Patent number: 7848481Abstract: In an X-ray CT apparatus, an X-ray source and an X-ray detector mounted in a guide arm are freely movable in such a direction as to approach to and separate from a sample. With respect to this movement, the center of gravity of the whole containing respective constituent elements mounted in the guide arm is kept on the rotational axis by a weight balance adjusting mechanism. The weight balance adjusting mechanism contains a movable weight which is freely movable to the guide arm. The movement of the movable weight is controlled so that a difference between the rotational moment around the rotational axis is offset and substantially equal to zero. The moving passage of the movable weight is set on a straight line which is parallel to the moving direction of the X-ray source and the X-ray detector and does not pass through the rotational axis.Type: GrantFiled: December 19, 2006Date of Patent: December 7, 2010Assignee: Rigaku CorporationInventors: Yuichi Kodama, Ayuta Yamada, Manabu Noguchi

Publication number: 20080036155Abstract: An outer shell member is fixed to the lower end of a rotational shaft so as to wrap around a unit main body from the lower side thereof to the outer periphery thereof. The gap between the rotational shaft and the unit main body is magnetically sealed by a ferrofluid seal portion. A bearing portion is provided at the lower end portion of the unit main body between the unit main body and the outer shell member. Purge gas is supplied to the gap between the rotational shaft and the unit main body at a position nearer to the reaction container than the ferrofluid seal portion and in the neighborhood of the ferrofluid seal portion.Type: ApplicationFiled: December 19, 2005Publication date: February 14, 2008Applicant: Rigaku CorporationInventors: Yasuyuki Shimazaki, Manabu Noguchi
