Abstract: PURPOSE:To decrease bending strain by dispersing and incorporating a water absorptive swellable material of powder having <=50mum grain size as a water absorptive swellable component into a water absorptive swellable material layer. CONSTITUTION:This tape is formed by dispersing and incorporating the powder of the water absorptive swellable material having <=50mum grain size into the water absorptive swellable material layer. Since the coefft. of friction of the surface is decreased by the powder, optical fiber cores 8 move freely when bending is applied to the optical fiber itself even in such structure in which the optical fiber cores 8 and the water stopping tapes 7 are juxtaposed. The elongation strain based on the suppression of the movement of the optical fiber cores 8 is thereby no longer generated and the resultant cable has a good waterproof characteristic and the decreased bending strain.

Abstract: PURPOSE:To reduce the time required for sampling and analysis operations at the blowing-out and improve converter operating efficiency by estimating the molten steel components at the blowing-out from the sample drawn during oxygen blowing with high accuracy at the time of refining steel in a converter. CONSTITUTION:From the relation that the [C] and content [M] of one kind of Mn, P and S in the molten metal at the end period of oxygen blowing by a converter progress by maintaining the specified relation, the formula I indicating the relation between the [M] and [C] in the steel bath is obtained. At the same time, the formula II which determines the constant beta at every heat in the formula I is obtained. First, the estimated beta value is obtained from the results of the analysis of the molten steel sample drawn during blowing and this value and the [C] by the above-mentioned sample analysis are substituted into the formula I to calculate the estimated alpha value of this heat. Next, the [C] obtained from the freezing temperture and spark decision of the molten steel sample at the blowing-out is substituted together with alpha and beta into the formula I to estimate the value of the [M] of the steel bath at the blowing-out. From this value, the stoppage or continuation of the oxygen blowing is determined, whereby the time for the blowing-out is decided.

The TR 1 is applied at its gate with a clock signal theta which drives the drivers D1 and D2, so it operates in synchronism with those drivers D1 and D2. Therefore, a clock depending upon the high voltage output from the capacitor C is further raised in level depending upon the positive side power source level Vcc and sent out to the output terminal OT of the driver D2.
