Abstract: The rotary electric machine includes: a rotor core configured having electromagnetic steel sheets; a stator core having electromagnetic steel sheets; a magnet inserted in each of a plurality of through holes; and a magnetic end plate in contact with one or each of an end surface on one side in the axial direction of the rotor core and an end surface on another side in the axial direction of the rotor core, and having a single magnetic sheet or a plurality of magnetic sheets stacked in the axial direction, wherein heat generated from the magnetic end plate owing to eddy current that is generated in the magnetic end plate by magnetic flux from the stator core is equal to or lower than heat generated from the rotor core owing to eddy current that is generated in the rotor core by magnetic flux from the stator core.

Abstract: A welding system includes a tip that biases a welding wire and has a forced power supply mechanism for supplying power to the welding wire at a distal end, a torch including the tip at a distal end, the torch supplying the welding wire toward a welded portion, an automatic machine that holds the torch, and a welding wire straightener attached to the automatic machine, the welding wire straightener correcting a bending tendency of the welding wire.

Abstract: Many actual data 30, each consisting of a set of an actual water distribution amount obtained in advance from a water management system 10 and a variable needed for prediction, are loaded and retained as history data 52, an input space of a case base 54 is quantized according to a desired output allowance error, each history data 52 is set in the quantized input space, and a case representing at least one history data is prepared to generate a case base 52. Then a similar case corresponding to a newly input prediction condition 40 is retrieved from the case base 54, and a water distribution amount corresponding to the prediction condition 40 is estimated from the retrieved similar case.
