Title: Distribution reduction gear for tandem mill
Inventor: SUZUKI SHIGENOBU
IPC: B21B35/02
Filed: 1990-05-02
Abstract: PURPOSE:To simplify a structure by arranging an intermediate pinion engaging with roll driving gears between the roll driving gears set to roll driving shafts of adjacent rolling stands and connecting an intermediate shaft providing this intermediate pinion with the above input shaft through a pair of bevel gears. CONSTITUTION:When the input shaft 10 is rotated and driven by a driving device, the intermediate shaft 13 is rotated through a pair of bevel gears 11, 12 and a roll driving gear 15 at an adjacent rolling stand is rotated and driven by one intermediate shaft 13. The reduction ratio is determined by the number of teeth of the bevel gears 11, 12, the intermediate pinion 14 and the roll driving gear 15. Since the reduction ratio can be set to every adjacent rolling stand, the reduction ratio can be set easily. Further, since the roll driving gear 15 for the adjacent rolling stand is driven by one intermediate pinion, the structure can be simplified. Consequently, gears, bearings, etc., used normally can be used, a reduction gear excellent in maintainability can be obtained.

Title: Heat radiator of electric equipment
Inventor: EMOTO MINORU
IPC: H05K7/20
Filed: 1984-06-07
Abstract: PURPOSE:To reduce the amount of the transfer of heat, which is yielded from a semiconductor, into the inside of a case, by using a configuration memory alloy for heat radiating plates. CONSTITUTION:Heat radiating plates 8 and 9 comprise a configuration memory alloy. When equipment is operated, heat is yielded from a semiconductor 3. The heat is transferred to the heat radiating plates 8 and 9. When the temperature of the heat of a contact point 12 exceeds a specified temperature alpha, the configuration of the heat radiating plate 9 is changed in the direction separating from a wall surface 2a of a case 2 together with the heat radiating plate 8. At this time, the heat is not directly transferred to the case 2 owing to the change in configuration of the heat radiating plates 8 and 9. The heat is emitted into air. Thus the temperature increase in the inside of the case 2 is prevented, and an electric part 7 and the like are protected from the heat.
