    • An automatic telephone answering device includes a diode bridge rectifier having its input terminals connected across a pair of telephone lines through a first switch, and its output terminals connected across a relay coil through a voltage controlled impedance, such as a Zener diode. A relatively high frequency, high voltage call signal is rectified by the bridge and breaks down the diode to energize the relay coil. This closes a relay switch to actuate a control circuit, whose outputs a) actuate a tape recorder unit to play back a prerecorded message to the caller, and b) simultaneously transfer the first switch to connect the tape recorder unit across the telephone lines through a line transformer. The breakdown voltage of the Zener diode is selected to be above the voltage level produced by sound (conversation) signals and busy tone signals, whereby the device presents a high impedance to such signals and is not actuated thereby.
    • 自动电话应答装置包括二极管桥式整流器,其二极管整流器的输入端通过第一开关连接在一对电话线上,其输出端通过诸如齐纳二极管之类的压控阻抗连接在继电器线圈上。 相对高频率的高电压呼叫信号由桥进行整流,分解二极管以使继电器线圈通电。 这将闭合一个继电器开关,以启动一个控制电路,其输出a)启动一个磁带录音机单元向主叫方播放预先录制的信息,以及b)同时传送第一个开关,通过一个电话线连接磁带录音机单元 线路变压器。 齐纳二极管的击穿电压被选择为高于由声音(对话)信号和忙音信号产生的电压电平,由此该装置对这种信号呈现高阻抗,并且由此不致动。

    • A light-transmitting film that has a predetermined polarization split function, in addition to a light-collecting function is provided. The index of refraction nx in a prism extension direction and the index of refraction in a prism alignment direction differ from each other. By generating a difference in the indices of refraction in the prism extension direction and the prism alignment direction orthogonal thereto, for the light incident on the light-transmitting film, the polarization component Lx oscillating in the prism extension direction and the polarization component Ly oscillating in the prism alignment direction can have different transmission characteristics. For example, by setting the index of refraction in the prism extension direction greater than the index of refraction in the prism alignment direction (nx>ny), among the light incident on the light-transmitting film, the amount of return light of the polarization component Lx oscillating in the prism extension direction is greater than that of the polarization component Ly oscillating in the prism alignment direction. In this way, not only a light-collecting function, but also a predetermined polarization split function is obtained.
    • 提供了除了聚光功能之外还具有预定的偏振分割功能的透光膜。 棱镜延伸方向上的折射率nx和棱镜取向方向上的折射率彼此不同。 通过产生棱镜延伸方向和与其正交的棱镜取向方向的折射率差,对于入射到透光膜上的光,偏振分量Lx在棱镜延伸方向上振荡,偏振分量Ly在 棱镜取向方向可以具有不同的透射特性。 例如,通过将棱镜延伸方向的折射率设定为大于棱镜取向方向(nx> ny)的折射率,入射到透光膜的光中,偏振光的返回光量 在棱镜延伸方向上振荡的分量Lx大于在棱镜排列方向上振荡的偏振分量Ly的分量Lx。 以这种方式,不仅获得了聚光功能,而且获得了预定的偏振分离功能。
