摘要： This invention offers a functional vinyl halide polymer that has excellent processing properties for the end-user processing without any extra processing aid. This functional vinyl halide polymer has good fusion, lubrication and melting strength in processing. The finished products show a good characterization of high transparence, low air-mark and low flow-mark. The functional vinyl halide polymer is produced by a solution, bulk or suspension polymerization. Vinyl halide or a monomer mixture comprising mainly vinyl halide is polymerized in an aqueous medium in the presence of an acrylic copolymer latex/powder to obtain the functional vinyl halide polymer. The functional vinyl halide polymer manufacturing process mainly comprises the copolymerization or graft-polymerization of: (A) 90.0 wt %˜99.9 wt % based on the total composition of the vinyl halide or the monomer mixture, and (B) 10.0 wt %˜0.1 wt % based on the total composition of the alkyl acrylate monomers or the acrylic polymer latex/powder, wherein the former can be added stepwisely or all in one time and the later can be charged continuously into reactor during polymerization or charged into a reactor before polymerization.

摘要： A land grid array (LGA) connector (1) according to an embodiment of the present invention includes an insulative housing (2), a stiffener (3) coupled to the housing, and a plurality of ribs (23) projecting from a periphery edge of the housing. The stiffener defines an opening (31) for surrounding the housing. Each of the ribs has a base defining a mating surface (2321) and a mounting surface (2312). The stiffener is coupled to the housing by the rib mating surface abutting against a wall face (32) of the stiffener opening, and the rib mounting surface resting on a peripheral edge (320) of the stiffener that defines the opening. As such, a reliable coupling between the stiffener and the housing is achieved, thereby having no possibility of releasing the housing from the stiffener by an external, improper force.

摘要： An IC socket includes a plurality of terminals (7) arranged in a matrix defined by row and column directions perpendicular to each other. The terminal includes a contact arm (73) extending from a middle portion of the terminal. The contact arm includes a first resilient arm (731) extending essentially towards the row direction in a first direction, from a top view, and a second resilient arm (733) angled with the first resilient arm and extending essentially towards the row direction in a second direction, from the top view, different from the first direction. Since the second resilient arm extends essentially toward the row direction, rather than parallel to the row direction, and a larger recess is formed between respective resilient arms of adjacent terminals in a same row, there will not be apt to form a short circuit between any portions of the first lower resilient arm and the second upper resilient arm.

The built-in-self-test circuit for phase locked loops-jitter testing comprises a phase locked loop unit electrically connected with a frequency divide unit. The frequency divide unit is electrically connected with a signal conversion unit. A signal computation unit is electrically connected with the signal conversion unit. After an input signal is provided to and processed by the phase locked loop unit, the signal conversion unit outputs a self test output signal exhibiting the occurrence situation of jitter signal of the phase locked loop unit. High frequency signals encountered during test of jitter signal of phase locked loops can therefore be reduced.

摘要： Method and related apparatus for realizing frequency-multiplication by generating a high frequency signal according to a plurality of low frequency signals. The method includes: according to a plurality output signals generated by a phase-locked loop (PLL) or a delay-locked loop (DLL), generating a plurality of reference signals with a same frequency and different phases; when a number of the reference signals with signal level high is greater than a number of the reference signals with signal level low, making a signal level of the output signal remains a first level; otherwise, making the signal level of the output signal remains a second level substantially different from the first level. Thus the frequency of the output signals is a multiplication of the frequency of the input signals.
