摘要： A method of and an apparatus for rolling a rod as a starting material and producing a wire of 5 mm or smaller diameter, the method and apparatus using a continuous rolling mill comprising a plurality of round-grooved four-roll stands arranged in tandem, wherein the grooved four-roll is displaced between adjacent rolling stands by 45 degrees relative to each other around the pass line and the center-to-center distance between adjacent rolling stands measured in the pass line direction is not greater than 50 times the diameter of the rod. The front end portion of the rod is fed at slow speed into the continuous rolling mill, the front end portion being guided by a front pipe to the center of the round groove, and the front end portion is wound on a coiler. After that, the rotation speed of the grooved rolls in each rolling stand is so set as to prevent slack in the rod passing through the continuous rolling mill, and the rod is rolled at high speed, without causing the rod to touch the leading pipe, to produce a wire. Each of the rolling stands that constitute the continuous rolling mill is movable in a direction perpendicular to the pass line, each rolling stand being moved for connection to or disconnection from the driving source.

摘要： The present invention provides a mechanical pipe-end expander comprising a cone and a die having tapered wedge bodies whose outer radius is larger towards a flangeless end direction from a flange end, wherein a pipe-end zone is expanded by a wedge effect of the die, which results from a procedure that the cone and the die are inserted together into the pipe-end zone to be expanded, and that then only the cone is axially drawn outwards leaving the die within the pipe-end zone. A seamless steel pipe with an expanded pipe-end zone is manufactured by applying a mechanical pipe-end expander comprising a die having tapered wedge bodies whose outer radius is larger towards a flangeless end direction from a flange end. The resulting seamless steel pipe has satisfactory pipe-end dimensional accuracy, and exhibits characteristics with excellent field welding workability.

摘要： The inventive clothes dryer is provided with a system for preventing the overheating of the clothes in the drum caused by the abnormality in the V-belt, such as the break or derailment thereof. By the system, the power supply to the motor is halted temporarily while the motor is rotated at a predetermined speed, whereafter the motor keeps rotating due to its inertia. During the inertial rotation of a predetermined period of time, the number of rotations of the motor is counted. When the V-belt is in the normal state, the motor is loaded appropriately, so that the speed of the motor falls rapidly during the inertial rotation, and the number of rotations is accordingly small. When, on the other hand, the V-belt is in an abnormal state, the number of rotations is large. Therefore, the state of the V-belt is checked by comparing the number of rotations to a predetermined value, and when the number is smaller than the predetermined value, the drying operation is stopped.
摘要翻译： 本发明的干衣机设置有防止由V型皮带异常引起的滚筒中的衣服过热的系统，例如其断裂或脱轨。 通过该系统，马达在电机以预定速度旋转时暂时停止向马达供电，此后马达由于其惯性而保持旋转。 在预定时间段的惯性旋转期间，计算电动机的转数。 当V形带处于正常状态时，电动机被适当地装载，使得在惯性旋转期间电动机的速度急剧下降，并且转数相应地较小。 另一方面，当V形带处于异常状态时，转数大。 因此，通过将转数相对于规定值进行比较来检查V带的状态，当数量小于预定值时，停止干燥操作。
