Abstract: According to the process for sending electronically memorised letter contents by means of flat information carriers, for example chip cards, the letter contents are written into the information carrier by means of a write/read module, while synchronously with this the dispatch data, such as address, kind of dispatch and advertising field, are transmitted to a franking device. The franking device calculates and books the respective transmission fees and prints a franking print on the dispatch piece used for transmitting the information carrier. <IMAGE>

Abstract: An output buffer provides for additional current sinking or sourcing capability by switching in an additional transistor (M6) when the output voltage (V OUT ) passes a given level. This allows the output buffer to supply DC current to a load without requiring an excessively large AC drive capability, which could undesirably increase switching noise. In a typical embodiment, an inverter (104) senses when the buffer output voltage reaches its switching threshold (approximately V DD /2), and turns on the additional transistor (M6) after a given delay. For example, a CMOS output buffer driving a TTL load may obtain additional current sinking capability by this technique. On-chip buffers (e.g., bus drivers and clock drivers) can also benefit from this technique.

Abstract: A method of transforming a video image includes sampling a digital video signal at a higher frequency f₂ than a usual frequency f₁ (1) and storing the sampled signals (2). The stored information is interpolated (3) and addressed so as to create a video signal representing a required transformation, the frequency of the video signal being reduced to the usual sampling frequency f₁ (4). The method can be applied for enlarging and reducing the video image. Where the image is reduced, the reduction is limited to prevent the effect of interference between Fourier spectral harmonic bands and a fundamental band of the components of a reduced video image signal when it is created from the stored information. Preferably, the reduction is limited to provide gaps or guard bands which prevent this interference.

Abstract: The invention relates to an arrangement for determining the roll angle position of a rotating projectile, shell, missile or the like with the aid of polarised electromagnetic radiation, comprising a transmitter (Fig. 3) arranged to emit a position-determining polarised radiation in the direction towards the projectile and a receiver arranged in the projectile (Fig. 4) in order to receive the transmitted radiation. The emitted radiation consists of two components, on the one hand a component in the long-wave band (LF) and on the other hand a component in the microwave band. The microwave component comprises a pulse train in which the pulses are intended to indicate when the long-wave component is situated in a certain phase position, for example to indicate the sinusoidal long-wave component's zero cross-overs with a positive-going derivative. This takes place in such a way that a synchronising pulse is emitted by the long-wave transmitter to the microwave transmitter which transmits a short series of microwave pulses (13) as an indication to the projectile.

In each bonding surface of a spacer (3) which is bonded to both front (1) and rear (6) panels, a positional deviation or displacement of the spacer with respect to the front panel, the rear panel or a shielding electrode is prevented by emplying a stepped portion on said rear panel (6) fitting with said spacer (3), whereby there is obtained a light emitting device of high accuracy free of variations in luminance, and it is made possible to reduce a dead space between adjacent light emitting devices and thereby attain a display of high resolution. In order to obtain such display, the front panel and the spacer, as well as the rear panel and the spacer, are respectively bonded through premolded frit glass (21). 
     Further embodiments include a method of fixing an anode by employing a plurality of elastic pieces on the outer periphery, said pieces being in contact with the inner side faces of the spacer and electrode leads having thermal expansion properties matched to the substrate and rear panel.

Abstract: A method is provided for forming isolated regions of oxide of an integrated circuit, and an integrated circuit formed according to the same. A pad oxide layer is formed over a substrate. A nitride layer is formed over the pad oxide layer. The nitride layer and the pad oxide layer are patterned and etched to form an opening exposing a portion of the substrate. The exposed substrate is then anisotropically etched to form a first trench region. A thermal oxide layer is grown over the exposed substrate in the first trench region and then etched to expose the substrate in the bottom of the first trench region. The substrate in the bottom of the first trench region is then isotropically etched to form a second trench region which extends laterally from the first trench region. The remaining thermal oxide layer, the nitride layer and the pad oxide layer are then removed. An oxide passivation layer is grown over the substrate and in the first and second trench regions. An insulating layer is formed over the passivation layer and a portion of the first and second trench regions.

Abstract: A liquid crystal light valve projection system is provided with increased optical overshoot, and thereby decreased optical response time, by employing a liquid crystal mixture (52) having molecules substantially perpendicularly aligned to the face of the liquid crystal light valve electrodes (42, 70) and axially twisted. The axial twist of the liquid crystal molecules is provided by laying down alignment grooves (90, 92; 96, 98) for the liquid crystal mixture that are oriented with respect to one another, on the opposite alignment layers, by an angle of between about 45° and 90°. This mutually angled orientation of the opposed alignment grooves on the opposed alignment layers causes optical overshoot of the system to vary when the entire liquid crystal cell (34) is rotated relative to the output polarizer (18) about an axis perpendicular to the output face of the cell. This rotation of the cell (34) of twisted perpendicular liquid crystal relative to the output polarizer (18) allows a faster optical rise time to be achieved.
