    摘要: An automatic and continuous method is presented to improve the accuracy of fiber optic distributed temperature measurements derived from Raman back scatterings utilizing two light sources with different wavelengths, by choosing the wavelengths of the two sources so the primary source's return anti-Stokes component overlaps with the incident wavelength of the secondary light source thereby canceling out the non-identical attenuations generated by the wavelength differences between Stokes and anti-Stokes bands.

    摘要: Disclosed herein is a linear compressor wherein a compression unit, including a cylinder and a linear motor, is supported by a frame mounted in a hermetic container. The frame is die cast using diamagnetic zinc having a high forming accuracy, thereby preventing an electromagnetic force of the linear motor from being leaked therethrough, and enabling a reduction in the number of machining times thereof after die casting.

    摘要: Disclosed herein is a linear compressor having a stator cover, which is designed in such a fashion that a section of the stator cover not to be fastened with bolts has a curvature smaller than the remaining section thereof to be fastened with the bolt so as to be reduced in size thereof. This enables the stator cover to be spaced apart from the shell by a sufficient distance, thereby achieving a size reduction of the shell and a small-scale linear compressor.

    摘要: Disclosed is a method of providing a desired range of point-to-ground resistance to trays, by making a conductive pathway between both surfaces of the tray after forming and cutting processes. A desired range of point-to-ground resistance of the tray can be achieved by partially or entirely coating a conductive solution composed of a conductive polymersuch as polyaniline, polypyrrole, polythiophene and derivatives such as poly 3,4-ethylenedioxythiophene and mixtures thereof, metal powders and flakes composed of iron, copper, aluminum and other metals, metal oxides such as doped tin oxide and indium oxide, onto cut surfaces of the tray, by attaching a conductive or semi-conductive tape to top and bottom surfaces of the tray so as to cross them, or by using a metal clip. Thereby, a desired range of point-to-ground resistance can be provided to the tray by electrically connecting the top and bottom surfaces of the tray.
