  • Patent number: 10741513
    Abstract: External electrical connectors and methods of forming such external electrical connectors are discussed. A method includes forming an external electrical connector structure on a substrate. The forming the external electrical connector structure includes plating a pillar on the substrate at a first agitation level affected at the substrate in a first solution. The method further includes plating solder on the external electrical connector structure at a second agitation level affected at the substrate in a second solution. The second agitation level affected at the substrate is greater than the first agitation level affected at the substrate. The plating the solder further forms a shell on a sidewall of the external electrical connector structure.

  • Patent number: 10719097
    Abstract: A voltage regulation circuit is suitable to provide an output voltage to a core circuit. The voltage regulation circuit includes a pad, a pull-low unit, a first controlling unit, a second controlling unit and a voltage regulation circuit. The pad receives and provides an input voltage. The pull-low unit generates a pull-low voltage according to the input voltage. The first controlling unit generates a first controlling signal according to the input voltage and the pull-low voltage. The second controlling unit generates a second controlling signal according to the input voltage and the first controlling signal. The voltage regulation unit regulates the input voltage according to the first controlling signal and the second controlling signal, so as to generate the output voltage.

  • Publication number: 20200080463
    Abstract: A vortex generator including an annular bearing for mounting on an interior surface of an exhaust line. The vortex generator further includes an annular blade assembly mounted on the annular bearing. The annular blade assembly includes a leading face with an upstream opening having a first radius. The annular blade assembly further includes a trailing face with a downstream opening having a second radius, wherein the upstream opening and the downstream opening are centered around a longitudinal axis of the exhaust line, and the second radius is different from the first radius. The annular blade assembly further includes a side extending from the leading face to the trailing face, wherein the side has a plurality of openings, each opening of the plurality of openings containing a blade, and each opening of the plurality of openings extends beyond the annular bearing in a direction parallel to the longitudinal axis.

  • Patent number: 8413487
    Abstract: A compressor pressure measuring device drives a compressor to operate for measuring its pressure. A positive pressure pipeline and a negative pressure pipeline are connected to the entry end and the exit end of the compressor, respectively. The positive pressure pipeline and the negative pressure pipeline are provided with an electromagnetic valve, respectively. A control module controls the operation of the compressor and the on/off of the electromagnetic valves in the positive pressure pipeline and the negative pressure pipeline. This automatically detects positive pressure and negative pressure of the compressor.

  • Patent number: 8347690
    Abstract: A compressor leakage detector includes a water tank, an elevator platform, a control panel, and a pressure testing unit. The elevator platform is disposed in the water tank to rise and drop vertically. The operating panel of the control panel has a human-machine interface, indicators, and pressure gauges. The pressure testing unit in the control panel uses an intake pipe to connect to several branch pipes that in turn connect to the compressors in the water tank. Each of the branch pipes connects in series to at least one intake EM valve and at least one exhaust EM valve. A pressure sensor is interposed between the intake EM valve and the corresponding compressor.
