Abstract: PURPOSE:To provide the display device for wide-angle-of-field videos which obscures the joints of the videos displayed by dividing the wide-angle-of-field videos displayed on the inside surface of a dome to a plurality, is not affected by the shadows of the equipment materials in the dome and reflected light and has high economy. CONSTITUTION:A video display surface 19 on the inside surface of the dome is constituted by building up many optical fiber screens 15. The respective optical fiber screens are constituted by connecting video display surfaces 17 and light receiving surfaces 16 facing the display surfaces of liquid crystal displays 14 by bundles 18 of many optical fiber cables. Image information formed by dividing the videos 20 displayed on the wide-angle-of-field video display surface 19 is synchronously inputted to the respective liquid crystal displays 14.

Abstract: PURPOSE:To reduce memory capacity and transfer time required for data transfer by dividing plural processors each of which is provided with a local memory and a communication memory into groups and connecting the communication memories to corresponding data transfer controlling devices. CONSTITUTION:A communication memory CMij (i=1-3, j=1-n) and a local memory LMij are connected to each of N processors Pij, which are divided into three groups. The memories CMij in each group are connected to a data transfer controlling device DTCi having a broadcasting function and these devices DTC1-DTC3 are coupled like a ring to constitute a multiprocessor system. Data are exchange between the processors in each group through the DTC and data exchange between neighboring groups is also attained by a communication memory CMio. If the processing speed of these groups are divided into e.g. high, middle and low speeds, the whole system will have efficient constitution.

Abstract: PURPOSE:To obtain the video display device which can obtain a visual distance of a field of view of a real machine and a visual distance of a field of view being equal to a real distance to an object by a space docking simulator, in a simulator of an aircraft, etc. CONSTITUTION:In the upper part of a half mirror 1 for intersecting at 45 deg. with an optical axis of a concave mirror M, a CRT 2 is provided so that its display surface is reflected by the half mirror 1, and a virtual image 5 can be generated by the concave mirror M, and the CRT 2 can be displaced in its axial direction, by which a position in which the virtual image 5 is generated is formed between infinity and a point of a certain distance being nearer than it, and by setting the spherical center O of the concave mirror M as a visual point, the virtual image 5 is looked at.

Abstract: PURPOSE:To readily select the object to be corrected without requiring special knowledge by dividing the object into elements at its display and taking the element as an object when the result discriminating the right or wrong of the selection is correct. CONSTITUTION:When an operator selects the menu BR, for example, the video display is changed. As the display includes a part to be corrected, the selected operation is judged to be correctly performed. An object should be branched into OL and OR and the object OR is designed to include objects ORR and ORL. In this case, when the operator selects the menu BR again, the object ORR is selected but a part to be corrected (object ORL) is not included so that the selected operation is judged to be incorrectly performed. In this case, by selecting the R one-rank higher than the menus BR and BL, the upper object OR including the object ORR is displayed again on the video display device. When the menu BL is selected, the object ORL is properly selected.

Abstract: PURPOSE:To obtain an stereoscopic image easily by combining a display panel with a polarizing filter and a display panel without a polarizing filter. CONSTITUTION:A first display panel 9 is overlapped with a second display panel 10 of the structure formed by removing a polarizing filter from the first display panel 9. The light from the first display panel 9 is controlled in the direction of polarization by the second display panel 10. When the light subjected to this control is looked at through one-way polarizing spectacles, the light is visible at one part and unvisible at the other part. If spectacles with the left eye part and the right eye part having different polarizing directions is used, the light is divided into a part visible only by the right eye and a part visible only the left eye. Two images can be thereby displayed simultaneously by forming the image for the right eye and the image for the left eye appropriately so as to enable the formation of a stereoscopic image.

Abstract: PURPOSE:To eliminate overhead loss time and to quickly and easily adjust a timing for interruption by supplying a clock of a clock signal generator as a synchronizing interruption signal through a delay circuit to each computer. CONSTITUTION:A master clockboard 20 is set in a computer to become a master of composite computers, while delay circuit boards 211-21n are set in each of slave computers. A period of the master clock is decided by the master computer and also the master computer works on activation of this clock. While the delay circuits 121-12n set in each slave computer are set by the computer of the optimum delay period needed by the computer.
