  • Patent number: 7038143
    Abstract: A wiring board includes a first conductor formation substrate having a first substrate and a first electrode; a second conductor formation substrate having a second substrate and a second electrode; and a dielectric sandwiched between the first conductor formation substrate and the second conductor formation substrate. The dielectric includes a dielectric film that is not melted during thermo-compression bonding, and an adherent insulator melted during thermo-compression bonding. The surface of the dielectric film is subjected to a treatment to improve wettability. Adherence of the adherent insulator in thermo-compression bonding to the dielectric film is facilitated. The distance between the first electrode and the second electrode is made uniform by interposing the dielectric film between the first and second electrodes. A wiring board ensured as to lifetime and improved in reliability, and a simple method of fabricating such a wiring board are achieved.

  • Publication number: 20030213615
    Abstract: A wiring board includes a first conductor formation substrate having a first substrate and a first electrode; a second conductor formation substrate having a second substrate and a second electrode; and a dielectric sandwiched between the first conductor formation substrate and the second conductor formation substrate. The dielectric includes a dielectric film that is not rendered molten during thermo-compression bonding, and an adherent insulator rendered molten during thermo-compression bonding. The surface of the dielectric film is subjected to a treatment to improve wettability. Adherence of the adherent insulator rendered molten in thermo-compression bonding to the dielectric film is facilitated. The distance between the first electrode and the second electrode can be set constant by interposing the dielectric film between the first and second electrodes. Accordingly, a wiring board ensured in lifetime and improved in reliability, and a fabrication method of such a wiring board can be obtained.

  • Patent number: 6451710
    Abstract: A method of manufacturing highly reliable and highly dense printed wiring board which is not warped even by the application of pressure and heat in manufacturing the multi-layer printed wiring board. The highly precise and highly dense multi-layer printed wiring board is realized by using an uncured resin sheet reinforced with fiber as an interlayer insulating layer, forming non-through holes in the uncured resin sheet using a laser beam, filling the non-through holes with a conductive paste, half-curing the conductive paste to form a wiring material, and sticking the wiring material onto the wiring substrate by application of pressure and heat, without causing a deviation in position even in applying pressure and heat.

  • Patent number: 4452866
    Abstract: A tin-containing aluminum alloy is usually pressure-welded to a backing steel plate and used as a bearing. This bearing, however, is defective in that aluminum crystal grains and tin precipitates are coarsened in the alloy structure and the high temperature hardness and fatigue-resistant strength of the bearing alloy are reduced.The present invention provides an aluminum alloy comprising 2.5 to 25% by weight of tin, 0.5 to 8% by weight of zinc and 1 to 7% by weight of at least one element selected from the group consisting of silicon, chromium, manganese, nickel, iron, zirconium, molybdenum, cobalt, tungsten, titanium, antimony, niobium, vanadium, cerium, barium and calcium, with the balance being substantially aluminum. In the aluminum alloy of the present invention 0.1 to less than 1% by weight of chromium may be incorporated of 1 to less than 1% by weight of chromium may the like. The alloy of the present invention is effectively used as a bearing for a crank shaft of an automobile or the like.

  • Patent number: 4287420
    Abstract: A stereoscopic X-ray device used for stereoscopic radiography generates X-rays from a pair of X-ray focal spots. The X-ray device is provided with an evacuated envelope, an X-ray target within the evacuated envelope, and a cathode structure having at least two pairs of filaments. The first pair of filaments form relatively large size X-ray focal spots on the target. The second pair of the filaments form relatively small size X-ray focal spots on the target and are situated between the first pair of filaments on the cathode structure. As a result of these two pairs of focal spots on the X-ray target, a relatively small X-ray device can be used to provide magnification of stereoscopic images of high stereo quality.

  • Patent number: 4274005
    Abstract: In an X-ray apparatus for a computed tomography scanner, a plurality of combined X-ray tube segments are arranged round the central axis of the apparatus on which a subject to be examined is disposed. The X-ray tube segments each include a large number of electron beam generating means to produce an electron beam, a strip-like target having a surface against which the electron beam strikes and extending along a circular arc round the central axis, and an envelope containing these components. Along the surfaces of the X-ray tube segments facing the central axis lie a large number of X-ray detector elements to detect doses of fan-shaped X-ray beams emitted from the target and transmitted through the to-be-examined subject. The electron beam generating means successively produce electron beams, and fan-shaped X-ray beams are applied one after another to the subject from around the same.
