Abstract: A socket connector electrically connecting an IC package to a printed circuited board includes a base (3) defining a number of side walls and a receiving region (38), a cover (5) slidably mounted on the receiving region, a lever (6) defining a cam shaft (61) received in the base and an operation handle (62) vertically extending from the cam shaft and a plurality of terminals received in the base. The cover is mounted over the receiving region and enwrapped by the side walls.

Abstract: The present invention provides a method of screening pigs to identify those which have a genetic predisposition to have a thinner or thicker backfat thickness by assaying the pattern of the five single nucleotide polymorphisms in the HSP70.2 gene that is associated with backfat thickness.

Abstract: A thin-film write head employing pole pieces formed of an electroplated body-centered cubic (BCC) nickel-iron alloy with a saturation flux density (BS) of 1.9 to 2.3 T (19 to 23 kG) and an acceptable coercivity (HC) of about 80 to about 160 A/m (1-2 Oe). The iron content of the electroplated nickel-iron alloy is from 64% to 81% by weight. The two-layer pole fabrication process holds magnetic anisotropy and coercivity to useable values while improving saturation flux density and optimizing magnetostriction. This is accomplished by first electroplating a BCC nickel-iron layer onto an underlying seed layer and then annealing the two layers to reduce coercivity to less than about 160 amps/meter and raise magnetization to acceptable levels.

Abstract: An optical disc drive includes a housing, a positioning shaft fixed on the housing, and a tray module. The tray module includes a tray installed inside the housing with the ability to slide, a solenoid fixed on the tray for providing magnetic force, a latch installed beside the solenoid moving in response to changes in magnetic force, a push pod fixed on the tray in a rotatable manner with one end connected to the latch and the other end forming a slot, a hook rotatably fixed on the tray with one end for engaging the positioning shaft and the other end connected to the push pod, a torsion spring fixed on the pivot of the push pod, and a compression spring installed in a track of the housing. One end of the compression spring is fixed in the slot of the push pod.

Abstract: The invention provides a transgenic pig having incorporated into its genome a HSP70 gene or the fragment thereof, whereby said transgenic pig overexpresses HSP70. The transgenic pig of the invention can be used in the production of HSP in large quantity and used as a xenograft source for transplation and an animal model close to human for illustrating the protective roles of HSP. Furthermore, the transgenic pig of the invention has a better meat quality and exhibits an increased growth rate and a reduced backfat thickness.

Abstract: A process for electroplating and annealing thin-films of nickel-iron alloys having from 63% to 81% iron content by weight to produce pole pieces having saturation flux density (BS) in the range from 1.9 to 2.3 T (19 to 23 kG) with acceptable magnetic anisotropy and magnetostriction and a coercivity (HC) no higher than 160 A/m (2 Oe). The desired alloy layer properties, including small crystal size and minimal impurity inclusions, can be produced by including higher relative levels of Fe++ ions in the electroplating bath while holding the bath at a lower temperature while plating from a suitable seed layer. The resulting alloy layer adopts a small crystal size (BCC) without significant inclusion of impurities, which advantageously permits annealing to an acceptable HC while retaining the high BS desired.

Abstract: A shaft roller, including a shaft, a casing with two ends, and further, for each of the two ends of the casing, a bearing support, an end bearing, and a protective cap. The roller further includes a plurality of inner tubes, a plurality of ring holders, and a plurality of inner bearings. For each end of the casing, a groove is cut into the inner periphery of the casing for holding a peripheral outward extension of the bearing support. For each end of the casing, the bearing support has a wheel body with spokes, surrounding the end bearing and holding the end bearing with an inward projection. The end bearing is a needle roller bearing around the shaft, having a needle cage with a plurality of needles. For each end of the casing, the protective cap prevents dust and humidity from entering the casing, being attached to the bearing support by a plurality of blocks.
