摘要:
A water adhesive, being a hybrid solution containing gelatin, a water-soluble polymer and water, or comprising gelatin, a water-soluble polymer and water, is disclosed. The preparation method of the water adhesive and application of the water adhesive in manufacture of a positive plate of a lithium ion battery are also disclosed. The present invention has the following beneficial technical effects: The water adhesive with the above formulation can achieve a good coating effect; each ingredient is easily available, with a lower cost; the water adhesive can be prepared through simple steps, making the manufacture easy to implement, with broad prospects for industrial application.

A probe includes a circuit board, an electric field detecting probe, and a magnetic field detecting probe. The electric field detecting probe and the magnetic field detecting probe are located on the circuit board. An anti-jamming distance between the two detecting probes is a multiple of 5 millimeters and is greater than or equal to 10 millimeters.

Quad Flat No-Lead packaged devices are manufactured using two singulation operations with two different saw blades of varying widths with the first singulation operation using a wider saw blade than the second singulation operation. Between singulation operations, the exposed portions of the leads are plated with a solderable metal. By performing the second singulation operation within the first cut made by the first singulation, at least half of the exposed metal of the leads remains plated. Thus, better solder joints may be formed, which allows for simpler visual inspection.

A method for measuring hearing aid compatibility (HAC) includes providing a probe and scanning testing points of a testing region obtained by the probe. The probe includes a circuit board, an electric field detecting probe, and a magnetic field detecting probe. The electric field detecting probe and the magnetic field detecting probe are located on the circuit board.
摘要:
The present invention discloses a docbase management system, including a first module, adapted to parse a received invocation from an application and generate an execution plan which comprises operations on physical storage; a second module, adapted to execute the execution plan to schedule a third module to execute the operations on physical storage in the execution plan; and the third module, adapted to execute the operations on physical storage in the execution plan under the scheduling of the second module. Since the implementation of the docbase management system is divided into hierarchies, and the hierarchies are independent of each other, the docbase management system is well extendable, scalable and maintainable.
