摘要： Devices, methods, and processes that improve immunity to transient voltages and reduce parasitic impedances. Immunity to unclamped inductive switching events is improved. For example, a trench-gated power MOSFET device having a SiGe source is provided, where the SiGe source reduces parasitic npn transistor gain by reducing hole current in the body or well region, thereby decreasing the likelihood of a latch-up condition. A trench-gated power MOSFET device having a SiGe body or well region is also provided. A SiGe body reduces hole current when the body diode is turned on, thereby reducing reverse recovery power losses. Other device characteristics are also improved. For example, parasitic gate impedance can reduced through the use of a poly SiGe gate. Also, channel resistance can be reduced through the use of a SiGe layer near the device's gate and a thick oxide region can be formed under the trench gate to reduce gate-to-drain capacitance.

摘要： A process for producing organic peroxide initiators useful in the polymerization of ethylenically unsaturated monomers. The process for making the organic peroxides includes forming an aqueous emulsion of the organic peroxide. The organic peroxide is dispersed as small droplets of from 1 to 10 microns in size in the aqueous emulsion. The organic peroxide may be added to a polymerization reactor containing an ethylenically unsaturated monomer. The organic peroxide functions as a free radical initiator to polymerize the monomer. The organic peroxide may be substantially free of organic solvents and plasticizers. The resulting polymers are of high quality.

摘要： The present invention provides a method and mechanism for optimizing the power consumption of a micro-electronic circuit. According to an embodiment, when optimizing the power consumption of a micro-electronic circuit, one or more candidates for applying one or more optimization techniques may be identified. Then, the one or more candidates may be marked with the one or more optimization techniques within the micro-electronic circuit without altering the data and/or control paths of the circuit. Then, after timing and logic optimization, each power saving technique applied to the one or more candidates may be evaluated to determine whether the technique saves power and/or satisfies the timing requirement of the circuit. Further, each power saving technique applied to the one or more candidates may be evaluated to determine whether the technique is reducible, and if so, then the technique may be reduced to determine whether such reduction improves the circuit's timing.

摘要： Novel polymer stabilizers are disclosed. The novel stabilizers have the general formula (R)qSn-(MR″-OCH2-R′CH]m-OT)4-q, P-[(OCH2-R′CH)mOT]3′ wherein M is O or S and R″is (CH2)pCO-, CO-(CH3)p, or CO(CH2)p-.

摘要： A citrine pleurotus (Pleurotus citrinopileatus) polysaccharide and application thereof are provided, which relate to the field of natural product development and utilization. The citrine pleurotus polysaccharide includes xylose, glucose, galactose, glucuronic acid, fucose, fructose and arabinose. The citrine pleurotus polysaccharide can be applied in preparing drugs for treating sarcopenia caused by cancers. It is demonstrated that the polysaccharide of citrine pleurotus may increase a body weight and a spleen weight, restore morphology, number and density of muscle fibers, reduce inflammatory response and decrease expressions of signature proteins of Atrogin-1 and MuRF-1 for sarcopenia, and alleviate symptoms of tumor-induced sarcopenia in mice with colon cancer cachexia. New effects of polysaccharides of citrine pleurotus are discovered, which provides new ideas for exploitating the citrine pleurotus and treating the sarcopenia caused by cancers.

The imaging beam forming device comprises a wideband transmit unit comprising at least one transmit antenna, a receiver unit comprising at least two receive antennas and at least one receive element that receive radiation from said scene and that generate receive signals from said received radiation, and a beam forming unit that performs beam forming to form a receive beam and obtain beam formed output signals from said receive signals by use of beam forming weights.

摘要： A method for forming a semiconductor structure includes the following steps. Trenches are formed in a semiconductor region using a masking layer such that the trenches have a first depth, a first width along their bottom, and sidewalls having a first slope. The masking layer is removed, and a bevel etch is performed to taper the sidewalls of the trenches so that the sidewalls have a second slope less than the first slope.
