Title: Color cathode-ray tube
Inventor: OOYAMA KOUJI
IPC: H01J29/32
Filed: 1994-10-28
Abstract: PURPOSE: To prevent the deterioration of brightness of a green phosphor layer, improve white uniformity without exerting influence on a visual field angle, and improve contrast by mixing/adding a green pigment in/to a black film, and stopping formation of a green pigment layer on the green phosphor layer. CONSTITUTION: Black films 8 having a space part are formed in red, green and blue phosphor forming positions on an inside surface of a panel 2, and graphite in which a green pigment is mixed is used as the films 8. After a red pigment layer 9 and a blue pigment layer 10 being filters are formed in red and blue phosphor forming positions, respective phosphor layers 4a, 4b and 4c are formed in the red, green and blue phosphor forming positions, and a fluorescent screen is constituted. Therefore, the deterioration of brightness is prevented, and a well-balanced white image is obtained, and contrast is improved. When a phosphor does not emit light, external light is absorbed in a well balanced condition, and a black body color is obtained.  Red and blue phosphor layers in which respective pigments are mixed may be formed in a covering shape in red and blue phosphor layer forming positions.

Title: Double swing bend test jig
Inventor: TSUJI OSAMU
IPC: G01N3/18
Filed: 1984-12-14
Abstract: PURPOSE:To apply a load to four points of a test piece even under a superhigh temperature, by applying an alternating load near length-wise both ends of the test piece with the first load mechanism and the one to two intermediate points thereof with the second load mechanism. CONSTITUTION:When a load body 5 is pulled downward to operate, a test piece 4 is dragged downward and a retaining rod 26 is dragged downward with a pair of rollers 20 supporting the test piece 4. With the reduction of a coil spring 30, a pressing force acts on an overhung 22 to move a load body 17 downward. As a result, a specified alternating load is applied evenly to two intermediate points of the test piece 4. Then, when a double swing bend test jig having the test piece 4 is arranged in a heating furnace 38, a specified alternating load can be applied to four points of the test piece 4 with first and second load mechanism. Thus, the jig thus obtained can withstand sufficiently long service when a test is done under a superhigh temperature.

Filed: 1984-12-18
Abstract: PURPOSE:To attain microwave oscillation even when a transistor (TR) with a small gain by providing a dielectric resonator having a power distribution function and a function of a band-pass filter to a feedback circuit. CONSTITUTION:The dielectric resonator 6 is coupled magnetically with microstrip lines 2, 3 at the input and output sides to form a band-pass filter. Then a part of oscillated output power is fed back to the input side of a TR1 via the microstrip line 2 at the input side and the rest of the oscillated output power is outputted to an output terminal 7 via the microstrip line 3. Thus, the dielectric resonator 6 is used as a power distributor and a band-pass filter in common, and since the loss in the feedback circuit is the loss as the band-pass filter and the loss of the microstrip lines 2, 3, even when the TR1 having a comparatively small gain is used, a microwave is oscillated sufficiently.
