摘要:
A highly clean and high temperature valve apparatus includes a valve driving unit and a valve casing connected to a bonnet supporting a valve stem slidably. A stem portion has one end positioned in a circumferential wall closed at its two ends by upper and lower covers, and supports one end of the valve stem with its other end extending through the lower cover. The stem portion has its ends supported respectively by first and second bellows for closing an axial through hole of the lower cover tightly. A first pipe communicates with a first space isolated by the first bellows, and a second pipe communicates with a second space isolated by the first bellows. The fluid quantities in the first and second spaces are increased or decreased relative to each other, thereby to drive the stem portion supported in a floating state by the first and second bellows.

Provided is a deposition apparatus for organic EL capable of allowing vapor of a film forming material to be vapor deposited on a target object to be uniformly heated. A deposition apparatus, which performs a film forming process by vapor depositing a film forming material on a target object in a depressurized processing chamber, includes an evaporating head having a vapor discharge opening, disposed in the processing chamber, for discharging vapor of the film forming material. Inside the evaporating head, provided is a heater receiving member which is sealed with respect to an inside of the processing chamber, and installed is a communication path which allows the heater receiving member to communicate with an outside of the processing chamber. A power supply line for a heater received in the heater receiving member is disposed in the communication path and extended to the outside of the processing chamber.

A control valve device develops opening/closing accuracy of a valve assembly. The valve head 310a is configured to open and close a transfer path formed in the valve housing 305 by transmitting the power to the valve assembly 310 from the power transmission member according to a pressure ratio between working fluid supplied to the first space Us and the second space Ls, respectively. The valve head has a Vickers hardness larger than a Vickers hardness of a valve seat of the transfer path to be in contact with the valve head, and a hardness difference therebetween is set to be about 200 Hv to about 300 Hv.
摘要:
[Problem] To provide a regulating valve device having a valve element opened or closed by a working fluid.[Solution to Problem] A valve element 310 has a structure in which a valve head 310a and a valve body 310b are coupled by a valve stem 310c. In the valve box 305, the valve element 310 and a power transmitting member 320a are slidably housed. A first bellows 320b is fixed to the power transmitting member 320a and the valve box 305 to form a first space Us at a position on a side of the power transmitting member 320a opposite the valve element. A second bellows 320c is fixed to the power transmitting member 320a and the valve box 305 to form a second space Ls at a position on a side of the power transmitting member 320a closer to the valve element. According to a ratio of air supplied to the first space Us from a first pipe 320d and air supplied to the second space Ls from a second pipe 320e, the power transmitting member 320a transmits power to the valve head 310a to open or close a transport channel 200a.
摘要:
A deposition apparatus includes a deposition source unit, a transport mechanism for transporting a vaporized film forming material and a blowing device for blowing off the transported film forming material. The deposition source unit includes a vapor deposition source assembly, a housing and a water cooling jacket. The vapor deposition source assembly includes a gas supply mechanism, a gas inlet and a first material evaporating chamber formed as one body. A heater of the housing heats a film forming material in the first material evaporating chamber and the carrier gas flowing in a plurality of gas passages. The vaporized film forming material is transported by an argon gas. The water cooling jacket is installed apart from an outer peripheral surface of the housing at a certain distance and cools the deposition source unit.

There is provided a substrate processing system having high maintainability by widening a gap between various processing apparatuses connected with side surfaces of transfer modules and capable of achieving sufficient productivity by avoiding deterioration in throughput. The substrate processing system for manufacturing an organic EL device by forming a multiple number of layers including, e.g., an organic layer on a substrate includes at least one transfer module configured to be evacuable and arranged along a straight transfer route. Within the transfer module, a multiple number of loading/unloading areas for loading/unloading the substrate with respect to a processing apparatus and at least one stocking area positioned between the loading/unloading areas are alternately arranged along the transfer route in series, and the processing apparatus is connected with a side surface of the transfer module at a position facing each of the loading/unloading areas.
摘要:
Provided are amorphous silica particles for application to industrial fields where there are increasing desires for high purity and colorlessness. The amorphous silica particles are produced through the steps of hydrolysis of an alkoxide, vacuum drying, and firing. The amorphous silica particles have been reduced in coloration and in Fe content, which is causative of coloration of the silica, and can meet the desires. The amorphous silica is characterized by having an Fe content of 20 ppm or less.

There is provided a deposition head capable of discharging a material gas having a uniform flow rate and equi-thermal property from each component in a large-sized substrate as well as a conventional small-sized one for forming a uniform thin film. A deposition apparatus including the deposition head is also provided. The deposition head is provided within a deposition apparatus for forming a thin film on a substrate and configured to discharge a material gas toward the substrate. The deposition head includes an outer casing, and an inner casing provided within the outer casing and into which the material gas is introduced. In the inner casing, an opening configured to discharge the material gas toward the substrate is formed, and a heater configured to heat the material gas is provided at an outer surface of the outer casing or in a space between the outer casing and the inner casing.
