A device of executing vacuum processing is provided with: a chamber including a single main chamber executing the vacuum processing and being capable of keeping the chamber in a depressurized state; a feeding roller so disposed as to hang down a reinforcement fiber in the main chamber; a winding bobbin winding the reinforcement fiber, the winding bobbin disposed in the chamber horizontally apart from the reinforcement fiber vertically hung down; and a swing body pivotally supported in the chamber to swing about a pivot and including a suspension arm capable of capturing and suspending the reinforcement fiber according to a swing motion of the swing body, the suspension arm is capable of swinging from a first position horizontally apart from the reinforcement fiber vertically hung down, via a second position for capturing the reinforcement fiber, to a third position to suspend the reinforcement fiber above the winding bobbin.

Vacuum processing device

A device of executing vacuum processing is provided with: a chamber including a single main chamber executing the vacuum processing and being capable of keeping the chamber as a whole in a depressurized state; a plurality of feeding rollers so arranged as to hang down a plurality of threads in the main chamber with keeping the threads from each other; a plurality of winding bobbins respectively winding the plurality of threads independently, the winding bobbins arranged in the chamber horizontally apart from the plurality of threads vertically hung down; and a plurality of movable arms being respectively movable in the chamber from a first position horizontally apart from the plurality of threads vertically hung down, via a second position in contact with any of the plurality of threads, to a third position to make the threads in contact be in contact with corresponding winding bobbins.

Provided is a centrifugal compressor, including: a movable member which is movable between a first position and a second position, the first position being a position at which an opening degree of an auxiliary flow passage arranged more on an outer diameter side than a main flow passage becomes a first opening degree, the second position being a position at which an opening degree of the auxiliary flow passage becomes a second opening degree smaller than the first opening degree; and a linear actuator configured to drive the movable member in a rotation axis direction of the impeller.

Centrifugal compressor

A centrifugal compressor includes: a compressor housing in which an intake passage is formed; a compressor impeller provided in the intake passage; an actuator that causes a rod to linearly move in a direction intersecting with a rotation axis direction of the compressor impeller; a connection member connected to the rod; a throttle member including a protruding portion; a connection shaft extending in the rotation axis direction and connecting the connection member and the throttle member; and a rotation shaft extending in a direction parallel to the connection shaft and serving as a rotation center of the throttle member.

Throttle mechanism for centrifugal compressor and turbocharger

An oscillation jig includes: an oscillation jig base connected to an oscillation table; a first clamp member provided in the oscillation jig base; a second clamp member located at a position opposed to the first clamp member in an oscillation direction and configured to hold a first metal component together with the first clamp member; a link mechanism provided in the oscillation jig base, composed of a plurality of links connected together, connected to the second clamp member, and caused to extend and contract in the oscillation direction; and a clamp actuator configured to cause the link mechanism to extend and contract in the oscillation direction. When the first clamp member and the second clamp member hold the first metal component, a connection center line connecting connection centers of the respective links is made straight in the oscillation direction.
