  • Patent number: 10881364
    Abstract: The present invention relates to a portable carbon nanotube- and filament-type X-ray apparatus and a method for controlling same. The present invention comprises: a control unit for controlling a portable carbon nanotube- and filament-type X-ray apparatus; and a high-voltage apparatus, of an X-ray source, which is connected to the control unit, has carbon nanotubes (CNT) applied to the high-voltage apparatus of the X-ray source, enables a low-dose exposure by means of detailed control, enables significant reduction of power consumption due to omission of filaments, and has a high-voltage capacitor and a high-voltage diode structure disposed in a sandwiched structure such that the size of the high-voltage apparatus is reduced.

  • Publication number: 20140352176
    Abstract: Disclosed are a cushion for use in a shoe and a shock absorbing shoe having the cushion. The shock absorbing shoe includes: a sole having a lower surface thereof contacted with the ground; a cushion disposed above the sole; and an upper disposed above the cushion. The cushion includes: a rigid frame defining an inner region corresponding to the shape of at least a part of a foot of a wearer; and an elastic member supported by the frame and disposed in the inner region to support the foot of the wearer. The sole has a groove formed on an upper portion thereof in order to provide a deformation space for the elastic member.
