摘要： A process of microcellular foam molding an article includes using a modifier to modify properties of amorphous PLA, pouring the modified amorphous PLA into a high pressure vessel, dissolving an SCF in the high pressure vessel to impregnate the modified amorphous PLA in the high pressure vessel which is configured to allow the SCF to effuse through, forming foamed pellets, conveying the foamed pellets to a mold in a second vessel filled with water or oil, heating the second vessel, and cooling the second vessel until a foamed article is finished in the mold.

摘要： The present invention provides a hybrid Raman/EDFA optical amplifier that utilizes a first optical detector that generates a first electrical or electronic signal that is proportional the combined optical power of the signal light and the leaked pump laser light, a second optical detector that generates a second electrical or electronic signal that is proportional to the power of the pump laser light and an electronic subtraction circuit that receives the first and second electrical or electronic signals and generates a difference signal that is proportional to only to the optical power of the signal light and insensitive to the power of the Raman pump laser light. The difference signal is utilized by an EDFA control circuit to control and/or adjust the operation of the EDFA based upon changes in the power of the input optical signal.

摘要： A process of making a sole includes mixing a foaming material with a nucleating agent to form a plurality of local blanks belonging to different portions of a sole wherein the local blanks belonging to different portions have different ratios of the nucleating agent; injection molding the local blanks to form a plurality of cold molds which are joined together along a horizontal direction to form a sole blank; sulfurizing the sole blank; and subjecting the sole blank to supercritical foaming to produce a finished sole.
