    摘要： A switch includes a base, a fixed contact member having fixed contact, and a movable contact member having a movable contact. The movable contact member moves in a first direction to bring the movable contact into contact with the fixed contact, and moves in a second direction opposite to the first direction to separate the movable contact from the fixed contact. The switch further includes a cover, an elastic body that energizes the movable contact member in the second direction, and an operation body configured to move the movable contact member sequentially to a first position, a second position, and a third position.

    摘要： The present invention provides a method and device for three-dimensional reconstruction, applied to the field of image processing. The method comprises: obtaining a first depth map, which is photographed by a first photographic device, and obtaining a second depth map, which is photographed by a second photographic device; merging the first depth map with a first three-dimensional model according to a position of the first photographic device to obtain a second three-dimensional model; and merging the second depth map with the second three-dimensional model according to a position of the second photographic device to obtain a third three-dimensional model. By adoption of the method, during the reconstruction of three-dimensional images, the reconstruction effect of the three-dimensional images of the top and the bottom of the target object can be improved, and the precision of the reconstructed three-dimensional images is improved.

    摘要： A multistage centrifugal compressor includes a casing, a rotor including a plurality of impellers, a diaphragm defining a gas flow path that includes a return flow path, and at least one liquid injection device configured to inject liquid into the gas flow path. The liquid injection device includes a liquid injection path, an internal path, a chamber, and a plurality of nozzles. The liquid injection path penetrates through the casing at a position corresponding to a return bend. The internal path receives a liquid supply pipe inserted from the liquid injection path through the return bend. The chamber is provided in the diaphragm along a circumferential direction and the liquid is introduced into the chamber through the internal path. The plurality of nozzles inject the liquid introduced into the chamber, to the gas flow path from different positions of the chamber in the circumferential direction.

    摘要： A rotary machine includes a thrust bearing and radial bearings rotatably supporting a rotary shaft, a rotation drive portion that rotates the rotary shaft, a first-stage impeller that rotates about an axis of the rotary shaft, a casing, a working fluid gas extraction portion that extracts a working fluid under compression from a middle of the first-stage impeller to an outside of the casing, and a working fluid supply line that allows the working fluid under compression, on which gas extraction is performed by the working fluid gas extraction portion, to be supplied therethrough to the rotation drive portion.
