Title: X-ray tube device and manufacture of housing for x-ray tube device
Inventor: TAMURA HISAAKI
IPC: H05G1/04
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To prevent a deformation of a housing and eliminate a change of the spatial intensity distribution of X-rays, by making a housing of a X-ray tube device with an alloy containing ceramic powder and using silicon carbide for ceramic powder. SOLUTION: A X-ray tube device 10 has a housing 11 cast from aluminum casting allow containing silicon carbide(SiC), and this increases structural strength of the housing 11. Aluminum casting alloy, which contains 30% silicon carbide, has a thermal expansion coefficient of about 66% of that of aluminum casting alloy itself and is a little superior in thermal conductivity. The housing 11 is constituted of a left side structure 11L and a right side structure 11R cast nearly cylindrically using an aluminum casting alloy containing 30-40% silicon carbide as ceramic and a nearly cylindrical protection lead 11Pb provided between the structures 11L and 11R consisting of lead that prevents a leakage of X-rays. This enables many hours use under a heavy current load.

Title: Encoder
Inventor: SHIGESATO TATSURO
IPC: H04N19/00
Filed: 1986-01-13
Abstract: PURPOSE:To decrease the deterioration in picture quality when many low-order digits are missed by adding a dither (pseudo random number) to a quantized number of a picture, separating the result into the high-order digit and the low-order digit and sending them. CONSTITUTION:After a dither from a dither pattern generator 3 is added to n-bit picture element information from an input 1, the result is separated into high-order digits (n-m) bits and low-order digits (m) bits by a separator 4, they are subjected to error correction coding by error correction encoders 5, 6 respectively and the result is sent to a transmission line 7. The high-order digit passed through the transmission line 7 is inputted to an error correction device 8, where the information is subjected to error correction and inputted to an integrator 10. When no error is detected from the low-order digit by an error detector 9, the result is sent to the integrator 10 as it is, and if any error is detected, the information is replaced into an m-bit specific pattern (e.g., 2<m-1>) and the result is sent to the integrator 10. The signal decoded into n bits by the integrator is subjected to subtraction of dither from a dither pattern generator 11 and the result is outputted (13). Then even when many low-order digits are missed, no false profile is caused and the deterioration of picture quality is suppressed.

Title: Silver halide photographic sensitive material and image forming method
Inventor: MIYAZAWA KAZUHIRO
IPC: G03C1/035
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To provide the high max. density and low min. density at and under a high temp. and high humidity and to make it possible to lessen the generation of stains when dyestuff images are preserved by specifying the silver chloride content of a photosensitive silver halide to specific molar % or above. SOLUTION: The silver chloride content of the photosensitive silver halide of the silver halide photographic sensitive material having at least one color image forming layer contg. the photosensitive silver halide and dyestuff donating materials which release diffusive dyestuffs when reduced on the base is specified to >=90 mol.%. Single or plural kinds of silver halides may be used in combination for this photosensitive material. If silver chlorobromide, silver chloroiodobromide, silver chloroiodide, silver chloride, etc., having the silver chloride content of >=90 mol.% are used, the influence of bromide ions and iodide ions acting as catalyst poisons of amplification development processing is small and, therefore, the high max. density and low min. density may be attained with the short amplification development processing time. The generation of the stains is thus lessened.

Filed: 1995-01-17
Abstract: PURPOSE: To recongize the growth of a specific suspended matter without requiring manual operation by comparing the optical intensity of wavelength characteristic in a suspended matter to be identified with the optical intensity of the other wavelength. CONSTITUTION: Light emitted from a light emitting object floated on a water surface is converted into parallel light rays through a camera lens 1 and a 1st relay lens 2. Then only light with specific wavelength is transmitted through an interference filter 3 and an image is formed on picture elements in a video camera 4 through a lens of the camera 4. The formed picture element information is sent to a personal computer 5 as a video signal, processed in the computer 5 and displayed on a monitor screen 6. The computer 5 compares the optical intensity of respective filters for the picture information transmitted through the two filters and a previously set specific suspended matter (e.g. water-bloom) with a data base of an 'water-bloom' area to judge whether each part in the picture is an 'water-bloom' area or not and displays a final result on a monitor 6. Consequently the states of respective places in an water area can be grasped by a management office or the like.
