A Trial-made Disc Type Chemical Polishing Machine

Shooting Type Polishing Machine

a rahalt-chromium (Co-Cr) alloy using a centrifugal shooting type polishing machine. In tha present work, we examined the effects of the texture of polishing particle and polishing time on the surface roughness of Co-Cr alloy cast specimens. Nine differcnt textures of polishing par'ticle were investigated wiLh respect to core material and paTticle abrasiveness: three (lifferent elastic body cer...

A Novel Disc-Type Reluctance Motor

This paper explores the theory and potential of a family of reluctance motors as well as brief review of different types of reluctance motors, motivated by the increased demands for geometric versatility and ruggedness for electric motors. This paper presents a new and novel disc type reluctance motor that has been designed built, tested, and analyzed. The magnetic circuit-based analysis shows ...

Adaptable Five-Axis Polishing Machine Head

Introduction A growing demand on machining high precision aspherical and free-form optics derives from the continuous development of computer-assisted calculation and simulation methods and therefore improved possibilities of integrating numerous optical functions within one and the same lens or mirror. Applications include illustration as well as sophisticated illumination optics. State-of-the...

Machine-Made Puzzles and Hand-Made Puzzles

Originally puzzles were not for recreation, but serious questions you might be killed if you couldn’t solve them. But in modern times, puzzles had become a sort of recreation, decreasing the seriousness and religiousness gradually. Now, the ‘rule creators’ of puzzles began to attract notice. I, as a rule creator, published a book, Kyoto University Student, Higashida’s Puzzles. I’ll show several...
