Title: Scanning system of thyristor-type channel switch
Inventor: YOSHINO HARUYUKI
IPC: H04Q3/52
Filed: 1977-12-28
Abstract: PURPOSE:To realize a scanning system of a thyristor channel switch which absorbs on-state resistance deviation, by switching successively only one constant-current power supply path in a row direction to form always a constant-current value path. CONSTITUTION:Constant-current controller 7 and constant-current switch 8 supply the DC bias to a channel. Constant-current switch 8 is controlled by counter 9, decoder 10 and timing circuit 11 and switches only one path for the selectrd constant current in the row direction. Then, register 6 accumulates matrix information from the control system, by which it is decided whether the row should be selected or not, as a decode, and selection gate 5 operates AND between register 6 and decoder 10 to transmit successively the same information to plural outputs at the output timing of decoder 10, thereby absorbing the on-state resistance deviation of a thyristor.

Title: Picture display device
Inventor: MORIYAMA YUICHI
IPC: H01J31/12
Filed: 1988-06-29
Abstract: PURPOSE:To reduce the intensity difference on a screen due to the vibration of linear cathodes by providing two vibration preventing bodies for the linear cathodes on a cathode-stretched plane and fitting one of them on the opposite side so as to pinch the linear cathodes between insulating guides. CONSTITUTION:If linear cathodes 10 start to be vibrated by the drive pulse or external vibration, a vibration preventing body 13a provided on one side serves as a node when the cathodes 10 are swayed to the vibration preventing body 13a side, a frequency different from the single chord vibration is obtained as shown by B and C, it suppresses the initial vibration expansion. Damping occurs due to the friction between the vibration preventing bodies 13 and the linear cathodes 10 to stop vibration. The distance between a vibration preventing body 13b on the other end and a guide 9 differs from that between the vibration preventing body 13a and a guide 9, thus a different frequency is obtained, and it is more effective. The vibration preventing body 13b on one side is inclined from the perpendicular direction to the linear cathodes 10, thus resonance frequencies of individual linear cathodes are different, the resonance by external vibration is not applied to all linear cathodes 10.

IPC: G01N21/17
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To utilize a laser beam as a large-area irradiation system, where a light intensity distribution is uniform by inserting a converter for dividing light at a constant interval and a diffusion plate for uniformly dispersion the transmission light halfway through an optical path. SOLUTION: A laser beam 2 from a laser 1 enters a micro pattern converter 3 in an optical path. The micro pattern converter 3 is composed by an arrangement, where prism-like shapes with sufficiently small and different inclination for the diameter of the laser beam 2 are regular, and the light of the laser beam 2 is divided into circular, rectangular, square shapes or the like with a number of lines with a constant interval. A divided and spread beam 4 is applied to a diffusion plate 5. With light having passed through the diffusion plate 5, all spots are diffused and mixed to obtain a luminous flux with a uniform intensity distribution. For obtaining light of uniform intensity widely in the direction of the light axis, it is effective to insert a lens 7 halfway. The diffusion plate 5 can be produced by polishing the surface of glass with fine sand.
