摘要： A printer of the dot matrix type has a series of hammers with pins that print on an underlying medium. The pins are released from magnetic retention by reversing the plurality of a permanent magnet. This is controlled by electro-mechanical drive circuits and logic circuits. The printer has a power supply which supplies an output of a voltage level for driving the electro-mechanical circuits connected to a ribbon drive, platen drive, paper feed, shuttle motor, and fans at a given voltage and the hammers at a different voltage. A thermal sensor is connected to a heat sink for power supply and the printer controller changes the rate of print when pre-established temperatures are sent.

摘要： The invention relates to a method in printheads (1) with a plurality of print elements (4) arranged movable in relation to each other and a moving mechanism (7, 9, 11, 12, 14) with magnetic field-responsive forces for moving selectable print elements to print or inactive positions. With utilisation of the method the forces with which selected print elements are moved in appropriate cases to their print positions can be changed in co ordination for a plurality of print elements. In accordance with the invention this is achieved by a magnetic field change co ordinated for several print elements.
The invention also relates to a printhead (1) with a plurality of first electromagnet means (9, L1 L24) for moving selectable print elements (4) and also a second electromagnet means (LB) common to a plurality of print elements, for co ordinated change of the forces for a plurality of print elements with which the print elements can be moved to their print positions.
A method and a printhead in accordance with the invetion are primarily intended for matrix printers.
摘要翻译：本发明涉及一种打印头（1）中的方法，所述打印头具有可相对于彼此移动的多个打印元件（4）和具有用于移动的磁场响应力的移动机构（7,9,11,12,14）可选择的打印元素打印或非活动位置。利用该方法，可以在多个打印元件的配置中改变在适当情况下将选择的打印元素移动到其打印位置的力。根据本发明，这是通过为几个打印元件配置的磁场变化来实现的。本发明还涉及一种打印头（1），其具有用于移动可选择的打印元件（4）的多个第一电磁体装置（9，L1 L24），以及用于多个印刷元件共同的第二电磁体装置（LB）对于打印元件可以移动到其打印位置的多个打印元件的力的协调变化。根据邀请的方法和打印头主要用于矩阵打印机。

摘要： An impact printer with a hammerbank having print hammers retained by a permanent magnet (82) for impacting a print ribbon, and a mechanical driver for moving the hammerbank across print media. First and second coils (98, 100) for each hammer are wrapped around first and second pole pieces (84, 86), one of which is asymmetrical to the other pole piece. One of the pole pieces (84) can have a generally elongated longitudinal form with the coil (98) wound around the longitudinal form. The other (86) can have a generally arcuate form, with the coil (100) wrapped on a portion between the ends thereof. The coil (100) wrapped around the arcuately formed pole piece (86) is thicker than the coil (98) wrapped along the longitudinal pole piece (84). The result is to provide pole pieces and coils for an impact printer having differing spatial relationships that can be staggered, or formed asymmetrically for more compact coil and pole piece placement to improve printer efficiency.

摘要： A machine tool system includes a machine tool and a marking apparatus. The marking apparatus can mark parts-data on workpiece parts at high speed, without occupying any tool mounting station and without having any limitation in the number, the sequence direction, the size and the type font of characters to be marked. A mount base (33) is fixedly attached to a frame (1) of the machine tool. A marking head (51) is mounted on the mount base (37) so as to be movable in the vertical direction. The marking head (51) is provided with a pneumatic stylus (77) movable horizontally both in the X- and Y-axis direction. A parts-data of dot matrix type can be engraved on the workpiece parts by moving the stylus (77) in the X- and Y-axis directions.

摘要： The specification describes a low reluctance magnetic circuit for a dot matrix line printer for retaining hammersprings (16) by the magnetic circuit having pairs of pole pieces (44) formed of magnetically conductive sheets having a space for receipt of a permanent magnet (52). A coil (94,96) is wrapped around a portion of each of the pole pieces (44) between the magnet and the ends to provide a reverse magnetic field to the magnetic field provided by the permanent magnet (52). A magnetic shunt (54) is established between the pole pieces (44) to provide a greater magnetic effect. The pole pieces (44) are sized and plated at the ends, with a spaced wear bar (70) between them to provide improved performance and longer wear.
