Abstract: According to the present invention, main and subcombustion chambers into which fuel is fed directly in an atomized state and in each of which a swirl is formed, are formed in communication with each other in a top portion of a piston, in order to use not only gas oil but also other volatile fuels of low cetane number such as gasoline and alcohol. Further, in order to improve the combustion performance, fuel is supplied into the subcombustion chamber in a finely pulverized state for easier evaporation, and fuel is adhered as liquid films to the main and subcombustion chambers. By so doing, ignition is ensured in all load conditions and it becomes possible to effect evaporation and combustion on the wall surface of each combustion chamber. Consequently, it is possible to obtain a combustion performance which is low in combustion noise and vibration and also low in the formation of unburnt matter.

Abstract: The present invention provides a method and apparatus for collecting and liquefying off-gases, particularly carbon dioxide, generated by a wet oxidation of organic matter and for the on sight gasification of liquid oxygen for use as an oxidant in the wet oxidation reaction. Through a series of separation and pressurization operations, high pressure off-gases are introduced into a heat exchanger at substantially the same time as liquid oxygen. The liquid oxygen and compressed off-gases are in heat exchange relation in the heat exchanger but are isolated from one another. Heat is transferred from the compressed off-gases to the liquid oxygen whereby the off-gases are liquified and the liquid oxygen is gasified. The liquified off-gases may then be stored in appropriate storage units. The gaseous oxygen is used as the oxidant for the wet oxidation reaction.

Abstract: A method is provided for enhancing the transport of a selected ion having a predetermined charge-to-mass ratio through a biomolecular membrane located in a space subjected to a local magnetic field. The space defines at least one reference path passing through the membrane in opposite first and second directions. The method includes the steps of creating a magnetic field which, when combined with the local magnetic field, produces a magnetic field having a flux density with at least one component representable by a component vector having a direction extending in the first direction along the path. This component of the magnetic field has a magnitude that fluctuates at a predetermined rate to produce a nonzero average value. A predetermined relationship between the ratio of the selected rate to the nonzero average value and the charge-to-mass ratio of the predetermined ion is thereby created. The predetermined relationship, is a function of the cyclotron resonance frequency of the ion.

Abstract: A capacitive pressure sensor suitable for making highly sensitive, low pressure measurements is disclosed. The sensor may be mounted into a 0.5 mm OD catheter suitable for multipoint pressure measurements from within the coronary artery of the heart. The sensor employs a transducer which consists of a rectangular bulk silicon micro-diaphragm several hundred microns on a side by two microns thick, surrounded by a supporting bulk silicon rim about 12 microns thick. Both the diaphragm and the rim are defined by a double diffusion etch-stop technique. The transducer fabrication process features a batch wafer-to-glass electrostatic seal followed by a silicon etch, which eliminates handling of individual small diaphragm structures until die separation and final packaging. An addressable read-out interface circuit may be used with the sensor to provide a high-level output signal, and allows the sensor to be compatible for use on a multisite catheter having only two electrical leads.
