Latest Patents
One of Shigeta's latest inventions is a surface inspection apparatus and method. This apparatus includes a light source that applies a detection laser beam to a film sample. A light receiver, equipped with multiple photomultiplier tubes arranged across the width of the film sample, receives output light reflected by the film. A defect detector identifies defects on the film sample based on the output signals from the photomultiplier tubes. Additionally, a sensitivity corrector adjusts the sensitivity of these tubes to minimize output noise. This corrector ensures that the sensitivity difference between the tubes remains within a predetermined value. Furthermore, multiple light valves upstream from the light receivers are controlled by the sensitivity corrector to manage their transmittance.
Another significant patent is for a method of and apparatus for processing a rolled article to apply a packaging sheet. This apparatus features a rotary supporting mechanism that rotatably supports the ends of a photosensitive roll. It also includes an end drawing mechanism that draws the sheet end of the roll to a specified length, a pressing mechanism that supports the sheet end's surfaces, and an applying mechanism that applies a joint tape to the sheet end in a transverse direction.
