    摘要: A system for braking an escalator or moving walkway includes a handrail and passenger support in registration with one another so as to move together. A braking tensioner selectively increases tension in the handrail during operation. The increased tension serves to frictionally brake the handrail and hence the passenger support. The braking tensioner may be located in any of various locations depending upon system design, and may be driven in any suitable manner, e.g., hydraulically, electrically, electromagnetically, and so on. Frictional wear on the handrail is reduced by the fact that the described braking system spreads the frictional load over a large area of the handrail, e.g., the many locations where the handrail contacts the underlying support throughout its length.

    摘要: A fast data transmission circuit for a semiconductor memory minimizes voltage variations of a data transmission line without the use of a separate data transmission voltage. The data transmission circuit includes a pair of input nodes, a data transmission line pair, a pair of sensing nodes, a pair of output nodes, and a control electrode. Prior to data transmission, the output nodes are pulled up to a high voltage state, the data transmission line pair is pulled down to a low voltage state, and the sensing nodes are held between the high and low voltage states. When the control pulse is applied to the control electrode, the sensing node voltage levels are transferred to the data transmission line pair by the sensing voltage transfer circuit. When one input node is pulled to a low voltage state, a corresponding one voltage level on one transmission line is changed, causing a corresponding change of voltage at one of the sensing nodes. The voltage difference at the sensing nodes causes a corresponding one of the output nodes to go to a low voltage state while the other output node remains at the high voltage state.

    摘要: A method for detecting an overvoltage signal applied to a semiconductor memory device address pin reduces stress on the device and simplifies the testing process by dividing the voltage of the overvoltage signal and comparing it to a reference voltage, thereby generating a difference signal. The difference signal is buffered by a drive stage which generates a test mode output signal that places the memory device in a test mode. An overvoltage detection circuit for implementing this method includes a comparison signal generator having a resistive voltage divider for dividing the overvoltage signal and generating a comparison signal. A differential amplifier compares the comparison signal to a reference signal from a reference signal generator. The differential amplifier generates a difference signal which is coupled to a drive stage which generates a test mode output signal. The comparison signal generator, the differential amplifier, and the drive stage can be enabled in response to a test mode enable signal.
