Title: Combined random access and serial port dynamic video RAM - has memory array that can either be accessed via 4-bit parallel port or via 4-bit serial port
Inventor: OGAWA TOSHIYUKI
IPC: G11C11/401
Filed: 1992-02-19
Abstract: The semiconductor memory device comprises a memory array (2) with associated sense amplifiers (3) and an address buffer (10), together with input/output elements for both random access and serial operation. Row (13) and column (14) decoders and a parallel data input/output buffer (15) are used for random access operation via connectors W100 to W103, while an address counter (7), serial selectors (6a,6b), data registers (4a,4b) and a serial input/output buffer (5) are used for serial operation via connectors S100 to S103. A timing signal generator (16) provides internal control signals in response to the external RAS, CAS, WB/WE, DT/OE, SC, SE and SWE signals. The OEbar and WEbar external signals control the reading and writing of data to and from the serial buffer and are themselves governed by the SWEbar signal that is applied to the data registers and the output buffer to switch the serial operation mode. For image processing in CAD system. USE/ADVANTAGE - Single unit combines access capabilities of processor memory RAM with serial data features of video RAM. High speed switching between input and output modes.

Title: Controlling temp. in sec. pulverisers of flue gas mixt. for pulverised coal fired boiler - sub-dividing flue gases into high and low temp. streams when extracted into return feed
Inventor: STROEER KURT DIPL ING
IPC: F23N1/02
Filed: 1992-08-28
Abstract: During the control of the temperature in the secondary pulverisers of a PC pulverised coal-flue gas mixture for a PC-fired steam boiler, the flue gases are extracted from the furnace into the return feed. The volume flow of the flue gases is controlled according to the required temperature. The volume flow is subdivided into high temperature and low temperature streams directly after entry into the return feed. The low temperature streams are taken from the cooled wall areas of the furnace and/or from the cold gas circulation in the furnace, whereas the high temperature streams are taken from the middle circulation area. If the sec. pulveriser temp. exceeds the stipulated value the adjuster (11) is controlled through the measured value pick-up (16) and the signal line (17) such that the upper part (8) of the horizontal flue gas section channel (4) is divided by bulkheads.
