  • Patent number: 11491917
    Abstract: A tilting mechanism of a view device for a vehicle has a configuration in which a rotating section is rotatably supported on a shaft of a fixed portion. A helical compression spring is fitted onto the shaft. A plate is attached to the free-end side of the shaft via a washer. An outer circumferential surface of the shaft and a center hole of the washer include respective different diameter portions. A gap g in a radial direction is formed between the outer circumferential surface of the shaft and an inner circumferential surface of the center hole of the washer. The tilting mechanism includes a deviation mechanism. The deviation mechanism makes the gap g become narrow or zero at the different diameter portions at at least one place, the different diameter portions facing each other, by making the washer move relative to the shaft in the radial direction.

  • Patent number: 9332618
    Abstract: An LED lamp includes LED chips, a translucent cover housing the LED chips, a motion sensor unit, a condensing lens, and a power unit. The motion sensor unit includes a light receiving element for light of a predetermined wavelength. The lens condenses light of the predetermined wavelength onto the light receiving element. The power unit controls the state of operation of the LED chips based on an output from the motion sensor unit. The motion sensor unit includes a light shielding member disposed to overlap the light receiving element in an optical axis direction of the condensing lens and also to surround the light receiving element as viewed in the optical axis direction. The light shielding member is made of a material having a lower light transmissivity than that of the condensing lens for a range of wavelengths including the predetermined wavelength.

  • Patent number: 8091427
    Abstract: Disclosed herein are an apparatus and a technique for quickly detecting a defective portion including wastage, which has occurred in piping having a straight piping portion or a bending zone, in the nondestructive inspection using a guided wave. A guided wave sensor 3 included in a guided wave inspection device 4 is mounted to the outer surface of piping 1. A guided wave is propagated to an inspection area of the piping 1. If a defective portion exists, the guided wave sensor 3 receives the guided wave that has been reflected from the defective portion. As a result, the guided wave inspection device 4 can acquire receive information including receive information derived from the defect.
