A catalytic converter includes: a three-dimensional structural support having a plurality of cells partitioned by porous cell walls, in which a pore diameter of the cell walls is 10 &#x3bc;m to 50 &#x3bc;m and porosity of the cell walls is 40 vol % or more; and a catalyst-coated layer containing a catalyst component. The catalyst-coated layer is coated on surfaces of the cell walls of the three-dimensional structural support. 50 mass % or more of a total supported amount of the catalyst component on the three-dimensional structural support is present in a region from the surfaces of the cell walls of the three-dimensional structural support to surfaces of the catalyst-coated layer.

Catalytic converter and manufacturing method thereof

A rare earth magnet to be used in a motor. The rare earth magnet comprises rare earth magnet particles. Additionally, a rare earth oxide is present among the rare earth magnet particles, the rare earth oxide being represented by the following general formula (I):RR'O&#x2003;&#x2003;(I)where each of R and R&#x2032; is one element selected from the group consisting of yttrium (Y), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb) and lutetium (Lu), and 0&#x3c;x&#x3c;1.

A fiber body includes a collection of fibers containing thermoplastic resin as the main component and an energy consuming component, such as a piezoelectric material for converting and consuming external mechanical energy of sound and vibration. The energy is converted into electrical energy, which in turn, is converted and consumed into and as heat by means of the electrical resistance of the resin.

Energy conversion fiber and sound reducing material

A sound-absorbing duct structure for an intake system of an automotive internal combustion engine. The sound-absorbing duct structure comprises a duct defining thereinside a gas passage. A part of the duct is formed with a plurality of small holes. An expanded duct section is formed around the part of the duct. The expanded duct section defines therein an inside space which is in communication with the gas passage through the small holes. The inside space has a cross-sectional area larger than that of the gas passage. A sound-absorbing section is disposed in at least a part of the inside space of the first expanded duct section. The sound absorbing section includes a piezoelectric material exhibiting a piezoelectric effect, and an electrically conductive material in contact with the piezoelectric material.
