  • Patent number: 11846693
    Abstract: A magnetic field calibration device is used to calibrate a magnetism measurement device having a plurality of magnetic sensors and includes a first holder having a first holding surface, a second holder having a second holding surface having a fixed relative positional relation with the first holding surface, and magnetism generating parts fixed to the first holding surface and the second holding surface. Thus, calibration can be completed with a single operation by assigning the first and second holding surfaces of the magnetic field calibration device respectively to the first and second measurement surfaces of the magnetism measurement device. In addition, since the relative positional relation between the first and second holding surfaces is fixed, measurement results obtained from the individual measurement surfaces match each other.

  • Patent number: 10695467
    Abstract: An antibacterial member that maintains a high antibacterial property and a high osteoconductive property for a long duration is provided. The antibacterial member includes a DLC film (F-DLC film) 40 containing fluorine at least partially or entirely on an outermost surface of a base material 10. The F-DLC film has an element ratio (F/(F+C)) of 17% to 72% and a nanoindentation hardness of 2,000 MPa to 16,000 MPa. This maintains wear resistance and close contact, and obtains an antibacterial member that maintains a high antibacterial property and a high osteoconductive property for a long duration. The F-DLC film does not necessarily need to cover the entire outermost surface of the base material but may be disposed in a mottled pattern.
