    摘要: A magnetic memory system having a recording head adjacent a movable disk is described wherein the recording head is separated from the disk by a fluid bearing. In a preferred embodiment, the bearing comprises a taper land bearing having a main bearing face preceded by a converging bearing face. A narrow slot provides a hydrodynamic separation between the trailing edge of the main face and the leading edge of a satellite face coplanar with the main bearing face. A diverging face is provided aft of the satellite face. In operation the recording head is retracted until the disk is up to its usual rotational speed, and then the head is advanced toward the disk to its final floating position in the order of 30 microinches from the surface. The satellite face and diverging face cooperate during the transitional ''''landing'''' of the recording head to produce a fluid film force that pivots the recording head to its final floating position without contact between the disk and head.

    摘要: A ribbon feeding apparatus having a ratcheted ribbon spool engageable by a reciprocating pawl to incrementally rotate the ribbon spool. A camming lug operatively coupling the pawl and responsive to the diameter of the ribbon on the spool inversely varies the increment of angular engagement of the pawl with the ratchet wheel as the ribbon diameter increases, thus effecting uniform ribbon feed.

    摘要: A semiautomatic machine for simultaneously bending the leading and trailing edges of a lithographic printing plate. The plate bender has a ruggedly constructed frame which supports and guides a vertically movable plate supporting bed. The bed has a fixed anvil with a pair of spaced locating pins and an anvil which is movable relative to the fixed anvil to adapt the bender to bend different size printing plates. A fixed and movable pressure block are supported a short distance above the fixed and movable anvils, respectively. Each of the pressure blocks has a spring biased vertically movable gripping face and a cam operated horizontally movable forming block. An adapter is also provided to enable the bender to shape lithographic plates smaller than the adjustable range of the bender. In operation, a prepunched lithographic printing plate is positioned on the locating pins. The plate supporting bed is then driven vertically by a pneumatic cylinder to bring the plate and anvils into engagement with the pressure blocks. The bed continues to rise causing the pressure blocks to firmly grip the printing plate and to rise against the downward biasing force. As the pressure blocks move a camming slot at each end of the blocks acts upon a cam follower within the slot causing it to move in a horizontal direction relative to the pressure block. The cam followers draw the forming blocks inward toward the printing plate causing the leading and trailing edges of the plate to simultaneously bend inward against forming faces on the anvils. After the plate is bent the bed is lowered allowing the operator to slide the formed plate off of the anvils.

    摘要: A tape handler is provided having a drive coupling mechanism, a part thereof being axially translatable in response to an end-oftape condition. The handler includes a pivotally mounted carrier forming a pocket to receive and retain a tape cassette, the carrier being releasably secured to the body of the handler, the translatable part having the function of initiating both the release of the cassette and of the carrier, the latter resulting in a separation of the carrier from the handler body sufficient to uncouple tape drive.

    摘要: A method for quickly making an intaglio or gravure printing plate through the use of near infrared irradiation. A pattern of protuberances or grooves is formed on a surface of near infrared transparent, moldable plastic, glass, or quartz which is not deformable at the temperature used in practicing the invention. This gravure matrix can be in the form of a sheet, endless belt, or plate. The information to be reproduced can be printed, written, or drawn in highly near infrared absorbing material on a copy sheet, which can be of paper, for example, or other substantially infrared transparent or reflective material. The copy sheet is assembled with the infrared absorbing material in contact with a base plate sheet of transparent, unoriented, near infrared non-absorbing plastic, which in turn is placed on the gravure matrix. Under uniform pressure of 5 to 50 p.s.i. the assembly is exposed briefly to near infrared energy. The base plate sheet will have formed therein an exact reproduction of the copy material in the form of a multiplicity of cells or grooves. This gravure printing plate can then be mounted according to known procedures on an offset gravure printing device.

    摘要: An integrated circuit driver system utilizing Metal-OxideSilicon Field-Effect Transistors (MOS FET''s) is disclosed for operation in a two-phase mode for driving a substantially capacitive load. A preferred embodiment of the invention makes use of an alternating current (ac) voltage having a peak-to-peak magnitude somewhat greater than the direct current (dc) supply potential. An auxilliary dc power supply is implemented for converting the ac voltage to an operating potential for inverters which in turn provide the phase inverted signals required by a pair of drivers. The latter generate the alternate phases of the output voltage presented to the load. Additionally, the system exploits the MOS threshold voltage dropping properties to realize a threshold shift of suitable magnitude to insure the required duty cycle of the driver output pulse waveforms.

    摘要: A hand tool is described for removing integrated circuit components or the like from printed circuit boards. The tool has a plierlike action for bringing a pair of heated jaws each provided with a flat electric resistance heater against the component leads for melting the solder attaching the component to the board. An adjustable stop prevents the heated jaws from contact and damaging the board. A pair of pincer jaws are mounted on one of the heated jaws so as to be movable in a direction transverse to the direction of movement of the heated jaws. Cams on the pincer jaws are actuated by the other heated jaw to close the pincer jaw in response to closure of the heated jaws. The pincer jaws have a turned end for gripping beneath a component for lifting the component after the solder is melted.

    摘要: A high-speed serial printer including a continuously rotating print drum having characters on its periphery, a hammer and carrier, and a belt for transporting the hammer and carrier parallel to the axis of drum along a line of print. A control system, including two timing discs, operates in synchronism with the drum. The first disc is indicative of the angular position of the drum and the second disc is to signal the hammer carrier to engage the transport belt at the start of each line of print. A double-ended transducer responds to the two timing discs to provide the appropriate signals for the printer.
