  • Patent number: 10761065
    Abstract: An inspection device inspects a joint-type outer joint member of a constant velocity universal joint that includes a cup section having a bottomed cylindrical shape and track grooves in an inner periphery thereof for torque transmitting elements, and a shaft section extending from a bottom of the cup section. The inspection device inspects the outer joint member, which is obtained through melt-welding on a cup member forming the cup section and a shaft member forming the shaft section. The inspection device includes a surface inspection unit to inspect for a defect which appears on a surface of the outer joint member due to welding, an internal inspection unit to inspect for an internal defect of a welded portion, and a recording unit to record an inspection result of the inspection. The inspection device is configured to efficiently perform in-line total inspection for the melt-welded joint-type outer joint member.

  • Patent number: 8991248
    Abstract: An angular velocity sensor includes a support body, a retaining portion connected to the support body, first to fourth weights, first to fourth arms, a drive unit for driving the first to fourth arms, and a monitor unit for detecting displacements of the first to fourth arms. An X-axis, a Y-axis, and a Z-axis that are perpendicular to each other are defined. The detector unit is symmetrical with respect to both an axis parallel to the X-axis and an axis parallel to the Y-axis. This angular velocity sensor can cancel an undesired signal caused by external disturbances, such as acceleration or impact, thus detecting an angular velocity accurately.
