摘要:
In the structure of the present invention, there can be provided a cathode ray tube in which deviation in the trajectory of the electron beams by the leakage magnetic field from the mask frame (1) is decreased by using a polygonal mask frame (1) in which the relative magnetic permeability of longer side members (31) out of two side members adjacent to each other at the joint portion of the mask frame (1) is the same as or larger than the relative magnetic permeability of the other side members (21). Thus, the significance of the present invention in industrial terms is large.

An internal magnetic shield includes a pair of opposing long side walls (1), a pair of opposing short side walls (2), and an opening (3) enclosed by these side walls in the center. The short side walls (2) are provided with notches (4) having a substantially home-plate shape. This configuration can reduce mislanding of an electron beam on the entire screen and easily balance the amount of mislanding due to geomagnetism in the tube-axis direction and in the horizontal direction perpendicular to the tube axis. As a result, a cathode ray tube capable of displaying images without displacement and unevenness of colors can be provided.
摘要:
A cathode ray tube is provided, in which the flatness of a tension mask constituting a color-selection mechanism is maintained by a suitable stretching force, while with the tension mask, the influence of external magnetic fields, such as the terrestrial magnetism is suppressed, and the shifting of the electron beam is reduced. A tension mask made of a magnetostrictive material is used, the tension mask is stretched by a stretching force in a range maintaining the flatness of the tension mask, and the direction and strength of the stretching force are set such that vertical magnetic permeability of the tension mask increases, due to a magnetoelastic effect caused by the stretching force in the magnetostrictive material of the tension mask.
摘要:
A cathode ray tube including an internal magnetic shield in the shape of a hollow rectangular frustum including two long sides opposite to each other and two short sides opposite to each other, having an opening at its top and bottom attached to a mask and a frame. Each long side has a long side extension at a horizontal center located at the top of the internal magnetic shield where an electron beam enters the internal magnetic shield. The long side extensions enable the magnetic shield to reduce the deviation of an electron beam within the magnetic shield caused by an external magnetic field such as that caused by terrestrial magnetism.
摘要:
An inner magnetic shield is provided that reduces mislanding lengths due to electron beam distortion caused by external magnetic fields such as terrestrial magnetism, thereby reducing the occurrence of drifted or uneven color throughout an entire display screen. The inner magnetic shield is of a tube with a plurality of side surfaces, and is provided with at least one skirt (37) that extends to the vicinity of a spanning member (41) at a location where the inner magnetic shield is not in contact with a holding member (42). The skirt (37) is magnetically coupled with the spanning member (42).
摘要:
In the disassembling method of a display device of the present invention, the display device has a display panel, and metal plate unit having a panel member formed of a chassis member disposed on the back surface of the display panel and a circuit board as an electric circuit member attached to the chassis member through an attaching member. The disassembling method has a mounting step of mounting metal plate unit on stage whose tilt angle can be adjusted by mechanism section and a cutting step of cutting the attaching member in parallel with the surface of stage with saw blade that abuts on the attaching member by the own weight of metal plate unit based on the tilt angle of stage.
摘要:
An image processing apparatus implements a plurality of functions and includes a display device. The plurality of functions include a function belonging to a first group and a function belonging to a second group. A selection accepting unit accepts selection of any of the first group and the second group. A first display control unit causes the display device to display on a display screen, a plurality of first keys corresponding to respective functions belonging to the first group, regardless of which of the first group and the second group has been selected. A second display control unit causes, when the second group is selected, the display device to display in a second region of the display screen other than a first region where the first keys are displayed, second keys corresponding to respective functions belonging to the second group.
摘要:
A method and apparatus for efficiently removing a dissimilar material as part of a recycling process, which are free of problems in the terms of worker safety and the work environment, are provided. With the apparatus of the present invention, a working unit is operated to move a blade unit while pressing a plastic product from the outside thereof to punch out the dissimilar material.
摘要:
In a fluorescent X-ray analysis method, a sample (1) is set on a sample stage (2) on an upper side of an X-ray irradiation chamber (7) and a sample cover (6) is closed from the upper part of the sample (1) to surround the sample (1), and then, a lower plane of the sample (1) is irradiated with X-ray for analysis. When the sample (1) is set on the sample stage (2) and the sample cover (6) is closed, a cover detecting means (8) detects that the sample cover (6) is closed and X-ray is automatically projected from an X-ray source (3) to start analysis.
