Filed: 1988-11-22
Abstract: PURPOSE:To vary the power of an optical lens itself continuously and to prevent an obtained image from being distorted by varying the refractive index in a liquid chamber, changing the optical path of light passing through the liquid chamber, and putting the optical lens in focus. CONSTITUTION:The refractive index of liquid put in the liquid chamber 22 is varied by using a 1st liquid supply device 23 and a 2nd liquid supply device 24. For example, when the refractive index of the liquid put in the chamber 22 is larger than '1' which is equal to the refractive index of air, transmitted light is propagated slower than in air, the geometric optical distance is larger than its apparent distance, and consequently an image formation lane 27 is put away from the optical lens 21. Thus, the refractive index of the liquid put in the liquid chamber 22 is varied to focus a subject S on the image formation surface 27, thus putting the lens in focus. Consequently, there is no mechanical moving part, the power of the lens itself is varied continuously, and the obtained image is never distorted.

Abstract: PURPOSE:To increase performance by using a carbon cluster thin film, in which impurities are doped, as a sensor element. CONSTITUTION:For example, when oxygen is detected, a gas sensor in which the resistance of a dope carbon cluster thin film 4 shows a range of 10<4>OMEGA.cm B to 10<-3>OMEGA.cm immediately after a thin film is formed in vacuum and room temperature is used. A current is flown through the dope carbon cluster thin film 4 from current terminals 33 and 34, and voltage is measured using voltage terminals 31 and 32 to measure the resistance of the dope carbon cluster thin film 4. When the thin film 4 is exposed to the atmosphere, oxygen in the air is adsorped on the thin film 4 and resistance varies largely, and increases to 10<7>OMEGA.cmB to 10<9>OMEGA.cm level in a few minutes.
