  • Patent number: 11933310
    Abstract: A main-body casing having an inlet port or an outlet port, a rotatable rotor shaft, and a rotor coupled to the rotor shaft are provided. A recess portion opened toward the inlet port is formed in the rotor and a fastening portion (a first shaft portion and a second shaft portion) of the rotor shaft is exposed to the recess portion. A cover portion, which is fastened to the fastening portion by a cover-portion fixing bolt and covers at least a part of the recess portion, is formed having a container shape and has a reinforcing portion located in a periphery of the fastening portion that prevents deflection by increasing rigidity. The cover portion also has a contact-pressure generating portion which is pressed by fastening to the fastening portion in a fastening direction and causes a contact pressure to be generated in the fastening direction.

  • Patent number: 7981230
    Abstract: Two prisms bonded together in a bonding step are then, in a pressing step, put onto a joining jig and pressed to be formed into an optical device. The joining jig has a pair of holding plates arranged opposite each other and a precision plate held between parts of the directly opposite surfaces of the holding plates. In the pressing step, the two prisms are pressed with the surface of one of the prisms placed in contact with the surface of the precision plate exposed to the gap between the holding plates, with another surface of the same one of the prisms placed in contact with the directly opposite surface of one of the holding plates, and with the surface of the other of the prisms placed in contact with the directly opposite surface of the other of the holding plates. Thus, the two prisms move along the oblique surface of each other, and are pressed onto the directly opposite surfaces of the holding plates.
