Patent number: 8937283Abstract: A technique capable of improving the ability to observe a specimen using an electron beam in an energy region which has not been conventionally given attention is provided. This specimen observation method comprises: irradiating the specimen with an electron beam; detecting electrons to be observed which have been generated and have obtained information on the specimen by the electron beam irradiation; and generating an image of the specimen from the detected electrons to be observed. The electron beam irradiation comprises irradiating the specimen with the electron beam with a landing energy set in a transition region between a secondary emission electron region in which secondary emission electrons are detected and a mirror electron region in which mirror electrons are detected, thereby causing the secondary emission electrons and the mirror electrons to be mixed as the electrons to be observed.Type: GrantFiled: April 10, 2009Date of Patent: January 20, 2015Assignee: Ebara CorporationInventors: Masahiro Hatakeyama, Takeshi Murakami, Yoshihiko Naito, Kenji Terao, Norio Kimura, Kenji Watanabe

Patent number: 8865472Abstract: An analyzing device mixes a sample liquid with a reagent by rotation of the analyzing device about a rotation center to generate a centrifugal force. A measurement cell is formed so as to extend in a direction along which the centrifugal force is applied, and a capillary area to which the sample liquid is sucked by a capillary force is formed on one of the side walls of the measurement cell, the side walls being arranged in a rotational direction. The capillary area extends from the outer periphery position to the inner periphery of the measurement cell, thereby reducing the size of the analyzing device. Further, the sample liquid in the measurement cell is sucked to the capillary area by slowing or stopping a rotation, and then the rotation is accelerated to return the sample liquid in the capillary area to the measurement cell.Type: GrantFiled: February 4, 2009Date of Patent: October 21, 2014Assignee: Panasonic Healthcare Co., Ltd.Inventors: Hiroshi Saiki, Kouzou Tagashira, Kenji Watanabe, Kenji Ishibashi, Takuji Miyata

Patent number: 8796599Abstract: An induction heat cooking device is provided that finishes preheating in a short time and maintains the temperature obtained at the finish of the preheating. When a preheating heating mode is selected as an operation mode, a control unit (8) arranged in the induction heat cooking device starts operation in a preheating mode in which a cooking container is heated with a first heating output. When an increment of an output value of an infrared sensor exceeds a first predetermined increment since the heating starts with the first heating output, the control unit causes a notification unit to notify a user that the preheating is finished, and the operation mode is changed to a waiting mode for performing heating with a second heating output that is lower than the first heating output. Further, when the user sets a heating power by means of a heating power setting unit in the preheating mode, the control unit prohibits changing to the heating power set by the user.Type: GrantFiled: February 19, 2009Date of Patent: August 5, 2014Assignee: Panasonic CorporationInventors: Kuniaki Sakakibara, Shintaro Noguchi, Yoshiaki Ishio, Hiroshi Tominaga, Kenji Watanabe

Publication number: 20140158885Abstract: A system for further enhancing speed, i.e. improving throughput in a SEM-type inspection apparatus is provided. An inspection apparatus for inspecting a surface of a substrate produces a crossover from electrons emitted from an electron beam source 25•1, then forms an image under a desired magnification in the direction of a sample W to produce a crossover. When the crossover is passed, electrons as noises are removed from the crossover with an aperture, an adjustment is made so that the crossover becomes a parallel electron beam to irradiate the substrate in a desired sectional form. The electron beam is produced such that the unevenness of illuminance is 10% or less. Electrons emitted from the sample W are detected by a detector 25•11.Type: ApplicationFiled: January 15, 2014Publication date: June 12, 2014Applicant: EBARA CORPORATIONInventors: Nobuharu Noji, Tohru Satake, Hirosi Sobukawa, Toshifumi Kimba, Masahiro Hatakeyama, Shoji Yoshikawa, Takeshi Murakami, Kenji Watanabe, Tsutomu Karimata, Kenichi Suematsu, Yutaka Tabe, Ryo Tajima, Keiichi Tohyama
