Abstract: A silicon on insulator (SOI) semiconductor device includes a wire connected to doped regions formed in an active layer of a SOI substrate. A ratio of the area of the wire to the doped region or a ratio of the area of contact holes formed on the wire to the doped region is limited to a predetermined value. When the ratio exceeds the predetermined value, a dummy doped region is added to prevent the device from being damaged during a plasma process.

Abstract: The center of a turntable 30 moves around the central axial line of an autoroation disk 20 along the circular orbit C of a smaller diameter than that of an autorotation disk 20. Thus, the turntable 30 revolves both around a center point O and on its own axis in accordance with an autorotation of the autorotation disk 20. A polishing holder 60 holds a connector of an optical fiber polished by a polishing film 41 arranged on the upper plane of the turntable 30. An optical fiber end face polishing machine provided with a memory 85 for storing a control program which allows a control device 80 to execute predetermined polishing steps, the control device 80 being for controlling an autorotation motor 16 of the turntable 30 and a revolution motor 14 thereof.

Abstract: The gate width of a field effect transistor is increased to a value greater than a size of an active region by forming an inclined portion of a gate electrode. As a result, the current driving capability of a field effect transistor is increased without degrading the integration density. The driving capability of the transistor can be further effectively increased by forming an expanded portion of the active region at a location corresponding to the inclined portion of the gate electrode thereby reducing the resistance of the diffusion layer.

Abstract: While resin forming material and hygroscopic wood flour or wood flour containing water, which were fed to the feed port 23 of the intermeshing type two screw type screw side feeder 20, are being conveyed toward the intermeshing type twin screw extruder 1, they are somewhat kneaded and then introduced into the intermeshing type twin screw extruder 1. Resin forming material and hygroscopic wood flour or wood flour containing water, which have been introduced into the intermeshing type twin screw extruder 1, are melted and kneaded by the heat transmitted from the heating cylinder 2 and also by the heat generated in the process of shearing conducted by the rotating screws 3a, 3b. After that, they are extruded from the die 9 in the form of strands.

Abstract: A water injection foaming devolatilizing method, and an apparatus for practicing the method according to the invention are designed as follows: A molten polymer material is kneaded in a water-injection dispersion zone (11) of an extruding machine having a pair of screws (6) each of which is turned in the same direction. Water is supplied to the molten polymer material, thus the water being dispersed therein while the molten polymer material is kneaded. In a devolatilizing zone (12) downstream of the water-injection dispersion zone, the volatile components in the molten polymer material are removed by being gasified together with the water. In this water injection foaming devolatilizing method, the molten polymer material is smoothly extruded from the filling zone (10) to the water-injection dispersion zone (11), and in the latter zone (11) water injection is performed with increased pressure due to the aid of a ring (15), thereby to achieve the devolatilizing of the molten polymer material.

Abstract: A process and an apparatus for recycling resin scrap including a thermosetting resin paint film and a thermoplastic resin substrate as its major components, wherein the resin scrap is supplied into a passage of a cylinder, melted, and delivered by screw arrays from an upstream side to a downstream side of the passage of the cylinder, and hydrolyzed by a hydrolyzing agent while forming a highly packed region with a resistor. The resistor restricts the resin scrap to flow from the upstream side to the downstream side in a short period of time, and forms the highly packed region where a contact efficiency is enhanced between the resin scrap and the hydrolyzing agent.

Abstract: A low-noise-block downconverter (LNB) for use with flat antennas receiving dual polarized electromagnetic waves includes a body case mounted to a rear side surface of the flat antenna, the body case having two wave guide input ports corresponding to wave guide apertures of the antenna and enclosing a selective device alternatively allowing either one of two outputs corresponding to two different type polarized electromagnetic waves received.
