Patent number: 8975893Abstract: In a method for optimization of a flow coding with switching of an additional bipolar dephasing gradient pair, used in a magnetic resonance (MR) phase contrast angiography, the strength of the flow coding is selected depending on the flow velocity in the vessels that should be depicted. MR signals of an examination region are acquired with continuously running overview measurements, with an operator-selected flow coding strength. After the selected flow coding strength is adopted automatically for the next measurement of the continuously running overview measurements, and two partial measurements with different flow codings are implemented for each selected strength and a phase difference image from the two partial measurements is calculated and depicted in real time, and the selected flow coding strength is automatically adopted for the MR phase contrast angiography.Type: GrantFiled: April 20, 2012Date of Patent: March 10, 2015Assignee: Siemens AktiengesellschaftInventors: Andreas Greiser, Peter Speier

Patent number: 8621659Abstract: In a method of manufacturing this cantilever for the magnetic force microscope, a magnetic film is formed on a probe at a tip of the cantilever for the magnetic force microscope. When a non-magnetic rigid protective film is formed around the probe, the film is formed from the front of the probe of the cantilever for the magnetic force microscope at an angle (15° to 45°) and from the back of the probe of the cantilever for the magnetic force microscope in two directions each at an angle in a range of (15° to 30°).Type: GrantFiled: May 3, 2012Date of Patent: December 31, 2013Assignee: Hitachi High-Technologies CorporationInventors: Kaifeng Zhang, Takenori Hirose, Masahiro Watanabe, Tetsuya Matsui, Tsuneo Nakagomi, Teruaki Tokutomi

Patent number: 8606376Abstract: A method of actuating a system comprising a movable component and an actuator configured to move the movable component comprises providing a control signal representative of a desired motion of the movable component. The control signal is supplied to one or more resonators. Each of the one or more resonators has a mode of oscillation representative of at least one elastic mode of oscillation of the system. The control signal is modified by subtracting from the control signal a signal representative of a response of the one or more resonators to the control signal. The actuator is operated in accordance with the modified control signal. Thus, undesirable elastic oscillations of the system which might occur if the system were operated with the original control system can be reduced.Type: GrantFiled: October 7, 2009Date of Patent: December 10, 2013Assignees: Mitutoyo Corporation, Bundesrepublik Deutschland, Endvertreten Durch den Präsidenten der Physikalisch-Technischen BundesanstaltInventors: Hartmut Illers, Kazuhiko Hidaka, Akinori Saito, Hans-Ulrich Danzebrink

Patent number: 8359661Abstract: Applying an alternating current to a magnetic head as a sample generates an alternate-current magnetic field from the sample. A cantilever includes a probe that is made of a magnetic material or is coated with a magnetic material. The cantilever is displaced when it approaches the sample. Detecting the displacement of the cantilever detects distribution of the magnetic field from the sample. It is possible to fast measure distribution of the magnetic field generated from the sample when a frequency of the alternating current applied to the sample differs from a resonance frequency of the cantilever.Type: GrantFiled: December 30, 2009Date of Patent: January 22, 2013Assignee: Hitachi High-Technologies CorporationInventors: Takehiro Tachizaki, Masahiro Watanabe, Hideaki Sasazawa, Minoru Yoshida, Tsuneo Nakagomi, Teruaki Tokutomi
