  • Patent number: 9389123
    Abstract: A mask used in a dual pyroelectric sensor and configured to allow the pyroelectric sensor to accurately detect a movement of a moving object in each of the disposition direction of two pyroelectric elements and a direction perpendicular to the disposition direction. The mask is applied to the sensing surface of the dual pyroelectric sensor to increase the sensitivity with which the pyroelectric sensor detects a moving object. The mask includes a sheet configured to block infrared rays and an aperture pattern including through holes formed in the sheet. The aperture pattern is formed in such a manner that the percentages of the respective infrared-irradiated ranges of the two pyroelectric elements of the pyroelectric sensor vary with a movement of a moving object in each of x- and y-directions.

  • Patent number: 8282107
    Abstract: An oil seal for reciprocation motion including a seal main body, a resin backup ring, and a holding member. The seal main body includes a seal lip that can be in sliding contact with a reciprocating shaft. The backup ring is disposed such as to support the seal lip from the atmosphere side to ensure durability of the seal lip. In the backup ring, at least a single annular groove is provided on the inner peripheral surface opposing the reciprocating shaft. The annular groove can hold a lubricating material. The holding member holds the backup ring between the holding member and the seal main body in a sandwiched-state. The inner peripheral surface of the backup ring forms a taper that increases in diameter from a sealed side towards an atmosphere side in the axial direction.
