Abstract: An MOS memory cell (44) including an electrically-programmable and electrically-erasable storage device (46) fabricated on a semiconductor substrate (50) is disclosed. The storage device (46) is divided into sensing and programming sections (90,92), each of which sections comprises vertically-aligned floating gate and program gate portions (62L, 62R, 72L, 72R) respective formed from first and second electrically-conductive strips (62,72). A tunnelling region (60) is formed in the substrate (50) beneath the floating gate portion (62R) of the storage device programming section (92) and a thin tunnel dielectric (70) is interposed between the tunnelling region (60) and the programming section floating gate portion (62R) to faciliate tunnelling of charge carriers therebetween. First and second source/drain regions (94,96) physically isolated from the tunnelling region (60) are established in the substrate (50) in alignment with the sensing section floating gate and program gate portions (62L, 72L). The memory cell (44) additionally includes a selection device (48) comprised of first and second field effect transistor structures (98, 104) which can be activated during memory cell read, program and erase operations to supply selected unipolar potentials to the tunnelling region (60) and the second source/drain region (96) associated with the storage device sensing section. In particular, the first and second field effect transistor structures (98,104) may be used to simultaneously transfer ground potential from a memory cell write line (114) to the storage device tunnelling region (60) and second source/drain region (96), thereby preventing "read disturb" conditions from occurring in the thin tunnel dielectric (70) as the memory cell (44) is being read. The ability to transfer ground potential to the tunnelling region (60) and second source/drain region (96) also eliminates any need for maintaining a direct ground diffusion in the memory cell itself.

Abstract: The meter includes a liquid crystal cell (12) for detecting acoustic energy and a control circuit (14) for applying an electric field to the cell. The cell includes a liquid crystal material having elongated molecules. The preferred liquid crystal is in the form of a layer of the nematic type which is homeotropically aligned. The elongated liquid crystal molecules exhibit positive dielectric anisotropy wherein the dielectric constant parallel to the molecule's axis is greater than the dielectric constant perpendicular to the molecule's axis. In the unexcited condition, the nematic layer is dark. In the ultrasonically excited condition, the nematic layer exhibit birefringence. A restoring electric force can be applied to the liquid crystal material to suppress the acoustically-induced birefringence condition of the cell to the dark appearance associated with the unexcited condition. The strength of the electric field required to suppress the birefringence is proportional to the acoustic intensity of the ultrasonic beam or acoustic field applied to the cell.

Abstract: It is disclosed a looking device which allows the same single railway-truck to carry either containers and/or mobile boxes of traditional structure, having thus the standard flat bottom, or that special type of mobile boxes having a "tunnel" bottom which have a larger loading capability but, owing to said "tunnel" bottom, are presently susceptible and forseen to be transported only by road by suitable road-trucks. The height of the loading platform in conventional railway-trucks is in fact such as not to allow said special mobile boxes with a "tunnel" bottom to be transported because said special mobile boxes have a height exceeding that of the traditional containers and consequently the total height of said special boxes, once loaded upon a standard railway-truck, would be such as to exceed the standard allowed height in the railway-traffic. The device according to the present invention, exploiting the form of the "tunnel" at the bottom of said special boxes, allows said special boxes to be transported by a railway-truck where the longitudinal main frame of said truck, which constitutes the loading platform, may be comprised inside the dimension of said "tunnel", i.e. inside the two longitudinal main frame members of said "tunnel" bottom. The looking device comprises two plates supporting each a dowel: the first one being a fixed plate (2) solidarly jointed to a supporting shaft and providing a lower-level loading surface whereby a fixed dowel (3) is provided for coupling said mobile boxes having a "tunnel" bottom on to said railway-trucks; the second one being a mobile plate (4) carrying a mobile dowel (5), said mobile plate (4) being sliding fitted to said supporting shaft and providing a higher-level loading surface whereby said mobile dowel (5) is provided for coupling thereon containers and/or mobile boxes having the standard flat bottom. The mobile plate (4) supporting the mobile dowel (5) may assume various working and/or non-working positions whereby said working positions of said mobile plate (4) may or not overlap the position of said fixed plate (2). Said mobile plate (4) may also be tilted in a non-working position so as to ensure said railway-trucks equipped with said looking device to provide the largest flexibility in carrying either standard or special containers and/or mobile boxes; said special containers and/or mobile boxes being presently forseeen for transport by road only being of the type with a "tunnel" bottom. According to a preferred embodiment, said looking device makes it possible to lower the loading platform surface, for said special mobile boxes with a "tunnel" bottom, about 170 mm. below the standard level of a loading platform in a conventional railway-truck and this without any substantial modification to the standard main frame of said railway-trucks.

Abstract: The removal of impurities from exhaust gases takes place by cooling the exhaust gas by means of a circulation gas and condensing out of the impurities in two groups of reversible heat exchangers. Each group consists of two precoolers and one low temperature cooler. While the impurities condense out in one group, they are thawed in the other group. In order to simplify the control, only one precooler is used in each group, which is charged with two inside gases, namely, the exhaust gas and the circulation gas. Only two simple control systems which can be easily program-controlled are then required for the purification process. In addition, the temperature increase of the circulation gas in the circulation gas blower can be utilized for heating up purposes in the group to be thawed.
