The invention relates to a container universal ventilator containing electric label and the container using the ventilator. The container has through hole on the case, and the ventilator is installed onto the through hole from external. The hollow cavity of the ventilator has electric label. The relative information of the container is recorded in the electric label that could be read by reader in wireless mode. The invention would not influence to the current container, and would be convenient to acquire the information of contains. It is benefit for standardization producing and saves industry cost of using electric label in container industry.

The invention discloses a polyacrylamide microgel as well as a preparation method and application thereof. The particle size of the polyacrylamide microgel is 30-150 micrometers, acrylamide, sodium acrylate, N,N'-bisacrylamide, 2-acrylamide-2-methylpropanesulfonic acid sodium, styrenesulfonate and the like serve as polymerized monomers, white oil and the like serve as disperse phases, and the polymerized monomers and the disperse phases are subjected to thermal initiation suspension polymerization to obtain the polyacrylamide microgel. The polyacrylamide microgel synthetized by the method canbe directly injected into an oil layer without being processed and has a good plugging effect.

It is an LED positioning devices, which enable LED unplug the circuit board position rapidly and connect to the circuit connections. It may further provide LED based perspective changes interpolation so that LED can be used in richer modeling articles. The mentioned LED positioning device at least includes a number of light-emitting diodes and a circuit board. The circuit board fix with a number of LED pins corresponding number of terminals, the terminal with the corresponding jacks for the plug pins, the terminal and circuit boards were laid by the circuit conduction. So allow the mentioned LED pins inserted in the corresponding terminals, locate the LED on the circuit board position and complete the circuit links with the circuit board directly.

The invention discloses a transverse diffusion metal oxide semiconductor (MOS) device with low on-resistance. The device comprises a P-type well layer and an N-type lightly doped layer which are positioned in a P-type substrate layer, wherein a gate oxide layer is arranged above the P-type well layer in an area between a source area and the N-type lightly doped layer; at least two grooves are formed on the upper part of the P-type well layer between the source area and the N-type lightly doped layer, and the etching depth of the grooves is between one fourth and one fifth of the junction depth of the source area; the N-type lightly doped layer consists of a first N-type lightly doped area, a second N-type lightly doped area and a P-type lightly doped area; the doping concentration of the first N-type lightly doped area is higher than that of the P-type lightly doped area, and the doping concentration of the P-type lightly doped area is higher than that of the second N-type lightly doped area; and the proportional range of the doping concentrations of the first N-type lightly doped area and the second N-type lightly doped area is 1.2:1-1.3:1. According to the power MOS device with the low on-resistance, the volume of the device is reduced, the response time of the device is shortened, the frequency characteristic of the device is improved, and the long-term stability of the performance parameter of the device is achieved.
