The invention relates to a gas-turbine combustion chamber with a fuel nozzle comprising a cylindrical nozzle tube (1), into which a fluid is made to flow, and a convexly formed nozzle cover (2), which is arranged downstream of the nozzle tube (1) and has a central point (3), wherein the nozzle cover (2) has a number of through-openings (4a, 4b), through which the fluid that is made to flow into the nozzle tube (1) leaves, wherein the through-openings (4a, 4b) are arranged at different radial distances (R1, R2) from the central point (3) on at least two circular lines (5a, 5b).

PROBLEM TO BE SOLVED: To effectively utilize space by improving layout of a battery for a motor of a motorized two-wheeled vehicle and improve cooling effect of the battery.SOLUTION: A battery assembly body (battery) 26 is disposed by dividing an upper part 27 and a lower part 28. The upper part 27 is disposed on the side part of a head pipe 3 and the lower part 28 is disposed on the side part of a down frame 4. Especially, the lower part 28 is disposed on the outer side than a front fork 7 to approach the vehicle body front part. An inlet port 43 of traveling wind is formed on a cowl in front of the battery assembly body 26. An exhaust port 44 exhausting the traveling wind is provided on an inner cover 42.

The invention relates to the technical field of solar cells, in particular to an efficient all back electrode type solar cell. The solar cell comprises a solar panel arranged on the outer layer, wherein a zigzag stepped surface with long edges and short edges arranged alternately is arranged on the bottom of the solar panel, each long edge is provided with a PN junction diffusion layer and a diffusion layer electrode, and each short edge is provided with a substrate electrode. Due to the fact that the PN junction diffusion layers are arranged on the zigzag long edges, the contact area between a P region and an N region, namely the area of a PN junction region is increased as much as possible. Besides, due to the fact that the substrate electrode layers are arranged on the short edges of the stepped surface, the short edges are arranged to be perpendicular to the surface of the solar panel as far as possible, so that solar rays shining on the solar panel can almost completely shine on the PN junction diffusion layers. In this way, the area of the PN junction diffusion layers can be increased, solar rays can be fully absorbed, sufficient width is guaranteed for the substrate electrode layers, and then the electric generating capacity and conversion efficiency of the solar cell are improved to the greatest extent.

The invention discloses a reciprocating descent control device. A rotating shaft is arranged on a bracket and is provided with a winding drum; a steel wire rope is wound on the winding drum around a pulley; a damping cylinder is arranged on the bracket close to the rotating shaft; a piston of the damping cylinder is connected with the rotating shaft through a crank slider mechanism; and a small hole is formed on the piston. The preferable scheme of the invention is that: the reciprocating descent control device is provided with two damping cylinders, and a rotation angle of the crank slider mechanism which is connected with the damping cylinders is staggered for 90 degrees. Therefore, the dead center of the crank slider mechanism is avoided, the speed is steady during descent control, andthe winding of the steel wire rope due to the speed change is avoided. The reciprocating descent control device is not controlled by a user at all during use, can realize continuous descent control, and has the advantages of steady operation, safety and reliability, and low production cost.

The semiconductor machine bench comprises a printed circuit board with first and second surfaces, a heat source to stable provide heat for the first liquid near circuit board to heat the board, and a regulating device to control the temperature of first surface to under the second surface and make the board deformation achieve rapidly stable state.

The invention relates to a rim for cycles, more particular for bicycles. The invention is also aimed at a tubeless mounted assembly consisting of the said rim and of a tire having in particular two flexible bead wires. According to the invention, the rim consists of two flanges, attached to two seats, intended to receive the beads of a tire, separated from each other by a mounting groove, and, according to the profile of the rim in a radial plane, the bead seats have a generatrix, the axially outer end of which is on a circle of smaller diameter than the diameter of the circle on which the axially inner end is situated, the said generatrix forming an angle with the axis of rotation of the tire of between 15 and 45 degrees.

The invention relates to a glue gun accessory, in particular to a fixed-angle extrusion glass cement glue-flowing tube. The fixed-angle extrusion glass cement glue-flowing tube comprises a casing handle, a top shell, taped fins and a glue outlet, wherein the lower end of the casing handle is provided with the arc top shell which is integrated with the casing handle, the top shell and a positioning plate which is arranged below the top shell and is integrated with the casing handle commonly constitute the half-elliptic glue outlet of which the major axis of section is horizontal; the angle between the positioning plate and the axial lead of the casing handle is 20-45 degrees; and two taped fins which are integrated with the top shell are arranged on the two sides of the top shell and the taped fins are arc shells. The top shell and the taped fins of the invention can be used to extrude glass cement to form the adhesive tape with bowed section, thus further increasing the sealing effectof the glass cement to the joints of the curtain wall.
