In general, the present invention incorporates a cooling or heating wrap having internal channels to circulate a chilled or warmed fluid, with one or more layers of a thermo-conductive material to eliminate air pockets or gaps between the wrap and a human or animal body part. The thermo-conductive material may be applied directly to the human or animal skin and / or body part, may be encapsulated in a separate unit, or may be integrated into the wrap itself. The thermo-conductive material acts like a heat conduction medium between the heat exchanging wrap and the anatomical body part, to increase the therapeutic effect of the wrap.

Solid state modules and fixtures comprising different combinations and arrangements of a light source, one or more wavelength conversion materials, thermally conductive connection adapters allowing dissipation of heat outside of the module, and a remote power supply unit. This arrangement allows for greater thermal efficiency and reliability while employing solid state lighting and providing emission patterns that are equivalent with ENERGY STAR® standards. Some embodiments additionally place compensation circuits, previously included with power supply units, on the optical element itself, remote from the power supply unit. Various embodiments of the invention may be used to address many of the difficulties associated with utilizing efficient solid state light sources such as LEDs in the fabrication of lamps or bulbs suitable for direct replacement of traditional incandescent bulbs or fixtures using bulbs.

Disclosed is an electroconductive fiber comprising synthetic fibers and an electroconductive layer covering the surface of the synthetic fibers and containing carbon nanotubes. Not less than 60% (particularly not less than 90%) of the total surface of the synthetic fibers is covered with the electroconductive layer, and the electric resistance of the electroconductive fiber is in the range of 1*10<-2> to 1*10<10> Omega / cm, and the standard deviation of the logarithm of the electric resistance is less than 1.0. The thickness of the electroconductive layer is in the range of 0.1 to 5 micrometers, and the amount of the carbon nanotubes may be 0.1 to 50 parts by mass based on 100 parts by mass of the synthetic fiber. The electroconductive fiber may contain a binder. The electroconductive fiber may be produced by immersing the synthetic fibers in a dispersion while applying vibration to the synthetic fibers to deposit an electroconductive layer on the surface of the synthetic fibers. In the electroconductive fiber, the carbon nanotubes are deposited evenly and strongly onto substantially the whole area of the surface of the fibers, and, thus, the electroconductive fiber is electroconductive and flexible.

Disclosed is a quick ice-making control method of an ice-maker for a refrigerator, in which an ejector for extracting obtained ice stirs supplied water to be frozen so as to promote thermal transmission of the water. The quick ice-making control method includes the steps of (a) supplying water into an ice-maker mold, (b) quickly freezing the water by rotating an ejector for a predetermined time after the step (a), and (c) separating the obtained ice from the ice-maker mold in case that a temperature of the ice-maker mold is lower than a predetermined temperature after the step (b).
