Abstract:
Disclosed is a medical mask apparatus using optical fibers which can selectively project a laser beam to an entire treated portion or a local portion of skin. A medical mask apparatus using optical fibers for projecting a fine laser beam to the skin to activate skin cells and expedite circulation of blood in the skin includes: a laser light source generator for generating and supplying a laser beam having a predetermined wavelength band; a plurality of optical fibers branched from the laser light source generator; and a mask body having a cover portion having a predetermined area such that the cover portion covers a portion of a face and in which a portion of a distal end of the optical fiber is exposed along the entire cover. An electro-optic material is coated on an output end of the optical fiber such that an output of the output end of the optical fiber is controlled by an external electrical signal, and the output end of the optical fiber has a diameter smaller than that of an input end of the optical fiber connected to the laser light source generator such that fine projection is allowed.
Abstract:
The present invention relates to a pyrolysis device using a liquid metal including: a hollow reactor in which the liquid metal is received; a circulating pump connected to the reactor; a buffer tank disposed on an upper portion of the reactor and receiving the liquid metal from the circulating pump; a nozzle coupled with the buffer tank and jetting the liquid metal within the buffer tank into the reactor; and an air supply source supplying air to the liquid metal within the reactor, wherein char generated from fuel injected into the reactor is combusted by reacting with air introduced into a lower portion of the reactor through the air supply source, and liquid metal sprays jetted from the nozzle react with gases generated in the reactor to purify the gases.
Abstract:
The present invention relates to a method of producing biofuel, more specifically a method of producing biofuel comprising the steps of generating monosugars from marine algae, or from polysaccharides extracted from marine algae by treating the marine algae or the polysaccharides with a hydrolytic enzyme and/or a hydrolytic catalyst; and fermenting the monosugars using a microorganism to produce biofuel. The method of producing biofuel of the present invention solve the problem of raw material suppliance since it uses marine algae as a raw material for biomass, and reduce the production costs by excluding lignin eliminating process that has been required by the conventional method using wood-based raw materials, resulting in economic and environmental advantages.
Abstract:
The present invention provides a hybrid gasification system which simultaneously has the advantages of an entrained-flow gasifier using pulverized fuel and a fluidized-bed gasifier utilized for gasifying fuel with relatively various properties. The present intention provides a hybrid gasification system employing a structure in which a second reaction chamber operated at a temperature of 700 to 900 is surrounded by a first reaction chamber operated at temperature, thereby obtaining an insulation effect, performing additional heat exchange, and minimizing a heat loss. Furthermore, the present invention provides a hybrid gasification system having a structure in which unreacted substances and tar within synthetic gas generated from a first reaction chamber reacts within a second reaction chamber, thereby increasing the entire gasification efficiency.
Abstract:
Disclosed herein is an ultrasonic extrusion apparatus which causes resonance of an extrusion die using ultrasonic vibrations, thus reducing friction between the extrusion die and an extrusion material. The ultrasonic extrusion apparatus has an increased number of ultrasonic vibrators provided around the extrusion die in the circumferential direction to increase the vibration output, whereby when extruding a metal material such as a magnesium material, friction between the metal material and the extrusion die can be reduced, thus improving the performance of the extrusion process (preventing a reduction in an extrusion rate, generation of heat, cracking of a product, errors in measurements, etc.).
Abstract:
An apparatus for selecting a motion signifying artificial feeling is provided. The apparatus includes: an feeling expression setting unit configured to set probabilities of each feeling expression behavior performed for each expression element of a robot for each predetermined feeling; a behavior combination generation unit configured to generate at least one behavior combination combined by randomly extracting the feeling expression behaviors in each expression element one by one; and a behavior combination selection unit configured to calculate an average for the probabilities of the feeling expression behaviors included in each behavior combination for each feeling of a robot and select behavior combinations in which the average of the probabilities of the feeling expression behaviors most approximates the predetermined feeling value of a robot from each behavior combination.
