IPC: C25B11/06
Filed: 1985-09-05
Abstract: PURPOSE:To decompose water by visible radiation by coating a visible-region n-type semiconductor with the film of a specified high molecular complex modified by allowing a specified medium and stabilizing the semiconductor in the title method wherein the semiconductor is used. CONSTITUTION:The film of a high molecular complex having tris(2,2'-bipyridine) ruthenium(II) complex as a pendant group is coated on the surface of a visible- region n-type semiconductor electrode. Group VIII metal in the periodic table or its salt is allowed to coexist in the film, the modified electrode is immersed in an aq. soln. of an electrolyte and visible radiation is irradiated on the electrode surface. Consequently, water is decomposed, O2 is generated on the semiconductor electrode and H2 is generated on the counter electrode. A complex shown by the formula (M is the monomer of styrene, acrylic acid, etc., x-z are the molar fraction of the repeating unit, x=0.01-0.98, y=0-0.9, z=0-0.98 and x+y+z=1) is exemplified as the high molecular complex.

Title: Method for color printing
Inventor: YAMADA TOSHIYUKI
IPC: G06F3/12
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To reduce an information amount of color image information fed to a color printer and reduce memories by carrying out color printing without deteriorating color expression performance represented by gradation efficiency with the use of the color image information of a low resolution which is a fraction of a resolution of the color printer. SOLUTION: In a color printer, video signals are received for every color and a latent image is formed on a photosensitive belt 300 through scanning with a laser light 306a. Corresponding color toners are adhered by a developing part 301, thereby forming a development page 304. The development page 304 is transferred to a paper 307 via a transfer drum 302. At this time, color image information is formed with a low resolution which is 1/n (n is an integer) a resolution of the color printer. The low-resolution color image information is converted to limited gradational values of not smaller than two or three pixels to be sent to the color printer from color information of one pixel, and sent to the color printer to achieve color printing.

IPC: H03M13/00
Filed: 1991-08-07
Abstract: PURPOSE: To improve the run time performance of cyclic redundant check(CRC) calculation by simultaneously substituting the approach of a look-up table(LT) of one byte for the approach of respective bits of CRC delimitation. CONSTITUTION: In the operation of a CRC word consisting of sixteen bits, a data latch 18 inputs the bit sequence 16 of input data and simultaneously supplies data 17 to an COR gate 20 in each eight bits. The gate 20 receives a maximum digit byte CRC inverted high signal 12 through a latch 22 and supplies its XOR operation result 24 to a high LT 26 and a low LT 28. An XOR gate 32 inputting an 8-bit output 30 from the LT 26 receives an 8-bit output CRC inverted low signal from the LT 28 through a latch 34. The operation result of the gate 32 becomes the CRC inverted high output 12. Consequently the run time performance of CRC calculation is improved.
