We introduce a method of color-coded illumination that is simple and fast. The purpose of this study is the real-time shape measurement of three-dimensional object by using color-coded information. The object is illuminated by a prism color spectrum. A color spectrum of a white-light source is imaged onto the object by illumination from one certain direction. The object is observed by a color CCD camera from a direction of observation, which is different from the direction of illumination. It can be evaluated by the red, blue, green using a inherence colors of hue value are good point.

The study was experimentally performed to investigated waste water freezing behavior in circular tube. The experiments were carried out for a variety of parameter, such as air-bubble flow rate, and cooled-plate temperature. It was found that the experimental parameters gave a great influence on the freezing rate and a heavy metal concentration of the waste-water.

Eeplosion fan is abbreviation for inert gas generator high temperature in cargo tank it desulfurize, exhaust and froze the gas that combined brimstone element and soot, then supply inert gas by blower and mack tank inside incombustible range this is equipment that nip in the bud the explosion. The blower for suppling inactivated gas has big impeller with heavy weight to achieve the high pressure, it causes a delay for first operation time and too much load is delivered to motor, total destruction by fire of motor is happen frequently. On this research, we will reduce the size and weight of impeller and install it with several stage, it makes an effect for reducing the first operation time. We also intend to contribute to efficient I.G.G. blower design by research a flow rate and pressure specialty from the diameter of impeller number of blades and size of casing.
