  • This is the Study on Application and Manufacture Technique of Cold-Mix, Cold-Laid type Asphalt Concrete using of Polymer modified asphalt the could be constructed easily and economically on damaged road repaireless for seasons. The modified materials for this study are SBS(Styrene-Butadiene-Styrene). SBR (Styrene-Butadiene-Rubber) and PUR(Polyurethane). The Marshall stability and the value of flow and resistance in water stability degree according to the alternation types and weight percent of modified materials were compared and evaluated on this study. The results of the study show that PUR modified asphalt have improvement of over 150% Marshall stability in AI MS-14 standard and they are evaluated to have the easiness of storage and better working efficiency compared with other types of modified asphalt compound.

  • This study was performed to manufacture guarasulgies for using in diet therapy by adding various ingredients (mugwort, Angelica gigantis Radis, cinnamon, cocoa powder) to decrease the flavor of guar gum itself and enhance the texture of guarsulgies. The sensory characteristics of guarsulgies added these ingredients wee investigated to decide the maximum acceptable addition levels. The maximum acceptable addition levels of these ingredients was 3.75% for mugwort, 3% for Angelica gigantis Radis, 2% for cinnomon or 0.75% for cocoa. In the texturemeter measure for guarsulgies added cocoa, springness, gumminess, hardness, and chewiness tended to increase compared to other guarsulgies. We concluded that guarsulgies added mugowrt, Angelical gigantis Radis, cinnomon, and cocoa would be much better sanacks for diabetes and obese people than plain guarsulgies.

  • We investigate the qualities of organic materials by which can manufacture organic thin films for solar cells and make thin films for insulation layers of an insulated cable. We give pressure stimulation into organic thin films and detect the induced displacement current. In processing of a device manufacture, We can see the process is good from the change of a surface pressure for organic thin films and transfer ratio of area per molecule. The structure of manufactured device is Au/organic thin films(polyimide)/Au and I-V characteristic of the device is measured from 0[V] to +5[V]. The maximum value of measured current is increased as the number of accumulated layers are decreased. The resistance for the number of accumulated layers, the energy density for an input voltage show desired results, and the insulation of a thin film is better as the interval between electrodes is larger.

  • Nano manipulator is used to manufacture Carbon NanoTube(CNT) tips. Using nano manipulator operator attaches a CNT at the end of Atomic Force Microscopy(AFM) tip, which requires a master mechanic and long manufacture time. Nano manipulator is installed inside Scanning Electron Microscopy (SEM) chamber to observe the operation. This paper presents a control of horizontal axis of nano manipulator via processing SEM image. Edges of AFM tip and CNT are first detected, the position information so obtained is fed to control horizontal axis of nano manipulator. To be specific, visual servoing loop was realized to control the axis more precisely.

  • In this paper, we discuss the development of monitoring system with data process equipment which transfers data from Remote Terminal Unit(RTU) to monitoring computer. The RTUs sense temperature, pressure and PLC(Programmable Logic Controller) nodes conditions of scrubber in semiconductor manufacture processing. The data Process equipment is connected every RTU and a monitoring computer through serial communication. This equipment receives informations from RTU, process data, and transfers them to monitoring computer. To avoid congestion in data communication, task scheduling algorithm used RT O/S(Real-Time Operating System) is embedded in ROM which is a part of data Process equipment.

  • The major part of SMES (Superconducting Magnetic Energy Storage) system consist of the superconducting coil, cryostat and current lead, power converter. The 0.7MJ SMES coil was a design and manufacture by using SMES device that we developed a design code. A SMES coil was wound with high winding tension in order to prevent wire motion from Lorentz force. This paper described optimum design for the SMES coil.

  • The purpose of this study is to investigate the compressive strength and mixing properties of the lightweight block, which has been manufactured without the pre-wetting process, in the lightweight block using domestic artificial lightweight aggregate. The test results of the specimens produced within 30 minutes after the preparation showed high compressive strength but poor permeability. Therefore, the elapsed time after the manufacture, which is expected to have required compressive strength and permeability, was about 60 minutes in this study.

  • Manufacturing process of plugs is firstly performed in the making of FRP yacht so it is an essential process for making original form. In the developed countries, it has been useful to manufacture structures of streamlined forms or complex forms, which have been difficult to manufacture due to limits of the traditional hand-made technology, by introducing 5-axis machining technology. In this study, the factors that affect most in the machining were found by using Taguchi Method in order to select the optimized machining conditions for 5-axis machines, and the ways to improve the surface roughness of machined products by applying those factors.

  • In industry, several casting process are widely used to manufacture complex and accurate blank part of hard materials such as aluminum, casting steels, bronze and magnesium alloys which are difficult to manufacture in a blank shape. Even if the casting process does not high accuracy superior surface characteristics other machining process, the casting process is widely used in manufacturing blank part. Furthermore, it is difficult to select appropriate casting process a part among several casting process. for effective selection different process, a careful decision given casting application is necessary. An appropriate casting for a given material and shape condition must be selected for novice engineers in industry. In this paper, an expert system based on an analytic network process(ANP) is suggested for best selection of casting considering a prior interdependency effect among various factors such as material, geometry, process capability, economy and equipment.

  • The most important thing in the garments enterprises is fast reaction. Expecially in the China has both many population and large territory, so each region of China, for instance, northeast, northwest, huanan, huabei, has various climate and considerably different temperature. As a result China garments enterprises require different clothes at the same time. This study build a reliable market-response process as a sub module of SCM that lay emphasis on production and sale cope with specific character of China. This process build a information chain including manufacture-planning, manufacture-ordering, production, arrivals of goods, distribution, sale, sale-evaluation, cross shipment, supplement shipment, and ordering popular goods and similar products. As a result of those, the focused points of this process are real time data gathering and various analysis of data, so it can be possible supporting more faster and more accurate market decision making system and our proposed goal is accomplishment of management profit.
