摘要:
Exhaust purifying filter material which can carry a larger amount of catalyst and from which the catalyst will not easily drop off even if subjected to vibrations or temperature changes due to repeated heating and cooling at high temperatures. Catalyst is carried on alumina whiskers formed on metal fiber having a composition of Fe--Ni--Cr--Al, Fe--Cr--Al or Ni--Cr--Al or woven or unwoven fabric formed of the metal fiber. The catalyst is firmly carried by the alumina whiskers. The amount of catalyst carried is increased with the increase in surface area.

A method of forming a multilayered wiring board having a multilayered wiring structure includes the steps of forming a first mesh wiring layer having a plurality of holes therein, and forming a second wiring layer having a plurality of wirings undulating up and down so as to descend into the holes formed in the first wiring layer. In another method, the first wiring layer is formed with a plurality of protrusions and the wirings of the second wiring layer are formed between the protrusions. In the wiring boards formed according to the methods of the present invention, crosstalk between the wirings is suppressed.

This multilayered wiring board having a multilayered wiring structure includes a first mesh wiring layer having a plurality of holes therein, and a second wiring layer having a plurality of wirings. The wirings of the second wiring layer undulate up and down so as to descend towards the holes formed in the first wiring layer. In another arrangement, the first wiring layer has a plurality of protrusions protruding toward the second wiring layer at locations between adjacent ones of the wirings of the second wiring layer. In these wiring boards, crosstalk between the wirings is suppressed.
摘要:
The present invention provides a car exhaust purifying filter member which is high in the capacity to collect solid and liquid contents in exhausts and which has such high heat resistance as to be capable of withstanding heat when burned for cleaning and a method of manufacturing the same. A three-dimensional mesh-like metallic porous member made from Ni--Cr--Al and having a three-dimensional framework is heated at 800-1000 .degree. C. in the atmosphere to form on its surface a densely grown fibrous alumina crystal. This member is used as a filter member. Such a filter member shows excellent collecting capacity and corrosion resistance and can withstand high temperatures. Also, it is possible to firmly carry a catalyst on the fibrous alumina crystal formed on the surface. Because of its increased surface area, it has an increased catalyst carrying capacity.
