  • Patent number: 10642017
    Abstract: An imaging system includes: an image forming device that obtains image information of an object with the focal length to the object being changed by a variable focal length lens in an optical system, so as to form an all-focused image of the object; a sensor device that detects variations in the surface level of the object in a focus direction; and a position adjustment device that adjusts the position of the object in the focus direction in accordance with the surface level variations of the object detected by the sensor device. The position adjustment device adjusts the position of the object in the focus direction in such a manner that the surface level of the object becomes closer to the center of a variable focal length range of the variable focal length lens.

  • Patent number: 7921677
    Abstract: A vehicular upholstery fabric is made from a raw tricot fabric which is knitted by using a PPT-multifilament yarn whose single fiber fineness is about 0.5˜6.0 dtex and whose total fineness is about 30˜180 dtex for the ground yarn and the pile yarn. The raw tricot fabric has been transformed into a napped tricot pile fabric by raising the sinker loop of the pile yarn of the raw tricot fabric to form fluffs which are then sheared to form cut piles. A PPT-bulky multifilament yarn is used for the ground yarn. A PPT-non-bulky texturized multifilament yarn or a PPT-bulky texturized multifilament yarn is used for the pile yarn.
