A manufacturing method of a thin film transistor having at least a gate electrode, a gate insulation film, an oxide semiconductor layer, a first insulation film, a source electrode, a drain electrode, and a second insulation film on a substrate, including: forming the gate electrode on the substrate; forming the gate insulation film on the gate electrode; forming a semiconductor layer including amorphous oxide on the gate insulation film; patterning the gate insulation film; patterning the oxide semiconductor layer; reducing the oxide semiconductor layer in resistance by forming the first insulation film on the oxide semiconductor layer in the atmosphere not including an oxidized gas; patterning the first insulation film and forming a contact hole between the source electrode and the drain electrode and the oxide semiconductor layer; forming a source electrode layer and a drain electrode layer in the oxide semiconductor layer through the contact hole; forming the source electrode and the drain electrode through the contact hole and allowing the first insulation film to be exposed; patterning the exposed first insulation film and allowing a channel region of the oxide semiconductor layer to be exposed; and increasing the channel region in resistance by forming the second insulation film on the surface including the channel region of the oxide semiconductor layer in the atmosphere including an oxidized gas.

A shank milling cutter includes a cutting portion which is intended to come into engagement with the workpiece, wherein the envelope surface of the cutting portion is substantially cylindrical. At least one major cutting edge is arranged at the peripheral surface of the cutting portion and at least one minor cutting edge (face cutting edge) is arranged at the end face of the cutting portion and with an end diameter D. The minor cutting edge, in projection onto a plane containing the milling cutter axis, has a convexly curved portion with a radius of curvature R>D / 2 and a center of curvature M located such that a distance from the center of curvature M to the axis is in a range from zero to a value smaller than D / 2.

The invention relates to an apparatus and a method for treating a fibrous material web (9) in a paper or cardboard machine in a long nip press unit (29) comprising a press roll (24), which has a rotating press jacket (25) and a mating roll (23), wherein the fibrous material web (9) is dewatered in an extended press nip (26) between the mating roll (23) and the press jacket (25) of the press roll (24). According to the invention, the fibrous material web (9) is guided after the extended press nip (26) on a special rotating press jacket (25) of the press roll (24) to a transfer region (30), in which the fibrous material web (9) is transferred from the press jacket (25) to a transfer element (31, 27). The invention also relates to a pressing apparatus and a method for implementing the same.

The present invention is a solar cell wherein: a diffusion layer of a first conductivity type and a diffusion layer of a second conductivity type are formed on a surface of a substrate, said surface being on the reverse side of a light-receiving surface of the substrate; a first electrode part, a second electrode part, a first electrode line part, a second electrode line part, a first electrode bus bar part and a second electrode bus bar part are arranged; a first insulating film is formed so as to cover the lateral surface part and the upper part of the second electrode part in a region where the second electrode part and the first electrode bus bar part intersect with each other; a second insulating film is formed so as to cover the lateral surface part and the upper part of the first electrode part in a region where the first electrode part and the second electrode bus bar part intersect with each other; the second electrode part is continuously formed in the form of a line immediately below the first insulating film; and the first electrode part is continuously formed in the form of a line immediately below the second insulating film. Consequently, the present invention provides: a back contact solar cell which has low wiring resistance and high conversion efficiency; and a method for manufacturing a solar cell, which is capable of manufacturing such a back contact solar cell at low cost.

An electronic device with grounding structure consists of a conductive load-carry board with a conductive fixing column and a circuit board with a through hole. It is featured as arranging a grounding layer at periphery of said through hole, checking said fixing column into said through hole for fixing said circuit board and connecting said fixing column with said grounding layer.

The fluorescent dye-containing particles contain a porous matrix configured primarily with a metal oxide, an organic fluorescent dye contained in the porous matrix, and a water-soluble polymer contained in the porous matrix. Such dye-containing particles can be manufactured by executing a step in which a dye-containing sol solution that includes a sol solution obtained by hydrolysis of a metal compound, an organic fluorescent dye and a water-soluble polymer is prepared, and a step in which particles are formed from the dye-containing sol solution by means of a spray-dry method.
