    • A conference video display system is provided for allowing attendees at the conference to switch to the video images of their respective personal computers at will, and eliminating the need for determining the correlation between the personal computers and channels of a switching unit, to provide facilitated and appropriate video switching. The system has a switching unit for receiving a plurality of video signals and selectively outputting the received video signals, and a plurality of connection cables for connecting the switching unit and a plurality of personal computers. Each of the connection cables has a selection request switch near the personal computer connected thereto to make the switching unit select the video signal from the connected personal computer as an output video signal thereof.
    • 提供会议视频显示系统,用于允许会议中的与会者随意切换其各自的个人计算机的视频图像,并且消除了确定个人计算机和交换单元的信道之间的相关性的需要,以提供便利和 适当的视频切换。该系统具有用于接收多个视频信号并选择性地输出所接收的视频信号的切换单元和用于连接切换单元和多个个人计算机的多个连接电缆。 每个连接电缆在与其连接的个人计算机附近具有选择请求开关,以使切换单元从连接的个人计算机中选择视频信号作为其输出视频信号。

    • A vehicular slope apparatus (1) includes a first slope section (10) that is rotatably connected to a body of a vehicle, and a second slope section (20) that is slidably connected to an extension side of the first slope section (10), the first slope section (10) including assistance mechanism (50) that applies an assistance force (Mf) in a direction in which the first slope section (10) rotates upwardly and, the assistance force (Mf) being larger than a downward moment that occurs at a center of gravity (M1) of the entire apparatus (1) when the entire apparatus (1) is horizontalized in a state in which the second slope section (20) is received within the first slope section (10), and is smaller than a downward moment that occurs at a center of gravity (M2) of the entire apparatus (1) when the second slope section (20) is extended from the first slope section (10) to a maximum extent, and the first slope section (10) rotating when the second slope section (20) has been extended to a predetermined extent so that an end of the slope apparatus comes in contact with the ground.
    • 车辆斜坡装置(1)包括可旋转地连接到车辆主体的第一倾斜部分(10)和可滑动地连接到第一斜坡部分(10)的延伸侧的第二倾斜部分(20) 所述第一斜坡部分(10)包括在所述第一倾斜部分(10)向上旋转的方向上施加辅助力(Mf)的辅助机构(50),所述辅助力(Mf)大于向下力矩 当整个装置(1)在第一斜坡部分(10)中接收第二斜坡部分(20)的状态下水平时,整个装置(1)的重心(M1)处的重心(M1)发生; 小于当第二斜坡部分(20)从第一斜坡部分(10)延伸到最大程度时在整个装置(1)的重心(M2)处发生的向下的力矩,并且第一斜面 当第二斜坡部分(20)已经延伸到预定位置时,部分(10)旋转 使得斜坡装置的一端与地面接触。
