IPC: B41J2/525
Filed: 1986-10-21
Abstract: PURPOSE:To attain small capacity conversion table by inputting a color difference signal and providing a conversion table outputting a hue signal and a saturation signal. CONSTITUTION:An RGB signal is converted into a luminance Y, color difference signals R-Y, B-Y by a matrix circuit 1.

Filed: 1987-09-30
Abstract: PURPOSE:To reduce the load of the control software and to easily secure the real time properties by allocating the switching information corresponding to the counter circuits that should be started simultaneously to a memory means where the accesses are possible at one time. CONSTITUTION:When both counter circuits 2 and 3 are started at one time, a CPU 11 writes the data 'XXXXX11' into an address (c) of a register circuit 14 based on the information given from a RAM 13.

Title: High-sensitivity fluorescent x-ray gas analyzer
Inventor: KAMESHIMA YASUBUMI
IPC: G01N23/223
Filed: 1986-10-21
Abstract: PURPOSE:To make qualitative and quantitative analyses of trace impurities with high accuracy even with a gas having danger by providing solid-state element X-ray detectors to the side wall of a gaseous sample sealing tube and using synchrotron radiation light as a light source for excitation. CONSTITUTION:The synchrotron radiation light 2 taken out of a storage ring 1 passes a beam line and an aperture 3 having a prescribed diameter and thereafter, said light enters the gaseous sample sealing tube 4 made of beryllium. Plural pieces of the solid-state element X-ray detectors 7 of an energy dispersion type are disposed to the side wall of the sealing tube 4 to detect the characteristic X-rays generated from the atoms in the gaseous sample. The signals received by the detectors 7 are subjected to pulse height analysis in a multichannel analyzer 9 by which a radiation energy distribution is measured. Since a gas introducing cock 5 and a discharge cock 6 are strictly vacuum-sealed, the leakage of toxic gases during the measurement is obviated. Since the photodetecting surfaces of the detectors 7 are disposed perpendicularly to polarization vector 8 of the incident beam, the background by the scattered light is extremely minimized.
