Patent number: 4853715Abstract: A pen plotter employs a cable-driven carriage which carries the writing pen and includes a pen-lift mechanism. A shifting idler pulley system located at one side of the plotter returns a pair of drive cables from the opposite side of the carriage to a rotatable drive drum located on the opposite side. The idler pulleys are shiftable equally and in opposite directions toward and away from the pen carriage. One cable is connected to the carriage by being tensively trained about a pen-lift mechanism drive wheel on the carriage. Shifting the idler pulleys causes said drive wheel to rotate without affecting the lateral position of the pen carriage and, therefore, the shifter mechanism independently controls the up/down motion of the writing pen. One drive cable, therefore, accomplishes the functions of both pen carriage movement and writing pen up/down motion control.Type: GrantFiled: June 17, 1988Date of Patent: August 1, 1989Assignee: Numonics CorporationInventor: Albert E. Paschkis

Patent number: 4849771Abstract: An improvement to graphics pen plotters including a pen gripping mechanism for gripping a cylindrical bodied pen in a generally vertical orientation for sensing the presence and type of a pen in the gripping mechanism with a single sensor. There is a multi-channel sensor adapted for producing and sensing a plurality, "n+1", of parallel light beams disposed one above the other to produce a binary number at an output thereof indicating the ones of the light beams sensed by the sensor. The sensor is disposed to shine the light beams at a position past which the pen is moved by the gripping mechanism.

Patent number: 4847630Abstract: We describe an integrated thermal ink jet printhead and manufacturing process therefor which includes the successive build-up of an orifice plate, a first barrier layer, heater resistors, a second barrier layer, and an ink reservoir-defining layer on top of a reusable or "dummy" substrate. Lead-in conductors are formed integral with the heater resistors by controlling the cross-sectional areas of these components, and openings (passageways) are formed between ink reservoirs and the orifice plate to provide for ink flow under control of the heater resistors. The dummy substrate is stripped away from the adjacent orifice plate, and the ink reservoir defining layer may be secured to an ink supply tank which supplies ink to the individual ink reservoirs. Thus, the orifice plate, heater resistors and ink flow paths of the printhead are self aligned, and the heater resistors are removed from direct cavitational forces from ink ejected from the orifice plate.Type: GrantFiled: December 17, 1987Date of Patent: July 11, 1989Assignee: Hewlett-Packard CompanyInventors: Eldurkar V. Bhaskar, Marzio A. Leban
