The conventional ultrasonic inspection is a detection of the ultrasonic wave reflected at the abnormal points in an inspected object. However, the ultrasound passes through an indistinct or minute abnormality. The conventional ultrasonic inspection is unavailable to detect them. In this paper, the authors focus their attention to frequency modulation of the ultrasonic wave, and attempt to detect the minute abnormality by using it. In the proposed method, the frequency modulation is observed as a variation of instantaneous frequency of the ultrasonic wave, and the instantaneous frequency is defined as the derivative of a time-dependent phase angle of the ultrasonic wave. In the case that the indistinct or minute abnormality exists in an object, the authors find that the instantaneous frequency of the ultrasound passing through the abnormality deviates from usual frequency level. Therefore, the abnormality can be detected by the variation of the instantaneous frequency, that is, the frequency modulation. It is difficult for the usual Fourier transform to catch the modulation because of a limitation of a frequency resolution. A feasibility of the proposed method is demonstrated through a simple experiment.

Nowadays, Kaizen technology has been widely utilized as one of the tools of Kaizen activity. However development of it has been mostly performed under the support of experts which have the know-how to apply Kaizen technology. One relevant way to realize the progress of Kaizen activity without their support is to establish an approach enabling systematic technology development. In this paper, especially focusing on Visual management technology as one of the Kaizen technologies, a technological level of Visual management technology as one guideline of the approach is discussed. The proposed technological level consists of the following six levels from primitive level to advanced level: (1) visualization of unusual phenomena, (2) visualization of root cause, (3) visualization of spill-over effect, (4) visualization of procedure to cope with the problems, (5) visualization of real time action sequence for problem solving and (6) visualization of 100% normality. Two case studies are performed to assure the relevance of the proposed level by focusing on Kaizen projects of chemical plant. Then the proposed technological level is qualified by experts as useful method for education/training against manufacturing workers through collaboration with a factory eager to implement Visual management technology.

The practice of engineeringmanagement has been around for hundreds, if not thousands, of years. However, the academic discipline of engineeringmanagement has existed for a little over forty years. engineeringmanagement was established as a M.S. program in 1965 at the University of Missouri- Rolla (now Missouri S & T). Today there are over 70 universities offering this important degree in the United States. In Europe, engineeringmanagement education is generally linked with Industrial engineering. The largest engineeringmanagement organization in Europe is ESTIEM. In China, engineeringmanagement was introduced as an academic discipline in the mid-1980's according to Dr. Zhongtuo Wang of Dalian University of Technology. Today there are over 150 universities offering engineeringmanagementprograms in China.
