Abstract: Disclosed is a pipe-type fire extinguishing equipment for extinguishing a fire inside a ship transport container, including: an agent storage part installed inside the container and storing a fire extinguishing agent for extinguishing a fire; a supply pipe installed on an upper portion inside the container and connected to the agent storage part to receive and guide the fire extinguishing agent; spray holes communicating with the supply pipe and spraying the fire extinguishing agent, which flows through the supply pipe, to the inside of the container; opening/closing members which keep the spray holes closed and open the spray holes upon being melted by heat when a fire occurs; and an alarm sound generation unit connected to the supply pipe and generating an alarm sound by means of the fire extinguishing agent which is supplied to the supply pipe when the fire extinguishing agent is sprayed through the spray holes.

Abstract: Provided is a cam type press capable of controlling deformation of a flange of a panel in the course of processing the flange, thus reducing deformation such as a crease, or the like, of the flange. The cam type press includes a padding cam installed to be movable in a slope direction. A slider is installed to be movable toward the padding cam, with a process gap into which a portion of a panel is inserted to form a flange between one side of the padding cam and one side of the slider. An adjustment block adjusts the process gap provided between the other side of the padding cam and the other side of the slider.

Abstract: Provided is a radar signal processing method and apparatus for compensating for an in-phase/quadrature-phase (I/Q) imbalance, the method including extracting a real part of a radar signal in which an I/Q imbalance occurs through a conversion of an in-phase (I) channel signal of the radar signal, extracting an imaginary part of the radar signal through a conversion of a quadrature-phase (Q) channel signal of the radar signal, extracting an error due to the I/Q imbalance based on the real part and the imaginary part, and outputting a correction signal obtained by compensating for the I/Q imbalance of the radar signal based on the error.
