Abstract: An electronically controlled micro-dispensing apparatus (10) is described. The apparatus includes a container (12), an adaptor (18), a nozzle (28) and a control circuit (34 or 42). The container is filled with the chemical (104) and propellant (102). The adaptor, nozzle and control circuit are removable from the container and are reusable. The control circuits controls the length of pulse and the time duration between each pulse. By controlling these factors, the apparatus dispenses a precise amount of liquid over a set time period. The ejector allows for controlled dispensing and allows the liquid to be sprayed a greater distance. In the preferred embodiment, the apparatus are used to dispense a pheromone in an outdoor setting, such as an orchard (100), to control insects.

Abstract: A process for depositing an adherent polycrystalline diamond thin film on a glass substrate, by chemical vapor deposition (CVD) at 1 to 15 torr and low temperatures of the substrate of between about 350 to 600.degree. C. using hydrogen and methane and optionally carbon dioxide. The substrate has diamond particles deposited on it or is polished with diamond particles prior to CVD. The process produces films which are clear and adherent.

Abstract: A plasma (56, 333) generating apparatus (10, 320, 450) wherein a stage (250, 300, 300A, 350, 400, 425) is constructed to keep the plasma on the substrate (S). A pair of electrically, non-conductive tubes (252, 252A, 303, 305, 303A, 305A 403, 405) are mounted on a conductive base plate (253,306,406) having holes (255, 306B) for gas flow and one of the tubes supports a conductive support plate (251, 301, 351, 401) for a substrate (S). An electrically conductive disk (304, 404) between the tubes is provided. An outer conductive tube (307, 418) is preferably used with larger diameter chambers. The stage is designed to prevent the plasma from falling below conductive support plate which preferably mounts a graphite insert (302, 352, 402) which supports the substrate.
