摘要： In a multi-location television conference system that connects five locations A, B, C, D, and E, when speeches take place at the four locations A, B, C, and D at the same time, at a listening location E, images of all the speaking locations A, B, C, and D are displayed on one screen with four divided screen areas. On the other hand, at the speaking location A, images of the speaking locations B, c, and D and an image of the former speaking location E are displayed on one screen with four divided screen areas. In addition, when images of speaking locations are displayed, locations names thereof are also displayed. Thus, a television conference held at a plurality of locations at a time can be smoothly managed as with a real conventional conference.

摘要： A multi-site video conference control system comprising a number of video conference terminals respectively situated at a number of sites and a video conference control unit for controlling a video conference. A communication line interface provided at each terminal makes a single calling with respect to the video conference control unit. A connection data section, which is provided at each terminal, manages connection data for other terminals to be connected and transmits the connection data to the video conference control unit. A control calling section, which is provided at the video conference control unit, calls the terminal corresponding to the connection data to be transmitted from the connection data section, based on the single calling. A connection controller, which is provided at the video conference control unit, connects the calling terminal, whose communication line interface made the single calling, and the other terminals called by the control calling section, with communication lines.

摘要： In a multipoint video conferencing system wherein two images of a selected primary conference room and a selected secondary conference room are distributed to each CT, an unnaturalness, such that an exchange of right and left images occurs while a conversation is held between two conference rooms, arises. The unnaturalness is avoided by constructing the conference room terminal so that images displayed on two screen are exchanged when both of the primary and the secondary conference rooms are altered.

摘要： This invention discloses an electrically driven elevation bed apparatus which moves up and down while keeping its horizontal posture, in order to make effective use of indoor space. The elevation bed of this invention includes improved driving systems and safety devices for the driving systems. The driving systems includes a driving device including a spring to store biasing force on a supporting shaft thereof for the ascending of the bed frame. Also included is the use of steel belts as cord bodies to hand the bed frame to make the driving device compact and to eliminate troubles encountered with wireropes. The third aspect of the present invention also relates to an improvement of the driving systems. This aspect enables the bed frame to be positioned in inclined postures by introducing clutch means in the driving device to raise one side of the bed only. To the elevation bed, various safety devices are provided for movement of the furniture. They are a detecting device to detect the loss of tension or breakage of cord bodies, a disengagement preventing device to secure the engagement of the bed frame and guide rails, a protecting device using a guard net to prevent the user from falling from the bed and cushioning device to improve the starting motion of the bed frame by eliminating shock and by enabling the driving device to be more effective and safer in its operation. The present invention includes systems which can be combined and the various safety devices are available to be adopted correspondingly and combined freely.
