Filed: 1993-04-06
Abstract: PURPOSE:To roll a projecting steel sheet excellent in precision of projection height by moving a plate thickness meter in the direction of the sheet width and confirming the projection height plessigly from the sheet thickness of each of the projecting part and the base part of the steel sheet obtained. CONSTITUTION:The steel sheet 1 is rolled by flat rolls 2, 3 and a grooveed roll 4 to manufacture a projecting steel sheet 1. As the plate thickness meter 5 mounted on the back side of the roll 4 is traversed in the direction of the sheet width, the thickness of the steel sheet 1 is measured.

Filed: 1981-05-25
Abstract: PURPOSE:To revolve an intermediate ring always in a lower speed than the speed of a rotary shaft by arranging trains of blades which are opposed to the opposite surfaces to the rotary ring and the intermediate ring of the captioned seal and to a static ring and the intermediate ring, and allowing the transmitted torque of the train of blades in each pair to be balanced. CONSTITUTION:A rotary ring 2 revolves in parallel with a rotary shaft 1, and the liquid in the train 11 of blades installed on the rotary ring 2 is allowed to circulate as shown by the arrow by the pumping action. The liquid enters into the blade train 12 from the blade train 11 and applies a rotary torque to an intermediate ring 4. The liquid in the blade train 13 is allowed to circulate as shown by the arrow by the pumping action due to the revolution of the intermediate ring 4. As the blade train 14 installed on the static ring 5 is not revolved at this time, the repulsive torque contrary to the direction of revolution is applied onto the blade train 13. When the number of revolution n2 of the rotary shaft 1 is constant, the relation between the torque and the ratio of revolution, n1 of the intermediate ring 4 to the n2, namely n1/n2, is shown by n1/n2=0.5 at the point A at which the rotary torque and the repulsive torque are equal. Therefore, the intermediate ring 4 revolves in half revolution number of that of the rotary shaft.
