摘要： PURPOSE:To reduce luminance shortage, luminance fluctuation, and irregular color by keeping constant a distance between electrodes of a plurality of electrode groups with respect to an electron flow to be emitted from a linear heat cathode. CONSTITUTION:In a plane tape display, first control electrode groups 9 and second control electrode groups 10 in a control electrode unit 6 for controlling an electron flow are formed approximately in parallel with respect to an electron emitting source for emitting an electron. A distance between the electrodes is kept constant by an insulative bonding layer 20 of a dot type or the like. Consequently, since a stress produced by heat generation during operation or in a manufacturing process can be alleviated and electrode strain can be restrained, it is possible to prevent the deformation or breakage of the electrode.

摘要： PURPOSE:To provide a titled device which requires less floor area and improves operation and processing efficiency in laser cutting by working a work by means of multi-heads for changing over optical axis scanning in one way and a working table moving orthogonally therewith, and providing a sorting mechanism for parts and scrap. CONSTITUTION:NC-programmed working is performed with a laser head 3 scanning in an X-axis direction and a material 6 to be worked on a table 4 moving in a Y-axis direction. The head 31 used exclusively for a small hole, a short focusing head 32 for a thin sheet, and a long focusing head 33 for a thick plate are changed over when the NC program of a mirror 11 according to the purpose of use is changed. Dross, etc. is received by a roller 13 and is dropped onto, for example, a left belt conveyor by a sorting plate 12. The parts completed of working are dropped onto a right side belt conveyor by the plate 12 upon opening of a taking out plate 9. The operating efficiency is improved by the change- over of the working heads and the mechanism for handling the dross and parts, and the floor area for the installation is thereby decreased.

摘要： PURPOSE:To form a phosphor pattern without using a shadow mask or an auxiliary lens by detecting the fluorescent quantity generated from phosphors absorbing an electron beam when the electron beam is radiated, and correcting the radiation position of the electron beam in response to the position of the measured black matrix. CONSTITUTION:The fluorescent quantity generated from phosphors excited by an electron beam 15 when the electron beam 15 is radiated is detected to measure the position of the black matrix 2, and the radiation position of the electron beam 15 is corrected in response to this position. The position of the black matrix 2 is detected by utilizing the face that the fluorescent quantity generated from phosphors excited by the electron beam 15 differs extremely by the presence or absence of the black matrix 2, and a phosphor pattern is directly exposed while the radiation position of the electron beam 15 is controlled. The phosphor pattern of a color cathode-ray tube which has clear fluorescent characteristic and allows the mixed production of various cathode-ray tubes can be obtained.

摘要： PURPOSE:To facilitate stable exposure of the wall surface of a cylindrical hole by a method wherein both the incident beam applying part of a resist layer on the wall surface of a cylindrical hole to which a converged beam is applied directly and the reflected beam applying part of the resist layer to which a reflected beam is applied are exposed simultaneously. CONSTITUTION:The scanning position and scanning speed of a converged electron beam 20 which is emitted from a cathode 17 and converged through a converging coil 19 are controlled by deflection coils 14. Under such conditions, the beam 20 is applied onto the whole region of the open surface 21 of the cylindrical hole 2 of a substrate 1 in such a manner that the direction of the beam 20 has an inclination angle against the normal of the opening surface 21. As a result, the incident beam applying part 22 of a resist layer 3 covering the wall surface of the hole 2 to which the beam 20 is applied directly and the reflected beam applying part 23 of the resist layer 3 to which the beam reflected by the resist layer 3 of the incident beam applying part 22 is applied are exposed simultaneously. With this constitution, the substrate 1 having the cylindrical hole 2 is exposed efficiently and stably without creating a shaded part.

摘要： PURPOSE:To expose the wall surface of a through-hole stably without increasing the pattern width of flat surface by a method wherein the wall surface is exposed to a converged beam entering from one opening of the through-hole and a reflected converged beam entering from the other opening. CONSTITUTION:An electron beam emitted from a cathode 17 is converted into a converged electron beam 20 in accordance with a signal transmitted from a pattern generator 11. The scanning position and scanning speed of the beam 20 are controlled by deflection coils 14. Under such conditions, the beam 20 is applied for the purpose of scanning onto a substrate 1 whose whole surface is covered with resist 3, which has a reflection plate 23 at its bottom and which has a through-hole 2. As a result, the incident beam applying part 22 of the resist 3 on the wall surface of the hole 2 to which the converged beam 20 is directly applied and the reflected beam applying part 24 to which the beam reflected by the reflection plate 23 is applied are exposed simultaneously. With this constitution, the substrate having the through-hole can be exposed efficiently and stably without creating a shaded part.
