    摘要: A multiprocessor system having a redundant shared memory configuration includes a plurality of processors, each of which are connected to a shared system bus; and a plurality of shared system memory modules, e.g., dual shared system memory modules connected to the shared system bus. A first processor module is operative to write data in one of dual shared system memory modules and subsequently write the data in the other memory module, so as to ensure that the data in both dual shared system memory modules are equivalent to each other. A second processor module monitors a status of the first processor module, and discriminates whether a write operation for the other memory module is finished in normal termination or in abnormal termination in the case where the first processor module stopped operating. The second processor module copies data starting from the address of a first data in the unsuccessfully copied data from the first memory module to the second memory module.

    摘要: An apparatus for purifying an exhaust gas emitted from an internal combustion engine, particularly, immediately after starting of the engine, includes a mechanism for reducing the time required to heat a catalyst converter to the activation temperature. The exhaust gas is passed through a preliminary catalyst close to the engine and then through a main catalyst downstream of the catalyst. The engine is operated with an air-fuel mixture which is richer than the amount indicated by the stoichiometric air/fuel ratio for a period of time from when engine is started until the main catalyst is heated to a temperature at which the catalyst can sufficiently perform its purifying capability. The preliminary catalyst is enabled to function at lower temperatures by combusting the exhaust gas which is generated during a rich air-fuel mixture condition. The main catalyst can be heated with the generated combustion heat, resulting in an enhancement in exhaust gas purifying capability.

    摘要: A multi-gated pulsed wave color Doppler imaging system is used to provide accurate non-invasive measurements of liquid flow through a narrowed orifice by using the color Doppler to first measure the velocity of flow along an axis perpendicular to the orifice to provide a first image of the liquid velocity. The first image includes a two-color interface at locations in the image representing locations where the liquid velocity is equal to the aliasing velocity of the color Doppler imaging system. The distance from the two-color interface to the center of the orifice is measured and saved. A second image is obtained along an axis perpendicular to the first axis to represent the flow of liquid to the orifice from the perimeter of the orifice. The distance from a two-color interface to the center of the orifice in the second image is measured. The two measured dimensions are used to model a hemi-ellipsoidal surface proximal to the orifice wherein all points on the surface have the same isovelocity. The surface area is multiplied by the aliasing velocity to obtain the volume fluid flow rate through the orifice. A third image can also be obtained along a third axis perpendicular to the first and second axes and used to model an alternative hemi-ellipsoidal isovelocity surface. In a further alternative, a single image can be used to model a panshaped isovelocity surface.

    摘要: Disclosed herein is a piezoelectric displacement element utilizing a sintered body obtained by stacking three or more ceramic layers (5a to 5h) through internal electrodes (6b to 6h) and co-firing the same. The sintered body has first, second and third regions when viewed in the direction of thickness. The first and third regions are so formed as to be displaced in reverse directions to each other. The second region consists of a plurality of piezoelectric ceramic layers (5d, 5e) in such a manner that an internal electrode (6e) interposed between the piezoelectric ceramic layers (5d, 5e) is connected with neither potentials in a driven state, whereby the second region is adapted not to be positively driven, to function as a buffer area.
