Abstract: In a plasma device 30 that emits an electromagnetic wave to a combustion chamber 10 of an engine 20 so as to generate electromagnetic wave plasma thereby igniting mixture gas, fuel efficiency for lean burn mixture combustion of an engine 20 is improved. During a flame propagation after the mixture gas is ignited in the combustion chamber, the electromagnetic wave is emitted to the combustion chamber 10 so that electrons in a propagating flame resonate with the electromagnetic wave. The resonance between the electrons in the propagating flame and the electromagnetic wave increases flame propagation speed.

Abstract: A fiber transporting apparatus for a rotor type open end fine spinning machine is provided that may reduce an amount of effective fiber discharged from a burling opening portion without degrading yarn quality of the spun yarn. Fiber opened by a combing roller (11) is fed into a rotor through a fiber transporting channel (13) leading from a circumferential surface of the combing roller (11) to a predetermined position of the rotor (6) in accordance with a negative pressure degree within the rotor (6). After debris is removed from the opened fiber by a burling opening portion (12), the opened fiber is moved together with an air flow directed from a downstream side of the burling opening portion (12) in a rotational direction of the combing roller (11) toward an inlet (13a) of the fiber transporting channel (13).

Abstract: A rotor type open-end spinning machine of a structure in which fibers moving slidingly on an inner wall surface of an outer rotor (2) are prevented from falling at a location where a fiber bundle is being stripped off from a fiber collecting/bundling section (7) while being twisted concurrently. An inner rotor (5) is disposed within the outer rotor (2) and positively driven independently of the latter. A delivery passage (20) is formed in the inner rotor (5) for guiding a fiber bundle (F) bundled in a fiber collecting/bundling groove (7) to a yarn withdrawing passage (14). An annular negative-pressure chamber (6) is formed radially outward of the fiber collecting/bundling groove (7) of the outer rotor (2) with air discharge holes (9) being provided for communicating the negative-pressure chamber (6) to the exterior of the outer rotor (2).

Abstract: A rotor type open-end spinning unit has a collecting section collecting an opened and supplied fiber to make a fiber bundle. The fiber bundle is drawn through a yarn drawing passage to spin a yarn while twisting the fiber bundle. A rotatable outer rotor has an open end, a closed end and a peripheral wall. The peripheral wall has the collecting section on an inner surface thereof. The collecting section is located on a plane perpendicular to the rotational axis of the rotor. An inner rotor is located in the outer rotor and is driven independently. The inner rotor faces an end of the yarn drawing passage. A yarn path is provided with the inner rotor for guiding the fiber bundle from the collecting section to the yarn drawing passage. A first guide is provided with the inner rotor for contacting the fiber bundle guided to the yarn drawing passage through the yarn path from a frontward location with respect to the rotational direction of the inner rotor.

Abstract: Opened fibers are supplied into a rotor in high rotation, and a fiber bundle collected at a fiber-collecting section of the rotor is drawn as yarn from a yarn drawing passage provided on the open side of the rotor. A rotary assembly which is actively driven separately from the rotor is provided coaxially in the rotor. The rotary assembly has at least part thereof facing the vicinity of the fiber-collecting section and another part shaped to face a first end of the yarn drawing passage. The rotary assembly is provided with a yarn passage for guiding a fiber bundle to a position opposite the yarn drawing passage from the vicinity of the fiber-collecting section. A twist propagation preventing portion is provided in that end of the yarn passage that lies on the fiber-collecting section side. The rotation of the fiber bundle is suppressed by the twist propagation preventing portion, stopping the twisting.

Abstract: A fiber control apparatus in an open-end spinning frame is disclosed. According to the invention, in an open-end spinning unit having a fiber passage through which fibers opened by the combing roller are carried into the spinning chamber of the rotor, one or more nozzles are provided in the unit, each nozzle having an outlet opening located adjacent to the fiber outlet opening of the fiber passage so that one or more streams of jet air, emitted from the nozzle or nozzles, direct and guide the fibers introduced into the chamber toward the interior peripheral surface of the spinning chamber of the rotor, thus causing the fibers to reach said surface immediately without being slowed or bent by ambient air streams within the chamber. Consequently, formation of yarn having bent or randomly attached fibers is substantially prevented, whereby the strength and quality of the spun yarn is greatly improved.
