A scalable stack-gate flash memory cell and its contactless memory array are disclosed by the present invention, in which the control-gate length and the implanted region of a scalable stack-gate flash memory cell are separately defined by two sidewall dielectric spacers formed over a sidewall on the common-source region and, therefore, can be controlled to be smaller than a minimum-feature-size of technology used; a contactless memory array comprises a plurality of common-source/drain conductiv...

The article includes a first piece (7) provided with two flexible lugs adopting, in the absence of any force, a position of rest in which they can, over a certain length, be inserted without effort into an opening (6) in a support (1), and a second piece (30) having a fixing foot (32) adapted to cooperate with the first piece so that the fixing foot can be inserted through the first piece (7) as far as a configuration of locking on the support in which the fixing foot (32) keeps the flexible lug...

An optical connector is disclosed which includes self-closing shutters to protect the optical contacts from environmental contamination when male and female portions of the connector are disconnected. The optical connector is comprised of male and female portions having means for permitting interconnection while the male and female portions are slightly axially misaligned. Male and female portions of the optical connector each contain one or more spring loaded optical contacts protected by a shu...

Connection for, on the one hand, a male ejection joining piece (23) of a fuel cartridge (20) intended to supply compressed gas to a compressed gas attachment device and, on the other hand, a male inlet joining piece (32) of a device (30) for inletting compressed gas into the device, comprising sealing means (11) intended to ensure the sealing tightness of the connection between the two joining pieces (23, 32) and a female seal support (1) arranged to receive the two male joining pieces (23, 32)....

A plug and an adapter are provided for use with an existing electrical receptacle which has a sleeve extending from a mounting base, with a conductive pin within the sleeve. The adapter has a cylindrical collar receivable snugly over the sleeve of the receptacle, and includes a flange for maintaining the collar in a predetermined position on the sleeve. The plug is elongate, with a first end having a recess for receiving the cylindrical collar, the first end also having an electrically conductiv...

A control device for molecular sieve on-board oxygen generating systems measures both temperature and pressure of the inlet air of an oxygen generating system. An electronic control unit applies pressure limits to a pressure measurement signal and combines it with a temperature measurement signal to produce a composite analog signal responsive to both temperature and pressure inlet air conditions. This analog signal is linearly converted to a frequency signal, whereupon the frequency signal is d...

A low inductance large area coil (LILAC) is provided as a source for generating a large area plasma. The LILAC comprises at least two windings which, when connected to an RF source via impedance matching circuitry, produce a circulating flow of electrons to cause a magnetic field in the plasma. Because the LILAC employs multiple windings, few turns of winding are required to obtain a large area coil, so that the inductance of the LILAC is low. The low inductance of the LILAC ensures that the sel...

A gel-fiber glass (GFG) is a newly-formed sol-gel glass polymerized from tetramethoxysilane on the surface of activated glass wool fibers or activated fibrous glass. GFG is a support for trapped chemical or biochemical reagents. A thin layer of reagents trapped in gel glass during its preparation is present on the surface of a lattice of glass fibers. Columns for affinity chromatography were prepared from the GFG membranes with entrapped antigens or antibodies and were used to isolate different ...

At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data st...

In a multiprocessor system in which a master processor and a plurality of slave processors access in common a page mode memory, each slave processor functions such that upon completion of a memory access by the slave processor, the page address which was being accessed prior to that access by the slave processor is reloaded into the page buffer of the memory. Since in general each access by a slave processor is preceded by and followed by an access by the master processor, generally to the same ...
