    • In an integrated circuit having an internal supply voltage generation circuit which generates an internal supply voltage by descending an external supply voltage, there is provided an internal circuit which operates with a supplied internal supply voltage. The internal supply voltage generation circuit changes an internal supply voltage level to be generated in accordance with an operation speed of the internal circuit. Preferably the semiconductor integrated circuit includes a clock control circuit which generates an internal clock signal the frequency of which is controlled in accordance with the operation speed of the internal circuit. When the internal clock signal is controlled to have a higher frequency, the internal supply voltage is controlled to be higher. Also, when the internal clock signal is controlled to have a lower frequency, the internal supply voltage is controlled to be lower.
    • 在具有通过降低外部电源电压而产生内部电源电压的内部电源电压产生电路的集成电路中,提供了以所提供的内部电源电压工作的内部电路。 内部电源电压产生电路根据内部电路的运行速度改变要产生的内部电源电压。 优选地,半导体集成电路包括时钟控制电路,其生成内部时钟信号,其频率根据内部电路的操作速度被控制。 内部时钟信号被控制为具有较高的频率时,内部电源电压被控制得更高。 此外,当内部时钟信号被控制为具有较低的频率时,内部电源电压被控制为较低。

    • To effectively restrict occurrence of radially extending grooves in tire sidewall portions, turn-up portions (N) of a tire structure member (K) are turned up around the beads (B) by synchronously moving turn-up arms (66) axially inward by a moving means (75), with turn-up rollers (70) maintained in contact with the turn-up portion (N), and simultaneously, by synchronously swinging the turn-up arms (66) radially outward by a swinging means (76). The contact pressure of the turn-up rollers (70) applied to the turn-up portion (N) can thus be easily adjusted to an optimum value, with the result that impressions (grooves) produced in the outer surface of the turn-up portion (N) (which becomes part of the tire sidewall portion after being turned up) can be kept as shallow as possible.
    • 为了有效地限制轮胎侧壁部分中的径向延伸槽的发生,轮胎结构构件(K)的翻转部分(N)通过沿轴向向内同步移动翻转臂(66)而绕着胎圈(B)而转动 移动装置(75),其具有与翻转部分(N)保持接触的翻转辊(70),并且同时通过摆动装置(76)径向向外摆动上翻臂(66) )。 因此,施加到折返部(N)的翻转辊(70)的接触压力可以容易地调节到最佳值,结果是在折叠的外表面中产生的印模(凹槽) (N)(成为轮胎胎侧部分后的轮胎部分)可以保持尽可能的浅。
