摘要： PROBLEM TO BE SOLVED: To reduce size and weight by reducing a power required for switching from braking to non-braking excellent in magnetic efficiency. SOLUTION: The eddy current reduction gear is of "magnet pole surface counter type". It is provided with an attraction detecting means which detects an attractive force that occurs between a braking disc and a permanent magnet. The permanent magnet sets a first set value or a second set value according to a braking position. If a detected value by the attraction detecting means is equal to or higher than the set value, the permanent magnet shifts to a non-braking position or keeps the non-braking position. As a means for directly or indirectly detecting the attraction, a tachometer that measures the rotational number of the brake disc, a displacement gauge for measuring the amount of displacement of a support plate of the gear, a load cell provided to a piston rod, or vehicle speed sensor may be used.

摘要： PROBLEM TO BE SOLVED: To suppress the drag torque produced at braking off, without marring the braking force at braking on, as much as possible.
SOLUTION: This is a single row turn system of eddy current type reduction gear. A ferromagnetic plate 11, of quality difference from that of a switch plate 4, is arranged at the outside periphery or inside on outside periphery side of each support 5, so that it contacts with at least the switch plate 4 on the front end side in the rotational direction of the rotor 1, or the ferromagnetic plate 11 of quality different from that of the switch plate 4 is attached to the topside of the switch plate 4 on the front end side in the rotational direction of the rotor 1, being directed toward the switch plate 4 on the rear side in the rotational direction of the rotor 4 from the switch plate 4 on the front end side. Consequently, since this will not impair the braking force at braking-on as far as possible, this can suppress the magnetic flux generated from a permanent magnet, as matter of course, the magnetic flux leaking out to the cylinder of the rotor from switch plate decreases, accompanying the decrease of the magnetic flux generated from the permanent magnet at this braking-off, and this can suppress the drag torque.

摘要翻译：要解决的问题：为了抑制在制动时产生的阻力矩，尽可能不损坏制动时的制动力。解决方案：这是涡流式减速装置的单排转向系统。与开关板4的质量差异的铁磁板11配置在各支架5的外周侧的外周侧或内侧，使其至少与前端侧的开关板4接触转子1的旋转方向或质量不同于开关板4的铁磁板11的旋转方向在转子1的旋转方向的前端侧安装在开关板4的顶侧，朝向开关板4在前端侧从开关板4沿转子4的旋转方向在后侧。因此，由于这不会尽可能地削弱制动时的制动力，所以能够抑制从永久磁铁产生的磁通，当然磁通从开关板泄漏到转子的气缸伴随着在该制动时从永磁体产生的磁通量的减少，这可以抑制拖曳转矩。

摘要： PROBLEM TO BE SOLVED: To suppress drag torque generated during braking off without degradation of a braking force during braking on as much as possible. SOLUTION: This single-line revolving eddy current type reduction gear has a structure so that the entire external surface of a support material 5 having a box shape in cross section, or at least part of an area on a switch plate 4 out of the external surface of the support material 5 coming into contact with the rear end of a rotor 1 in the rotational direction of the rotor 1 is coated with a surface treated layer 11. It is possible to suppress a magnetic flux generated from a permanent magnet during braking off without degradation of the braking force during braking on, and reduce the magnetic flux naturally leaking from the switch plate to the cylindrical part of the rotor as the magnetic flux which is generated from the permanent magnet during braking off is reduced, thereby suppressing the drag torque.

摘要： PURPOSE:To restrain the surface temperature of a die from rising and to prolong the life of the die by specifying the time when the die and the slab come in contact with each other every time hot slab is rolled down in width. CONSTITUTION:A pair of width rolling down dies 2 arranged on both sides of a feed line of the hot slab 3 are moved forward and backward to roll down the hot slab 3 in width. In that case, the surface temperature of the die 2 rises and deformation, friction, etc., are generated on the surface. The rise of the surface temperature of the die restrained to prolong the life of the die 2. The surface temperature of the die depends highly upon the time when the slab 3 comes in contact with the die 2 and is hardly affected by the length of the non-contact time. Consequently, the time when the slab 3 and the die 2 come in contact with each other is reduced to
