  • Patent number: 10634647
    Abstract: An abnormal noise detection method of a steering system is configured to detect an abnormal noise from the steering system. The steering system includes a column shaft configured to rotatably support a steering wheel and is configured to steer a wheel in response to rotations of the column shaft. The method includes measuring a sound from an end portion of the column shaft on a steering wheel-side by using a microphone arranged to face the end portion of the column shaft, and generating an abnormal noise detection signal due to the steering system from a sound signal to be output from the microphone.

  • Publication number: 20200124499
    Abstract: An information terminal is configured to extract a predetermined frequency band from a waveform of a signal of a machine component detected by a vibration sensor, to compare an analyzed frequency component and a damaging frequency resulting from a damage of the machine component, and to diagnose abnormality of the machine component. The information terminal includes a database in which the damaging frequency resulting from the damage of the machine component is preserved as a converted damaging frequency obtained by converting the damaging frequency on a basis of a predetermined rotating speed of the machine component. The damaging frequency is provided by calculating the converted damaging frequency in the database by using an actual rotating speed of the machine component. Accordingly, it is possible to keep specifications of a machine component confidential without preserving the specifications of the machine component.

  • Patent number: 10559417
    Abstract: A coil component in which a change in thicknesses of the winding part is prevented is provided. According to the coil component, since each of a pair of neighboring resin walls and a seed part between the pair of resin walls are separated by a predetermined distance, a plating part grown on the seed part is easy to grow uniformly between the pair of neighboring resin walls. For this reason, the winding part whose surface is gentle and in which a change in thickness is prevented is obtained by plating growth.

  • Publication number: 20190377684
    Abstract: A storage control system reads a data set from a storage apparatus if necessary in response to an I/O request. A data set contains data and an address. The storage control system performs an all-type address check which is a check to determine whether one of a first address and second address which correspond to a read-target data set in address translation information, which is information indicating a mapping relationship between one or more first addresses and one or more second addresses, matches the address among the data and address contained in the data set. The one or more first addresses are each an address which belongs to the first address type. The one or more second addresses are each an address which belongs to the second address type. The storage control system performs processing according to the I/O request when the result of the all-type address check is true.
