Abstract: During a predetermined operation state in which the opening degree of a throttle valve is fixed, an air flow meter positioned more on the upstream side than a pressure control valve detects a first intake air amount when the opening degree of the pressure control valve positioned on the upstream side of the throttle valve is set to a predetermined first valve opening degree and a second intake air amount when the opening degree of the pressure control valve is set to a predetermined second valve opening degree smaller than the first valve opening degree. On the basis of the first intake air amount and the second intake air amount, a diagnosis is made regarding whether there is an abnormality in a first pipe, a second pipe, a third pipe and the like which are included in a blow-by gas recirculation system for blow-by gas treatment.

Abstract: A mobile node is arranged to perform a high-quality hand-over operation for eliminating an interruption time in communication and keeping the continuance of communication excellent. The mobile node has a function of interfacing with networks and includes a network quality monitor, a hand-over controller, and a network controller. The network quality monitor operates to monitor a network quality based on at least one of an intensity and a radio bandwidth of a radio wave received by network devices. The hand-over controller performs the hand-over operation of transmitting a care of address to an address registering destination in response to a state of the network quality before a communication is disconnected, changing a route of communication information, and switching a connecting destination into a new network.

Abstract: A meter device includes a dial having a display design, a case which is disposed on one side of the dial, and supports the dial, a substrate which is disposed on a side of the case opposite to the dial, the substrate being provided with an electric component for display driving of the dial, a plurality of engagement claws each of which is raised toward the substrate from an outer circumferential portion of the case, and is formed to be elastically deformable in inward and outward sides of the case, and a claw part which projects in an inward direction of the case from a leading end part of the engagement claw, and has an engaging face engaging with an outer circumferential edge portion of the substrate from a side of the substrate opposite to the case side, so as to fasten the substrate to the case.

Abstract: The present invention provides a digital camera and an image data processing system, which can develop and observe images recorded by both a compressed image recording control function and a raw image recording function on an external image processing device regardless of the presence/absence of a raw image reproducing function. When an image of CCD-raw data is reproduced on a PC, a self-development execution module is added to an image file to make it possible to perform reproduction such as display of the data on the monitor of the PC without arranging a dedicated viewer for reproducing CCD-raw data on the PC.

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.

Abstract: A structure for a circuit board attaching portion includes a circuit board on which an engaged portion are formed and a mounting part in which an engaging claw are formed. The circuit board is attached to the mounting part by engaging the engaging claw with the engaged portion. A catch preventing portion, which prevents the engaging claw from being caught, is formed on the engaged portion. Even when an edge portion of the engaged portion has an acute angle or even when there is a difference in hardness between the circuit board and the mounting part, the catch preventing portion effectively prevents a catch between the engaged portion and the engagement claw from occurring. Therefore, the efficiency of the attaching work can be improved and the circuit board can be prevented from cracking.

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.

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.
