摘要:
An image data coding system, wherein an image data in a bit map form is divided into first and second groups, pixels in each group of which are distributed over the whole area of the image data in the bit map form. First and second coders respectively code the first and second groups of image data into first and second groups of coded image data. The first and second groups of image data in the original image data are respectively input into first and second memories, respectively. Blocks of the first group of image data are supplied to the first coder at first times, respectively, and blocks of the second group of image data are supplied to the second coder at second times, respectively. Boundaries of the blocks in the first group of image data are located in different positions from boundaries of the blocks in the second group of image data, and the first times are different from the second times. In the receiver side, first and second decoders respectively decode the above first and second groups of coded image data into first and second groups of decoded image data. By composing the first and second groups of decoded image data, the original image data in the bit map form is restored.

There is provided a seal structure which surely maintains sealing performance of a pressure vessel including a bottomed tubular vessel body with an opening end and a lid closing the opening end. In this seal structure of the pressure vessel, annular grooves 11a, 11b and ridges 21a, 21b fitted to each other are formed on both of the inner and outer sides at the joining faces of opening end 11 of the vessel body 10 and the lid 20, and an annular vent hole 30 is formed between the inner ridge 21a and the outer ridge 21b. An air supply hole 31 for supplying an inert gas to the vent hole 30 is formed in the lid 20. The joining faces on the inside of the inner groove 11a and inner ridge 21a are in metal-to-metal contact. Furthermore, gaskets 51a, 51b are held between the ridges 21a, 21b and the grooves 11a, 11b.

摘要:
A method and apparatus for converting between different video formats, which provide smooth video motion by eliminating unnatural effects which could be introduced in the process of video format conversion. A frame interpolator produces interpolated frames from a first video signal given in a first video format by using motion vectors of the first video signal. From the interpolated frames, a video signal generator produces a second video signal in a second video format that is incompatible with the first video format.

A liquid crystal light valve includes a semiconductor substrate having a region for a plurality of switching elements formed in a matrix form. A first metal layer is formed on the surface of the semiconductor substrate through an insulating layer and divided into a plurality of parts by first slits. A second metal layer is formed on the first metal layer through another insulating layer and divided into a plurality of parts by second slits. A third metal layer is formed on the second metal layer through still another insulating layer and divided into a plurality of parts by third slits. An opposite substrate has an opposite electrode on a surface thereof, disposed so as to be opposite to said third metal layer through an interval on the opposite electrode side. Liquid crystal fills the interval between said opposite electrode and the third metal layer.
