Title: Silver halide color photographic sensitive material
Inventor: SHIMAZAKI HIROSHI
IPC: G03C7/30
Filed: 1986-03-05
Abstract: PURPOSE:To enhance sharpness by incorporating a means for forming an unsharp positive image in combination with at least one of emulsion layers and a compound capturing the oxidation product of a color developing agent but not contributing to image formation. CONSTITUTION:A suitable means for forming an unsharp positive image is a low-diffusive compound for forming an unsharp positive image in combination with the silver halide emulsion layer for forming a color negative image, and containing a diffusion resistant coupler. Said compound is allowed to release a diffusion resistant dye having main absorption in the main absorption wavelength region of a color developing dye by the reaction with the oxidation product of the color developing agent. The compound does not react, or changes color in the area where the diffusion resistant coupler does not form a dye image. As a result, the color image formed by the coupler is reverse to that formed by said positive low-diffusive nonreacted or color changed compound, and an unsharp positive image is formed by its low diffusivity, thus permitting the obtained photosensitive material to be restrained from rise of the minimum density and enhanced in the gamma value.

Patent JP-H02229421-A (JP)
Title: Aligner
Inventor: YUI MASARU
IPC: G03F7/20
Filed: 1989-03-02
Abstract: PURPOSE:To bring a semiconductor wafer into close contact with a photomask by using a proper close contact force and to enhance a transcription accuracy without bending the photomask unnecessarily by executing an exposure operation while the semiconductor wafer is brought into close contact with the photomask by using a magnetic force by means of an electromagnet. CONSTITUTION:An electromagnet 6 is fixed to a position facing a peripheral part 4c of a through hole 4b in a mask holder 4 on the side of a wafer stage 2; when an electric current flows, the electromagnet 6 attracts a magnetic substance 5. A height of the magnetic substance and that of the electromagnet are selected in such a way that, when a semiconductor wafer is brought into close contact with a photomask, a slight gap is formed so as not to be brought into mutual contact. Even when the height of the magnetic substance and that of the electromagnet are irregular, the semiconductor wafer can be brought completely into close contact with the photomask. Since they are brought into close contact by using a magnetic force by means of the electromagnet, a close contact force can be adjusted easily by adjusting an electric current to be applied. As a result, an exposure operation can be executed by using an optimum close contact force. Thereby, it is possible to avoid that the photomask is curved unnecessarily.

IPC: H04N1/00
Filed: 1978-04-27
Abstract: PURPOSE: To simplify the correlation decision either the 1-dimensional or 2-dimensional encoding is given to the picture signals to be encoded, and thus to increase the compression rate for the compression encoding of the picture signals.  
     CONSTITUTION: The picture is scanned to obtain the picture signals for each scan line, and these picture signals are compressed with encoding. In this system, the displays of codes A∼Z are added to the picture element of the preceding scan line, and the information changing point for encoding is referred to as TR1. Then the preceding information changing point and one more preceding changing point are referred to as TP2 and TP3 respectively. And the displays of codes a∼z are added to the picture elements of K + 1 lines including the above mentioned three changing points. Thus, the correlation is estimated between information changing points TP1∼TP3 to be encoded and TP1∼TP3 of the scan lines which are sent in  advance. According to the estimated correlation, points TP1∼TP3 to be encoded or at least part of the encoding algorism of the information change picture elements corresponding to TP1∼TP3 is switched, thus carrying out the compression encoding for the picture signals.

Abstract: PURPOSE:To improve accuracy of judgement by judging that an exhaust gas component concentration sensor is in an active condition when an exhaust gas component concentration detected value exceeds the first predetermined value, however the sensor is in an inactive condition when a detected value is less than the second predetermined value (< the first predetermined value). CONSTITUTION:An engine 5 controls the air fuel ratio of mixture by letting a control circuit 20 control an air-fuel ratio control means such as a linear type electromagnetic valve 9 and the like based on the output from an O2 sensor 14 acting as an exhaust gas component concentration sensor when an air-fuel ratio feed-back control condition is satisfied. In this case, it is judged by the control circuit 20 that the O2 sensor 14 is in an active condition when an oxygen concentration detected value given by the O2 sensor 14 exceeds the first predetermined value. However, it is also judged that the O2 sensor 14 is in an inactive condition when the oxygen concentration detected value becomes lower than the second predetermined value smaller than the first predetermined value. In addition, said judgement is adapted to be formed when an engine idling is detected.
