摘要： Method for electrostatically depositing select doses of medicament powder at select locations on a substrate. Specifically, the apparatus contains a charged particle emitter for generating charged particles that charge a predefined region of a substrate and a charge accumulation control circuit for computing the amount of charge accumulated upon the substrate and deactivating the emitter when a selected quantity of charge has accumulated. Additionally, a triboelectric charging apparatus charges the medicament powder and forms a charged medicament cloud proximate the charged region of the substrate. The medicament particles within the medicament cloud electrostatically adhere to the charged region. The quantity of charge accumulated on the substrate at the predefined region and the charge-to-mass ratio of the medicament powder in the cloud control the amount (dose) of medicament deposited and retained by the substrate. Consequently, this apparatus accurately controls both medicament dosage and deposition location. Furthermore, since the substrate can be of any dielectric material that retains an electrostatic charge, the apparatus can be used to deposit medicament on substrates that are presently used in oral medicament consumption, e.g., substrates that are used to fabricate suppositories, inhalants, tablets, capsules and the like.
摘要翻译：将选择剂量的药物粉末静电沉积在基底上的选定位置的方法。具体地，该装置包含用于产生对基板的预定区域充电的带电粒子的带电粒子发射器和用于计算在基板上累积的电荷量并且在已选择的电荷积累时停用发射极的电荷累积控制电路。此外，摩擦带电装置对药物粉末进行充电，并在基底的带电区域附近形成带电药物云。药物云内的药物颗粒静电附着到带电区域。在预定区域上积累在基底上的电荷量和云中的药物粉末的电荷与质量比控制由基底沉积和保留的药物的量（剂量）。因此，该装置精确地控制药物剂量和沉积位置。此外，由于衬底可以是保持静电电荷的任何电介质材料，所以该装置可用于在目前用于口服药物消耗的基底上沉积药物，例如用于制造栓剂，吸入剂，片剂，胶囊等。

摘要： A tribo-inhaler having a container portion for electrostatically retaining a predefined dose of medicament powder, where the medicament is tribo-electrically charged; and apparatus, attached to the container portion, for extracting said medicament powder from the container portion. The container portion contains a plurality of polymeric beads that have diameters of approximately 50 to 200 microns. Each of the polymeric beads has a specific quantity of dry powder medicament electrostatically adhered to its surface. To remove the medicament from the cavity, a patient merely inhales air through the container portion. The air flow forcefully moves the beads within the container portion causing the medicament to dislodge from the beads and be carried by the air flow into the lungs of the patient.

摘要： In accordance with the present invention, a method of electrophotographically manufacturing a luminescent screen assembly for a color CRT 10 on an interior surface of a faceplate panel 12 is described. A volatilizable organic conductive (OC) layer 32 is provided on the interior surface of the panel and a volatilizable organic photoconductive (OPC) layer 34 overlies the OC layer 32. The method includes the steps of: establishing a substantially uniform electrostatic charge on the OPC layer; exposing selected areas of the OPC layer to visible light to affect the charge thereon; developing the selected areas of the OPC layer with a triboelectrically charged, dry-powdered, first color-emitting phosphor; sequentially repeating the charging, exposing and developing sequence for triboelectrically charged, dry-powdered, second and third color-emitting phosphors to form a luminescent screen comprising picture elements of triads of color-emitting phosphors; fixing the phosphors to the underlying OPC layer with a suitable fixative; filming the phosphors; and aluminizing the filmed phosphors. The present method is an improvement over prior methods because the fixing step utilizes an electrostatic spray to uniformly contact the phosphors and the underlying OPC layer with the fixative, without moving the phosphors.
