A method for more selectively removing macromolecules from a plasma solution, whereby plasma containing the macromolecules to be removed is provided and heated to a temperature near or above normal body temperature but below the boiling point of the plasma solution. The heated plasma solution is filtered while at a temperature near or above normal body temperature but below its boiling point with a membrane filter to remove selectively macromolecules from the plasma solution. An apparatus for ac...

A plasma processor comprising a plasma generation portion in which a plasma is generated by electron cyclotron resonance, a source of a right hand polarized microwave and supplying it to the plasma generation portion, and a plasma reaction portion which accommodates a substrate to be processed with the plasma generated in the plasma generation portion. Owing to the production and supply of the right hand polarized microwaves, almost all of the microwaves injected into the plasma generation porti...

A filter having a filter housing with an interior within which, between two closure members, filter membranes in the form of hollow fibers are disposed. Between the hollow fibers a free flow space remains to which are connected two connected pieces disposed inclined on the housing. Through the connecting pieces, blood is supplied to enable filtration from the outside to the inside of the fibers. The connecting pieces are angled so as to provide the lowest possible flow resistance.

A processing apparatus and method utilizing a single process chamber to deposit a layer of doped or undoped silicon dioxide utilizing a silicon source and a dopant gas and a remote plasma from an oxygen source and a source of additional ultraviolet light.

A plasma monitoring method and a plasma monitor in a dry process which utilizes a plasma. Among a large number of chemical species which constitute the plasma, one or two specified chemical species suited to grasp the situation of the dry process has/have its/their plasma light/lights detected so as to obtain the three-dimensional distribution of the densities of the single specified chemical species or the ratios of the two specified chemical species in the plasma.

In a plasma generator for high-frequency supply of an induction coil containing a plasma of an aerosol with a substance to be analyzed, quarter-wave conductors of a quarter-wave resonant system are incorporated in the apparatus after having been divided and folded, which provides a significant saving in space. Added to the conductors are electric auxiliary circuitry for balancing the resonant system and for matching the frequency to a filled induction coil. The conduction coil is capable of up a...

The invention relates to a plasma reactor for flexible strand material (12) , comprising passages (20,22) for the strand material (12) to enter into and exit from the reactor chamber (16), electrodes (54,56,58,60) arranged in the reactor chamber (16) for generating a plasma, and at least one guiding element arranged in the reactor chamber (16) and being adapted to guide the strand material (12) along a processing path. In order to provide a compact plasma reactor (10) for flexible strand materia...

A plasma reactor for generating and maintaining plasma. The plasma reactor has a resonant cavity whose cross-section tapers in summit regions in which the wall of the resonant cavity is closed to such an extent that an excited field mode in the region of the cross-sectional tapered portions displays main peaks whose maximum field intensity is increased relative to the field intensity of adjacent secondary peaks. A reaction unit is provided in the region of a main peak with a substrate which is t...

A heating device which produces a plasma flame of elongated cross-section comprises a plasma torch and means for generating a magnetic field. The nozzle of the torch has an elongated exit aperture, across which the magnetic field is directed, and the torch incorporates at least one internal electrode arranged so that when an arc is struck between it and the nozzle the arc root at the nozzle will move along the aperture under the influence of the magnetic field.
