A catalyst for exhaust gas purification includes (1) a monolithic carrier having passages and (2) palladium-loaded alumina obtained by immersing alumina in a palladium solution and then firing the resulting alumina and loaded on the monolithic carrier as a catalyst layer. In the catalyst, the catalyst layer loaded on the partition walls of the passages of the monolithic carrier has a thickness of 5 to 100 &mgr;m and the palladium/alumina (Pd/Al2O3) weight ratio in the catalyst layer is 0.03 to 0.30. This catalyst is a Pd-only catalyst improved in hydrocarbon purifiability during the cold start of engine.

摘要:
A reformer includes two or more catalyst units in the flow path, capable of generating hydrogen from a reactant fluid containing an organic compound or carbon monoxide, by catalysis. In the reformer, at least two of the catalyst units satisfy the following relationship: Heat capacity of the upstream-side catalyst unit≦Heat capacity of the downstream-side catalyst unit. The reformer is improved in the relationship between these catalyst units with respect to heat capacity. This improvement leads to improvement of the reformer in safety, heating characteristics during the start-up period, efficiency of hydrogen production and reduction in production of CO as the coproduct.

In a method and device for molding a laminated molded assembly by simultaneously forming a resin core member and integrally joining a surface skin member in a die assembly for mold press forming comprising an upper die and a lower die, the moldability of the surface skin member is improved by softening the surface skin member by blowing hot air against the surface skin member from air holes provided in the upper die which is associated with the surface skin member. As a result, the surface skin member can favorably conform to the surface contour of the die surface and the resin core member. Optionally, vacuum suction may be applied to the surface skin member to draw it against the corresponding die surface so as to eliminate the possibility of creating localized gaps between the surface skin member and the corresponding die surface. Further, by blowing air of either high temperature or ambient temperature from the air holes provided in the upper die to facilitate the removal of the laminated molded assembly from the upper die, the speed of the molding process can be increased, and the damages and deformation of the laminated molded assembly can be avoided.

The present invention provides a compact recording and reproducing apparatus capable of playing back DVD and CDs including CD-R. This apparatus comprises a means of focusing a light of a first or second wavelength onto a first or second recording media; a first means disposed off the optical axis of the focusing means to generate a light of the first wavelength; a second means disposed on the optical axis of the focusing means to generate a light of the second wavelength; a means of correcting a coma aberration in the light of the first wavelength and guiding the corrected light along the optical axis of the focusing means, and a means of detecting the light of the first or second wavelength reflected from the first or second recording media.
摘要:
A recording-medium reproducing apparatus in which different types of recording mediums can be reproduced by the single reproducing apparatus. The apparatus selectively reproduces information from a first recording medium by applying light to an information recording layer through a transparent substrate having a first thickness, and reproduces information from a second recording medium by applying light to an information recording layer through a transparent substrate having a second thickness. The apparatus has a light-generating device for generating light to be applied to the information recording layer of the recording medium. A light-applying device converges the light generated by the light-generating device and applies it to the information recording layer of the recording medium. A light-receiving device, which is divided into a central portion and a peripheral portion, separately receives the light reflected by the recording medium.
摘要:
A vehicle wheel is of a three-piece sandwich type and high in accuracy and rigidity and can be manufactured less expensively and more efficiently. The radially outer portions of the flanges of an inner rim part and an outer rim part, which constitute a rim assembly for supporting a tire, are located in contact with each other outside the peripheral edge of a disk in the radial direction thereof so that the portions constitute a butted part. The rim parts are clamped to each other by bolts and nuts in such a manner that the radially inner portions of the flanges pinch the flange of the disk on both the sides of the latter flange. The butted part is provided with a welding seal on the peripheral surfaces of the flanges of the rim parts.
