According to the results of the studies on 23 references, the orders in the cause of Liver-Exhaustion (肺勞) were as follows ; 1) Liver-damage (肺傷) was the most abundant by occuping 26.09% (6/23) 2) Trouble-resources-prudence (勞力謀慮) and Liver-deficiency (肝虛) were the second by occuping each 21.74% (5/23). 3) Spirit-damage (神損) was 13.04% (3/23) and Anger-counter-up (怒氣逆上) was 8.70% (2/23). The Orders in the cases of Liver-exhaustion (肝勞) were as follows ; 1) Dry-dark-countenance (面目乾黑) was the most abundant by occuping 34.79% (8/23). 2) Spirit-unstableness (精神不守) was the second by occuping 30.43% (7/23) 3) Sight-unclearness (目視不明) was 20.09% (6/23) 4) Muscle relaxation not maintained by oneself (緩不能自收指) was 21.74% (5/23) Other various cases were excepted because of low frequence.

Apartment and large residence buildings are necessary to ensure a comfortable noise/vibration environment. So. it must be performed a anti-vibration/noise evaluation at early design stage, such as utility room arrangement, machinery installation method and so on. In this paper. environment noise status on problem areas, which was issued by resident. was investigated to understand the noise transmission property generated from underground machinery room and to device a optimized countermeasure in order to enhance noise environment. Also, the measured noise levels before and after modification works are compared to confirm the effectiveness of proposed countermeasure.

The magnetic levitation system is utilized in the magnetic bearing of high-speed rotor because of little friction, no lubrication, no noise and so on. The magnetic levitation system need the feedback controller for the stabilization of system, and gap sensors are usually used to measure the gap. The use of sensor is troublesome such as sensor trouble, discord between the measurement point and the control point etc. This paper presents the design of robust stabilizing controller by H$_{\infty}$ control theory using the sensorless method proposed already by authors in the magnetic levitation system. And we investigated both the validity of the designed controller and the usefulness of the sensorless method proposed by authors of magnetic levitation system through results of actual experiment..

Vertical canned pumps are usually applied in the power plant to transport fluids that the available suction pressure is low at the condensate system and the circulating-water system. The top of the motor driver is 5.5m above the base and the barrel and drop column extend even further below the ground. While this size and configuration may produce an efficient pumping system, it also introduces several dynamic problems which must be considered in order to obtain a reliable operation. The main problem is that the vibrational mode of the long flexible cantilever structure above the ground exist near the operational characteristics of the condensate debris system. This system's trouble has been showed at 2,086 hp condensate water loading pumps in a nuclear power plant.

The paper is an outline of development of vibration troubleshooting database on Web Browser which has been able to connect with the Internet. When the vibration trouble have occurred in industrial field, most important matter is that how to solve it. We expect it effective to solve the matter to develop a case base system. The System is expected that the access speed will be fast to connect with the Internet and the user will be free from to learn search queries to use graphical user interface(WWW) as a search interface.

The vibration reduction process for the driver comfort of a forklift truck is studied in this study since the related driver comfort is a primary design target in the vehicle design recently. However, the underlying study for a vibration analysis regarding to the driver comfort is still an element stage. Thus, a preceding large work has to be needed to apply the CAE technology for the detail vehicle design, and it prevents the vehicle optimal design. To reduce the proceeding large works, the evaluated process and required data are comply with the accumulated trouble shooting experiences in this study. Since the driver comfort is a human related problem, the human vibration index associated with analysis vibration result is additionally introduced as a driver comfort judgement value.

A company needs to maintain its machines always workable in order to keep the manufacturing time minimal. If any troubles un, they should be fixed as soon as possible. But, the complexity of modem machines make the trouble shooting difficult. So, it is important that the monitoring system for automated production system to fix every trobule easily. In this paper new, inverter control system for TG feedback a formula Control was developed. The motor control system with TG feedback controller as an effect of load disturbance, it is very difficult to guarantee the robustness of Control System. The function of the implementation are TG feedback type, and temperature scheme. The Inverter Control System approach is based on master-slave control concept. To show validity of the developed new inverter control system severial experiments are illustrated.

The SSPA makes the power level of EIRP up to 16W, and compensates for temperature to the SSPA´s maximum stability. The up and the down converters are dually conversed like as individual synthesizers for selecting of independent transmit-receive transponder. The function of the up-converter is to convert the 70MHz IF signal modulated in the indoor unit modem into a 14.0 ∼ 14.5 GHz Ku-band up-link signal to be sent to the antenna. The down-converter converts the 12.25 ∼ 12.75 GHz Ku-band down-link signal or a trouble malfunction of SSPA may be a fatal factor to operation of the whole satellite communication network. Therefore, this study developed the remote monitoring and control program to monitor the SSPA´s status before the problem occurs for stable operation of the system. This software ...

Harmonic current originating from electric locomotives can be magnified due to the impedance characteristics of power supply circuit and bring about various problems. That is, electromagnetic interference with communication lines, operational trouble in signaling, overheat and/or vibration in power capacitor, mis-operation in protection relay and so on. Therefore, the exact assessment of the harmonic current flow must be undertaken at design and planning stage for the electric traction systems. for these reasons, this study propose a new approach to model and to analyse traction power feeding system focused on system response to current and voltage harmonic(PART I). Measurements of harmonics are also performed for railway power supply systems under normal operation. Spectrum and distortion analyses in measurement data are variously described in PART II.

The notion of object oriented analysis and design in software engineering has many rewards that aid the programmer to have an understanding of and improve the program efficaciously. Object oriented metrics helps rather a lot to a programmer or developer to comprehend and unravel the thing-oriented trouble readily and exactly. Object oriented metrics helps in examining the usefulness of object oriented applied sciences or in simple phrases Object-oriented metrics depict characteristics of object-oriented programming. The intention of this paper is to have an understanding of concerning the UML, Object oriented evaluation and design and the way it plays in UML.
