摘要： A shaft furnace for melting solid copper into molten copper has so far been controlled by manual operation with reference to the actual storage quantity of the building furnace. The burner air pressure of each zone of the shaft furnace is controlled by the actual storage quantity and the time change of it using Fuzzy Logic. The temperature of the molten copper is adopted as another input signal. The proportion of burner air pressure of the zones is revised by the temperature of the molten copper. Automatic control based upon the present invention decreases the fluctuation of the storage quantity of the holding furnace.

摘要： PURPOSE:To provide a tape winding-up device capable of spirally winding a thin tape at a high speed while keeping stable tension around a traveling wire. CONSTITUTION:Air blowing-out holes 3 are respectively formed on a shaft portion 1a and flange 1b of a reel shaft 1 to be rotated at a speed according to a tape winding diameter by means of a motor 7. Air makes a tape reel 31 float and bears it so as to have a predetermined rotating resistance. An inverted funnel-shaped flier 10. which is rotated at a constant speed by means of another motor 13, is coaxially disposed in the upper portion of the reel shaft 1. A tape 32 inserted into a guide hole 16 formed on the lower portion of the flier 10 travels under a tape cover 17 stuck to the outer surface of the flier 10, and the tape 32 is introduced around a wire rod 21 moving at a constant speed, via a tape winding-up guide 18 and a tape presser, which are rotated together with the flier 10. Accordingly, it is possible to reduce fluctuation of tape tension due to centrifugal force or an adverse effect of wind. Furthermore, an increase or decrease in rotating speed of the tape reel 31 on the reel shaft 1 by the fluctuation of tension can automatically correct an excess or shortage of a tape delivering quantity inevitably caused by rotation control of the motor 7. Consequently, the tension of the tape can become stable all the time, and winding at a high speed can be realized at a constant pitch.

摘要： PURPOSE:To produce the connector having the good connecting performance of optical cables at a low cost by forming a base body and a pressing body of the sintered bodies of silicon nitride ceramics. CONSTITUTION:This connector for the multiple fibers of the optical cables connects the cables by placing the optical fibers a exposed at the connecting end of the optical cable along V-grooves 11 of the base body, pressing and fixing the optical fibers a by the pressing body 20 superposed on the base body 10 and butting the end faces coaxially to the optical fibers in the connector of the other side. The base body 10 and the pressing body 20 are formed of the sintered bodies of the silicon nitride ceramics. This base body 10 and the pressing body 20 are adhered and a resin is embedded into the spacing therebetween. Then, the connector which has the high accuracy of the outside shape and has a smaller degree of deformation by a change in temp. and humidity is obtd. and, therefore, the misalignment of the optical axes between the optical fibers is substantially prevented. Further, the non-rusting property inherent to black zirconia is expected and the generation of cracking and chipping at the time of polishing the butt surfaces is obviated.

摘要： PURPOSE:To prevent generation of troubles such as roll breakdown by joining a metal plate on the side of a roll body made of ceramics and engaging a projection of a cross key with a key hole bored in the metal sheet. CONSTITUTION:A taper sleeve 16 is put on the tapered part of a driving shaft 15 and a roll body 17 made of ceramics is mounted on the sleeve 16. A metal plate 21 is joined on the side of the body 17 through a joining layer 22 and a couple of key holes 23 are formed. Projections 25 of a cross key 24 inserted into a lateral hole of the sleeve 16 and the shaft 15 are engaged with the key holes 23 to connect the shaft 15 with the body 17. By that, a stress concentration source such as a key hole, etc., is eliminated from the body 17 made of ceramics, so that troubles such as breakdown is prevented and working is also easily performable.
