  • Publication number: 20050224974
    Abstract: A chip is bonded on a circuit board by aligning in position bumps with board electrodes with interposition of an anisotropic conductive layer between the chip and the circuit board. The anisotropic conductive layer is a mixture of an insulating resin, conductive particles and an inorganic filler. The chip is pressed against the board with a pressure force of not smaller than 20 gf per bump by virtue of a tool, while warp of the chip and the board is connected, the bumps are compressed, and the insulating resin is hardened.

  • Patent number: 6336007
    Abstract: An evaluation method and printer in which a maintenance man may easily identify a deteriorated component in addition to a component that is broken down or is remarkably hard to operate without the need for any additional complex detecting device. A printer has a control part which controls a mechanical part and judges quantitatively in which state among normal, deteriorated, and abnormal states each mechanical part component is located. This judgment will change in accordance with whether the printer is in a maintenance or a normal mode. Further, a deteriorated component can be determined by visually inspecting a copy after one or a combination of electric parameters have been set to printable upper and lower limits.

    Abstract: Within the hermetically sealed interior of a housing 9, a driving bevel gear 15 is fixedly secured to an input shaft 12 coupled via a rotation transmission cable 5 to an output shaft of a drive unit. A spindle 19 rotates jointly and coaxially with the driving bevel gear 15, which meshes with a driven bevel gear 17 coupled in such a manner as to allow a relative displacement in the axial direction. The spindle 19 has an externally threaded portion 19A screwed in an internally threaded portion 20A of a master metal 20. The spindle 19 has one end protruding from the housing 9 to the exterior, the one end being provided with a spindle chuck 21 for retaining a tap T.

  • Patent number: 6232998
    Abstract: A printing apparatus for printing on double-sides of a recording medium has a first print control unit for controlling an one-line exposure for the right or reverse side by a horizontal synchronous signal, and a second print control unit for controlling the one-line exposure for the reverse or right side by using this horizontal synchronous signal. A print start timing for the right side can be synchronized with a timing for the reverse side, and is capable of preventing a deviation in print position between the right side and the reverse side of the recording medium even by providing the print control units for the right side and the reverse side, individually.

  • Patent number: 6219149
    Abstract: A print processing apparatus realizes high speed processing of input data which includes various types of drawing objects such as images, graphics and characters. In the apparatus, input data generated by an input data generating unit is converted into intermediate data in an intermediate data generating element. An intermediate data order controlling element rearranges intermediate data pieces based on overlap therebetween and classifies them into groups, in each of which the data pieces can be processed in parallel. A group ID indicating a group for parallel processing, a hardware configuration ID and so on are assigned to the intermediate data piece. A rasterizing unit receives configuration data from a configuration data administering element, if necessary, in accordance with the hardware configuration ID assigned to the intermediate data piece, and rewrites a function of a reconfigurable rasterizing element under the control of the reconfiguration controlling element.

  • Patent number: 6165595
    Abstract: A parts-packaging substrate comprising a metal wiring plate having a mask coated on its surface with several openings. This structure eliminates the need for a thick base formed of an insulating body and a resist layer required in prior art substrates. By bending a terminal of the metal wiring plate to form a connecting terminal, a connector used to connect to another substrate can be eliminated, reducing the cost of manufacture.

  • Patent number: 6052143
    Abstract: A spindle unit control method controls a plurality of spindle units which rotate in synchronism with each other, and comprises with respect to each of the spindle units a first step of obtaining a phase error by comparing phases of a detection signal indicating a rotary reference position of the spindle unit and a first clock signal, a second step of generating a second clock signal having a phase which is adjusted by delaying or advancing the phase of the first clock signal by the phase error, and a third step of controlling the rotation of the spindle unit by a phase locked loop based on the detection signal and the second clock signal. The first clock signal is used in common with respect to each of the spindle units, and the second clock signal is independent for each of the spindle units.
