  • Patent number: 10958048
    Abstract: A peeling device (12) includes a first peeling unit (21) and a second peeling unit (22). When an upper peeling die (33) and a lower peeling die (34) of the first peeling unit (21) are moved forward, an insulating coating (8) is peeled off from upper and lower surface of a coil conductor wire (2), and a conductive portion (7) is cut from the upper surface and the lower surface of the coil conductor wire (2). The conductive portion (7) is formed to have exposed portions (7a) and recessed portions (7b) cut in a trapezoidal shape. A front peeling die (42) and a rear peeling die (43) of the second peeling unit (22) are moved downward while the recessed portion (7b) is placed on and pressed against a second receiving section (41b) of a cradle (41), which peels off the insulating coating (8) and cuts the conductive portion (7).

  • Patent number: 10892670
    Abstract: A method for bonding electrical conductors is provided that is capable of suppressing a power source capacity when assembling a stator having a specific structure. First, coil pieces 9 are arranged in contact with bonding portions of a slot coil 5 inserted in a slot of a stator iron core 2 via a metal paste. Subsequently, an electrical current is applied using a pair of electrodes 11A and 11B in the axial direction (upward and downward in the figures) of the slot coil 5 while contact portions 15 between the slot coil 5 and the coil pieces 9 are pressed in an axial direction of the slot coil 5. As a result, electricity flows in the axial direction the coil piece 9 (a direction of an arrow X in the figures).

  • Patent number: 10778072
    Abstract: A control device moves a split claw (11) holding a projecting portion (4d) of an eighth-layer coil segment (4) in a counterclockwise direction D1. At this time, the control device moves first to third extended blades (13a) to (13c) in an outward direction D3 so that the projecting portion (4d) of the eighth-layer coil segment (4) is bent in the outward direction D3. Then, the control device moves the first to third extended blades (13a) to (13c) in an inward direction D4. Through the above steps, the projecting portion (4d) of the eighth-layer coil segment (4) is bent in the counterclockwise direction D1 while being bent in the outward direction D3. As a result, a return force tending to return in the inward direction D4 is generated by an elastic deformation force.

  • Patent number: 10520396
    Abstract: A tire uniformity testing apparatus (1) measures uniformity of a tire (T) by measuring a load generated on the tire (T) pressed against a rotating rotary drum (2). A load model used to control a pressing position of the rotary drum (2) and express a relation between the pressing position of the tire (T) against the rotary drum (2) and a tire load generated in the tire (T) is configured to successively measure the tire load, while changing the pressing position of the tire (T) against the rotary drum (2), and to estimate the tire load using the measured value of the measured tire load.

  • Patent number: 10473556
    Abstract: In a tire uniformity testing apparatus which measures uniformity of a tire by measuring a load applied to the tire pressed against a rotary drum, a load estimation model is generated which is used to control a pressing position of the rotary drum, and generates a load estimation model indicating a relation between the pressing position of the tire with respect to the rotary drum and the load applied to the tire. The load estimation model is generated by: holding the tire in which uniformity has already been measured for each characteristic value; acquiring a nominal model depending on the characteristic value of the tire; and generating based on the acquired nominal model.

  • Patent number: 10379640
    Abstract: Various embodiments provide an electronic pen that ensures security of information, avoids of unnecessary transmission of information, and protects a core body. In one embodiment, the electronic pen includes a core body, a signal transmitter that transmits a signal to a sensor of a position detecting device, a protector that sets at least a tip of the core body to the state of being not exposed to an external environment, and a detector that detects whether or not at least the tip of the core body is in the state of being protected by the protector. A signal including information is allowed to be transmitted from the signal transmitter when at least the tip of the core body is not protected by the protector, and is precluded from being transmitted when at least the tip of the core body is protected by the protector.
