  • Patent number: 10029298
    Abstract: A chuck device in a robot hand is used when receiving a primary formed workpiece from electrode chucks. After receiving the primary formed workpiece, and before inserting the primary formed workpiece from its shaft stem part into an insertion hole in a forging press main body, a portion held by the electrode chucks of the primary formed workpiece is gripped by a chuck device different from the chuck device, to release the gripping of the primary formed workpiece by the chuck device. Therefore, it is possible to insert the holding portion held by the electrode chucks from the side of the shaft stem part of the primary formed workpiece into the insertion hole. Thereby providing a bar material transfer method capable of accurately inserting the bar material from its one end into a predetermined positioning hole even if a bar material serving as a workpiece is short.

  • Patent number: 9839793
    Abstract: An irradiation apparatus radiates a particle beam after forming the beam for plural layers. A dose monitor measures a dose in real time. A dose evaluation unit evaluates an irradiation dose for each layer on the basis of a value measured by the dose monitor and a dose calibration factor set for each layer. An irradiation control section performs radiation control for each layer on the basis of an evaluation result of the dose evaluation unit. An interpolation value generation unit uses actual-measurement dose-calibration factors obtained by radiating a particle beam to a simulated phantom provided with a calibration dosimeter, to generate an interpolation estimation value of the dose calibration factor. For each layer subject to the interpolation value, and based on an irradiation condition of that layer, the interpolation value generation unit performs weighting on each of the actual-measurement dose-calibration factors.

  • Patent number: 9499171
    Abstract: When a vehicle equipped with a driving support apparatus moves from an original traveling lane into a lane for passing in order to pass a preceding vehicle and an oncoming vehicle appears in the lane for passing, the safe passing of the preceding vehicle is determined to be impossible and the passing is interrupted even when the oncoming vehicle decelerates, in the case where a deceleration change amount of the oncoming vehicle is smaller than a threshold. On the other hand, when the deceleration change amount of the oncoming vehicle is equal to or greater than the threshold, whereby safety with respect to surrounding vehicles can be confirmed, and it is determined the vehicle can be safely returned in front of the preceding vehicle, the passing of the preceding vehicle is performed.

  • Patent number: 9493163
    Abstract: When an oncoming vehicle in an oncoming lane is detected in the case where a vehicle equipped with a driving support apparatus moves to a position across a portion of a boundary between an original traveling lane of the vehicle and the oncoming lane in order to pass a preceding vehicle, passing control is interrupted. When the departure of the oncoming vehicle from the oncoming lane is confirmed, the interruption of the passing control is canceled and the passing is performed. When the oncoming vehicle does not depart, or when it the oncoming vehicle is determined to depart but a vehicle following the oncoming vehicle is detected, the interruption of the passing control is maintained and the vehicle is returned to behind the preceding vehicle in the original traveling lane.

  • Patent number: 9416533
    Abstract: A device for damping a transmitted vibration by the moment of inertia of a fly wheel and the adjustable resistance force of a viscous magnetic fluid to allow the viscous magnetic fluid exerts its property even under no external power source. A sleeve with an attached ball nut is disposed in a first cylinder so as to reciprocate. The reciprocating motion of the sleeve is converted into a rotational motion by a ball screw to rotate a fly wheel in a second cylinder and a generator rotating shaft. Between the fly wheel and the inner surface of the second cylinder, a sealed space is formed in which a viscous magnetic fluid is sealed. A magnetic field generating unit which generates a magnetic field running across the sealed space with the fly wheel serving as a part of a magnetic circuit is disposed on the inner circumference of the second cylinder.
