  • Patent number: 11969752
    Abstract: The present invention discloses an organic polymer film and a manufacturing method thereof. The organic polymer film is mainly manufactured by the following steps. Firstly, the step (A) provides a xylene precursor and a substrate, and the step (B) places the substrate inside of a plasma equipment. After that, the step (C) evacuates the plasma equipment while introducing a carrier gas which carries vapor of the xylene precursor, and the step (D) turns on a pulse power supply system of the plasma equipment, generating a short pulse for plasma ignition. Finally, the step (E) forms the organic polymer film on the substrate. In the aforementioned steps, the frequency of the short pulse plasma is between 1 Hz˜10,000 Hz, and the pulse period of the short pulse plasma is between 1 ?s˜60 ?s.

  • Patent number: 11944412
    Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

  • Patent number: 10039408
    Abstract: A hanging device with a disposable beverage filter bag includes a filter bag and a hanging ring. The filter bag is made of a filter fabric or filter paper to form a flattened single-opening bag. The filter bag has an opening at an upper end thereof and a pair of hanging slits transversely symmetrically located at middle sections of two sides close to the upper end. The hanging slits are half the width of the opening. The hanging ring is made of a stainless steel wire by winding. The hanging ring has a pair of hanging portions protruding outward from middle sections of two sides of a main frame. When in use, the hanging slits of the filter bag are hanged on the hanging portions of the hanging ring to form a filter stand.

  • Patent number: 9060643
    Abstract: An extraction device is disclosed, mainly including a frame, an elastic fixing ring and a filter. The frame includes a circular opening frame and a lower section formed with a hollowed cup-shaped structure. The filter includes a top section outwardly clamped by the elastic fixing ring to be positioned and clamped outside the filtration stand. The filtration stand includes a downward-bent handle outwardly extended from the frame, and the bottom end of the handle is disposed with an inwardly-bent concave hanging opening, thereby forming a filter stand with a cup-shaped liquid-filtering area. When the filter stand is lifted to be held above a cup opening of the liquid-collecting cup or to be stayed above the liquid-collecting cup, the primary liquid is drained out to downwardly or outwardly flow through the filter to rapidly drop in the liquid-collecting cup, and the residue can be collected in the filter.
