Aspects and/or features of the product We offer a versatile protractor having four functions for drawing figures, which can provide an unlimited possibilities, and a power generating unit, which can prevent energy crisis, including disposal of nuclear waste, destruction of the ozone layer and global warming to conserve the future of our planet.
Information of the main materials, costs and filed of use
Products or parts name Elite Quartet (with versatile functions for drawing figures)
Products or parts description A writing material having four functions of compass, triangle rulers, protractor and scale.
Features When you measure the length between two points, you can obtain the measurement immediately by fixing one point with the pin and judging which small hole coincides with the other point.
Field of use For arithmetic and drawing and manual arts for elementary school students, drafting for designers, recreational drawing, and finger movement training for seniors.
Products or parts name Rotating equipment and rotating force discharge equipment
Products or parts description A unit generating electricity by taking water, which is a rich resource circulating in nature, into a water tank and converting the bottom pressure to rotating force.
Features This product allows flexible designing from large to small scales according to the quantity of water and can be used wherever water exists throughout the world, whether it is in a mountain area or a remote island. This product provides environmentally friendly, clean energy without emitting any waste harmful to humans.
Field of use
Products or parts name Construction problems "Solve by Compass and Straightedge Construction"
Products or parts description In this book, constructibility conditions for the three problems are sought out by using applied Pythagorean theorems, circle equations and special circle natures, and all laws regarding graphical solutions for special circles are re-confirmed to analyze approximate construction of the three problems. This book includes explanation of a new discovery in construction: basic construction methods for regular polygons (triangle, pentagon, heptagon, nonagon and heptadecagon); and construction problems.
Features Three difficult problems that have been set by ancient Greeks to future generations: (1) Doubling the cube, (2) Angle trisection, and (3) Squaring the circle are analyzed.
