摘要:
Olivine lithium transition metal phosphate cathode materials are made in a microwave-assisted process by combining precursors in a mixture of water and an alcoholic cosolvent, then exposing the precursors to microwave radiation 5 to heat them under superatmospheric pressure. This process allows rapid synthesis of the cathode materials, and produces cathode materials that have high specific capacities.

Electroactive compositions are disclosed for use in lithium ion battery electrodes. The compositions, such as multifunctional mixed metal olivines, provide an electrochemical cell having a plurality of open circuit voltages at different states of charge. The compositions afford improved state-of-charge monitoring, overcharge protection and/or overdischarge protection for lithium ion batteries.

The present invention relates to the manufacture of a novel environmental-protection shoe tree, and particularly to the manufacture of an environmental-protection shoe tree made by molding a primary material of rice husk, in which fibrous plant materials, such as rice husks and wheat husks are sieved and pulverized and are mixed with natural rubber and additives, followed by mechanical mixing to carry out a uniform mixing operation for forming an environmental-protection material block, which is then processed by a rolling machine to uniformly mix with a crosslinking agent and form an environmental-protection material plate, which is then cut into a desired size and put in a mold to be heated and pressurized by a hydraulic machine for performing molding to eventually form a final product of a shoe tree showing characteristics of environmental protection.

摘要:
An environment-conservation rubber shoe sole is made of vegetable fibrous materials including disposed rice/wheat husks, together with natural and synthetic rubbers with suitable amounts of curing additive, activation prompter, and filler, which, after being fully mixed and stirred, are subject to pressurization to form material sheets of suitable thickness for subsequent deposition in a forming mold for curing and molding by heating and pressurizing to complete formation of shoe sole made of environment-conversation material, whereby a de-molded product can be finished with simple trimming whereby low-cost, comfortable, and easy-to-recycle environment-conservation rubber shoe sole can be manufactured and true non-pollution use of shoe sole can be realized.
摘要:
A method of directly and indirectly bonding a microwave substrate 14 and a silicon substrate 12 is described. The method for directly bonding a silicon substrate includes the steps of cleaning the microwave substrate and cleaning the silicon substrate. Then, the microwave substrate and the silicon substrate are stacked together. The stack is placed in a furnace. The temperature of the furnace is increased to a predetermined temperature at a predetermined rate. The temperature of the furnace is reduced at a second predetermined rate. The method of indirectly bonding includes sputtering a silicon dioxide layer on the microwave substrate and silicon substrate prior to placing them together.

A microwave microstrip/waveguide transition structure includes a substrate, an elongated microstrip layer residing on a surface of the substrate, and an elongated integral hollow waveguide on the surface of the substrate. The microstrip layer and a side of the hollow waveguide constitute a single continuous piece of metal. The transition structure is fabricated by providing a substrate, depositing a metallic layer on the substrate, and depositing a metallic hollow housing continuous with a portion of a length of the metallic layer. The metallic hollow waveguide bounded by the metallic layer and the metallic hollow housing and having a contained volume therewithin is thereby defined.

A novel process for the preparation of ultra-fine powders of metal oxide wherein a surfactant is added to the solution for the preparation of the metal oxide to provide nanometer metal oxide powders without the utilization of vacuum or high pressure conditions is disclosed.
摘要:
A microelectromechanical (MEM) device includes a substrate and a flexible cantilever beam. The substrate has positioned thereon a first interconnection line separated by a first gap and a second interconnection line separated by a second gap parallel to the first interconnection line. The substrate also has positioned thereon a first and second primary control electrode wherein one of the first and second primary control electrodes is positioned on one side of one of the first and second interconnection lines and the other one is positioned on the other side of the other first and second interconnection lines. The flexible cantilever beam has a top surface and a bottom surface and a beam width slightly larger than the gap widths at the gaps. A flexible anchor is secured to the bottom surface of the beam at a center of the beam and attached to a center of the substrate so as to position the beam orthogonally to the first and second interconnection lines. Secondary control electrodes are secured to the bottom surface of the beam and positioned opposite the primary control electrodes. First and second contact pads are secured to the bottom surface of the beam and positioned opposite the first and second interconnection lines.
