Title: Manufacture of wiring board
Inventor: KANEKO NORIHIKO
IPC: H05K3/10
Filed: 1991-12-25
Abstract: PURPOSE:To make it possible to use as many board materials and conductor wiring pattern materials as possible. CONSTITUTION:Photoresist layer 2 for a negative wiring pattern are formed on the top of an insulation board 1 and conductor powder or particles 3 are deposited in slots 4 between the photoresist layers 2 with high density. When the insulation board is adapted to pass through a high frequency electro-magnetic induction furnace, maintaining this state, the conductor powder or the particles 3 are heated and melted. Then, when they are cooled and cured, a conductor wiring pattern is formed in the slots 4 between the photoresist layers 2. In this case, any insulation board material will be acceptable only if they can be melted, cured and then fixed. More specifically, it is possible to use such materials as glass, ceramics, resin films or the like. It is also possible to adopt a single substance, such as copper, gold, silver, chrome, nickel and molybdenum or their alloy as for conductor wiring pattern materials.

Title: Phosphor material production thereof, phosphor film, and plasma display panel
Inventor: KADO HIROYUKI
IPC: H01J11/44
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain a phosphor film which has a high filling factor of phosphor particles and good reflection characteristics by using a phosphor material having a particle size distribution having at least two peaks. SOLUTION: This phosphor material has a particle size distribution having at least two peaks, one in the range of 1.5-5 μm and the other at 1.5 μm or lower. The particle size at one of the two peaks is at least twice that at the other, and the particle size concentration degree * defined by the formula: χ=100A/(A+ddmax -dmin ) is 50-100%. In the formula, A is the average particle size; dmin is the min. particle size; and dmax is the max. particle size. The particle size distribution having at lest two peaks causes small-size particles to be filled into among large-size particles and enables the filling factor to be improved, improving the reflectance in the film. As the phosphor material, BaMgAl10 O17 : Eu<2+> is used for a blue phosphor; Zn2 SiO4 : Mn<2+> or BaAl12 O19 : Mn<2+> , for a green phoshor; and YBO3 : Eu<3+> , for a red phosphor.

IPC: H04N3/23
Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To improve unevenness of luminance being a beat noise. SOLUTION: A clock signal generating means 50 generating a reference clock signal performing a digital processing is provided with respect to the deflection and picture distortion correcting means 16 which generates a correction signal correcting a defection and a picture distortion and a clock signal asynchronous to a synchronizing signal is supplied to the correcting means. Cyclic signals of a vertical synchronizing signal VS' and the like are supplied to the correcting means and the frequency of the clock signal is varied with these cyclic signals. In short, the frequency of the clock signal generated in a state asynchronous with a horizontal synchronizing signal is varied in a prescribed cycle.  As a result, the average level of unevenness of luminance is reduced by prolonging the repeatitive cycle of unevenness of luminance which are generated at the same horizontal position by the beat of the horizontal synchronizing signal and the clock signal. Moreover, the degradation of display quality of unevenness of luminance generated in the vicinities of four corners of the screen of a display device is improved by sharply reducing unevenness of luminance than in the conventional practice.
