  • Publication number: 20030110802
    Abstract: 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.

  • Publication number: 20030110803
    Abstract: There is provided a method of manufacturing a glass substrate for magnetic disks, according to which circumferential direction texture can be formed without bringing about a drop in anisotropy, thus enabling coating with a magnetic recording layer having a large magnetic coercivity. In a texturing step, a tape is used while a diamond slurry is fed onto at least one main surface of a glass substrate member that has been processed into a substantially circular shape, thus forming a linear texture in a circumferential direction on the at least one main surface. In a chemical strengthening step, the mechanical strength of the glass substrate member is chemically strengthened to a level required of the glass substrate for magnetic disks. The texturing step is carried out after the chemical strengthening step.

  • Publication number: 20030110829
    Abstract: The invention relates to a method and a device for the extractive triboelecric measurement of dust and aerosols. A partial gas stream is removed from the main stream, optionally conditioned and drawn through the triboelectric measuring chamber (5) by suction, with a variable or constant temperature, at a variable or constant speed and with an abradant rotational movement. Sensors (16) are arranged in said measuring chamber (5) in such a way that they are electrically insulated. The triboelectric effect begins when the gas stream that is loaded with dust particles and aerosols passes through the triboelectric measuring chamber (5), preferably in a cyclonic manner, moving rotationally, abradantly on the sensors (16). The triboelectric measuring signals are derived therefrom and supplied for processing. Since gaseous components cannot be measured according to the triboelectric measuring principal, the temperature is controlled intermittently at two temperatures in the chamber.

    Abstract: Methods and apparatuses for testing the compliance of stents and stented grafts, including pre-testing them in a pre-tester tube prior to accelerated fatigue testing. The pre-tester tube is a simulated human vessel that may be made of animal tissue having approximately the same size as the human target vessel. The pre-test involves pressurizing the pre-tester tube at various normal and abnormal physiologic pulsed pressures with the stent or stented graft in place. By measuring the expansion of the pre-tester tube, the proper expansion rate of the stent or stented graft is determined. Those data are then used in a feedback loop to control the amount of expansion of a synthetic tester tube in the accelerated fatigue tests. The tester regulates the pressure in the tester tube to attain the proper expansion magnitude during the test. The animal tissue may be porcine tissue, in particular a porcine aorta to simulate the human abdominal aorta. Any side branches of the porcine aorta are tied off.

  • Publication number: 20030110841
    Abstract: 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.

  • Publication number: 20030110845
    Abstract: 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.
