Abstract: A power conversion device includes a first cooler configured to cool a power module, a second cooler configured to cool at least one electronic component, and a housing configured to house the first cooler and the second cooler. The power conversion device also includes a connecting coolant passage formed in an inner wall of the housing such that the connecting coolant passage connects the first cooler to the second cooler. The power conversion device can have the connecting coolant passage formed in the housing, without enlarging a size of the housing. The strength of a side wall of the housing is enhanced because the connecting coolant passage is formed in the inner wall of the housing.

Abstract: A computing unit computes a computed value for input data. A comparing unit compares the computed value of the computing unit with a computed value of another node which is included in an input/output set. An output unit outputs the computed value as output data of a node itself when the result of the comparison by the comparing unit shows that the computed value matches either one of computed values. When the computed value does not match any one of the computed values of other nodes, a transferring unit adds the computed value of the node itself to the input/output set, and transfers the input/output set to another node.

Abstract: Provided is an imaging apparatus that acquires an object distance to an object and focus position information for each of a plurality of divided areas of an imaging screen corresponding to an imaging area. The imaging apparatus acquires data of the amount of field curvature corresponding to the imaging distance and removes a field curvature component from the object distance and the defocus amount so as to determine a plurality of objects which is equi-spaced from the imaging apparatus and faces the imaging apparatus. When the plurality of objects is equi-spaced from the imaging apparatus and is arrayed so as to face the imaging apparatus, a focused position at which an error in the defocus amount on the entire imaging screen is minimized is calculated. If otherwise, a focusing reference area is selected and then a preferential focusing operation is performed for an object corresponding to the area.
