Abstract: A speed reducing mechanism according to the present invention includes: a speed reducing unit for decelerating input rotation; an accelerating unit for accelerating rotation output from the speed reducing unit; and a brake unit for applying a braking force for braking the accelerating unit.

Abstract: A robot control system includes circuitry configured to: determine a necessity of assisting a robot to complete an automated work, based on environment information of the robot; select a remote operator from candidate remote operators based on stored operator data in response to determining that it is necessary to assist the robot to complete the automated work; transmit the environment information to the selected remote operator via a communication network; receive an operation instruction based on the environment information from the selected remote operator via the communication network; and control the robot to complete the automated work based on the operation instruction.

Abstract: Drip-proof type electrical rotating machine having inlets and outlets for air flow formed below a rotating shaft supported by a frame. The inlets are formed on end brackets located at both sides of a stator core, and cooling fans rotating together with the rotating shaft are provided on a rotor in opposite to both of the end brackets. Air guides are provided between the inlet and the cooling fans, each air guide being provided with an air passing hole. When the air guide is assembled into the frame, the distance from the axis of the rotating shaft to an above edge of the air passing hole is shorter than the distance from the shaft axis to an lower edge of the air passing hole.
