  • Publication number: 20190202139
    Abstract: An adhesive injection method is for injecting an adhesive that bonds an outer plate and a reinforcing member. The reinforcing member has through holes bored through the reinforcing member in a direction intersecting a bonding surface facing the outer plate. The method includes positioning the outer plate and the reinforcing member; disposing a sealing material covering a gap between the outer plate and the reinforcing member; and injecting the adhesive into the through holes in order from one end to the other end of the bonding surface. At the injecting, while the adhesive is injected into the through hole, when the adhesive is recognized through another through hole formed adjacent to the through hole into which the adhesive is being injected, a through hole into which the adhesive is to be injected is shifted from the through hole into which the adhesive is being injected to the other through hole.

  • Patent number: 10289102
    Abstract: After selecting a robot for carrying out a welding operation at a given welding spot, the cross-section of a welding gun with which that robot is provided and the cross-section of a workpiece at the welding spot are compared. Furthermore, a determination is made as to whether or not welding is possible without the welding gun and the workpiece coming into contact. When it is determined to be impossible, a substitute robot for carrying out the welding of the welding spot is selected. With the present invention, the automatic selection of the robot for carrying out the welding operation for the welding spot becomes possible. Therefore, the number of steps for robot selection can be reduced.

  • Patent number: 10175683
    Abstract: The present invention relates to a teaching data preparation device and a teaching data preparation method for an articulated robot. Pre-existing position data that approximates new position data is retrieved from a database that, from among data related to working points for a pre-existing workpiece, stores for each working point pre-existing position data that indicates the position of the working point and pre-existing orientation data that indicates the orientation of an end effector at the working point. Next, pre-existing orientation data that is associated with the retrieved pre-existing position data is extracted. Next, incomplete new orientation data is completed using the extracted pre-existing orientation data. As a result of this series of processes, the precision of teaching data can be improved.

Projections of the first claw and the second claw defines a left-right width of a mouth. A third claw projects into the retaining space at a position closer to the base end of the first arm, and a fourth claw is provided which projects into the retaining space at a position closer to the base end of the second arm. The third claw is narrower than the first claw in their widths along a front-back direction orthogonal to the depth direction of the retaining space extending from the mouth to the bottom and the left-right width direction of the mouth.

  • Publication number: 20180243854
    Abstract: According to the present invention, a plurality of actual spots where normal directions of welding surfaces are parallel to each other and arranged successively, are set as a spot group. Then, when the actual spots included in the spot group are collectively moved in the same direction by the same distance, a search is conducted of candidates for the directions and the distances that cause the actual spots having been moved to approach welding points. Further, optimum direction and distance are selected from among the candidates for the directions and distances, and a plurality of teaching points corresponding to the plurality of actual spots included in the spot group are corrected by using the selected direction and distance.

  • Publication number: 20180056429
    Abstract: A spatter production information storage unit stores spots where spatter has been produced. For the spots where spatter has been produced, a comparison information generation unit acquires weld design information stored in a design information storage unit and weld instruction information stored in an instruction information storage unit, compares both pieces of information, and generates comparison information. An image information output unit outputs the generated comparison information to a display device. The display device displays the comparison information on a screen so as to allow checking by an operator. Hence, it is possible to check, on the screen, comparison information for weld instruction information and weld design information highly likely as a cause for spatter being produced, and to efficiently perform the task of analyzing the causes for spatter being produced.

  • Patent number: 9688770
    Abstract: A human antibody or a functional fragment thereof having specific binding ability to CD98 which is derived from the cell membrane of cancer cells and is in the form of a complex with a protein having an amino acid transporter activity (for example, LAT1) is disclosed. This antibody binds to CD98 in the form of a dimer with LAT1 on the surface of cancer cells, specifically attacks cancer cells expressing CD98 via the immune system by ADCC or CDC, and further inhibits amino acid uptake of the cancer cells via LAT1, to suppress growth of the cancer cells. Accordingly, a preventive and therapeutic agent for cancer comprising this antibody or a fragment thereof, which acts on various cancers, is specific to cancer, and causes no side effect, is provided.

  • Patent number: 9593467
    Abstract: An inexpensive engine assist device capable of performing stable energy regeneration from an accumulator and a working machine on which the engine assist device is mounted are provided. A variable capacity type main pump and a variable capacity type assist pump are directly connected to an engine. A return pressure oil flowing out from a fluid pressure actuator is temporarily accumulated by a sub-accumulator and is supplied to an inlet of the assist pump, and the assist pump pressurizes the return fluid pressure oil and supplies the return fluid pressure oil to a main accumulator. A controller calculates and controls an assist pump swash plate angle, and assist starting torque or charge starting torque, and introduces a pressure-accumulated fluid discharged from the main accumulator to the inlet of the assist pump or introduces a pressurized fluid discharged from an outlet of the assist pump into the main accumulator.

  • Patent number: 9526302
    Abstract: There is provided a cover-material fastening clip for connecting a cover material and a cushion material. An engaging part engaged with the cover material. A hook is provided below the engaging part and is formed with: a claw-shaped part engaged with a wire provided in a groove of the cushion material; and a jig receiving part engaged with a jig for separating the hook from the wire. A position at which the jig receiving part is engaged with the jig is located at a side opposite to the engaging part relative to a position at which the hook is engaged with the wire. When the jig is engaged with the jig receiving part and is pulled up, the clip is rotated about the wire and the wire is separated from the claw-shaped part, so that the connection between the cover material and the cushion material is released.

  • Patent number: 9394929
    Abstract: In order to avoid cavitation in a boom cylinder head end at the beginning of a dig cycle, fluid from an alternate source is supplied to the head end before or in addition to fluid supplied by the main boom-up hydraulic circuit. In one embodiment, an electronic hydraulic valve, related sensors, and control system determines the beginning of a dig operation and uses fluid at an intermediate pressure to rapidly provide fluid to a boom head end cylinder to prevent voiding or cavitation before fluid under high pressure from the main pump can be brought to the cylinder. An on/off fluid switch is activated early in a dig operation to address low pressure at the boom cylinder head end and provide an alternate path for fluid into the cylinder in reaction to the boom being lifted by a motion of the stick and bucket in contact with the work surface.
