Title: Monitoring device of compressor impeller
Inventor: BUCHER JAKOB
IPC: F04D27/00
Filed: 2002-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a monitoring device of a compressor impeller for predicting an actual service life of the compressor impeller as accurately as possible even when using conditions are changed. SOLUTION: This device is equipped with at least one temperature sensor, a calculator and a memory, and the calculator intermittently finds at least one parameter related to an expected value of the life of the compressor impeller by relating the measured temperature value detected by the temperature sensor with an experiential characteristic data of a compressor impeller accommodated in the memory. The calculator also refers the measured value of the rotational number of the compressor impeller detected by the number of rotations sensor for the purpose of finding one parameter, thereby finding two different parameters, one of which relates to only temperature and the other of which relates to both temperatures and number of rotations. Such parameters show the already-consumed percentage of the expected service life of the compressor impeller at each time.

Abstract: <P>PROBLEM TO BE SOLVED: To provide a radio base station test system for accurately grasping normality of a downlink voice channel.  <P>SOLUTION: A maintenance person uses a fixed phone 2 to utter a voice signal for testing the downlink voice channel. A base station test apparatus 3 receives the voice signal for testing the downlink voice channel arrived via a telephone switch network 1 and a radio base station 4, converts the voice signal into PCM data, and transmits the PCM data to a maintenance console apparatus 5 via a PCM communication channel 6. The maintenance console apparatus 5 receives the PCM data and transmits the received PCM data to a voice reproduction section 52 and a waveform analysis section 524. The voice reproduction section 52 reproduces an audible tone signal from the PCM data and allows a speaker 523 to sound a reproduction sound. The waveform analysis section 524 analyzes the PCM data, obtains noise and waveform distortion caused on the downlink voice channel and displays the result on a display section 525. The maintenance person can accurately evaluate the normality of the downlink voice channel depending on the reproduction sound and the displayed noise and waveform distortion.  <P>COPYRIGHT: (C)2004,JPO
