摘要： A tape drive that includes a capstan and tachometer mounted on the same shaft with a printed circuit motor. The capstan and tachometer are mounted to be accurately concentric with one another and the tachometer is sensed at the same angular position as the point of tangential engagement of tape and capstan and at the same radius, and controls the peripheral velocity of the capstan there so that even though the capstan may be eccentric relative to the true motor turning center, the tape speed is constant. The armature disc of the motor is accurately mounted in a plane normal to the shaft, and upon a cushioning element, to reduce brush contact errors.

摘要： A thin film structure is fabricated using photolithographic techniques and includes a plurality of substrates defining a resistor film, a conductor film and a passivation layer. The resistor film is etched to provide a plurality of individual heaters. The conductor film is etched to provide a plurality of conductive traces. At least one passivation layer covers the conductor film. A plurality of electrical contact pads are also formed that extend through etched holes in the passivation layer so that the electrical contact pads make electrical contact with the conductive traces. A nozzle plate is attached to the thin film structure. The nozzle plate has a plurality of individual nozzle orifices and also defines a plurality of corresponding ejection cavities for receiving ink from an ink reservoir via capillary action. The ejection cavities are each aligned with a corresponding one of the heaters for thermally ejecting ink through the orifices onto an adjacent print medium, The thin film structure and the attached nozzle plate are mounted to a housing that includes the ink reservoir. A mixture of a volatile liquid carrier and at least one corrosion inhibitor is sprayed onto the portion of the thin film structure having the plurality of electrical contact pads. The mixture has a very low surface tension so that the mixture will wick into any minute crevices around the perimeters of the electrical contact pads. The liquid carrier is evaporated by passing the assembled print cartridge through an oven so that the corrosion inhibitor will hermetically seal the crevices. Moisture is thereby prevented from entering the minute crevices and causing corrosion that would otherwise lead to operational failures of the print cartridge.

摘要： A disk drive having a base and a cover, enclosing the memory disks and the magnetic head actuator. The spindle journaling the memory disks and the support for the actuator are secured to the base and to the cover and relatively position the base and the cover with respective peripheral extremities in closely spaced, but not touching relationship, to provide a gap therebetween. A pressure sensitive adhesive tape of a material having a high shear strength is applied to the base and the cover bridging the gap without applying stresses to the cover or the base through the tape and providing a seal for the disk drive between the cover and the base. The materials of the base, the cover, the spindle and the support, have thermal coefficients of expansion which are at least substantially the same. Preferably the materials are the same. Steel is a preferred material. The design also provides rigidity between the ends of the rotary mounting of the memory disks and the support for the magnetic head actuator while providing flexibility in the connections between the base and cover, and thereby eliminating thermally induced slip at these connections. Slip between structural parts of a disk drive can prevent reliable writing and reading of data.

摘要： A replaceable ink container for providing ink to a printhead of a printing system. The ink container has a housing that includes and ink reservoir for containing a supply of ink, and an ink level sensor for sensing a low ink condition in the ink reservoir. The ink reservoir includes a capillary ink storage member. The ink level sensor includes resistance probes that are in fluid communication with the supply of ink, but are free from contact with the capillary ink storage member. The resistance probes are mounted to the housing by way of sensor ports that extend through the housing and prevent contact between the capillary ink storage member and the probes. The resistance probes protrude slightly from an exterior surface of the housing to define electrical contacts for engaging corresponding electrical contacts of the printing system. A change in electrical resistance measured across the resistance probes indicates a low ink condition in the ink reservoir.

摘要： A disk drive in which the base and the cover are interconnected in spaced positions to provide a marginal, peripheral gap between confronting or adjacent faces or edges thereof. The gap is bridged, closed and sealed by means of a pressure sensitive adhesive tape, a viscoelastic tape, which is energy adsorbing to damp disk drive vibrations.

摘要： In order to improve servo system stability and decrease settling times in rotary head positioners for high performance magnetic disc drives, a floating mass damper is mounted on the end of an accessing head arm structure of the positioner opposite to the end or ends carrying the magnetic head or heads. The damper includes a centered floating mass which rests on a viscous film, such as silicone oil, and the shear forces developed by motion of the floating mass across the film dissipates vibrational mode energy in the accessing head arm structure during both a fast seek operation followed by track following fine servo operation. Such energy dissipation thus reduces the settling time and amplitude of natural resonance of the head positioner.The floating mass may be either an elongated cylindrical metal slug or a plurality of steel balls, but lower tolerances and lower manufacturing costs are made possible when the steel balls are used as the floating mass.
