Title: Process for working up reaction gases during the oxidation of HCl to chlorine
Inventor: GESTERMANN FRITZ
IPC: C01B7/07
Filed: 1996-09-20
Granted: 1999-12-01
Abstract: In the process of working up the reaction gas consisting of chlorine, hydrogen chloride, oxygen and water vapor produced in a chlorine reactor, the reaction gas leaving the reactor is first cooled until the water of reaction and hydrogen chloride condense in the form of concentrated hydrochloric acid. The concentrated hydrochloric acid is then separated from the reaction gas in a phase separation column and discharged. The remaining reaction gas, from which the substantial proportion of the water and a proportion of the hydrogen chloride have been removed, is then post-dried in a drying tower. The post-dried reaction gas consisting of chlorine, oxygen and hydrogen chloride is then compressed to 1 to 30 bar by a compressor. In the subsequent stage, the compressed reaction gas is passed through a cooled chlorine recuperator, wherein the chlorine is very largely liquefied. Finally, the components of the reaction gas, which could not be condensed in the chlorine recuperator, are at least partially returned to the reactor.

Title: Method of manufacturing semiconductor memory cells and the same apparatus
Inventor: MATSUOKA HIDEYUKI
IPC: H01L27/108
Filed: 1997-09-17
Granted: 1999-12-21
Abstract: As the capacity of DRAM keeps on increasing, the problem of height jump between COB memory arrays and periphery circuits is getting more serious. Although there were proposals of pre-arranging the height on semiconductor substrates, it cannot meet the demand of one giga bit DRAM chips, nor the shallow trench isolation application. The present invention creates an interlayer insulation film behind the bit lines and over the periphery circuit, partially covering the latter. This invention can effectively moderate the height jump between memory array and periphery circuit, such that no extra work is needed to adjust the height of semiconductor substrate. Ordinary planar substrate will suffice and shallow trench isolation can be applied in this case. It also allows periphery circuits to be connected to multiple via plugs by lifting the surface, without enlarging holes or burying metal plates, thus enhancing the chip reliability.

Title: A receiver and method of operating a receiver
Inventor: KRISHNAMURTHY GOPALAN
IPC: H04N5/46
Filed: 1997-10-06
Granted: 1999-05-01
Abstract: A receiver for receiving a cable and terrestrial digital signals of differing VSB modes where the data levels of the various signals have a desired relationship that enables simple data level slicing and error determination. Some of the signals have sync levels that do not conform to the desired relationship and the receiver includes a comb filter for reducing interference when receiving an 8VSB terrestrial signal. The mode of the received signal is determined and a correction factor is applied to the syncs of the signals as needed to reestablish the desired relationship. Operation of the comb filter results in additional levels and a disruption of the desired relationship. For such cases, the comb filtered data levels are modified to make them a subset of the VSB 16 data levels. The modifications are accomplished in feedback paths of the phase tracker after the circuit equalizer and do not affect the data levels passed to the next stage.
