Abstract: A method is capable of providing a semiconductor device with a gate having thereon a thicker silicide or metal layer and further having a lower interconnect resistance. The method is further capable of providing the semiconductor device with a polysilicon gate having a recessed tungsten structure for prevention of short circuit between the gate and the drain or the source. For forming a grooved gate structure, a photo-resist is formed on the polysilicon gate before growing on the entire surface of the silicon substrate a silicon dioxide layer. The silicon dioxide layer and the thin gate oxidation layer on drain/source are etched vertically by a reactive ion etching until the photo-resist and the silicon surface of drain/source are exposed. A plurality of spacers are thus formed on the side walls of the photo-resist/polysilicon gate. Upon stripping the photo-resist, the grooved gate structure is formed on the semiconductor device.

Abstract: A class of predominantly hydrophobic non-azo N-substituted 1,8-naphthalimide compounds, each bearing, at its 3-position, a nucleofuge and, at its 4-position, a heteroatomic electron-releasing group. The heteroatomic electron-releasing group is being characterized as having a heteroatom directly linked to the 4-position of the ring, and having at least one hydrogen directly attached to the heteroatom. Upon activation by an activating agent in an environment independent of the presence or absence of oxygen, these compounds generate activated species. The activated species initiate chemical changes in lipid bilayer membranes of viruses and other target cells. These changes can eradicate viruses and other target cells. The activated species can also cause structural changes in lipid and any associated proteins and polypeptides at a level beneath the surface of the membrane, leading to polymerization and crosslinking.

Abstract: A method for stabilize single-stage sigma-delta modulators is disclosed. The method of the present invention employs stability detectors to detect whether the modulator enters the unstable region or not. And internal signal paths that already exist in stable operation are used to recover a unstable modulator to stable region. In the first kind of embodiment, stabilization effect is supported by reduction of effective order. And in the second kind of embodiment, individual instability recovery in each stage in the modulator provide the necessary stabilization mechanism. The present invention can be applied to various configurations, such as multiple feedback and feedforward, and various application, like low-pass and band-pass system.

The method includes the steps of: (1) measuring both the altered modes of vibration with a detector circuit at a selected working point and (2) simultaneously solving for the at least one of pressure and density, the at least one of pressure and density directly determined thereby to allow resulting flow-related signals produced by the meter substantially insensitive to a change in the at least one of pressure and density.

Abstract: A method for preparing a thermoplastic resin composite sheet product reinforced by oriented and discontinuous long fibers comprises a first step in which a plurality of prepreg pieces of a fiber-reinforced thermoplastic resin composite are fed to a horizontal sieve plate in vibration. The prepreg pieces are then caused by the vibration of the sieve plate to fall through the parallel ditches of the sieve plate on a mold plate or thermoplastic resin sheet product located under the sieve plate. The prepreg pieces deposited on the mold plate or thermoplastic resin sheet product are subsequently subjected to heating and pressing such that a thermoplastic resin composite sheet product reinforced by the oriented discontinuous long fibers is formed.

Abstract: The invention relates to a technique called "Internal Linear Feedback (ILF)" for the stabilization of high-order sigma-delta modulators. The ILF technique involves an overload detector and a selector. Once "overloaded" is detected by the overload detector, the selector is activated to make the modulator entering the ILF mode, in which additional internal linear feedback paths are employed to stabilize the modulator. Otherwise, the modulator operates in normal mode as a general high-order modulator.
