  • Patent number: 7469695
    Abstract: A method for manufacturing a single stone into a regular dodecahedral ornament or a regular icosahedral ornament, and the ornament manufactured according to the method are provided. The method enables the ornament to be manufactured at low costs with ease without using a complicated, numerically computer-controlled shaping machine. The geometric features determining the faces and ridges of a regular dodecahedron or a regular icosahedron are drawn as cutting base lines on each surface of a cubic workpiece. On a face formed by cutting based on the cutting base lines, new auxiliary cutting lines are sequentially drawn by marking. Then, based on these auxiliary cutting lines and the remaining cutting base lines, a possible cut face is determined, which is in turn cut using a cutting tool. The cutting base lines which are erased after each cutting are complemented by auxiliary cutting lines to find a new possible cut face, which is in turn cut in sequence, thereby manufacturing the regular polyhedral ornament.

  • Patent number: 7427227
    Abstract: In a fluid polishing method for processing a fine aperture by slurry 7, the slurry is supplied from a cylinder 2a in a slurry flow rate target process until the flow rate increases to a target value of a slurry feed flow rate. When the flow rate reaches the target flow-rate, the cylinder is stopped and switched to another cylinder 2b and the operation fluid flow rate of the fine aperture is thereafter measured. In a metering process, to be executed next, a necessary processing time is calculated on the basis of the operation fluid flow rate and polishing is carried out for a necessary processing time by another cylinder 2b. Another cylinder is then stopped and switched and the operation fluid flow rate is measured. In this way, the metering process is repeated until the operation fluid flow rate reaches a predetermined value. In each process, the supply of the slurry is not interrupted.
