Title: Driving method for fluorescent display tube and driving device
Inventor: MURAYAMA KOICHI
IPC: G09G3/12
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To enable suppressing finely leakage light emission caused by a spike noise without sacrificing luminance with simple constitution. SOLUTION: In a cathode potential switching process, a potential of a cathode 32 is adjusted to a second potential Vf2 being higher than a first potential Vf1 by 5-15 V during a period having the length over before and after of an anode potential switching process within a blanking period. Therefore, in an anode potential switching process in which a spike noise can be caused accompanied by switching of applying voltage to each of plural graphite layers 40, as a potential of the cathode 32 is raised to the second potential Vf2, even when a spike noise is caused, it is suppressed that a potential of a grid electrode 22 is higher than the potential Vf2 of the cathode 32. On the other hand, for an accelerating voltage applying period, as the cathode 32 is held at the first potential Vf1, luminance is not degraded.  Further, even if a potential of the cathode 32 is varied, the control of a device is not made complex, and the increase in the required number of parts is suppressed to less numbers.

IPC: G11B5/105
Filed: 1987-08-12
Abstract: PURPOSE:To easily prevent resin leakage and to reduce the costs of materials and labor by attracting and fixing plastic balls to the inside of the through-hole parts of a shielding case to prevent the resin leakage from the through-holes prior to packing of a resin therein. CONSTITUTION:A suction means 7 consisting of a suction part 7A and a suction pipe 7B is attached to the aperture of a hole 3 for mounting and audio head as a prepn. stage prior to packing of the resin. The suction means 7 is similarly mounted on the aperture on the outside of a pedestal mounting hole 4 and a hole 5 for preventing rotation. One ball is attracted in the aperture on the inner side of each through-hole when many balls 8 which are made of plastic soluble easily in an org. solvent and have a diameter slightly larger than the inside diameter of the through-hole are charged from the aperture 2. The remaining balls which are not attracted in the respective through-holes are then discharged to the outside by turning the shielding case 1 upside down. The org. solvent is thereafter sprayed on the attracted balls. The molten plastic 9 is attracted between the balls 8 and the aperture on the inner side of the through- holes, by which the balls 8 are tightly fitted and fixed into the aperture. The respective attraction means 7 are then removed. The resin leakage is thereby easily prevented and the cost is reduced.

Title: Ground circuit
Inventor: YAMAMOTO HIDEKI
IPC: H04B3/44
Filed: 1991-08-13
Abstract: PURPOSE:To prevent the generation of a pulse voltage giving adverse effect onto the system by limiting a surge voltage caused between a feeding ground and a station office ground due to lightning or the like to a voltage lower than the usual operating voltage. CONSTITUTION:When a ground voltage Vg between a feeding ground S.E and a station office ground ST.E gets tentatively higher than a Zener voltage Vz of a constant voltage diode D1 or D2, a surge voltage is applied to a gate of a thyristor Th via a capacitor C, which is turned on. In this case, the ground voltage Vg is limited to a voltage nearly equal to the Zener voltage Vz. However, when a surge current is lost, since the ground voltage Vg is lower than the Zener voltage Vz, a gate current of the thyristor Th is zero and the thyristor Th is turned off. In this case, a series circuit Dn comprising plural diodes inserted between the gate and a cathode of the thyristor Th limits a voltage caused across a resistor R2 by the flowing surge current.
