Title: Filamental cathode vibration preventing circuit
Inventor: TANIGUCHI HIROSHIGE
IPC: H01J31/12
Filed: 1989-12-25
Abstract: PURPOSE:To form a uniform picture display element without brightness change attended with vibration of a filamental cathode by using a filamental cathode vibration preventing circuit able to change a heating current of the filamental cathode timewise to always change a natural frequency of the filamental cathode. CONSTITUTION:With a switch 3 thrown to the position B, since the relation of levels between a boosting power supply 5 and an emission power supply 6 is expressed as V0>V1, a reverse current preventing diode 2 prevents a current flowing from the boosting power supply 5 to the emission power supply 6 and the level of a filamental cathode 1 is fixed to a level of the emission power supply 6 and electrons are emitted uniformly from the entire parts of the line cathode 1 similarly in the case of a conventional circuit. Since the heating current of the filamental cathode 1 is changed timewise in this way, the natural frequency is always changed and when the line cathode is driven by a signal of 60Hz, since the coincidence with frequencies being an integral multiple of 60Hz takes place at a short time, the vibration of the filamental cathode due to the resonance is suppressed small.

Title: Barrier rib forming method for plasma display panel
Inventor: ASAHI KOICHI
IPC: H01J9/02
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To form some desired barrier rib without causing any mold collapse in a barrier rib forming layer by employing such a burning condition as (M deg.C-20 deg.C) <= burning peak temperature <= (M deg.C+10 deg.C) provided that the softening point of the organic component of a barrier rib forming layer is M deg.C. SOLUTION: After applying glass paste on a glass substrate 1 on which an electrode 2 is formed, drying it so as to form a barrier rib forming layer 3. Next, a mask layer 4, a line pattern mask 5 and a mask 6 for sand blast are obtained and after aging, any unnecessary part of a forming layer 3 is cut off via a mask 6. In a temperature range from -20 deg.C to +10 deg.C around a softening point of the organic component of the forming layer 3, almost no mold collapse on account of burning is found, so as to obtain satisfactory configuration.  In addition, with regard to scattering rate of the barrier rib material, if its temperature drops by 10 deg.C beyond the softening point of the organic component of a forming layer 3, the rate becomes 1.5 times, if it drops by 20 deg.C, the rate becomes 2 times and if it drops by 30 deg.C, the rate becomes 3 times or more, resulting in an extreme increase in the scattering rate of the barrier rib.
