A card reader is provided inside of a body cover which has a card transfer path, a card transfer mechanism including a series of card transfer rollers and driven rollers, and a second antenna unit defining a wireless communication device which is positioned between the card transfer path and the body cover (,). Thus, wireless transmission and reception of data can be executed with the second antenna unit by bringing a card having a first antenna unit in close proximity to a card access area provided on the body cover, and also by inserting the card in the card transfer path.

In a purifier for removing particulates from an exhaust gas, a pressure difference, and a flow rate of the air supplied to the filter element is adjusted in such a manner that a difference between a pressure difference of an air across a substantially invariable air flow resistance before the air reaches a filter element collecting and storing the particulates therein and a reference pressure difference is a predetermined value, while heating the air.

Exhaust gas purifier and regeneration method therefor

An exhaust gas purifying method, an exhaust gas filter and an exhaust gas filter purifying apparatus reduce the quantity of collected particulates on the outer periphery of the exhaust gas filter and prevent insufficient combustion of particulates during regeneration. The exhaust gas purifying method purifies an exhaust gas by using an exhaust gas filter including a throughhole diaphragm formed into a honey-comb shape in an outer peripheral wall integrally with this outer peripheral wall. A sealing portion is formed on an end portion of a plurality of throughholes partitioned by the throughhole diaphragm, so that the quantity of particulates collected in the throughholes adjacent to the outer peripheral wall and the throughhole diaphragm is reduced as compared with the other portions. The exhaust gas filter has a second sealing portion formed in the throughholes adjacent to the outer peripheral wall and the sealing portion on one end surface of the exhaust gas filter.

Exhaust as purifying method, exhaust gas filter, and exhaust gas filter

The amount of generation of heat per unit time due to combustion reaction of particulate matter is suppressed, and is made lower than the amount of heat radiation per unit time. By doing so, an abrupt temperature rise called 'ignition' is prevented, and a temperature gradient in a filter is made small, thereby preventing unduly-high temperatures from developing. Therefore, the cracking of the filter as well as damage of the filter due to melting can be perfectly prevented, thereby enhancing the reliability. To achieve this, the whole of the filter is heated in such a manner that a temperature rise rate is not more than 10.degree. C./minute when the temperature in the filter is in the range of between 400.degree. C. and 600.degree. C. In the case where the filter carries an oxidizing catalyst, the heating is effected in such a manner that the temperature rise rate is not more than 10.degree. C./minute in the range of between 200.degree. C. and 400.degree. C.
