Abstract: A centrifugal pump includes an impeller and a housing defining a pump chamber that houses the impeller therein. The housing includes an inlet passage in fluid communication with the pump chamber and an outside of the housing. The inlet passage includes a connection passage part having a cylindrical shape extending from the pump chamber and a main passage part having a cylindrical shape connected to the connection passage part, so as to form a bent shape. A central axis of the main passage part is parallel to a reference plane that includes a central axis of the connection passage part. A flow direction of a fluid parallel the central axis of the main passage part is partly the same as the rotational direction of the impeller in a plan view along an axis of the impeller.

The partition supports a bearing for holding a rotation shaft coupled to the rotor and the impeller. The first seal surface and the second seal surface directly hold a seal member therebetween.

The coil terminal extends from the circuit board and is disposed outside or inside the first stator coil in the radial direction. The coil terminal includes a coil-side end positioned further away from the circuit board in the axial direction than at least a portion of the first stator coil. The coil terminal is coupled to the first stator coil via the coil-side end.

Abstract: A value of a current corresponding to a relationship between an illumination intensity instruction value and illumination intensity is calculated based on a previously obtained relationship between a current flowing through a light emitting device and the illumination intensity. A calibration table including the illumination intensity instruction value, the calculated value of the current, and the illumination intensity is created. A required illumination intensity is calculated based on exposure time per frame during autofocusing. An illumination intensity instruction value corresponding to the required illumination intensity is calculated using the calibration table. The calculated illumination intensity instruction value is set using the calibration table such that brightness of a measured image remains consistent even when a frame rate is changed.

Abstract: A layout device that reduces work. The layout device includes a storage unit for storing position information of patterns generated through layout designing. A display unit displays the patterns in accordance with a layout corresponding to the position information. An input unit enables a user to designate a pattern from one of the patterns displayed on the display unit as a marked pattern and enables the user to designate a hierarchical level of the hierarchical structure to which the marked pattern belongs as a reference level. A processing unit, connected to the storage unit, the display unit, and the input unit, obtains coordinates of the marked pattern using the position information of the patterns in the reference level that is stored in the storage unit and dumps the obtained coordinates to the display unit.
