Dummy information of a third level, which is between first and second levels written in a plurality of memory cells, is written in a dummy memory cell from a source node through transistors. Thus, a potential difference is caused between a read bit line and a dummy read bit line in reading. A potential comparison circuit indicates the level of information read from any memory cell on the basis of the comparison result as to the potentials of the dummy read bit line and the read bit line. Thus, t...

A dynamic memory comprises a control circuit for controlling the selection of the row decoder and the activation of the sense amplifiers in accordance with a RAS signal externally supplied thereto and a word line control circuit for controlling a selected word line to turn the electric potentials read out from the memory cells connected to the word line on the bit lines connected to the respective memory cells back to an inactive level after the electric potentials are sensed and amplified by th...

A radial seal and facial excluder seal are mounted on separate rings but installed in combination so that the excluder seal always maintains sealing engagement with its intended counterface notwithstanding wide axial assembly tolerances between the shaft and bore on which the seals are mounted, the excluder seal also serving to prevent contamination from coming into contact with the radial seal, and the ring on which the excluder seal is mounted serves as a guide for installation of the shaft pa...

There are dynamic sensors whose plunger is seated in the center of at least one diaphragm. In certain instances of use it is not possible to protect the sensitive diaphragms against inappropriate handling. For example, dynamic sensors are employed in the textile industry as yarn tensile force sensors. The diaphragm in which the yarn feeler is seated, which faces the yarn travel path, cannot be protected by means of a cover against unintentional touching, since dust accumulations between the cove...

A dynamic damper for absorbing vibrations in a rotary driveshaft, including a cylindrical mass member having an inner surface and an outer surface, a plurality of elongated connecting members each connecting member extending radially inwardly from the inner surface of the mass member thereby defining a plurality of spaced apart attachment surfaces wherein the cylindrical mass member is affixable to the rotary driveshaft such that the plurality of spaced apart attachment surfaces contacts the rot...

An apparatus and method receive and process information, and adapt the operational characteristics of the processing in response to material included in the received information. More particularly, the apparatus and method embody a software-controlled process which adapts or modifies the software in response to the received information. One embodiment is described in connection with a motion picture film which carries a conventional analog SVA soundtrack and a digital soundtrack with a digital r...

A dynamic memory includes a plurality of cells including capacitors connected by columns to bit lines and by rows to selection lines. An even row and an odd row contain reference cells, the cells of the other rows being memory cells. The capacitors of the reference cells have the same value as the capacitors of the memory cells. Means are also provided for, prior to reading a memory cell of an even row, connecting the selection line of the odd row of reference cells to an element having the same...

A method of dynamic resource allocation in a stratified network structure having a dynamically switched first stratum network and at least a second stratum network underlying the first overlying stratum network. At least a first route in the first stratum is provided with a first relation which points out two access points in the second stratum. A connection between the access points in the second stratum network is established and includes a second number of resources generally referred to as a...

In a dynamic RAM having a memory cell array in which a dynamic memory cell is arranged at an intersection between a word line and one of a pair of bit lines, a select level signal corresponding to a supply voltage and an unselect level signal corresponding to a negative potential lower than circuit ground potential are supplied to the word line. A signal of a memory cell read to the pair of bit lines by a sense amplifier that operates on the circuit ground potential and an internal voltage forme...
