Title: Preparation of porous glass parent material for optical fiber
Inventor: KAMIYA KAZUO
IPC: C03B37/014
Filed: 1984-04-16
Abstract: PURPOSE:To prepare the titled porous glass parent material having superior quality by feeding gaseous starting materials for the glass to a flame hydrolysis zone with a fixed feeding pressure through a buffer tank. CONSTITUTION:Starting materials for glass such as Si component and doping material, etc. are contained individually in separated closed vessels held at specified temps. and are taken out with specified flow rates by allowing them to be carried by an inert carrier gas introduced from each bubbler provided to each vessel. The gas is then introduced into a buffer tank having 100-10,000 times inside volume basing on the sum of the feeding flow rate per sec of the carrier gases contg. each component of the starting materials. The pressure of the buffer tank is adjusted to a fixed feed pressure, and the gas is then fed to a burner in a flame hydrolysis reaction zone to form the porous glass parent material. By this method, laminar fluctuation of refractive index of the parent material caused by the flare of flame is prevented.

Title: Method for recovering metal from metal silicide material and high-purity tungsten recovered by this method
Inventor: YANO TOSHIHIRO
IPC: C22B34/36
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for easily and inexpensively recover metal more particularly from used metal silicide materials. SOLUTION: The metal silicide materials added with SiO2 are roasted, by which a chemical reaction is induced between the silicon included in the silicide materials and SiO2 and highly volatile gaseous SiO is formed and the desiliconization reaction of the silicide materials is progressed. Further, the gaseous SiO is dissolved (for example, by an electron beam), by which the evaporation and removal of the silicon of the high vapor pressure component from the roasted material, i.e., desiliconization reaction, are progressed. This method is successfully usable for recovery of the metals from the high melting metal silicide, such as tungsten silicide. molybdenum silicide and tantalum silicide. The more preferable roasting conditions are at >=1000 deg.C and at an in-furnace pressure of <=10Pa.

IPC: G11B11/10
Filed: 1986-04-01
Abstract: PURPOSE:To improve recording and reproducing characteristics, long-period reliability and quality by in a multi-layered structure including a reflection film forming the reflection film of a metal or metalloid such as titanium having low heat conductivity. CONSTITUTION:The 1st transparent dielectric film 2 consisting of transparent aluminum nitride, a thin rare earth transition metallic alloy film 3, the 2nd transparent dielectric film 4 and the reflection film 5 consisting of titanium are successively laminated and formed on a transparent substrate 1 and are made into multi-layered structure. The heat conductivity of the film 5 is made lower by using the titanium as compared to the case of using metal such as Al, Cu or Ag, by which the escape of the heat is decreased at the time of making recording by irradiating a laser to the recording medium and the recording and reproducing characteristics is improved. The long-period stability is made higher by the thermal stability and since the reflectivity is high as well, the reflection film having the substantial quantity of reflected light is obtd. to the regenerating system. The recording and reproducing characteristics are improved and the long-period reliability and quality are improved by forming the reflection film of the metal or metalloid having the low heat conductivity in the above-mentioned manner.

Filed: 1978-06-28
Abstract: PURPOSE: To hold the operation signals before the power supply loss for a long period of time to omit the backup battery and thus to facilitate the maintenance by providing the memory to memorize the process operation amount and the nonvolatile memory to hold the operation amount at the time of the power supply loss.  
     CONSTITUTION: In case the control voltage of power unit 6 is lost, the loss is detected via monitor relay 7. And relay 9 is switched off and electromagnetic value 11 is opened with control valve 12 locked. Nonvolatile memory 24 holds the value of the power voltage before loss. When the voltage is recovered, relay 7 and 9 are switched on. And relay 26 is switched on by the control of relase control circuit 21 of the digital controller to set the contents of memory 24 to analog memory 5. The tie-back signal is compared 22 with the contents of memory 24 through analog input circuit 27-2. And if an coincidence is obtained, relay 25 is switched on via circuit 21 with valve 11 turned on to release the lock of valve 12. As a result, the before-loss state is secured even after the power supply loss for a long time, thus continuing the operation.
