Abstract: A seismic isolator wherein vibrating units 5 arranged in a multiplex manner are formed of suspension members 53 constituting tensile force bearing members, and frames 51 and bases 52 to which both end portions of the suspension members are joined, adjacent vibrating units 5, 5 being joined together by diagonal members 6 of wire rods constituting compressive force bearing members, whereby the area occupied by the seismic isolator decreases.

Abstract: A method of and a system of camera control are shown, in which a monitoring area view 2 is displayed on a monitor screen 1a. An installation position A of a camera unit 5 is input as origin A on the monitoring area view 2 with a point input unit 4. Further, a point B indicative of the home position direction of the camera unit 5 is input from the point input unit 4. A line connecting the pick-up position A of the camera unit and home position direction B thereof are set to be a virtual line C (0.degree.); and a monitoring point X is input on the monitoring area view with the point input unit 4 to obtain a monitoring point angle .theta.a which is defined by the designated monitoring point X, the origin A and the virtual line C. The camera unit 5 is caused to undergo revolution by the monitoring point angle .theta.a.

Abstract: It is sought to display a pluralities of full motion image sequences together with personal computer texts, graphics, etc. on a personal computer display. NTSC signal converters 100 (10A, 10B, . . .) each provided for each video input channel each send out color digital brightness signals of a contracted image size, obtained through conversion of a video input signal. These signals are written in and read out from R, G and B color signal memories 20 under control of a command from a write/read controller 23. The read-out color digital brightness signals are converted in a digital-to-analog converter 30 into analog signals. An overlay controller 31 overleys these analog signals over R, G and B analog inputs from a personal computer under control of a display position determining signal supplied from a CPU via a personal computer bus 41, thus producing R, G and B analog outputs which are displayed as image sequence on the same personal computer display.

Abstract: A control method and a control system are disclosed, which allow high speed introduction of an intended foreground subject in a camera picture, and in which by designating a given position of a picture displayed on the screen of a CRT with an external input the position can be moved to the screen center or to a predetermined position, while enlargement and contraction are made automatically. The operation is thus simple, less movement of eyesight is required, no operation error is committed, and a large number of cameras can be connected with a small-size and easily operable system.
