Patent number: 6336714Abstract: Described herein is a monolithic printhead formed using integrated circuit techniques. Thin film layers, including ink ejection elements, are formed on a top surface of a silicon substrate. The various layers are etched to provide conductive leads to the ink ejection elements. At least one ink feed hole is formed through the thin film layers for each ink ejection chamber. A trench is etched in the bottom surface of the substrate so that ink can flow into the trench and into each ink ejection chamber through the ink feed holes formed in the thin film layers. The trench completely etches away portions of the substrate near the ink feed holes so that the thin film layers form a shelf in the vicinity of the ink feed holes. In one embodiment, the shelf supports the ink ejection elements. An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers.Type: GrantFiled: August 27, 1999Date of Patent: January 8, 2002Assignee: Hewlett-Packard CompanyInventors: Naoto A.

Patent number: 6305324Abstract: A housing system for aquatic animals has a shelf-like rack holding tiers of individual tanks or aquariums (aquaria), each removably suspended from structural members that engage flanges of the tanks. The tanks are tilted inwardly of the rack and have covers with fittings on the higher or outer side, that intercept flow between a supply and a drain to inlet water when the tank is in the rack and to recycle the water at any tank position that is unoccupied. The inside bottom of each tank is contoured, for example with a longitudinal trough, so sediment collects at a low spot on the lower or inner side, where a drain inlet is placed to provide a drainage outlet that opens at a velocity increasing restriction at which sediment is entrained. The drain has a spring biased valve that opens the drain only when the tank is fully inserted in the rack.Type: GrantFiled: November 5, 1999Date of Patent: October 23, 2001Assignee: Thoren Caging Systems, Inc.Inventors: William J.

Patent number: 6300762Abstract: The present invention relates generally to the use of polyaryletherketone-based thermoplastic materials in high pressure, high temperature, production logging applications. A polyaryletherketone resin bonded with glass fibers is formed into a housing for formation evaluation sensors permanently located downhole. The housing is constructed by any of the following processes: filament winding, fiber placement, or compression molding or injection molding. When used in a production well, the housing encloses the formation evaluation sensors and protects the sensors from borehole fluids. Housing properties can be modified with changes in materials added to the resin in order for the housing to function as casing or coiled tubing. This would allow wireline or logging-while-drilling conveyed sensors passing through the casing or coiled tubing to sense the formation and borehole fluid properties.Type: GrantFiled: July 29, 1999Date of Patent: October 9, 2001Assignee: Schlumberger Technology CorporationInventors: Stanley R.
