Inventor: KOIKE NORIO
IPC: H01J29/20
Filed: 1986-11-14
Abstract: PURPOSE:To obtain a color picture tube of high resolution and high brightness and to prevent yellow directional color shifting at the peak of brightness by using ZnS:Ag, Al for a blue luminous phosphor and forming an electron gun into the one of a long focal point lens. CONSTITUTION:A blue luminous phosphor layer composing a fluorescent screen 13 is made of Ag and Al as active agents and a ZnS:AgAl phosphor containing Ag of 0.055 wt% to 0.085 wt% in a mother material. An electron gun 17 is formed in such structure that a prescribed voltage is applied to a required electrode through a resistor 21. Hence, when a spot diameter of electron beams incident to a fluorescent screen is made small by a long focal point lens system, resolution can be upgraded. when properties of the blue luminous phosphor are utilized to combine this tube with the electron gun, high brightness can be obtained and color shifting can be prevented from occurring at the peak of white brightness.

Title: Heat-sensitive ink-transfer sheet
Inventor: NAKADA SHINOBU
IPC: B41M5/26
Filed: 1985-11-29
Abstract: PURPOSE:To execute the multi-color or full-color recording of a good quality on even the paper to be transferred of 200sec max. in smoothness as well as a postcard, by forming an ink-transfer stabilization layer at the top of each three colors on an ink-transfer sheet aside from the ink layer of three colors. CONSTITUTION:The ink-transfer stabilization 3 part of an ink-transfer sheet 1 receives the heat of a thermal head in a state where it is piled on the paper to be transferred and the ink-transfer stabilization layer 3 is transferred. In that case, because the ink-transfer stabilization layer 3 is better in fluidity than an ink layer 4 the surface depressed part of the paper to be transferred is filled, the smoothness as the paper to be transferred increases and at the same time, the adhesion to each color becomes good. Then, the paper to be transferred to which the ink-transfer stabilization layer 3 is transferred returns to the initial position. At the same time, the top of the yellow 4a of the ink- transfer sheet 1 is taken out and the ink of the yellow 4a is transferred to the ink-transfer stabilization layer 3 on the paper to be transferred. Thereafter, by repetition of the same operation to a magenta 4b and a cyan 4c, the color recording of a good printing quality can be executed on the paper to be transferred of a low surface smoothness.

Filed: 1987-10-27
Abstract: PURPOSE:To check a brazing filler metal intruding to a sintered member side by heating the sintered member set up at a rotary center side and the refined member set up at the outer part side thereof by integrally rotating them in the state of interposing the brazing filler metal therein.

Filed: 1993-10-05
Abstract: PURPOSE:To maintain coherence and to decrease speckle noises by using luminous fluxes which are low in space coherence and introducing object waves and reference waves to a hologram forming surface in the state of maintaining the coherence by these luminous fluxes. CONSTITUTION:The luminous flux is introduced in such a manner that the optical axis is perpendicular to a diffraction grating 16 in a reference illuminating optical system. The irradiation plane to the diffraction grating 16 aligns to the perpendicular section of the luminous flux before splitting. Since the diffraction grating 16 and the hologram plane are parallel, the irradiation plane on the diffraction grating 16 is maintained as it is and becomes the irradiation plane in a hologram forming position 1. The optical path length on the optical axis is then equaled to the respective points off the optical axis. The optical path lengths in the respective part positions in the irradiation plane are respectively equalized by disposing a correction prism 17 having the sectional shape on the optical axis symmetrical with the shape of a triangular prism 3 on the upper part of the diffraction grating 16. Further, both optical path lengths are adjusted to be admitted within the coherent range by disposing an optical path adjusting means 19 in the optical path of an object illuminating optical system in order to adjust both optical path length lengths of the object waves and reference waves.

Filed: 1984-12-21
Abstract: PURPOSE:To effectively prevent waving of a chain by shortening a distance between fulcrums and increasing the curvature of a sliding contact member when looseness of the chain increases. CONSTITUTION:A rod 31 extends freely to the maximum projecting position when spring force P is greater than external force Q and it remains stopped at the projecting position when the external force Q is greater than the spring force P. Therefore, one end of a rocking material 14 is normally pressed by a pressing means 18 at substantially constant spring force P and because a sliding contact material 17 is easily curved and elastically transformd, the sub stantially total length of the material 17 makes uniform contact with a chain 12. According to such constitution, the sliding contact material 17 is not retreated by the reaction force of the chain 12, therefore waving of the chain 12 can be suppressed.
