摘要:
Electromigration activity is decreased and lifetime is extended in solder stripes employed as conductors and terminals on microelectronic devices by forming an alloy of a solute element, such as copper, with tin in a lead/tin solder and providing a substantially uniform distribution of particles of the intermetallic compound in the solder. The concentration of the solute element is maintained at less than about three times the tin concentration and less than about 10% of the amount of the solder.

Systems for a truck box cover and more particularly to a truck box cover system configured to transform to suit multiple load types and still protect the load from outside elements. The truck box cover system has a plurality of electrically controlled telescoping columns and sides made of compliant material for raising and lowering the cover and maintaining a closed configuration.

System and method for processing video information are disclosed and may include receiving, at a processing device, packetized digital video from a sensor. The packetized digital video may be decoded within the processing device, into source video formatted frames. The decoding may use at least one shared library function call. The source video formatted frames may be converted within the processing device into destination video formatted frames. The destination video formatted frames may be transferred to a video processing system. The destination video formatted frames may be stored, prior to the transferring, in shared memory within the processing device. The storing of the destination video formatted frames may include allocating at least one memory block of the shared memory, and associating the allocated at least one memory block with a memory pointer.
摘要:
Multi-layer golf balls having a thin, relatively hard outer core layer surrounding a large, relatively soft inner core layer are provided. The inner core layer generally has a diameter of from 1.5 inches to 1.55 inches. The outer core layer generally has an outer diameter of from 1.6 inches to 1.64 inches. A cover is provided to surround the outer core layer. A moisture barrier layer is optionally provided between the outer core layer and the cover.
摘要:
Golf balls consisting of a dual core and a single layer cover are disclosed. The dual core consists of an inner core layer formed from a rubber composition and an outer core layer formed from a highly neutralized polymer composition. The Shore C hardness of the outer core layer's outer surface is preferably greater than the material hardness of the inner cover layer, and more preferably is 56 Shore D or greater.
摘要:
Disclosed herein are heterogeneous golf ball compositions comprising a thermoplastic polymer matrix and discrete particles of thermoplastic polymer dispersed within the matrix.
摘要:
Multi-piece golf balls having a multi-layered solid core and multi-layered cover are provided. In one version, a five-piece ball is formed, wherein the inner cover layer is made of a thermoplastic composition such as a highly neutralized (HNP) composition. The outer cover layer is made of a composition comprising a polyurethane, polyurea, or copolymer or blend thereof. In a second version, a six-piece ball having inner and intermediate cover layers that also can be made of HNP compositions is produced. The five and six-piece balls also include multi-layered core structures with a center made of a thermoset rubber. The finished balls have high resiliency and rebounding properties.
摘要:
Golf balls that have at least one layer formed from a cationic polyurea material. In particular, the compositions of the invention, which include a polymer backbone including urea linkages with cationic groups, may be formed from an isocyanate-containing component and an isocyanate-reactive component, at least one of which includes precursor cationic groups, in the presence of an alkylating, quaternizing, or ternarizing agent.
摘要:
Multi-piece golf balls having a core made of a composition comprising a polybutadiene rubber blend are provided. The blend includes a non-metallocene catalyzed polybutadiene rubber and a metallocene-catalyzed polybutadiene rubber. Catalysts such as neodymium, nickel, and cobalt based catalysts may be used to make the non-metallocene catalyzed rubber. Catalysts such as ferrocene, cobaltocene, nickelocene, titanocene dichloride, zirconocene dichloride, and samraocene based catalysts may be used to make the metallocene-catalyzed rubber. The golf ball may contain single layered core or multi-layered cores. The core is surrounded by a cover having at least one layer. The resulting ball has high resiliency and a soft compression feel.
摘要:
Golf balls having a core comprising a polyalkenamer rubber composition are provided. The rubber composition may further include other rubbers such as, for example, polybutadiene, polyisoprene, ethylene propylene rubber, ethylene propylene diene rubber, and styrene-butadiene rubber. The rubber composition helps improve resiliency of the core and provides the ball with a comfortable and soft feel. In one version, a solid, single core having an outer surface and geometric center is provided, wherein the outer surface has a hardness greater than the hardness of the geometric center to define a positive hardness gradient of at least 10 Shore C. In a second version, a dual-core having an inner core and surrounding outer core layer is provided. The inner core has a positive hardness gradient, while the outer core has a zero; negative; or positive hardness gradient.
