Abstract:
A biosensor for quantifying an analyte in a sample and usage thereof are provided. The biosensor includes an insulative substrate, a cover, a sample supply port, an electrode system including at least a working electrode, a counter electrode and a third electrode, and a reaction layer at least formed over the working electrode. The third electrode, used for estimating whether the amount of the sample is sufficient, is disposed nearer to the sample supply port than the counter electrode is. Whether the amount of the added sample is sufficient is estimated by comparing the electrical current value detected between the working electrode and the counter electrode with the electrical current value detected between the working electrode and the third electrode. This invention has a simple structure and produces accurate measurements.
Abstract:
Method for preparation of anode film for thin film battery comprises: providing a target material to provide Li ion and Ti ion and a substrate comprising a base layer, a buffer layer and a precious metal current collector layer; sputtering LiMO layer on a said substrate at high temperature in a vacuum chamber and obtaining the anode film for thin film battery of this invention. In this invention, material for the precious metal current collector may be a precious metal such as Ag, Au, Pt etc., the alloy and oxides of these metals. The sputtering temperature may be above 300° C., preferably above 500° C. and most preferably above 650° C. The anode thin film material so prepared may be Li4Ti5O12. This invention also discloses anode film so prepared and thin film battery using such anode film.
Abstract:
An improved motor housing with a slop structure at one side of the housing, the slot structure is arranged with ledges along its outer edges in which several threaded holes are provided for placing bolts through which clamping level of the outer body can be controlled so that a stator core can be inserted or removed easily and repeatedly, resulting in low cost, simplified assembling process, and facilitating modification and test of a motor in the development stage in research institutions.
