    摘要: A method of controlling the operation of a cross helical rolling mill. The cross helical rolling mill has a pair of work rolls arranged at respective predetermined lead angles, and a pair of power-driven drive roller shoes arranged obliquely at predetermined lead angles on both sides of the rolling region formed between both work rolls. The method comprises controlling the rotation speed of each of the drive roller shoes in synchronism with the speed of rotation of the rolled material such that the difference in the peripheral speed between each of the drive roller shoe and the rolled material falls within a predetermined range, and, simultaneously with the control of the speed, controlling the driving torque applied to each of the drive roller shoes. According to the method, the drive roller shoes impart driving torques to the rolled material, while maintaining the slip between the shoes and the rolled material within a predetermined allowable range, so that the material under the rolling can be held safely and stably, whereby the quality of the rolled product is improved and the lift of the shoes is prolonged. Disclosed also is an apparatus for carrying out this method.

    摘要: To provide a fastening structure for fastening a left-right screw intersection forming bolt, which has a simple structure and does not loosen. A right screw nut having a recess, an elastic member having a rotation-preventing protrusion and a tongue portion, and a left screw nut having a tapered surface and a recess are included. After the bolt is tightened with the right screw nut and the elastic member is mounted, the tongue portion of the elastic member is tightened while being pressed with the left screw nut, so that the tongue portion jumps up to the recess of the left screw nut, and the left screw nut is locked and fastened. As illustrated in FIG. 9, the fastening structure can also be configured by changing the right screw nut to a left screw nut, the elastic member to an elastic member, and the left screw nut to a right screw nut.

    摘要: Disclosed is a stamping device for use in facsimile equipment, wherein a document has a mark stamped hereon after its information has been transmitted. The stamp device is composed of a stamp body which has a stamp face for marking the document and a handling knob; a mounting plate for detachably holding the stamp body; and a solenoid for moving the mounting plate, whereby the stamp face is pressed onto the document so as to stamp the mark. The stamp body and the mounting plate are shaped so that the stamp body is engaged with a freely removed from the mounting plate by using the knob of the stamp body.
