Abstract: An oil-repellent coating layer 2 is disposed on both surfaces of a lens material 1 consisting of glass or a plastic. Furthermore, a minute particle layer 3 in which minute particles of a metal oxide or minute particles of a fluoride, or both, are dispersed is formed on the surface of the oil-repellent coating layer 2, and a resin layer 4 consisting of an organic compound is disposed on the surface of the minute particle layer 3. Since the adhesion between the resin layer 4 and the two-sided adhesive tape that is used when the lens is set in the lens edging machine is good, axial shifting tends not to occur during working.

Abstract: A transmission channel selection controller intermittently energizes transmission amplifiers indicated by transmission channel information, based on a modulation signal supplied from a modulation signal generator, to modulate an FM signal. The modulated FM signal is radiated as a beam from transmission antennas. When the beam is reflected as an echo beam by an object, the echo beam is received by reception antennas which supply a reception signal to reception amplifiers. A first mixer mixes the FM signal with the amplified reception signal, producing a modulated beat signal which is a beat signal representing the distance up to the object and modulated by the frequency of the modulation signal. A second mixer mixes the modulated beat signal with the modulation signal thereby demodulating the modulated beat signal into the beat signal.
