摘要:
The present invention includes a load-adaptive power generator including a feedback detecting module, a load determining module, a load driving module, and a control module. The feedback detecting module detects a load voltage of a load device, and converts the load voltage into a feedback voltage. The load determining module determines whether the feedback voltage is within a preset range for generating a periodical load driving signal. The load driving module has a plurality of driving units and at least one switch. The driving units drive the load device according to the load driving signal, and at least one driving unit receives the load driving signal through the switch. The control module turns on the switch when the frequency of the load driving signal is less than a frequency threshold. Accordingly, the load-adaptive power generator of the present invention can save energy.

The present invention provides a mixed crystalline form VIII of agomelatine, its method of preparation, application and pharmaceutical composition. The said mixed crystal consists mainly of crystalline form VI of agomelatine. The said mixed crystalline form is stable and has good reproducibility. Through stability tests, it has been found to be superior to the crystalline form VI in terms of stability. As a result, the crystalline form VIII of the present invention possesses advantages in pharmaceutical preparation.

The invention provides a method of improving dewatering efficiency, increasing sheet wet web strength, increasing sheet wet strength and enhancing filler retention in a papermaking process The method improves the efficiency of drainage aids or wet web strength aids or wet strength aid by coating at least some of the filler particles with a material that prevents the filler materials form adhering to a those additives. The drainage additive or wet web strength additive or wet strength aid holds the cellulose fibers together tightly and is not wasted on the filler particles.

The invention provides a method of producing paper with a higher proportion of mineral filler particles than is otherwise be possible without the expected loss in paper strength. The method allows for the use of the greater amount of filler particles by coating at least some of the filler particles with a material that prevents the filler materials form adhering to a strength additive. The strength additive holds the cellulose fibers together tightly and is not wasted on the filler particles. The method is particularly effective when the filler particles are a PCC-GCC blend and when the GCC particles are coated with the adherence preventing coating.

The invention is directed towards methods, compositions, and apparatus for increasing the strength of paper made out of a furnish having a large proportion of OCC. The method involves the following steps: 1) Providing a paper furnish having a large amount of OCC in it, 2) adding strength promoter to the furnish prior to adding a strength agent to the furnish, 3) adding a strength agent to the furnish, and 4) making a paper product from the furnish. This method allows cheap OCC material to be used in a papermaking process without the quality problems that the anionic trash in OCC typically causes. Thus paper products having low costs and high quality can be produced.

The present invention provides a method for testing ports of a computer. The method includes steps of: connecting the testing ports and the non-testing ports of the computer according to a configuration document; creating virtual devices corresponding to the non-testing ports; analyzing corresponding relations between the virtual devices, the non-testing ports, and the testing ports; analyzing a count of the testing ports; and determining whether the testing ports are in good working condition by determining whether the count of the testing ports is equal to a count of the configuration records. A related system is also disclosed.
