摘要： PURPOSE:To improve heat conductivity for preventing an excessive temperature rise of a helix by forcing a member having heat conductivity higher than that of a vacuum outer casing to make surface-contact with the inside face of a vacuum casing in addition to a plurality of dielectric-made helix supporting rods and also fixing said member to said inside face by soldering or welding on a penetrating hole part. CONSTITUTION:A helix 5 is arranged inside a vacuum casing 4 along a tube axis so as to be supported and fixed by a plurality of dielectric-made helix s rods 6. Between respective mutual helix supporting rods 6, metal pieces 7 having higher heat conductivity than that of the vacuum casing 4 are arranged. These metal pieces 7 are so formed as to be laid along the inside of the vacuum casing 4 to come in mutual face contact in a wide area. Further, the metal pieces 7 are fixed vacuum-tightly on the vacuum casing 4 by using penetrating holes 8 drilled in places in contact with metal pieces 7 by soldering or welding. Thereby, a radiation effect from the helix 5 to the vacuum casing 4 is excellent thus to suppress temperature excess at the helix 5 so as to obtain a stable operation characteristic.

摘要： PURPOSE:To reduce deviation of beam landing and improve picture color purity by attaching magnetic field control elements on the inside near four corner parts of a magnetic shielding body while magnetically combining therewith and their idle ends are located on the side of a color selection electrode to the orthogonal direction to a tube axis. CONSTITUTION:Magnetic field control elements 24 are attached on the inside near four corner parts of a magnetic shielding body 22 while magnetically combining therewith and their idle end parts 26 are located on the side of a color selection electrode 4 to the orthogonal direction to a tube axis. Then, even when a picture tube is set up to the east or to the west, a component Bz in the tube axis direction of a leakage magnetic field to an electron beam passing region of an external magnetic field such as earth magnetism can be increased, and said Bz and a vertical axis speed component accompanying deflection of an electron beam can cancel deviation of beam landing. Further, a vertical axial component (By) of the leakage magnetic field can be decreased while similarly cancelling deviation. Thereby, deviation of beam landing can be reduced to obtain a picture having good color purity.

摘要： PURPOSE:To remove foreign objects such as dust, etc., sticked to the surface of a jacket with the move of a shutter by providing a driving means in a magnetic disk cartridge. CONSTITUTION:Crimping parts 217a and 217b of a clip 211 get contact with ribs 231a and 231b to be formed in the internal part of a magnetic disk cartridge 100 and by these ribs 231a and 231b, the crimping parts 217a and 217b are pushed to a magnetic disk 121 side and crimp the end parts of the magnetic disk 121. In such a state, since the clip 211 is moved by a slide pin 301, the magnetic disk 121 is rotated by a prescribed amount. A shutter 151 opens head inserting ports 103 and 113 with the insertion of the magnetic disk cartridge 100 into a drive device. At such a time, the foreign objects such as dust, etc., sticked onto the surfaces of jackets 101 and 111 of the cartridge 100 fall down from the head inserting ports 103 and 113 onto the surface of the magnetic disk 121 by the end part of the shutter 151.

摘要： PURPOSE:To form patterning of uniform thin films with good productivity over the large region by ingeniously utilizing the diffraction effect of light and the properties of a photosensitive resin layer. CONSTITUTION:The thin film to be patterned is formed on a substrate 13 and after the photosensitive resin layer is installed on this thin film, a photomask 31 formed with light opaque patterns is disposed on this photosensitive resin layer. The light from a light source is focused and exposed at the further side of the photosensitive resin layer and the photosensitive resin layer is developed to form the resist patterns smaller than the light opaque patterns. The thin film is etched by using the resist patterns. The registration of the photomask, etc., are facilitated in this way; in addition, the use of an integral exposing device, etc., is possible and, therefore, the inexpensive patterning with the good productivity is executed.

摘要： PURPOSE:To easily find a cracked bulb by giving a shock to the bulb, detecting a sound wave caused by friction of the cracked part and transmitted to the inner part of the bulb, thereby the presence of the crack of the bulb. CONSTITUTION:A bulb 7 is provided so that a panel 7a is put upside and opposed to a hummer 18 and a funnel 7b is put downside to oppose the opening part 7d on the lower end of its neck part 7c to the opening 25 of a sound conducting pipe 26. An air cylinder 19 is operated to tap a hummer 18 on a panel 7a which is a part of a bulb 7, whereby a shock is given to the bulb 7. When the shock is given to the bulb 7 of cracked glass, ultrasonic waves are generated by the friction of the cracked part. Of the ultrasonic waves generated by the crack of the bulb 7, the ultrasonic wave transmitted to the air in the bulb 7 is introduced from the opening part 7d of the neck part 7c which is the only outlet to the outside of the bulb 7, transmitted from the sound conducting pipe 26 to a sound wave detector 27, and detected by a judging device 28, which then outputs an alarm.

摘要： PURPOSE:To correct a coma aberration without producing a neck shadow on a screen, by providing auxiliary coils which generate a magnetic field deflecting a center beam in the same direction and which at the same time generate a magnetic field deflecting a pair of side beams in the reverse direction, against the deflection direction of a deflection magnetic field generated by the 2nd deflection coil. CONSTITUTION:At the electronic gun 4 side end portion of a deflection device 5, a pair of auxiliary coils 33, 33 are provided in an up and down direction meeting at right angles with the arrangement direction of three electronic beams 15B, 15G, 15R as if to pinch a horizontal surface where these three electronic beams 15B, 15G, 15R pass. These auxiliary coils 33, 33 generate against the center beam 15G a pin cushion form magnetic field 36a which is in the same direction with the barrel form perpendicular deflection magnetic field 13 of a perpendicular deflection coil, and can generate against the pair of side beams 15B, 15R a pin cushion form magnetic field 36b which is in the reverse direction. As a result, a coma aberration is corrected by acting upon a direction that cancels the action by which barrel form perpendicular deflection magnetic field 13 of the perpendicular deflection coil affects the three electronic beams 15B, 15G, 15R.

摘要： PURPOSE:To eliminate a flicker on a display screen due to the asymmetry of the current-voltage characteristic of a nonlinear resistance element which is connected between mutually adjacent display picture element electrodes by constituting the nonlinear resistance element in reverse structure. CONSTITUTION:A nonlinear resistance element 14 for the display picture element electrode 12 of a part A has its lower metal 15 connected to a wiring electrode 13 and its upper electrode 17 connected to a display picture element electrode 12, and nonlinear resistance element 14 for the display picture element electrode 12 of a part B has its upper metal 17 connected to the wiring electrode 13 and its lower metal 15 connected to the display picture element 12. Thus, the nonlinear resistance elements 14 connected between the mutually adjacent picture element electrodes 12 are in the reverse structure, so even if the current-voltage characteristics of the nonlinear resistance elements 14 have some asymmetry between the positive and negative directions, the effect is canceled between the adjacent picture element electrodes 12 to eliminate the flicker on the display screen.
