  • Patent number: 7894558
    Abstract: A receiver circuit controls a power source of a front-end circuit and a demodulator using a first power source control signal. Upon receiving data of a plurality of receiving slots having a guard bit provided between receiving slots adjacent to each other, the first power source control signal becomes a power source ON signal before starting receiving of the data, then becomes a power source OFF signal within the guard bit, and becomes a power source OFF signal after completing the receiving of the data. The receiver circuit controls a power source of an active filter circuit using a second power source control signal, which becomes a power source OFF signal after completing the receiving of the data after becoming a power source ON signal before starting the receiving of the data.

  • Patent number: 7048894
    Abstract: A catalyst-loaded ceramic filter made of a ceramic material capable of directly supporting a catalyst component thereon is capable of providing early activation of the catalyst with a low coefficient of thermal expansion and light weight, without compromising the high porosity of the filter substrate. A catalyst-loaded ceramic filter is made of a ceramic material of which one or more kinds of element among its constituent elements is substituted with an element other than the constituent elements, for example a ceramic material with a part of Si or other elements included in cordierite is substituted with W or Co, as a filter substrate of honeycomb structure having a number of cells separated by porous walls, and supporting a catalyst such as a noble metal directly on the W.

  • Patent number: 6863705
    Abstract: A ceramic material containing organic binder is formed by extrusion, dried and cut off so as to make the honeycomb body 100 having the bulkheads 11 and a plurality of cells 12 partitioned by the bulkheads 11 and penetrating between both end faces of the honeycomb body 100. The tapered jig 3 having a tapered forward end portion 31 is inserted into the opening 13 of the cell 12 of the honeycomb body 100. Then, the bulkheads 11 are heated and softened and deformed by a pushing force given by the tapered jig 3 so that the opening 13 of the cell 12 is expanded to form the large opening 131, and the opening 13 of the adjoining cell 12 is reduced at the same time so as to form the small opening 132. After that, the honeycomb body 100 is fired. In this way, the exhaust gas purifying filter for collecting particulates is manufactured.

  • Patent number: 6790248
    Abstract: An exhaust gas filter is capable of suppressing the generation of an excessive pressure loss due to the particulates deposited. At least a part of a multiplicity of cells surrounded by partitioning walls of the honeycombed exhaust gas purification filter have plugs on one of their two end portions. At least a part of the cells to be arranged on the downstream side in the fluid path are partial plugs having openings allowing the fluid flow. The pressure loss caused when the fluid entering the cells passes through the partitioning walls is smaller than the pressure loss caused when the exhaust gas passes through the partial plugs.
