Abstract: An inkjet nozzle arrangement includes a substrate that defines an ink supply channel. Integrated circuitry is positioned on the substrate. An ink chamber structure is positioned on the substrate and defines an ink chamber in fluid communication with the ink supply channel and an ink ejection port in fluid communication with the ink chamber. A paddle is positioned in the ink chamber and is movable to eject ink from the ink ejection port. The paddle has a generally concave cross section with respect to the ink ejection port. An actuator is connected to the integrated circuitry and is operable on the paddle to displace the paddle.

Abstract: A fluid ejecting printhead including a substrate having a surface, and a columnar group of drop generators formed on the surface that are arranged into subgroups, each subgroup being fluidically isolated from other subgroups on the surface. Firing pulses are provided to the drop generators such that no two drop generators in the same subgroup are activated in sequence.

Abstract: In an inkjet printhead, a substantially rectangular heater element has a length and width dimension defining an aspect ratio of more than about 2.0. A bubble chamber with a curved or convex wall portion partially surrounds the heater element. A radius of an arc defining the convex wall portion is greater than one-half the width dimension while less than one-half the length dimension and none of the convex wall portion overlies a periphery of the heater element. An ink ejection orifice exists through a thickness of a nozzle plate covering the bubble chamber and resides above the heater element. Additionally, the bubble chamber may have a rectangular wall portion connected to the convex wall portion and either portion may occupy a terminal end of the bubble chamber. Preferred length and width dimensions include 35 and 13 or 40 and 10 microns with a radius of about 16 microns.

Abstract: In a light-guide plate for use in a liquid crystal display device, light enters a transmissive plate member from one end face thereof, is reflected and diffused inside the plate member, and emerges from one main surface of the plate member. A guide member is formed integrally with the main surface so as to guide a light-diffusing sheet member to be placed thereon.

Abstract: A multi-channel recording device for recording the time profiles of a plurality of measurement signals which can be connected to the device. The device has first and second groups of optical indicators on the front of the device and scale strips corresponding to the physical variables to be measured. There are n indicators in the first group, m indicators in the second group and scale strips where n is greater than m. The device assigns one and only one of the m indicators to each of the n indicators.

Abstract: A fiberoptic/electronic intubating scope with camera and lightweight portable screen is used for the intubation of the trachea (or other body cavities and lumina) in patients where structures such as laryngeal and tracheal structures are not easily viewed directly using standard devices such as a standard laryngoscope and blade because of anatomic or morphologic irregularities or changes.

Abstract: Data is recorded with a plurality of clocked recording elements in a plurality of recordings in a plurality of different scales determined by different data recording parameters. Data recording parameters for any scale are electronically fixed for each recording in that scale, and are stored in a lookup table. Such stored data recording parameters are derived from that lookup table for determining the clocked recording elements for data recording in the particular scale, and data is recorded with such determined clocked recording elements in that scale.

Abstract: The driving frequency of a head is changed in conformity with temperature, and density data is converted into an optimum head driving voltage in conformity with temperature, whereby the discharge driving frequency and driving voltage of the recording head become optimum under any temperature condition, and thus recording of high quality is ensured the since irregularities caused by the temperature variation of the recording head are eliminated. The driving voltage is set by a drive control circuit that includes a plurality of limiters, one of which is chosen in accordance with ambient temperature.

Abstract: An electronic apparatus includes a printer for graph printing, in which the vertical and horizontal dimensions of the printed graph can be modified by a device for modifying the scales of the graph.

Abstract: A curve plotter or a display device for the recording of a curve section outside of a recording field is equipped with a logic circuit which shifts it into the recording field. Either the curve recording is continued after a margin of the recording field has been reached in the inverse recording direction, or the original recording direction is maintained but the curve recording is continued from the opposite margin of the recording field. Recording of the off-scale curve section can be performed by digital or analog steps and can be marked specifically.

Abstract: In an exemplary embodiment, a recording head and recording carrier are movable relative to one another for the purpose of recording several measurement signals on the recording carrier. It is the object of the disclosure to produce such a recording device which, with the lowest possible technical outlay, offers an optimum variation possiblity in the recording of a plurality of individual signals. This object is achieved in accordance with the disclosure by virtue of the fact that there is allocated, to an individual recording head as the recording element on the recording carrier, a variable number; e.g.

Abstract: In a potentiometric chart recorder, the speed of the chart motor 22 is, in one mode of operation (AUTO) selected by a switch 32, varied between two values in dependence upon the rate of change or slope of the input signal at 10 as detected in a detector 30. The slow speed is obtained by intermittent operation at the fast speed, and during the non-operative periods power-consuming circuitry e.g. 16, 18, 26 is switched off by a switch 40.

Abstract: An instrument for recordation and time monitoring of pressure, as at a remote wellhead site. The instrument is battery powered, and means for conservation of battery power include powering the device intermittently under control of low power-drain CMOS clock timing circuits. Relatively higher power-drain calibration and display modes are continuously powered only on operator demand. In any operating mode, only those elements necessary to effect the mode are powered, either on an intermittent or continuous basis, as appropriate to realize the mode objective.

Abstract: A variable chart format system for a recorder with a chart print out, the system having a manually selectable switch for simultaneously controlling the abscissa and ordinate formatting independent of scale expansion circuitry normally associated with the abscissa and ordinate. The abscissa formatting is digital and operable in response to a programmable or variable clock, the output of which is selectively passed through a first set of abscissa formatting frequency dividers and then serially through one of a second set of abscissa scale expansion frequency dividers to drive a chart drive stepper motor.
