Patent number: 10644618Abstract: A magnetic levitation device includes a pair of magnets, a displacement detection means, and a control means. The pair of magnets generate magnetic force for supporting a ferromagnet in a noncontact manner. The displacement detection means detect the displacement of the ferromagnet in a lateral shift direction. The control means suppresses the vibration of the ferromagnet in a lateral shift direction. The control means controls the pair of magnets so that a stronger magnetic force acts on the ferromagnet that is displaced in a direction departing from the center of the vibration than when the ferromagnet is displaced in a direction returning to the center of the vibration.Type: GrantFiled: February 23, 2015Date of Patent: May 5, 2020Assignee: NATIONAL UNIVERSITY CORPORATION SAITAMA UNIVERSITYInventor: Takeshi Mizuno

Patent number: 8487253Abstract: An object of the present invention is to provide a scanning electron microscope suitable for monitoring apparatus conditions of the microscope itself, irrespective of the presence of charge-up, specimen inclination, and the like. In order to achieve the object, proposed is a scanning electron microscope including a function to monitor the apparatus conditions on the basis of information obtained with an electron beam reflected before reaching a specimen. Specifically, for example, while applying a negative voltage to the specimen to reflect the electron beam before the electron beam reaches the specimen, and simultaneously supplying a predetermined signal to a deflector for alignment, the scanning electron microscope monitors changes of the detected positions of the reflected electrons of the electron beam. If the above-mentioned predetermined signal is under the condition where an alignment is properly performed, the changes of the detected positions of the electrons reflect deviation of an axis.Type: GrantFiled: November 18, 2011Date of Patent: July 16, 2013Assignee: Hitachi High-Technologies CorporationInventors: Minoru Yamazaki, Akira Ikegami, Hideyuki Kazumi, Manabu Yano, Kazunari Asao, Takeshi Mizuno, Yuki Ojima
