Patent number: 9257266Abstract: In a micro-channel plate, an electron emission film and an ion barrier film formed on a substrate are integrally formed by the same film formation step. In this structure, the electron emission film and the ion barrier film are made as continuous and firm films and the ion barrier film can be made thinner.

Patent number: 8999183Abstract: A method involving ion milling is demonstrated to fabricate open-nanoshell suspensions and open-nanoshell monolayer structures. Ion milling technology allows the open-nanoshell geometry and upward orientation on substrates to be controlled. Substrates can be fabricated covered with stable and dense open-nanoshell monolayer structures, showing nanoaperture and nanotip geometry with upward orientation, that can be used as substrates for SERS-based biomolecule detection.Type: GrantFiled: September 10, 2012Date of Patent: April 7, 2015Assignees: IMEC, Katholieke Universiteit Leuven, K.U. Leuven R&DInventors: Willem Jozef Katharina Van Roy, Jian Ye, Pol Van Dorpe

Publication number: 20150084726Abstract: An example variable reluctance device includes a load structure connected to an armature through a connecting arm. The armature is positioned between two oppositely oriented core structures. A structural frame secures the core structures in a fixed position, forming gap regions between the core structures and the armature, forming a magnetic circuit. The armature is resiliently centered between the core structures by a spring, such that the gaps and are approximately equal in width when the armature is at rest. The device further includes a magnetic substance within the gaps that is compressed or stretched to allow movement of the armature.Type: ApplicationFiled: August 26, 2013Publication date: March 26, 2015Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventor: George David Goodman
