| 20100321195 | LOOSE PART MONITORING METHOD AND SYSTEM - A loose part monitoring method and system for preventing the generation of a false alarm as much as possible, including analyzing a group of detection signals that have been output from a plurality of sensors placed on a wall defining a fluid flow path, wherein the group of detection signals are analyzed for a rising gradient that is related to change in intensity of impulsive sound, a damping time that is related to change of intensity of the impulsive sound, and a frequency spectrum that is related to pitch of the impulsive sound in order to determine whether the group of detection signals are false or true. | 12-23-2010 |
| 20090148610 | Anticorrosion Coating Method for Zinc-Plated Steel Structure - The present invention provides an anticorrosion coating method for a galvanized steel structure, the method comprising applying an undercoating composition (I) to a cured thickness of 10 to 200 μm to a surface of a galvanized steel structure, and then applying thereto an overcoating composition (II) to a cured thickness of 100 to 1,500 μm;

| 20090126511 | Torque measuring method and apparatus for motor-operated valve - A torque measuring method and apparatus for a motor-operated valve including a valve driving mechanism operable to open and close the valve, a worm displacable by driving of the motor to operate the valve driving mechanism, and a spring cartridge having a plurality of belleville springs and disposed coaxially with the worm for compression by the worm. The method comprises obtaining basic data representing a relationship between the amounts of compression of the belleville springs and the torques exerted, measuring a displacement of the worm or the spring cartridge and acquiring, from the thus obtained displacement of the worm or the spring cartridge, a real amount of compression of the belleville springs in which an influence of a play of the spring cartridge has been removed, and substituting the real amount of compression for the amount of compression of the basic data to acquire a real torque corresponding to the real amount of compression. | 05-21-2009 |
| 20090013752 | Method and apparatus for diagnosing motor-operated valve - A diagnostic method and apparatus for diagnosing a motor-operated valve capable of continuously measuring a preload of a spring cartridge at low costs, with high accuracy, and with ease, so that the elastic characteristics of the spring cartridge may be easily calibrated in a simple manner. The method and apparatus is for diagnosing a motor-operated valve including a valve disc | 01-15-2009 |
