The invention relates to a solar cell assembly, which comprises a flexible solar cell, wherein the flexible solar cell comprises a first surface for receiving solar radiation energy, and a second surface which is corresponding to the first surface. A shape memory body alloy layer is attached on the second surface, in order to make the flexible solar cell change shapes as the shape changes of the shape memory body alloy layer.

An optical fiber unit for air blown installation includes at least one optical fiber having a core layer and a clad layer, a protective layer coated on the surface of the optical fiber; and protrusions made of polymer resin and formed on the outer circumference of the protective layer in a banded shape. The protrusions may be formed either by supplying polymer resin to the outer circumference of the optical fiber with passing the optical fiber through an extrusion dice in which grooves of a predetermined shape are formed on a hollow inner circumference thereof, or by supplying polymer resin to the outer circumference of the optical fiber through nozzles with moving the optical fiber in a longitudinal direction.

The invention relates to the field of clothes production, in particular to a south exposure type airing frame facilitating taking of fabric. The south exposure type airing frame comprises airing rods, clamping blocks, fixing blocks, a front support and a rear support. Inverted-V-shaped protruding belts are arranged on the top faces of the fixing blocks. The bottoms of the fixing blocks are welded to the top of the front support. The clamping blocks are in L shapes and comprise sliding parts and splicing parts. Inverted-V-shaped sliding grooves are formed in the bottoms of the sliding parts. Through holes are formed in the middles of the sliding parts. Arc protrusions are arranged on the right sides of the sliding parts. The splicing parts are fixed to the left sides of the sliding parts. Arc splicing bars are further arranged on the left side faces of the splicing parts. The airing rods comprise inner rods and sleeve rods. One ends of the inner rods are fixed to the rear support, and the other ends of the inner rods are inserted in the through holes in the middles of the sliding parts. The inner rods are sleeved with the sleeve rods. According to the south exposure type airing frame facilitating taking of fabric, the inclined airing rods arranged side by side are adopted so that all pieces of fabric can receive more sunlight and the fabric can be dried faster; and in addition, each airing rod can be taken off independently, and taking and putting of the fabric are facilitated.

According to a TCON drive circuit applied to a notebook computer, a power supply module, a main control module, a storage module, a brightness adjusting module and an output module are arranged. In the actual application process, due to the fact that the output module comprises the multiple output units, the output units can input processed LVDS signals to the display screen, the display screen can receive more image information, the imaging definition of the display screen is improved, and the resolution of the display screen is guaranteed; besides, the main control module comprises an anti-surge unit, and the anti-surge unit can absorb surge current, so that the circuit is effectively prevented from being damaged by overlarge surge current, and the circuit cannot work normally. Furthermore, due to the arrangement of the brightness adjusting module, when the display screen needs brightness adjustment, the brightness adjusting module outputs related signals to the display screen. The display screen automatically adjusts the brightness.

The present invention discloses a puncture needle sleeve. The puncture needle sleeve comprises a connecting part, a head part, scale marks and a detection part; the connecting part is linear and a radial cross section of the connecting part is circular; the head part is integrally formed with one end of the connecting part and positioned on the same straight line with the connecting part; the scale marks are uniformly arranged on a periphery of the connecting part; and the detection part is arranged on the connecting part. The detection part is arranged on the connecting part close to the headpart, intensity of ultrasonic reflection signals is increased due to the arrangement of the detection part, definition of the puncture needle sleeve in a B ultrasonic image is improved, accuracy andsafety of puncture operation are improved, operation difficulty and risks are reduced, and a puncture success rate of a disposable optimal target point is increased.
