  • Publication number: 20150366070
    Abstract: The present invention relates to a preparation method for a dry film solder resist (DFSR) capable of forming the DFSR having fine unevenness on a surface by a more simplified method, and a film laminate used therein. The preparation method for a dry film solder resist includes forming a predetermined photo-curable and heat-curable resin composition on a transparent carrier film having a surface on which a fine unevenness having an average roughness (Ra) of 200 nm to 2 ?m is formed; laminating the resin composition on a substrate to form a laminated structure in which the substrate, the resin composition, and the transparent carrier film are sequentially formed; exposing the resin composition and delaminating the transparent carrier film; and alkaline-developing the resin composition in a non-exposure part and performing heat-curing.

  • Publication number: 20080159886
    Abstract: A scroll compressor uses fatty-acid ester oil for lubrication when a hydro-fluorocarbon (HFC) based-refrigerant is used, and uses fatty-acid mineral oil when a hydro-chlorofluorocarbon (HCFC)-based refrigerant is used. The driving motor is a synchronous reluctance motor with a rotor comprised of a plurality of flat plates. Each plate has a plurality of magnetic flux barriers that extend in both a circumferential direction and a radius direction. An insulation film formed of a crystalline plastic film is interposed between a coil and a stator of the motor, and the coil is formed of wire with an enamel coating layer. These features result in less deformation of the driving motor. In addition, losses due to slippage at the driving motor are lowered. Further, thermal loss due to emission of the rotor is decreased.

  • Publication number: 20080145252
    Abstract: A rotary compressor is provided which uses a synchronous reluctance motor to provide a driving force. The motor includes a rotor and a stator, each formed by a respective plurality of laminated steel plates. A plurality of magnetic flux barriers are formed on the steel plates which form the rotor, and a crystalline plastic film is disposed between the stator and a coil of the driving motor, the coil being implemented by an enamel coating layer. Accordingly, deformation of the rotor is decreased when the driving motor is assembled, and degradation of compressor performance due to slippage between the rotor and the stator is decreased, and heat emission of the rotor is decreased.

  • Patent number: 6241496
    Abstract: The present invention relates to a hermetic rotary compressor. More particularly, since the conventional rotary compressor has problems that the effect of a surge recess for reducing noises due to pressure pulsation is insufficient, and it is impossible to obtain the maximum compression efficiency, the present invention is constructed such that noises due to pressure pulsation can be reduced to the maximum and at the same time the compressive driving force required for compressing gaseous refrigerant is decreased to thereby improve the compression efficiency.
