Title: Operating method for molten carbonate fuel cell
Inventor: MARUYAMA SHINICHI
IPC: H01M8/04
Filed: 1986-04-21
Abstract: PURPOSE:To safely operate without clossleak in a break in load by setting gas pressure on fuel electrode side higher than that on oxidizing agent electrode side during load operation. CONSTITUTION:In a molten carbonate fuel cell, gas pressure on fuel electrode (anode) side is made higher than that on oxidizing agent electrode (cathode) side, and the differential pressure between fuel electrode side gas pressure and oxidizing agent electrode side gas pressure is made lower than bubble resistant pressure during load operation of the cell. Even if the fuel electrode side gas pressure is decreased and the oxidation agent electrode side gas pressure is increased when a load is cut off, a transient differential pressure is low compared with the differential pressure generated when a load is cut off in isobaric load operation in which fuel electrode side gas pressure is equal to oxidizing agent side gas pressure. Therefore, generation of crossleak in a break in load can be prevented.

Title: Freshness retentive resin composition for plant and freshness retentive molding for plant
Inventor: IIJIMA YOSHIHIKO
IPC: C08K5/09
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain a resin composition which can inhibit a plant from forming ethylene to keep it fresh for a long time by adding cinnamic acid and/or a cinnamic acid derivative to a thermoplastic resin and to provide a molding by molding the composition. SOLUTION: 0.05-10 wt.% freshness retentive component being cinnamic acid and/or a cinnamic acid derivative (e.g. caffeic acid or p-coumaric acid) are added to a thermoplastic resin selected among polyethylenes, polypropylenes and polystyrenes. The obtained composition is molded into e.g. a plastic film, sheet or container, and the obtained molding is used as a freshness retentive packaging material. When this molding is used for packaging perishables or flowers which spontaneously generate ethylene to age themselves, the cinnamic acid or the derivative gradually released from the packaging material inhibits their ethylene biosynthesis enzyme to inhibit them from generating ethylene. As a consequence, worsening of freshness can be prevented.

Title: Sheet feeder
Inventor: TAKAHASHI YASUHIRO
IPC: B65H3/06
Filed: 1986-04-22
Abstract: PURPOSE:To prevent dublicate feed of paper by providing a spring device for resiliently urging a sheet separating pad against a sheet separating roller and increasing the spring constant of the spring device, when the retracting amount of the sheet separating pad is above a predetermined value. CONSTITUTION:When more than two sheets of paper P is delivered between a sheet separating roller 3 and a sheet separating pad 5 from a feeder table 1, insertion of these sheets P between the sheet separating roller 3 and the sheet separating pad 5 causes the retracting amount of the pad 5 from the outer periphery of the roller 3 to become larger than a clearance t, so that a piece 15 of an auxiliary spring force imparting lever 12 is brought in abutment against a pad holder 6, causing counterclockwise rotation of the lever 12 against a spring 15. Therefore, the total spring force of the springs 10 and 15 is exerted on the pad 5, causing increase of the spring constant as well as increase of the pressing force against the roller 3. Thus, dublicate feed of paper P can be prevented.

Title: Magnetic recorder and reproducer
Inventor: MAEDA MASAYA
IPC: G11B15/18
Filed: 1981-06-16
Abstract: PURPOSE:To perform the switching of the driving system with small load, by providing releasably a sliding member containing a damping part to the feed and takeup reel tables of a magnetic tape and a member that prevent a contact between a reel driving means and a reel table. CONSTITUTION:A shaft 37 of an idler 38 is set in a triangular hole 45 of an idler control slide 45 provided at the center part between the reel tables 11 and 12. When the slide 45 is set at the lowest edge, the shaft 37 touches a slant surface 45-b of the hole 45. As a result, the idler 38 has no contact with the tables 11 and 12 although a reel driving rib 26 turns. When the idler 38 moves up and the control of the surface 45-b to the shaft 37 is released, the idler 38 presses one of the tables 11 and 12 according to the turning direction of the rib 26. Thus the fast forwarding and fast rewinding are carried out. The switching is carried out between the fast forwarding and rewinding by operating a changeover lever 51 to make the lever 54 push up the slide 45. Thus the switching is possible with small load.
