Title: Image drawing method and device therefor
Inventor: KUMAMOTO GEN
IPC: G06T5/20
Filed: 1993-12-28
Abstract: PURPOSE:To draw fast an image which shows the depth of field. CONSTITUTION:In reference to an image including the objects 5, 6 and 7, 8 small sampling rate is set for a pixel area 10 of a small sampling degree so that the accurate luminance value is calculated. Meanwhile, a large sampling rate is set for a pixel area 12 of a large defocusing degree so that the luminance different value of a sampling pixel is calculated. Thus, the different sampling rates are set according to the defocusing degrees, and only the luminance of the sampled pixel is calculated by the decentralized rate racing method. Then, luminance value of sampled pixels ere calculated by the linear interpolation applied among these pixels. Thus, it is possible to extremely shorten the time needed for calculation of the luminance of a defocusing area without deteriorating the substantial image quality.

Filed: 1992-11-27
Abstract: PURPOSE:To prevent wear and to reduce noises by forming a cam for vertically moving a column up and down in a disc state, and rotatably driving it at a deviated position of the disc via a clutch mechanism. CONSTITUTION:A cam 71 formed in a disc state and a drive shaft 73 are not fixed, a one-way clutch 75 is so disposed between the shaft 73 and the cam 71 as to be idle in one direction and to be slipped at a stage when a rotational speed of the cam 71 exceeds that of the shaft 73. When a position of the cam 71 at the time of rotation is represented by a position of a center of gravity G, a load direction to the position of the gravity G is reverse to the driving direction of the shaft 72 at a stage in which the gravity G is raised by a force of a motor 27, and hence a torque is transmitted to the cam 71 as it is, but from a stage in which the gravity G exceeds a top dead center to convert its movement to a downward direction, the load direction to the position of the gravity G becomes the same as the driving direction of the shaft 72, and the rotational speed of the cam 71 exceeds that of the shaft 73. At that moment, the clutch 75 is operated, the cam 71 is rotated at a high speed, and a placed column is dropped with a thud.

Title: Image-forming device and electrophotographic photoreceptor used therein
Inventor: TAKEUCHI SHIGEKI
IPC: G03G5/10
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To prevent curling of a photoreceptor having flexibility and to prevent image irregularity by setting creep width within a specified value, when applying specified stress strain to the photoreceptor. SOLUTION: In this image-forming device, where the electrophotographic photoreceptor provided with a photoreceptive layer on base substance having the flexibility is driven by using a driving roller whose diameter is 25 mm or smaller, the creep width is set within 0.01% when the stress strain of 0.5% is given to the upper roller 3, the lower roller 5 and the lateral roller 7 of the photoreceptor 1. In the image-forming device using the upper, the lower and the lateral rollers 3, 5 and 7 of the photoreceptor 1, whose diameters are 25 mm or smaller, the curl deteriorates suddenly, when the creep width exceeds 0.01% when applying the stress strain by 0.5% to the photoreceptor 1 and a phenomenon occurs in that the curl cannot be removed ever a considerably long time.  When the image is formed in such a state, the image irregularity caused by curling, especiallys, the image irregularity in the direction perpendicular to the advancing direction of the photoreceptor 1 can be caused to occur cyclically.
