Patent EP-0020851-A1 (EP)
Inventor: FILLMORE GARY LEE
IPC: G06K15/10
Filed: 1980-02-28
Abstract: The flight path of drops from an ink jet printer nozzle are corrected to reduce print position error on the print media. It has been found that drops as far as 30 drop positions ahead of a particular drop in the ink stream can have an effect on the flight path of that particular drop to the print media. Using a memory to store 2 30  compensation values to correct the flight of the drop for all possible combinations of drop patterns in the ink stream is not practical. A smaller number of compensation values are used to correct the flight path by grouping the drops remote in position from the drop being compensated into blocks of drops and treating each entire block of drops as contributing one effect on the flight of the drop. Accordingly, drops D 1  to D 7  close to the compensated drop are treated as having an individual effect on the flight path while drops remote from the compensated drop R are grouped into one or more blocks A, B, C and each block is treated as having a single effect on the compensated drop R.

Abstract: The invention provides a rectifier circuit, particularly suitable for use with inverter and transformer power supplies, stabilised against a fall in input voltage. The supply is applied through inductors (L1.L2) to a full wave diode bridge rectifier (CR1, CR2, CR3, CR4) having a pair of capacitors (C1, C2) connected across its DC output and a controllable bi-directional current device (CR5) connected between the common point of the capacitors, and at least one of the bridge inputs. A control circuit 21 switches on the bi-directional current device for part of each cycle in response to a drop in output voltage causing the circuit to function at least partially as a voltage-doubler rectifier. The control circuit may compare an error voltage derived from the output with the voltage from a ramp generator to provide pulses for switching the bi-directional devices. 
     In a three-phase version of the circuit (not shown in Figure 3) inhibit circuits are provided to prevent more than one of the bi-directional devices becoming conducting at any one time.

Abstract: Printhead assembly for a printing mechanism of the kind that swipes a printhead (109) along a ribbon (116) in producing marks on a receiving medium (106) mounted to pivot and includes a ribbon guide (36) that serves to wrap the ribbon around the trailing side of the printhead (10). The assembly is positioned to permit the printhead (10) to be rotated to a normal printing position at a printing line. By so arranging the ribbon path that the ribbon directions for arrival and departure of the assembly intersect the pivot axis, essentially zero resultant torque may be applied to the assembly by ribbon tension forces and the printing pressure at the receiving medium is, accordingly, unaffected by ribbon tension variations.
