摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing silica glass by which bubble-free silica glass is easily manufactured at high yield.
SOLUTION: In the method for manufacturing the silica glass, transparent silica glass is manufactured by mixing silica sol with silica powder having 1-10 μm particle diameter in a ratio of 1:2-2.3 by pts.wt., pouring the mixture into a forming die and gelating the mixture to form a silica formed body, drying the silica formed body and primarily firing the dried silica formed body at 1,000-1,400°C under the atmosphere to form a silica porous body and firing the silica porous body at a reduced pressure under an inert gas atmosphere in a vacuum pressurizing firing furnace.

摘要： PROBLEM TO BE SOLVED: To provide a plasma resistant member which resists sufficiently even when it is exposed to plasma and which is produced at a reduced cost, and to provide a method of producing the same. SOLUTION: The plasma-resistant member is characterized in that the surface area to be exposed to plasma under a corrosive gas atmosphere is formed by using a zirconia-based sintered compact in which 7 to 17 mol.% yttria is contained in a dispersed state. It is preferable that the center line average roughness (Ra) being one of properties of the surface area is 1.2 to 5.0 μm. The value of the center line average roughness (Ra) in such a range is easily obtained by etching the surface area with an etching solution containing hydrofluoric acid.

摘要： PURPOSE:To provide an operating system for electric vehicle which is preset at a constant speed by depressing a push button provided on a steering wheel in an operating unit and subsequently traveled at a constant speed through manipulation of the steering wheel wherein reliability and safety are enhanced by setting a command speed and an acceleration by means of a single steering unit thereby facilitating operability. CONSTITUTION:An operating board 10 installed in the cabin of an electric vehicle comprises an operation commander 12 equipped with a speed indicator 11. The operation commander 12 is connected with a controller 14 for operating a driver 15 and a powering command operating unit 16 delivering a traction power signal and a command speed signal. The operating unit 16 is provided with a steering wheel 17 being pushed back and forth to bring about a constant operating speed. A push button 19 is provided at one end of the steering wheel 17 such that the push button 19 is switched by pushing an auxiliary switch for setting the constant operational speed.
