Filed: 1985-04-24
Abstract: PURPOSE:To obtain a diaphragm for speaker having a low density, a high rigidity, and a high internal loss by using the mixture of bleached sulfate pulp and flax pulp as main materials for paper making. CONSTITUTION:The mixture obtained by mixing bleached sulfate pulp and flax pulp is used as main materials to form the oscillating body by paper mak ing. For example, flax to which a digesting solution where the liquid ratio of 20% Na2SO3 solution to 4% NaOH solution is 1:7 is added is digested at 160 deg.C for 4hr, and the digesting solution is washed away completely after diges tion to obtain flax pulp, and this flax pulp is beaten by a beater to adjust the degree of beating to 75 deg.SR. Bleached sulfate pulp swollen for about 10min is supplied to the beater to adjust the degree of beating to 45 deg.SR with about 4.0% pulp concentration. They are adjusted to a pulp liquid of about 0.3% paper making concentration and are made into a sheet of a diaphragm by a paper making net tool which is formed into a cone and has 10cm diameter. This diaphragm is heated and pressured at 180-200 deg.C mold temperature with a prescribed mold and is dried.

Abstract: PURPOSE: To reduce the vol. in a detecting range and to facilitate the decision of cleanliness of a steel by acceleratedly rotating a cylindrical mold until molten steel therein forms as the cylindrical state and cooling and solidifying the molten steel while separating non-metallic inclusion from the molten steel. CONSTITUTION: The molten steel is poured into the cylindrical mold 1 and an air discharging hole 9 is opened and an inert gas cylinder 12 is connected with a gas supplying hole 10 to displace the air in the cylindrical mold 1 into Ar gas. The cylindrical mold 1 is rotated with a motor 7 and accelerated until the molten steel forms as the cylindrical state while giving the centrifugal force. The molten steel is heat-radiated and cooled to form solidified shell and further, the solidification is progressed toward the inner part. The non-metallic inclusions mingled in the molten steel and having small density are separated from the molten steel and solidified while shifting and accumulating as layer- state in the inner part to make the cylindrical sample.  Since the inclusions in this sample are accumulated in the inner part and the vol. of the detecting range can be reduced, the cleanliness of the steel can easily be decided.
