A portable microwave plasma discharge unit receives microwaves and a gas flow via a supply line. The portable microwave plasma discharge unit generates plasma from the gas flow and the received microwaves. The portable microwave plasma discharge unit includes a gas flow tube made of a conducting and/or dielectric material and a rod-shaped conductor that is axially disposed in the gas flow tube. The rod-shaped conductor has an end configured to contact a microwave supply conductor of the supply line to receive microwaves and a tapered tip positioned adjacent the outlet portion of the gas flow tube. The tapered tip is configured to focus the microwaves received from the microwave supply conductor to generate plasma from the gas flow.

A seatback reclining apparatus capable of independently reclining divided seatbacks with different angles. Thereby, interference with a trim of a wheel housing when the seatback is positioned to a flat position is prevented. The seatback includes a reclining shaft provided with a first winding part and a second winding part that is apart from the first winding part with a predetermined distance. The diameter of the first winding part is bigger than that of the second winding part. Around the first winding part, a first spiral spring is provided. The second winding part is provided with a second spiral spring whose number of wounds is greater than that of the first spiral spring.

In one embodiment of the present invention, thermal deformation or bending of membranes in a transition radiation emitting structure can be reduced by providing flex regions in the membranes or the membrane support structures. In a second embodiment, deformation of membranes is compensated for by fabricating the membranes to cooperatively bend in a similar manner and direction. In a third embodiment, deformation of the membrane is reduced by fabricating the membranes with an intrinsic tensile or compressive stress.

The present invention discloses a solid bio-material for the detection of a bio-electromagnetic signal, which senses an information signal generated from living organisms and changes thereof by using fish scale, feathers of fowl and carapaces of tortoises among epidermal tissues of animals having the function of detecting, memorizing and transferring a weak information signal (bio-signal) of an electromagnetic field generated from bio-tissues, and a method for producing the same. The method for producing a solid bio-material for the detection of a bio-electromagnetic signal by using epidermal tissues of living organisms comprises the steps of: immersing the carcass of an animal with a developed epidermis such as fish, fowl, tortoises, etc. in a mixed solution of aromatics (fragrance), salt and water in the ratio of 1:2:300 for one week; separating the epidermis from the immersed living organism; washing the separated epidermis, soaking it in a mixed solution of potassium dichromate, vinegar and water in the ratio of 1:1:100 for 10 to 12 hours, applying a medium pressure thereto for 48 hours under an ambient temperature, and then drying it; applying heat of 40° C. and a cold air of −25° C. temperature in turn to the dried epidermis in a medium pressure state, two or three times in a period of 24 hours each; sterilizing the hot and cold treated epidermis by irradiating ultraviolet rays thereto with a 240 nm ultraviolet lamp for 30 minutes; generating static electricity by putting the sterilized epidermis in an electric cylinder and turning it at 500 RPM; applying pine nut oil to the outer surface of the electro statically processed epidermis; and cutting the epidermis into required sizes.

The present invention discloses method for manufacturing semiconductor device employing an EXTIGATE structure. In accordance with the method, a predetermined thickness of the device isolation film is etched to form a recess. The recess is then filled with a second nitride film. A stacked structure of a barrier metal film, a metal layer and a third nitride film on the second nitride film and the polysilicon film is formed on the entire surface and the etched via a photoetching process to form a gate electrode. An insulating film spacer is deposited on a sidewall of the gate electrode. The exposed portion of the polysilicon film using the third nitride film pattern and the insulating film spacer as a mask to form a polysilicon film pattern and an oxide film on a sidewall of the polysilicon film pattern.

A rotor in an electrical machine, the rotor comprises a magnetic core having at least two poles, a plurality of winding assemblies, one for each pole, and a cylindrical tube enclosing the magnetic core and winding assemblies, the tube including a plurality of rings having different axial widths. Each of the rings is axially spaced apart from an adjacent ring. The respective axial widths of the rings become progressively smaller than the axial width of the ring axially located at or near the center of the tube as the axial distance away from the center of the tube increases. A plurality of winding braces are coupled to at least one of the winding assemblies, the winding braces having different radial heights.
