Patent number: 11443916Abstract: An electron beam system and method are provided. The system includes a detector having a detector face configured to detect back-scattered electrons reflected off of a sample. The system further includes an annular cap disposed on the detector face, and a protective pellicle disposed on the annular cap, covering the detector face. The protective pellicle is transparent to back-scattered electrons and provides a physical barrier to particles directed at the detector face.Type: GrantFiled: March 10, 2021Date of Patent: September 13, 2022Assignee: KLA CorporationInventor: William G.

Patent number: 11395986Abstract: Drying compressed air while utilizing a method for preemptive overload avoidance of moisture to a desiccant bed, including a recovery control process. The method may include a purge means, an initialization period for pre-learning to develop usage-profile log performance summary to compare against real-time data and a protocol for a normal state, a recovery state and a supplemental purge state and means to reestablish normal operations. A procedure for standby and overload alarm alerting states are also described. The purge means may be fixed rate or modulating. The system may have cycle times decrementing or incrementing stepwise in a predetermined or varying time frame to respond to on-going trending data in order to correct imbalance loading conditions by adjusting drying and regenerating cycle times, thus affording a stable delivery of quality dewpoint compressed air to the dryer output.Type: GrantFiled: April 27, 2020Date of Patent: July 26, 2022Inventors: Jeffrey S. Browne, David R. Arno, John A. Carlin, Jeffrey G. Ewers, William G. Schultz, III

Patent number: 5362964Abstract: An environmental scanning electron microscope which achieves image resolution comparable to that of a conventional SEM. A biased ring electrode which detects secondary electron signals emanating from the surface of the specimen is provided in the specimen chamber. A biased pressure limiting aperture electron detector is also provided to reduce signals emanating from backscattered electrons and to reduce signal noise generated by the electron beam. This environmental SEM also optimizes the signal amplification of the secondary electrons following detection thereof, such that the detector noise is reduced below the noise in the signal itself, while still maintaining an overall bandwidth that is suitable for setting up the image. An optical window system is also provided in this environmental SEM which allows the user to easily switch between the normal environmental SEM electron image (limited to 0.5 mm in diameter) to an optical light view of the sample that covers a field-of-view of up to about 7 to 10 mm.Type: GrantFiled: July 30, 1993Date of Patent: November 8, 1994Assignee: ElectroScan CorporationInventors: W.

Patent number: 4463780Abstract: There is disclosed an elbow cover formed of a flexible thin sheet having a bistable configuration with: (1) an open stacking shape having an interior concavity and exterior convexity formed with a substantially ellipsoidal central portion and opposite, laterally projecting, substantially parabolic hyperboloidal ears; and (2) a closed, stable configuration forming a tubular elbow shape with the ears folded inwardly, completing the tubular ends of the elbow shape. The elbow cover is characterized by an unstable configuration assumed by compression of the closed tubular shape between its opposite outside tubular edges whereby the elbow shape flexes and spreads open, laterally separating the ears in a position permitting a one-handed application of the cover to an insulated elbow joint of tubular conduits.Type: GrantFiled: April 23, 1982Date of Patent: August 7, 1984Inventors: Roland P.
