摘要： A vehicle wheel bearing apparatus which reduces the weight, size and number of parts and also prevents ingress of rain water or dusts and leakage of differential gear oil has an axle housing supported under a body of a vehicle. A hollow drive shaft is inserted into the axle housing. A wheel bearing is arranged between the drive shaft and an opening of the axle housing and is structured as a unit including a wheel hub and a double row rolling bearing. The wheel bearing includes an inner member with a wheel hub integrally formed with a wheel mounting flange on one end and an axially extending cylindrical portion. At least one inner ring is press-fit onto the cylindrical portion of the wheel hub. The inner ring is formed with at least one of the inner raceway surfaces on its outer circumferential surface. An outer member is arranged around the inner member and formed with double row outer raceway surfaces on its inner circumferential surface opposite to the inner raceway surfaces. Double row rolling elements are arranged between the inner and outer raceway surfaces of the inner member and the outer member. A cage freely rollably holds the rolling elements. Seals seal an annular space between the inner member and the outer member. A cap, having a metal core formed from steel, is press-fit into an end of a central bore of the wheel hub.

摘要： To provide a third generation type wheel support bearing assembly in which a stress concentration in a recess in a hub axle can be reduced, and the repeated fatigue strength can be increased. A hardened layer is provided by means of a heat treatment at least in a portion from a raceway in a surface portion of a hub axle made of a carbon steel to a flange root portion. A recess as a circumferential groove is formed along a corner portion defined between a raceway in the hardened layer and a large collar with which an end face of a roller contacts. The recess is formed by means of a lathe turning work, after formation of the hardened layer and then undergoes machining or grinding within an inner surface thereof, thereby causing a compressive residue stress to the hardened layer.

摘要： A wheel bearing apparatus has an outer member, an inner member, at least one inner ring fit onto the inner member. Double row rolling elements are rollably arranged between the outer and inner raceway surfaces, via cages. A seal is mounted on one end of the outer member. The seal has side lips adapted to be in sliding contact with the wheel hub. The seal has three inclined side lips each extending radially outward from the seal body. The lips are adapted to be in sliding contact with the base of the wheel mounting flange. Interference of the side lips against the base of the wheel mounting flange is set so that the radially inner side lip has a smaller interference than that of the radially outer side lips, in order.

摘要： A transmission is provided in which gears (31 to 34) of a first gear group provided on a first auxiliary input shaft (13) to which driving force of a main input shaft (12) is transmitted via a first clutch (24) and gears (37 to 39) of a second gear group provided on a second auxiliary input shaft (14) to which the driving force of the main input shaft (12) is transmitted via an idle gear (17 to 19) and a second clutch (25) use in common gears (43 to 46) of a third gear group provided on an output shaft (16), whereby it becomes possible to cut the number of components and reduce the dimensions of the transmission. Further, since the advance/retard relationship between the timing with which the first and second clutches (24, 25) are switched over and the timing with which the synchronizing devices (35, 36, 41, 42) are switched over can be freely chosen when establishing any of the gear positions, it is possible to prevent the occurrence of shift shock due to timing lag, thus enabling gear shifting to be carried out smoothly.

摘要： The present invention introduces methods, systems, and architectures for routing clock signals in an integrated circuit layout. The introduced clock signal clock signal structures are rendered with non Manhattan routing. In a first embodiment, the traditional recursive H clock signal structure is rendered after transforming the coordinates system such that a rotated recursive H clock signal structure is rendered. In another embodiment, a recursive Y structure is used to create a clock signal structure. The recursive Y structure may also be implemented in a rotated alignment. For clock signal redundancy, non Manhattan wiring may be used to create a clock signal mesh network.

摘要： In the field of semiconductor production using charged particle beam lithography, a method and system for fracturing or mask data preparation or proximity effect correction is disclosed. Base dosages for a plurality of exposure passes are set and a multiplicity of shots for the plurality of exposure passes is exposed. The multiplicity of shots comprises two groups: a first group of shots for at least two exposures passes, wherein the union of shots for each exposure pass covers the same area, and where shots within an exposure pass are disjoint; and a second group of shots, where each shot in the second group of shots overlaps a shot in the first group of shots. Each shot in the second group is in one of the plurality of exposure passes. A method for forming a set of patterns on a surface is also disclosed.
