Every products, which made by mass production, is not identical in their size but have variations in some intervals specified by tolerance dimensions. Tolerances play major role in standardization of part and its quality, and also make a huge impact on manufacturing cost. The optimal condition for tolerances is giving the values as loose as possible for low production cost while satisfying quality specification, which usually demand tight control of tolerances. Tolerance analysis is necessary to get an optimal solution for this conflict situation. This paper have studied tolerance analysis for universal joint assembly of vehicle steering system and tried to find useful results of the study for product design and quality control.

In recent few years, low-power electronics has been a leading drive for technology developments nourished by rapidly growing market share. Mobile DRAM, as a fundamental block of hand-held devices, is now becoming a product developed by limitless competition. To support application specific mobile features, various new power-reduction schemes have been proposed and adopted by standardization. Tightened power budget in battery-operated systems makes conventional schemes not acceptable and increases difficulty of the circuit design. The mobile DRAM has successfully moved down to 1.5V era, and now it is about to move to 1.2V. Further voltage scaling, however, presents critical problems which must be overcome. This paper reviews critical issues in mobile DRAM design and various circuit schemes to solve the problems. Focused on analog circuits, bitline sensing, IO line sensing, refresh-related schemes, DC bias generation, and schemes for higher data rate are covered.

The previous MCC's have the demerits of high cost and much manhour for rework because they are impossible for the standardization of products and have many manual connections. The customers require the products which can operate in connection with SCADA system by digitalizing the functions of the current MCC's and are systematized with capability of remote control. To solve these disadvantages and requirements, we developed the Electronic Motor Control System according to starting type for applying to fields based on this. This system has the various functions such as protection, measurement, and communication. Using these functions, it can monitor motor status through communication with the upper system and define the circuit for lower connection cost according to starting type and shorter manufacture period by program. The development of this product results in establishment of competitive structure with domestic competition and perfect automatic monitoring through linkage with SCADA system. In addition, it provides the comparable dominancy of receiving on orders in switch gear and adaptability to change of MCC market in Japan and Europe.

Kampilla is an important herbal drug of indigenous system of medicine. Fruit dust of Mallotus philippensis Muell-Arg constitutes the genuine drug Kampilla. However, due to limited distribution of this plant and its high medicinal value, the drug is heavily adulterated with the cheaper substances. Hence the present study was undertaken to evaluate both the authentic and market samples. The drug consists of resin glands and trichomes. Resin glands are lined by a delicate yellowish thin membrane and bear a pore at the tip. Quantitative standards of the drug powder showed 82.50% yield in total ash while alcohol soluble extract of market and authentic sample exhibit 0.97% and 3.458% respectively. The main adulterant noticed in the market sample is brick powder. Simple methods are suggested to identify the genuine drug.

None of us need to be reminded that these are exceedingly times. The evidence in all about us. Between rising costs and lowering prices, many businesses find profits being depressed almost to the vanishing point. The eating out food business is in just such a profit squeeze. Our ability to compete depends not only on our ability to control the price-cost picture, but to improve its kitchen product system. A kitchen product system is incomplete without a series of built-in improvement procedures. They must be a key part of the system. "improvement" means the continual betterment of all aspects of the operation-its personnel, products, sales, and its costs. These improvements create profits. This study is devoted to a discussion of the application of research methods and techniques to develop of modern kitchen system through the job standardization. Their use in executing other responsibilities related to the process of kitchen system improvement will also be seen. The steps of setting objectives, gathering data, analyzing and interpreting data, and arriving at solutions, conclusions, and/or recommendations are briefly out lined. The material presented emphasizes the need for an improved and systematic approach to the study of problems. It is also implied, of not stated, that the process should not become so mechanical that the principles of creativity are violated. The foregoing steps suggest a systematic approach to kitchen system improvement, finding solutions to problems, improving work methods, instituting changes, followting up on work related to the change. This study has been limited to the truly important points related to each step in the process, it will undoubtedly call to mind other factors for consideration, however, believe that the principles and approach suggested in this study will bring about better methods and improve kitchen operating results.g results.
