  • Patent number: 11031368
    Abstract: A bonding apparatus includes a movable light guide, a first capture, a second capture, a detector, an aligner, and a mover. When the movable light guide is positioned between a chip and a board, an image of the chip is made incident from a first incident port and emitted from a first emission port, and an image of a bonding position of the board is made incident from a second incident port and emitted from a second emission port. The first capture images the image of the chip emitted from the first emission port. The second capture images the bonding position emitted from the second emission port. The detector detects a relative positional deviation of the chip and the bonding position. The aligner relatively moves a bonding tool and a stage. The mover advances and retreats the movable light guide.

  • Patent number: 4829371
    Abstract: A color scanner for converting color data of a color original (e.g., a photographic film) into an electrical signal, includes a level comparator for discriminating the type of film (e.g., color negative vs. color positive, color vs. monochrome, type of color negative) in accordance with output signals, e.g., color component signals, from a sensor (i.e., based on a light transmittance of an unexposed portion of the film). The output from the level comparator is supplied to an accumulation time control block through a register, a selector, and the like. The accumulation time control block corrects the electrical signal based on the discrimination result from the level comparator irrespective of the type of film, so that an accumulation time of the sensor is changed by changing a bias voltage applied thereto.
