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.

A rotor for a rotary electric machine has a plurality of magnetic poles provided at intervals in a circumferential direction of a rotor core, at an outer periphery of the rotor core. Each of the magnetic poles includes a central magnet, a pair of circumferential-direction magnets disposed on both sides of the central magnet in the circumferential direction such that a spacing between the pair widens towards an outer periphery of the rotor core, and low permeability regions provided in the vicinity of end portions of the central magnet in the circumferential direction, and having a permeability lower than a magnetic material of the rotor core. The rotor core is formed such that a width of a magnetic path entrance portion that is formed between a magnetic-pole inward side face of the circumferential-direction magnet and the adjacent low permeability region decreases towards an outer peripheral face of the rotor core.

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.

The present invention aims at preventing sanitary tissue paper from being torn when it is removed. The purpose is accomplished by sanitary tissue paper of single-ply or double-plies, characterized in that said paper has a lateral tensile strength on a dry condition of 32 N/m or more, a longitudinal tensile strength on a wet condition 32 N/m or more, and a longitudinal tensile strength on a dry condition which is 2.5 to 3.5 times higher than the lateral tensile strength on a dry condition.

A wireless communication device supporting at least non-connection communication and a control method therefore are disclosed. It is determined whether a request for non-connection communication occurs and, when the communication request occurs during an online mode, the online mode is changed to an offline mode in response to occurrence of the communication request, and then the non-connection communication is started. When the communication request occurs, the Auto-Find-IAS function is disabled to prevent undesired connection to another device.

A method of manufacturing a laminated stator core and a laminated stator core manufactured by the method, the method capable of forming a recess 21 over one or both of (a) a lateral portion of an ear piece C of the stator core sheet A to be formed adjacent to the stator core sheet B and (b) a peripheral portion of the annular yoke piece D continuing to the lateral portion, the peripheral portion beside the ear piece C; fitting one ear piece E of the stator core sheet B with a gap in the recess 21; and thereby improving a material yield when the stator core sheets 13 are formed from the strip material 14.

A voltage generating circuit, in which the influence of offset of an amplifier on an output voltage is reduced, has first and second bipolar transistors (Q1, Q2) having emitter terminals at the same electric potential. A base terminal of Q1 is disposed on a collector side of Q2. A first resistance element connects the collector side of Q2 with the base side of Q2; and a second resistance element (R1) connects a collector side of Q1 to R2. A third resistance element (R3) connects a base terminal of Q2 with the electric potential of the emitter terminals. An amplifier (A1) outputs a voltage based on a voltage difference between the collector sides of Q1 and Q2; and a voltage-current converting section (MP1, MP2) converts amplifier output into a current supplied to the connection node of R1 and R2. A voltage is then output on the basis of the generated current.

A stator core includes: an assembled stator core formed of annularly arranged, divided stator cores; a fixing member disposed at an outer circumferential surface of the assembled stator core and capable of pressing the divided stator cores inward in a radial direction of the assembled stator core to annularly arrange and thus fix the divided stator cores; and a weak portion provided between the divided stator cores and the fixing member and deformable by a force exerted from the fixing member to press the divided stator cores.
