Patent EP-0110314-A2 (EP)
Inventor: TASHIRO KOREFUMI
IPC: B60L3/08
Filed: 1983-11-23
Abstract: A time division multiplex data transmission system. A particular time slot (58) among those for data transmission is placed with alternation of different data modes such as "1" and "0" in a commanding station destined for issuing commands. The alternation of data modes is supplied to receiver stations together with other data. When alternation of data modes is detected at the particular time slot in the receiver station, the reception of one command signal from the commanding station is confirmed, while detection of disappearance of the alternation of data modes indicates other command. Since a fault in the data transmission system results in generation of a fixed data mode or level such as "1" or alternatively "0", the alternation of data modes and disappearance thereof can define the commands discriminatively from the state brought about by the fault. Fail-safe feature can thus be realized.

Abstract: Beschrieben wird ein Verfahren zur Herstellung lagerstabiller wässriger Farbstofflösungen von wasserlöslichen Reaktivfarbstoffen, ausgehend von einer wässrigen Lösung oder Suspension des rohen Reaktivfarbstoffs, welche mittels Membrantrennverfahren aufkonzentriert und zumindest teilweise entsalzt wird. Das verfahren ist dadurch gekennzeichnet, dass man einen Teil des Wassers, welches der Farbstofflösung bzw. -suspension während des Membrantrennverfahrens entzogen wird, laufend durch entmineralisiertes Wasser ersetzt, wobei der Gehalt an Calcium- und Magnesiumionen in der Farbstofflösung nicht über einen Wert von 0,01 Gew.% steigt. Die aufkonzentrierte und entsalzte Farbstofflösung wird durch Zusatz eines Polyphosphat- oder Dihydrogenphosphat/Polyphosphat-Puffers stabilisiert; gegebenenfalls gibt man eine, die Wasserlöslichkeit des Farbstoffs verbessernde Komponente zu. Die so erhaltenen Präparate sind während mehrerer Monate bei Temperaturen von -10°C bis +40°C einwandfrei haltbar.

Abstract: Disposed between two base plates with control electrode is a cholesteric liquid crystal which exists in two optically different, stable structures and has a dielectrical anisotropy which is positive at low frequencies and negative at higher frequencies, as a result of which the liquid crystal assumes one of the two stable structures as a result of applying a low-frequency voltage and the other stable structure as a result of applying a higher-frequency voltage. The two optically different structures have long-term stability with no voltage applied. This makes energy-saving displays possible. <IMAGE>

Abstract: Afield of image information is processed with operations on a relatively coarse representation of the full field and with operations on a high resolution representation of only a portion of the full field. The partial results from operations on field portions may be formatted to yield a composite result for the full field. 
     A photographic record of the image information may be read to provide the full-field representation and read again to provide the field-portion representation. 
     This portion-by-portion processing of image information stored on a photographic record enables a computer with comparatively small memory capacity to execute relatively complex image processing tasks.

Abstract: A process for preparing ferroboron comprises first heating a mixture of boron oxide or boric acid, iron or iron oxide, carbon, and a carbohydrate to produce a foraminous char. During a subsequent two-stage reduction process in an electric or arc plasma furnace, ferroboron is produced and gaseous boric oxides are evolved. The boron values are captured as they move to the cooler regions of the furnace, resulting in high boron yields. The process is particularly useful in preparing pure and inexpensive raw material for the production of amorphous ferroalloys.

Abstract: Semi-finished products of stainless austenitic Cr/Ni(Mo) or martensitic Cr(Mo) steels are produced from rolled raw material directly from the rolling heat, avoiding interannealing, by quenching the workpiece (1) in water by means of quenching sprays (7) fed from a water tank (6), either directly (curve b) from a sufficiently high rolling end temperature corresponding to the solution annealing temperature (minimum quench temperature) or after additional heating to the quench temperature (curve c) by means of inductive heating (5) or from a temperature held by means of roller heating (3) approximately at the required quench temperature (curve d). The process sequence is here controlled by means of temperature monitoring of the workpiece (1), detected by a pyrometer (4), via a control instrument (9) feeding the set parameters, and a controller (8), the speed of the rollers (2) also being taken into account. <IMAGE>

Abstract: A unique CVSD CODEC is provided utilizing switched capacitor technology. This CVSD CODEC includes a syllabic filter which provides one of a large number of possible step sizes, thereby allowing the CVSD CODEC to accurately track and convert a wide range of input voltages. The CVSD CODEC includes coincidence logic, which determines how accurately the input voltage is being tracked, and a syllabic filter which provides an appropriate step size based upon the output signals of the coincidence logic. Large step sizes are provided for converting input voltages having large magnitudes, and small step sizes are used to convert input voltages having small magnitudes, thereby providing the very accurate resolution of input voltages over the wide range of magnitudes, while minimizing the bit rate required.

Abstract: A method and apparatus for generating a representation of a half-tone image including areas of different resolution is described. The apparatus comprises stores (2, 26) for storing digital colour data representing colour density information at low and high resolution respectively. A second store (25) stores the spatial data indicating the type of image data to be used at each position on a record medium (7). A third store (2') is provided for storing half-tone dot information. A group of six light modulators (10) which generate six scanning beams are arranged side-by-side. A support (8) supporting the record medium (7) to be exposed to the scanning beams is provided while drive motors (6', 9') cause relative movement between the support and the scanning beam. Scanning beam control means (25, 27-32) determine the position of the beams relatively to the record medium (7) in use, compare the current position with the stored spatial data and control the beam in response to the previously generated digital colour data and in response to the half-tone dot information. The plurality of beams are controlled together and at a first rate in response to low resolution data and singly or in groups and at a higher, second rate in response to high resolution image data.

Title: Apparatus and method for driving ink jet printer
Inventor: RICH LEONARD G
IPC: B41J2/07
Filed: 1985-05-24
Abstract: A circuit and related method are provided for driving an ink jet printer to achieve a consistent velocity of ejected ink drop despite differences in the time elapsing between successive drops. Timing pulses timing the ejection of drops each trigger the production of fundamental waveform. This waveform is then multiplied by a multiplying factor selected from a look-up table in response to the time elapsing between the timing pulse causing the generation of the waveform and the preceding timing pulse, and the modified waveform so produced is used to drive the printing head through a power ampilfier. The multiplying factor is one chosen by experiment as that required to produce the desired ink jet velocity. In a preferred embodiment both the fundamental waveform and the multiplying factor may each be obtained through the use of an associated PROM so that the waveform shape and multiplying factor versus dot frequency characteristic may be readily changed to suit the particular printer head in question.

Abstract: Austenitic cast iron has excellent corrosion resisting properties and has been preferentially used in machines or machine parts intended for handling corrosive fluids such as seawater. Cases, however, have been reported of machines or machine parts made of austenitic cast iron failing after they had been put to prolonged service at relatively low temperatures. The present inventors have located stress corrosion cracking as the cause of this failure. The present invention therefore provides a method of preventing the occurrence of such stress corrosion cracking in machines or machine parts made of austenitic cast iron by subjecting them to cathodic polarization, such cathodic polarization preferably being such that the applied potential is at least 50 mV more base (less noble) than the stabilized natural potential.
