Title: Medical image processor
Inventor: SASAJIMA YOSHIO
IPC: G06F17/00
Filed: 1993-11-12
Abstract: PURPOSE:To inform an operator of that a body overlaps with the tube wall of a tubular body in such a case by simulating whether or not the body can pass through the tubular body. CONSTITUTION:The tubular body and the body to pass through the tube are extracted (101) from three-dimensional image data (100) which are read in, their stereoscopic images are put together and displayed (103), and only the passing body is moved (104) on the image while optionally changed in direction. When the sum of pixel values of the passing body and tubular body exceeds a specific value, it is judged that they overlap with each other and the operator is informed of that in this cue by a method for changing the color of the overlap part, etc.

Title: Dispersing device
Inventor: IIZUKA HIDETOSHI
IPC: F42B12/36
Filed: 1989-10-30
Abstract: PURPOSE:To permit the dispersion of dispersing matters immediately after injecting out of an injection tube by a method wherein a core, which delivers a force upon injection to the cap of the injection tube, is provided and the dispersing matters are received in the injection tube. CONSTITUTION:A core 13, which delivers a force upon injection which is generated at the back part of an injection tube 3 to a cap 5 at the fore end of the injection tube, is provided while dispersing matters 1 are received by the core 13 into the injection tube 3. In an actual operation, the injection tube 3 pushes out an injection plate 6 by the explosive force of a cartridge actuator 4. This push-out force is received by the core 13 and the cap 5 is injected out of the injection tube 3 and, at the same moment, the core 13 is injected to the outside of the subject device together with the dispersing matters 1. The dispersing matters 1 are not received into a vessel or the like and, therefore, they are dispersed to the outside of the injection tube as they are. According to this method the dispersing matters 1 may be dispersed immediately after injecting them out of the injection tube 3 while the structure of the subject device can be simplified.

Abstract: PURPOSE:To permit the application of the proper engine brake corresponding to the car speed by installing a detecting means for detecting the actual accelerator stepping-on position, means for detecting car speed, and a control means for controlling the speed ratio of a continuously variable transmission. CONSTITUTION:A control means receives the actual accelerator stepping-on position and car speed from both detecting means, and sets a stepping standard point by carrying out position shift to the stepping-on side as the car speed increases more, and when the actual accelerator stepping-on position is shallower than the stepping-on standard point, the speed ratio of a continuously variable transmission is controlled so that engine brake changes according to the magnitude of the shift between both. Accordingly, when a driver steps on an accelerator, exceeding the stepping-on standard point, the ordinary acceleration operation is carried out, while if the stepping-on of the accelerator is made shallow in comparison with the stepping-on standard point, engine brake corresponding to the shift quantity from the stepping-on standard point to the stepping. on position at present is applied through the control means.

Title: Device and method for processing image
Inventor: ASANO MASANARI
IPC: H04N9/804
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To store image data in a small capacity frame memory by thinning all chroma data on one line in inputted image data for one frame and remaining chroma data on the other line. SOLUTION: Concerning image data D1 to be inputted for one frame, all the lines have luminance data and chroma data. When writing image data D2 in a DRAM 1, all the chroma data on one of two adjacent lines are thinned and the chroma data on the other line remain. The chroma data on the other line are written in the different row addresses of the DRAM 1 while being divided into 1st and 2nd chroma data. On the other hand, the luminance data are written in row addresses different for each line inside the DRAM 1. When the chroma data are thinned, the amount of data can be reduced without lowering picture quality so much in comparison with the case of thinning the luminance data.

Filed: 1986-11-29
Abstract: PURPOSE:To secure switching operation for imprinting modes by controlling a film feeder not to operate until both a shutter and a data imprinting device finish operation. CONSTITUTION:Images of documents are imprinted on a film F through the operation of the shutter 168 associatively with film feeding rollers 47 and 48. The photographing operation of this shutter 168 is controlled by an automatic exposing device and an imprinting exposure time is adjusted according to the light and shade state of a document image to be imprinted on the film F. Consequently, images of many documents are imprinted automatically on the film while proper exposure times corresponding to the light and shade states of the respective documents are set. The rollers 47 and 48 are controlled by a microcomputer and the rollers 47 and 48 of the film feeder do not operate until both the shutter 168 and data imprinting devices 201a, 201b, and 201c finish operation, thereby precluding a failure in imprinting due to the feeding of the film during shutter operation or data imprinting operation.
