  • Patent number: 7144560
    Abstract: Each of vertical frame members which constitute a frame body of a high-temperature denitration apparatus and which are erected in a spaced-apart relationship in a direction of exhaust gas flow is provided by a pillar member. The pillar member is an integral combination of a web with upstream and downstream flanges so as to improve thermal conductivity of the same. The web of the pillar member is formed with openings for suppression of thermal capacity to a minimum so as to reduce in weight the web and enhance a temperature rising velocity of the web.

  • Patent number: 6857414
    Abstract: There is provided a control system for an internal combustion engine, which is capable of matching an output torque of the engine with a demanded torque excellently when the combustion mode is switched, thereby enhancing drivability. A demanded fuel amount and a demanded torque of the engine are calculated according to detected operating conditions of the engine. A combustion mode is determined to be either the stratified combustion mode or the homogeneous combustion mode according to the demanded torque. A pre-switching demanded fuel injection time period and a pre-switching demanded torque are stored. When the combustion mode is switched, a switching-time demanded fuel amount (limit value) is calculated according to the stored pre-switching demanded fuel injection time period and pre-switching demanded torque, the current demanded torque, and an estimated combustion efficiency parameter.

  • Publication number: 20040222826
    Abstract: A data form converter allowing parallel-to-serial or serial-to-parallel conversion at various conversion ratios is disclosed. A frequency divider divides an input clock in frequency at a variable frequency division ratio to produce a single frequency-divided clock. A data shift circuit shifts serial input data according to the input clock to output n-bit parallel data, where n is determined depending on the variable frequency division ratio. A retiring section synchronizes the n-bit parallel data with the single frequency-divided clock to output parallel output data.

  • Publication number: 20040009874
    Abstract: A plurality of shell frame panels are assembled into a box-shaped unit with front and rear open ends. Each of the shell frame panels has a picture-frame-like shell frame and shell plates mounted to the shell frame so as to be slidable upon thermal expansion. Catalysts are charged in the box-shaped unit and supported by the shell frames. In use, the shell plates low in thermal capacity rapidly rise in temperature and try to expand. The box-shaped unit is adapted such that such expansion of the shell plates is not blocked by the shell frames higher in thermal capacity then the shell plates. As a result, no bucking of the shell plates occurs and the catalysts are prevented from being broken.

  • Publication number: 20030234497
    Abstract: Seal plates are mounted to and extend from a rim of a frame body to an inner surface of a casing so as to prevent short pass of exhaust gas. Seal guides are mounted via heat shield bases on the inner surface of the casing to receive the seal plates such that the seal plates are slidable upon thermal expansion of the frame body. Heat of hot exhaust gas passing through the casing and trying to propagating via the seal guides to the casing is shielded by the heat shield bases. As a result, no hot spots are produced on portions of the casing where the seal guides are mounted.
