  • Publication number: 20190172866
    Abstract: A photosensitive detection unit has a composite dielectric gate MOS-C portion and a composite dielectric gate MOSFET portion. The two portions are formed above a same P-type semiconductor substrate, and share a charge coupled layer. A plurality of the photosensitive detection units are arranged on a same P-type semiconductor substrate in form of an array to obtain a detector. Adjacent unit pixels in the detector are isolated by deep trench isolation regions and P+-type injection regions below the isolation regions. During the detection, the P-type semiconductor substrate in the composite dielectric gate MOS-C portion senses light and then couples photoelectrons to the charge coupled layer, and photoelectronic signals are read by the composite dielectric gate MOSFET portion.

  • Patent number: 10309698
    Abstract: Methods, systems, and apparatuses are described to help manage oil return such as in a chiller system of a HVAC system. A refrigerant/oil mixture can be directed out of the evaporator into an oil return heat exchanger that is configured to help vaporize a refrigerant portion of the refrigerant/oil mixture. Superheat refrigerant vapor can be directed from a condenser into the oil return heat exchanger as the heat energy to vaporize the refrigerant portion in the refrigerant/oil mixture. The oil return heat exchanger can be positioned lower than the evaporator so that gravity can help the refrigerant/oil mixture to flow into the oil return heat exchanger.

  • Publication number: 20050088266
    Abstract: The zero-backflow vent assembly (100) of the present invention prevents backflow into the magnet cryogen vessel (12) and therefore eliminates magnet icing. In general, the present invention employs a spring loaded valve in the magnet vent turret (38) to prevent the influx of air after a magnet quench event. The magnet vent turret (38) is the interface between the liquid helium vessel (12) in the magnet and the atmosphere (40). A vent stack is employed to channel any cryogenic exhaust gas out of the room, normally to the outside atmosphere (40).
