A land grid array connector (100) has a stiffener defining a window (305) thereon, a metal clip (40) pivotably coupling with stiffener, a lever (50) engaging on the stiffener, a housing (10) received in the window of the stiffener and a number of contacts mounted to the housing. The lever includes a pair of locating portions (501) and an offset actuating portion (503) disposed between the locating portions. The clip includes a projecting portion (400) having a depress portion (405) for receiving the offset actuating portion of the lever, a protruding portion (406) bending upwardly and inwardly from an end of the depress portion and a pair of guiding portions (4060) extending outwardly from the protruding portion for resisting against opposite ends of the offset actuating portion.

A ZIF socket connector comprises a base defining a plurality of passageway therein and each received therein a contact terminal therein. The base defines a first and second end. A cover is moveably attached to the base in a direction from the first end to the second end of the base, and defines a plurality of guiding holes each aligned with the passageway. An actuating lever with a cam portion is disposed in the first end of the housing, and is interengaged with the cover so as to move the cover on the base along the direction. The cover includes a top surface. A pick up cap is disposed on the top surface of the cover, and includes a first end disposed on the top surface of the cover, and a second end interlocked to a sidewall of the base at the second end. The first end of the pickup cap is released when the cover is moved away from the second end of the base.

Provided herewith a land grid array socket comprises an insulative housing having a plurality of contacts. The insulative housing has a top surface for receiving a land grid array package. A cover member is pivotally mounted on a first end of the insulative housing. The cover member is pivotal between an open position and a closed position where the cover member presses the land grid array package toward the top surface of the insulative housing so that the land grid array package electrically connects to the contacts. A lever is pivotally mounted on a second end of the insulative housing and has a tilted shaft portion biasing against the second end thereof so as to create a self-biasing force with respect to the reinforce plate

The present invention provides a method and a system for improving the precision of element measurement based on laser-induced breakdown spectroscopy. The method comprises: press-forming a sample to be measured with a tablet press; making a hole on or immediately above a surface of the press formed sample; forming a layer of aerosol immediately above the surface of the sample to be measured with the components thereof completely identical to those of the sample to be measured; testing the sample to be measured by using a laser-induced breakdown spectroscopic system, so as to obtain the intensities of the characteristic spectral lines of a target element in the sample to be measured; and determining the concentration of the target element in the sample to be measured according to a calibration curve of the target element in prearranged calibration samples.

Method and apparatus for reducing residual torque in singles ring yarns, achieved by imparting two separate false twisting points on the traveling strand of fibers (or yarn) after the strand exits from the spinning triangle with a proper ratio between the belt speed and the strand feeding speed. In addition to reducing the residual torque, this double false twist technique also reduces yarn hairiness to the same level as achieved by more expensive compact spinning devices, reduces yarn twist by more than 20% and significantly enhances yarn and fabric softness. Furthermore, by combining the double false twist technique with a compact spinning device, the numbers of neps, thick and thin places are significantly reduced to produce high-quality yarns and fine-count yarns.

An electrical contact terminal used for an electrical connector, includes a planar vertical base portion (20) having a front main face and a pair of lateral side edges, a solder portion (21) extending downwardly from the base portion, a U-shaped resilient arm (29) connecting to one lateral side edge of the base portion. The U-shaped resilient arm has a pair of contact portions defining therebetween a slot extending along a direction parallel to the front main face for receiving a complementary pin.
