ジャーナル フリーThe optimization of quantitative analysis for infrared spectroscopy was conducted through quality engineering approach. Linear Multiple Regression Model was used for the estimation of mixture component ratios. Several samples of polystyrene-polymethylmethacrylate blend polymer were accurately prepared and experimentally quantified as the signal. SN ratio was used for the evaluation and significant control factors such as absorption band and its region were determined. A gain of 4.36 decibel was confirmed from this study.抄録全体を表示PDF形式でダウンロード (1526K) -

ジャーナル フリーThe dry developer used for electro-photographic copiers and printers is consisted of toner and carrier. There are various kinds of developer depending on the process and application. This report describes the analysis in order to improve the efficiency of a fine grinding process for developer using the dynamic operating window in Taguchi Methods. This manufacturing process controles particle size of developer. Particle size is one of the pysical properties for dry developer and has a great influence to image quality. As a result, we could improved the efficiency of this process.抄録全体を表示PDF形式でダウンロード (1493K)

ジャーナル フリーOptimization of NC Machning for Stainless Steel by a Trainee form Brazil Juio Cesar Bento Ribelro who teaches at a technological college in Brazil came to shiga Province Industrial Technology center as a trainee for three months. He was interested in the robust design using quality engineering approach and selected a project of stainless steel processing for study,Most of the manufacturing plants in Brazil are not automated and product quality highly depends on the skilled labor, Therefore, the introduction of quality engineering methods in Brazil has an important significance. Test pieces were used for the processing and dynamic SN ratio was used for quality evaluation, as a result, a gain of 15.8 decibel was confirmed, which is equivalent to a 6.2 fold reduction in standard deviation.抄録全体を表示PDF形式でダウンロード (1420K) -

ジャーナル フリーThe sensory evaluation is used in many cases for the development of consumer products. Especially, it is important to the first stage for the development of products, so that high quality of customer satisfaction may be achieved. ln this report, S/N ratio applied in sensory evaluation that make a comparison with the quality, by way of example the lead for mechanical pencils. I would like to talk about the things applied to solve the problem in sensory evaluation by using Quality Engineering methods.抄録全体を表示PDF形式でダウンロード (1374K)
