摘要： PROBLEM TO BE SOLVED: To provide a method for producing a glass particulate deposit whereby the temperature of a raw material gas inside a feeder line is precisely controlled and stable operation becomes possible over a long period of time, and an apparatus for the same.
SOLUTION: In the method for producing the glass particulate deposit, a plurality of temperature-measuring means are installed at several points in a longitudinal direction of the feeder line of the raw material gas to measure temperature. Here, the feeder line is equipped with a heating and heat-retaining means. When the temperature at either of the measuring points drops to the minimum temperature within the heat-retention tolerance, a heating and heat-retaining power of the heating and heat-retaining means is increased. When the temperature reaches the maximum temperature within the heat-retention tolerance, the heating and heat-retaining power is decreased, so that the temperature of the raw material gas inside the feeder line is precisely controlled. The apparatus for producing the glass particulate deposit is also provided.

摘要： PROBLEM TO BE SOLVED: To provide a method of making a reflection film, avoiding damage due to laser irradiation, and collectively performing treatment for a number of optical parts having a coating film. SOLUTION: An optical substrate is prepared in a step S101 of a process flow 100. In a step S102, an optical coating film 14 is formed at the end face of an optical substrate such as a semiconductor laser. When the film thickness varies in a range from -5% to +5%, the wavelength at which the reflectance of a low reflection film is minimum varies from -28 nm to +28 nm. The coating film is put in a thermostatic chamber whose humidity and temperature can be controlled in a step S103. In a step S104, the semiconductor laser 10 is held in the thermostatic chamber to vary the reflectance of the optical coating film 14. After this, the semiconductor laser 12 is taken out from the thermostatic chamber. The humidity of the thermostatic chamber is 90% (relative humidity), for example, and the temperature is 75°C, for example. COPYRIGHT: (C)2009,JPO&INPIT
