    摘要： A dry powder, for example, a medicament for an inhaler, comprises elongated particles with an aspect ratio sufficient to cause the particles to be bound to a preferably metal or non-metallic sheet material substrate at the particle tips by electrostatic deposition and for aligning a plurality of particles with their major axes aligned normal to the substrate and oriented tip-to-tip. Particles deposited form a low density, high relative void deposition to minimize attractive forces between the particles. This minimizes agglomeration and bonding forces to the substrate facilitating the release of a powdered medicament in an inhaler. Medicament dosages in a substrate pocket are covered by a sealing layer. An embodiment of a drug dosage inhaler substrate and inhaler is disclosed.

    摘要： The invention is directed to an induction coil which includes a flat spirally wound portion and a tubular spirally wound portion extending from the outer edge of the flat portion. The axis of the tubular portion is substantially perpendicular to the flat portion. The coil is useful in a plasma production apparatus which includes a chamber having walls and adapted to be evacuated. A window extends into the chamber from one of the walls. The coil is in the window with the flat portion being at the bottom of the window.

    摘要： A triode plasma reactor having first, second and third electrodes for forming a plasma in a reaction chamber from a reactant gas includes a phase modulated potential generator for generating time varying potentials on the second and third electrodes which are phase modulated versions of one another. The phase modulated versions may also include a fixed phase shift between them. By time varying the phase angle relative to a set phase shift, a new dimension of time varying control for the reactor may be obtained. Phase modulation at frequencies from audio frequencies to radio frequencies may be provided. Phase modulation may be accomplished digitally or in the analogue domain.

    摘要： The present invention provides, in a preferred embodiment, a cylindrical stainless steel cathode with end pieces thereon to form a cathode chamber within. In addition, in a preferred embodiment, there is a stainless steel rod which passes axially through the cathode chamber and which is electrically insulated therefrom at the end pieces. The stainless steel cathode has first and second apertures formed therein with the first to be connected to a source of ionizable gas and the second to act as the opening through which there passes a stream of ions to an ion beam target. A magnetic flux source is coupled to the cathode chamber to pass magnetic flux therethrough and a voltage source is connected between the anode and the cathode to provide an electrostatic field therebetween whereby when ionizable gas is fed into the cathode chamber, it is ionized and a stream of ions emanates from the second aperture. In a preferred embodiment there is further provided an electrostatic ion focusing means to focus the ion stream emanating from the second aperture.
