The invention discloses a threshing device of a combined harvester. The threshing device comprises a threshing barrel and a sieve plate. The sieve plate is matched with the threshing barrel, the threshing barrel comprises a barrel wall, a plurality of rows of threshing columns and first springs, the multiple rows of threshing columns are uniformly arranged along the whole barrel wall, and the adjacent threshing columns are connected with one another by the first springs; the threshing columns comprise static columns and movable columns, the static columns are fixedly arranged on the barrel wall, and the movable columns are axially hinged to the barrel wall; the movable columns comprise first wall outer portions and first wall inner portions, the first wall outer portions are positioned onthe outer side of the barrel wall, the first wall inner portions are positioned on the inner side of the barrel wall, the static columns comprise second wall outer portions and second wall inner portions, the second wall outer portions are positioned on the outer side of the barrel wall, and the second wall inner portions are positioned on the inner side of the barrel wall; the heights of protrusions of the first wall outer portions are higher than the heights of protrusions of the second wall outer portions; the first wall inner portions are separated from the second wall inner portions, andthe adjacent second wall inner portions which are positioned on upstream of the rotation directions are connected with one another by the first springs. The threshing device has the advantages that good threshing effects can be realized by the threshing device, and the threshing device cannot be easily jammed or damaged.

The present invention provides a protective gear for the sacral area, comprising: an upper side belt 1; a lower side belt 2; a pair of back support strips 3; a part 4 of the stitching area of ​​double stitches; elastic foam 5; a fixed adhesive tape 6 , the upper and lower side straps, the back support strip, and the elastic foam are partly connected with the double stitching seam area to prevent them from being separated from each other due to excessive force, and the upper and lower side straps are used to fasten the adhesive tape on the The stitching position of the lower belt keeps the sacrum area protector close to the user's back and sacrum area on the user's abdomen. The arc of the back support bar is roughly consistent with the user's back bending, and the lower belt acts as a rigid support. And make the back support bar fit the user's back and sacrum area, prevent the back support bar from arching when the user squats back, and the elastic foam fits the user's buttocks and sacrum area through the connection with the lower side belt , to provide cushioning when the user squats back on the ground, avoiding or reducing damage to the sacrum area.

The invention discloses a semiconductor structure manufacturing method, which comprises the following steps of: providing a substrate, wherein the substrate is divided into a fuse region with a fuse structure and a bonding pad region with a bonding pad, the fuse structure comprises a first anti-etching layer on a surface layer and the bonding pad comprises a second anti-etching layer on the surface layer; forming a protective layer; forming a photoresist layer on the protective layer, patterning the photoresist layer and forming an opening in the photoresist layer, wherein the opening exposesthe protective layer at a part of a bonding pad position, at a fuse structure position and on the two sides of the fuse structure position; performing primary etching until the first anti-etching layer of the fuse region and the second anti-etching layer of the bonding pad region are exposed at the same time; and performing secondary etching to remote the second anti-etching layer on the surface layer of the bonding pad and the first anti-etching layer on the surface layer of the fuse structure. In the method, a process of performing single photoetching and then sequentially performing the primary and secondary etching is adopted to reduce photoetching times.

The present invention relates to compositions for treating keratinous substrates, such as hair, comprising 3-butoxypropylamine and at least one carboxylic acid; and to systems and methods for treating keratinous substrates with said compositions.

The present invention provides a window covering with a control mechanism for raising and lowering the window covering. The control mechanism provides a separator system. More particularly, the present invention relates to a control mechanism having a separator system that provides a disconnect function to prevent or reduce damage to the control mechanism due to inadvertent force applied to the window covering. The decoupler system has a body movable between an engaged position in which the clutch axle and winding axle move simultaneously, and a disengaged position in which the winding spool It is then independently rotatable relative to the clutch axle.

The embodiment of the invention discloses an anion release unit and an umbrella, and the anion release unit comprises a release device which is set to generate and release negative ions; an adjustingand supporting device which is arranged to support the releasing device and adjust the direction and the height of the releasing device; a storage device which is arranged to be capable of fixing andstoring the adjusting supporting device and / or the releasing device; a release device which is arranged at the first end of the adjusting and supporting device, wherein the second end of the adjustingand supporting device is arranged on the storage device. Through the scheme of the embodiment, omnibearing adjustment of the release device is facilitated, so the release device can be adjusted according to different heights or orientations of human bodies, the adjustment flexibility of the release device is improved, and the storage and protection of the release device are realized.
