Abstract:
A discharge detection apparatus includes a vacuum container, a conductive installation member in the vacuum container, the installation member being connected to the vacuum container so as to be retained by the vacuum container; a conductive antenna in the vacuum container; and a retainer comprising a material having a specific resistance of 1×105 to 1×1011 (Ω·cm), the retainer retaining the antenna with respect to the installation member without a contact between the installation member and the antenna, by means of a screw located through an inside of the antenna and an inside of the retainer.
Abstract:
An ozone supplying apparatus according to an embodiment of the present invention is an ozone gas supplying apparatus which supplies an ozone gas to a vacuum apparatus. The ozone supplying apparatus includes an ozone generator configured to generate the ozone gas, a first flow controller configured to control a flow rate of the ozone gas generated by the ozone generator, a second flow controller configured to control a flow rate of the ozone gas supplied to the vacuum apparatus, and a main pipe provided on a secondary side of the first flow controller and on a primary side of the second flow controller, with the ozone gas being introduced into the main pipe at such a flow rate that an internal pressure of the main pipe is controlled to be lower than atmospheric pressure by the first flow controller.
Abstract:
A heat transfer plate according to the present embodiment includes a first heat transfer unit transferring heat generated in a member mounted on the first heat transfer unit, the heat being generated due to shaping or controlling of a beam generated by a light source in a decompressed atmosphere, a second heat transfer unit provided around the first heat transfer unit, and a plurality of third heat transfer units making the first heat transfer unit movable with respect to the second heat transfer unit, the plurality of third heat transfer units connecting the first and second heat transfer units.
