Filed: 1989-10-12
Abstract: PURPOSE:To omit a stage for compounding a binder and to simplify the process by adding the stock soln. of water glass as a binder and ice grains for dilution to a compounded flux for the coating material for welding rods and kneading the mixture. CONSTITUTION:The coating material for welding rods can be obtd, by one effort by charging the compounded flux (a), the stock soln. (b) of the water glass and the ice grains (d) in the kneading stage B at the time of kneading the compounded flux. While the compounded flux (a), the stock soln. (b) of the water glass and the ice grains (d) may be simultaneously charged and stirred at this time, these materials are so kneaded as to maintain the granular state without allowing the ice grains to completely melt at least before the materials are uniformized. The uniform mixing effect inherent in the ice grains is, therefore, effectively utilized if the stock soln. (b) of the water glass is added to the compounded flux (a) and the mixture is kneaded after the ice grains (d) are charged thereto.

Filed: 1989-10-11
Abstract: PURPOSE:To improve a measuring accuracy by detecting the position in the width direction of the tape wound on a tape drawing post with the variation in the received light quantity of a light receiving sensor and keeping the distance between the sensor and post constant. CONSTITUTION:A back tension post 5 draws a tape 27 out of a cassette 1 so as to press the nonmagnetic face of the tape 7 by the revolving centering around the shaft 31 of a post support block 32. It is then moved until abutting to a stopper 30. When it is stopped in the state of its abutment on the stopper 30, the back tension post and tape 27 wound thereon are held in a constant distance to a sensor 21. A specific light is then radiated on the post 5 with the reference traveling position of the tape 27 as the center and the reflected light is detected on a photodetector 23. Due to the reflectivity differing with a specular finishing white post and black tape 27, the tape displacement is measured as the variation in the reflection light quantities of the post face.
