  • Patent number: 10994579
    Abstract: A towing device for connecting an automatic guided vehicle to a carriage is disclosed. When connecting an automatic guided vehicle to a carriage, a swing arm is moved toward a connecting member by a moving device, whereby the swing arm is engaged with the connecting member to thereby regulate the swiveling (swinging) of the connecting member with respect to the automatic guided vehicle. Furthermore, after the automatic guided vehicle is connected to the carriage, the swing arm is moved in a direction away from the connecting member by the moving device, whereby the engagement between the swing arm and the connecting member is released, thereby allowing the connecting member to swivel (swing) with respect to the automatic guided vehicle.

  • Patent number: 8828272
    Abstract: A phosphor includes a crystal phase of a formula (Ln,Ca,Ce)3+?Si6N11. In this formula, ? is from ?0.1 to 1.5, inclusive. When an object color of the phosphor is expressed by the L*a*b* color system, the value of (a*2+b*2)1/2 satisfies 71?(a*2+b*2)1/2. Also in the formula, Ln is La, Gd, Lu, Y, Sc, or any combination of these. When the phosphor is excited with light having a wavelength of 455 nm, it emits a color wherein x is from 0.400 to 0.570 inclusive, and y is from 0.420 to 0.590, inclusive, as expressed in the CIE standard coordinate system.

  • Patent number: 7905304
    Abstract: An automatic guided vehicle drive device includes a top plate member, a drive unit, a holding plate member and a turning shaft mechanism. The drive unit has left and right wheel axles attached to left and right wheels, respectively. The holding plate member is coupled between the top plate member and the drive unit to pivotally hold the drive unit with respect to a movement direction. The turning shaft mechanism is coupled between the top plate member and the holding plate member to turnably support the drive unit about a vertical line passing through an intersection between an axial centerline of the wheel axles and a middle line oriented in the movement direction and passes through an approximate middle position between the wheel axles while exerting a force along the vertical line in a direction of separating the drive unit from the top plate member via the holding plate member.
