  • Publication number: 20200011730
    Abstract: An optical detection sensor is disclosed. The optical detection sensor includes a converter configured to receive non-visible light, convert the non-visible light into visible light, and emit the visible light; and a visible light solid-state image sensor. The converter is located on a light incident side of the visible light solid-state image sensor, and the visible light solid-state image sensor is configured to receive the visible light to generate an electron flow, convert information of the electron flow into data information, and output the data information.

  • Patent number: 10497718
    Abstract: Provided are a silicon-on-insulator structure having bipolar stress and a manufacturing method therefor. The manufacturing method comprises providing a composite substrate, wherein the composite substrate has a silicon substrate layer, a buried oxide layer and a silicon-on-insulator layer sequentially from bottom to top, epitaxially growing a silicon germanium layer on an upper surface of the silicon-on-insulator layer; depositing a hard mask layer to cover a portion of the silicon germanium layer corresponding to an N-type MOS transistor region; depositing a surface oxide layer to cover the silicon germanium layer and the hard mask layer; performing a high temperature annealing treatment so that a portion of the silicon-on-insulator layer corresponding to a P-type MOS transistor region is converted into a silicon-germanium-on-insulator layer, and the portion corresponding to the N-type MOS transistor region is converted into a tensile stress silicon-on-insulator layer.

  • Publication number: 20190131852
    Abstract: A motor includes a stator, a rotor rotatable relative to the stator, a circuit board fixed to the stator, and a heat sink disposed on the circuit board, a side surface of the circuit board facing the heat sink has an insulating region and a metal heat dissipation region without solder mask. The thermal resistance between the circuit board and the heat sink can be reduced by the metal heat dissipation region, thereby improving the heat dissipation of the circuit board.

  • Patent number: 9577502
    Abstract: A transverse flux motor (10) includes a housing (20), a stator (50), and a rotor (30) external to the stator (50) and installed onto the housing. The stator (50) includes a stator sub-assembly including at least one pair of stator core elements (52), each having multiple stator pole teeth (56) circumferentially offset from pole teeth of the other stator core element in the pair. The rotor (30) includes a rotor body (32) made of a single piece part or multiple rotor body laminas (36). The rotor body (32) includes multiple magnetic flux retention features (40) for positioning first magnets (34). Two adjacent magnetic flux retention features (48) define a second magnet retention feature (47) for positioning a second magnet (45) that form a substantially U-shape together with two neighboring first magnets with the same magnetic poles facing each other.
