Disclosed is a substrate processing apparatus capable of suppressing generation of plasma in the space between a moving electrode and an end wall at one side of a cylindrical chamber. The substrate processing apparatus includes a cylindrical chamber to receive a wafer, a shower head movable along a central axis of the chamber inside the chamber, a susceptor opposing the shower head in the chamber, and a flexible bellows connecting the shower head to a cover of the chamber, wherein a high frequency power is applied to a processing space presented between the shower head and the susceptor, processing gas is introduced into the processing space, the shower head and the side wall of the chamber are non-contact to each other, and a bypass member is installed electrically connecting the shower head and the cover or the side wall of the chamber.

A substrate processing apparatus includes a chamber accommodating a wafer, a susceptor disposed inside the chamber and on which the wafer is held, an upper electrode facing the susceptor, and a second high frequency power source connected to the susceptor, wherein the upper electrode is electrically connected to a ground and is moveable with respect to the susceptor. The substrate processing apparatus divides a potential difference between plasma generated in a processing space and the ground into a potential difference between the plasma and a dielectric and a potential difference between the dielectric and the ground by burying the dielectric in the upper electrode, and changes a gap between the upper electrode and the susceptor. Accordingly, plasma density between the upper electrode and the susceptor is changed.

A distance between electrodes can be accurately measured by using a lifter. A substrate processing apparatus includes an upper electrode 120 and a lower electrode 310 facing each other within a processing chamber 102; a lift pin 332 that is protrusible from and retractable below the lower electrode and lifts up a substrate mounted on the lower electrode to be separated from the lower electrode; a lifter 330 that elevates the lift pin up and down; and a controller 400 that elevates the lift pin upward and brings the lift pin into contact with the upper electrode by driving the lifter while the substrate is not mounted on the lower electrode and measures a distance between the electrodes based on a moving distance of the lifter.

A filter medium for an air filter collecting dust in an air flow has a principal collection layer including a porous polytetrafluoroethylene film. A surface of the filter medium is provided with a plurality of embossed projections. Preferably, a processed filter medium maintains a zigzag shape by pleating an unprocessed filter medium to create mountain folds and valley folds. Preferably, an air filter unit includes such a processed filter medium and a frame body holding the processed filter medium.

Provided is a heat treatment furnace, which includes a processing vessel configured to accommodate at least one object to be processed, a heat insulating member configured to cover a periphery of the processing vessel, and a heating unit configured to be arranged along an inner peripheral surface of the heat insulating member. The heat insulating member includes an inner heat insulating member and an outer heat insulating member formed independently of the inner heat insulating member. The outer heat insulating member contains a finely-powdered compressed silica material, and at least an outer surface thereof is covered with an anti-scattering member configured to prevent the finely-powdered compressed silica material from being scattered.

An overhead transport vehicle comprises a travelling unit that travels on a rail, a conveying unit that moves and conveys an article and a swing inhibiting member that moves between a pushing position and a retracting position. The swing inhibiting members includes a pushing member that pushes a side surface of the article, lever members that support the pushing member at a first end side and are pivotally supported by the conveying unit at a second end side, and a biasing member that biases the pushing member toward the article. The pushing member includes a main body member pivotally supported by the lever members, slide members slidably supported by a main body member, and elastic bodies arranged between the main body member and the slide member that slide elastically the slide member.

When a function inactivation process is instructed on an MFP A, all the functions are inactivated and a function inactivation certification key is issued, and then resources related to the functions are transmitted to an MFP-B. When reception of the resources is completed on the MFP-B, a function duplication completion certification key is issued. When these keys are input to a licensing server, a database is updated, and a function activation key is issued. When the function activation key is input to the MFP B, the functions related to the transmitted resources are carried out.
