Abstract: An information notification device includes a longitudinal-data storage unit that accumulates, for a plurality of samples, longitudinal data indicating a temporal change in foot size of one sample, a user-data storage unit that stores user data containing a gender, an age, and a past foot size of a prediction target person, a foot-size prediction unit that predicts, based on a current foot size of the prediction target person and the longitudinal data, a change in foot size of the prediction target person in a period from a current point in time to a future point in time, and a notification processing unit that displays, on a display unit, the prediction of the change in foot size of the prediction target person in the period from the current point in time to the future point in time.

Abstract: There is provided a maintenance bypass device capable of achieving safety and efficiency in replacing work of a UPS. The maintenance bypass device (1) is equipped between a power supply (300) and a load device (400) and in parallel with an uninterruptible power supply unit (100), and supplies power from the power supply (300) to said load device (400) when the uninterruptible power supply unit (100) is being detached. In the maintenance bypass device (1), the connection portions (15, 16) of connecting wires (501, 502) connected to the uninterruptible power supply unit (100) are disposed on a front panel (2) disposed on the front side and are a connector type that enables the connection portions (15, 16) to be connected to and disconnected from the connection wires (501, 502) without using a tool.

Abstract: An external connection structure for an electric motor in which basic members are able to be commonly used in an electric fan motor for which either a lead wire or a direct coupler are prepared as an external connection member. Tip end portions of first and third conductor plates and the tip ends of the second and fourth conductor plates are caused to extend between respective brushes which are adjacent to each other in the circumferential direction of the holder stay, and the tip end portions can be made visible through through-holes provided at the body portion of the end cover.

Abstract: A water drain device of a revolving electric machine, wherein an oil reservoir chamber is formed at a position adjacent a bearing housing chamber in a housing having a rotor housing chamber and the bearing housing chamber, a rotor in the rotor housing chamber is supported by bearings in the bearing housing chambers, and an oil seal in slidable contact with the outer peripheral surface of the rotor is provided at a position adjacent the oil reservoir chamber. In the housing, an oil discharge channel opens in a direction in which gravity drains oil in the oil reservoir chamber out of the housing, a water discharge channel connects the rotor housing chamber and the vicinity of an outlet of the oil discharge channel, and an air vent channel connects the rotor housing chamber to the oil discharge channel through the oil reservoir chamber. A drain cover forming a fluid discharge channel is mounted in the vicinity of the outlet of the oil discharge channel and an outlet of the water discharge channel.

Abstract: A brush holder support in a dynamic electric machine such as an electric motor includes an electrically insulating support plate which carries on its one side a plurality of brush holders slidably receiving brushes with pig-tails connected thereto. A pair of conductor plates are secured to the other side of the support plate concentrically with one another. The conductor plates are insulated plate from one another by a portion of the support located therebetween. Each of the pair of conductor plates provides electrical connections between the pig-tails of the brushes of the same polarity. The support plate includes notches formed in its inner and outer peripheral edges so as to provide passages for leading the pig-tails from the one side to the other side of the support plate.

Abstract: A drain cover for covering a pair of draining ports which are formed in the bottom of a cylindrical horizontal yoke of a dynamic electric machine at a distance from each other in the circumferential direction of the yoke.
