Title: Electrochemical device and its manufacturing method
Inventor: HIKUMA KOICHIRO
IPC: H01M8/10
Filed: 2000-07-28
Abstract: PROBLEM TO BE SOLVED: To provide an electrochemical device with lightened weight, simplified and miniaturized as a whole body by using fullerene derivative as a proton conductor to a fuel cell using gaseous hydrogen as a fuel and to provide its manufacturing method. SOLUTION: This electrochemical device is so constituted that the proton conductor part 1 composed of the fullerene derivative is disposed by sandwiched between a first electrode 2 which has a structure substantially not transmitting the hydrogen in its gaseous state, and a second electrode, in a frame comprising a housing outer frame 5a and a housing inner frame 5b, and the first electrode 2 is closely contacted with a partitioning plate 6. The gaseous hydrogen 12 introduced to the first electrode 2 side is thus fed from a feed port 7 to the first electrode 2 without being in contact with the proton transmission part, the hydrogen becomes a proton in the first electrode 2, moves to the second electrode 3, and is reacted with the air 13 introduced to the second electrode 3 side so as to generate power.  This constitution can eliminate any necessity of applying gas non-permeability to a proton transmission part 1, and dispense with a humidifier, so as to thin the proton transmission part and to lighten, simplify, and miniaturize the device.

Title: Transfer belt
Inventor: NODA SHUHEI
IPC: G03G15/16
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a transfer belt which is capable of achieving a higher speed and higher image quality, but does not require special process steps and devices, prevents adhesion and roll-up and does not require a force separation mechanism. SOLUTION: This transfer belt is formed by dry coating a transfer base material with a water base emulsion coating material containing a fluororesin. The dry coating consists in regulating the diameter of a spray nozzle to 0.2 to 0.4 mm and coating pressure to 0.1 to 0.3 MPa and spraying the water base emulsion coating material on the transfer base material, by which the solid content in the water base emulsion coating material is mainly adhered to the surface of the transfer base material and satin-like ruggedness is formed. Air is admitted between the transfer belt and paper sheets and conversely the transfer of the satin-like ruggedness on the surface to the paper sheets is averted by regulating the surface roughness (Rz) of the transfer base material within a range 10 to 30 μm.  The higher speed and the higher image quality may be achieved without requiring the special process steps, devices or mechanisms.
