    • A radar apparatus includes: a modulation signal generating circuit that generates a modulation signal; a carrier wave generating circuit that generates a carrier wave; a modulation circuit that outputs a high frequency signal generated by modulating the carrier wave using the modulation signal that has been inputted; a modulation signal extracting circuit that extracts the modulation signal from the high frequency signal that has been inputted; and a detection signal generating circuit that generates a detection signal, which can be used to measure a distance to a measured object, based on the modulation signal extracted by the modulation signal extracting circuit from a component, out of the high frequency signal that has been transmitted via a transmission antenna, the component having been reflected by the measured object and received by a reception antenna. The modulation signal generating circuit includes a sine wave signal generating circuit that generates a sine wave signal and a pulse signal generating circuit that generates a modulation signal by converting the generated sine wave signal to a pulse signal using a step recovery diode.

    • A display apparatus comprises transparent display elements arranged on a transparent substrate, a display panel DP whose display image can be observed from either side, a pair of liquid crystal shutter means 2as and 2bs disposed in such a manner as to sandwich the display panel DP, display control means 13 and 15 for displaying, on the display panel, a mirror image of an image to be displayed in every other frame, and liquid crystal shutter control means 14 for opening and closing the pair of liquid crystal shutter means in synchronism with the operation of the display control means such that they do not open simultaneously in each frame scan. The pair of liquid crystal shutter means are opened and closed such that the mirror image can be observed as a regular image on one side of the display panel DP. Image information displayed on the display panel can be viewed simultaneously from both the front surface and the back surface of the display panel.
    • 显示装置包括布置在透明基板上的透明显示元件,可从任一侧观察其显示图像的显示面板DP,以及将显示面板夹在一起的一对液晶快门装置2和2 bs DP,显示控制装置13和15,用于在显示面板上显示要在每隔一帧显示的图像的镜像;以及液晶快门控制装置14,用于同步地打开和关闭一对液晶快门装置 随着显示控制装置的操作使得它们在每帧扫描中不同时打开。 一对液晶快门装置被打开和关闭,使得镜像可以作为显示面板DP的一侧上的常规图像被观察。 可以从显示面板的前表面和后表面同时观看显示面板上显示的图像信息。
