Abstract: An information processing device includes: a first acquisition unit that acquires authorization omission information being information indicating how many save units among a plurality of save units in which object pieces of an object divided into a division number are stored respectively do not need authorization processing, based on the division number indicating how many object pieces the object is to be divided into and a restoration number being a number of object pieces required to restore the object; and a decision unit that decides a save unit which does not need the authorization processing from among the plurality of save units, based on the authorization omission information acquired by the first acquisition unit.

Abstract: An internal gear 4 is fitted within a housing 2, and a sun gear 6 is disposed inside the internal gear in concentric relationship therewith. A plurality of planet gears 8 are carried by a planetary carrier 10 connected to the housing 2 and are in meshing engagement with the internal gear 4 and the sun gear 6. Washers 16, 18, 20, 22 and 24 are disposed in regions where the members 2, 4, 6, 8 and 10 slide against respectively. Hollow shafts are connected to a coupling 14 which is connected to the inner periphery of the internal gear 4 and to the inner periphery of the sun gear 6, and a drive from an engine which is input to the housing 2 is delivered through the both shafts. A lubricant oil is introduced through the shaft to lubricate sliding parts which are disposed radially outward of the shaft. A perfect lubrication of the interior of the differential gearing is achieved, seizure resistance can be improved and the occurrence of noises can be reduced.
