摘要:
In an exposure step for forming a phosphor screen of a color cathode ray tube, correction lenses which are arranged between a light source and a panel are used in a state that a common correction lens which is used in common for three colors and three kinds of monochroic correction lenses are combined. The present invention can, in a flat-face-type color cathode ray tube, prevent the generation of the mislanding attributed to the difference in a wall thickness between a center portion and a peripheral portion of a panel thus improving the color purity.
摘要:
In a manufacturing method of a color cathode ray tube, as an exposure light source which is used in the exposure for forming a phosphor screen, an ultra-high pressure mercury lamp having an arc length of 35 to 60 mm is used. According to the present invention, it is possible to make an aperture shape of a black matrix film of a color cathode ray tube uniform and it is also possible to enhance the operational efficiency.

A correction filter used in the exposure for forming a phosphor screen includes three kinds of correction filters consisting of a grading filter, a monochroic local correction filter and a multi-color local correction filter. With the use of three kinds of correction filters, it is possible to improve the whiteness uniformity which may be degraded due to the wall thickness difference at the center and a peripheral portion of a panel portion of a flat-face-type color cathode ray tube.

The present invention is directed to an optical pick-up apparatus used for recording/reproduction of an optical disk, which comprises an optical pick-up (17) caused to undergo feed operation in the radial direction of optical disk (2), and for performing write or read operation of information signals with respect to the rotating optical disk, and a flexible printed wiring board (45) having one end portion (45a) connected to the optical pick-up, and the other end portion (45d) provided in a manner extended in the feed direction of the optical pick-up. The flexible printed wiring board includes a folded portion (45g) folded back toward the bottom surface portion side of the optical pick-up, and a bending displacement portion (45h) for allowing folded position of the folded portion to undergo displacement in a manner following the feed operation of the optical pick-up, wherein a slit (47) for escaping a projected portion (17b) projected from the bottom surface portion of the optical pick-up is provided at the folded portion.
摘要:
A cathode ray tube has a panel portion 1 with a phosphor layer 5 formed on its inner face, a neck portion 2 accommodating an electron gun 9, a funnel portion 2 for coupling the panel portion 1 to the neck portion 2 and a color selective electrode assembly 6 having a number of electron beam passing openings arranged opposite to the phosphor layer 5 with a space therebetween. The color selective electrode assembly is installed within the panel portion 1. An electron beam reflection film of a bismuth oxide thin film 6R having a bulk density of at least from 41 g/cm3, to 9.3 g/cm3, e.g., is formed on the face of the color selective electrode assembly 6 against which the electron beams 14 emitted from the electron gun 9 collide. The cathode ray tube is capable of displaying high density and high resolution image.

摘要:
A disc drive apparatus comprises a housing; a disc-holding unit that holds an optical disc in the housing; a disc-driving mechanism that rotates the optical disc held by the disc-holding unit; an optical pickup that writes signals in, and reads signals from, the optical disc being rotated by the disc-driving mechanism; and a pickup-moving mechanism that moves the optical pickup in a radial direction of the optical disc. The housing has an air-inlet port which is located above the optical disc held by the disc-holding unit and through which air is drawn from outside by virtue of an airflow that develops as the optical disc is rotated, and air-outlet ports through which air is discharged from the housing.
