  • Patent number: 11690835
    Abstract: A formulation having excellent gastric protection properties comprises an active pharmaceutical ingredient and a waxy compound, dispersed in a pharmaceutically acceptable oily carrier. The formulation presents a palatable and stable oral dosage form which is particularly suitable for acid-sensitive active pharmaceutical ingredients, and which is also suitable for active pharmaceutical ingredients which are liable to cause stomach irritation.

  • Patent number: 9388811
    Abstract: A micropump structure including a main body, at least one water room partitioning board, at least one fan propeller and at least one drive unit. The main body has at least one water room, an inlet and an outlet. The inlet and the outlet are disposed on a circumference of the main body in communication with the water room. The water room partitioning board is disposed in the water room to divide the water room into at least one water incoming section and at least one water discharging section. The fan propeller is disposed in the water room. The drive unit is disposed in the main body. The water room partitioning board enhances the flow guiding efficiency of the micropump and reduces the axial height of the micropump so that the working efficiency is promoted and less room is occupied.

  • Patent number: 8278796
    Abstract: A fan assembly includes a stator and a rotor. The stator is located in a fan frame and includes a base, at least one magnetizing winding provided on the base at a first relative position relative to a center of the base, and at least one magnetic conductive element provided on the base at a second relative position relative to the center of the base. The rotor is fixedly mounted in a fan hub, and has at least one positive pole and at least one negative pole, which are alternately arranged to constitute a magnetic induction face. The fan hub is rotatably connected to the fan frame via a shaft with the magnetic induction face facing toward the magnetizing winding and the magnetic conductive element on the base. With the above arrangements, the fan can have a largely reduced axial height for use in a limited space.

The fan propeller is disposed in the water room. The drive unit is disposed in the main body. By means of the water room partitioning board, the flow guiding efficiency of the micropump is greatly enhanced and the axial height of the micropump is reduced so that the working efficiency is promoted and less room is occupied.
