摘要： An air filter, a method for manufacturing the same, and also a high efficiency air cleaning apparatus employing the same are disclosed. The air filter includes a supporter and an inorganic material layer that is formed by fixing the powder of the fraipontite mineral to the surface of the supporter, using the powder of an inorganic substance as a binder. The method for manufacturing the filter includes the steps of immersing a supporter in a suspension in which the powder of the fraipontite mineral and the powder of an inorganic substance as a binder are dispersed as the suspensoid, and drying the supporter impregnated with the suspensoid, thereby forming an inorganic material layer fixed to the surface of the supporter. The fraipontite mineral adsorbs and removes gaseous acid or basic impurities in the air while the inorganic substance as a component of the inorganic material layer works as an adsorbent against gaseous organic impurities contained in the space of the air cleaning apparatus.

摘要： A method for forming dendritic metal powders, comprising the steps of: (1) heating a powder comprising non-dendritic particles, under conditions suitable for initial stage sintering, to form a lightly sintered material; and (2) breaking the lightly sintered material to form a powder comprising dendritic particles. In one embodiment, the lightly sintered material is broken by brushing the material through a screen. Another aspect of the present invention comprises the dendritic particles that are produced by the method described above. These particles can comprise any suitable metal, such as transition metals, rare earth metals, main group metals or metalloids or an alloy of two or more such metals. The particles can also comprise a ceramic material, such as a metal oxide. These particles are characterized by a dendritic, highly anisotropic, morphology arising from the fusion of substantially non-dendritic particles, and by a low apparent density relative to the substantially non-dendritic starting material. The present dendritic particles can be of high purity, and substantially free of carbon contamination.

摘要： A laminated filter material for removing foreign materials from gas or liquid with high precision, its fabricating method and a filter using a laminated filter material are described. The laminated filter material comprises a support member of porous metal and a particle layer of fine particles laminated on a surface having asperities of the support member, by immersing the support member in a suspension of the particles without a binder, and evacuating the suspension through the support member. The method for fabricating includes the steps of preparing a suspension of particles finer than the average pore diameter of support member without using a binder, immersing the support member, and evacuating the suspension through the support member. The filter has a housing for supporting the laminated filter material, wherein the housing is provided with a metal attachment part having a surface contacting an end-face of the laminated filter material, and the attachment part and end-face of the laminated filter material are fixed by fusing the particle layer from the reverse side of the contacting surface of the attachment part.
