Abstract: The present invention provides a multi-phase controlled multi-well pumping unit and relates to an oil exploitation device. The multi-phase controlled multi-well pumping unit includes: a power part, where include a rotating shaft; a crank part, where the crank part includes two crank mechanisms, and a power output part, where the power output part includes a plurality of flexible-power-rope guide components. The pumping unit drives the dual cranks by two ends of the rotating shaft to serve as a power source, and the dual-crank power output mechanism leads out a plurality of groups of flexible power ropes to drive, by using the uniformly distributed guide components, a plurality of pumping wells to operate. Such practice can effectively reduce energy consumption of the multi-well pumping unit system and further improve efficiency.

Abstract: An integrated avalanche photodetector and a method for fabrication thereof. The integrated avalanche photodetector comprises a Ge body adapted to conduct an optical mode. The Ge body comprises a first p-doped region that extends from a first main surface to a second main surface of the Ge body. The Ge body further comprises a first n-doped region that extends from the first main surface towards the second main surface of the Ge body. An intrinsic region occupies the undoped part of the Ge body. A first avalanche junction is formed by the first n-doped region that is located aside the p-doped region. The Ge body further comprises an incidence surface, suitable for receiving an optical mode, and a second n-doped Ge region that covers the Ge body and forms a second avalanche junction with the first p-doped region at the first main surface.
