Abstract:
Semiconductor die packages, methods of making said packages, and systems using said packages are disclosed. An exemplary package comprising at least one semiconductor die disposed on one surface of a leadframe and electrically coupled to at least one conductive region of the leadframe, and at least one passive electrical component disposed on the other surface of a leadframe and electrically coupled to at least one conductive region of the leadframe.
Abstract:
Disclosed are semiconductor die packages, methods of making them, and systems incorporating them. An exemplary package comprises a first substrate, a second substrate, a semiconductor die disposed between the first and second substrates, and an electrically conductive member disposed between the first and second substrates. The semiconductor die has a conductive region at its first surface that is electrically coupled to a first conductive region of the first substrate, and another conductive region at its second surface that is electrically coupled to a first conductive region of the second substrate. The conductive member is electrically coupled between the first conductive region of the second substrate and a second electrically conductive region of the first substrate. This configuration enables terminals on both surfaces of the semiconductor die to be coupled to the first substrate.
Abstract:
A die package is disclosed. The die package includes a substrate, a first device attached to the substrate, and a leadframe structure attached to the substrate. The leadframe structure includes a portion disposed over the first device, and a second device is attached to the first portion of the leadframe structure.
Abstract:
Methods and apparatus for combinatorial (i.e., high-throughput) materials research, such as catalysis research, that involves parallel apparatus for simultaneously effecting mechanical treatments such as grinding, mixing, pressing, crushing, sieving, and/or fractionating of such materials are disclosed. The methods and apparatus are useful for mechanically treating catalysis materials and other solid materials, including without limitation, electronic materials such as phosphors, colorants such as pigments, and pharmaceuticals such as crystalline drugs or drug candidates. The simultaneous protocols and parallel apparatus offer substantial improvements in overall throughput for preparing arrays of materials, such as catalysis materials.
Abstract:
The present invention addresses at least four different aspects relating to catalyst structure, methods of making those catalysts and methods of using those catalysts for making alkenyl alkanoates. Separately or together in combination, the various aspects of the invention are directed at improving the production of alkenyl alkanoates and VA in particular, including reduction of by-products and improved production efficiency. A first aspect of the present invention pertains to a unique palladium/gold catalyst or pre-catalyst (optionally calcined) that includes rhodium or another metal. A second aspect pertains to a palladium/gold catalyst or pre-catalyst that is based on a layered support material where one layer of the support material is substantially free of catalytic components. A third aspect pertains to a palladium/gold catalyst or pre-catalyst on a zirconia containing support material. A fourth aspect pertains to a palladium/gold catalyst or pre-catalyst that is produced from substantially chloride free catalytic components.

Abstract:
Catalysts for oxidative dehydrogenation of alkane to one or more olefins, exemplified by ethane to ethylene, are disclosed. The catalyst comprises a mixture of metal oxides having as an important component nickel oxide (NiO) and gives high conversion and selectivity. For example, the catalyst can be used to make ethylene by contacting it with a gas mixture containing ethane and oxygen. The gas mixture may optionally contain ethylene, an inert diluent such as nitrogen, or both ethylene and an inert diluent.
Abstract:
A four-stroke cycle internal combustion engine comprises a connecting rod which has an oil dipper at a big-end thereof, a crankcase, a partition wall which surrounds the connecting rod to provide a separation between the crankcase and an oil reservoir and an outer wall which is outward of and surrounds the partition wall and is connected to the partition wall at upper ends thereof so as to define the oil reservoir below the crankcase. A slit is formed in the partition wall below the connecting rod to allow the oil dipper to protrude into and be withdrawn from the oil reservoir to splash oil in the oil reservoir for lubrication by the oil dipper through a swinging motion of the connecting rod. The depth of the oil reservoir is shallower at least in a part of an outer edge area thereof than that below the oil dipper so that a tip of the oil dipper reaches the oil level even when the oil flows into the outer edge area of the oil reservoir.
