摘要:
Disclosed is a catalytic filter for removing soot particulates from diesel engine exhaust, which is comprised of monolithic oxidation catalyst upstream of the catalytic filter, which effectively oxidize gaseous pollutants and volatile organic fractions, and a catalyzed wall-flow filter downstream serving to low temperature combustion of soot particulates collected on the filter. Also, the preparation method of the catalytic filter is provided, including the colloidal mixture solution of platinum group metal salts and other metal salts with a water-soluble polymer and a reducing agent, which is then impregnated on a catalyst support, followed by calcining at high temperatures. In the present invention, use of the catalytic filter provides effective means of abating diesel exhaust pollutant emissions, that is, particulate matter (PM) and gaseous pollutants (HC, CO, NOx).

A payment receipt system is provided. The payment receipt system comprises: a receipt management database for managing at least information on the payers who have to pay and the payment amount that the respective payers have to pay for a certain period; and a payee server including an information extracting part for extracting information including the information on the payers and the payment amount from the receipt management database, a code converting part for converting the extracted information into a two-dimensional (2D) code, a bill forming part for making out a bill for payment with the converted 2D code attached thereto, a bill transmitting part for transmitting the bill for payment to a receiver of the payer, and a controller receiving information on the payers who have completed a payment from a financial institution server.
摘要:
In accordance with one or more embodiments of the present disclosure, a display assembly received in a cover by the front mounting method, a combining recess is formed on a corner formed at which a side part and an upper portion of a supporting part meet together, and a first hole is formed on a bottom of the combining recess. A first opening exposing the first hole is formed in a top surface part of a front receiving frame. A bottom part of a rear receiving frame supporting a rear face of a display module has a second hole corresponding to the first hole. An incision portion opening the sidewall part of the rear receiving frame exposes the second hole, the first reinforcement member is bent around an edge of the sidewall part, and connects the opposite edges. As such, the width of a frame of the cover is reduced, and the rear receiving frame improves the strength against external force.
