Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a structure of which can be hardly cut off the electric connection between an upper electrode and an upper electrode bus line by forming the upper electrode and the upper electrode bus line having the thinned connecting side on a protective insulating layer, and connecting the upper electrode to its thinned part, while covering the upper electrode bus line. SOLUTION: In a cross section equivalent to a single electron source of a thin-film type electron source, an opening part of a thin upper electrode bus line lower layer 15A approaches an electron-emitting part surrounded by a protective insulating layer 14 more than an opening part of an upper electrode bus line upper layer 15B. An upper electrode is formed of the upper electrode bus line upper layer 15B, the upper electrode bus line lower layer 15A, the protective insulating layer 14 and an insulating layer 12 of the electron emitting part surrounded by it. Since the upper electrode bus line lower layer 15A is thin, the upper electrode 13 is hardly disconnected in its step difference part, and no matter how steep a step difference of the upper electrode bus line upper layer 15B is, electrical contact with an upper electrode bus line is maintained. Therefore, the upper layer 15B may be thickened to any extent.

Title: Changing system for os interruption level
Inventor: SUGAMIYA HITOSHI
IPC: G06F9/46
Filed: 1990-10-26
Abstract: PURPOSE:To shorten the inhibiting time to the interruption applied from an input/output device and to improve the responsiveness by changing the interruption level of its own after saving the interruption information of an external input/output device so as to secure an interruption acceptable state. CONSTITUTION:In an interruption level changing system of an OS 1, the interruption levels occupied by the interruptions of higher priorities received from an external input/output device can be accepted when the interruption information and the execution registers are saved to the system stackers 17 and 18 and the level of the interruption state that is inhibited at the present interruption level is lowered. As a result, the interruption inhibiting state is extremely shortened during the interruption processing of the OS 1 and therefore an interruption waiting state is not easily produced for the external input/output device. Thus it is possible to prevent the destruction of the input data due to an interruption waiting state and to prevent the malfunction of the external input/output device due to the loss of the interruption information.

Abstract: PURPOSE:To shorten an expanding processing time as a whole by operating the compression-processing of a picture in which a dummy picture is added to an inpt picture, at the time of using a large capacity coded data storing means. CONSTITUTION:FIFO(First In First Out) 9-1 to 9-n as exclusive small capacity temporary data storage means are individually provided on respective compression-expanders 6-1 to 6-n, and the data are transferred sequentially from the FIFO in which the prescribed quantity of data is stored, to one coded data storage means 11.

At this time, the dummy picture is added on the expansion of an input picture to an image memory 5, and the compression- processing of the picture in which the dummy picture is impressed on the input picture is operated. Therefore, the data whose compressibility is satisfactory is a little deteriorated, and the coded data are frequency stored in the hard disk 11-2, so that the expanding time of the entire coded data can be shortened.

Title: Liquid crytal diplay element with thin film transistor
Inventor: SATO MAKOTO
IPC: G02F1/1333
Filed: 1992-10-26
Abstract: PURPOSE:To vary a voltage applied to liquid crystal on one pixel so as to prevent a reversing phenomenon of half-tones and to obtain a wide visual angle even with half-tones by providing an insulating film on a transparent substrate and varying the thickness of this insulating film on the transparent electrode. CONSTITUTION:The transparent electrode 3 has an area ratio 1:4 between an A area 3a which is covered with the insulating film 6 and a B area 3b which is not covered with the insulating film 6, so a voltage applied to the liquid crystal in the A area 3a is 75% of that in the B area 3b. Consequently, the voltage transmissivity characteristics (V-T characteristics) in the A area 3a become dull, and consequently the mean V-T characteristics of one pixel vary. Therefore, a reversing phenomenon of half-tones is caused almost at 24 deg. in the downward direction before, but the reversing phenomenon of half-tones is not caused up to about 45 deg. in the downward direction in this invention. Consequently, the tilt angle of the liquid crystal becomes large at the time of voltage application and the contrast in a slanting direction becomes high.
