    • An extremely durable, super-high speed shutter with speeds of 1/8000 second or faster advantageously increases the blade acceptance rate, reduces the cost, prevents abnormalities such as light leaking between the curtains and the like, contributes to the implementation of a super-high speed shutter with speeds exceeding 1/8000 of a second, corresponding to TTL multi-pattern light adjustment, and the like. The shutter includes a front curtain and a rear curtain each including a plurality of dividing blades; and at least one of the dividing blades among the front curtain and the rear curtain that is positioned on the photo lens side is formed from a black material having at least one uncoated surface.

    • A video telephone system which includes a master video telephone terminal (secretary terminal) connected to a communication network and slave video telephone terminals (executive terminals) connected to the master video telephone terminal in which the master video telephone terminal can transfer a call to the slave video telephone terminals. When a call comes into the secretary terminal from a remote terminal on the communication network, a line control section of the secretary terminal sets up a line. Video data and speech data received on the line are decoded by a video signal coding-decoding section and an aural signal coding-decoding section and the decoded signals are output through a display and a speech output device. Sound and images picked up by a microphone and a camera respectively are coded for transmission. Then, if a predetermined instruction of call transfer to an executive terminal is entered on an electronic tablet of the secretary terminal, a communication branch control section of the secretary terminal calls the executive terminal, sets up a line between the secretary and executive terminals on a local transmission network, and connects the line between the secretary terminal and the remote terminal.
    • 一种视频电话系统,包括连接到通信网络的主视频电话终端(秘书终端)和连接到主视频电话终端的从属视频电话终端(执行终端),其中主视频电话终端可以将呼叫转移到从属 视频电话终端。 当来自通信网络上的远程终端的秘书终端呼叫时,秘书终端的线路控制部分建立一条线路。 在线上接收的视频数据和语音数据由视频信号编码解码部分和听觉信号编码解码部分解码,解码信号通过显示器和语音输出装置输出。 由麦克风和相机分别拾取的声音和图像分别进行编码以进行传输。 然后,如果在秘书终端的电子平板电脑上输入了对执行终端的呼叫转移的预定指令,则秘书终端的通信分支控制部分呼叫执行终端,在秘书和执行终端之间建立一行 本地传输网络,并连接秘书终端和远程终端之间的线路。

    • An automatic welding apparatus comprising a workpiece fixture carried by a moving member for rotation about a horizontal axis extending in a back and forth direction, said moving member being provided on a carriage for sliding movement in a lateral direction, said carriage being provided for sliding movement in said back and forth direction, and a torch fixture carried by an arm for rotation about a vertical axis, said arm being provided for sliding movement in the vertical direction. In another embodiment, the workpiece fixture is provided only for rotation about a horizontal axis extending in the back and forth direction, and the torch fixture is carried by the arm for rotation about the vertical axis, which arm is provided at the end of a column for sliding movement in said lateral direction, which column is provided on a sliding member for sliding movement in the vertical direction, which sliding member is provided on a guide for sliding movement in said back and forth direction. The movement of these components is controlled in an electronic manner in accordance with a preset, i.e. predetermined data. The degree of freedom of the movement of the workpiece and torch is thus divided into both workpiece and torch fixtures and as a result welding a workpiece of complicated shape is possible in a better attitude of the torch and the workpiece.
