Abstract: A rotating electrical machine includes a plurality of core pieces forming a stator core. Each of the core pieces includes contact surfaces on one side end and another side end in a peripheral direction, a tapered protrusion on the contact surface of the one side end, the protrusion including first inclined surfaces outside and inside, and a recess on the contact surface of the other side end, the recess including second inclined surfaces contacting the first inclined surfaces outside and inside to receive the protrusion of adjacent core piece. A cross-sectional shape of the protrusion is a shape such that, inside a circle centered on a first end portion with a distance being a radius between a second end portion located on an opposite side of the first end portion and the first end portion, at least a part of the first inclined surfaces contact the second inclined surfaces.

Abstract: Provided are a feeling share system, an operation device, and a feeling share method which are capable of reproducing a gesture without requiring a user to repeat the gesture. The present invention is provided with: a first operation device including a first operation interface unit that receives an operation from a first user, and a first communication unit that transmits, to a server device, first operation information indicating the operation received by the first operation interface unit; and a second operation device including a second communication unit that receives the first operation information from the server device, a second operation interface unit that receives an operation from a second user, and an operation control unit that reproduces the operation by using the second operation interface unit on the basis of the first operation information received by the second communication unit.

Abstract: According to an embodiment, business processing related to commercial transactions is uniformly supported between a plurality of business entities such as retailers, wholesalers, and manufacturers. A transaction support device generates order information, shipping information, and receiving information, generates profit information indicating a profit of a first business entity based on cash information of the first business entity and the receiving information, generates profit information indicating a profit of a second business entity based on the shipping information of the second business entity, and outputs settlement information containing the profit information to a device of a finance company which acquires the cash sales recovered from the first business entity with respect to a transaction between the first business entity and the second business entity which is an order destination of the first business entity.
