Title: Method of purifying exhaust gas from internal combustion engine
Inventor: ITOH TAKASHI
IPC: B01J35/00
Filed: 1995-03-10
Abstract: This method comprises bringing exhaust gas from an internal combustion engine, which is operated at a fuel-lean air/fuel ratio, in contact with an iridium-containing catalyst in a first zone and then in contact with a platinum-containing catalyst in a second zone situated downstream of the first zone. This method is effective for exhaust gas from lean burn engines over a wide temperature range of 200 to 500°C, produces less N2O in a low-temperature range of 200 to 300°C, and can purify exhaust gas stably and effectively even at a high temperature of 700°C or over.

Filed: 1995-09-21
Abstract: A device added to conventional snow shovel/scrapers in the form of an extra handle which will be adjustable in height and length, allowing it to be adjusted to fit the individual user's personal comfort zone.    The invention will consist of a ball and socket type swivel joint placed on the lower of the original shovel/scraper handle. The invention will be fastened by means of nuts and bolts to the original shaft of the shovel/scraper handle between the shovel/scraper blade and the midway point up the original handle in a position comfortable to the individual operating the snow shovel/ scraper.    The ball portion of the ball and socket joint will have a shaft approximately 12" long attached to it, with holes approximately 1" apart at the end opposite the ball, allowing a D-shaped handle grip to be attached by means of nuts and bolts to the shaft at a desired position.    This invention will have a friction type securing device fastened by nuts and bolts approximately 8" up from the point where the ball and socket joint are fastened to the original handle. This friction type holding device will be used to secure the new shovel/scraper handle to that of the original shovel/scraper handle with the D-shaped handle grips of both handles facing the same direction. The securing of the new handle in this position will allow the shovel/ scraper to be stored easily when not in use.     The shovel/scraper will be operated by placing one hand on the original D-shaped hand grip and the other hand on the D-shaped hand grip of the new shovel/scraper handle, then pushing it into the snow and lifting on the new handle and then throwing the snow out of the way.     This additional swivel handle transfers most the muscle power required to shovel snow from the back to the arm holding the new swivel handle.

Abstract: A laminated cylindrical backplane is constructed using disks with a conductive material mounted on a top surface, and a conductive material mounted on a secondsurface. Each disk and its conductive surfaces are separated from adjacent disks and their conductive surfaces by a dielectric material. The laminated structure forms a cylindrical backplane where circuit cards are radially mounted to the backplane by inserting the cards into slots in the perimeter of the cylindrical structure. The slots contain contacts where similarly positioned contacts of a particular disk are electrically connected to form a bus structure. As a result, similarly positioned conductive surfaces on circuit cards are electrically connected when the cards are inserted into the slots.

Abstract: The transfer consists of a backing film (1) which is softened by the effect of a liquid, and a number of layers (2, 3, 4, 5) which are applied to the backing film just before the articles to be decorated are immersed in a bath. At least one of the layers is reticulable, with the reticulation initiated prior to transfer, and the backing layer has a primary layer with reactivatable penetrating inks, and another layer which is an activator for the inks and is applied at the moment the film is immersed. After the article has been immersed and the decoration transferred to it is rinsed to get rid of any backing layer residues and protected by an impermeable film layer. The different layers can be made from composition materials, e.g. containing micro-capsules which are opened before or after application e.g. by laser radiation, electron treatment or thermal shock.
