摘要： A laminated piezoelectric transducer, comprising a laminate of a plurality of piezoelectric plates with paste electrodes inserted therebetween and bonding the plates together. Rows of metal extrusions are made by electroless plating onto the paste electrodes on the peripheral outer surface of the laminate. Each row of the metal extrusions is formed onto and electrically connected to alternate paste electrodes, so that by electrically connecting each row of the metal extrusions, the laminate of the piezoelectric plates is electrically connected in parallel. This laminated piezoelectric transducer allows the formation of the paste electrodes on the entire or at least substantially the entire main surfaces of the piezoelectric plates, and eliminates the need for the usual metal plate electrodes inserted between the piezoelectric plates.

摘要： When a roll paper unit 200 is incorporated into an image formation apparatus, a second outlet guide member 92 is turned around a pivot 92a in the direction of an arrow G, i.e., moved from a position of solid lines to a position of two-dot chain lines, a rear end portion 92b of this second outlet guide member 92 pressing down a front end portion 80c of a guide member 80 to cause the guide member 80 to be turned around a central shaft 80d in the direction of an arrow H, i.e., moved from a position of solid lines to a position of two-dot chain line. Consequently, a path extending in the direction of an arrow C is closed, while a path extending in the direction of an arrow F is opened, the roll paper 72 being transferred in the paper feed direction. When the roll paper unit 200 is drawn out, the second outlet guide member 92 and the guide member 80 are turned in the directions opposite to those mentioned above. Consequently, the path extending in the direction of the arrow F is closed, while the path extending in the direction of the arrow C is opened, the roll paper 72 being transferred in the paper discharge direction.

摘要： A surface treatment of a glass fabric used for a fiber reinforced composite such as multilayer circuit boards comprises the steps of exposing the glass fabric to an atmospheric pressure plasma of a mixture gas to obtain a plasma-treated surface of the glass fabric, and coating an organosilane compound on the plasma-treated surface. The mixture gas contains as a reaction gas at least one of an oxidative gas and a fluorine-containing gas, and a rare gas as a carrier of the reaction gas. The mixture gas is pre-heated prior to the plasma excitation thereof. When the glass fabric includes an organic compound as a sizing agent, the organic compound can be efficiently removed from the glass fabric by the exposing step. For example, the organosilane compound can be coated on the plasma-treated surface by exposing the plasma-treated surface to a second atmospheric pressure plasma of a second mixture gas containing an organosilane monomer. The surface treatment of the present invention is useful to efficiently produce a multilayer circuit board having excellent adhesion between the glass fabric and a resin, and resistance to CAF (Conductive Anodic Filaments).
