    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： A dilurea grease composition contains a lubricant base oil and a thickener. The thickener essentially consists of a mixture of at least two diurea compounds each being represented by the following general formula (I) of: ##STR1## wherein R.sub.1 is a difunctional aromatic hydrocarbon residue, and A and B each stands for an amino group represented by the general formula (II) of R.sub.2 --NH--(where R.sub.2 stands for a cyclohexyl group, a group derived from cyclohexyl or an alkyl group) or an amino group represented by the general formula (III) of ##STR2## (where R.sub.3 R.sub.4 each stands for cyclohexyl group or a group derived from cyclohexyl). The ratio in percentage of the numbers of the amino groups (III) to the total numbers of the amino groups (III) plus the amino groups (II) ranges from 1 to 50%. The ratio of the numbers of the amino groups (II) wherein R.sub.2 is a cyclohexyl group or a group derived from the cyclohexyl to the numbers of the amino groups (II) wherein R.sub.2 is an alkyl group ranges from 174 to 4/1.
