus, the character enlarged by 'n' times as large as the lateral size is printed. It is not necessary to particularly control a dot pitch, but printing density can be made uniform by easy control. Even if the normal printing character and the enlarged printing character are mixed, it can be printed by one feeding in one direction.

Abstract: PURPOSE:To prevent the occurrence of crosstalk between left and right eye information by providing the first and second shutters which face each other with a voltage controlled polarizing element and consist of a pair of polarizing filters different in angle of polarization and are different in angle of polarization of output light and opening and closing them alternately at a prescribed period. CONSTITUTION:When voltage signals S1 and S2 impressed to PLZT (lead lanthanum zirconate titanate) 6 and 7 are 'O', the angle of polarization is not changed though the light beams pass PLZT 6 and 7, and the light beams cannot pass pairs of polarizing filters 8 and 9 and polarizing filters 10 and 11 which face each other respectively with PLZT 6 and 7 between them and are different in angle of polarization by 90 deg., and shutters 12 and 13 are approximately completely closed. When signals S1 and S2 are V, double refraction occurs in PLZT 6 and 7; and if the voltage level V of voltage signals S1 and S2 is a half-wave length voltage, the light is circularly polarized at 90 deg. when passing PLZT 6 and 7 and passes analyzers 9 and 10. Thus, the voltage level of voltage signals S1 and S2 are set to 'O' and V alternately in every one-field period to open and close shutters alternately.
