Abstract: A multiplexer 13 selects the input terminal B side for a display period while it selects the input terminal A side for a coordinate detection period. A lower common drive circuit 2L, based on shift data transmitted from the multiplexer 13, operates in parallel with an upper common drive circuit 2U during the display period while it operates in series with the upper common drive circuit 2U during the coordinate detection period. An upper segment drive circuit 3U and a lower segment drive circuit 3L simultaneously operate to drive upper segment electrodes XU and lower segment electrodes XL simultaneously in the same direction. Thus, during the display period there is displayed an image simultaneously onto the upper half 1wU and the lower half 1wL of a display panel 1w, thereby improving the duty ratio of display.

Abstract: The present invention provides a process control stabilizing system including a cleaning device for the corona wires which allows the process control to be carried out optimally based on exact information which is obtained by certain sensors while a discharge from the main charger unit is kept uniform. The system is constructed so that an electrode cleaner is activated before the detection of the surface potential and/or the detection of the optical density, and in addition, the cleaning operation will be operated until the detection result falls within a predetermined range. Alternatively, the system causes detection of the surface potential and/or detection of the optical both before and after a cleaning operation by the electrode cleaner. The cleaning operation will be repeated until the difference between the first and second detections falls within a predetermined range.

Abstract: A magnetic reproduction apparatus which uses a magnetic recording medium on which frequency-modulated signals produced by frequency-modulating a carrier with video signals are recorded, and demodulates reproduced signals from the magnetic recording medium into the video signals. The apparatus includes a frequency convertor for causing the reproduced signals to shift to a higher frequency region and a pulse-count-type FM demodulator for demodulating the reproduced signals which have shifted to the higher frequency region into the video signals. This arrangement restrains the mixing of the reproduced signals in the video signals. Therefore the video signals are reproduced with lessened waveform distortion, achieving a high-quality image.

Abstract: A magnetic recording-reproduction apparatus records and reproduces a wide-band video signal without a color burst signal. For this purpose, a two-step phase resetting operation is conducted on the FM carrier at the front porch and the horizontal sync pulse of the video signal so as to permit those phases to coincide with reference phases. A synchronizing panel clock generator generates the first reference signal with the first FM frequency corresponding to a peak level of the horizontal sync pulse and the second reference signal with the second FM frequency corresponding to a front porch level. In this case, the reference signals are phase-synchronous with each other at the leading edge of the horizontal sync pulse, and each of the FM frequencies is set to be an integer multiple of the horizontal scanning frequency.

Abstract: A transport path is branched into a main pass and a bypass. A deflector is provided at a branch point, for switching the path either to the bypass or to the main pass.

As a result, the problem of the device being made larger or reducing the quality of the sheets can be prevented, and a faster process after copying can be achieved.

Abstract: A system for detection of errors in received data can also provide for the correction of errors so detected. The system has a FSK decoder section (10), an error detection module (24) and an error correction module (12). The received data, RXSIGIN, is bandlimited by bandpass filters (14), with the resultant waveforms provided to the error detection module (24) on lines (29). The FSK decoder section (10) also decode the digital data RXDATA within RXSIGIN, and provides RXDATA to both the error correction detection module (24) on line (21) and the error correction module (12) on line (33). Error detection takes place on a bit-by-bit basis by comparison of the resultant waveforms being compared against an ideal representation thereof, a quality factor is ascribed to each bit on the basis of the comparison, and a determination of which bits are suspected to be in error is made by comparison of the quality factor against a threshold value (30).

Abstract: An image-quality stabilizer for an electrophotographic apparatus forms a toner patch on a photoreceptor drum, detects the amount of toner attracted to the photoreceptor drum by an optical sensor, and controls each processing device so that the detected value is equal to a reference value which has been detected and stored when the number of image forming operations performed is low. After the control, the toner patch is transferred to a transfer sheet, and the amount of toner remaining on the photoreceptor drum is detected. The reference value is adjusted based on the detected value so as to compensate for a lowering of transfer efficiency. Or the lowering of transfer efficiency is compensated by controlling variables such as transfer output so that the detected value is equal to a reference residual value which has been detected and stored when the number of image forming operations performed is low. This arrangement restrains a lowering of image density due to a change in the transfer efficiency.

Abstract: A magneto-optical recording apparatus which records information through the processes of: first irradiating a light beam onto a magneto-optical recording medium having a recording film; and next applying an external magnetic field that is inverted in response to a recording signal onto the recording film while continuing the first process. In the above arrangement, the intensity of the light beam is dropped upon inversion of the external magnetic field so that information is not recorded. The intensity of the light beam is raised during non-inversion of the external magnetic field so that information is recorded. Further the magneto-optical recording apparatus is provided with a light intensity control device for varying the intensity of the light beam dependent of the lengths of recording bits so that the high-temperature area of the recording film is not widened.
