Title: Dithering device
Inventor: MIURA HIDEKI
IPC: G06T5/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To improve a dithering process speed by storing a circular array for circulating an index for designating each threshold value in a dither pattern, extracting a threshold value in the dither pattern corresponding to a picture element in image data by referring to the circular array, and operating a binarization processing. SOLUTION: The pixel value under consideration of a coordinate indicated by (Ix, Iy) in image data 11 is compared with a corresponding threshold value in a dither pattern 12 indicated by a coordinate (Px, Py) calculated from an index. When the pixel value of the image data is larger, a picture element is punched, and otherwise, 1 is added to 1x for moving a picture element for dithering to a right direction by one picture element, and Px is updated according to the update of Ix. This processing is operated by referring to a circular array 20 stored in a circular array storing part 5, and Px is updated to 20B corresponding to an index 20A being the value of the present Px. Therefore, the next index can be quickly calculated without operating any remainder arithmetic operation or comparison judging processing.

Title: Heat transfer pipe
Inventor: ISHIMATSU HIROYUKI
IPC: F28F1/40
Filed: 1986-10-21
Abstract: PURPOSE:To control the heat transfer rate by a simple manner, and to increase the controllable range of heat transfer rate, by operating to stretch a soft tube which is inserted in a heat transfer pipe, or by simply moving the tube. CONSTITUTION:A soft tube 2, made of material such as rubber or polymer, connected to a line such as a wire 3, is inserted in a heat transfer pipe 1. When a large heat transfer rate is needed, the tube is stretched by pulling the wire, so that a fluid can flow between the tube and the inside surface of a heat transfer pipe, and heat can be exchanged between the fluid and the inside surface of a heat transfer pipe. When the heat transfer rate is decreased, the wire is loosened to restore the deformation of a tube, so that the tube is closely contacted to the inside surface of a heat transfer pipe, resistance is given to the heat transfer surfaces, as a result the heat transfer rate can be decreased. The value of resistance to heat transfer surface can be determined by choosing the thickness and material of a tube to be inserted. The same effect can be expected when a value of resistance to heat transfer surface in an arbitrary part is changed and is set by moving the inserted tube to the longitudinal direction of a heat transfer pipe instead of stretching it.

Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To perform high-speed access by simple hardware constitution by providing a comparison means for comparing an address at present held by a latch means with the address held in the past. SOLUTION: In the inside of a control ASIC 102, a register for holding data one time before the data of transparent latches 107 and 109 are respectively changed is provided. A CPU 101 performs comparison with a corresponding resister every time ALE signals are asserted and judges whether or not page mode access is possible. That is, in such a manner, the comparison means is attained. Then, since the high-speed access in the pertinent mode is appropriately possible in the case that access by a page mode which is a high-speed access mode is possible and the access is possible at a normal speed even in the case that the access by the page mode is not possible by a comparison result, the average access time of the entire memory is shortened.
