Title: Recording apparatus
Inventor: SUGIURA KENICHIRO
IPC: B41J2/485
Filed: 1988-12-05
Abstract: PURPOSE:To reduce the load of a CPU by employing constitution provided with an image data processing means for extending the image data compressed by a predetermined image data compression means to the original image data. CONSTITUTION:The control system of a printer is constituted of a CPU 11, an ROM 12 and an RAM 13 and a printing mechanism part 15 performing recording is connected to the CPU 11 through an input/output port. The control circuit of the printer is connected to the control circuit of a personal computer main body through a circuit 14. At the time of facsimile transmission, the image data of a transmitted manuscript is read by an image scanner under the control of the CPU 1 of the personal computer main body and encoded by the CPU 1 to be compressed and subsequently modulated to an image signal according to a predetermined modulation system in a modem 7 while the image signal is sent to a telephone circuit 9. At the time of facsimile reception, an image signal is received from the telephone circuit 9 through an NCU 8 and demodulated according to the demodulation system corresponding to the modulation system by the modem 7. By this method, since it is unnecessary to perform the extension of image data on the side of the computer main body, the processing load of the CPU can be reduced.

Title: Display controller
Inventor: SATO MITSUYOSHI
IPC: G09G3/18
Filed: 1992-10-19
Abstract: PURPOSE:To maintain high-quality images and to prevent the misunderstanding of the disturbance in the images under synchronizing processing as a fault by providing a display suppression processing section which forcibly stops the display of arithmetic processing information in a display section while a display suppression signal is outputted. CONSTITUTION:A mode changeover detection section 13 extracts abnormal frequency components by using a frequency filter, etc., and detects the start of mode changeover processing. The display suppression processing section 15 operates to prevent the recognition of the disturbance in the image in the display section 12 by turning off the back light of the display section 12 during the specified display suppression time which is previously determined. Such disturbance in the image ends in fractions of a second and, therefore, the display suppression time is merely necessitated to be preset at about, for example, one second. The time delay after the detection of the disturbance in the synchronizing signal before the turning off the back light by the display suppression processing section 1 is several milliseconds and, therefore, the disturbance in the images during this time is substantially negligible.

Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To surely remove differential error component independently of the rotating speed of a motor by controlling the timing of sampling on a gate signal generated through mutual comparison among a sine wave signal outputted from an encoder, an inversion sine wave signal and a signal obtained by multiplying the sine wave signal by a fixed coefficient.
