摘要:
A tube used for heat transfer has adjacent fins extending from an outer surface of the tube with a channel between the fins. The fins include a roof formed over the channel, and holes penetrate the roof into the channel. The fin, including the roof, is monolithic with the tube body. Helical ridges are formed on a tube inner surface, and the tube body includes an indentation in the outer surface which extends the tube body inner surface towards a tube axis.

A method for updating a document by means of appending an updated file to the document comprises the steps of reading an original document; initializing the original document to have a name and an index number for correspondingly identifying the original document; opening the updated file; establishing a name for correspondingly identifying the updated file; and appending the updated file to the original document to form an updated document. By utilizing the method, the file size and the download time of the updated document are reduced, as well as enabling a user to easily carry out a query to documents with different versions and a switching between them.

A wine decanter includes a housing and a variation magnetic field generator, where the variation magnetic field generator is configured to generate a variation magnetic field, and the variation magnetic field generator generates the variation magnetic field, so that a movement component that can sense a magnetic field moves in wine to make the wine move, thereby increasing contact between the wine and air. The decanting device includes a wine container, a movement component, and the decanter according to any one of the foregoing, where the movement component is placed inside the wine container, the decanter is connected to the movement component by using a magnetic field, and the decanter generates a variation magnetic field to drive the movement component to perform decanting. The structure of the decanter is simplified, thereby facilitating miniaturization, and making it convenient to carry the decanter, and also reducing noises.

摘要:
An electrically-conductive layer of material having a composition comprising lanthanum and strontium is described. The material is characterized by a microstructure having bimodal porosity. Another concept in this disclosure relates to a solid oxide fuel cell attached to at least one cathode interconnect by a cathode bond layer. The bond layer includes a microstructure having bimodal porosity. A fuel cell stack which incorporates at least one of the cathode bond layers is also described herein, along with related processes for forming the cathode bond layer.
摘要:
A multi-block thermoplastic polyurethanes system which incorporates polyhedral oligomeric silsesquioxane into conventional biodegradable thermoplastic polyurethanes built up by poly(ε-caproactone) and polyethylene glycol blocks, resulting in biostability. The multi-block thermoplastic polyurethanes are synthesized from lysine-diisocyanate with poly(ε-caprolactone)-diol, polyhedral oligomeric silsesquioxane-diol, and poly(ethylene glycol) using a one-step synthesis process.

Back contact solar cell modules and methods of manufacturing the same. The solar cell module comprises a back surface with a plurality of first electrodes and a plurality of second electrodes formed thereon, the plurality of first electrodes and the plurality of second electrodes being of opposite polarities, the back surface being configured to form an electric field thereon of the opposite polarity as the plurality of first electrodes; a first connecting strip electrically connecting the plurality of first electrodes; and an insulative member between the back surface and the first connecting strip.
摘要:
A method for regulating network traffic may be provided. The method may comprise: measuring usage of a CPU; determining if the CPU usage is greater than an overload threshold value; halting the increase of a data traffic shaping rate associated with traffic regulated by the CPU if the CPU usage is greater than the overload threshold value; determining if the CPU usage is greater than an overflow threshold value; and decreasing the data traffic shaping rate associated with traffic regulated by the CPU if the CPU usage is greater than the overflow threshold value for improving session setup speed.
