Abstract: In a land grid array connector for electrically connecting a chip module to a printed circuit board, comprising: an insulative housing and a plurality of contacts, the housing including side walls and a central portion surrounded by the side walls, the central portion having a first mounting face toward the chip module, a second mounting face toward the printed circuit board, and a plurality of grooves receiving the contacts, at least two of the side walls each including a spring arm extending into the central portion, the improvement wherein a protrusion is disposed on at least one of the spring arm and the associated side wall.

Abstract: An LGA connector contact (30) includes a base (31), and a pair of spring arms (32) extending from the base. Each of the spring arms includes an extending section (320), a connecting section (321), and a contacting section (322) adapted for engaging a circuit board's contact pad. The contacting section has an exterior side and an interior side with a recess (323) on the exterior side of the contacting section around a middle portion of the contacting section so as to define at least a pair of contact regions (324) adjacent the recess. The LGA contacting portion is configured to have its contact regions electrically engage with an un-oxidized portion of the circuit board's contact pad, thereby achieving an effective electrical connection between the LGA connector contact and the corresponding circuit board pad.

Abstract: The present invention is based on the discovery that certain chemical compounds isolated from Chinese medicinal herbs are useful as anti-microbial agents, e.g., anti-bacterial agents, anti-fungal agents, and the like. In particular, the present invention provides compositions useful for treating microbial infections such as, for example, oral microbial infections, including periodontal disease and dental caries.

Abstract: The present invention describes the use of agents that interact with major histocompatibility complex (MHC) HLA class I molecules, such as &bgr;2-microglobulin, or antibodies that bind to &bgr;2-microglobulin, for the treatment and prevention of multiple myeloma and other types of cancer. The anti-cancer therapeutics of the present invention interact with MHC molecules on the surface of the tumor cell to increase apoptosis and inhibit cell growth and proliferation. For example, in an embodiment, anti-&bgr;2-microglobulin antibodies inhibit the growth of multiple myeloma cells by over 90%. Thus, the present invention describes a new class of anti-cancer therapeutics and methods of use.

Abstract: According to the present invention, it is possible to produce emulsions containing a material that are insoluble or that have low solubility with respect to water and oil in a high concentration, so as to obtain emulsions which can be preserved for a long period of time. More specifically, ethanol, to which polyglycerol oleic acid ester (PG) is added, and vegetable oil, are stirred with a homogenizer or an emulsification method such as a membrane emulsification or a microchannel emulsification, thereby obtaining E/O type emulsions or E/O/W type emulsions wherein ethanol drops in which polyphenol is dissolved in a high concentration are dispersed into vegetable oil.
