20160047384 | Device for hydraulically protecting a submersible electric motor of a downhole, preferably centrifugal, pump (variants) - The invention can be used in installations for extracting downhole fluid. The device is in the form of a protector which is arranged between an electric motor and a downhole pump and comprises at least one stage, which comprises a cylindrical body, a tube surrounding the drive shaft of the pump, nipples, a damping bushing, an annular piston in a chamber formed in the space between the body and the tube and dividing the chamber into two sections, which are filled with dielectric fluid and formation fluid, and a formation fluid and dielectric fluid divider which is mounted freely in the chamber at the end of the piston which is in contact with the formation fluid. The divider can move autonomously and is in the form of a single component consisting of two pipe lengths of annular elements which are arranged one in the other and are rigidly interconnected by means of a common base, which is mounted so as to adjoin the ends of the two lengths on the annular-piston side. The annular piston and the divider are mounted in an annular chamber so as to adjoin the internal surface of the cylindrical body and the external surface of the tube with a clearance. The clearance space is filled with a protective medium having hydrophilic properties. The efficiency and operating reliability of the device are increased. | 02-18-2016 |

20080237653 | Deep Implant Self-Aligned To Polysilicon Gate - A CMOS image sensor includes a pinned photodiode and a transfer gate that are formed using a thick mask that is self-aligned to at least one edge of the polysilicon gate structure to facilitate both the formation of a deep implant and to provide proper alignment between the photodiode implant and the gate. In one embodiment a drain side implant is formed concurrently with the deep n-type implant of the photodiode. After the deep implant, the mask is removed and a shallow p+ implant is formed to complete the photodiode. In another embodiment, the polysilicon is etched to define only a drain side edge, a shallow drain side implant is performed, and then a thick mask is provided and used to complete the gate structure, and is retained during the subsequent high energy implant. Alternatively, the high energy implant is performed prior to the shallow drain side implant. | 10-02-2008 |
