This paper is described about applied method of personal computer for clothes-patterns. The personal Computer (Fijitsu FM-$16{\beta}$) and X-Y Plotter (GRAPHTEC GP-9101 R) were used in this study. It is studied to draft of sleeve designs automartically in this paper. The Basic Language is used and the programs were main program and subroutine programs. The results are as follows; 1) The Y's system of sleeve sloper is selected in this study. 2) The co-ordinate points were indicated relative location of all necessary in drafting of sleeve designs. 3) In the variations of sleeve sloper, Puff sleeve and Raglan sleeve were selected. Programs for drafting of them were developed. 4) About the drafting of Raglan curve, it is gotten adequate curve using sprine function. 5) Clothes-Pattern are making very correctly and quickly by using computer.

An Internet-based dynamic analysis system, called P-DYN, for multibody dynamic systems is developed. All the interfaces of the system are accessible via Web browsers, such as Netscape or Explorer. The system uses a template type P-DYN/Modeler as a preprocessor. The P-DYN postprocessor composed of P-DYN/Plotter and P-DYN/Animator is developed in JAVA. The P-DYN/Solver for predicting the dynamic behavior is run on the server. Anyone who wants to analyze the dynamics of multibody systems or share results data can access the analysis system over the Internet regardless of their OS, platform, or location.

Radar image data were collected through the on-line data acquisition system of A/D converter and personal computer, and the image was restorated on CRT or plotter after digital image processing of the data. The digital image processing system which was developed for this study, consisted of some kinds of software as follows : rearrangement, transformation, and enhancement of the image data in real space or frequency space by Fourier transform, edge detection of the image, compact processing, state inferential processing, and so on. Since the image of PPI radar sweeps from the center to the circumference of a circle, the image within a given period has the shape of fan. Therefore the acquired data were transformed to have the same interval as that of data in outmost concentricity. The results of various image processing methods using transformed data were better than those of the methods using original data.

The purpose of this research was to utilize of Pattern Design System(P.D.S) by using AM-300 The conclusion were like these : 1. A coat of basic pattern was selected by design sketch. 2. The basic pattern was input into computer by digitizing. 3. The basic pattern was change into designed shape by using various skills. This system were enabled to draw straight lines, curves, delete lines, sections of lines, extend lines, cut pattern into sections, measure line or section reproduce whole pattern shape of section, rotate and mirror pattern and complete patterns. 4. Automatic grading of finished master pattern have been developed by creation and modification of grading rules of basic pattern. 5. Production pattern added seam allowance, not-ches was generated by P.D.S menu option. 6. Finished pattern design was plotted out 100% and 20% size by AM-300 Plotter. This results will be the basic materials to develop the CAD SYSTEM if some problems were improve. Furthermore, the utilization of P.D.S is expected to be developing in pattern making process.

A web-based dynamic simulation system, called O-DYN, for multibody systems is developed. All the interfaces of the system are accessible via web browsers, such as Netscape or Explorer. The system uses a block-diagram type O-DYN/Modeler developed in JAVA Applet as a preprocessor. The O-DYN postprocessor composed of O-DYN/Plotter and O-DYN/Animator is developed in JAVA Applet. The O-DYN/Solver for predicting the dynamic behavior is run on the web server. Anyone who wants to simulate the dynamics of multibody systems or share results data can access the analysis system over the internet regardless of their OS, platform, or location.

At present, almost circuits are wired using copper in flexible circuits. But, these circuit have limit to flexibility so it occurs fracture about cyclic bending and, thermal load of bending stress occur a circuit trouble. a study of all-polymer flexible circuits get over that problem. Established fabrication method of all-polymer circuits is photolithograph. This method can not have mass production, so this method wastes time and human effort. In this study, all polymer flexible circuits are fabricated using the inkjet process.

A complex-shaped part was successfully fabricated by Laminate Object Manufacturing (LOM) technique using silicon nitride tape with aligned silicon nitride whisker seeds. The ceramic tape was cut using a commercial cutting plotter according to the cross section drafts generated by slicing a 3-D model, and then the tapes were stacked sequentially. In order to improve adhesion between the tapes, stacking was performed under vacuum. After binder burnout, the part was encapsulated using latex emulsion and was cold isostaically pressed under 250 ㎫. It was sintered to 98.5% TD at 2148 K for 4 h under 2 ㎫ nitrogen pressure.

In this study, we have developed the stereolithography system that supports the development of a products. This paper presents the development of the stereolithography system. The system is composed of hardware, software and control part. The software converts a STL file to NC data and displays the monitoring figure in control part. The hardware part deals with structure of machine. The most important theme in this paper is LG-SLCAM software. This software can generate NC data and scanning condition data from a STL file semiautimatically. On the basis of three diensional shapes, it makes data for support structure from STL file. The effectiveness of using out stereolithography system is confirmed by processes of good development.
