摘要： A wheel bearing assembly is provided which has a rotating speed sensor unit which includes a seal for preventing entry of foreign matter and which takes up little space and thus can be mounted on the wheel bearing assembly without increasing the axial dimension of the fixed member of the wheel bearing assembly. The assembly includes a fixed member fixed to a vehicle body, and a rotary member rotatably supported in the stationary member through a bearing and mounted to a vehicle wheel. An annular sensor is fitted to a knuckle, which is a part of the fixed member, on the inboard side of the bearing. A sensor seal is fitted to the annular sensor and has a seal lip kept in slide contact with a seal land formed on a constant-velocity joint outer ring, which is a part of the rotary member, to define a sealed space on the inboard side of the bearing. An encoder is mounted on a bearing inner ring, which is a part of the rotary member, in the sealed space. The sensor element is disposed in the sealed space, opposite the encoder.

摘要： An annular support ring 32 is fitted onto the outer periphery of each trunnion 22. This support ring 32 and the roller 34 are unitized via a plurality of needle rollers 36 to constitute a roller assembly capable of relative rotations therebetween. In longitudinal section, each trunnion 22 has an outer periphery of straight shape, parallel to the axis of the trunnion 22. In cross section, the trunnion 22 has a generally ellipse shape with the major axis orthogonal to the axis of the joint. The inner periphery of each support ring 32 is arcuate and convex in section. This combines with the general elliptic cross sections of the trunnions 22 and the provision of predetermined clearances between the trunnions 22 and the support rings 32, to allow the support rings 32 to move along the axial directions of the trunnions 22 as well as make tilting movements with respect to the trunnions 22.

摘要： [Summary][Object] It is an object of the present invention to provide a portable information terminal device and a display device capable of effectively suppressing a display screen from being peeped from an oblique direction.[Means for Settlement] A first pattern area and a second pattern area are formed in a display area of a display device 5; in a wide viewing field mode, the whole of the display area is brought into a wide viewing angle state; and in a narrow viewing field mode, a first divided state in which the display area except the first pattern area is brought into a narrow viewing angle state, and a second divided state in which the display area except the second pattern area is brought into the narrow viewing angle state are dynamically switched. For this reason, if the display area in the narrow viewing field mode is peeped from the oblique direction, a high contrast moving pattern arising from the difference in viewing angle is viewed, and thereby the conscious of the peeper can be attracted to the pattern. Accordingly, even if a screen display is visible with a low contrast, it can be prevented from being easily made out.
摘要翻译：发明内容本发明的目的是提供一种能够有效地抑制显示屏从倾斜方向窥视的便携式信息终端装置和显示装置。 [结算手段]在显示装置5的显示区域中形成第一图案区域和第二图案区域; 在宽视野模式下，整个显示区域进入宽视角状态; 并且在窄视场模式中，将第一图案区域之外的显示区域变为窄视角状态的第一分割状态和将第二图案区域除外的显示区域进入第二分割状态动态切换窄视角状态。因此，如果从倾斜方向窥视窄视场模式的显示区域，则可以观察到由视野差异引起的高对比度运动图案，从而可以将窥视者的意识吸引到图案上。因此，即使以低对比度可见的屏幕显示，也可以防止容易地形成。
