  • Publication number: 20240102745
    Abstract: Heat exchanger comprising a pair of header tanks which are arranged to be spaced apart from each other, a plurality of tubes formed in two columns in the width direction so that both ends are connected to the pair of header tanks, and a plurality of fins interposed between the tubes and coupled to the tubes. The header tank is configured so that a first tank and a second tank are respectively coupled to one header having a central bent portion in the center portion in the width direction, which provides easy assembling of headers and tanks of two heat exchangers. Thermal stress caused by the temperature difference between two heat exchanging media is blocked so that damage to a coupling portion where the two heat exchangers are coupled or a bonding portion formed through brazing can be prevented. Thus, leakage of the heat exchanging medium can be prevented.

  • Patent number: 10665087
    Abstract: The present invention relates to a control system and method. The control system includes worker devices worn by workers to detect and transmit location information, external information, and biometric information and a control server checking the external information and the biometric information detected by the worker devices and determining whether an accident has occurred. The control server selectively transmits an evacuation or rescue order to worker devices around an accident location according to a cause and a range of the accident.

  • Patent number: 10205973
    Abstract: The method may include initiating a view of real-time broadcasting content at a broadcasting reception terminal; determining a view suspension time point in response to a user input during the real-time broadcasting; transmitting, to a history management server, view history data comprising the view suspension time point and content identification information, the transmitted view history data interacting with a non-real-time video service server; requesting the non-real-time video service server for non-real-time broadcasting content corresponding to the real-time broadcasting content; and receiving the non-real-time broadcasting content that is provided from the non-real-time video service server and corresponds to a broadcasting time after the view suspension time point. A bi-directional multimedia service free from restrictions on a place and a time may be achieved by providing a substantially real-time video service through a linkage between a real-time broadcasting and a non-real-time video service.

  • Patent number: 7093603
    Abstract: A skin treating implement, a callus removing hand piece, is used to remove skin calluses. The hand piece is connected to a vacuum suction device. The hand piece has a main body that is bent at a certain degree for greater usability. Below the bend, there is a detachable mount for a cutter with a desired shape. In the upper part of the main body, connectors with nipples can be mounted to be inserted into a suction tube connectable to a vacuum device to ensure compatibility with the suction device. Because the lower portion of the main body of the hand piece is bent, it facilitates removing calluses and permits mounting and unmounting cutters permitting a choice of cutter appropriate for the king of callus to be removed. Connectors with nipples of suitable diameters permit use of suction tubes of existing high-priced vacuum suction devices to make the callus removing hand piece economical. A disposable sheet fixer injection molded with synthetic resins is attachable to the cutter.
