Title: Video signal processor by multiprocessor
Inventor: AKAMATSU NAOKI
IPC: H04N5/262
Filed: 1993-01-22
Abstract: PURPOSE:To precisely execute a video signal processing when the number of picture elements in one horizontal period is within the number of the shift register constitution stages of a video signal processor by providing a means changing the phase of a synchronizing clock whose one processing unit time for an input-side shift register is decided. CONSTITUTION:The processor consists of the video input-side shift register of S(=N) stages 101, which is provided with a simultaneous write mechanism, the video output-side shift register of S-stages 104, which is provided with a simultaneous read mechanism, and a synchronizing clock delay circuit 120. The phase of the synchronizing clock for the input-side shift register 101 is delayed by a difference between the number of the stages S in the input/output- side shift registers 101 and 104 and the number of one processing unit constitution picture elements in a video signal. Thus, the head of the picture element constituting one processing unit when the input-side shift register 101 executes simultaneous writing is made coincident with the head of the picture element constituting one processing unit when the output-side shift register 104 executes simultaneous reading. Then, the picture elements constituting one processing unit are processed in the same processing time.

Light emitting display parts 20 having red, green and blue display parts 12, 13 and 14 exist on a second substrate 3 opposed to the FEC 5. Three-color filters (r, g and b) of the respective display parts are coated with light transmissive positive electrode conductors 15, and are coated with phosphors R, G and B whose luminescent colors are the same with the respective filters. The phosphor of the blue display part 14 is a ZnO:Zn phosphor abundantly containing a wave length component of about 400nm to 650nm, particularly, a blue component not more than 500nm. When it is combined with the blue filter (b), blue light is efficiently obtained. When the filter is driven by positive electrode voltage of 400V, since a brightness survival rate of the ZnO:Zn phosphor after continuous light emission of 1000 hours is 100%; and long service life and high reliability are obtained. The blue color filter (b) contains inorganic pigment and frit glass, and can endure a sealing process at about 500 deg.C in a manufacturing process of a fluorescent character display device.

Subsequently, the fused portion M is clamped between concave and convex surfaces 4 and 5 of respective heating members 6 and 7 and pressed therebetween to obtain a joining portion M. By this method of joining threads Y the fused portion is reduced, so that it is hardly recognizable when the threads are dyed. In addition, the fused portion has a high mechanical strength, so that it can be difficultly broken apart. Thus, it is possible to improve the operation control property in a high degree processing and also improve the quality of the product.

Abstract: PURPOSE:To narrow the element spaces while cutting down the number of processes by a method wherein a well contact region and source regions are formed in selfalignment within a well region. CONSTITUTION:Source regions 28 or a well contact region 26 are selectively formed by implanting ion in a well region 26 using the thickness difference of oxide films on the surface of the well region 26. Later, thermal nitride films 29 are formed by thermal nitrification only on the interface between an oxide film 22 and source regions 28 or the well contact region 26 also using the thickness difference of oxide films. Next, after removing the other oxide films 31, the residual regions out of the sour//ce regions 28 and another well contact region 33 are formed by diffusion process in selfalignment with previously formed regions below the thermal nitride films 29. Through these procedures, the matching allowance can be eliminated and manufacturing processes can be simplified.
