An inner annular backoff demoulding mechanism of an injection mould cavity piece comprises an upper compound plate and a lower compound plate, wherein a cavity is formed in the upper compound plate; a sliding seat is arranged on the lower compound plate; a core is arranged on the sliding seat; a plastic piece is arranged between the core and the cavity; and an inner annular backoff is arranged below the plastic piece. The inner annular backoff demoulding mechanism is characterized in that a support pillar is arranged in the sliding seat; a left oil cylinder, a right oil cylinder, a front oil cylinder and a rear oil cylinder are mounted on the outer side of the sliding seat; a left and right sliding rail and a front and rear sliding rail are formed in the sliding seat; the core comprises a main core and a left inner loose core, a right inner loose core, a front inner loose core and a rear inner loose core which are arranged under the main core; the main core is connected with the support pillar; the left, right, front and rear inner loose cores are matched with the inner annular backoff in the plastic piece; a left groove is formed in the left inner loose core; a left sliding block is arranged below the left inner loose core; the left oil cylinder drives the left sliding block to slide on the left and right sliding rail; a right groove is formed in the right inner loose core; a right sliding block is arranged below the right inner loose core; the right oil cylinder drives the right sliding block to slide on the left and right sliding rail; a front sliding block is arranged below the front inner loose core; the front oil cylinder drives the front sliding block to slide on the front and rear sliding rail; a rear sliding block is arranged below the rear inner loose core; and the rear oil cylinder drives the rear sliding block to slide on the front and rear sliding rail.

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 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 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.
