摘要： PURPOSE:To aim at improvement in parallelism and flatness, by applying a first polishing to both sides side by side of the sheet stuck to a work holder via wax, correcting each surface roughness and, after stress release by means of heating and annealing, applying a second polishing likewise. CONSTITUTION:A workpiece 1 of a germanium sheet or the like is stuck to a work holder 2 via wax 3, while a first polishing by diamond abrasive grains is applied to a polishing surface A, and surface from and surface roughness are corrected. Next, the surface A is turned down, and surface form and surface roughness of a polishing surface B are corrected likewise. Afterward, it is heated up to a temperature, for example, of 60-80 deg.C where the wax 3 is melted, annealed, stress is released, and the workpiece 1 is clamped in a curved state by a polishing strain difference, applying a second polishing to the A surface as well, then it is turned down, thus this second polishing is applied to the B surface as well, and both surfaces A and B are formed into a polished surface being high in from accuracy. Thus, parallelism and flatness is both surfaces of the sheet are polishable so favorably and, what is more, such a surface that is high in form accuracy is securable.

摘要： PURPOSE:To easily reduce the noise of an oil-immersed electrical apparatus which is transmitted through the oil within the joint pipe connecting said oil- immerced electrical apparatus and a cooling device by providing a noise absorbing material at the inside of a bent portion prepared in said joint pipe. CONSTITUTION:Noise generated by the transformer 1 and is transmitted by the oil 3 in the joint pipe 6 is absorbed by the absorbing material 7 provided in the bending portion 2a. In this case, since the noise absorbing material is provided at least the area to which sound wave of noise generated from the unit 1 collide at the inside of the bending portion 6a of joint pipe 6, the noise which is passing in the joint pipe 6 is effectively absorbed by such absorbing material. If the noise which passes within the joint pipe 6 from the pipe wall 6b of joint pipe 7 and leaks to outside of the chamber 2a is as high as being judged as a problem, such noise can also be reduced by providing as required the noise absorbing material at the outside of pipe wall 6b.
