Abstract: The present disclosure provides a method for manufacturing an auto-crosslinked hyaluronic acid gel, comprising conducting auto-crosslinking reaction of a colloid containing hyaluronic acid continuously at low temperature in an acidic environment, and treating the reaction product with steam at high temperature to obtain the auto-crosslinked hyaluronic acid gel with high viscosity.

Abstract: A package structure and the manufacturing method thereof are provided. The package structure includes a first package including at least one first semiconductor die encapsulated in an insulating encapsulation and through insulator vias electrically connected to the at least one first semiconductor die, a second package including at least one second semiconductor die and conductive pads electrically connected to the at least one second semiconductor die, and solder joints located between the first package and the second package. The through insulator vias are encapsulated in the insulating encapsulation. The first package and the second package are electrically connected through the solder joints. A maximum size of the solder joints is greater than a maximum size of the through insulator vias measuring along a horizontal direction, and is greater than or substantially equal to a maximum size of the conductive pads measuring along the horizontal direction.

Abstract: A construction support structure contains: a plurality of first hollow posts, plural second hollow posts, and at least one platform. Each first hollow post includes at least one groove, and each groove has a first width section and a first narrow section, wherein a horizontal width of the first width section is more than the first narrow section. Each second hollow post includes two locking protrusions, and a distance between two sides of each locking protrusion is more than a distance between a top end and a bottom end of each locking protrusion, wherein each locking protrusion has a connecting section, a diameter of which is less than the distance between the two sides of each locking protrusion and the distance between the top end and the bottom end of each locking protrusion, and the connecting section corresponds to the first narrow section of each first hollow post.

Abstract: A riveting tool contains: a body, a retaining post, and a pressing handle. The body includes an extending column, an accommodating cavity for accommodating the retaining post, one of plural adjusting heads selectively fixed into the accommodating cavity. The retaining post includes a movable clamping extension. The body also includes a grip and a returning spring for pushing the grip and the retaining post. The retaining post includes two recessed faces, the pressing handle includes two guiding pieces. Each guiding piece has a neck section, an arcuate section, and a reinforcing section. A curvature of the arcuate section is larger than that of the reinforcing section, such that when a distance between the grip and the pressing handle is expended to a maximum length, each guiding piece retains with the retaining post, and when the pressing handle is pushed toward the grip, each guiding piece pushes the retaining post.

Abstract: A method for producing a cross-linked hyaluronic acid in accordance with the present invention comprises: (a) cross-linking at least one polymer at a temperature, from about 35° C. to about 60° C., for a reaction time of from about 0.1 hour to about 72 hours with a cross-linking agent; and (b) lowering the temperature in step (a) to form about 10° C. to about 30° C. for a reaction time of from about 48 hours to about 28 days to obtain the cross-linked hyaluronic acid, whereby, a cross-linking agent content in a product of the method can be decreased so the product does not require purification.

Abstract: A method for producing cross-linked hyaluronic acid has cross-linking one or more polymers at a low temperature from 10 to 30° C. for a reaction time greater than 48 hours under basic condition with a cross-linking agent to form a cross-linked hyaluronic acid, wherein the polymer is selected from the group consisting of hyaluronic acid, hyaluronate, derivatives thereof and a mixture thereof. Whereby, a cross-linking agent content in a product of the method is decreased so the product does not require purification.
