摘要:
The present invention is mainly configured of a separator for an electric double-layer capacitor that comprises an aramid fiber, a polyester fiber, a glass fiber, and a silica (inorganic compound for forming hydrosol) containing a particulate silica (particulate inorganic compound) of not less than 1 nm and not more than 500 nm, wherein total of the silica and the glass fiber is not less than 10 mass percent and not more than 50 mass percent; the electric double-layer capacitor comprising the separator; and a manufacturing method of the separator for the electric double-layer capacitor which method comprises a mixing process for mixing the aramid fiber, the polyester fiber, the glass fiber, and the silica sol and a paper making process for making paper from the mixture.
摘要:
An air filter element consists of an annularly arranged pleated filter medium having a plurality of radially extending pleats. Two sides or legs of each pleat are bonded to each other at the outer peripheral side to form an outer bonded section while one sides or legs of the adjacent pleats are bonded to each other at the inner peripheral side to form an inner bonded section, thereby forming a fluid path extending between the adjacent pleats along the length of each pleat. Additionally, outer and inner resilient seal members are so provided that a part of each outer bonded section is embedded in the outer seal member while a part of each inner bonded section is embedded in the inner sealing member.
摘要:
A multi-mode Raman laser system wherein Raman conversion is performed by injecting exciting laser beam from transversely excited atmospheric pressure CO.sub.2 laser system into a Raman cell. Unstable resonator type oscillator is used as transversely excited atmospheric pressure CO.sub.2 laser system; and multi-mode Raman cell is used as the Raman cell. The quantity required for an excited CO.sub.2 laser system can thus be extensively reduced. Also, it is possible to reduce the input electric required for obtaining the same energy of 16 .mu.m light which is scattered light, because saturated conversion of excited light, can be achieved by multi-mode Raman cell, and system efficiency can be increased.
摘要:
A multilayer filter medium, which is used as a constituent member of a filter and has a multilayer structure, includes a wet type nonwoven fabric layer A containing 0.5 to 20% by weight, based on layer weight, of short-cut nanofibers which are composed of a fiber-forming thermoplastic polymer, have a single fiber diameter (D) of 100 to 1,000 nm and are cut so that the ratio (L/D) of the length (L) to the single fiber diameter (D) is within the range of 100 to 2,500 and core-sheath conjugate type binder fibers having a single fiber diameter of 5 μm or more, and a nonwoven fabric layer B having a lower density than that of the wet type nonwoven fabric layer A. A filter uses the multilayer filter medium and has the nonwoven fabric layer B arranged on a fluid inlet side.
