Title: Differential gear device having differential control mechanism
Inventor: MUNECHIKA TORU
IPC: F16H48/30
Filed: 1986-09-26
Abstract: PURPOSE:To transmit a differential movement according to a rotational angle of a steering wheel to a drive wheel and to prevent an unnecessary differential movement caused by a road surface or the like, by assembling a controllable pinion effecting the same rotation as a differential pinion of a differential gear and a control gear meshing therewith. CONSTITUTION:A clockwise rotation of an input shaft 1 causes a drive gear 2 to rotate, which rotates a differential case 3 in an upward direction by the same rotation. If a control gear 8 effects the same rotation as the case 3 in the instance, a control pinion 7 and a differential pinion 5 do not rotate so that no difference in rotation is caused in side gears 4, 5. Next, when the control gear 8 is rotated at a speed higher than the case 3, the control pinion 7 causes a differential pinion 6 to rotate counterclockwise with a result that the side gear 5 rotates at a speed higher then the side gear 4. When the control gear 8 rotates at a speed slower than the case 3, the side gear 5 rotates at a speed slower than the side gear 4 in the same manner. With the arrangement, a difference in rotation of right and left drive wheels of an automobile is produced in proportion to an angle of a steering wheel, whereby a differential movement greater than a necessary movement is not produced.

Title: Control method for roll gap of rolling mill
Inventor: NAKAYAMA TADAO
IPC: B21B37/58
Filed: 1986-09-29
Abstract: PURPOSE:To prevent a rolled stock from being caught by a rolling mill by driving a motor-driven rolling reduction apparatus to correct a position of a hydraulic rolling reduction apparatus to a vicinity of a neutral point at the time when an wedge reaches a prescribed limited value. CONSTITUTION:A position signal of the wedge 7 detected by a wedge position detector 9 is inputted in a wedge position discriminator 11 and calculated, then outputted to a control circuit 6 for driving a motor. By this output signal, the motor-driven rolling reduction motor 5 is driven to change a proper value of a roll gap by ascending or descending an upper housing 2. In this way, as the position of the wedge is always limited within the prescribed range, so a sufficient margin is given for the traveling extent of the wedge, the rolled stock is prevented from being caught by the rolling mill even if an edge crack is generated.
