摘要： PURPOSE:To reduce the driving of a hydraulic pump and to save the energy in the apparatus by utilizing a large potential energy in the descending process of a beam in a hydraulic riving type walking beam device in a heating furnace for steel slab. CONSTITUTION:At the time of executing the heat treatment while carrying the steel slab, etc., in the heating furnace by lifting movement and advancing/ retreating movement of the walking beam device, the potential energy possessed in the descending process while laying heavy wt. of the steel slab on the shifting beam is accumulated in an accumulator as a pressurized working oil and this energy is utilized as the driving force at the time of ascending for laying the steel slab in the shifting beam. Further, the surplus energy at the time of moving the shifting beam to advance/retreat is accumulated in a second accumulator as a pressurized hydraulic working oil, and by utilizing this energy to a part of the driving force at the time of ascending the shifting beam for laying the steel slab, the capacity of the hydraulic pump for driving the walking beam is reduced. Further, the oil quantity returned back to an oil tank is reduced and the capacity of an oil cooler can be reduced.

摘要： PURPOSE:To facilitate a change of passage width by a method wherein a regulating member to regulate a passage width of a feeding passage for a disk-shaped body such as a playing medal is provided in such a manner that its mounting position can be changed freely, and a mounting position of a regulating member is guided by a guide mechanism. CONSTITUTION:A medal feeding device pushes a medal M transferred in an engagement with a rotary disk which is rotated at a reduced speed by a motor into a feeding passage 1 and feeds it along the feeding passage 1 out of a hopper. At this time, the medal M is fed outward in the rotation radious direction in a contact with a feeding member 3 at a periphery of the medal M and a passage width of the medal M fed out along the feeding member 3 is regulated by a cooperation of the feeding member 3 and a regulating member 4. In this instance, the regulating member 4 is provided with a swinging arm 27 which can swing around a shaft 29, and a mounting position of this regulating member 4 is guided by a guide mechanism 38 which is designed to receive in a medal receiver 43 a guide body 37 of the same diameter as that of the medal M and sandwiches it in the diametral direction.

摘要： PURPOSE:To provide a paper winding shaft constituting part which is simple in structure and capable of constituting a paper winding shaft in accordance with the size of a paper tube. CONSTITUTION:A tubulous member 2 is connected to a flange type member 1 fit and fastened to a drive shaft 25, and a ring expansion member 3 is installed on the outer periphery of the tubulous member 2. An air passage to communicate through to the inside of the ring expansion member 3 from the outer edge surface of the flange type member 1 and the tubulous member 2 is provided.
