Abstract: PURPOSE:To improve recording sensitivity and repetitive characteristics for writing and erasing of the medium by controlling sputtering conditions to vary the amts. of carbon, hydrogen and oxygen in dielectric layers so as to obtain the optimum state of thermal conductivity, residual stress and heat resistance of the dielectric layers. CONSTITUTION:Such a material showing intermediate properties between inorg. materials and org. materials concerning to thermal conductivity and heat resistance is used for the dielectric protective layers adjacent to a recording layer. For example, Si-N films or SiC films containing hydrogen or Si-O films or Zn-S films containing carbon and hydrogen are used. These films are formed by sputtering or vapor deposition, which is a simple method with excellent productivity and can be preferably controlled. Namely, the dielectric films containing carbon and/or hydrogen are produced by reactive sputting or reactive vapor deposition using reactive gas such as hydrocarbon, hydrogen, ammonia, oxygen, etc. The obtd. dielectric films have excellent low thermal conductivity and heat resistance showing both advantages of org. materials and inorg. materials, and moreover, residual stress in the films can be easily reduced.

Title: Distance-measuring apparatus
Inventor: NONAKA OSAMU
IPC: G01C3/06
Filed: 1993-11-24
Abstract: PURPOSE:To measure the distance highly accurately without being influenced by reflectance of a to-be-photographed object, by detecting reflecting light of a measuring luminous flux from the object and outputting two photoelectric conversion signals depending on the incident position. CONSTITUTION:A CPU 1 drives an infrared light-emitting diode 3. The generated light is condensed by a lens 4 to be a distance measuring light. A reflecting signal light from a to-be-photographed object is collected by the lens and made incident on a semiconductor position-detecting element (PSD). The PSD converts the reflecting signal light into a current proportional to intensity of the light and further divides into two current signals I1, I2 by a ratio depending on an incident position X. The currents I1, I2 are amplified by preamplifiers 7, 8, and outputs from the preamplifiers 7, 8 are both input to a ratio-operating circuit 9 and a sum-operating circuit 10. An electrically reloadable memory E<2>PROM 11 stores error components of these circuits beforehand. The CPU 1 calculates a distance to the object based on the results of the circuits 9, 10 and memory 11.
