The present invention provides a charge neutralizer for accurately irradiating a soft X ray into a narrow gap after a glass substrate is lifted up.A soft X ray is introduced into a gap “d” from a soft X ray charge neutralizer 14, and the soft X ray is detected by a soft X ray optical axis monitor 16. Mounting position adjusting means 15 is adjusted by a detection output from said soft X ray optical axis monitor, and optical axis alignment is performed. Next, according to information from a database 19, a control unit 17 controls gap adjusting means 13, and charge neutralization is performed. Charge neutralization can also be performed by controlling the gap “d” by the gap adjusting means 13 while judging neutralizing conditions as to whether a charged potential measured by an electrometer 18 is within an allowable value by the control unit 17 or not.

摘要:
A nitrile group-containing highly saturated copolymer rubber which is a product obtained by hydrogenating the conjugated diene portion of an unsaturated nitrile-conjugated diene copolymer. The highly saturated copolymer rubber has an alkylthio group having 12 to 16 carbon atoms, which include at least three tertiary carbon atoms, and having a sulfur atom which is directly bound to at least one of the tertiary carbon atom, and the highly saturated copolymer rubber further has a Mooney viscosity of 15 to 200 and an iodine value not larger than 80. The highly saturated copolymer rubber is produced copolymerizing an unsaturated nitrile, a conjugated diene and an optional copolymerizable monomer by using as a molecular weight modifier an alkylthiol compound having 12 to 16 carbon atoms, which include at least three tertiary carbon atoms, and having a sulfur atom which is directly bound to at least one of the tertiary carbon atoms; and then, hydrogenating the thus-obtained copolymer. The highly saturated copolymer rubber exhibits a high-rate vulcanizability when vulcanized with a sulfur-containing vulcanizer.

A dynamic traffic control method is disclosed that controls traffic in a radio network system where a radio network controller causes plural radio base stations to change radio outputs. The method comprises a step of measuring a channel utilization rate of each of cells of the radio base stations every predetermined period, a step of predicting whether the rate of a first cell of the cells reaches an implementation level, at which radio output control over the first cell is required, in a next period based on a movement of the rate in the past if the channel utilization rate of the first cell is at a warning level, and a step of reducing the radio output of the first cell and increasing the radio output of a second cell adjacent to the first cell if the rate of the first cell is predicted to reach the implementation level.

A steam turbine blade includes a coating film formed at least a portion of a surface of the steam turbine blade, the coating film containing a ceramic matrix and nanosheet particles dispersed in the ceramic matrix. The steam turbine blade is employed as one of stator blades or one of rotor blades in a steam turbine. The steam turbine includes a turbine rotor, the rotor blades implanted in the turbine rotor, the stator blades provided in an upstream side of the corresponding rotor blades, and a turbine casing supporting the stator blades and accommodating turbine rotor, the rotor blades and the stator blades. The steam turbine is also configured such that the rotor blades are paired with the corresponding stator blades to form turbine stages arranged in an axial direction of the turbine rotor, thereby forming steam paths.
