| An image forming device is provided to realize the same function while reducing the number of parts by enabling a high voltage generator to apply voltage to all color developers including cyan, yellow, magenta, and black developers while using one transformer jointly. A plurality of developers(11-14) coat toner on a printing sheet. A plurality of transcription rollers(21-24) correspond to the developers respectively in a transcription belt(20). A switching unit(30) controls connection between a voltage generator(40) and the transcription rollers. A controller(50) enables the switching unit to supply voltage to the selected transcription roller. The controller enables the switching unit to supply wrong voltage to the selected transcription roller to collect the toner remaining on the transcription rollers. The controller enables the switching unit to supply the wrong voltage to the selected transcription roller when the amount of the toner collected by the collectors exceeds a predetermined value by detecting the amount of the collected toner. High voltage is applied to developing rollers(11y,12c,13m,14k) for jumping-development by which a developer is developed into a photo conductor. | ||||||

An electrolytic print head comprises a plurality of styli (16, 18) between electrically insulative laminae (38, 42, 48, 38', 432', 48') which space the sytli from planar reference electrodes (20, 22, 24). The head is formed by building two laminated elements respectively comprising insulating layers (34, 38, 42; 34', 38', 42') spaced by conducting layers (36, 40; 36', 40'). Parallel grooves are formed through layers (42, 40; 42', 40') extending into layers (38; 38'). The grooves are then filled with insulating material which unites the layers (38, 42; 38', 42') and separates the styli (16, 18). The two elements are then stacked with layers (24, 22, 20) to form the head. |

Die Erfindung betrifft ein Verfahren und eine Schaltungsanordnung für die Speisung von Druckelektroden in einem Elektroerosionsdrucker mit Treiberstufen für Zündimpulse relativ hoher Stromstärke und relativ kurzer Dauer sowie mit Treiberstufen für Ausbrennimpulse relativ niedriger Stromstärke und im Vergleich mit den Zündimpulsen von merklich längerer Dauer. Vom Prinzip her ist dies ein Verfahren mit zwei unterschiedlich starken Stromimpulsen, das dadurch ausgezeichnet wird, daß die jeweilige Treiberstufe für den Ausbrennimpuls zuerst und die Treiberstufe für den Zündimpuls erst nach einer relativ kleinen Verzögerung d betätigt werden, und daß dann, wenn der Ausbrennimpuls die Zündung innerhalb des Zeitintervalls d bewirkt hat, die über dem dann zwischen Elektrode und Aufzeichnungsträger entstehenden Lichtbogen abfallende Spannung das Wirksamwerden der Treiberstufe für den Zündimpuls verhindert. |

| Printing apparatus for use with electrosensitive paper includes a scanning means in the form of an endless belt 11 suspended between pulleys 13, 14 and carrying writing styli 17. The styli are scanned across the paper 15 as the belt rotates and writing signals are applied from a control circuit 24 via a conductor strip 19 to the stylus which is in contact with the paper. Stylus guiding surfaces 20, 21 are provided to keep the stylus running along a straight edge, and position signals are generated by a transducer 27, such as an optical encoder, so as to synchronise the writing signals. | ||||||

An electrode (10) for electrolytic printing on a printing medium (14) comprises a metal substrate, preferably of Ti, which has a thin layer (18) of TiO2 between 200Å and 1,000Å deposited thereon and a tip layer (12) of RuO2 between 5,000Å and 10,000Å on the TiO2 layer. The RU02 layer is at the extremity of the electrode which during the printing is in close proximity to the printing medium. This oxide layer provides an increase in wear resistance of about two orders of magnitude over non-oxidized electrodes. |

An address control appropriately places the stored bits to accommodate the spacing between electrodes for the respective data bits. | ||||||
| 16 | Suspension arrangement for an oscillating body | US974593 | 1978-12-29 | US4227455A | 1980-10-14 | William B. Pennebaker |
| A body, which oscillates or vibrates at resonance, is suspended from a support structure so that it has spatially linear motion along an axis for a relatively short distance. The body has two connected portions spaced from each other along the axis of motion of the body with each portion connected by leaf springs to a separate intermediate frame. The two intermediate frames are preferably disposed on opposite sides of the axis of motion of the body and connected by additional leaf springs to a main frame, which is suspended by leaf springs from a normally stationary support. If desired, the two intermediate frames may be driven out of phase with each other with one in phase with the body so that the body has a predetermined path different than spatially linear motion without materially affecting the amplitude of motion of the body along its axis of motion. | ||||||

| A portable electro-mechanical printer has a platen (1) over which electro-sensitive paper is advanced, relative to a print head (6) having a few row of selectively energizable needles (8) which is movable by an electric motor transmission (18,19,21,24) parallel to the platen in a scanning direction transverse the row of needles. A timing disc (25) is driven by the drive transmission, the disc being subdivided into sectors and cooperating with two relatively displaced photocells (26,27) which produce two periodic signals upon rotation of the disc, these signals being utilized to provide clock pulses controlling successive energizations of the print head needles as the latter is scanned across the paper. | ||||||
| 18 | Electrical stylus adjustment means and method for rotary electrical printer | US888970 | 1978-03-22 | US4203122A | 1980-05-13 | Olin B. King |
| The printer records images in the form of dots on electrical discharge-sensitive paper. Three groups of five styli are mounted on a rotor. The paper is fed continuously through a curved guide in a direction perpendicular to the plane of rotation of the rotor. A disc is mounted on the same shaft and rotates with the rotor. The disc is transparent but has opaque lines spaced around its edge with a spacing corresponding to the desired spacing between dots. This divisional patent is directed to the feature in which three detectors, each comprising a lamp and photocell combination, detect the lines and produce corresponding timing pulses which are used to enable the styli. Each group of styli is enabled to operate only when it is in proper printing position. Location of the stopping and starting positions for two of the three groups is controlled by changing the time lapse between the enablement of adjacent groups. This is used to adjust the alignment of printed characters by simply moving the detectors relative to one another, thus avoiding movement of the styli and the attendant problems caused by such movement. | ||||||
| 19 | Mounting structure for rotary electrical stylus device | US888964 | 1978-03-22 | US4178599A | 1979-12-11 | Olin B. King |
| The device records images in the form of dots on electrical discharge-sensitive paper. A plurality of styli are mounted on a rotor. The paper is fed past the rotor. The paper has a coating which is eroded away by sparks between the styli and the paper. This divisional patent is directed to the provision of a support structure which supports the device with the coated side of the paper down so that when it is recorded on any debris caused by the erosion will fall away from the paper under the force of gravity and will not accumulate near the styli. | ||||||
| 20 | Rotary printing method | US888975 | 1978-03-22 | US4178583A | 1979-12-11 | Olin B. King |
| The printer records images in the form of dots on electrical discharge-sensitive paper. A plurality of styli are mounted on a rotor. The paper is in strip form and is fed continuously through a curved guide in a direction perpendicular to the plane of rotation of the rotor. Each stylus is energized by a voltage sufficient to create an electrical discharge between the paper and the stylus, in accordance with a code supplied from an electrical memory in which the codes for the character images are stored. This divisional patent is directed to the feature whereby words and sentences are formed longitudinally on the strip. Several lines of text can be formed on the strip, and a whole page of text can be printed relatively quietly and at a relatively high speed and low cost. Characters forming one message are stored in memory. Then they are read out in the sequence in which characters from different lines are to appear in transverse columns. The length of the lines can vary over a wide range. | ||||||
