Abstract: In forming an image by the simultaneous light exposure-transfer process using a photosensitive toner (6), a light-exposed electricity-removed toner is effectively scraped without bad influences on the image density, and the fog density is drastically reduced. 
     In subjecting a photosensitive toner layer (6a) to imagewise light exposure to form a combination of an electricity-removed toner and a charged toner and removing the electricity-removed toner from an electroconductive substrate (1) by contact with a magnetic brush (8), the flux density distribution of a main developing pole (4) in a developing sleeve (2) is set so that a two-peak flux density distribution having two peaks separated on the upstream side and downstream side with the vicinity of the nip position between the developing sleeve (2) and electroconductive substrate (1) being as the center is produced in the tangential direction and the value of the peak on the downstream side is smaller than the value of the peak on the upstream side.

Abstract: A method is provided for positioning an image frame recorded on a photographic film at a predetermined position for printing process. In the method, an image frame edge is detected depending on a quantity of transmitted light passing through the photographic film during carrying. If there is a faulty image frame having an undetectable frame edge, a film carrying amount is determined depending on a recording tendency of normal image frames preceding the faulty image frame. Therefore, it is possible to compensate, for example, a feed pitch error by a camera, and to position the image frame accurately. Further, it can be selected whether the image frame is a standard size image frame or a panoramic size image frame depending on the quantity of transmitted light. Thus, the printing process can be consecutively performed by positioning only one of the two type image frames so that an operation efficiency can be improved.

Abstract: Controlling the metering of carbon-source addition to the denitrification step of a waste water purification plant can be achieved by monitoring the methane concentration in the exhaust gas of the denitrification step and controlling the carbon-source feed in such a manner that the methane concentration in the exhaust gas remains at / 0.03% and in particular in the range from 0.2-0.4%, especially 0.2-0.3%. The redox potential in the effluent of the denitrification step is expediently additionally monitored and, if desired, kept at values in the range from -340 to -470 mV by additional carbon-source-feed control, the carbon-source feed being preferably spontaneously released if the redox potential exceeds -100 mV. An apparatus suitable therefor includes a methane metering device connected to the gas space of the denitrification and a metering regulator in the carbon-source feedline to the denitrification step, which controls the feed in proportion to the deviation from the set point determined by the methane measurement, and, if required, a redox potential measurement probe connected to the metering regulator and arranged in the effluent of the denitrification step, whose signal is passed to the metering regulator as an additional control parameter for the carbon-source feed. <IMAGE>

Abstract: An integrated circuit memory is disclosed which has its primary memory array arranged into blocks and which has redundant columns, each of which can replace a column in any one of the blocks. The redundant columns are selected by way of a redundant column decoder, associated with each column. A plurality of redundant sense amplifiers are each associated with selected redundant columns. Each of the redundant column decoders includes a set of address fuses for storing the column address responsive to which its associated redundant column is to be selected, and which are in series with pass gates which are turned on when redundancy is enabled, and turned off otherwise. This arrangement of address fuses and pass gates reduces and balances the loading of the decoder on the address lines, may be implemented with fewer transistors and thus in reduced chip area relative to conventional decoders, and also reduces the propagation delay through the decoder. The coupling of each redundant sense amplifier is controlled by a redundant multiplexer associated with each of the input/output terminals. Each redundant multiplexer receives the redundant column select signals from each redundant column decoder corresponding thereto, and includes fuses which indicate if its input/output terminal is to be placed in communication with its associated sense amplifier upon selection of a redundant column.

Abstract: The basis of obtaining the system presented here is a modular combination of a person-related first unit with a transmittable/receivable memory element via an antenna, which unit, alone or together with a further unit, works with an additional, but different identification part, and of a non-person-related, but object-related second unit for interaction between person and object, and with means for monitoring and maintaining the interaction, by means of which the units and objects are interlinked. The person-related first unit is bearer-oriented.

The object-related second unit is place-oriented. It is located in fixed places (for example, doors on buildings), and therefore has fixed coordinates or else is arranged fixedly on movable objects (for example, vehicles). <IMAGE>
