摘要:
A printing control method causes a printer to print data of even pages on one side of respective recording media, thereafter causes the printer to print data of odd pages, except for the last page if it is an odd page, on the other side of the recording medium, on one side of which the data of the even pages were printed and which were manually set in the sheet feeding device by an operator, and thereafter causing the printer to print data of the last page on a recording medium different from the recording media, on one side of which the data of even pages are printed and which were manually set in the sheet feeding device by the operator, if the last page is an odd page.
摘要:
There is disclosed a control method for printing a plurality of pages of print data on both sides of the recording medium without using a both side printing mechanism. The method comprises the steps of outputting print data of one of even and odd pages to be printed on one side of the recording medium to printing means, prompting the operator to set the recording medium having print data of one of even and odd pages printed on one side to sheet feeding means, outputting print data of another of even and odd pages to be printed on the recording medium having print data of one of even and odd pages printed on one side to the printing means, detecting a jam on the printing means, designating the pages to be printed on both sides of recording medium which is lost due to the jam, when the jam is detected during printing of print data of another of even and odd pages by the printing means, outputting print data of one of designated pages to be printed on one side of a newly supplied recording medium to the printing means, prompting the operator to set the recording medium having print data of one of the designated pages recorded on one side thereof to the sheet feeding means, and outputting print data of another of the designated pages to be printed on another side of the recording medium having print data of one of the designated pages recorded on one side to the printing means.

In order to perform printing by using a minimum of band buffer and correcting bending/inclination in a sub-scanning direction without making optical adjustments and using special hardware, 1-band image data are stored in the band buffer, images stored in the band buffer are corrected, images lying outside a band area are stored in an intermediate buffer, and images including images stored in the intermediate buffer and corrected images of a next band that lie inside the band area are output.

A television synchronous receiver is arranged to maintain a 90.degree. phase difference in the broad frequency band of a TV broadcast between a local oscillator signal and another local oscillator signal. This allows a pair of synchronous detectors to detect the in phase components and quadrature components of a received television broadcast signal. A Costas loop is utilized in the generation of the 90.degree. phase difference.

A channel selector characterized in that a plurality of receivers capable of simultaneously performing a receiving operation have a main part of a phase-locked loop frequency synthesizer connected in common thereto, the frequency synthesizer having a programmable frequency divider, a phase comparator, a reference oscillator and a reference frequency divider. The frequency synthesizer is controlled so that a local oscillation frequency corresponding to a determined frequency close to a broadcast signal of a desired receiving channel is synthesized, and one of a plurality of search tuning systems searches and tunes the broadcast signal from the local oscillation frequency.

A channel selector comprising a tuning circuit including a variable reactance element as a tuning element and a non-volatile memory for permanently memorizing coded signals of channel selecting voltages to be applied to said variable reactance element, and being arranged in such a manner that the channel identification numbers and the coded signals for selecting these channels can be correspondingly memorized preliminarily in said non-volatile memory, and in channel selection the coded signal of the channel selecting voltage corresponding to a desired channel can be read out from said non-volatile memory, converted into a voltage and applied to said variable reactance element to achieve channel selection. A selected channel does not change by the cutting of the power source and the device is purely electronic. The device is especially effective for use in a television receiver.
摘要:
A sweep output generator in which an a-c voltage of small amplitude is superimposed upon a sweep voltage applied to a variable reactance element of a local sweep voltage controlled oscillator for sweeping the local oscillator frequency and also for frequency modulation. The frequency modulated local sweep oscillator output and the output of a second voltage controlled oscillator are coupled to a mixer to obtain an intermediate frequency signal. The intermediate frequency signal is frequency demodulated through a frequency discriminator, whose output is in turn integrated to obtain a sweep output voltage of a characteristic similar to the normalized oscillation frequency versus impressed voltage characteristic of the local oscillator.
