Abstract: A data transfer device for preventing a PCI-X bus from hanging up, which can be caused when a sender of data aborts. An abort signal-receiving section receives an abort signal delivered by the sender of data when the sender aborts. When the abort signal-receiving section receives the abort signal, a dummy data-generating section generates dummy data. When the abort signal-receiving section receives the abort signal, an erroneous parity data-generating section generates erroneous parity data for indicating that the dummy data generated by the dummy data-generating section is a dummy. A data-transmitting section transmits the dummy data generated by the dummy data-generating section and the erroneous parity data generated by the erroneous parity data-generating section, to a recipient of the data via the PCI-X bus.

Abstract: An expansion/compression mechanism of a piston rod assembly is composed of a bush shaft, a first cylindrical piston rod that is screwed with the bush shaft, a second cylindrical piston rod that is screwed with the first piston rod, and a piston rod holding member for housing the bush shaft and the piston rods. Therefore, the piston rods move linearly in multiple stages, whereby the size of the whole apparatus is reduced.

Abstract: The fixed layers of all magnetoresistive elements that are formed on the same substrate are magnetized in the same direction. Chips including magnetoresistive elements are cut out individually from the substrate. A magnetic sensor is assembled by combining cut-out chips together with consideration given to the magnetization directions of the fixed layers of the magnetoresistive elements in the chips. In this manner, the fixed layers of the magnetoresistive elements are magnetized by a sufficiently strong magnetic field for magnetization, whereby an output signal having a large absolute value is obtained from the magnetoresistive elements.

Abstract: A magnetic switch using magnetoresistive elements having respective free layers whose magnetization directions are varied by an external magnetic field. The magnetic switch also has a first magnet and a second magnet that produce respective magnetic fields that serve as the external magnetic field and are different from each other in strength and opposite to each other in direction, and a magnetic shield member whose relative position with respect to the first magnet and the second magnet varies. The magnetic shield member moves between a first position with which both of the magnetic fields of the first magnet and the second magnet act on the magnetoresistive elements to magnetize their free layers in a first direction and a second position with which only one of the magnetic fields of the first magnet and the second magnet acts on the magnetoresistive elements to magnetize their free layers in a second direction that is opposite to the first direction.

Abstract: There is provided an exhaust emission purifying catalyst device which is comprised of a carrier disposed in an exhaust passage and including through holes passed through the carrier in an axial direction (flowing direction), and supporting layers made of fire-resistance inorganic oxide formed on inner surfaces of the through holes. The supporting layers support noble metal and NOx trapping agents which occlude NOx in exhaust gas when the exhaust air-fuel ratio is lean, and emits and reduces the occluded NOx when the exhaust air-fuel ratio is stoichiometric or rich. The amount of the supported noble metal is set to be smaller in an exhaust passage upstream area of the carrier than in an exhaust passage downstream area of the carrier.

Abstract: The present invention has an object of providing a rational connection configuration for an inner rotor type stator comprising coil windings provided for each pole blade. Accordingly, the connection configuration of the invention comprises three types of electric conductors corresponding to U-, V- and W-phases, respectively, and shaped like a ring. Each electric conductor has a projection extended in four directions corresponding to four groups of coil windings each of a same phase, and a lead representing each phase and extending outward of an outer diameter of the stator. The electric conductors and a common electric conductor are arranged on an end plate concentrically. Connections between the coil windings and the projections respectively of the same phase are radially arranged at places outward of the grooves of the end plate as to effect connection therebetween.

Abstract: In a stator for an electric motor, insulating members are formed on laminated iron cores divided for each pole-tooth unit in the direction of the output shaft and windings are applied perpendicularly to the pole-tooth portions in a high-density alignment. After a predetermined number of the laminated iron cores are combined so as to form a cylindrical configuration, they are welded at the outer end portions of the dividing surfaces in the direction of lamination so as to construct an integral structure stator with rigidity, thereby enabling high densification of the windings (conductor space factor of 70%) and space-savings in the winding end portions. Further, as any joint portions between the pole-tooth portions are not necessary, reduction (5 to 10%) in motor efficiency due to such joint portions can be prevented, and, as any integrally forming by resinous members is not necessary, inter-winding short-circuiting is not caused. Welding may be replaced by adhesive bonding.
