20090072657 | ELECTRIC MOTOR AND FUEL PUMP HAVING THE SAME - A permanent magnet has magnetic poles being circumferentially different from each other. An armature is rotatable at a radially inside of the permanent magnet and has a laminated core and a coil. The laminated core includes magnetic plates laminated in an axial direction so as to interpose an insulating layer. The magnetic plates include end magnetic plates located at most distant ends. At least one of the end magnetic plates has an outer circumferential side provided with a collar, which extends in the rotation axis direction so as to be opposed to pole faces of the permanent magnet. The at least one of the end magnetic plates has a thickness t, and the collar has a length h. The thickness t and the length h have a relationship of h/t≦10. | 03-19-2009 |
20090260220 | Fuel pump,motor device for the same, and method for manufacturing the same - A fuel pump includes a pump portion for pumping fuel. The fuel pump further includes a magnet having magnetic poles circumferentially alternate with each other. The fuel pump further includes an armature on a radially inside of the magnet. The armature includes a rotor core provided with a coil formed of a wire. The armature is rotatable for driving the pump portion. A commutator, which is in a substantially disc shape, is provided to an axial end of the armature for rectifying electricity supplying to the coil. The rotor core has an axial end having an outer circumferential periphery defining a commutator-side collar portion extending toward the commutator. The coil is formed by winding the wire between an outer circumferential periphery of the commutator and the commutator-side collar portion. | 10-22-2009 |

20080254821 | Electronic Apparatus - An electronic apparatus includes key operation means, control means, detection means, storage means and memory means. The detection means detects motion of the electronic apparatus. The storage means stores motion identification data obtained from detection data on a motion after a predetermined key operation in the key operation means after predetermined guidance information is outputted or data obtained by computing the detection data, in the memory means. The control means executes the specific process according to the comparison results between detection data obtained by detecting a motion of the electronic apparatus after the motion identification data is stored or data obtained by computing the detection data, and the motion identification data. | 10-16-2008 |
20120278435 | COOPERATIVE OPERATION METHOD, MOBILE COMMUNICATION TERMINAL THEREOF, MAIL TRANSCEIVING METHOD, AND COMMUNICATION SYSTEM - When an application activation instruction is input, it is decided whether the application is expected to access a high-level protection resource or low-level protection resource (step S | 11-01-2012 |

20080299884 | Grinding Wheel - In a grinding wheel in which abrasive tips for rough grinding and abrasive tips for finish grinding are alternately bonded to a periphery of a disk type base rotating about a rotation axis, each abrasive tip includes the abrasive layer for ed by bonding abrasive grains and a lower layer overlaid and integrally for led with the abrasive layer. The abrasive tip is attached to the periphery of the base at the lower layer. A Young's modulus of the lower layer of the abrasive tip for finish grinding relative to a load acting on the grinding surface of the abrasive tip in an inward direction of the grinding wheel is less than that of the abrasive tip for rough grinding. Thereby, the surface of a workpiece can be both rough-ground and finish-ground with superhigh-precision surface roughness with using one grinding wheel | 12-04-2008 |
20100071271 | METHOD FOR MANUFACTURING GRINDING WHEEL HAVING DEPRESSIONS ON GRINDING SURFACE THEREOF - A grinding wheel is manufactured such that (a) any one of particles for an abrasive grain layer and particles for a substrate layer are put into the press-mold die, and other particles are put onto the particles in the press-mold die, and then the substrate layer and the abrasive grain layer are integrally press-molded to form a non-baked grinding chip with an arcuate shape; (b) depressions are formed on the abrasive grain layer of the non-baked grinding chip; (c) the grinding chip on which the depressions are formed is baked; and (d) the plurality of baked-grinding chips are adhered to a core of the grinding wheel. | 03-25-2010 |

20080305726 | WHEEL SPINDLE DEVICE FOR GRINDING MACHINE - In a wheel spindle device wherein a plurality of grinding wheels are attached in a juxtaposed relation to a wheel spindle rotatably carried on a wheel head of a grinding machine, a reference position for specifying a position in the circumferential direction of the grinding wheel is provided on a core member of each of the grinding wheels, and a plurality of inclined grooves at predetermined angular intervals are formed on a grinding surface of each grinding wheel to be inclined relative to the circumferential direction of each grinding wheel. In order that the fluctuations in the dynamic pressure and the grinding resistance between respective grinding wheels and workpiece portions ground therewith do not grow as a combined or synergy effect, the inclined grooves on each grinding wheel are shifted in angular phase from those on another grinding wheel, so that grinding efficiency and accuracy can be enhanced. | 12-11-2008 |
20090088056 | GRINDING WHEEL - In a grinding wheel comprising a disc-like core member and a ring-shape grinding wheel layer wherein superabrasive grains selected from cubic boron nitride particles and diamond particles are contained together with aggregates in a bonding material, the aggregates are made of porous ceramics particles and have an average particle size which is in a range of 70% to 150% relative to the average particle size of the superabrasive grains, and bridges made of the bonding material are formed between the aggregates adjoining to one another or between the aggregates and the superabrasive grains adjoining to the aggregates. | 04-02-2009 |
