摘要:
In an internal combustion engine 20 that promotes combustion of fuel injected from an injector 50 to a combustion chamber 21 by way of electromagnetic wave plasma, a plurality of pieces of the electromagnetic wave plasma are generated respectively for a plurality of jet flows inlected from the injector 50. A plurality of antennae 36 are provided respectively for a plurality of injection holes of the injector 50. Each antenna 36 is disposed on an exposed surface 46a of a piston 46 exposed to the combustion chamber 21 at a location corresponding to each injection hole 55. While the injector 50 injects fuel, each antenna 36 emits the electromagnetic wave to the combustion chamber 21, thereby generating the electromagnetic wave, plasma.

There is provided an ignition or plasma generation apparatus that eliminates the need for resonance means in a combustion chamber and simplifies the electrode structure within the combustion chamber in an instance where energy from each of a spark discharge and microwaves is used to ignite an air-fuel mixture gas in an internal combustion engine. The ignition or plasma generation apparatus includes a mixing circuit for mixing a high-voltage pulse from a high-voltage pulse generator and microwave energy from a microwave generator; and an ignition plug into which an output from the mixing circuit is supplied, the plug used for introducing the output into a combustion chamber of an internal combustion engine. The output supplied from the mixing circuit to the ignition plug is supplied in a manner in which the microwave energy and the high-voltage pulse are superimposed on each other on a same transmission line.

Stable and highly efficient combustion/reaction is provided, even when fuel ratio of mixture is decreased and combustion/reaction of the lean mixture is performed in a heat engine such as a reciprocating engine, by controlling dielectric constant of mixture in a combustion/reaction chamber by introducing water and/or exhaust gas into the combustion/reaction chamber. A microwave radiation antenna for irradiation of the combustion/reaction chamber, and a discharge unit for igniting the mixture in the combustion/reaction chamber are provided. The dielectric constant of the mixture before the combustion/reaction of the mixture is controlled so that the resonance frequency of the mixture corresponds to the frequency of the microwave.

The invention provides a practical diesel engine that uses plasma formed by microwave emissions. In a compression-ignition internal combustion engine, fuel is sprayed by an injector in the combustion chamber in which compressed oxidizing gas is present, and the fuel is compressed and ignited. The engine has one antenna or a plurality of antennas in the combustion chamber, and when the oxidizing gas or moisture and charged particles are present in the combustion chamber, an electromagnetic wave is emitted using the antenna in a space in which the oxidizing gas and the charged particles are present, and plasma is generated in the space by the energy fed to the charged particles.

A chemical resistant glove is provided which comprises a chloroprene-based rubber as a first layer and a mixed rubber layer containing a nitrile-butadiene-based rubber and a chloroprene-based rubber as a second layer sequentially formed on a fabric glove, wherein a mixing ratio of the nitrile-butadiene-based rubber and the chloroprene-based rubber in the mixed rubber layer as the second layer is 60:40 to 10:90 in a solid weight ratio. The chemical resistant glove of the present invention is excellent in chemical resistance, tactile feeling and the abrasion resistance.

The present invention provides a database system capable of dealing with dynamic changes in an event that vary continuously with time. A database system outputs a retrieval output from data in response to a user's retrieval request on the basis of a retrieval logic. The retrieval logic is allowed to evolve on the basis of a logical model. This logical model establishes a general relationship which leads results from conditions relating to a group of events that are dealt by a data group. Moreover, a database system optimizes a data structure on the basis of the logical model. The logical model can be transferred in a separated manner from the specific data contents of the data group. Therefore, the logical model can be exported to another database system of the same kind, and also imported from another data base system of the same kind.
