Abstract: A belt-like work (11) provided with a photosensitive layer is conveyed in a work conveying direction F at a work conveying speed V. An illuminating section (30) illuminates a photomask (29) in an exposure period T synchronized with the work conveying speed V. The photomask (29) is disposed at a proximity gap from the belt-like work (11). Mask patterns (33) on the photomask (29) are exposed on the belt-like work (11) to form periodic patterns thereon.

Abstract: A laser apparatus includes: a plurality of laser diodes respectively having light-emission points and being fixed to a block so that the light-emission points are aligned along a direction; and a collimator-lens array integrally formed to contain a plurality of collimator lenses which are arranged along a direction and respectively collimate laser beams emitted from the plurality of laser diodes.

Abstract: A bonding apparatus has a probe for causing an LED chip to emit light before the LED chip is bonded on a board, an imaging system for recognizing the center of a light-emitting area of the LED chip and recognizing coordinates of a contour reference point of the LED chip with respect to the recognized center of the light-emitting area, and a light-emitting-element holding mechanism for positioning the LED chip in a bonding position on the board based on the recognized coordinates of the contour reference point. The center of the light-emitting area of the LED chip can be positioned highly accurately in a desired position on the board without being adversely affected by variations in the contour dimensions of the LED chip.

Abstract: A method of and apparatus for checking a wrapping state of a wrapped roll having end face covers by detecting the force required to press-fit a bushing into a cylindrical core tube and comparing the detected force with a threshold value which is based on the correlation between the force required to press-fit the bushing into the cylindrical core tube and the state of tucking of the end face covers.

Abstract: A wrapping state of a wrapped roll of a continuous sheet material which is rolled and wrapped with a sheet-like wrapping material is checked by taking an image of the wrapped roll placed in a predetermined position, and processing information on the image of the wrapped roll with respect to the density of the image, thereby detecting data on wrapping state of the wrapped roll, and determining whether the wrapping state of the wrapped roll is satisfactory on the basis of the detected data.

Abstract: A package of rolled photosensitive mateiral comprising a core, a photosensitive strip material wound around the core, a light-shielding leader connected to the end of the photosensitive strip material to shield the peripheral surface of the photosensitive strip material from light and side light-shielding covers connected to both sides of the light-shielding leader so that the boundary between the side light-shielding covers and the light-shielding leader corresponds to the boundary between the peripheral surface and the side surface of the photosensitive strip material. The core is formed by laminating at least 2 sheets of a base paper being moistureproof.

Abstract: A packaging apparatus for packaging rolled articles. The apparatus forms a pair of packaging materials for wrapping side portions of the rolled article. Edges of the pair of packaging materials are adhered to additional packaging material which wraps a circumferential portion of the rolled article. A splicer splices a trailing end of the second packaging material to a leading end of the rolled article and a winder winds the leading end of the rolled article and the second packaging material around the periphery of the rolled article. A gusseting device gussets the pair of packaging materials along the sides of the rolled article.

Abstract: In a method and apparatus for packaging a rolled web, a feed roller is located near each of opposed end faces of the rolled web to be packaged. The axis of rotation of a feed roller is inclined with respect to the radial direction of the roll, which radial direction intersects perpendicularly to the direction along which a wrapping material having side edge parts folded in L-shapes is fed, such that the outer periphery of the axis of rotation, which outer periphery is taken in the radial direction of the roll, is more forward with respect to the direction, along which the wrapping material is fed, than the inner periphery of the axis of rotation. A folding member is located on the side more forward than the feed roller with respect to the direction, along which the wrapping material is fed. The folding member is supported such that the space between the folding member and the opposed end faces of the roll varies periodically.

Abstract: An apparatus for filling an article into a bag having an open end and a closed bottom includes an article insertion station which inserts an article into the bag through the open end thereof, an open end portion forming station which forms the open end portion of the bag into a predetermined shape, an open end portion folding station which folds the formed open end portion of the bag, and a conveyor which conveys the bag from a bag feeding station to the open end portion folding station through the article insertion station and the open end portion forming station in sequence. The conveyor conveys the bag with the open end of the bag directed transversely to the bag conveying direction of the conveyor and said article insertion station inserts the article in the direction transverse to the bag conveying direction of the conveyor.
