20190234457 | BEARING ELEMENT - A bearing element has at least one inner ring element and at least one outer ring element, wherein, between the inner ring element and the outer ring element, a sliding bearing system is disposed that is formed by at least two sliding bearings. The sliding bearings have a sliding face, which cooperates with a running face of the opposite ring element. In the new condition of the sliding bearing, the sliding face of the sliding bearing, viewed in cross section, has at least one first sub-portion and one second sub-portion, wherein a tangent constructed on the first sub-portion is disposed at a first angle relative to the central longitudinal axis and a tangent constructed on the second sub-portion is disposed at a second angle relative to the central longitudinal axis, wherein the first angle has a magnitude different from that of the second angle. | 2019-08-01 |
20190234458 | BEARING DEVICE - In a bearing device, a squeeze film damper includes an annular oil chamber forming an oil film between an outer periphery of an outer race and an inner periphery of a bearing retaining member. A film thickness adjustment portion adjusting a film thickness of the oil film is provided in at least one location in a peripheral direction of the oil chamber. Therefore, it is possible, by changing a distribution in a peripheral direction of dynamic characteristics of the oil film of the squeeze film damper with a simple structure to thus freely adjust a forward mode tendency or a backward mode tendency for centrifugal whirling, to enhance damping performance of the squeeze film damper. Accordingly, centrifugal whirling of a rotating shaft is suppressed effectively by the squeeze film damper with a simple structure. | 2019-08-01 |
20190234459 | BEARING DEVICE - In a bearing device, a squeeze film damper includes an annular mass member disposed in a floating state between an outer periphery of an outer race and an inner periphery of a bearing retaining member, a first squeeze film damper part formed between the outer periphery of the outer race and an inner periphery of the annular mass member, and a second squeeze film damper part formed between an outer periphery of the annular mass member and the inner periphery of the bearing retaining member. Therefore, due to the floatingly supported annular mass member being eccentric with the opposite phase to a rotating shaft, which is eccentric and undergoes centrifugal whirling, an inertial force acting on the annular mass member counteracts the centrifugal force acting on the rotating shaft, thus enabling a damping effect to be exhibited. | 2019-08-01 |

20190234462 | CHABOT TRUE-AXIS BEARING - The Chabot True-Axis Bearing makes use of a naturally occurring circle. The heart of the invention is that this naturally occurring circle results from the path of least resistance given by the constant formation of malleable races. The dynamic nature of the bearing races produces a level of precision that fully exploits the grade of precision that is in the ball bearings. If the diameters of the ball bearings are within 0.000010 inches of one another, the concentricity of rotation of the host device will be within 0.000010 inches. This level of accuracy of concentric rotation is maintained throughout the life of the host device. | 2019-08-01 |

Namely, the current tripod stand is too weak to support such a heavy object. In addition, since the current tripod stand has only one extended rod, it cannot make its height longer than a sixpod stand. Especially the tripod is impossible to be used as a supporter for a photo studio background which need both strength and height. | 2019-08-01 |
