摘要:
An electrically heating catalytic apparatus that quickly heats catalyst to an activation temperature even when the engine is started at a low temperature below the catalyst activation temperature. The apparatus employs an electrically conductive catalyst carrier that is electrically heated. The carrier is provided with local hot spots to be energized. Since the heat is locally generated, the heat capacity of the catalyst carrier is small to shorten a temperature increasing time.

摘要:
A bent portion (adsorption box) is formed in part of an exhaust pipe connecting exhaust ports and a catalyst for purifying HC or the like in the exhaust gas, and a HC adsorbent of a honeycomb structure is placed forward with respect to the direction in which the exhaust gas travels straight without turning at the bent portion. The exhaust gas flowing from the exhaust ports, turns, and flows into the exhaust pipe, but HC having a large particle size travels straight along rectifier blades to be adsorbed by the HC adsorbent and held for a while. During such process, the catalyst connected to the exhaust pipe is heated up to be activated, thereby for purifying the HC or the like which is desorbed by the temperature rise of the adsorbent. Another HC catalyst may be carried in the front of the adsorbent that is easily heated to a high temperature, or an EGR passage including an EGR control valve may be connected downstream from the adsorbent.
摘要:
An internal combustion engine in which a three-way catalyst (12) for purification of the exhaust gas is arranged in the exhaust passage, wherein the relationship between the magnitude of the stress causing deterioration of the three-way catalyst (12), for example the catalytic bed temperature, and the rate of deterioration of the performance of the catalyst is found. A durability test is performed by raising the catalytic bed temperature higher than that of the vehicle under market driving. The length of the durability test at this time is determined from the relationship between the catalytic bed temperature and the rate of deterioration of the performance of the catalyst so as to give the same degree of deterioration of the performance of the catalyst as with market driving. The length of the durability test required for giving the same degree of deterioration of the performance of the catalyst is much shorter than the market driving time.
摘要:
An engine comprising an exhaust passage having therein a NO.sub.x absorbent which absorbs the NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent is lean and releases the absorbed NO.sub.x when the concentration of oxygen in the exhaust gas is lowered. When the air-fuel ratio of air-fuel mixture fed into the engine cylinder is made a rich air-fuel ratio or the stoichiometric air-fuel ratio, a secondary air is fed into the exhaust passage upstream of the NO.sub.x absorbent to make the air-fuel ratio of exhaust gas lean.

An HC-adsorbent capable of adsorbing various kinds of hydrocarbon including lower and higher hydrocarbon, of which the adsorbable amount per unit volume is large, and which exhibits excellent durability at elevated temperatures. The HC-adsorbent is composed of a first zeolite of ZSM-5 of which the silica/alumina (SiO.sub.2 /Al.sub.2 O.sub.3) mole-ratio is 500 or more, and a second zeolite of Y-type zeolite of which the silica/alumina (SiO.sub.2 /Al.sub.2 O.sub.3) mole-ratio is 200 or more. The second zeolite mainly adsorbs higher hydrocarbon while the first zeolite mainly adsorbs lower hydrocarbon, thus enabling adsorption of many kinds of hydrocarbon.

摘要:
To enable power saving control by putting storage areas of the same attribute together in a specific RAID group in a storage apparatus that includes storage areas of different access patterns.The storage apparatus manages attributes of the RAID groups, which form a pool area, and attributes of the respective storage areas, based on an access log for each of the storage areas allocated to virtual volumes. The apparatus enables a power saving operation for each RAID group by putting the storage areas of each attribute together in a specific RAID group.

A data transfer device that confirms completion of writing into a memory on transferring data to the memory via a bus through which a response indicating completion of data writing in the memory is not sent back includes an inter-memory data transfer control unit performing data transfer between the memories. When the inter-memory data transfer control unit detects switching of a write destination memory from a first memory to a second memory, in order to confirm that writing into the first memory is completed, the inter-memory data transfer control unit performs confirmation of write completion as to the first memory by a procedure different from writing into the memory. When a data transfer with a designated transfer length is completed, in order to confirm that writing is completed as to the write destination memory at the end of the data transfer, the inter-memory data transfer control unit performs confirmation of write completion as to the write destination memory at the end of the transfer by the procedure different from writing into the memory. The inter-memory data transfer control unit notifies the processor of completion of an inter-memory data transfer based on the confirmation of write completion.
摘要:
A microchip 1 in which a resinous film can be inhibited from sagging into a channel. The microchip 1 comprises: a resinous substrate 2 having a channel groove formed therein; and a resinous film bonded to a surface of the substrate on which the channel groove has been formed. A micro-channel 3 including channels 3A and channels 3B is formed by the channel groove and the resinous film 10. The total length of the channels 3B, which is parallel to the X direction for the resinous substrate 2, is larger than the total length of the channels 3A, which is parallel to the Y direction for the resinous substrate 2. The resinous substrate 2 has been bonded to the resinous film so that the sides parallel to the channels 3B are parallel to the TD direction of the resinous film and that the sides parallel to the channels 3A are parallel to the MD direction of the resinous film.
