摘要:
A composite molded article suitable as an automobile ceiling material is made of a nonwoven fibrous mat wherein inorganic monofilaments having a length of 10 to 200 mm and a diameter of 2 to 30 micrometers are partially bonded with a thermoplastic resin binder, many voids being provided throughout the mat and a large number of fine holes communicating with the voids in the inside being formed in at least one surface of the mat.
摘要:
A metal hydride heat pump system comprising a plurality of operating units, each operating units comprising a combination of a first metal hydride having a lower equilibrium dissociation pressure at an operating temperature and a second metal hydride having a higher equilibrium dissociation pressure at the operating temperature in such a manner that hydrogen can flow freely between the two metal hydrides, wherein the equilibrium dissociation pressure characteristics of one or both of the first and second metal hydrides in a given operating unit differ from those of one or both of the first and second metal hydrides in at least one other operating unit.
