Title: Ink jet recorder.
Inventor: JOCHIMSEN DIETER
IPC: B41J2/20
Filed: 1986-07-07
Abstract: An ink jet recorder of the continuous jet type has a mounting block defining a reference surface. Nozzle units from which the ink streams are ejected are releasably keyed to the reference surface. An ink reservoir supplies electrically conductive ink to the nozzle units which selectively charge segments of the ink streams issuing from the nozzle units. Each unit also includes provision for accurately aiming the ink stream in both the x and y directions using simple knob controls. A deflection unit also releasably keyed to the reference surface downstream from the nozzle units. The ink stream is directed through a deflection unit mounted on the reference surface. Mating members are provided in said mounting block which corresponds with mating members on the deflection unit. This unit generates an electrical field which deflects the selectively charged segments of the ink stream issuing from the nozzle unit, from their predetermined paths so that they do not reach the recording medium; the undeflected portions of the ink streams form the printing on the medium. The deflection unit also includes provision for removing extraneous ink from the regions of the deflection field so as to minimize background coloration in the printing on the medium. A charged mist shield is provided in said deflection unit to further attract extraneous ink in and about said deflection unit. Vacuum means are provided to withdraw extraneous ink from said deflection unit, nozzle unit, and mist shield.

Abstract: Un appareil comprenant un convertisseur analogique-numérique ayant un certain nombre de chiffres comprend un amplificateur de gain variable (23) pour l'entrée (VA) dans le convertisseur (26). Si une valeur instantanée (21A) de l'entrée (VA) est inférieure à la valeur nécessaire pour saturer le convertisseur (26), c'est-à-dire pour utiliser tous les chiffres du convertisseur (26), le gain de l'amplificateur (23) est automatiquement positionné pour amplifier l'entrée instantanée (21A) jusqu'au niveau nécessaire pour saturer le convertisseur (26). Par cette amplification sélective des différentes sorties (VA), chaque valeur instantanée (21A) est convertie en numérique par l'ensemble des chiffres du convertisseur (26) et la résolution de l'appareil est identique pour toutes les entrées (VA) sans considération de leur grandeur. En outre, le convertisseur n'est pas sursaturé tel qu'il pourrait l'être si les différentes entrées (VA) étaient amplifiées par un gain commun.

Abstract: Method and device for speed difference measurement in strip casting where a melt (4) is pressed between a travelling belt (2) and a casting drum (1) rotating along with the belt. For measuring the speed difference between the speed of the travelling belt and the peripheral speed of the casting drum, the belt is provided on one side with a raster of alternately darker and lighter stripes, and a number of measuring zones (7) having the same width as that of said raster are arranged around the periphery of the casting drum. Each measuring zone (7) comprises a transducer built up of a number of photocells which, via optical conductors opening out into the measuring zones, can be activated by said raster. When, during the casting operation, a measuring zone has arrived at a given measuring region, the number of activated photocells is read. The same procedure is repeated when the same transducer arrives at the end of the measuring region. With knowledge of the extension of the measuring zones and the measuring region and of the number of photocells in each zone, the speed difference, expressed as a percentage, together with the difference in activated photocells can be calculated.

Filed: 1987-07-21
Abstract: A metal, such as titanium, from group IVb of the periodic table is used as the target in a reactive deposition process. Ionized inert gas (16) (for example, argon) bombards the target in a sealed sputtering chamber (15) to initiate sputtering of the target metal. Reactive gas (19), such as nitrogen, is admitted into the chamber to mix with the inert gas and combine with the metal atoms, that are dislodged from the target in response to the ion bombardment, to produce a metallic compound (titanium nitride) on a substrate. The amount of the reactive gas in the chamber (15) is closely regulated and held at a desired reference setpoint by a control loop (19-24) to maximize the rate of deposition of the metallic compound onto the substrate. In addition, the setpoint (42) is automatically controlled (44-48) in response to the amount of hydrogen in the sputtering chamber (15) (which hydrogen is proportional to the water vapor) in order to maintain the quality of the coating on the substrate, particularly the color and composition of the coating, despite the presence of undesired water vapor in the chamber.

Abstract: The hollow tack button shank (21) was connected, in particular, to a shank end (24) which widens out in a bowl shape and has to cut a hole (19) in the web (10) of carrier material during the tacking process. However, said end must be compressed on the outlet side of the web of carrier material in a deformation chamber (15) of a counter-holding part (14) during the tacking process. In this case, there was always a tendency to use one type of tack button for webs of carrier material of different thicknesses, for which reason there was a long shank. This led to difficulties during tacking and tack button shanks breaking off. The wall of the tack button shank is provided with axially extending longitudinal zones which have a different strength relative to one another in relation to the dimensional changes occurring during the tacking process. This requires crinkling. <IMAGE>

Abstract: Controlled by the central control processing unit (ZSt), which is responsible for switching operations, not only audible but also independent visual communication is provided in an exchange (VE). This can be carried out in parallel with a call which has been set up or when the terminals concerned are idle. A specific information block, selected from several possible information blocks which are stored in listed form in a memory (T), is displayed selectively at the required terminal without affecting switching system operations. The information which corresponds or is to be allocated to the selected information block is presented, for example, on the display (DL). In the case of special user configurations (e.g. Manager/Secretary systems), the permanent address allocation is predefined in the customer data store (KD) for this visual communication, i.e. wherein the actual speech path (switching device, PCM highway) is not occupied. The individual texts which are to be presented on the display (DL) via the control channel (c/d) may be selected from all the stored texts by means of, for example, a key permanently assigned to each text or through a corresponding procedure. <IMAGE>

Abstract: A scrambling circuit (VS) in the subscriber terminal (TEG) of a mobile telephone system is connected to the signal path via an analog/digital converter (A/D). The signal to be scrambled is digitised and supplied to a digital signal processor (DSP). This processor contains a preemphasis circuit (VV) for increasing the higher frequencies which changes the characteristic energy distribution of the human voice. Four frequency bands are transposed in accordance with a code in a frequency band transposer (FBT). This code is generated by a code generator (CG) and transmitted in the audio frequency band via a pilot tone transmitter (PS). Switching signalling is therefore not influenced. The high frequencies are decreased again by a deemphasis circuit (EZ). In a base station (BS), the code is provided for descrambling by a pilot tone receiver (PE). Signals from the base station (BS) to the subscriber terminal (TEG) are scrambled using the same code. Although the subscriber terminals (TEG) generate the code, they do not decode it. It is decoded by the base stations (BS) but these are only accessible to authorised personnel. <IMAGE>
