    • A wheel bearing device is proposed which maintains long life even under high-load, high-temperature conditions. On the surfaces of inner rings and tapered rollers of a multiple-row tapered roller bearing rotatably supporting a wheel, carburized, nitrided layers are formed which contain 0.80 wt % or more carbon and have a Rockwell hardness of 58 or over with the residual aaustenite content being 25-35 vol % to improve mechanical properties and fatigue characteristics of these parts and also keep the surface layers of these parts of suitable toughness, thereby improving the life of the wheel bearing device in a high-load, high-temperature environment. Also, an annular recess is formed in the inner periphery of the outer ring at a portion between the rows of the raceways.
    • 提出一种车轮轴承装置,即使在高负荷,高温条件下也能保持长寿命。 在可旋转地支撑车轮的多列圆锥滚子轴承的内圈和圆锥滚子的表面上,形成含有0.80重量%或更多的碳并且具有58或更高的洛氏硬度的渗碳氮化层,并且残余的奥斯汀含量 25-35vol%,以改善这些部件的机械性能和疲劳特性,并且保持这些部件的表面层具有合适的韧性,从而在高负荷,高温环境下提高车轮轴承装置的使用寿命。 此外,在外圈的内周中在滚道的行之间的部分处形成环形凹部。

    • A clock shaping device includes a first clock signal selection portion that selects between a reception clock signal and a back-up clock signal based on a detected loss in the reception clock signal. A second clock signal selection portion selects between a clock signal received from the first clock signal selection portion and a clock signal received from a quartz crystal oscillation circuit based on a detected loss in the back-up clock signal. A voltage controlled oscillation circuit has a frequency that varies with a control voltage being supplied and outputs a feedback loop output signal. A phase comparison portion generates a phase difference signal based on a comparison between the feedback loop output signal and a clock signal outputted from the second clock signal selection portion. A loop filter smoothes the phase difference signal and outputs the phase difference signal in the form of the control voltage.
    • 时钟整形装置包括:第一时钟信号选择部分,其基于接收时钟信号中的检测到的损耗在接收时钟信号和备用时钟信号之间进行选择。 第二时钟信号选择部分基于在备用时钟信号中的检测到的损耗,在从第一时钟信号选择部分接收的时钟信号和从石英晶体振荡电路接收的时钟信号之间进行选择。 电压控制振荡电路具有随提供的控制电压而变化的频率并输出反馈回路输出信号。 相位比较部分基于反馈回路输出信号与从第二时钟信号选择部分输出的时钟信号之间的比较产生相位差信号。 环路滤波器平滑相位差信号,并以控制电压的形式输出相位差信号。

    • A sealing device designed to minimize accumulation of a fluid medium trapped therein to thereby increase a sealing performance and adapted to seal a space between inner and outer peripheral members rotatable relative to each other. The sealing device includes a generally L-sectioned annular sealing plate fitted to one of the inner and outer peripheral members and a generally L-sectioned annular sealing element fitted to the other of the inner and outer peripheral members so as to confront the sealing plate. The sealing plate has a radial wall and a tilted wall extending from the radial wall so as to incline inwardly thereof, and the sealing element includes a generally L-sectioned base plate provided with an elastic member. The elastic member has a side lip slidably engageable with the radial wall of the sealing plate and a radial lip slidingly engageable with a cylindrical sleeve of the sealing plate.
    • 一种密封装置,其设计成使被捕获的流体介质的积聚最小化,从而增加密封性能并且适于密封可相对于彼此旋转的内外周构件之间的空间。 该密封装置包括一个大体为L形的环形密封板,该密封板安装在内外周件之一和大体上L形的环形密封元件,该密封件安装在内周和外周件中的另一个上,以便面对密封板。 密封板具有径向壁和从径向壁延伸以向内倾斜的倾斜壁,并且密封元件包括设置有弹性构件的大致L形截面的底板。 弹性构件具有可与密封板的径向壁可滑动地接合的侧唇和与密封板的圆柱形套筒滑动接合的径向唇缘。
