    Abstract: Three or more glass particle synthesizing burners are arranged to be opposed to a rotating glass rod. The glass rod and the glass particle synthesizing burners are reciprocated in parallel and relatively to deposit glass particles synthesized by the burners on the surface of the glass rod, thereby producing a soot body. The glass particle synthesizing conditions of the burners arranged at both ends are changed to have a greater deposition amount of glass particles per unit time in part or all of its movement range than other burners.

  • Publication number: 20030070451
    Abstract: A method of making optical quality films is described. A silica film is deposited on a wafer by PECVD (Plasma Enhanced Chemical Vapor Deposition). The deposited film is then subjected to a first heat treatment to reduce optical absorption, wafer warp, and compressive stress. A second film is deposited. This step is then followed by a second heat treatment to reduce optical absorption, wafer warp and tensile stress. The two heat treatments have similar temperature profiles.

    Abstract: An adjusting apparatus and method for automatic setting of injectors are disclosed. The setting is carried out via accurate adjustment of the distance between an actuator and a lever element. In the process, an injector to be set is provided in the correct position in a measurement and setting station and is coupled to a pressure generating device. The setting element of the injector is then rotated in such a way that the injector switches through at a specific setting of the setting element. At the same time, the current values for the torque applied to the setting element, for the angular position of the setting element, for the exciter voltage applied to the actuator and for the pressure drop caused by the switching-through action are registered and compared with predefined parameters. If all the measured values agree with the predefined parameters, then the injector has been set correctly.

  • Publication number: 20030070472
    Abstract: The present invention provides a method for easily measuring nitrogen oxide concentration of an engine vehicle emission. The method can measure vehicle emission from an engine of a vehicle in travel with high precision even in regions other than the lean region, that is, regions from the stoichiometrical region to the rich region by using a NOx sensor exclusively used for the lean region. The present invention has an arrangement in which a NOx sensor that is exclusively used for the lean region is installed in an exhaust pipe 3 connected to the engine 2. Air (secondary air) A is introduced into the exhaust pipe 3 on the upstream side of the NOx sensor 6 so that the NOx sensor 6 is allowed to measure the concentration of NOx in the engine vehicle emission diluted by air A. Thus, the NOx concentration in the engine vehicle emission before dilution G is obtained by using the measured value of the NOx concentration after dilution and by using a dilution ratio.

  • Publication number: 20030070490
    Abstract: A pressure detection device for detecting pressure of fluid that comprises a housing, a pressure-transmission medium, a sensor chip, at least one terminal pin, a sealant and a film. The pressure of the fluid is transmitted to the pressure-transmission medium such as silicone oil, and the sensor chip detects the pressure of the pressure-transmission medium. The terminal pin for the electrical connection between the sensor chip and an outside device is fixed into the housing, and a contact protrusion that is exposed in the housing for being electrically connected with the sensor chip is formed at one end of the terminal pin. The sealant such as poly-monochloro-para-xylylene is put around the contact protrusion for sealing the pressure-transmission medium. The film such as poly-monochloro-para-xylylene for avoiding the contact between the pressure-transmission medium and the sealant is coating the sealant.

  • Publication number: 20030070491
    Abstract: A method for analyzing creep characteristic of a plastic molded substance is provided wherein the creep characteristic can be analyzed of an actual plastic molded substance having various shape and fastening conditions with high precision. The main stress value for each section of the analysis target is read out, hydrostatic stress &sgr;m of each section is calculated from the main stress value, and the stress condition is determined to be tensile stress when &sgr;m is positive and to be compressive stress when &sgr;m is negative. Tensile or compressive characteristic value is assigned based on the stress condition at each section, and creep is calculated for a predetermined time period based on the characteristic value. By employing characteristic values depending on the stress conditions of each section, precision of creep characteristic analysis is greatly enhanced.

  • Publication number: 20030070492
    Abstract: The onset of rolling contact fatigue in an object may be detected by measuring the residual stresses in the surface of the object, and monitoring changes in their magnitude or their direction. The values of residual stresses in the surface are those averaged over a depth that may be in the range say 0.1 mm to 8.0 mm, for example about 2.5 mm. For ferromagnetic objects such as rails, the method may utilise an electromagnetic probe. Prior to rolling contact fatigue the surface stresses are compressive, and the onset of rolling contact fatigue may be characterised by a marked decrease of the stress in the generally transverse direction.

  • Publication number: 20030070499
    Abstract: A bailer having multiple check valves to minimize leakage of sample fluid from the bailer. A primary check valve assembly including a ball and a seat are disposed at a lower end of the bailer. At least one auxiliary check valve assembly is positioned above the primary check valve assembly. When a first auxiliary check valve closes, the hydrostatic pressure applied to the primary check valve is reduced significantly and leakage through the primary check valve is reduced. When a second auxiliary check valve closes, the hydrostatic pressure applied to the first auxiliary check valve is reduced and the same benefits are obtained for the first auxiliary check valve. Particulate matter is collected in an annular trough formed in the primary check valve assembly and in pockets that form a part of each auxiliary check valve assembly.
