Filed: 1990-09-25
Abstract: PURPOSE:To reduce the chip size and cost of this circuit by providing a reload register, overflow detection circuit, 1/2-frequency divider, and reload signal generating circuit and reducing the total bit length of a counter required for obtaining a pulse width modulated(PWM) output to a half. CONSTITUTION:A reload register 16 holds the digital value (n) of input data and, when a 1st reload signal is inputted, loads the digital value (n) on a counter 17. When a 2nd reload signal is inputted, the register 16 loads the complement (n') of '1' on the counter 17. A T type flip-flop 20 alternately changes its output signal between a high and low levels whenever an overflow signal is generated and outputs the output signal as a PWM signal. Namely, two different timing is made to be recognized by using one counter. Therefore, the chip size and cost of this pulse width modulating signal output circuit can be reduced, since the number of used elements can be reduced.

Title: Video memory circuit
Inventor: TOMATSURI KOICHI
IPC: H04N5/907
Filed: 1988-10-14
Abstract: PURPOSE:To reduce a noise due to unrequired radiation, etc., and current consumption in a memory IC by stopping the supply of a clock to the memory IC not selected when the output of plural memory ICs are used selectively. CONSTITUTION:Gates 9 and 10 are inserted, and the clock from a pulse generator 8 is supplied by switching to memories 3 and 4 by a pulse in which a vertical synchronizing signal VSYNC is 1/2-frequency divided. Thereby, the output (f) of a clock pulse generator CPG 8 is distributed to the gates 9 and 10 as (g) and (h) by the output (c) of a 1/2-frequency divider 18. Since the output state of the memory IC to which no clock is supplied remains unchanged, no noise synchronized with the clock is generated, Also, the current consumption can be reduced compared with a case where the clock is supplied to two memory ICs simultaneously.

Title: Picture processor
Inventor: MITA YOSHINOBU
IPC: G06T5/00
Filed: 1984-12-07
Abstract: PURPOSE:To break the cyclic property of a dither matrix for the suppression of moire by advancing or delaying the phase of the generation pattern of the dither matrix by a prescribed amount when the density difference produced between periods before and after the dither processing exceeds the prescribed threshold value. CONSTITUTION:An input picture signal is turned into a binary picture signal 3 by a dither circuit 2. The circuit 2 performs a binary coding operation by the dither threshold value designated by an address generating part 12. The block adders 4 and 5 produce the sums 6 and 7 of picture signals of the prescribed block obtained before and after the dither processing. A difference signal 9 obtained by subtracting the sum signal 7 from the sum signal 6 is coded properly by a quantizing circuit 10. This quantized signal 11 is defined as the phase correction amount of the main scan direction address produced by the part 12. Thus the phase modulation is given to the generation of the dither threshold value of the main scan direction to the next block. Thus the cyclic property of the dither matrix is broken in the main scan direction. As a result, the moire produced by the interference between said cycle property and the cycle property secured at a melting point can be suppressed.

Abstract: PURPOSE:To uniformize the thickness of a coating film in a structure for applying a photosensitive soln. on the outer surface of a hollow drum to obtain an electrophotographic sensitive body by forming a special step at the engaging ends of the spacer and drum and forming a guide surface. CONSTITUTION:When the spacer 3 and the drum 1 are connected, a step 3A with the outer diameter smaller by the wall thickness (t) of the drum 1 is formed over a certain length at the engaging ends of the spacer 3 and drum 1. A guide surface 3B tapered from the terminal end of the step 3A toward the drum 1 side is formed. The inner surface of the drum 1 and the step 3A are closely engaged beyond the guide surface 3B, and hence the drum 3 is hardly disconnected from the spacer 3 in handling. Consequently, the drum 1 and the spacer 3 are moved coaxially with a coating head 2 at all times, and the drum is not detached from the spacer.
