  • Photodetector
    Patent number: 10734539
    Abstract: A photodetector is provided with a metal-semiconductor junction for measuring infrared radiation. In another embodiment, the photodetector includes structures to achieve localized surface plasmon resonance at the metal-semiconductor junction stimulated by incident light. The photodetector hence has prompted response and broadband spectra region for photon detection. The photodetector can be used for detecting varied powers of incident light with wavelength from visible to mid-infrared region (300 nm˜20 ?m).
    Type: Grant
    Filed: March 6, 2019
    Date of Patent: August 4, 2020
    Assignee: National Taiwan University
    Inventors: Ching-Fuh Lin, Hung-Chieh Chuang, Meng-Jie Lin, Po-Jui Huang

  • Electromagnetic switch
    Patent number: 6707357
    Abstract: An electromagnetic switch includes an electromagnetic module and a contact module that is to be plugged into the electromagnetic module. The contact module includes a fixed contact member and a movable contact member that is pivoted to the fixed contact member so as to be rotatable relative to the fixed contact member between a first angular position for establishing a first circuit, and a second angular position for establishing a second circuit.

  • Electromagnetic switch
    Patent number: 6661321
    Abstract: An electromagnetic switch includes a socket, an electromagnetic module, and a contact module that is to be plugged into the socket and the electromagnetic module. The contact module includes a fixed contact member and a movable contact member that is rotatable relative to the fixed contact member between a first angular position for establishing a first circuit, and a second angular position for establishing a second circuit. The fixed contact member is formed with conductive blade portions that can be plugged into the socket.
