Abstract: A composite diaphragm is provided to include a base layer and a micro-nanometer ceramic layer disposed on the surface of the base layer. The micro-nanometer ceramic is a structural material that has great stiffness and toughness, such that the composite diaphragm made of micro-nanometer ceramic manifests characteristics of high stiffness, high toughness, and great ductility. Thus, the composite diaphragm allows large deformation at room temperature to achieve high capability of producing high-definition tone.

Abstract: Subject matter described herein includes a multi-layer search-engine index. Accordingly, the search-engine index is divided into multiple indexes, each of which includes a respective set of information used to serve (i.e., respond to) a query. One index includes a term index, which organizes a set of terms that are found among a collection of documents. Another index includes a document index, which organizes a set of documents that are searchable. A computing device is used to serve the search-engine index (i.e., to analyze the index when identifying documents relevant to a search query). For example, a solid-state device might be used to serve the multi-layer search-engine index.

Abstract: Provided is a composite diaphragm which includes a base layer and at least a graphyne including layer. The base layer has a central portion and a peripheral portion disposed at the periphery of the central portion. The graphyne including layer is disposed on the surface of the base layer. As graphyne is a lightweight and highly rigid material with a two-dimensional structure, composite diaphragms made of graphyne manifest characteristics, such as high stiffness, high toughness and low density, and thus achieve high practicability, such as high durability and high capability of producing high-definition tone.

Abstract: It is inevitable for the tight closure of a ball valve to be disturbed by its ball's wedging action, and its ball seat is an upset impulse amplifier with an inherent disturbance resistance index or a sealing maintaining factor m. The ball valve seat designed with equilateral triangle section methods of the invention can positively ensure itself a resistance to ball-wedged disturbance from eccentric drive to make a ball valve realize its tight closure by the floated pressure of balls or seats onto each other and ensure that the ultimate rotational resistance to the ball only relates to the ultimate pressure from/on one seat.

Abstract: A structure and method for air cavity packaging, the structure comprises a carrier having plural die pads and leads, plural dies, plural wires, plural walls, and a lid. The dies are mounted on the die pads. The wires electrically connect the dies to the leads. The plural walls are disposed on the carrier and form plural cavities in a way that each cavity contains at least one die pad and plural leads, and each wall is provided with at least one air vent for exhausting air to the outside. The lid is attached on the plural walls via an adhesive agent to seal the plural air cavities, so that the plural connected air cavity packages are formed.

Abstract: Methods, computer systems, and computer-readable media for generating semantic ranking features using a forward index are provided. A search query is received and is analyzed for one or more semantic units including semantic patterns, topical categories, and entities. A forward index comprising a plurality of documents is accessed and semantic units associated with each of the documents are analyzed. The semantic units include semantic patterns, topical categories, unigrams, bigrams, and entities. Documents who share substantially similar semantic units with the search query are identified, and the ranking of the identified documents is adjusted based on the substantially similar semantic units.

Abstract: Architecture that performs incremental computing for web searches by employing methods at least for storing the results of repeat queries on unchanged webpages and for computing results for the repeated queries. The architecture includes one or more algorithms for pre-computing query results on index servers, for only selectively choosing index servers whose result for a query change for a query computation process, and for re-using the unchanged web pages stored in the cache and computing results upon changed index and unchanged index separately.

Abstract: A stem shoulder seal with double rings is composed of a sealing ring, a clamping ring and a spherical or conical stem shoulder, and the sealing ring is of a self-energized seal designed to its ultimate allowable strength and automatically free of any load beyond its ultimate strength. An assembly of independent dual stem seals, consisting of a stem shoulder seal with double rings, a stem cylinder seal with triangular sections and an isolating mating, can ensure that a stem has three seals which get well seated automatically at the same time to bear an identical ultimate medium pressure independently or without any mutual interference in service when assembled to the extent that the stem operating torque is just definitely increased, thereby ensuring that a stem sealing has a triple safety.

Abstract: A distributed system checker may check a distributed system against events to detect bugs in the distributed system. The events may include machines crashes, network partitions, and packet losses, for example. The distributed system checker may check a distributed system that can have multiple threads and multiple processes running on multiple nodes. To obtain control over a distributed system, a distributed system checker may insert an interposition layer between a process and the operating system on each node.
