摘要:
A housing as part of a clothes dryer's gaseous fluid exhaust system containing components for maintaining an open restriction-free airflow channel for maintaining the dryer's efficiency and sized to fit within a typical wall cavity of a building. A means for filtering and removing excess clothes lint, preventing entry of lint particulate into the upper exhaust vent pipe that may block exhaust airflow or blend with down falling condensate, which is generated from a clothes dryer's warm moist exhaust airflow. A diverter to direct the exhaust airflow to a primary exterior location or to a secondary interior location. A means to separate falling condensate from exhaust airflow and dispose the condensate into an exclusive disposal system. The elements of this invention combine to secure the efficiency, longer life and safety of a clothes dryer and its exhaust system by removing lint particulate, separating exhaust airflow from falling condensate produced by a clothes dryer into the clothes dryer exhaust system.

A radon exhaust system comprising an exhaust side with a vent housing, a diagnostic bypass filter apparatus providing observation windows, a removable observation window, internal ice and object filter, internal ribbon flow indicators, internal water gutter with drain spout, an exhaust fan and a suction side coupled together to form a conduit through which gaseous fluid may be conveyed. The diagnostic bypass filter apparatus provides an enlarged elliptical air passage bulge and angular bend configuration having three observation windows, a fourth removable observation window, an internal ice and object filter, ribbon flow indicators, and an internal water gutter with drain spout for providing protection of the exhaust fan from falling ice, water and objects and visual inspection for flow in the exhaust system and access to the filter for cleaning.

A solar thermal collection cabinet is disclosed that includes a thermal mass comprising concrete mix and metallic pieces. The cabinet includes a corrugated metallic surface with a black finish that faces solar radiation. A plurality of metallic bolts attaches the black corrugated surface to the thermal mass, to enable good heat conduction to the thermal mass. Channels through the thermal mass enable heat transfer fluid to circulate through the thermal mass, the heat transfer fluid exchange heat for direct utilization, or to transfer heat to a thermal storage reservoir through suitable heat exchanger means. Alternatively, the thermal storage reservoir continuously receives and returns heat exchange fluid whereby over extended periods of time the system approaches a thermal steady state.

Using a two Reservoir System, a portion of the water moves from Reservoir to Reservoir. In its path, it collects air, which is expanded by Solar Energy, which helps to move weights, by an expanding and contracting float method to create substantial Hydro Power, after which it returns back to the path of which it started, without causing any pollution and without using any outside fuel whatsoever.

WARDLY OF THE SPRAY WHEREBY THE HEAD IS MAINTAINED IN A COAXIAL POSITION RELATIVE TO THE PIPE AS IT IS DRAWN THROUGH THE LATTER. DISCLOSED IS A MOTOR DRIVEN DRUM FOR DRAWING A SUPPLY HOSE AND AN APPLICATOR HEAD THROUGH A PIPE. THE HOSE COMMUNICATES THROUGH THE DRUM WITH A RESERVOIR CONTAINING COATING MATERIAL AND SUPPLIES THE LATTER TO THE APPLICATOR HEAD FOR COATING THE WALL OF A PIPE. THE APPLICATOR HEAD HAS A PLURALITY OF NOZZLES MOUNTED FOR ROTATION UNDER CENTRIFUGAL FORCE TO PROVIDE A CONICAL SPRAY FOR APPLYING THE COATING TO THE WALL AS THE HEAD IS DRAWN THROUGH THE PIPE. A PLURALITY OF CENTERING VANES ARE CARRIED AT CIRCUMFERENTIALLY SPACED POSITIONS ABOUT THE HEAD AND ARE SPRING BIASED TO ENGAGE THE INNER WALL FOR-
摘要:
A method of forming a semiconductor device and the device, the method comprising the steps of providing a silicon substrate of predetermined conductivity type having a layer of silicon oxide with a first mask thereon, implanting a first impurity of the predetermined conductivity type into the substrate in unmasked regions of the substrate, masking the substrate except for a small region immediately adjacent the first mask with a second mask, implanting a second impurity of the predetermined conductivity type into the substrate in the unmasked regions of the substrate to cause some of the impurity to extend in the substrate beneath the first mask, removing the second mask, oxidizing the substrate with the first mask thereon to form a bird's beak extending beneath the first mask with the impurities extending along the bird's beak both beneath and external to the first mask and completing fabrication of a semiconductor device on substrate. The device is a semiconductor device having a silicon substrate of predetermined conductivity type with a semiconductor device structure therein, and a bird's beak region on the substrate wherein the substrate has a higher level of impurity of the predetermined conductivity type along and directly beneath the bird's beak region than in the bulk of the substrate.
