  • Publication number: 20220227005
    Abstract: An article boxing system includes an image processing apparatus, a first robot, and a first controller. The image processing apparatus detects edges of an article based on an image of the article. The image processing apparatus calculates information relating to a conveyance state. The first robot includes a hand unit and an arm adjusting three-dimensional coordinates and an inclination of the hand unit with respect to a conveyance direction. The first controller controls an operation of the arm to move the hand unit in correspondence with the information relating to the conveyance state and causes the hand unit to adsorb the article, when the article reaches an operation range of the first robot.

  • Publication number: 20060232017
    Abstract: A metal gasket for a cylinder head has two base plates each constructed from a metal plate and layered over each other, an auxiliary plate constructed from a metal plate and interposed between the base plates, and hard metal-plated layers. The base plates each have cylinder holes, annular beads, coolant holes, and an outer peripheral bead. The cylinder holes correspond with the bore of each cylinder. The annular beads have an angled cross-sectional shape. The coolant holes correspond with a coolant jacket of the cylinder block and with a coolant hole of the cylinder head. The outer peripheral bead has a cross-sectional shape sloping on one side and surrounds the beads and the coolant holes. Each of the layers is extended from a position more radially inward than an annular bead of a base plate to a position radially outward.

  • Patent number: 7114889
    Abstract: A powdery particle conveying system is provided in which electric power consumption can be saved when powdery particles are conveyed by use of a roots blower. In the case where the powdery particles are conveyed to a reservoir tank near the roots blower, the frequency of a power source of a roots blower driving motor is reduced, thereby reducing an output of the roots blower. In contrast, in the case where the powdery particles are conveyed to a remote reservoir tank, a voltage of a commercial frequency is applied to the motor.

  • Patent number: 6810726
    Abstract: Equipment for testing wheel durability in which the marginal portion of the rim portion of the wheel is mounted to the rotary disk with one end of the moment shaft and the spindle shaft corresponding to the axle being mounted to the disk portion of the wheel. The rotary disk is rotated in a state in which a load is applied to the other end of this moment shaft for thereby evaluating the durability of the wheel. The marginal portion of the wheel is mounted to the rotary disk while pressing with the pressing member obtained by dividing a ring-shaped plate into two. The pressing member permits the mounting of the wheel to the rotary disk with an uniform pressing force in the circumferential direction and prevents rattling, local deformation and the like of the wheel.
