  • Transmission system, antenna, control device, and transmission method
    Patent number: 11929771
    Abstract: A transmission system includes: an antenna; a control device including an RF circuit which transmits a first signal for controlling a radio wave to be outputted from the antenna and an external power supply which supplies direct current to the antenna; and a first transmission path which connects the antenna and the control device, and is used in transmission of the first signal and supplying of the direct current to the antenna.

  • Rotary motor and production method thereof, and laminated core production method thereof
    Patent number: 6362553
    Abstract: An object of the present invention is to provide a low cost, high performance, thin structure rotary motor for driving medium used in magnetic disk drive unit, optical disk drive unit or the like, in order to improve the productivity of terminating processing and the reliability of the coils. Magnetic materials which are divided to a plurality of blocks or divided corresponding to respective magnetic pole teeth are connected by means of thin portions. The respective magnetic pole teeth are wound continuously with wire without cutting the wire at the positions in which the thin portions are connected. When a stator is assembled, a plurality of blocks or magnetic pole teeth are disposed on a substrate by separating or bending the thin portions.
