    摘要： The invention relates to a rotating electric machine including (a) a rotor having a rotating shaft; (b) a bearing for supporting the rotating shaft; (c) a radiation resistant grease applied to the bearing; and (d) a shield layer for shielding the grease from radiation. The shield layer is made of lead and surrounds the bearing. The shield layer includes (1) a first cylindrical shield member that is positioned to cover the bearing, such that the bearing is shielded from a first radiation that is in a direction substantially perpendicular to an axis of the rotating shaft, and (2) second and third disk shield members that are positioned to interpose therebetween the bearing in a direction along the axis of the rotating shaft, such that the bearing is shielded from a second radiation that is in a direction substantially along the axis of the rotating shaft. Thus, the rotor of this rotating electric machine is stably supported in the bearing for a long time even under a highly radioactive environment. That is, the rotating electric machine can be rotated stably for a long time.

    摘要： It is an object of the invention to provide a substrate which allows visual confirmation of the joint state and improvement of reliability of the joint between the components and the substrate to be mounted. The substrate is configured to mount a component having a planer terminal and include a land subjected to solder joint with respect to the terminal of the component.A substrate includes notched portions formed by notching parts of the lands in the direction away from an end surface forming the space. The each land on the substrate includes a first land formed on the substrate and a second land formed of an end surface of the notched portion in the direction of thickness of the substrate. Therefore, visibility of parts of terminals of components is secured utilizing penetration of the notched portions at the time of soldering, so that the joint state of soldering can be visually confirmed.
