摘要： PURPOSE:To improve the heat retaining properties, measuring accuracy of viscosity and operating economy of a heating furnace by fitting a plug having a loose fitting hole for a vibrating piece into an insertion port of a sample container of the heating furnace, and providing the loose fitting hole with a furnace lid. CONSTITUTION:A though-hole 22 is formed in an up-and-down direction of a main body 21 of an electric furnace. A core pipe 23 is fitted in the hole 22. Moreover, a plug 26 is detachably fitted in the hole 22. The plug 26 has a square hole 26a allowing a vibrating piece 3 to pass therethrough at the center in a diametrical direction from an upper opening of the pipe 23. The upper opening of the plug 26 is closed by a furnace lid 27 which is freely opened. Even when the lid 27 is closed, there are secured a loose fitting hole into which a vibrating rod 4 is loosely fitted, and an insertion hole for inserting a protecting pipe having a wire of a thermocouple inserted. Therefore, while the temperature of a melt 1 in a crucible 2 is measured, the radiation from the melt 1 can be shut off by the plug 26 and lid 27, with improving the heat retaining properties. As a result, the temperature distribution of the melt 1 can be maintained good, so that the measuring accuracy of viscosity is improved. In addition, the power consumption is saved.

摘要： PURPOSE:To execute the uniform mirror-like surface finishing even for a broad polished surface by detecting the elastic pressure of an elastic body for a polishing head by a load cell and feedback-controlling an elastic force adjusting means. CONSTITUTION:Since the pressing force of a polishing head 16 for carrying out the electrolytic buffing compounding polishing for a polished surface A is the sum of the elastic pressing force of an elastic body 31 due to the adjustment of a screwing member 30 and the weight sum of the polishing head 16 and a rotary shaft 11, adjustment can be easily carried out by the springy force of the elastic body 31. The elastic pressure of the elastic body 31 is detected by a load cell 28, and a calculation control circuit 32 outputs the control signal into an actuator 3 suspended onto a base 2 according to the detection signal, and raises and lowers a whole housing 1 and expands and contracts the elastic body 31 by varying the interval between the screwing member 30 and a receiving seat 27, and the automatic adjustment to a prescribed elastic pressure is permitted. Therefore, uniform mirror-like surface finishing can be carried out, even for a broad polished surface, and the mirror-like surface finishing with fine surface roughness for the polished surface is permitted.
