摘要： An electromagnetic, reflective type, active proximity sensor includes a transmitter, the transmitter including a voltage controlled oscillator circuit (78, 84), a transmitter circular waveguide (80) and a transmitter polarization circuit (70). The voltage controlled oscillator circuit (78, 84) generates an output signal which is modulated such that the frequency of the output signal varies over time between a range of frequencies. The frequency varying, output signal is provided to the transmitter circular waveguide (80) and propagated to the transmitter polarization circuit (70) where it is circularly polarized in a first circular direction. The circularly polarized, frequency varying, output signal is radiated by the transmitter to the target (50), where it strikes the target (50) and reflects back toward the sensor to form return signals. The return signals, upon being reflected, rotate in a second circular direction opposite to the first circular direction. The return signals also respectively exhibit one of the frequencies corresponding to the range of frequencies associated with the circularly polarized, frequency varying, output signal. The active proximity sensor also includes a receiver, the receiver including a receiver circular waveguide (82), a receiver polarization circuit (72) and a detector (32). The receiver circular waveguide (82) receives the return signals reflected from the target (50) and the receiver polarization circuit (72) circularly de-polarizes the return signals. Next, the detector (32) receives and averages the return signals and generates an output signal which corresponds to the return signals. The active proximity sensor also includes an analog processor/driver circuit (6) for processing the output signal provided by the detector (32).

摘要： An instrument dial, for example for use on the instrument panel of a motor vehicle, has a support structure (12, 112) and a printed face panel (22, 122). The printed face panel is formed from thermoformable sheet material which is provided with detent portions (34, 132) around its edge so that it can be clipped on to the support structure.

摘要： The object of the present invention is to provide a display apparatus for a vehicle in which luminance of the display pattern of letters, graduations, a pointer, and the like are increased without unevenness in the luminance but also the distance between a front face of a pointer plate and a rear face of the movement of the display apparatus is shortened. A circular pointer plate with a transmitting slit is disposed on front a portion of the display apparatus. An outer periphery of the pointer plate is toothed and is engaged with a driving gear fixed to a driving shaft of the movement to be directly driven by the movement. A dial is disposed on a back face of the pointer plate. A portion where the dial overlaps the pointer plate, and other portion for graduations and the like which surrounds the portion are formed as light transmitting portion, but, other portions are formed as light intercepting portion. Behind the pointer plate is installed a discharge lamp with a reflector.
