Abstract: PURPOSE:To realize a fast element by using a substrate which is doped with impurity forming a deep level, by thermally treating the substrate and by injecting oxygen selectively to a substrate between elements. CONSTITUTION:A semi-insulating GaAs substrate 1 which is doped with Cr is used. SiO2 is deposited on the GaAs substrate by CVD method to form a protective film. After heat treatment is performed to acquire a specified Cr concentration distribution, the protective film formed on the GaAs substrate 1 is removed. After a channel region 34 is formed on a surface of the GaAs substrate 1 and a gate electrode 35 is formed, a source diffusion layer 36a and a drain diffusion layer 36b are formed. Then, a source electrode 37 and a drain electrode 38 are formed to form FETs 32a, 32b. Oxygen ion implantation is selectively carried out to the GaAs substrate 1 between elements to form an oxygen injected region 33 which functions as an insulating region. Thereby, it is possible to prevent development of mutual interference between two elements, which is called side gate effect, almost entirely without obstructing high integration and to realize a fast element.

Abstract: PURPOSE:To eliminate an additional memory and also to obtain a liquid crystal display device with high reliability by setting a liquid crystal impressed voltage at a time other than a display expansion period in the vicinity to zero. CONSTITUTION:In order to expand periods between the 120-th and the 239-th of a video signal by utilizing a display expanding function, a scanning electrode 6-1 is brought into the selecting state as shown in (6-1)' for 1H of the period 120 by a control section 12 at first and other scanning electrodes 6-2-6-120 are brought into the non-selection state. A signal electrode selection signal or a signal electrode non-selection signal is impressed in response to the content of the video signal to signal electrodes 7-1-7-M. A voltage applied to the scanning electrodes 6-1-6-120 and the signal electrodes 7-1-7-M is made respectively equal so as to zero nearly the liquid crystal voltage at a period other than periods 120-239. Since the voltage impressed to the liquid crystal is nearly zero at a time other than the expanded period, crosstalk is not increased and the contrast corresponding to 120 divisions is attained.

Title: Image processing unit
Inventor: UENO KUNIKAZU
IPC: H04N1/40
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a multi-gradation image with higher image quality without losing a detailed edge or the like. SOLUTION: The processing unit stores respectively area pattern filters (a)-(h) shown in figure, and variances σ11-σ19 are calculated with respect to each area pattern based on a received image. Then a maximum variance is obtained among the variances σ11-σ19, a density mean value is calculated by using pixels in existence in parts other than an area pattern corresponding to the area for the maximum variance, that is, in an area B (not hatched part, an area not being a calculation object of a variance) shown in figure, and the result is outputted as a multilevel conversion value. This is because a low frequency edge with a gentle gray level change is more accurately multiplexed by eliminating an error cause and calculating pixels in a wider area.
