20130068624 | ELECTRODEIONIZATION APPARATUS FOR PRODUCING DEIONIZED WATER - An electrodeionization apparatus for producing deionized water comprises a deionization treatment unit including deionization chamber D and a pair of concentration chambers C | 03-21-2013 |
20130241369 | AUTOMOTIVE ROTARY ELECTRIC MACHINE AND WINDING ASSEMBLY MANUFACTURING METHOD THAT IS USED THEREFOR - A winding assembly includes: slot-housed portions housed inside each of the slots of the stator core so as to form pairs that line up in an inner layer and an outer layer relative to a slot depth direction; first return portions at a first axial end of the stator core that link end portions of the slot-housed portions housed in the inner layer inside each of the slots and end portions of the slot-housed portions housed in the outer layer inside the slots that are (N−M) slots away; and second return portions at a second axial end of the stator core that link end portions of the slot-housed portions housed in the outer layer inside each of the slots and end portions of the slot-housed portions housed in the inner layer inside the slots that are (N+M) slots away. | 09-19-2013 |
20140202867 | ELECTRODEIONIZATION APPARATUS FOR PRODUCING DEIONIZED WATER - Provided is an electrodeionization apparatus for producing deionized water, capable of removing or reducing a biased flow of electric current in a deionization chamber. In the electrodeionization apparatus for producing deionized water, at least one deionization treatment unit including the deionization chamber and a pair of concentration chambers adjacent to both sides of the deionization chamber is disposed between a cathode and an anode. In the deionization chamber, anion exchanger layers and cation exchanger layers are stacked in an order in which a last ion exchanger layer through which water to be treated passes is an anion exchanger layer. A bipolar membrane is formed on the cathode side of the anion exchanger layer in the deionization chamber. The anion exchange membrane of the bipolar membrane is in contact with the anion exchanger layer. | 07-24-2014 |
20150137633 | AC GENERATOR - A vehicle AC generator capable of enhancing a cooling effect by increasing an air volume of cooling air is obtained. The AC generator includes: a casing having a ventilation port on an outer periphery; a stator installed in the casing; a rotor supported in the stator in a rotatable manner; a fan installed oppositely to the ventilation port in the casing and rotated integrally with the rotor; and a protrusion formed on a surface of the casing opposing a tip end of the fan at a position adjacent to an outer periphery of the ventilation port of the casing. | 05-21-2015 |

20130154434 | STATOR CORE, MANUFACTURING METHOD THEREFOR, AND ROTARY ELECTRIC MACHINE THAT USES THAT STATOR CORE - The method for manufacturing a stator core includes: a punching step in which magnetic segments are punched out of an electromagnetic steel sheet that is coated with an organic insulating coating; a laminating step in which a laminated body is formed by laminating a predetermined number of the punched magnetic segments; a first preheating step in which a welding position on a wall surface of the laminated body is heated locally from a first end to a second end in a direction of lamination to decompose an organic component in the insulating coating thermally at the welding position; and a first welding step in which the welding position at which the organic component in the insulating coating is decomposed thermally is welded from the first end to the second end in the direction of lamination to interconnect and integrate the laminated magnetic segments. | 06-20-2013 |
20130214634 | AUTOMOTIVE ROTARY ELECTRIC MACHINE AND STATOR MANUFACTURING METHOD THAT IS USED THEREFOR - The stator winding has winding assemblies that are disposed in a stator core so as to be stacked in three or more layers in a radial direction such that slot-housed portions line up in single columns in a clot depth direction inside slots, and radial widths of return portions of the winding assemblies that are mounted so as to be stacked in a radial direction are made sequentially narrower in order of return portions of a winding assembly that is positioned centrally, return portions of a winding assembly that is positioned on an inner circumferential side, and return portions of a winding assembly that is positioned on an outer circumferential side. | 08-22-2013 |
20140354092 | ROTATING ELECTRICAL MACHINE - A cooling fan is provided at an axial end portion of a rotor. The cooling fan generates a cooling air when rotated integrally with the rotor. On a stator core arranged at a position on a radially outer side of the rotor, a plurality of stator coils are arrayed in a circumferential direction of the stator core. Each stator coil includes a coil end that protrudes from an axial end surface of the stator core. A front housing covering the cooling fan includes: an exhaust port for passing the cooling air therethrough, at least part of the exhaust port being located at a position on a radially outer side of the coil end; and a recess portion opposed to the coil end in an axial direction. | 12-04-2014 |
20140354097 | ROTATING ELECTRIC MACHINE - To obtain a rotating electric machine with a simple configuration, including a clearance filling member which can be easily assembled to a bearing housing portion without requiring time and does not adversely affect an outer race of a bearing, provided is an AC generator for a vehicle including a resin case ( | 12-04-2014 |
