摘要:
The disclosure provides a method for treating hepatitis B, including: administering an effective amount of proanthocyanidins wherein the formula of a monomer of the proanthocyanidins is shown as Formula (I): wherein R1 is OCH3, R2 is OH and R3 is H, or R1 is OH and R2 and R3 both are H, or R1 and R2 both are OH and R3 is H, or R1, R2 and R3 all are OH, and R4 is 3-(α)-OH, 3-(β)-OH, 3-(α)-O-sugar or 3-(β)-O-sugar. Bonding between adjacent monomers take place at C4, C8 Carbon-carbon bond or C2, C7 oxygen bond of A type or C4, C8 or C4, C6 Carbon-carbon bond of B type or C type of proanthocyanidins. And the polymerized number is from 2 to 30.

An ultrasonic distance-measuring sensor assembly and an ultrasonic distance-measuring sensor thereof are disclosed. The ultrasonic distance-measuring sensor includes at least two piezoelectric actuators and a member. The member includes a side wall, at least two vibration generating/receiving surfaces and a partition. The vibration generating/receiving surfaces accommodate the piezoelectric actuators as sources. The side wall surrounds the vibration generating/receiving surfaces. The partition is disposed between the vibration generating/receiving surfaces and includes a gap. The gap is disposed between the vibration sending/receiving surfaces.
摘要:
The present invention relates to a heat-conducting module and a method for manufacturing the same. A hollow aluminum tube (110) is put on a corresponding heat pipe (111) to form an aluminum-skinned heat pipe (11). Then, one or more aluminum-skinned heat pipes (11) are disposed in a casting space (22) of a die casting mold (2). Molten aluminum materials are filled in the die casting space (11) of the die casting mold (2) to form a heat-conducting module (1). By using a die casting process, molten aluminum materials are used to cover at least one aluminum-skinned heat pipe (11), thereby finishing the heat-conducting module (1).
