摘要： A plurality of sensing units are buried at suitable intervals in an area of ground or a snow accumulation section to be observed. Each of the sensing units includes a gyro-sensor for, when external force acts on it as a result of the displacement of the ground or the snow accumulation section, sensing impulsive acceleration from the magnitude and direction of the displacement and the inclination of the sensing unit itself, and a transmission section for transmitting the sense data by radio. A base station acquires the sense data transferred from the sensing units, processes the sense data for each measuring point in real time, determines the movement of the ground and/or the snow accumulation section, and judges a state of the ground and/or the snow accumulation section on the basis of the movement.

摘要： A one-way clutch has a plurality of engagement members disposed between an inner ring and an outer ring and spaced at regular intervals in a circumferential direction of the one-way clutch, an annular retainer having a cylindrical part with pockets for receiving the engagement members and a flange which is continuous with an axial end of the cylindrical part and protrudes radially outwardly, and an annular spring for urging the engagement members in a direction of engagement with the inner and outer rings. The retainer has at least one pair of engagement portions to be engaged with the outer ring, the paired engagement portions being located substantially symmetrically relative to an axis of the retainer. Each engagement portion is defined between two pockets and between two slits respectively connected to the two pockets and passing through the flange to the outside of the retainer. The flange in each engagement portion has an outer radius larger than that of a portion of the flange other than the engagement portions and larger than a radius of an inner surface of the outer ring.

Grooves are respectively formed on opposite end portions of an outer peripheral surface of the projections of the outer ring at regular intervals in a circumferential direction. Each of the end bearing retainer plates is provided with fitting portions which are integrally formed around an outer periphery of the end bearing retainer plate at regular intervals and which are respectively engaged with the grooves of the outer ring. One of the end bearing retainer plates is also provided with spring portions which are integrally formed around the outer periphery and which axially project to rest against a part of the housing when placed in position in the housing.

摘要： A method for manufacturing a one-way clutch cage allows slits of the cage to be formed with a short punching distance, wherein the slits are narrow in width and the cage is less prone to deformation. In this method for manufacturing a one-way clutch cage, after slits 8, 10, 11, 12 have been formed, windows 17 are formed and then an outer annular part 18 is cut. Therefore, since the slits can be formed in a cylindrical member 2 that has not yet been subjected to the window formation process of the outer annular part cut-out process, and that is sufficiently strong, a radially diagonal punching operation can be performed to form the slits. During this radially diagonal punching operation, a boundary portion between a cylindrical portion 3 and an outer flange 5 is punched out from an inside of the cylindrical member toward an outside of the cylindrical member. Thus, the punching distance can be shortened, the punching die can be thinned in thickness and the slit width can be reduced, as compared with horizontal punching.

摘要翻译： 用于制造单向离合器保持架的方法允许保持架的狭缝形成短的冲压距离，其中狭缝的宽度窄，并且保持架不容易变形。 在该单向离合器保持器的制造方法中，在形成狭缝8,10,11,12之后，形成窗口17，然后切断外侧环状部18。 因此，由于狭缝可以形成在尚未经受外环形切断工序的窗口形成处理的圆筒构件2中并且足够坚固，因此可以进行径向对角冲孔操作以形成 狭缝。 在这种径向对角冲孔操作期间，圆柱形部分3和外凸缘5之间的边界部分从圆柱形部件的内部朝向圆柱形部件的外侧冲压。 因此，与水平冲压相比，可以缩短冲孔距离，可以减少冲孔模具的厚度，并且可以减小切口宽度。
