  • Publication number: 20200389422
    Abstract: An information processing system that includes an information processing terminal, NFC tag that stores URL information and installation position information, and a server, and the information processing terminal acquires the URL information and the installation position information by reading the NFC tag and transmits terminal position information and the installation position information to the server, and the server determines whether or not the installation position of the NFC tag and the position of the information processing terminal are within a predetermined distance based on the terminal position information and the installation position information transmitted from the information processing terminal, and permits the information processing terminal to use a talk room service only during a predetermined time period in response to determining that the installation position of the NFC tag and the position of the information processing terminal are within the predetermined distance.

  • Patent number: 9287743
    Abstract: Disclosed are a multilayered wound coil, a stator, and a manufacturing method therefor. The stator is provided with: a stator core comprising laminated steel sheets; and a coil which is wound around a teeth section formed on the stator core and has a plurality of layers formed in the circumferential direction of the stator core. The winding of the coil proceeds in either the radial direction or the circumferential direction of the stator core, whichever direction has fewer adjacent conductors, and doubles back at the end in said direction. This reduces the difference in potential between adjacent conductors, making it possible to ensure insulation between adjacent conductors even with a thinner insulating film.

  • Patent number: 9197107
    Abstract: A stator includes: a stator core having a plurality of slots and teeth parts; and coils each formed by winding a flat conductor and disposed in the slots. Of the corners of the rectangular cross-section of the flat conductor, a first corner located on the inner circumference side of the coil when the flat conductor is wound to form the coil is provided with a round chamfer having a radius larger than that of another corner. When the coil is inserted into the slots of stator core elements, the rectangular cross-section of the coil is disposed such that the first corner faces toward the outer circumference side of the stator.
