A method of re-circulating washwater used to clean production components for the manufacture of fibrous insulation, e.g. fiberglass is disclosed. The method includes providing a bulk washwater recovery loop to re-circulate washwater used to clean the downstream air components, as well as a separate hoodwall washwater recovery loop to re-circulate hoodwall washwater. Re-circulated hoodwall washwater may be used to clean the forming hood components and for preparation of binder dispersions. In the latter case, the pH of the hoodwall washwater is measured and the binder dispersion may be prepared with 100% hoodwall washwater, 100% makeup water, or a blend of each depending on and in response to the pH measurement.

A method and an apparatus for tracking uncertain signals in the simulation of chip design are provided. The method comprises: generating a directed graph which contains sequential logic devices and IO devices from the netlist of chip design, wherein the directed graph illustrates the signal association among the sequential logic devices and IO devices; obtaining the signals related with the sequential logic devices and IO devices from the simulation results, wherein the signals contain a plurality of uncertain signals; and back tracing at least a part of the plurality of uncertain signals along the directed graph to determine the device which firstly generates an uncertain signal. The corresponding apparatus is also provided. With the above method and apparatus, uncertain signals can be traced and their source can be determined, which improves the debugging efficiency.

An automatic nail-feeding mechanism for a power tool having a striking assembly having a striking rod movable in a linear reciprocating manner feeds a nail to be struck to a front end of the striking rod. The automatic nail-feeding mechanism has a driving part movable between a first position and a second position in a direction of a reciprocating motion of the striking rod and a nail-storing element is provided with nails arranged at a fixed pitch, the nail-storing element being fed a distance of the fixed pitch towards the striking rod when the driving part moves from the first position to the second position and then from the second position to the first position in a stroke of the reciprocating motion thereof.

Architecture that maps document data (e.g., XML-extended markup language) into columns of one table, thereby avoiding schema normalization problems through special data storage. Moreover, an algorithm is described that can translate a query (e.g., in XPath (XML path language), a query language for navigating through document elements and attributes of an XML document) into a relational algebra query of the document column representation. Based on the characteristics of the new mapping, query rewriting rules are provided that optimize the relational algebra query by minimizing the number of joins. The mapping of XML documents to the table is based on a summary structure and a hierarchical labeling scheme (e.g., ordpath) to enable a high-fidelity representation. Annotations are employed on the summary structure nodes to assist in mapping XML elements and attributes to the table.
摘要:
A power supply and methods are provided. In one implementation, the power supply includes a switching circuit and a converter. The switching circuit includes a first transistor and a second transistor, and the converter includes a capacitor and an inductor. The switching circuit alternately switches an input voltage to the converter. The power supply further includes a controller operable to adjust a switching frequency of the first transistor and the second transistor to substantially match a resonant frequency of the capacitor and the inductor.

A Direct Memory Access controller controls access to memory in a data processing system via a system bus. The controller is made up of a data load unit configured for performing load operations with data. A data computation unit is configured for performing data conversion and is pipeline connected in sequence to the data load unit. A data store unit is also pipeline connected in sequence to the data computation unit and is configured for performing burst store operations onto a system bus for storage in system memory.

A process for the manufacture of agomelatine and its intermediate N-[2-(7-methoxy-1-naphthyl)ethyl]phthalimide is provided and includes reacting 7-methoxy-1-naphthyl ethanol (III) with benzenesulfonyl chloride to obtain 7-methoxy-1-naphthylethyl benzene sulfonate (IV), which is reacted with potassium phthalimide to produce N-[2-(7-methoxy-1-naphthyl)ethyl]phthalimide (II); and subjecting N-[2-(7-methoxy-1-naphthyl)ethyl]phthalimide (II) to alkaline hydrolysis and acetylation, to obtain agomelatine.
摘要:
An auto hammer has a housing, a grip portion and a striking device. The striking device has a striking rod that can strike a fastening element using a liner reciprocating motion. The striking device also has an associated clamping mechanism for clamping the fastening element. The clamping mechanism includes a clamping member, a driving part and a sliding member, wherein the clamping member is pivotally arranged in the sliding member and is connected to the driving part, and the driving part can rotate relative to the sliding member so as to cause the clamping member to rotate pivotally in the sliding member. The clamping mechanism may thus firmly clamp the fastening element in a manner that is convenient for users.
