摘要: An exhaust gas purifying system for a diesel engine has an ECU, a passage of exhaust gas, a unit having SCR catalyst, a NOx sensor placed at a downstream side of the unit, and a urea water adding valve placed at an upstream side of the unit. The SCR catalyst in the unit selectively adsorbs ammonia, and selectively purifies NOx contained in an exhaust gas emitted from the diesel engine by the adsorbed ammonia. The ECU changes the urea water adding amount, and performs abnormality diagnosis based on the detection result of the NOx sensor while changing an adding amount of the urea water. The ECU uses a first condition to indicate the presence of an excess NOx amount in the exhaust gas, and a second condition to indicate there is no error cause by the ammonia adsorption on the SCR catalyst.

摘要: An exhaust emission control device reduces nitrogen oxide in exhaust air from an engine. The device includes an exhaust pipe, a catalyst, a supply device, a NOx detecting device, and a control device. The pipe defines a passage for the exhaust air. The catalyst is disposed in the pipe and promotes reduction reaction of the nitrogen oxide. The supply device supplies an additive agent, which is used for the reaction, to an upstream side of the catalyst in the exhaust air flow direction. The detecting device detects the nitrogen oxide included in the exhaust airs which has passed through the catalyst. The control device controls the supply device. The control device determines a deterioration state of the catalyst based on a result detected by the detecting device and reduces an amount of the additive agent, which is supplied, according to the determined deterioration state.

摘要: An improved rotation angle detecting device that detects a rotation angle of a first member relative to a second member is proposed. The rotation angle detecting device includes a magnet unit fixed to the first member and a pair of magnetic sensors fixed to the second member to provide output signals whose phase is different from each other at 90 degrees in angle. The magnet unit includes a pair of disk plates that has the same magnetic poles at the same circumferential positions and is disposed at a prescribed axial distance and a shaft that is made of magnetic material to support the disk plates at the center thereof. The magnetic unit provides a uniform magnetic field in a space around the shaft between the pair of disk plates, and a pair of magnetic sensors is disposed in the space.

摘要: A document management system can access a necessary document fast when necessary and accurately limit access in accordance with various security levels. An access control list shown in FIG. 2 mainly functions when access to a document is limited. One row in the access control list includes a plurality of fields which are described at the head row of each column. Information in each field included in one row (record) indicates the overall information necessary for setting predefined access control to the document including one character string. A “character string” field means that the document including the character string described in the field, of many documents stored in a database, is a document to which the access is limited.

摘要: A turbine wheel of a turbocharger has a turbine blade. The turbine blade has a fin shape of which width in the rotation direction of the turbocharger is narrow, and is projected from the base portion of the turbine wheel. An inclined part of the turbine blade is inclined with respect to the rotation direction of the turbocharger. A coil is disposed so that the inclined part passes nearby as the turbine wheel rotates in a posture that an end in the center axis direction is directed toward the turbocharger. A detector detects a change in inductance, which occurs when the inclined part of the coil passes nearby.

摘要: An SCR catalyst is provided in an exhaust pipe of an engine and a urea solution addition valve is provided upstream of the SCR catalyst in the exhaust pipe. An ECU calculates ammonia adsorption quantity of the SCR catalyst and controls urea solution addition quantity, which is added by the urea solution addition valve, based on the ammonia adsorption quantity. The ECU obtains temperature of the SCR catalyst or temperature information correlated with the temperature through measurement or estimation. The ECU switches an execution mode of the urea solution addition control based on the catalyst temperature or the temperature information. Thus, reducing agent addition control can be performed suitably and eventually NOx purification in a NOx catalyst (i.e., SCR catalyst) can be performed suitably.
