  • Publication number: 20200238768
    Abstract: A pneumatic tire 1 comprises a carcass 6 extending between bead cores of bead portions via a tread portion 2 and sidewall portions, and a belt layer 7 arranged on an outer side in a tire radial direction of the carcass 6 and inside of the tread portion 2. The pneumatic tire 1 further comprises a damping rubber body 30 arranged between the carcass 6 and the belt layer 7, and a noise damper 20 arranged on an inner cavity surface of the tread portion 2. A width W1 in a tire axial direction of the damping rubber body 30 is in a range of from 60% to 130% of a width W2 in the tire axial direction of the belt layer 7, and a water absorption rate of the noise damper 20 is in a range of from 10% to 25%.

  • Publication number: 20200208635
    Abstract: A seal member includes pushing projections that project from a seal body toward at a groove inner-side circumferential surface and are arranged at intervals in a circumferential direction of the seal body. The pushing projections push the seal body against the groove inner-side circumferential surface and a groove outer-side circumferential surface between the groove inner-side circumferential surface and the groove outer-side circumferential surface. This reduces the gap between the groove outer-side circumferential surface and the seal member in the seal accommodating groove. Thus, salt water is unlikely to collect in the gap between the groove outer-side circumferential surface of the seal accommodating groove and the seal member. This improves the corrosion resistance of the housing and the seal member.

  • Patent number: 10297039
    Abstract: With a recognition device of the present invention, when a target component that is an imaging target is moved in a direction from one to another of an upper limit imaging position and a lower limit imaging position, a protruding section of the target component is imaged at each of a predetermined pitch (0.1 mm). Then, it is determined whether it is possible to recognize the position of the protruding section of the target component based on image data of each pitch (O: recognition possible, X: recognition not possible). Here, from among imaging positions (H4 to H10) according to image data for which it was determined to be possible to recognize the position of the protruding section of the target component, a position (H7) that is at a central point between a position closest to the upper limit imaging position (H4) and a position closest to the lower limit imaging position (H10) is decided as a recommended imaging position.
