Title: Variable type venturi carburetor
Inventor: KATOU TAKASHI
IPC: F02M7/17
Filed: 1983-02-25
Abstract: PURPOSE:To render the idling operation of an engine stable, by preventing fuel attached to a needle from flowing along the needle and dropping into intake air by providing an injection nozzle for ejecting bleed air toward the needle at the portion of a fuel passage located on the upstream side of a nozzle. CONSTITUTION:Fuel supplied to an engine is metered by a jet 15 and a needle 14. However, fuel is attacted to the outer surface of the needle 14 and flows toward a suction piston 3 along the needle 14, which causes degradation in the stability of idling operation of the engine. According to the present invention, an air injection nozzle 24 is provided on the upstream side of the outlet of a nozzle 20 so as to eject atmospheric air introduced from an air inlet port 25 toward the needle 14 and to thereby blow off fuel attached to the outer surface of the needle 14. Thus, since fuel is prevented from flowing toward the suction piston 3 along the needle 14, fuel is supplied continuously from the nozzle 20. Therefore, unstable operation of an engine is not caused even at the time of its idling operation when the quantity of intake air is small.

IPC: H01G9/02
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To use a separator, excellent in heat resistance, electrolyte absorbing capability and retaining capability, and high in ionic conductivity, to reduce internal resistance by forming the separator, positioned between counter electrodes, as a sheet wherein fluorine-containing imide polymer is supported to a porous polymer sheet. SOLUTION: A capacitor is formed by forming a separator, positioned between counter electrodes, as a sheet wherein fluorine-containing imide polymer is supported to a porous polymer sheet. It is preferable that the fluorine- containing imide polymer should have a polymerization unit containing a structure expressed as Formula I or II (wherein, M is H, NR<1> R<2> R<3> R<4> or PR<1> R<2> R<3> R<4> ; R<1> -R<4> are alkyl groups and/or allyl groups with a number of carbons of 1-4). The nitrogen part of the polymers having this structure is high in acidity and prone to dissociate ions. It is presumed that the nitrogen part of the polymer supported by the separator dissociates protons and the quarternary oninum ion and thus the ionic conductivity is improved and the internal resistance of the capacitor is reduced.
