摘要:
An exhaust gas-purifying catalyst includes a support substrate, a catalyst support layer formed on the support substrate and containing a composite oxide of a rare earth element and zirconium, and a catalytic metal supported by the catalyst support layer. In this catalyst, all oxides containing the rare earth element are composite oxides of the rare earth element and zirconium in which the atomic ratio of zirconium to the rare earth element is 0.8 or more.

A catalyst for purifying exhaust gases includes a support including at le one composite selected from the group consisting of TiO.sub.2 --Al.sub.2 O.sub.3, ZrO.sub.2 --Al.sub.2 O.sub.3 and SiO.sub.2 --Al.sub.2 O.sub.3 composites, an NO.sub.x adsorbent including at least one member selected from the group consisting of alkali metals, alkaline-earth metals and rare-earth elements and loaded on the support, and a noble metal catalyst ingredient loaded on the support. The composites constituting the support improve initial NO.sub.x conversion of the catalyst, but also inhibit NO.sub.x purifying performance thereof from degrading even after a durability test.

摘要:
A process includes the step of bringing exhaust gases into contact with a catalyst, wherein the catalyst includes a support including a porous substance, at least one NO.sub.x adsorbent loaded on the support, and selected from the group consisting of alkaline-earth metals, rare-earth elements and alkali metals, and at least one element loaded on the support, and selected from the group consisting of copper and cobalt. The process enables the catalyst to exhibit superb NO.sub.x purifying performance even after a durability test and to stably and efficiently purify NO.sub.x during the fuel-lean side (i.e., the oxygen-rich atmospheres) driving.
摘要:
A delivery service management system utilizes a two-dimensional bar code having key information for specifying the source of a material and content information of this material and attached in a delivery service, a two-dimensional bar code having key information for specifying the source of an item obtained by processing the material and content information of the item and attached in a delivery service, and a two-dimensional bar code having key information for specifying a seller of the item and content information describing a selling condition of the item and attached in a delivery service. Every time a delivery service has occurred between the material system, the processing system, and the selling system, the key information and the content information are received from the two-dimensional bar code to a database. Delivery service information associated with a given source is fed back to the given source represented by the key information from a set of pieces of received information.

摘要:
A photo-pulse from a photo-pulse generating apparatus is branched, where one branch is radiated to an examined body and the reflected light reflected within the examined body is delayed in time in proportion to the depth from the surface of the examined body and is led to a time-analyzing reflected light measuring apparatus. In this measuring apparatus, the other branched reference photo-pulse or reference signal pulse is input as delayed by the time for which the photo-pulse reflected within the examined body returns and only the reflected light component synchronized with the entering timing of this reference light pulse is analyzed in the time and is detected. By varying the detection sensitivity of this measuring apparatus in response to the depth from the surface of the examined body, the interior can be observed.

摘要:
A video scope system including a video scope in which a solid state image sensor is disposed in a distal end of an insertion to be inserted into an object under inspection and picks up an image of the inside of the object under inspection illuminated by a light fed by a light guide extending in the insertion section, a light source unit having a light source feeding a light into the light guide, and a video processor unit processing a signal supplied from the solid state image sensor to output a picture signal to be displayed on a monitor. The light source unit and the video processor unit are disposed in separate housings, respectively, and these units are connected to each other by a cable to transmit a signal therebetween.
摘要:
An apparatus is disclosed which includes a first and a second optical guides inserted in an elongated insertion portion thereof, and which can transmit an optical image, and an optical system with a function of imaging at the end surface of the optical guide. By transmitting an illuminating light from the other end surface to the portion to be observed through one of the optical guides, the portion to be observed is illuminated. While, the optical image transmitted through the other optical guide is introduced into an ocular system or an imaging system. By changing the functions performed by these optical guides, the stereoscopic observation and stereoscopic imaging can be realized.
摘要:
The invention relates to a method and novel reagents for detecting a ligand in a biological sample. In the method, the sample is combined with (i) an enzyme or an enzyme bound to a first macromolecular compound, (ii) substrate for the enzyme, and (iii) an antibody complex comprising anti-ligand bound to anti-enzyme and a second macromolecular compound bound to either one or both of the anti-ligand and anti-enzyme. The activity of the enzyme varies as a function of the unknown amount of ligand contained in the biological sample.
