Patent number: 10974251Abstract: A pulverizing device includes: a housing; a pulverization table configured to rotate inside the housing; and a throat, disposed inside the housing on a radially outer side of the pulverization table, for forming an upward air flow. The throat includes: an inner ring extending along an outer periphery of the pulverization table; an outer ring, disposed on a radially outer side of the inner ring so as to form an annular flow passage between the inner ring and the outer ring; and a plurality of throat vanes disposed between the inner ring and the outer ring. The following expressions are satisfied: 2.0?L/d?4.0; and 0.5?H/d?1.5, where H is a gap between the inner ring and the outer ring with respect to a radial direction, L is a length of the throat vanes, and ādā is a distance between adjacent two of the throat vanes.Type: GrantFiled: January 13, 2017Date of Patent: April 13, 2021Assignee: MITSUBISHI POWER, LTD.Inventors: Jun Kashima, Shinji Matsumoto, Kosuke Kitakaze, Yasuhito Onishi, Hiroaki Kanemoto

Patent number: 6170682Abstract: The car under-frame of the invention comprises a planar coupling member 2 projecting from a first car C toward a second car B, a bearing inner ring 3 positioned on the upper side of planar coupling member 2 and secured rigidly thereto, a bearing outer ring 6 disposed on the outer peripheral side of bearing inner ring 3 through balls, a bearing step 5 positioned on the upper side of bearing outer ring 6 and to which the bearing outer ring is rigidly secured, and an articular coupling member 7 projecting from the second car B toward the first car C to grip a mounting arm 5b of bearing step 5. The mounting arm 5b of bearing step 5 is integral with a generally discoid body segment 5a and disposed below the top end face of body segment 5a and extending radially outwardly from either side of body segment 5a. In accordance with the invention there can be provided a under-frame structure which makes it possible to lower the car floor level without interfering with strength and coupler performance.Type: GrantFiled: November 17, 1998Date of Patent: January 9, 2001Assignee: The Rinki Sharyo Co.
