For producing the first differential of a two-dimensional optical image, an image of electrical charges corresponding to the brightness distribution of the image is produced in a first layer of an optical structural element. The first, electrical charges storing layer includes a plurality of light sensitive detector elements arranged in a mosaic-type pattern (D.sub.i). The electrical charge image representing the brightness distribution is converted into a transmissivity or transparency distribution corresponding to the potential differences across said detector elements in the first layer, by a second layer made of a material (M) that is electro-optically modulatable for changing the transparency or degree of transparency.

A liquid crystal light modulator is constructed for the transmission of sch signals modulated onto a light carrier passing through gaseous, liquid, and solid media such as air, water, or glass. A large surface area modulation of the light is accomplished in the visible and infrared range over narrow, however adjustable, wave length ranges or widths. Several circuit arrangements for such modulators are disclosed and their function described.

The invention relates to a photocathode for the infra-red range having a plurality of layers of semi-conductive and conductive material. The photocathode is transparent and sensitive in a spectral range of between approx. 1 and 20 .mu.m. This is achieved by the following layer structure:p.sub.1 : a highly doped p-layern.sub.2 : a highly doped n-layeri.sub.3 : an intrinsic layerp.sub.4 : a highly doped p-layerm.sub.5 : a thin metal layer, preferably of an atomic layer of Cs.The spectral sensitivity can be adjusted by applying a negative bias voltage to the layer p.sub.1 with respect to the layer P.sub.4. When this happens, the Fermi level of the layer p.sub.2 is shifted and the work function of the electrons is reduced.

A coupling element (3) and a waveguide structure (4) are deposited on a common substrate (2) of an optical component (1). The coupling element (3) serves for the optical coupling of the waveguide structures (4) to a further optical component. The coupling element (3) contains a reflecting, curved surface (31.1-31.8) for deflecting and for collimation of light which propagates between the waveguide structure 4 and the further optical component. The coupling element (3) creates a standard for interfaces between the optical component (1) and a further optical component. The manufacture of the coupling element (3) is simple and inexpensive, may be standardized and directed to large batch numbers.

A postage meter module has a printing unit, a control unit connected to the printing unit, input/output devices connected to the control unit, and memory devices connected to the control unit. A configuration for an internal cost center printout includes a pixel memory having a field and at least one memory area for accounting data into which data are loaded and converted and/or from which data are read out and converted. The conversion is a blockwise orthogonal rotation of the pixel memory field. A device for orthogonal rotation of the pixel memory field permits a block of a print image with accounting data having been electronically rotated by 90.degree. or by 270.degree. in a direction of printing to be temporarily stored in or read out from the at least one memory area of the pixel memory. A print control unit reads out print image data corresponding to the accounting data by blocks from the pixel memory. A process for an internal cost center printout with a printing device for printing out variable information, includes switching over operation of a print head from printing postage for postal matter to printing a cost center printout.

A modular ink jet printer head has modules each having three spacers at their periphery in order to maintain a constant spacing between the modules. These spacers each have their base secured to the module and reside perpendicularly on a reference plane. The spacers of a module are brought into a detent engagement with at least those of one further, adjoining module. A base plate and two legs arranged at two first sides of the base plate form a U-shaped module carrier. Fastening elements for the modules are arranged at both second sides of the base plate and adjustment means are arranged at the legs. Offset stop edges for all modules are worked onto a side thereof parallel to one of the second sides of the base plate in the common opening of the base plates for the front edges of all modules. The reference edge of each module is brought into a detent engagement with an allocated stop edge of the base plate, so that a defined, lateral offset occurs between the modules.

A method for shipping electronically stored letter contents or communications and/or data on flat information carriers, particularly chip cards, requiring postal franking or prepaid postage, includes storing shipping data in at least one of a plurality of memory regions of the information carrier. The shipping data is read out with a read-write module. The shipping data is linked to a postage table being stored in memory, for calculating a postage value appropriate for shipment of the information carrier. An accounting or debit is made for the calculated postage value for the information carrier with a postage meter device. A postage imprint is printed on an item to be shipped. In an apparatus for carrying out the invention, the read-write module and the postage meter device are integrated into a unit.

A technique of operating a flow line is provided. The flow line includes two or more assembly stations for the assembly of a heavy machine. The technique involves installing a prepared assembly trailer in the flow line before or at a first assembly station. The prepared assembly trailer is connected to at least one flow line tow bar. If the prepared assembly trailer is installed before the first assembly station, then the assembly trailer is moved to the first assembly station. If not, all the flow line assembly trailers are moved to the next assembly station. The steps of moving the flow line assembly trailers are performed timewise stepwise.

A device for processing mail and charging required postage includes a standardized mail depositing device having a transport catch. A charging unit is connected to the mail depositing device for charging postage after mail has been inserted in the mail depositing device and for unlocking the transport catch. Secured storage containers receive mail from the mail depositing device. A method for processing mail and charging required postage includes inserting mail into a standardized mail depositing device having a transport catch. Postage is charged after the mail has been inserted in the mail depositing device and then the transport catch is unlocked, with a charging unit connected to the mail depositing device. The mail is fed into secured storage containers from the mail depositing device.
