Patent JP-2003501642-A (JP)
IPC: G01F11/04
Filed: 2000-06-07
Abstract: A metering device contains a rotor which defines elongate chamber, there being a shuttle contained within the chamber movable between two terminal end positions. Frusto-conical surfaces defined on the rotor cooperate with annular members defining corresponding seats. One passage extends from one end of the chamber to one frusto-conical surface, and another passage extends from the other end of the chamber to the other frusto-conical surface. Each annual element defines a respective inlet and outlet for fluid and a shuttle is present within the chamber. As the rotor rotates, the shuttle effects a shuttling movement thus measuring dispensed volumes of fluid. A sensor is provided to detect physical contact of the shuttle with the end of the chamber to cause the rotor to advance.

IPC: F01D25/00
Filed: 2002-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting vibration by using amplitude modulation or frequency modulation of a pulse train. SOLUTION: A machine such as a gas turbine 203 includes a rotor 208 for supporting a gear 4. A sensor 8 positioned nearby generates the pulse train 72 with passage of a tooth 16 of the gear 4. The frequency of the pulse train 72 shows the rotational speed of the rotor. In addition, vibration of the rotor 208 allows the gear 4 to perform orbital motion with another center. The orbital motion generates the amplitude modulation or the frequency modulation of the pulse train 72, or both modulations. Detection of the modulation indicates existence of the vibration. In this way, both the speed and existence of the vibration are indicated by using one pulse train 72 generated by one sensor 4.
