The main body has a surface and a plurality of grooves and the grooves are positioned on the surface. The cushion is positioned on the surface of the main body and covers the grooves. The cushion positioned over the partial grooves is elastically pressed onto the paper-separating roller. The grooves are linear and the direction of extending the linear grooves is substantially parallel with the axis of the paper-separating roller, the linear grooves neighboring one another or each other. Besides, the cushion is made of flexible material and the main body is made of rigid material.

  • Patent number: 6597522
    Abstract: An optical system for imaging the surface of the bottom of a well of a microtiter plate made of a transparent material. This surface has an analysis preparation. The optical system comprises an enlarging lens and an incident-light illumination formed by a ring-shape, diffuse light source. The incident light illumination is arranged concentrically with the optical axis. The microtiter plate is illuminated from the backside by an approximately dot-shaped light source, which is arranged behind the diffuser disk and centered in relation to the optical axis. Reflections and material flaws in the area located outside of the measuring area to be evaluated are thus made invisible.

  • Patent number: 6580501
    Abstract: An apparatus for the visual inspection in particular of concealed soldered joints is provided, in particular between an electric or electronic component disposed on the surface of a printed circuit board and the printed circuit board. The apparatus includes with an ocular unit, a lens head, an image transmission unit for transmitting the image received by the lens head to the ocular unit and an illuminating device for illuminating the soldered joints to be tested. The lens head includes a device for image deviation which extends up to the axially outer end of the lens head, and in which the illuminating device is disposed in the lens head in such a way that the exit angle of the light of the illuminating device out of the lens head is substantially equal to the deviation angle of the image deviation. The exit point of the light is disposed next to the device for image deviation in the area of the axially outer end of the lens head.

  • Patent number: 6522466
    Abstract: An apparatus for an object in an ultramicropore space has a lens system so that an incidence point P with the diameter in a range from 0.3 to 0.7 mm comes to a position in a range of 12 to 17 mm away from the front side of an object lens 30. At the same time a reflection mirror 15 is positioned with a reflection mirror mounting member 8 formed with the V-shaped form in front of the object lens 30 and a reflection mirror holding frame 8 at the position of the incidence point. This arrangement is useful fir example to observe a soldered section 52 of an IC chip 50 by inserting this reflection mirror 15 into the ultramicropore space.

  • Publication number: 20020145813
    Abstract: A hand-held, portable apparatus has been disclosed to facilitate the viewing of an object by the human eye. The apparatus provides an electronic camera unit disposed on a holder mechanism and in electrical communication with an image processor module to capture the image of an object and format the image for display on a display device also disposed on the holder mechanism. At least one user-interfaced control mechanism is also disposed on the holder mechanism and in electrical communication with the image processor module for controlling the operations of the module to regulate display of the image by the display device. In this way the viewing of an object by the human eye is facilitated by the use of camera and the image enhancing features of the image processor module.

  • Patent number: 6430310
    Abstract: An optical member inspection apparatus includes an inspection optical system having a light source, and a diffusing means for diffusing the light emitted from the light source. The diffusing means has a central portion and a peripheral portion. The diffusion transmittance of the peripheral portion is higher than the diffusion transmittance of the central portion. The inspection optical system is also provided with an image pick-up means to pick-up an image of the optical member to be inspected, and is positioned so as to receive that light emitted from the light source and transmitted through the diffusing means and the optical member. A judging means is also provided, for judging whether or not the optical member has a defect, in accordance with image signals output from the image pick-up means.

  • Patent number: 6373633
    Abstract: A multi-aperture irradiation profile shaping system is presented that uses at least one arrangement of at least three apertures associated with a plurality of optical elements, wherein at least one optical element has positive optical power and another one element has negative optical power. The system may be implemented with the apertures in one, two, or three dimensions. The system yields a predetermined arbitrary irradiation profile on a target. The shape of the apertures may be any one of square, rectangular, and hexagonal. The shape of the apertures may also be asymmetric so that a rotation of the aperture shape by 180 degrees around an axis perpendicular to the surface of the aperture yields an inverted aperture shape. The system may be implemented with apertures having symmetric and asymmetric shapes that allow nearly 100% fill factor.
