  • Publication number: 20220144615
    Abstract: A material dispensing device, a material output volume detecting device, and a related damper device for use in an automated beverage preparation apparatus are disclosed. The material output volume detecting device includes: a damper device arranged to operably buffer liquid material flowing therethrough; and a flowmeter arranged to operably measure the flow of liquid material outputted from the damper device. The damper device includes: a damper base having a material entrance hole, a material exit hole, and a material buffer chamber positioned between the material entrance hole and the material exit hole; a diaphragm covered on the material buffer chamber; and a fastening element positioned on the diaphragm and having a hollow portion. When the volume of liquid material within the material buffer chamber exceeds a predetermined amount, the diaphragm deforms to protrude outward, so that a part of the diaphragm enters the hollow portion of the fastening element.

  • Patent number: 11133231
    Abstract: A method for estimating film thickness in CMP includes the following operations. A substrate with a film formed thereon is disposed over a polishing pad with a slurry dispensed between the film and the polishing pad. A CMP operation is performed to reduce a thickness of the film. An in-situ electrochemical impedance spectroscopy (EIS) measurement is performed during the CMP operation by an EIS device to estimate the thickness of the film real-time. The CMP operation is ended when the estimated thickness of the film obtained from the fit parameters of the first equivalent electrical circuit model reaches a target thickness.

  • Patent number: 8737044
    Abstract: A moving module and an electronic device are provided. The electronic device includes a first body, a second body, and the moving module disposed between the first and second bodies. The moving module includes a rail, a moving element, and an elastic element. The moving element is in contact with the rail. The elastic element is connected between the moving element and the first body. When the moving element moves from a first end of the rail to a curved portion of the rail, a force exerted on the elastic element by the moving element is gradually increased. When the moving element passes the curved portion, an elastic restoration force of the elastic element drives the moving element to move toward a second end of the rail. When the moving element reaches the first end or the second end, the first body and the second body interfere with each other.
