Abstract: The element joint is obtained by joining: a long pipe; a short pipe made of a quality of material having a strength equal to or higher than a strength of the long pipe; and a plate material made of a quality of material having a strength equal to or higher than a strength of the short pipe. In the element joint, at least one member of the long pipe and the short pipe includes a pipe-shaped portion, and the pipe-shaped portion of the one member is pipe-expanded and joined to the other member by press-fitting. The short pipe and the plate material are welded to each other.

Abstract: A blade operation control part of a blade control device controls operation of a blade such that when a blade load is equal to or less than a first load threshold value and a position deviation is equal to or greater than a position threshold value, the blade is lowered to make the position deviation approach zero. The blade operation control part controls operation of the blade such that the blade is raised regardless of the position deviation when the blade load is equal to or greater than a second load threshold value.

Abstract: Provided is a hot filament CVD device capable of performing coating treatment on a base material while stably correcting slack of a filament due to thermal expansion. The hot filament CVD device includes a chamber, a base material support that supports multiple base materials, multiple filaments, a first frame, a second frame, a power source, a drive unit, a drive control unit, a calculation unit, and a temperature information acquisition unit. The temperature information acquisition unit acquires information on temperature of the multiple filaments, the temperature changing with application of voltage. The calculation unit calculates an amount of thermal expansion of the multiple filaments based on the acquired information on temperature. The drive control unit causes the second frame to move apart from the first frame in accordance with the amount of thermal expansion calculated by the calculation unit.
