    • A spark and throttle control arrangement for an internal combustion engine for altering the spark advance angle in response to the position of the throttle valve. The mechanism includes a throttle control lever and a spark control lever that are pivotally supported about independent pivot axes and a cam and follower arrangement operative between them so as to effect more rapid pivotal movement of the spark control lever than that of the throttle control lever during a phase of the initial rotation of the throttle control lever. Embodiments are disclosed so that the spark advance curve may be tailored to that of the engine by providing different rates of advance during different degrees of throttle opening and/or including a dwell.
    • 一种用于内燃机的火花和节流控制装置,用于响应于节流阀的位置改变火花提前角。 该机构包括节流控制杆和火花控制杆,所述节气门控制杆和火花控制杆围绕独立的枢转轴线枢转地支撑,以及在它们之间操作的凸轮和从动装置,以便在火花控制杆的作用下能够实现比节流控制杆更快的枢转运动 节流控制杆的初始旋转的相位。 公开了实施例,使得可以通过在不同程度的节气门打开和/或包括停留期间提供不同的提前速率来将火花提前曲线调整为发动机的曲线。

    • The invention provides a voltage-dependent nonlinear resistor porcelain in the form of a ZnO system sintered body comprising zinc oxide as a major component and at least one of rare earth element oxides, cobalt oxide, chromium oxide, at least one of Group IIIb element oxides, at least one of Group Ia element oxides, 0.01 to 2 atom % calculated as Ca of calcium oxide, and 0.001 to 0.5 atom % calculated as Si of silicon oxide as subordinate components, the atomic ratio of calcium to silicon (Ca/Si) ranging from 0.2 to 20. With the atomic ratio of calcium to silicon (Ca/Si) set between 0.2 and 20, preferably between 2 and 6, the element has a significantly increased load life at high temperature and humidity. The element experiences less deterioration of the asymmetry of its volt-ampere characteristic between different directions of DC conduction. If magnesium oxide is added to the composition in an amount of 0.05 to 10 atom % calculated as Mg, the benefits are enhanced, with grain growth suppressed and leakage current minimized even on high temperature firing.
