Title: Solid polymer electrolyte membrane and bipolar membrane fuel cell using it
Inventor: OKADA TATSUHIRO
IPC: H01M8/02
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain a fuel cell using a polymer electrolyte membrane by forming a joining part of a cation exchange membrane and an anion exchange membrane with a material constituting the cation exchange membrane and the anion exchange membrane. SOLUTION: A cation exchange membrane is arranged so as to come in contact with an anode, and as the cation exchange membrane, an fluorine base ion exchange membrane such as a perfluorocarbon sulfonic acid membrane or a perfluorocarboxylic acid membrane, a phosphoric acid impregnated polybenzimidazole membrane, polystyrene sulfonic acid membrane, or sulfonated styrene.vinyl benzene copolymer membrane is used. As an anion exchange membrane, a solid polymer electrolyte membrane whose catalyst carried surface is covered with polyorthophenylene diamine(PPD) by electrolytic polymerization is used. Joining is conducted by thermocompression bonding, a physical means such as mixing, solvent cast, blend, interface polymerization, or a chemical means such as co-polymerization.

Title: Ballpoint pen
Inventor: KOBAYASHI SEIICHI
IPC: B43K7/02
Filed: 1994-02-28
Abstract: PURPOSE:To prevent ink from flowing backwards during writing in upward posture and shock and flowing forwards when a pen is postured downwards and prevent a pen from becoming scratchy during writing in upward posture and writing in downward posture after shock. CONSTITUTION:Before writing, a ball valve 15 abuts against the rear end of projecting beads 16, resulting in opening a guide hole 20. The ink 21 flowing from an ink shoring tube 4 through the guide hole 20 into a valve chamber 13 is guided to the rear end of a tip ball 5a by passing through ink guiding grooves formed between the projecting beads. Since a tip ball 5a is brought into close contact with the inner edge of the tip holding part by being pressed with a bar shaft part 18, ink is prevented from flowing forwards. Further, by the minute retracting of the tip ball 5a due to the pressure of a pen, clearance develops, resulting in allowing ink to flow out. Since the viscosity of ink lowers through the rotation of the tip ball 5a, a large quantity of ink flow out, resulting in realizing high concentration writing. When a tip is postured upwards, the ball valve 15 comes into close contact with a ball bearing seat 14 so as to tightly seal the guide hole 20, resulting in preventing ink from flowing backwards.

Title: Reel control system
Inventor: SAIJIYOU HIROAKI
IPC: G11B15/58
Filed: 1981-04-09
Abstract: PURPOSE:To control the amount of tape in a buffer mechanism with a required minimum of reel motor torque and the buffer mechanism, by adding a circuit compensating the mechanical detection delay of the change in the amount of tape in the buffer mechanism. CONSTITUTION:A running state detecting circuit 11 detecting the running state change (start, stop) of a tape 1 and outputting a delay compensating signal, is  provided. When a capstan 2 starts running, a tape reel in a vacuum column 4  starts moving, but a reel motor M is not immediately driven due to delay of  detection. On the other hand, since a capstan running signal is outputted from a  control section at the same time as the start of run of the capstan 2, this state change is detected at a detection circuit 11. Next, a reel motor drive signal is  applied to a driving circuit 9 while a time corresponding to the delay time of a  tape loop position detecting circuit 5 to compensate the delay in the detection.  Thus, the amount of tape in the buffer mechanism can be controlled with a required minimum reel motor torque and the buffer mechanism.
