  • Publication number: 20020057179
    Abstract: In an individual ignition type ignition coil for use in an internal combustion engine in which a center core 1, a secondary coil 3 wound on a secondary bobbin 2 and a secondary coil 5 wound on a primary bobbin 4 are installed concentrically from an inner side of a coil case 6 in order. Among these interior constituting members, insulation resins 17 and 8 are filled up. Each of the primary bobbin 4 and the secondary bobbin 2 is made of a synthetic resin and at least a skin layer on an inner surface of the primary bobbin 4 and a skin layer on an outer surface of the secondary bobbin 2 are removed, and to the surfaces of the bobbins, the insulation resin 8 is adhered closely. By heightening a close adhesion strength (a bonding strength) of a bobbin and an insulation resin in an individual ignition type ignition coil, an anti-heat shock is improved and an insulation performance of the coil is attained.

  • Patent number: 6339375
    Abstract: An image monitoring apparatus for detecting a confined passenger in an elevator just from an image, without using a dedicated sensor. The image monitoring apparatus includes an image acquirer for acquiring an image; a door area definer for defining a door defining area for the image; a door extracter for extracting a door image from the door defining area of the image; a door open/closed state sensor for determining whether the door is open or closed; a passenger area definer for defining a passenger defining area; a passenger extracter for extracting a passenger image from the passenger defining area of the image; a passenger presence determination for determining whether a passenger is present; a decision unit for determining whether a passenger is confined in the closed space by whether the door is open or closed and the passenger presence determination; and an alarm for issuing an alarm if a passenger has been confined in the closed space.

  • Patent number: 5938265
    Abstract: A vehicle seat structure comprises: a connecting member which connects an outer side reclining apparatus in a widthwise direction of a vehicle and an inner side reclining apparatus in the widthwise direction of the vehicle to be interlocked with one another; a reinforcing member which is tubular and is provided adjacent to the connecting member, one end portion of the reinforcing member being fixed to a structural member of the outer side reclining apparatus and another end portion of the reinforcing member being fixed to a structural member of the inner side reclining apparatus; and deformation direction control apparatus for deforming the reinforcing member in a direction other than a direction in which a seating space of a vehicle occupant becomes narrower, when a side collision load is larger than a buckling load of the reinforcing member.

  • Patent number: 5625717
    Abstract: An image processing device includes: a DOG filtering means for applying a DOG filter upon the grey level image of an object; and a tri-level thresholding means for thresholding the output of the DOG filtering means at two distinct threshold levels, thereby obtaining a tri-level image of the object. The 0-level regions of the tri-level image correspond to regions of the original image, such as the surface areas of the object, within which the variation of the grey level is small. The boundary between two 0-regions is marked by adjacent parallel strips of a (+)-region and a (-)-region, wherein the zero-crossing line between the (+)-region and the (-)-region clearly defines the contour line of the 0-regions. This method of tri-level quantization provides a basis for efficient template matching of the images of objects, recognition or identification of objects, the detection of movement vectors of objects, and the detection of the parallax of a continuously moving objects.

  • Patent number: 4942618
    Abstract: A method and apparatus for determining the shape of a wire or like article is provided in which a plurality of image pickup means are provided that view the wire through coaxial optical systems having their focal planes positioned differently from each other, the wire images imaged on the respective image pickup means are processed to determine the contrast and size of the images, and the results are used to determine the shape of the spatially disposed wire or the like.
