  • Publication number: 20230416013
    Abstract: A bolt escapement device includes holding rails, a blade disposed downstream of the holding rails, and a chute disposed downstream of the blade. The blade includes: a blade body configured to reciprocate in a direction intersecting the holding rails to pass through a first position and a second position; a bolt passageway extending in the blade body in a direction acute to a moving direction of the blade body; and a closure portion provided on a side surface of the blade body. At least one of the holding rails and the chute is provided with bolt guides. When the blade body moves from the first position to the second position, a corner portion of the bolt passageway that is closer to the holding rails is inserted between a bolt having entered the bolt passageway and a subsequent bolt and the rail gap is closed by the closure portion.

  • Patent number: 9796025
    Abstract: A main spindle device includes: a main spindle; a rod accommodated in the main spindle, the rod being capable of moving to an unclamp position in a direction toward the first end, and when the main spindle is holding a tool, being capable of moving to a clamp position in a direction toward a second end; a biasing unit that biases the rod in the direction toward the second end with respect to the main spindle and that biases the rod to the clamp position when a collet is holding the tool; and a biasing force detector that detects a biasing force of the biasing unit which biases the rod in the direction toward the second end after the rod is moved in the direction toward the first end with respect to the main spindle to the unclamp position by force larger than the biasing force of the biasing unit.

  • Patent number: 9310596
    Abstract: A compound microscope device allows simultaneous observation of one specimen by a transmission electron microscope and an optical microscope. The compound microscope device 1 of the present invention has a transmission electron microscope 2 and an optical microscope 4. A specimen 10 and a reflection mirror 41 are disposed on an electron optical axis C of an electron ray. The reflection mirror 41 is inclined from the electron optical axis C toward the optical object lens 43 and the specimen 10. Light from the specimen 10 (fluorescent light, reflection light, and the like) is reflected by the reflection mirror 41 and enters into the optical object lens 43. The electron ray from the electron microscope 2 passes through a mounting center hole 42 of the reflection mirror 41. This makes it possible to observe one specimen simultaneously by the electron microscope 2 and the optical microscope 4.

  • Patent number: 8905419
    Abstract: A rear structure of a saddle-ride type vehicle for preventing rainwater or the like splashed by a rear wheel from entering a fresh air inlet of an engine intake system. The rear structure of a saddle-ride type vehicle includes a rear fender halved into a first fender and a second fender connected to each other. The first fender is formed with a hanging portion so as to cover the rear and upside of a rear wheel and the second fender covering the upside of the rear wheel with a fresh air inlet being provided lateral to and in front of the rear wheel. The first fender and the second fender are disposed to overlap each other in an anteroposterior direction. The second fender is disposed on the vehicle-widthwise inside of the first fender. The second fender has anteroposteriorly and downwardly extending sidewalls at both vehicle-widthwise lateral end portions.

  • Patent number: 7929105
    Abstract: To prevent inconsistency in images and support columns from collapsing when pressure is applied from outside in the case where liquid crystal is sealed in under negative pressure in order to prevent impact bubbles from being created in the liquid crystal display device in accordance with a liquid crystal dropping and sealing method. The distance between a TFT substrate 10 and a facing substrate 20 is set using first support columns 30, while second support columns 40 are located within contact holes 50 and do not make contact with the TFT substrate 10. When pressure is applied from outside, the second support columns 40 make contact with the side wall or the like of the contact holes 50 created in the TFT substrate 10, so that the repulsive force of the second support columns 40 prevents the distance between the TFT substrate 10 and the facing substrate 20 from becoming too small.
