  • Method of detecting the position of stacks of blanks for supply to a cigarette packing machine
    Patent number: 6603135
    Abstract: A method of detecting the positions occupied on a pallet by stacks of blanks arranged on the pallet in a number of superimposed layers and, in each layer, in a number of side by side rows, to enable automatic pickup of each stack and supply of the stack to a cigarette packing machine; the method including the step of moving a sensor along each row to determine a lateral contour of the row close to bases of the relative stacks.

  • Photo-detecting module having a fiber optic groove on rear surface of integrated circuit device
    Patent number: 6403948
    Abstract: On a module substrate on which a wiring pattern is formed, an integrated circuit device is mounted via solder bumps so that the front surface thereof faces the module substrate. An optical fiber is seated within a groove formed on the rear surface of the integrated circuit device. Additionally, a photo-detecting device is mounted on the module substrate for receiving light transmitted through the optical fiber. This allows the photo-detecting module to reduce the number of mounted parts and to be fabricated in less time.
