Abstract:
Methods for sequencing nucleic acids are presented. Sequencing is accomplished through the chemical amplification of the products of DNA synthesis and the detection of the chemically amplified products. In embodiments of the invention, a substrate is provided having a plurality of molecules of DNA to be sequenced attached and a plurality of molecules capable of chelating pyrophosphate ions attached, the DNA molecules to be sequenced are primed, and a next complementary nucleotide is incorporated and excised a plurality of times leading to the buildup of pyrophosphate ions locally around the DNA molecule to be sequenced. Pyrophosphate ions are captured by the substrate-attached chelators and optically detected to determine the identity of the next complementary nucleic acid in the DNA molecule to be sequenced.

Provided is a cap assembly for use in cylindrical lithium ion batteries. The cap assembly includes an insulating gasket defining a through hole therein, a rupture plate positioned in the through hole, a vent plate soldered on and electrically connected to the rupture plate, a current interrupt device positioned on the rupture plate, and an end cap assembled on the current interrupt device. The current interrupt device can cut off the current path when the battery discharges at a high discharge rate, so as to improve the safety performance of the lithium ion battery.
Abstract:
An electrode group is configured for use in a lithium ion battery. The electrode group includes an anode plate and a cathode plate wound with a separator interposed therebetween. At least one metal oxide layer is disposed between the anode plate and the cathode plate. The metal oxide layer is provided at two length edges of the anode plate and/or the cathode plate, corresponding to the cutting edge of the cathode current collector where the cut burr formed in cutting process. Even though the cut burrs can pierce through the separator, the cut burrs still cannot contact the anode film. Any internal circuit short, caused by contact between the aluminum foil and the anode film, may therefore be avoided and, therefore, the performance of the lithium ion battery is remarkably improved.

A system and method for an improved magnetic head arm assembly (HAA) is disclosed. The HAA includes three principal components, a head gimbal assembly (HGA), a flexible printed circuit (FPC) assembly, and an actuator coil assembly. The design allows for HAA rigidity, yet each of the components is designable and manufacturable independent of one another, in addition to other advantages over current methods.

Abstract:
The measuring system generates a temperature difference between a heating terminal and a terminal conductive device by setting the temperature of a metal heated block at the heating terminal and the temperature of a heat dissipating water jacket at a heat dissipating terminal, and judges the thermal conductive capability of the thermal conductive device by comparing the cooling speed of the metal heating bock to obtain a relative power value according to the variation of heat quantity of the metal heated block in practical temperature reduction process. The maximum thermal conductive quantity (Qmax value) of the thermal conductive device can be rapidly obtained by parameter conversion with respect to the maximum power value. In the case of confirming the cooling curve (cooling speed) of a standard sample, the object of screening the thermal conductive efficiencies of the thermal conductive devices can be achieved by using the cooling curve.
