Patent number: 8945303Abstract: The subject is providing a crystallizing device of a biopolymer, which made to form biopolymer crystal efficiently in crystallization solution of a small amount of biopolymers by applying a low voltage and not to make an electrode disturb but observable a state of crystal formation. As an electrode for applying an electric field to a biopolymer solution, a transparent conductor, which does not disturb crystal formation, is used. Between the transparent conductor electrodes 2s, the electric insulating member 4 is placed and the crystallization solution 1 for a small amount of biopolymers is maintained inter-electrode. A biopolymer is efficiently crystallized by applying a low voltage supplied from the voltage generator 5 to the transparent conductor electrode 2. A crystal formation state of a biopolymer is optically observable from the electrode side of a transparent conductor. Orientation control of the biopolymer can be performed by an electric field formed by the above-mentioned voltage application.Type: GrantFiled: February 18, 2010Date of Patent: February 3, 2015Assignee: Institute of National Colleges of Technology, JapanInventors: Takashi Wakamatsu, Yuki Ohnishi

Patent number: 8873139Abstract: A microscope system and observation control method. An electric zoom consecutively changes a magnification for a sample. A revolver includes a plurality of objective lenses of different magnifications and switches the objective lens placed in an observation optical path to intermittently change the magnification for the sample. A control section calculates a total magnification at which the sample is observed based on a magnification provided by the electric zoom and the magnification of the objective lens currently placed in the observation optical path. The control section operates when the revolver switches the objective lens placed in the observation optical path, to determine a target magnification that is the magnification of the electric zoom required to keep the total magnification obtained after the switching of the objective lens equal to the total magnification obtained before the switching of the objective lens.Type: GrantFiled: March 31, 2011Date of Patent: October 28, 2014Assignee: Nikon CorporationInventors: Takashi Wakamatsu, Akitoshi Suzuki

Patent number: 8340464Abstract: In a device for combining a plurality of images having a same photograph range, a position shift between the images having the same photograph range is detected, and the position shift of the images is corrected, and after the position shift is corrected, similarity of the respective portions between the images is evaluated, and the image combining method is changed according to the similarity evaluation. Therefore it is possible to create an image having no position shift due to the shaking of a camera and object blurring due to the movement of the object. Moreover, whether the images are combined or not is determined according to the similarity, hence the processing load is reduced and an image having no object blurring can be created.Type: GrantFiled: March 14, 2008Date of Patent: December 25, 2012Assignee: Fujitsu LimitedInventors: Yuri Watanabe, Masayoshi Shimizu, Kimitaka Murashita, Ayu Miyakawa, Kaoru Chujo, Takashi Wakamatsu
