摘要： A spring-charged wire dot print head having printing wires is provided with back poles paired up respectively with the cores of electromagnets for cancelling the magnetic flux produced by a permanent magnet, to eliminate the adverse effect of magnetic interference liable to occur in driving the adjacent printing wires. The adjacent pairs of cores and back poles are opposite to each other with respect to the polarity of the magnetic path of the magnetic flux produced by the permanent magnet.

摘要： In a wire dot print head having print wires extending through an opening of a guide nose, the guide nose comprises two halves. The print head may further comprise a wire guide which is fitted in the guide nose and through which the print wires extend, and the wire guide may be clamped by the two halves. In another embodiment, the half members have abutting surfaces provided with semi-circular grooves, which when the guide nose halves are assembled, form guide holes in which the print wires are slidably supported. The use of the two halves facilitates assembly of the print head and reduces noise.

A yoke member is fixedly attached to the upper surface of the fixed longitudinal side portion of the spring plate and has a plurality of recesses for loosely receiving the armatures therein, to exert the effect of a magnetic field on the corresponding armatures. A restrictor is located on the respective path of the respective rear end of each armature to limit the movement of the respective rear end of the armature. A driver drives the armatures and a guide guides the styluses. A fastener fastens the spring plate, the yoke, the restrictor, the driver and the guide to a base plate.

摘要： A wire driving mechanism for a wire-dot print head employs a piezoelectric element or a magnetostrictive element as a driver (5). To enable printing with a satisfactorily high print quality, the wire driving mechanism employs the extensional force of the driver (5) to pivot two generally parallel levers (3a, 3b) respectively having fixed ends. When the levers (3a, 3b) are pivoted, the free end of each of the levers (3a, 3b) is moved by a displacement which is a multiple of the extension of the driver (5). The respective displacements of the free ends of the levers (3a, 3b) are transmitted by a pair of support members (6a, 6b) to opposite sides of a driving member (8) at positions on different levels with respect to the longitudinal direction of the driving member (8). As a result, the driving member (8) is moved so that a print wire (7) attached to the driving member (8) is advanced in a printing direction.

摘要： A method of adjusting an ink jet head having at least one polarized electromechanical transducer forming an ink pressure chamber from which ink drops are ejected when the electromechanical transducer is deformed. The method includes the steps of performing a first polarization operation where the electromechanical transducer is polarized into saturation in a first direction, and performing second polarization operation where the electromechanical transducer polarized by the first polarization operation is polarized in a second direction opposite to the first direction so that the electromechanical transducer is polarized to a predetermined level.

The adjusting yoke (12) has the magnetic characteristics that the magnetic reluctance increases as the temperature increases. Although the flux generated by the permanent magnet (3) is changed due to the change of the temperature, that flux change is compensated for by the presence of the adjusting yoke (12).

摘要： A connector housing has an insertion slot for receiving a companion base board, a plurality of grooves defined in a housing bottom in a direction normal to the insertion slot, and a plurality of pin attachment holes disposed between the insertion slot and the grooves. Contact pins are approximately L-shaped and pivotally held in the pin attachment holes, respectively, in the vicinity of central bent portions of the contact pins. When the connector housing is attached to a base board and the companion board is inserted in the insertion slot, ends of the contact pins are connected to a circuit pattern on the base board and opposite ends of the contact pins are connected to a circuit pattern on the companion board. The base and companion boards are therefore electrically connected to each other substantially perpendicularly to each other.
