A substrate processing apparatus includes: a depressurizable processing chamber 11; a shaft 26 supporting a facing electrode 24 provided within the processing chamber 11 while allowing the facing electrode 24 to be movable with respect to a mounting electrode 12; a first ring-shaped bellows 31 concentrically installed at an outer peripheral portion of the shaft 26; and a second bellows 32 concentrically installed at an outer peripheral portion of the first bellows 31. The first bellows 31 absorbs a displacement of the facing electrode 24 with respect to a wall surface 13 at a penetration portion where the shaft 26 penetrates the wall surface 13 of the processing chamber 11, and seals the inside of the processing chamber 11 against the ambient atmosphere around the shaft 26. A ring-shaped gas flow path 35 is formed by the first bellows 31 and the second bellows 32.

A projector includes: an illuminating device including a light source device, a first lens array that comprises first regions located at four corners in the first lens array when viewed along a system optical axis and second regions located between the two first regions, and a second lens array; a light modulating device; a projection optical system; a light control device; and a mode selection device. The light control device blocks part of the plural partial light beams by causing first and second light shields to integrally operate, when the brightness priority mode is selected. The light control device always blocks part of the partial light beams with the first light shields and blocks part of the partial light beams by causing the second light shields to operate independently from the first light shields.

The disclosure provides a spectrophotometer, including a light source for irradiating light into a sample gas, a photodetector for detecting light transmitted through the sample gas, an optical filter, and an operation device for calculating a concentration of an actual gas to be measured, contained in the sample gas based on a detection signal value obtained from the photodetector. The operation device calculates the concentration of the actual gas based on function a for associating a concentration of a substitute gas with the actual gas obtained from a reference instrument, function β for associating a relation between a light absorption of the actual gas and the substitute gas in the reference instrument, with a relation between a light absorption of the actual gas the substitute gas in a calibration instrument, and a function indicating a relation between the concentration of the substitute gas and the detection signal value.

The present invention provides a liquid crystal panel that can provide a neutral display that is free from coloring in every direction. The liquid crystal panel includes a first polarizer 14a, a second polarizer 14b, and a liquid crystal cell 13. The first polarizer 14a is arranged on the visible side of the liquid crystal cell 13 and the second polarizer 14b is arranged on the backlight side of the liquid crystal cell 13. The liquid crystal panel further includes a first retardation layer 11 and a second retardation layer 12. A refractive index ellipsoid of the first retardation layer 11 has a relationship of nx=ny>nz, and a refractive index ellipsoid of the second retardation layer 12 has a relationship of nx>ny≧nz. The first retardation layer 11 and the second retardation layer 12 are arranged between the liquid crystal cell 13 and the second polarizer 14b.
摘要:
A substrate processing apparatus that can reduce the number of parts. A first gas introduction hole through which the hydrogen fluoride gas is introduced into a GDP is formed in an upper lid. A second gas introduction hole through which hydrogen fluoride gas is introduced from a hydrogen fluoride gas source is formed in a processing vessel. When the upper lid engages the upper portion of the processing vessel, one end of the first gas introduction hole is joined with one end of the second gas introduction hole to form an introduction path through which the hydrogen fluoride gas is introduced into a chamber.
