Abstract: The present invention is related to an extracting method of kuguacin, pharmaceutical composition comprising the kuguacin and use thereof, specifically related to a use of the kuguacin for treating periodontal diseases.

Abstract: A hose and connector assembly includes a connector, a hose having an end portion inserted into the connector and a fastening member mounted in the end portion of the hose and abutting the connector. The connector has a first mounting hole, a mounting hole and a stepped portion located between the first mounting hole and the second mounting hole. The end portion of the hose has a periphery provided with a stop flange abutting the stepped portion of the connector. The fastening member has a periphery provided with a limit flange abutting the stop flange of the hose. Thus, the end portion of the hose is sandwiched between the connector and the fastening member to enhance the combination strength of the hose and the connector.

Abstract: A foldable frame assembly includes a base frame having a wheel-carrying end for mounting a wheel unit, a handgrip end, and an intermediate portion connected to a prop member so as to lift the base frame to a standing position. A tabletop has a front tabletop end pivoted to the intermediate portion for suspending a machine above the ground surface so as to enable a rear tabletop end to turn from a working position to a folded position. A bracing member has an anchoring end pivotally mounted on the wheel-carrying end, and a slidable end coupled with the rear tabletop end such that when the rear tabletop end is turned from the working position to the folded position, the slidable end is turned to be close to the intermediate portion. A rear locking unit is disposed to guard against movement of the slidable end.

Abstract: An embedded type connector comprises a connector main body and at least one embedded socket stage. The connector main body is of hollow shape and has a bottom wall, a left wall, a right wall and a rear wall on inner sides thereof. The left wall and the right wall have two vertically extended insertion grooves and two projecting rails, respectively. The bottom wall has a plurality of terminal holes. The embedded socket stage comprises an insertion plate and a socket mounted on the plate and having a plurality of terminal holes. The insertion plate has dents on both sides thereof with separation same as the rails, The embedded socket stage is inserted into the main body with the dent fitted with the projecting rail and slides downward. In this way, the at least one embedded socket stage can be stacked within the main body.

Abstract: A method for manufacturing trench isolation, comprising firstly, defining a trench isolation over the substrate by photolithography and etching technique. Beside, by way of a spacer fabricating process to form a spacer around each of the two sides of the trench isolation. Therefore, a sharp corner in the crossing region between the trench isolation and an active area adjacent thereto in the substrate is smoothed, and the process window for a sequential gate polysilicon etching is improved, as well as the opportunity to leave polysilicon residue in the corner is eliminated. The short circuit between polysilicon gates is also avoided.

Abstract: The present invention provides a connector assembly composed of two different types of connectors stacked on an upper layer and a lower, respectively. The same connectors are mounted on the same layer and arranged side-by-side. The adjacent connectors are fixed by male mating unit and female mating unit, whereby those connectors can be arranged in stacking and side-by-side manner. Moreover, the connectors of different types are labeled with different color for preventing wrong insertion.

Abstract: A method for fabricating a mixed-mode device. A first gate oxide layer and a second gate oxide layer are formed. The polysilicon layer is used as a mask to pattern the gate oxide layers. Additionally, a top electrode is formed during the first gate oxide layer is patterned. A bottom electrode is formed during the second gate oxide layer is patterned. The first gate oxide layer and the second gate oxide layer are formed by a single oxidation operation, thus thicknesses of the first gate oxide layer and the second oxide layer can be effectively controlled.
