Abstract: The present disclosure provides a method for separating a neural crest derived cell from peripheral blood. In the present disclosure, a mononuclear cell is separated from the peripheral blood and then directly cultured, thereby maximizing use of a neural crest stem cell with a differentiation potential to avoid loss of the neural crest stem cell. In the method of the present disclosure, a sample to be separated is derived from the peripheral blood. The method shows less trauma and low cost. Most importantly, compared to extracting the neural crest derived cell from tissues, the neural crest derived cell extracted from the peripheral blood can be used clinically as a type of biomarker.

LED wafers (1) are provided on one side of a heat spreading plate (3) made of copper, aluminum or copper-aluminum composite material with a thickness of more than 0.4 mm and with an area of 5 times of the sum area of the LED wafers larger to reduce the heat-flux density. A high-voltage insulation plate (2) made of a ceramic wafer with a thickness of more than 0.15 mm is provided on the other side of the heat spreading plate (3). The heat spreading plate (3) is separated and insulated by an outer layer insulator (4) with the high-voltage insulation plate (2). This kind design can effectively reduce the internal conduction thermal resistance and raise the insulation strength, and the manufacturing cost can be reduced effectively also.

Abstract: A flat heat pipe radiator and a new kind of portable computer are provided. The air convective extended heat exchange surface of the radiator surrounds the fan impeller and is facing the air outlet of the impeller, the heat transport distance in heat pipe is shortened, the fan shell and the diffusion channel in the shell can be left out, so the size, weight and cost of the radiator are decreased effectively. The restrictions to a radiator when installing are reduced, which helps to implement the standardization of the radiator series. The new kind of portable computer helps to decrease weight and thickness and improve the heat dissipation further.

Abstract: A flat radiator with flat type heat pipe and its application for portable computers is provided. The heat pipe in a radiator use tubular type and plate type structures. An air convective extended heat exchange surface surrounds and is over against the fan impeller, such that the radiator is extremely compacted, and the heat transport distance in heat pipe is shortened. Further introducing enhanced convective heat transfer structure and setting the fins according to the aerodynamics improve the heat dissipating capacity. The restrictions to a radiator when installing are reduced, which helps to implement the standardization of the radiator series. Also portable computers using the radiator are provided.

Abstract: The present invention provides a small ozone gas-water mixing pump. The rotation of the leaves drives water to produce intense turbulence vortex, and the bubbles in the water are torn up producing more and smaller bubbles, so that the gas-water contacting area is enlarged, and the ozone is efficiently dissolved into water. The magnetic force between the permanent magnet A on impeller and the permanent magnet B on motor enables the motor driving the impeller without using shaft, so as to avoid sealing problems of the pump driving shaft. The present invention is simple in structure, low cost, safe, stable, and has high ozone dissolving efficiency, so that it is especially applicable to the household appliances, such as dish washers and washing machines, etc.
