Publication number: 20030110802Abstract: A method of adjusting the pH of a strengthening melt for use in strengthening glass substrates, e.g., glass disk substrates for use in data storage devices. A non-particle-forming acid is added to the strengthening melt to lower the pH of the strengthening melt to ≦8. The acid is added while the strengthening melt is in a molten state and selected to avoid particle formation. Nitric acid, for example, is non-particle-forming with respect to nitrate based strengthening melts such as potassium nitrate and/or sodium nitrate. A base, e.g., sodium hydroxide, may be added if the pH of the strengthening melt falls below 5. Strengthening melts are subject to pH shift that can cause glass substrates strengthened therein to etch, creating pits on the substrate surface. Glass disk substrates treated in the pH adjusted strengthening melt are essentially free from such pits, as well as contamination caused by particle formation.Type: ApplicationFiled: December 18, 2001Publication date: June 19, 2003Inventors: Terry Lee Jensen, John William Marier, Rick Allan Sprague

Publication number: 20030110841Abstract: In an operating liquid feed fuel cell system, fuel concentration in the fuel stream can be calculated as a function of the observed current, the temperature of the fuel stream entering the fuel cell stack and the temperature of the fuel cell stack itself, thereby eliminating the need for a separate sensor. Typically, methanol will be used as the fuel and the liquid feed fuel cell system will thus be a direct methanol fuel cell system.Type: ApplicationFiled: December 19, 2001Publication date: June 19, 2003Inventors: Jiujun Zhang, Kevin M.

Publication number: 20030110842Abstract: The invention is in a method of analyzing the water of an industrial water system wherein an analytical device is used to measure some parameter capable of being measured in the water of said industrial water system, the improvement involving using a water movement device that is capable of moving a sample of water into the sample chamber of said analytical device and is also capable of moving the same sample of water back out of said analytical device in a manner such that the filters present in the piping of said industrial water system are back flushed out every time the water movement device moves a sample of water in and out of said analytical device. Optionally an air sparge is used to enhance the cleaning of the filters.Type: ApplicationFiled: December 13, 2001Publication date: June 19, 2003Inventors: Jitendra T. Shah, Brian S. Johnson

Publication number: 20030110843Abstract: The invention relates to a measuring sensor (1) for measuring positive and negative elongations on cylindrical or profiled bodies (6). The measuring sensor (1) consists of more than two parts and is essentially annular and has at least one tensioning element (7, 15). Two segments (2, 3) that can be tensioned are provided with a recess on the longitudinal center on the internal contour (22), the recess being disposed opposite the direction of tensioning (S) and accommodating a protruding elastic element (8) with a measuring element (10). The recesses can be pressed non-positively onto the surface of the body (6). The segments (2, 3) of the multi-part measuring sensor (1) that are diagonally opposite can be tensioned with their both ends by means of exchangeable and/or adjustable lateral guide members (4, 5, 26, 38) for the body to be measured (6).Type: ApplicationFiled: October 29, 2002Publication date: June 19, 2003Inventor: Matthias Tanner

Publication number: 20030110844Abstract: A force scanning probe microscope (FSPM) and associated method of making force measurements on a sample includes a piezoelectric scanner having a surface that supports the sample so as to move the sample in three orthogonal directions. The FSPM also includes a displacement sensor that measures movement of the sample in a direction orthogonal to the surface and generates a corresponding position signal so as to provide closed loop position feedback. In addition, a probe is fixed relative to the piezoelectric scanner, while a deflection detection apparatus is employed to sense a deflection of the probe. The FSPM also includes a controller that generates a scanner drive signal based on the position signal, and is adapted to operate according to a user-defined input that can change a force curve measurement parameter during data acquisition.Type: ApplicationFiled: December 6, 2001Publication date: June 19, 2003Applicant: Veeco Instruments Inc.Inventors: Jens Struckmeier, Doug Gotthard, Ben Ohler

Publication number: 20030110845Abstract: A failure determination system and method for an internal combustion engine and an engine control unit are provided which are capable of properly determining a failure of a variable valve mechanism for inactivating a valve system associated with at least one of cylinders during a predetermined operation of the engine, by discriminating a misfire caused by the failure of the mechanism from a normal misfire. Fuel injection valves inject fuel for each cylinder and oxygen concentration of exhaust gases is detected. A misfire condition is detected on a cylinder-by-cylinder basis. Fuel injection to a misfiring cylinder is stopped. A failure of the mechanism is determined, when a parameter based on the oxygen concentration detection indicates a richer value of an actual air-fuel ratio of the exhaust gases than a predetermined reference value does, under a condition of the fuel injection being stopped.Type: ApplicationFiled: December 12, 2002Publication date: June 19, 2003Applicant: HONDA GIKEN KOGYO KABUSHIKI KAISHAInventors: Katsuhiro Kumagai, Shinichi Kitajima, Futoshi Nishioka, Toshinari Shinohara, Kan Nakaune, Atsushi Matsubara

Publication number: 20030110846Abstract: A device (20) is used for measuring the injection quantity of injection nozzles (30). It includes a measuring chamber (22) to which the injection nozzle (30) can be coupled. In addition, a detection device is provided, which detects a state change of the testing fluid (60) in the measuring chamber (22) due to an injection by the injection nozzle (30). In order to be able to measure the injection quantity without wear and in a highly precise manner, the invention provides that the detection device has a capacitor, whose one electrode is comprised of an electrically conductive fluid (62), which is at least partially contained in a volume connected to the measuring chamber (22). The processing unit (58) is connected to the capacitor in such a way that it can detect a change in its capacitance, which is produced by a movement of the electrically conductive fluid (62).Type: ApplicationFiled: October 25, 2002Publication date: June 19, 2003Inventors: Eberhard Schoeffel, Hans Braun, Fabian Lafrenz, Josef Seidel

Publication number: 20030110847Abstract: Provided herein is a non-contact type rotational position sensor which is allowed to achieve intensification of parts, miniaturization, simplification of assembly, and higher accuracy. A rotor (a permanent magnet) is mounted on a rotational shaft. A Hall IC is interposed between an upper stator and a lower stator which are magnetic plates. The Hall IC is sensitive to magnetic flux density which varies according to a rotational position of the rotor. In a housing incorporating the rotor and the Hall IC is provided integrally a connector provided with an external connection terminal. Conductors for connecting external connection terminals and input/output terminals of the Hall IC are embedded into the housing by insert-molding. One ends of conductors are exposed at a fixed position where the input/output terminals are present. The terminals of the Hall IC are guided by a guide and joined to the one ends of conductors.Type: ApplicationFiled: September 27, 2002Publication date: June 19, 2003Applicant: Hitachi, Ltd.Inventors: Masanori Kubo, Hitoshi Andoh, Kenji Ono, Yasuo Saito, Satoshi Yamazaki
