Abstract: Equipment for manufacturing a separator plate for a fuel cell comprises: a press which receives a conveyed first metal strip and second metal strip, vertically arranges the metal strips side by side, and forms patterns on each of the first metal strip and the second metal strip; a welding machine which overlaps the first metal strip and the second metal strip conveyed from the press, and integrally joins the metal strips by welding same in a state in which the patterns are aligned face-to-face with each other; and guide rolls which are arranged in front of and behind the press and guide the first metal strip so that the first metal strip is supplied to the welding machine at an overlapping position with the second metal strip after passing through the press at a position spaced vertically apart from the second metal strip.

Abstract: An embodiment pattern electrode structure for an electrowetting device includes a first branch electrode disposed in a direction perpendicular to any plane that is perpendicular to a plane defined by the pattern electrode structure and a basal pattern electrode disposed in an area above an upper end of the first branch electrode and connected to an electrode connection portion configured to receive a voltage, wherein an interval between the first branch electrode and the basal pattern electrode is equal to or larger than a diameter of a droplet to be removed.

Abstract: A pattern electrode structure for an electrowetting device is laminated between a base material and a dielectric layer of the electrowetting device, and the pattern electrode structure includes first branch electrodes formed in a direction perpendicular to any plane perpendicular to a plane defined by the pattern electrode structure, and a basal pattern electrode formed in an area below lower ends of the first branch electrodes and connected to an electrode connection portion configured to receive a voltage, in which a sum of an interval between the first branch electrode and the basal pattern electrode and a width of the basal pattern electrode is larger than a diameter of a droplet to be removed, thereby preventing the droplet from stagnating without falling at the terminal end of the pattern in a structure that uses the vertical pattern.

Abstract: A non-contact interface device for a vehicle and a method for controlling the same, may display an operation system menu for a driver and passengers to operate various kinds of devices of the vehicle as a hologram, enable a user to operate the displayed operation system menu in a non-contact manner by use of the user's finger or the like, and provide the user with a tactile feedback for a non-contact operation, so that the user can recognize whether to have operated the menu.

Abstract: A bispecific molecule according to an embodiment includes a B7-H3 antibody or an antigen-binding fragment thereof, and a transforming growth factor beta (TGF?) binding portion bound thereto. The bispecific molecule is bispecifically bound to B7-H3 and TGF? and thus can be utilized as an immune checkpoint inhibitor for various diseases including cancer.

Abstract: A B7-H3 antibody or antigen-binding fragment thereof includes a heavy chain variable region including heavy chain complementarity determining regions (HCDRs) and a light chain variable region including light chain complementarity determining regions (LCDRs). The B7-H3 antibody has a predetermined complementarity determining region, thereby specifically binding to a B7-H3 antigen, and being internalized into cells, and being usable as an immune checkpoint inhibitor for various diseases.

Abstract: Disclosed is a vacuum cleaner having a structure for preventing foreign matter from entering between a drum brush and a bearing. A vacuum cleaner includes a suction portion formed with a suction port through which air and foreign matter are sucked. The suction portion includes a housing and a drum brush rotatably provided in the housing. The drum brush includes a rotating drum rotating by receiving a driving force and a brush mounted on the rotating drum. The housing is provided with an annular blocking rib, and the brush located at one end of the drum brush is configured to be accommodated in the blocking rib.

Abstract: As to the method for fabricating a member of a vehicle, after a member for the vehicle having high-rigidity of martensite organization is fabricated by a hot stamping forming, the martensite organization is transformed to a ferrite having a low-rigidity partially and improved toughness or to a metal organization heat treated by tempering process through induction heating or secondary heat treatment using laser beam of conduction area, and thereby collision absorption performance is improved by stabilizing the absorption directivity of the collision energy without additional reinforcement.

Abstract: The present invention provides a laser welding method for steel sheets. The laser welding method includes irradiating a low heat input laser beam to a weld zone with a uniform welding pattern of a zigzag shape, with a constant pitch, and with a constant welding speed, so that autogenous welding may be achieved without a feed wire, such that cost of material may be reduced and joinability and performance may be improved.
