Abstract: An elevator control receives car calls for certain floors which are subject to a restriction of operation, but does not prevent the storage of these car calls. The car calls subject to the restriction of operation are only served during the trip in the opposite direction, if a load increase has been detected by a load measurement device during the change in the direction of travel. The restriction of operation is only cancelled during a predetermined time interval dependent on the movement of the car door and simultaneous occurrence of a load change caused by added travelers. Two storage cells are connected to the car call circuits for the car calls subject to the restriction of operation where an entered call, during a cancelled restriction of operation, is stored in the first storage cell and, during the restriction of operation, is stored in the second storage cell. A call stored in the first storage cell is transferred to the travel control of the elevator prior to the change of direction of travel and a call stored in the second storage cell is only transferred after the change of direction of the elevator.

Abstract: Pleated paper barrier type air filter elements are cleaned by a reverse air jet cleaning system which includes one or more specifically shaped cleaning air valves (74) in which a plurality of jet nozzles or orifices are arranged in a predetermined pattern to provide a totally enveloping air jet which is discharged into a flow tube immediately downstream of the clean air flow chamber of a generally tubular filter element. The jet pattern provides a temporary pressure seal within the flow tube and entrains a substantial amount of ambient air into the reverse flow jet to thoroughly flush elements to clean dust cake from the exterior surfaces thereof. The multiple jet arrangement reduces the overall space occupied by the reverse jet cleaning system and provides a larger mass flow of cleaning air. Multiple jet orifice valves may be configured in virtually any geometric shape to provide a desired jet pattern.

Abstract: A data input buffer is changed from an inactive to an active state after the reception of instruction for a write operation effected on a memory unit. The input buffer is a differential input buffer having interface specs based on SSTL, for example, which is brought to an active state by turning on a power switch to cause a through current to flow and receives a signal therein while immediately following a small change in small-amplitude signal. Since the input buffer is brought to the active state only when the write operation's instruction for the memory unit is provided, it is rendered inactive in advance before the instruction is provided, whereby wasteful power consumption is reduced. In another aspect, power consumption is reduced by changing from the active to the inactive state in a time period from a write command issuing to a next command issuing.

Abstract: A semiconductor memory device is tested by sequentially coupling a plurality of global input/output lines to a comparator which compares data bits from the global input/output lines sequentially rather than in parallel so as to reduce the number of output sense amplifiers. This reduces both the chip area, and the excessive current consumption caused by large numbers of sense amplifiers operating in parallel. The memory device includes a plurality of global input/output lines coupled to a memory cell array to receive data from the memory cell array. A global line select circuit generates sequential global line select signals during a test operation. A plurality of switch circuits selectively couples data from the global input/output lines to a sense amplifier responsive to the global line select signals. A comparator coupled to the output port of the sense amplifier sequentially compares a sequence of test data output from the sense amplifier and generates a result signal during the test operation.

Abstract: In a multi-carrier transmission system, a clock timing error ( tau e) is calculated at the receiver's side and used for synchronisation between a transmitting modem and a receiving modem (RX1). The clock timing error ( tau e) is calculated from phase errors ( phi 0,  phi 1, ... , phi i, ...,  phi N-1) detected for a plurality of pilot carriers during a tracking mode in such a way that the share (Ai) of a phase error ( phi i) detected for a particular pilot carrier in the clock timing error ( tau e) depends on the transmission quality (SNRi) of that pilot carrier over the transmission medium in between the two modems. In this way, the robustness of the synchronisation for narrowband noise near a pilot carrier is improved significantly. <IMAGE>
