摘要： A compensation circuit (14) for a ring oscillator (12) having an odd plurality of series-connected CMOS inverter stages includes first and second P-channel transistors and a resistor. The first transistor (32) has a source coupled to VDD and a gate coupled to ground. The resistor (34) is coupled between the drain of the first transistor and ground. The second transistor (36) has a source coupled to VDD, a gate coupled to the drain of the first transistor, and a drain coupled to a supply node of each of the inverter stages of the ring oscillator for providing a supply voltage that is compensated with respect to voltage, temperature, and semiconductor processing variables. In operation, the conductivity of the first transistor inversely controls the conductivity of the second transistor that supplies a compensated power to the inverter stages. The compensated power controls the conductivity of the transistors in the ring oscillator and the corresponding frequency of oscillation.

摘要： A tire building drum is described as having, a plurality of radially movable bead lock segments at each end of the drum for holding the tire bead rings during the turn-up operation, a pair of turn-up bladders, and a pair of carriers which work in conjunction with the bead lock segments and turn-up bladders to tension the ply endings of the unvulcanized carcass ply or plies as the ply endings are turned up and reversely wrapped around the tire bead rings to anchor the rings to the unvulcanized tire carcass for further processing.The carriers span the bead seats of the bead lock segments and snugly fit around the adjacent turn-up bladders, so that the bead lock segments, upon radial expansion, pull against and distort the shape of the bladders which react to regain their shape and/or position by pushing back against the carriers to tension the carriers which are in contact with the ply endings and which tension the ply endings during turn-up to eliminate, adjacent the tire bead rings, the formation of voids which entrap air and adversely affect the adhesion between the tire bead rings and surrounding rubber material. A lubricant is provided between the contacting surfaces of the carriers and turn-up bladders to permit relative, unimpeded movement between these two components.
摘要翻译：轮胎成型鼓被描述为具有在滚筒的每个端部处的多个可径向移动的胎圈锁定段，用于在上起操作期间保持轮胎胎圈环，一对上起的囊和一对托架，与胎圈锁定段和上翻气囊一起工作，以在帘布层顶端翻转并反向缠绕在轮胎胎圈环周围以将环固定到未硫化轮胎胎体上时张紧未硫化的胎体帘布层或帘布层的帘布层末端进一步处理。载体跨越胎圈锁定段的胎圈座并且紧密地配合在相邻的上升气囊周围，使得胎圈锁定段在径向膨胀时拉动并扭曲气囊的形状，其反应以恢复其形状和/ 或通过向后推靠在托架上的位置来拉紧与帘布层末端接触的载体，并且在翻起期间张紧帘布层末端以消除邻近轮胎胎圈环的空隙的形成，这些空隙会堵塞空气并不利地影响轮胎胎圈环和周围橡胶材料之间的粘合。在载体和上翻气囊的接触表面之间提供润滑剂，以允许这两个组分之间的相对而不受阻碍的移动。
