Abstract: A toilet device includes an electric opening/closing unit including a motor and a transmission mechanism. The transmission mechanism includes an internal gear, a first transmission part and a second transmission part. The first transmission part transmits a rotational force of the motor. The second transmission part transmits a rotational force of the first transmission part. The first transmission part includes a first planetary gear and a first planetary carrier. The second transmission part includes a second planetary gear, a second planetary carrier, and a shaft part. The shaft part revolves around a rotation axis. The first planetary carrier includes a protrusion extends along a trajectory of the revolution of the shaft part. The shaft part contacts the protrusion. A gap is formed between the shaft part and a part of the first planetary carrier other than the protrusion.

Abstract: To provide a system for providing information that allows operators who orally answer questions about certain products from users to deal with the users quickly and effectively. The level of information disclosure is specified for each electronic information to be used for customer support in an information server. In response to the reception of a request for information from an operator terminal, knowledge levels of the user and the operator are determined. The associated electronic information is edited according to rules of providing information that are determined according to the specified knowledge level. The edited version of the electronic information is supplied to the operator terminal. The extent to which information will be disclosed varies according to the level of the knowledge of the user or the operator for a certain product.
