Abstract:
A linear compressor is provided. The linear compressor may include a cylinder in which refrigerant flows in an axial direction, a piston that reciprocates within the cylinder so as to compress the refrigerant, and a linear motor that drives the piston. At least one of the cylinder or the piston may be sintering molded.
Abstract:
The present invention discloses a mounting structure of a linear compressor, comprising: a shell which is a hermetic space, a connection terminal for supplying power being fixed to one side of the shell; a main body frame installed in the shell, one end of a cylinder forming a compression space for compressing a refrigerant with a piston being fixed to the main body frame; and a motor cover, a linear motor comprised of an inner stator, an outer stator and a mover, for reciprocating the piston by a mutual electromagnetic force being fixed to the outer circumference of the cylinder, the outer stator being bolt-fastened between the main body frame and the motor cover. Here, the main body frame is left-right symmetric.
Abstract:
The present invention discloses an oil supply valve assembly of a linear compressor including a shell, the oil being stored at the lower portion of the shell, a cylinder disposed in the shell, a piston disposed in the cylinder, a main body frame to which the cylinder is fixed, and a linear motor connected to the piston, for driving the piston, comprising: a passage formed in the main body frame, for supplying the oil to a gap between the cylinder and the piston; an oil valve being coupled to the main body frame to communicate with the passage, and including an oil suction valve and an oil discharge valve; and an oil cover coupled to overlap with the oil valve and communicate with the passage of the main body frame. By this configuration, the manufacturing process of the oil supply valve assembly is simplified and mis-assembly of the components is prevented by reducing the number of the components.
Abstract:
Disclosed is a method for preparing a high dense aluminum nitride (AlN) sintered body. The method includes the steps of preparing powders for the AlN sintered body comprising Y2O3 of 0.1 to 15 wt %, TiO2 of 0.01 to 5 wt % and MgO of 0.1 to 10 wt %, and obtaining the AlN sintered body with a volume resistivity of 1×1015 Ωcm or more at a normal temperature and a relative density of 99% or more. The sintered body is obtained by sintering the powders and then cooling the sintered powders or sintering the powders and then cooling the sintered powders with annealing the sintered powders during the cooling.

Abstract:
A reciprocating compressor comprises a casing including a suction pipe (SP) through which a fluid is introduced from the outside and a discharge pipe (DP) through which the fluid is discharged outside and forming a predetermined internal space; a compressor main body (700) positioned in the casing (100), compressing the fluid introduced through the suction pipe (SP) with a linear reciprocating motion of a piston (420) and discharging the compressed fluid through the discharge pipe (DP); and a supporting unit (600) including a plurality of coil springs connecting the compressor main body (700) to the casing (100), wherein the plurality of coil springs (610, 620) includes, respectively, end coils (590) tightly wound so as to be fixed to one surface of the compressor main body (700) and to one surface of the casing (100) and an inner coil (580) having at least one part which is tightly wound and positioned between the end coils (590), thereby minimizing the lateral vibration of the compressor, which is generated in a direction that a reciprocating motor is operated in operation of the reciprocating compressor.
Abstract:
A method for high-speed image processing based on graphic processing unit includes processing an input image for the image processing in a texture format of a 32 bit floating point, and performing a predetermined algorithm for the image processing on the input image through at least one or more Framebuffer Object (FOB) and outputting the result as texture data.
Abstract:
A residual gas removing device for a gas supply apparatus in a semiconductor fabricating facility, includes a low stress valve disposed between a mass flow controller and a chamber. The low stress valve alternately supplies or cuts off a gas from the mass flow controller to the chamber. A WF6 gas removing apparatus is in flow communication with a gas inlet line of the low stress valve to remove a residual WF6 gas in the gas inlet line, before proceeding with a subsequent deposition step.
