In a particulate filter, a catalyst layer containing Pt-carried activated alumina particles, CeZr-based mixed oxide particles and ZrNd-based mixed oxide particles is formed, the proportion of the total amount of the CeZr-based mixed oxide particles and the ZrNd-based mixed oxide particles in the total amount of the Pt-carried activated alumina particles, the CeZr-based mixed oxide particles and the ZrNd-based mixed oxide particles is 10% to 60% by mass, both inclusive, and the mass ratio of the CeZr-based mixed oxide particles to the ZrNd-based mixed oxide particles is 20/80 to 80/20, both inclusive. This configuration enhances the particulate burning property and the low-temperature exhaust gas conversion efficiency.

According to an aspect of an embodiment, a memory controller for writing data into and reading data from a memory, comprises an error detector for detecting an error of data stored in the memory when reading the data, a time stamper for generating first time information indicative of the time when data is written into the memory, the first time information being written together with the data into an address location of the memory where the error has been detected, a timer for measuring a time period from the time indicated by the first time information until the time of subsequent occurrence of an error of data stored in said address location and a counter for counting a number of accesses to the address location over the time period.
摘要:
An ultrasonic receiver receives an ultrasonic signal having a period in which an amplitude thereof progressively increases as time elapses. A pattern matching unit determines whether a comparative pattern, which is generated as a result of comparison between the respective maximum amplitude values of a plurality of successive waves of said wave signal and a threshold value set by a threshold setting unit, matches a reference pattern or not during the period of the ultrasonic signal. The pattern matching unit determines that the ultrasonic receiver has successfully received the ultrasonic signal if the comparative pattern matches the reference pattern.

Disclosed is a particulate filter, which is adapted to be disposed in an exhaust passage of an engine to trap particulate matter contained in exhaust gas discharged from the engine. The particulate filter comprises a filter body having a porous partition wall which defines a plurality of exhaust gas channels allowing the exhaust gas to pass therethrough, and a catalyst layer formed on a surface of the porous partition wall. The catalyst layer includes a Zr-based composite oxide which contains zirconium (Zr), and a rare-earth metal except cerium, wherein a content ratio of an oxide of the non-cerium rare-earth metal to a total amount of ZrO2 and the oxide of the non-cerium rare-earth metal in the Zr-based composite oxide is set in the range of greater than 33 mol % to less than 40 mol %. The particulate filter of the present invention can achieve a higher PM burning rate to burn PM within a shorter period of time. In addition, the higher PM burning rate makes it possible to provide enhanced fuel economy performance in an engine designed to perform a post-injection control.
摘要:
A method for performing a vapor deposition process is described. The vapor deposition process involves the deposition of a thin film, such as a ruthenium (Ru), rhenium (Re) or rhodium (Rh) film, on a substrate using a solid-phase or liquid-phase precursor. The method facilitates the initiation of gas lines to supply dilution gas(es), carrier gas(es) and precursor vapor to the deposition system, the pre-heating and heating of the substrate, the pre-conditioning of the film precursor vaporization system, and the flow stabilization of the carrier gas(es) and the precursor vapor, for example.
摘要:
A method for introducing a precursor vapor to a process chamber configured for forming a thin film on a substrate is described. The method includes transporting a process gas containing metal precursor vapor and a CO delivery gas to a process chamber, and introducing a CO saturation gas to the precursor vapor in the process chamber and optionally adjusting the spatial distribution of the CO saturation gas addition in order to affect improvements to the properties of the deposited film.
摘要:
A high conductance, multi-tray film precursor evaporation system coupled with a high conductance vapor delivery system is described for increasing deposition rate by increasing exposed surface area of film precursor. The multi-tray film precursor evaporation system includes one or more trays. Each tray is configured to support and retain a solid precursor, and permit the flow of a carrier gas. Furthermore, each tray comprises precursor stabilization elements designed to maintain a substantially level solid precursor powder during transport of the multi-tray precursor evaporation system.
