The invention relates to a vertical cavity surface emitting laser and method for fabricating the same. The vertical cavity surface emitting laser of the invention comprises: a substrate, a first reflector, an active layer, a second reflector, a first electrode layer and a second electrode layer. The second reflector has a first confinement layer with a first aperture and a second confinement layer with a second aperture. The second aperture is smaller than the first aperture. According to the invention, because the second confinement layer is formed by implanting oxygen ion into the second reflector and heating to let the oxygen ion and Al content in the second reflector react to form an oxide layer, the second confinement layer can be used as an optical and electronic confinement layer. Therefore, the width and depth of the second confinement layer can be achieved precisely and easily.

The invention discloses an ultrasonic quilting main machine which comprises a left side box body, a left side plate, a generator support, a right side plate, a right side box body, an edge cutting ultrasonic fixed sliding rail, a fixed lower beam, a cloth trend, a transmission part, a flower roller adjusting part, an ultrasonic part, an edge cutting part and a centrifugal fan. Cloth penetrates in from the upper portion of the first scutching roller from the rear portion from bottom to top, passes through the lower portion of the second scutching roller, the upper portion of the ultrasonic embossing roller, the lower portion of the cloth passing roller, the position between the edge cutting embossing wheel and the second ultrasonic welding head and the position below the first cloth outlet rubber coating roller, and finally penetrates out from the position between the first cloth outlet rubber coating roller and the second cloth outlet rubber coating roller. According to the invention, the use requirement of customers on the edge-cutting welding spots of the cloth finished products is met, and the widths of different cloth finished products are realized by adjusting the position of the edge-cutting part on the guide rail sliding block and the position of the ultrasonic mounting plate II on the edge-cutting ultrasonic fixed sliding rail; and the replacement of the ultrasonic embossing roller is realized by virtue of an auxiliary part, namely the embossing roller replacement support, so that the requirements of different patterns are met.

The invention discloses a die for machining a workpiece. An upper template and a lower template are included and are oppositely provided with an upper die forming block and a lower die forming block correspondingly. The lower die forming block is used for containing the workpiece, the parts, located on the two sides of the lower die forming block, of the lower template are provided with transverseextrusion blocks, and the transverse extrusion blocks are provided with guiding grooves. The upper template is provided with wedge-shaped blocks corresponding to the guiding grooves. When the wedge-shaped blocks downwards stretch into the guiding grooves to slide, the two transverse extrusion blocks oppositely move. When the upper die forming block conducts downward pressing, the wedge-shaped blocks can move along with the upper die forming block, meanwhile, the wedge-shaped blocks can push the transverse extrusion blocks to move, the die can achieve workpiece width finishing and forming simultaneously or sequentially, additional adoption of other dies is not needed, the machining time is shortened, and the production cost is reduced.

A broadband transition structure between a grounded coplanar waveguide and a stripline with a curved ground electrode, comprising: stacked two-layer silicon wafers, uniformly grounded coplanar waveguide units, gradient grounded coplanar waveguide units, and striplines arranged in sequence The unit and the microstrip line unit, the first strip line, the through-silicon via unit and the second strip line connected sequentially inside the gradient ground coplanar waveguide unit and the strip line unit. The invention adopts the grounding electrode whose edge changes in a curve with the width of the equivalent trapezoidal conduction strip, so as to ensure that the characteristic impedance of the gradually changing grounded coplanar waveguide is always the standard impedance; the width and length of the stripline are optimized, so that the equivalent inductance of the stripline and the TSV is equal to the The gap equivalent capacitances are balanced with each other to achieve broadband impedance matching. The device does not need to open a hole on the ground plane, does not increase the complexity of the process, can achieve a large working bandwidth, and meets the requirements of the three-dimensional interconnection network in the silicon-based three-dimensional integrated circuit for broadband and low-loss transmission of radio frequency millimeter wave signals.

The invention discloses a joint production line for a spun-laced nonwoven fabric. The joint production line comprises a placing base plate; one end of the placing base plate is fixedly provided with abox body; a drying device is arranged inside the box body; the two sides of the box body are each provided with an inlet and an outlet; one side of the box body is provided with an air cooling device; the air cooling device is provided with a winding device at one side of the box body; a pressing device is arranged above the winding device; the drying device comprises a fan; one end of the fan isprovided with an air inlet hood; the end of the fan away from the air inlet hood is provided with a communication pipe; the end of the communication pipe away from the fan communicates with a heatingbox; a plurality of heating nets are arranged inside the heating box; and an L-shaped pipe is arranged at one end of the heating box away from the communication pipe. The joint production line has the beneficial effects of being simple in structure and convenient for adjustment, operation and use, reducing the labor intensity of a worker, and greatly improving the work efficiency.

The invention relates to a truck loading pose adjusting device and an adjusting method thereof, and belongs to the technical field of truck pose adjustment. The adjusting device comprises movable platforms, steel wheels and a hydraulic cylinder, wherein the steel wheels are positioned below the two sides of the movable platforms, and the hydraulic cylinder is used for driving the movable platforms; three sets of the movable platforms are arranged, the three sets of movable platforms are located in three pits of the ground respectively, and the distances between the three sets of movable platforms correspond to the intervals between three sets of wheels of the truck respectively; guide rails are arranged below the steel wheels in the pits, the steel wheels slides along the guide rails to achieve the movement of the movable platforms in the width direction, so that the problems that an existing automatic loading system is difficult to accurately place the truck on the loading position and truck position and angle adjustment are encountered during loading are solved, the automation degree of the automatic loading system is improved, the loading efficiency is improved, and the labor cost is saved.
