Patent JP-2003533887-A (JP)
IPC: H01L29/78
Filed: 2001-05-02
Abstract: An extracting transistor (10)-an FET-includes a conducting channel extending via a p-type InSb quantum well (22) between p-type InAlSb layers (20, 24) of wider band-gap. One of the InAlSb layers (24) incorporates an ultra-thin n-type delta-doping layer (28) of Si, which provides a dominant source of charge carriers for the quantum well (22). It bears n<+> source and drain electrodes (30a, 30b) and an insulated gate (30c). The other InAlSb layer (20) adjoins a barrier layer (19) of still wider band-gap upon a substrate layer (14) and substrate (16) with electrode (18). Biasing one or both of the source and drain electrodes (30a, 30b) positive relative to the substrate electrode (18) produces minority carrier extraction in the quantum well (22) reducing its intrinsic contribution to conductivity, taking it into an extrinsic saturated regime and reducing leakage current.

IPC: H01S5/323
Filed: 2002-01-07
Abstract: PROBLEM TO BE SOLVED: To provide an optical functional compound semiconductor superlattice structure, multilayered material equipped with optical functionality and methods of manufacturing the structure and material. SOLUTION: After a substrate 900 is moved to a position above a deposition chamber 300, Ga is caused to uniformly deposit on the surface of the substrate 900 by exposing the surface to Ga for an arbitrary period of time. Then the substrate 900 is moved to a position above another deposition chamber 200 and exposed to NH3 for an arbitrary period of time. When the substrate 900 is exposed to the NH3 , one atomic GaN layer is formed on the AlN of the substrate 900. Then Al is caused to deposit on the substrate 900 by moving the substrate 900 to a position above a third deposition chamber 400 and exposing the substrate 900 to TMA for an arbitrary period of time. In addition, the substrate 900 is again moved to the position above the deposition chamber 200, and the surface of the substrate 900 is again exposed to NH3 for an arbitrary period of time.  When the surface is exposed to the NH3 , one atomic AlN layer is formed on the substrate 900. Thereafter, the optical functional compound semiconductor superlattice structure is obtained by alternately laminating several tens to hundreds of atomic GaN layers and several tens to hundreds of atomic AlN layers upon another by repeating the formation of GaN and AlN in prescribed order.

The other end of the arm supports the bearing of the impression cylinder, and the pressing force of the impression cylinder is generated by the moment of rotation. The strength of the pressing force is determined by adjusting the position of the moving block by transmitting the power of driving of the motor to the linear guide.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2002-02-04
Abstract: <P>PROBLEM TO BE SOLVED: To shorten drawing time without a visual deterioration in displaying a plurality of distant 3D objects in a 3D moving image.  <P>SOLUTION: Simplified models are automatically generated out of 3D models built of detailed polygons, and, as the distance from the viewing point increases, more 3D models are replaced by simplified models though within the limits where no visual deterioration occurs in the rendering process. Farther from the viewing point, simplified models are captured in groups and their images are utilized as textures. Conversion into simplified models or into textures is dynamically and automatically accomplished during the rendering process. In this way, images equivalent to the original 3D models are speedily displayed requiring only the texture mapping time, not dependent on the complexity of the 3D models built of detailed polygons. The method eliminates the unnatural movement of objects always turning to face the viewing point, and produces natural images.  <P>COPYRIGHT: (C)2003,JPO
