  • Patent number: 9044822
    Abstract: A double-sided bonding process using transient liquid phase (TLP) bonding structure. A first side of an electronic device is processed to partially complete bonding. A second side of the electronic device is processed to complete bonding. The first side completes bonding during the processing of the second side. This reduces the time needed for the bonding process of both sides. This process allows for various TLP bonding parameters while being compatible with conventional fabrication systems.

  • Publication number: 20130062016
    Abstract: A transfer apparatus transfers an object to be transferred onto a case. The transfer apparatus includes a transfer arm, an arm shaft, a plurality of electromagnets, and a control unit. The transfer arm has a pick unit on a front end thereof and extends and retracts in a horizontal direction. The object to be transferred is held on the pick unit. The arm shaft supports the transfer arm. The plurality of electromagnets apply an force in upward direction to the transfer arm by generating a magnetic field in the case. The control unit controls the plurality of electromagnets in such a manner that when the transfer arm extends and retracts in the horizontal direction, the force in upward direction applied to the transfer arm increases as a length from the arm shaft to the front end of the transfer arm increases.

  • Patent number: 7513967
    Abstract: A raw material including a mixture of a natural fiber and a thermoplastic fiber is supplied to a surface of a rotating rotary body. The natural and thermoplastic fibers are scattered toward a carrying surface of a conveyor belt by the rotational force of the rotary body. An air blower may direct pressurized air to the scattered raw material in order to further effect separation of the natural and thermoplastic fibers. Consequently, the natural fibers and the thermoplastic fibers are deposited such that the relative concentration of the natural fibers and the thermoplastic fibers gradually and seamlessly changes or varies across the thickness of depth of the resulting molded fiber material.

  • Patent number: 6975435
    Abstract: In the correction of the quantity of light of a light source used in an image reader which irradiates an original document with the light source, receives the reflected light by a CCD and reads the original document image, at the time of a document moving mode in which the document moves, correction of the quantity of irradiation light of the light source is performed by reading a first standard white board which extends over the whole area in the main scanning direction, prior to the initiation of readout of the moving document, and upon initiation of readout of the moving document, a second standard white board arranged outside the document passing area is read by using the same light source, with the read operation of the moving document, and correction of the quantity of irradiation light of the light source is performed based on the reflected light from the second white board.
