Abstract:
In a rotor for a rotary electric machine, a plurality of magnetic poles are provided in a radially outer portion of the rotor iron core, at intervals in the circumferential direction. Each magnetic pole includes a pair of permanent magnets disposed apart from each other in the circumferential direction, and a magnetic flux-restraining hole that is formed and extended radially inwardly between radially inner end portions of the permanent magnets and that restrains flow of magnetic flux. The magnetic flux-restraining hole is extended so as to project beyond a position of the radially inner end portions to a radially outer side, between the pair of permanent magnets.
Abstract:
A rotary electric machine configured with a stator, rotor, and permanent magnets disposed in an inverted V-shape that becomes gradually narrower from a side of a center of rotation of the rotor. The rotor is provided with a plurality of support portions that extend radially about the center of rotation, and gap portions are respectively formed in correspondence with the plurality of support portions at positions spaced by a predetermined distance from an edge portion of the permanent magnets in a flowing direction of magnetic flux between the permanent magnets and the stator. The gap portions are formed to have such a length that causes magnetic saturation during generation of low torque in a low-current state and that causes no magnetic saturation during generation of maximum torque in a high-current state in which electricity at a high current is supplied to the stator coil.

Abstract:
An iron rotor core includes a first permanent magnet in an outer peripheral portion of the iron rotor core, second permanent magnets on both circumferential sides of the first permanent magnet and arranged in a generally V-shaped configuration opening radially outward, and a first region provided opposite to the first permanent magnet radially inside the region between the second permanent magnets and having a low magnetic permeability. A q-axis magnetic flux path is formed in an iron core region among the first permanent magnet, the second permanent magnets and the first region, and a central portion thereof is formed between the first permanent magnet and the first region, and entrance/exit portions of the q-axis magnetic flux path formed between the second permanent magnets and second regions provided on both circumferential sides of the first permanent magnet and having a low magnetic permeability with generally the same width.
Abstract:
A portable electronic apparatus and a control method of the portable electronic apparatus with excellent operability capable of surely reflecting a user's intended input operation are provided. The portable electronic apparatus and the control method comprise: a first sensor group G1 including a plurality of sensor elements L1 to L4 that are consecutively lined up and arranged and that detect contact; and a control unit 110 that monitors output of the plurality of sensor elements and that executes control based on change in a sensor element that has detected contact, wherein the control unit 110 includes a first contact detection mode for changing from a first state, in which none of the plurality of sensor elements has detected contact, to a second state after detecting that any of the sensor elements has detected contact, changing again to the first state after detecting that a state of none of the sensor elements detecting contact in the second state has continued for a certain time, and executing control according to the change in the contact detection in the plurality of sensor elements occurred in the second state.
Abstract:
A rotating electrical machine that includes a stator formed by winding a coil around a stator core of a substantially cylindrical shape; and a rotor rotatably supported at an inside in a radial direction of the stator, wherein at least one coil end portion in an axial direction of the stator is a curved coil end portion formed to be curved inward in a radial direction of the stator core.
Abstract:
A group communication method in which a communication terminal not participating in the group communication can newly participate in the group communication even while the group communication is being carried out is realized. The group communication method has a personal information management step of managing personal information, a participation request transmission step, a group communication control step, and an other party updating step, in a case where participation intention in the group communication is received from another communication terminal to which no participation request has been transmitted in a state of “party not participating” in which at least one party among the plurality of terminals of the parties sent the participation requests does not participate in the group communication, deleting the party not participating in the group communication from a member list and registering the other party of the other communication terminal in the member list as a party for engaging in the group communication to thereby allow the other communication terminal to participate in the group communication.
Abstract:
A system may include a first communication device, and a recording server. The first communication device may set layout information indicative of a layout of media data. The first communication device may transmit, to the recording server, first media data to be transmitted to the second communication device, the layout information, and first identification information identifying the first communication device. The recording server may store the first media data, the layout information, and the first identification information transmitted from the first communication device. The recording server may receive a request for conference proceedings data from a particular device. The recording server may determine particular layout information for the particular device. The recording server may generate conference proceedings data based on the determined layout information and media data requested by the particular device.
Abstract:
A side collision determination apparatus for a vehicle includes: a first acceleration sensor and a second acceleration sensor mounted on each side surface of the vehicle; and a determination unit configured to perform determination whether a level of collision, which has occurred at apart of the side surface, is equal to or higher than a prescribed level. The determination unit performs the determination based on the acceleration detected by a non-collision side one of the first and second acceleration sensors when the part of the side surface at which the collision has been occurred is adjacent to the sensor-mounted position. The determination unit performs the determination based on the acceleration detected by a collision side one of the first and second acceleration sensors when the part of the side surface at which the collision has been occurred is apart from the sensor-mounted position.
