    摘要： A cathode ray display tube has a magnetic shield comprising a mesh (60) of high permeability magnetic material such as mumetal covering the outer surface of its transparent faceplate (14) through which a display from a screen (16) is visible and which together with a magnetic shielding box (70) surrounding the remainder of the tube's envelope (10) inhibits extraneous magnetic fields entering the envelope and affecting the electron beam undesirably. The shielding arrangement is particularly useful with a flat tube having a relatively large area faceplate and using a low-energy scanning electron beam (32). The mesh (60) may be supported by one or more transparent members (66), and may be treated to enhance contrast of the display and also to act as a electromagnetic radiation shield.

    摘要： A colour cathode ray tube has an inner magnetic shield for controlling the magnetic field distribution internal of the tube. The inner shield is formed to have a pair of long side walls and a pair of short side walls provided along an inner wall of a funnel-shaped portion of the tube. Each long side wall has formed therein at least one elongated opening in each of the two regions divided by a centre of the long side wall. The openings may take the form of a triangular-shaped opening or they may be narrow generally rectangular slots.

    摘要： An image receiving tube device comprising a panel formed with a fluorescent screen, a funnel integrated with the panel, an electron gun installed in the funnel, a magnetic shield (1) for shielding electron beams (5) emitted from the electron gun from the external magnetic field, and a frame (2) holding the magnetic shield (1), wherein the magnetic shield (1) has a bend (20) that is bent toward the tube axis in the junction with the frame (2), and the thickness (T) of the bend (20) at the edge on the tube axis side is 0.08 mm or less. Reducing the thickness (T) reduces the number of electron beams reflected by an end surface (11) to reach the screen without being shielded by the frame (2), thus making it possible to suppress halation that tends to occur in an image receiving tube device having a high deflection angle.

    摘要： An electron emission display (1) includes first (10) and second (12) substrates facing each other, electron emission regions (20) to emit electrons and formed on the first substrate (10), and driving electrodes (14) formed on the first substrate to use in the control of the emission of electrons from the electron emission regions (20). Phosphor layers (26) are formed on a surface of the second substrate (12). An anode electrode (30) is placed on a surface of the phosphor layers (26). Spacers (32) are mounted between the first and the second substrates. Antistatic electrodes (34) are placed over the first substrate (10) such that the antistatic electrodes (34) are insulated from the driving electrodes (14), and electrically connected to the spacers (32).

    摘要： A cathode-ray tube (10) has an internal magnetic shield (18) and at least one contact spring (28) attached to the shield. The shield includes a land (31) with an outer edge (36) and an inner edge (35). The spring includes two portions, an improved clasp portion (42) attached to the shield at the land, and a contact leaf portion (44). The improved clasp portion includes a flat body (41) with a reverse bend hook (46) at a first end, and a latch (48) and a catch (43) at an end opposite to the first end. The hook engages the outer edge of the land, and the latch engages the inner edge of the land. The catch includes a bent end portion that forms an acute angle with the remainder of the catch. The bent end portion is positioned to engage the inner edge of the land if the spring is rotated about the hook. The leaf portion is connected to and extends from the latch.
