Patent number: 8522617Abstract: An acoustic matching device has a water bag (64) that contains water and a water bag support frame (66) that sandwiches and supports the water bag on the left and right sides of the knee and curves along the knee cap. The water bag becomes a plate shape curved along the shape of the water bag support frame, which touches the knee cap and fits the unevenness of the knee. When an ultrasonic probe is moved along the knee cap, the acoustic matching between the knee cap and the ultrasonic probe is obtained.Type: GrantFiled: July 17, 2009Date of Patent: September 3, 2013Assignees: The University of Tokyo, Hitachi Aloka Medical, Ltd.Inventors: Kozo Nakamura, Isao Onishi, Satoru Ohashi, Eiichi Minagawa, Koji Hirota, Ryoichi Sakai, Koji Ogawa, Koichi Miyasaka, Masaru Murashita

Patent number: 8453511Abstract: A mounting unit (16) is aligned by using a mounting unit frame (58) touching the thigh and a knee-contacting portion (62) touching the knee, with the knee being bent. The mounting unit is also equipped with a probe support frame (60) used for moving an ultrasonic probe along the knee cap. The probe support frame moves rotationally about the mechanical center of the knee joint, thereby allowing the ultrasonic probe (78) to move along the knee cap while facing toward the mechanical center of the knee joint and to perform scanning of an ultrasonic beam.Type: GrantFiled: July 17, 2009Date of Patent: June 4, 2013Assignees: The University of Tokyo, Hitachi Aloka Medical, Ltd.Inventors: Kozo Nakamura, Isao Onishi, Satoru Ohashi, Eiichi Minagawa, Koji Hirota, Ryoichi Sakai, Koji Ogawa, Koichi Miyasaka, Masaru Murashita

Patent number: 8384242Abstract: An interconnected system that supplies power to a power system, and includes a power generator that changes in output, and an electric power storage-compensation device. The interconnected system is controlled so that operation of a sodium-sulfur battery that is included in the electric power storage-compensation device and compensates for a change in output of the power generator is stopped, or the interconnected system is set in a non-power transmission mode in which a planned power generation value of a power generation schedule is set to the sum of power generated by the power generator and local load power of the system, when the planned power generation value is 0 kW or less, and the sum of the power generated by the power generator and the local load power of the system has reached a value at which power is supplied to the interconnected system from the power system.Type: GrantFiled: February 28, 2011Date of Patent: February 26, 2013Assignee: NGK Insulators, Ltd.Inventor: Koji Ogawa

Publication number: 20120327909Abstract: There is provided a mobile communication system, a base station, and a method of controlling cell coverage that is capable of operating a mobile communication system such that the cell coverage is maintained approximately and timely at a target level without requiring much labor. In this mobile communication system, a mobile station reports to the base station the position information of the mobile station and the value of reception power of reference signal from the base station. The base station obtains the measured cell coverage as a result of measurement of cell coverage based on the position information and the value of reception power from the mobile stations, and controls at least one of plural parameters including transmission power to the mobile stations, tilt angle of antenna, etc., so as to minimize deviation of the measured cell coverage from the target cell coverage.Type: ApplicationFiled: September 10, 2012Publication date: December 27, 2012Applicant: FUJITSU LIMITEDInventors: Hitoshi Koike, Tohru Nakahara, Koji Ogawa

Patent number: 8333719Abstract: An oscillation arm moves in a seesaw fashion about an oscillation axis which is supported by a support rod and which serves as a fulcrum. A rotation arm and a pressurizer are provided on one end of the oscillation arm. One end of the rotation arm is rotatably attached to the oscillation arm, and a load weight is placed on the other end of the rotation arm. By rotating the rotation arm, the magnitude of a force to be applied by the load weight to the pressurizer is adjusted. More specifically, by displacing the load weight to a predetermined position by rotation and then causing the load weight to stop at this position, a static load corresponding to the rotation angle can be applied to the pressurizer. Further, by causing the load weight to perform rotational motion, the magnitude of the force to be applied to the pressurizer is periodically varied, so that a load which varies periodically can be applied to hard tissue.Type: GrantFiled: March 31, 2008Date of Patent: December 18, 2012Assignee: Hitachi Aloka Medical, Ltd.Inventors: Eiichi Minagawa, Ryoichi Sakai, Koji Ogawa

Patent number: 8317710Abstract: Provided is a bone inspecting system for placing the lower legs (L) of an examinee (P) on a proximal support block (26) and a distal support block (28) mounted on a turning base (24). The proximal support block supports the heads of fibula, and the distal support block supports the lateral malleolus or medial malleolus of a tibial distal end of the examinee. The turning base is supported turnably on a turning axis positioned near the knees of the examinee, with respect to a main base (22), and is moved up and down by an elevating mechanism (30) disposed near the ankles. The turning base (24) is turned by the elevating mechanism while bearing the lower legs thereon, thereby positioning the lower legs horizontally.Type: GrantFiled: July 17, 2009Date of Patent: November 27, 2012Assignees: The University of Tokyo, Hitachi Aloka Medical, Ltd.Inventors: Kozo Nakamura, Isao Onishi, Juntaro Matsuyama, Kenji Tobita, Ryoichi Sakai, Koji Ogawa, Koichi Miyasaka, Eiichi Minagawa

Publication number: 20120234632Abstract: A braking apparatus main body has: a movable body; and an electromagnetic actuator that displaces the movable body in a direction of contact with and separation from a rotating body that is rotated relative to a hoisting machine main body. An adjusting collar is screwed into an adjusting threaded aperture disposed on the electromagnetic actuator. The adjusting collar is disposed between the hoisting machine main body and the electromagnetic actuator. The electromagnetic actuator is mounted to the hoisting machine main body by a mounting device in a state in which the hoisting machine main body bears the adjusting collar. A position of the braking apparatus main body relative to the hoisting machine main body is adjusted in a direction in which a distance between the electromagnetic actuator and the rotating body changes by adjusting an amount of thread engagement of the adjusting collar in the adjusting threaded aperture.Type: ApplicationFiled: February 10, 2010Publication date: September 20, 2012Applicant: MITSUBISHI ELECTRIC CORPORATIONInventor: Koji Ogawa
