    Abstract: The present invention relates to a diffusion joining method of Cu or Cu alloy surface and a conductive paste used therefor, especially applied to a method for preparing a multilayer printed wiring board. The present invention is characterized by providing the contacting surfaces with a layer selected from the group comprising a noble metal thin layer, a metal oxide remover layer and a conductive paste layer mainly consisting of a Cu or Cu alloy particles and the metal oxide remover; and pressing the contacting metal surfaces at a temperature higher than 170 DEG C more or less whereat the Cu atom at interface of the Cu or Cu alloy surfaces to be joined becomes to be able to diffuse, to give a joined metal body.

    Abstract: The fine-line pattern forming method is to form a pattern by transferring the pattern formed on the blanket of which surface is covered with an elastic material mainly composed of silicone resin, on a substrate on which a tack layer is formed. As an example thereof, the forming method of cathode-ray tube anode comprises a step of filling the groove of an intaglio with a graphite ink, a step of transferring the graphite ink in the groove of the intaglio on a blanket of which surface is covered with an elastic material mainly composed of silicone resin, a step of forming a tack layer on a substrate, a step of transferring and printing the pattern transferred on the blanket onto the substrate, a step of filling the groove of the intaglio with a phosphor ink, a step of transferring the ink in the groove of the intaglio on the blanket of which surface is covered with an elastic material mainly composed of silicone resin, a step of forming a tack layer on the substrate, a step of transferring and printing the pattern transferred on the blanket on the substrate on which the graphite pattern has been formed, a step of transferring an aluminum thin film possessing multiple pores as a metal-backed layer so as to cover a black matrix and a phosphor layer, and a step of firing the substrate covered with the aluminum thin film. The graphite ink comprises graphite powder, vehicle containing depolymerization type organic binder, and organic acid metal salt. The phosphor ink comprises phosphor powder and vehicle containing polymerization type organic binder.

    Abstract: To obtain low insertion loss and low TTE level, a first central transducer, a second transducer and a third transducer are disposed on one surface of a piezoelectric substrate in such a manner that the second and the third transducers are in the direction of propagation (X-direction) of surface acoustic waves launched by the first transducer and the distance between center lines of the first and the second transducers and also the distance between the center lines of the first and the third transducers vary along the Y-direction perpendicular to the X-direction.
