  • Patent number: 11970213
    Abstract: A reinforcement, joined by welding to a vehicle structural member having a closed cross section, comprising a curved section at least in part of its length, a top wall having opposite edges, and a pair of lateral walls extending from the edges to form ridge lines, wherein the top wall and the lateral walls form a U-shaped cross section. The lateral wall includes a base surface and a plurality of welding projections at intervals along its length, each welding projection having a raised surface for welding. Each welding projection is raised from the base surface of the lateral wall toward the vehicle structural member. The lateral wall further includes a bead between the welding projections within a curved section to prevent or suppress wrinkles from forming during press forming. The bead is raised from the base surface of the lateral wall toward the vehicle structural member.

  • Publication number: 20240133990
    Abstract: A positioning system includes an elevation angle calculator that determines, as a second elevation angle, an inverse cosine of a first value, upon occurrence of a condition in which an absolute value of a first elevation angle is greater than or equal to a second predetermined angle, the second predetermined angle being greater than a first predetermined angle, the first value being obtained by dividing a second value that is obtained by correcting, with a correction value, an altitude measured by an altitude measurement unit, by a distance measured by a distance measurement unit. The elevation angle calculator selects any one of the first elevation angle and the second elevation angle, based on a value of the first elevation angle.

  • Patent number: 11932770
    Abstract: A method for producing a resin sintered body 1 by applying an ink 3 to thermoplastic resin powder 2 and sintering the powder, the method including the step of immersing an intermediate resin sintered body 1m, which has an unevenly colored region on the surface thereof and the whole of which has been already sintered, in a surface treatment liquid containing sulfuric acid and chromic anhydride, in which the concentration of chromic anhydride is 300 g/L or more, for 5 minutes or longer. When producing a resin sintered body by sintering thermoplastic resin powder, the surface of the resin sintered body can be evenly and sufficiently colored to an extent required without an unevenly colored region on the surface thereof, and also the surface of the resin sintered body can have a good appearance and smoothness.

  • Patent number: 9581992
    Abstract: In a conventional CAM apparatus, cutting regions and a tool axis angle by which the cutting time is minimized cannot be automatically set for a finish shape having a free formed surface shape. Accordingly, the CAM apparatus generates quadrangle-shaped patterns of cutting regions using coordinate data of a finish shape and an initial shape. Triangle-shaped cutting regions are generated for concave-convex faces of the finish shape. For cutting regions generated by subtraction by boolean operation with a subtract shape calculated by subtraction by boolean operation between the initial shape and the finish shape, the tool axis angle is set so that the tool does not interfere and the face is maximized. For other regions, the tool axis is set so as to satisfy a remainder standard and to minimize a tool path length.

  • Patent number: 9547301
    Abstract: In order to easily verify an operation of the machine tool, a machining support apparatus includes a machining monitoring unit 112, a simulation processing unit 113, and a display unit 150. The machining monitoring unit 112, upon receiving a notification indicating detection of a simulation start code programmed in a machining program from a machine tool controller controlling a machine tool via a communication device 130, renders the machine tool controller to stop the machine tool. The simulation processing unit 113 simulates instructions from the simulation start code to a simulation end code in the machining program, while the machine tool is stopped. And the display unit 150 displays a simulation performed in the simulation processing unit.

  • Patent number: 8542835
    Abstract: When a network pages the temporary user mobile identifier of a mobile station, the mobile station sends a response to the network. Next, the network checks the authenticity of the user using a ciphering key, corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated, a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong, the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication, the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition, diversity handover is commenced upon a call attempt. Furthermore, if a branch replacement is necessary, the current branch is replaced by new branches capable of executing the diversity handover.
