Filed: 2008-05-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing contacts capable of improving contactability between electrochemically active discs and interconnectors in flat high-temperature fuel cells; and a fuel cell having such contact.  <P>SOLUTION: The interconnectors have air-side and gas-side surface profiles with contact surfaces located on raised portions. In this method, a layer consisting of a contact mixture containing conductive particles and a medium with the particles embedded therein is respectively stuck to the electrodes of the electrochemically active discs. The outline surfaces of the electrodes are brought into contact with the layer so that, at a working temperature, the raised portions penetrate into the layer; connection parts are formed between the contact surfaces and the conductive particles; and thus discrete, homogeneously structured connection parts are formed between the contact surfaces and the electrodes. The medium is a hot melting constituent which is in a solid state at room temperature, and in particular at a temperature below 40°C, and in a liquid state at the working temperature. Finally the medium embedding the particles is thermally removed, and the discrete connection parts are solidified.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To surely exhibit effects of ink mist reduction etc. of a strip-shaped ink receiving member in a constitution which uses the strip-shaped or the like ink receiving member at a spare ejection receiving part of an inkjet recorder.  <P>SOLUTION: A strip-shaped ink receiving surface member 402 is formed in the shape that regions of a fixed interval in an extension direction of an ejection opening array alternately shift in left direction and right direction along a main scan direction centering a position where to be struck with the ink. For example, even when a spare ejection region shifts by decrease of an ink ejection speed or the like, a region to be struck with the spare ejection ink can be secured in the region shifted to one side of the ink receiving surface member. In other words, even if a striking position shifts, the ink ejected from a part of ejection openings or its satellite can be received in the region shifted to one side of the ink receiving surface member. A mist reduction by a constant amount is enabled with the effect maintained by the strip-shaped receiving surface member.  <P>COPYRIGHT: (C)2010,JPO&INPIT
