  • Publication number: 20240121809
    Abstract: A method of a first terminal may include: identifying first RB set(s) to be used for SL communication among consecutive RB sets through an LBT procedure; identifying a first subchannel group included in the first RB set(s) and a second subchannel group including a first PRB in the first RB set(s), the first PRB being not included in the first subchannel group; configuring the first PRB within the second subchannel group as an SL communication resource; and transmitting, to a second terminal, control information indicating that the first PRB is configured as the SL communication resource.

  • Patent number: 11261759
    Abstract: A turbine support structure supports a turbine casing and is configured to be movable when the turbine casing is thermally deformed while a gas turbine is operated, thus preventing a fatigue fracture of the turbine casing from occurring. The turbine support structure includes a pair of supports, each having an upper and lower end, for supporting respective opposite side surfaces of the turbine casing at the upper end of either support; and a movable unit installed at the lower end of each support and configured to movably support the lower end of the support. The movable unit is spaced outwardly from the corresponding opposite side surface of the turbine casing, so that the corresponding support inclines toward the turbine casing and is rotatable. The lower end of each support is rotatably coupled to the corresponding movable unit so that the support is rotatable toward an axis of the turbine casing.

  • Patent number: 10648350
    Abstract: A retainer for a gas turbine blade that inhibits deviation of a rotating blade mounted on a rotor of a gas turbine, can include: a retainer frame disposed at one side of the rotating blade and configured to form an inside chamber through which cooled air is introduced, between the retainer frame and the rotating blade; a barrier wall formed between the retainer frame and the rotating blade and configured to divide the inside chamber into a plurality of cooling chambers; and a fixing unit disposed at one side of the retainer frame and configured to fix the retainer frame to the rotor.

  • Patent number: 9784491
    Abstract: Provided is a driving device for an automatic ice-making machine, the driving device including: a cam gear that rotates a tray; and an operating lever that organically operates along a cam plane for an ice-cube quantity detecting arm formed at the cam gear and allows the ice-cube quantity detecting arm to rotate downward into an ice-cube storage bin, wherein a cam groove for the ice-cube quantity detecting arm is formed in the cam plane for the ice-cube quantity detecting arm of the cam gear and allows the operating level to descend so that the ice-cube quantity detecting arm rotates downward into the ice-cube storage bin, and a protrusion is formed between the cam plane for the ice-cube quantity detecting arm and the cam groove for the ice-cube quantity detecting arm and allows the operating lever to ascend so that the ice-cube quantity detecting arm that rotates downward into the ice-cube storage bin rotates upward.
