A dual-shaft synchronous movement device and an assembling method thereof. The dual-shaft synchronous movement device includes a first shaft and a second shaft, which are assembled with each other and synchronously rotatable. The invention includes providing an assembling device and arranging on the assembling device a first rotor and a second rotor (or a third rotor and a fourth rotor) between which a drive section is wound; winding the drive section onto the first and second rotors (or the third and fourth rotors) in a tensioned state; and pushing the first and second rotors (or the third and fourth rotors) onto the first and second shafts. Through the first and second rotors (or the third and fourth rotors) and the drive section, when the first shaft is rotated, the second shaft is synchronously rotated.

A dual-shaft synchronous motion device includes a first shaft and a second shaft; a first rotor disposed on the first shaft and turned synchronously; a second rotor disposed on the second shaft and turned synchronously; and a tractive member disposed between the first rotor and the second rotor. When the first shaft drives the first rotor to turn, the tractive member brings the second rotor to turn reversely relative to the first rotor so that the first and second shafts are turned synchronously.

The invention relates to a frictionless self-driven articulation designed to be mounted between two neighboring elements (E1, E2), comprising two cylindrical fittings (12, 14) rotationally driven through the action of at least one flexible element, of the leaf spring type, the ends of this element being fixed respectively to each of the fittings. According to the invention, the articulation includes means of retaining the fittings (16, 28; 42, 44) and load transfer means (61, 62; 50) separate from the retention means.

One or more coupling assemblies are located at each opposite end of a first part and a second part. Each coupling assembly includes an elongated slot formed in the first part and a corresponding latch device which projects from the second part and which is releasably receivable by the slot. The latch device includes a tab and a pair of spaced-apart fingers projecting from the second part. The tab is positioned between the fingers. The fingers project generally linearly and parallel with respect to each other, and define a plane. The tab has a base, a first leg and a second leg. The base extends generally parallel to the fingers. The first leg extends away from the plane and from a first end joined to the base to a second end joined to the second leg. The second leg and extends towards the plane and away from the second end of the first leg. The first and second legs form an apex which is spaced apart from the plane of the fingers. The first part forms a pair of ramp surfaces adjacent to the ends of each slot. The ramp surfaces engage the fingers to help guide the latch device into the slot. The second leg engages an edge of the slot when the latch device is being inserted into the slot, and the tab deflects towards the plane as the latch device is inserted into the slot. The fingers engage the end walls of the slot and deflect towards each as the latch device is inserted into the slot. The first leg engages an edge of the slot when the latch device is fully received by the slot, and the tab is biased to urge the latch device into the slot.

A thermal demand printer for printing on media is a novel system which includes a case structure including a hinged cover panel, easily removable guide structures and media hanger, and a single central support wall to which the various components are attached. The printer includes a power supply circuit for receiving power from an external source and conditioning it for operation of the printer. An input device is provided for receiving command signals related to the operation of the printer. A control circuit for processing the command signals and generating corresponding control signals for controlling the operation of the printer and a printhead assembly for processing the control signals and generating corresponding control signals for controlling the operation of the printer are mounted in the case structure and coupled to the input device and the power supply circuit. The printhead assembly includes a printhead support structure which controls the printhead. A ribbon take-up spindle, method of operating the take-up spindle using a PMDC motor, and a spring wrap clutch device help to control the tension in the transfer ribbon used in the printer. The printer also includes a medial sensor and a method of sensing media by way of detecting the opacity of the media passing through the sensor. The printer includes a method of printhead control using double data loading and a method of accelerating and decelerating media relative to the printhead using pulse width modulation.

A spring hinge between panels of a satellite panel array comprises a plurality of serially joined known flexural pivots of the type having two cylindrical members with tongues from each extending into the other joined by a flat spring. One panel has an abutment for limiting the rotation of the next panel with respect thereto such that the spring hinge remains partially stressed when the panels are deployed. In another embodiment, two pluralities of serially joined pivots act in parallel.
