IPC: B31F1/28
Filed: 1990-09-10
Abstract: PURPOSE:To make it possible to remarkably reduce high frequency sound due to shell resonance by a method wherein pressing rolls for suppressing the crosssectional deformation of shell vibration are provided at least at two positions on the outer periphery of a pressure roll and the pressing position of at least one of the pressing rolls is made shiftable. CONSTITUTION:On the outer peripheral part of a pressure roll 3, pressing rolls 11a, 11b and 11c, some part of or all the width of each of which comes into contact with the pressure roll, are provided respectively. The pressing rolls 11b and 11c have shiftable structures. By rotating a motor, gears 19b and 19c are rotated and sector gears 18b and 18c, which respectively engage with the gears 19b and 19c, are rotated about the axis center of the pressure rolls 3, resulting in independently rolling the pressing rolls 11b and 11c along the outer periphery of the pressure roll. 3. Or the positional shifting of the pressing rolls 11b and 11c on the outer periphery of the pressure roll 3 becomes possible. Since the positional shifting action of the pressing roll 11a is not necessary from the view point of the mode of shell deformation, its position is fixed. Various deformations of shell vibration, which develop in response to running speed, are controlled by the pressing rolls 11a, 11b and 11c.

Filed: 1988-09-24
Abstract: PURPOSE:To maintain the output property of a fluid pressure linearly by installing a ball valve body to slide with the inner wall surface of a valve chest in the axial direction, and to seat in the first valve seat and the second valve seat selectively, in the valve chest. CONSTITUTION:When a current is applied to a solenoid 12, a plunger 13 is driven in the direction to separate from a ball valve body 4 against a compression spring 16, and the valve body 4 is separated from the first valve seat 31 and seated in the second valve seat 32. As a result, an output port 7 is cut off from linking to an exhaust port 8, and linked to an input port 6. Consequently, by feeding a pressure fluid through the input port 6 or by exhausting it through the port 8, the pressure of the output fluid is increased in the former case and decreased in the latter case. And by duty-controlling the flowing current to the solenoid 12 at a specific frequency, the output fluid pressure of the output port 7 is controlled at a pressure proportional to the duty ratio by the ball valve body 4.
