Abstract: A near-infrared absorbing glass is provided and includes 10% to 40% by weight of phosphorus and 5% to 35% by weight of iron, where a molar ratio of phosphorus to iron (P/Fe) of the near-infrared absorbing glass is between 1.75 and 5, and the near-infrared absorbing glass has an average transmittance of less than 10% to light with wavelengths ranging from 930 nm to 950 nm. A near-infrared cut-off filter including the near-infrared absorbing glass is also provided.

Abstract: A system of concentrating and separating waste solvent liquid includes a distillation tower, an extracting distillation unit, an extract agent recovery unit, and a vapor permeation film unit. The scheme of centrifugal distillation is specifically employed to collocate with vapor permeation to effectively concentrate the content of isopropanol in the waste solvent liquid to generate a final produce with ultra high concentration of isopropanol, and constantly recovers the extract agent. The system is able to be quickly settled to a steady state of operation with low power consumption because the extracting distillation unit has smaller size. Since no liquid is left in the extract agent recovery unit, operation risk is greatly reduced. In addition, the input feed is almost processed, overall efficiency is thus improved. The vapor permeation film unit further removes considerably little content of water from the organic solvent to increase the content of isopropanol up to 99.9% or more.

Abstract: A nerve impulse signal stimulation device and a method for fabricating the same are provided. The nerve impulse signal stimulation device includes: a substrate having a first surface and a second surface opposite to the first surface; a first metal layer formed on the first surface of the substrate; a second metal layer formed on the first metal layer; a plurality of openings exposing a portion of the first surface of the substrate, a portion of the first metal layer and a portion of the second metal layer; and a ferromagnetic material attached to the second surface of the substrate. The openings cause the nerve impulse signal stimulation device to obtain a parallel circuit structure, thereby increasing the current load and the magnetic field intensity, reducing the size of the device, and ensuring the safety of operations.
