An application method of silicon powder and raw material silicon brick with good filling property in a mono-crystal or a multi-crystal furnace involves pressing silicon powder having a particle size of 0.1 to 100 micrometers into silicon brick having weighing 0.2 to 2,000,000 grams by cold or hot isostatic pressing, then charging it into a mono-crystal or multi-crystal furnace. The pressure range of cold isostatic pressing is 10 MPa to 800 MPa. The pressure range of hot isostatic pressing is 10 Mpa to 800 Mpa. The temperature range for the method is 30° C. to 1,400° C.; The raw material silicon brick is used as the original raw material of silicon crystal growth in the production of solar cells or semiconductor.

An electron gun (1) includes an emitter (2), a tubular support (3) and an adaptor (4) for receiving the emitter. The adaptor includes a tapered plugging surface (7) and the tubular support includes a correspondingly tapered seating surface (9) for receiving the plugging surface. The plugging surface and seating surface have conical profiles which help to position the adaptor concentrically with the support.

The present invention relates to the coordinated control method of torsional stress relay in large thermal power plants' generators (300 MW and above), which will be adopted when shaft torsional oscillations occur. This invention also publishes a method of realizing selective trip the generators and the trip criterions which are implemented by the torsional stress relay and coordinated control master station (Tmaster). Tmaster will real-time monitor the operating status of the generators and TSR, TMaster will also real-time generate a trip priority level sequencing by analyzing the unit output.When generators occur subsynchronous resonance and shaft torsional oscillation, this method can ensure that TSR will trip some generators of the power plant according to the real-time generated trip strategy to inhibit the shaft torsional oscillation and safeguard the units. This method can also avoid the tremendous economic loss caused by tripping all the generators, and that will reduce the hazard to the transmission grid.

A method of analyzing customer behavior, where customers are engaged in customer-to-customer transactions in the third-party network, includes the transformation of data representing the customer-to-customer transactions from a data representation to a network representation, and then analyzing the network representation. The network representation includes a set of nodes and a set of links where each node represents a customer and each link represents a transaction between two of the customers.
摘要:
A printer control method includes the following steps: setting triggering conditions for executing functional items and for startup a configuration menu; executing a functional item if the key information had fulfilled the triggering condition for executing the functional item; and launching a configuration menu if the key information had fulfilled the triggering conditions for startup the configuration menu. By setting the triggering conditions for executing functional items and for startup a configuration menu, then determining whether the key information has fulfilled the triggering conditions for executing functional items and for startup a configuration menu, the printer directly executes the functional item as long as the key information has fulfilled the triggering condition for executing the functional item. When the printer is powered on, it skips the step of launching the configuration menu, operates conveniently and saves paper.

Reducing coherency problems in a data processing system is provided. Source code that is to be compiled is received and analyzed to identify at least one of a plurality of loops that contain a memory reference. A determination is made as to whether the memory reference is an access to a global memory that should be handled by a direct buffer. Responsive to an indication that the memory reference is an access to the global memory that should be handled by the direct buffer, the memory reference is marked for direct buffer transformation. The direct buffer transformation is then applied to the memory reference.

Systems and methods for managing the effect of electromagnetic radiation on electronic devices, are provided. The systems and methods includes determining a location of an electronic device within an environment; determining a level of electromagnetic radiation in a location of interest; and implementing corrective action to limit the effect of the electromagnetic radiation. The location of interest can include at least one of a current location; a future location; and a location that is proximal to the current location of the device. Determining the amount of electromagnetic radiation at a location of interest can include estimating a level of electromagnetic radiation at the location based on equipment stationed at that location; a scheduled use of equipment stationed at that location; and receiving a signal indicating a level of electromagnetic radiation from at least one detector positioned at the location of interest.

A GPS RF Front End IC containing a Programmable Frequency Synthesizer is disclosed. The GPS RF front end IC having a programmable frequency synthesizer allows a relatively fixed internal frequency plan while able to use a number of different reference frequencies provided by the host platform, which can be a wireless phone, or other such device, which can provide an accurate reference frequency signal.
摘要:
In some embodiments, a silent proactive handoff is performed wherein a mobile device that is using a current network to transport its application traffic uses its silent periods to connect to at least one target network temporarily and uses this temporary connectivity to perform actions needed for handoff into the target network. Among other things, with such a silent proactive handoff approach, e.g., if handoff actions to a target network fail during silent periods, there can still be essentially no impact on the applications.
摘要:
For IP-based wireless systems in which base stations are connected by an IP network and communication among base stations is not controlled by the centralized management, a new system and method for realizing soft handoff by using encapsulation in order to distribute and gather a reproduced packet by the serving base station with other base stations and to transfer the serving role between the base stations as the mobile station moves is described.
