Abstract: A memory with mechanisms for enhancing storage states without boosting voltages to levels that damage storage cell structures. A storage cell according to the present teachings includes a storage structure capable of switching storage states. A memory according to the present teachings includes means for writing the storage cell by applying a first voltage to a first node of the storage structure and for applying a second voltage to a second node of the storage structure such that the first and second voltages have opposite polarities.

Abstract: A memory which is capable of reconfiguration between a first mode in which each storage cell is capable of storing a pair of data bits and a second mode in which each storage cell is capable of storing a single data. A memory according to the present teachings includes a storage cell having a first structure and a second structure each capable of a storage state and mechanisms for reconfiguring the memory between a first mode in which the storage states of the first and second structures indicate a first and a second data bit, respectively, and a second mode in which the storage states combine to indicate a data bit.

Abstract: Process and apparatus for a non-destructive continuous automatic quality control system monitoring a stoneware pipe and like objects, where the pipe is excited with a vibration generator up to a resonance frequency vibration, this vibration being measured with a vibration receiver, thereupon being registered and compared with values of a calibration curve. During the excitation and measuring, the pipe is borne on two turn crosses coated with rubber. The resonance frequency vibration is measured at the maximum of at least one antinode of vibration. The pipe is transported by a conveyor belt having rollers. A photoelectric pipe scanning system measures the nominal diameter of the pipe for preadjusting the position of the vibration receiver.
