  • Patent number: 6334569
    Abstract: A reflow soldering apparatus for soldering a first component mounted on a substrate with a first solder having a first melting point and soldering a second component mounted on the substrate with a second solder having a second melting point higher than the first melting point. The reflow soldering apparatus includes a heat source for substantially uniformly heating the substrate, a capsule for enclosing the second component, and a vacuum pump for decreasing the pressure in the capsule. The melting point of the second solder can be lowered by operating the vacuum pump to decrease the pressure in the capsule by a given amount, so that the first component and the second component can be reflow-soldered at substantially the same temperature.

    Abstract: A magneto-optical recording medium includes a transparent substrate, an underlying layer, a reproducing layer, a mask layer, a recording layer, and a protection layer. Reproducing layer is an in-plane magnetization film at room temperature and is transformed into a perpendicular magnetization film at about 150° C. Mask layer is an in-plane magnetization film at room temperature and reaches the Curie temperature around 140° C. which is lower than the reproducing temperature. Only the region whose temperature has reached the Curie temperature is demagnetized, and the other region retains the in-plane magnetization. The width of region whose temperature reaches the Curie temperature is substantially equal to the shortest domain length of recording layer. The magnetic domain of recording layer is transferred to reproducing layer 3 through the demagnetized region of mask layer.

  • Patent number: 6334925
    Abstract: The present invention relates to a method for bonding together two disc substrates, at least one disc substrate having a UV transmissive-visible light reflective information recording layer provided on a UV transmission base. In this method, the disc substrates are bonded together, so that the information recording layer of one disc substrate faces the other disc substrate, by employing UV irradiation to cure a UV curable composition used as a bonding agent. In the case of the present invention, to cure the bonding agent, UV is irradiated in a single or repeating flash so as not to impair the information recording layer. As a result, the bonding agent can be cured in a shorter period of time with less energy consumed as compared to the conventional method of using conditions irradiation of UV light to cure a UV curable composition used as a bonding agent. Accordingly, the present method enables a product disc to be obtained in a shorter time, with less energy used, so that productivity (i.e.

  • 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.
