Title: Image forming device
Inventor: KITAKUBO HIDEO
IPC: G03G15/01
Filed: 1990-09-11
Abstract: PURPOSE:To attain the simplification of the assembling and maintenance of a density detecting sensor, etc., and the accuracy of the density detection of a reference density pattern by arranging the density detecting sensor at the rear position from a transfer position. CONSTITUTION:When the reference density pattern AP is produced on the surface of a photosensitive body 3, the produced reference density pattern AP is detected by the density detecting sensor 73 arranged at the rear position compared with the transfer position from the photosensitive body 3 to an intermediate transfer medium 11. When the reference density pattern AP comes into contact with the surface of the intermediate transfer medium 11 and passes thereby, the surface of the intermediate transfer medium 11 is electrified to the same polarity as that of a toner image as the reference density pattern AP, so that electrostatically repulsing force occurs between the intermediate transfer medium 11 and the reference density pattern AP. Therefore, the toner of the sticking of the reference density pattern AP to the intermediate transfer medium 11 is minimized. Thus, the sensor is arranged at the rear position from the transfer position to simplify its assembling and maintenance, and simultaneously, the density detection of the pattern is surely carried out.

Abstract: PURPOSE:To ensure the treatment of sewage and particularly that of difficultly decomposable putrescible waster liquors containing org. halide, etc., in a proper way, and use a porous filter over an extended period of time by a method wherein untreated waste liquors are made to contact with the filter whose framework is formed of the porous body of a three- dimensional network and consists of at least one kind of metals Fe, Mn, Mg, Zn, Al and Ti, thereby subjecting contaminants in the waste liquors being treated to reductive decomposition for their removal therefrom. CONSTITUTION:Untreated waste liquors are made to contact with the filter whose framework is formed of the porous body of a three-dimensional network and consists of at least one kind of metals Fe, Mn, Mg, Zn, Al and Ti, thereby subjecting contaminants in the waste liquors being treated to reductive decomposition for their removal therefrom. For example, an aq. solution for dissolving oxide film is brought into contact with iron oxide film existing on the surface of a filter consisting of iron to remove such film therefrom in order to retain Fe<0>. Such a filter as this permits a uniform contact with harmful substances in the waste liquors being treated without causing the short pass thereof, resulting in an efficient film removal by decomposition. In the case of the filter consisting of the aforesaid metal other than Fe, the waste liquors are subjected to the reductive decomposition by the same reaction to be made free from the harmful substance.

Filed: 1993-09-02
Abstract: PURPOSE:To avoid deterioration in a voice signal by multiplying a window function with each segment of the voice signal at a sender side, matching the position of the voice signals and replacing a waveform of several preceding pitches at a receiver side. CONSTITUTION:A window function is outputted from a window function generator 3 while keeping a relation in which a timing signal and a bottom level of the window function are coincident. The window function and a voice signal subject to A/D conversion 2 are multiplied by a multiplier 2 and a position equivalent to a joint of segments is suppressed. The result of multiplication is alternately written in a 1st buffer 4 and a 2nd buffer 5 one frame each. The content of each buffer is alternately read and given to a D/A converter 7 as a scrambled signal and the result is led to an LPF 8. Since the vicinity of the joint of segments is smoothly suppressed, no waveform distortion around the joint is caused even when the signal is filtered by the LPF 8. At the receiver side, a similar waveform in the vicinity thereof is copied to the joint of segments to joint smoothly the signal waveform.

Title: Color filter substrate for liquid crystal panel and liquid crystal panel using the same
Inventor: SUMIDA SHIROU
IPC: G02B5/20
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent generation of uneven cell gap due to concentration of load to a part of spacer particles and disturbance of orientation of liquid crystal due to movement of spacer particles in a liquid crystal panel using a color filter substrate. SOLUTION: A liquid crystal panel is manufactured with a color filter substrate having no region where a lightproof layer 2 and color filter layers 31, 32, (33) overlap themselves, or even if such a region exists, it is limited to a minimum necessary for positioning in manufacturing the color filter substrate. All spacer particles 7 in a liquid crystal layer contribute to form a cell gap because differences in level between each region on an array substrate and a difference in level on the color filter substrate cancel with each other. Thereby the cell gap is kept uniform and besides movement of spacer particles 7 is prevented.
