  • Publication number: 20210162508
    Abstract: A forming defect detection system for a three-dimensional additive manufacturing device which performs additive molding by emitting a laser beam to a powder bed is provided. This system specifies a candidate position of a forming defect on the basis of a change amount of a local temperature measured in an irradiated part of a powder bed irradiated by a laser beam. The system calculates a cooling speed at the candidate position on the basis of a temperature distribution and determines whether a forming defect exists on the basis of the cooling speed.

  • Publication number: 20210162505
    Abstract: A three-dimensional additive manufacturing device emits a beam to a powder bed formed by laying a powder on a base plate to harden the powder bed selectively. A sensor detects the shape or the temperature of a surface of the powder bed or a modeling surface. A defect in laying of the powder or a defect in emission of the beam is corrected on the basis of the detection result, before completion of forming of the next layer.

  • Patent number: 8336195
    Abstract: The invention is directed to an unfailing pickup operation of an electronic component from a component storage portion at a seam of storage tapes connected even using a connection tape and prevention of reduction in a pickup rate of an electronic component. A CPU sends a feeding command to a component feeding unit to perform a component feeding operation or the like. Then, when the CPU judges that a connection tape reaches a pickup position, the CPU drives an X axis drive motor and a Y axis drive motor to move a board recognition camera to the pickup position of the feeding unit, the camera takes an image of a storage portion of a storage tape, and a recognition processing device performs recognition processing. A correction value based on a result of this recognition processing is stored in a RAM, and a suction nozzle is moved taking this correction value into account and lowers to pick up an electronic component.

  • Patent number: 8099860
    Abstract: The invention prevents reduction of a pickup rate even when a storage tape in use and a new storage tape are connected to each other with a connection tape. A component recognition camera takes an image of an electronic component held by a suction nozzle, and a recognition processing device performs recognition processing. When a positional shifting amount calculated by CPU based on the recognition processing result is more than ?, a board recognition camera takes an image of a storage portion of a storage tape storing a next electronic component to be picked up. When a positional shifting amount of the storage portion calculated based on the recognition processing result is more than ?, the CPU enables seam passage processing. Based on the image taking of the storage portion by the board recognition camera and the recognition processing by the recognition processing device which are performed each time the storage tape is fed N times, the CPU controls correction of a pickup position.

  • Patent number: 7734121
    Abstract: A bidirectional optical module having a device 1 for emitting transmitting signal light, an optical fiber 8 which the transmitting signal light from the device enters, a light-receiving device 9 which light from the optical fiber enters, and a wavelength splitting filter 4. The transmitting signal light emitted from the device is sent forward through the optical fiber, and the receiving signal light is received through the optical fiber. The bidirectional optical module has an optical device (optical isolator) of a reflection polarizer 6 bonded to an end face of the optical fiber, a Faraday rotator 5 disposed integrally on the reflection polarizer and an absorption polarizer 3 disposed on an optical path extending between the device and the filter. The reflection polarizer has a wavelength dependency which functions as a polarizer for the transmitting signal light, but does not function as a polarizer for the receiving signal light.

  • Publication number: 20100072892
    Abstract: A halogen lamp including a glass bulb, a filament inserted inside the bulb, a pair of metal foils, and a pair of outer leads. Each metal foil has one end welded to the filament and the other end welded to the outer lead. The metal foils are contained in glass sleeves and they are collectively inserted inside the bulb. The bulb is softened by heating and shrinks because its inside pressure is reduced to seal the metal foils therein. Since the amount of glass of each sealed portion is larger than the other portions of the bulb by the amount of the sleeve, the shape of the sealed portion is stabilized.
