Abstract: In a driving method of a plasma display device, a final voltage of a falling ramp voltage is set to a discharge firing voltage of all the discharge cells after applying a gradually rising ramp voltage during a reset period. A difference in voltage applied to an address electrode and to a scan electrode is set to be greater than the maximum discharge firing voltage in turn-on discharge cells in an address period. A bias voltage applied in a rising reset period, an address period, and a sustain period of subfields that express low grayscales is increased, and the address electrode is biased with a positive voltage in the sustain period. With this configuration, the problem of worsening the margins by loss of wall charges is solved since addressing is not influenced by the wall charges and performance of expressing low grayscales is increased.

Abstract: An improved monitoring system which identifies the particular event (contact operation) and therefore the particular electromechanical relay (20, 22, and 24 which operated). This information is output from a MCU (30), along with the relative time the event occurred, to a PC and an LCD display (40). In addition, the relative occurrence time is recorded to the thousandths of a second.

Abstract: In a recording apparatus, a laser beam with the pulse modulated corresponding to image data scans an objective plane by a deflection device. On that occasion, a plurality of select signals are generated corresponding to the position of the laser beam on the scanning line based on the start signal indicating the start of scanning by the laser beam. The generated reference pulse is frequency-divided to form a plurality of pulse signals having a different width. One of the pulse signals is selected by the select signal and the image data is processed based on the selected pulse signal. The select signal is set to make a wide pulse signal correspond to the central portion of the scanning line and a narrow pulse signal correspond to both end portions of the scanning line.

Abstract: The disclosed tachograph writes work data for motor vehicle work into a microprocessor-controlled EEPROM semiconductor memory mounted on a movable data card carried by the driver. A printing device prints out the content of a data card memory in the form of a tabular drive record in plain language. The face of the tachograph includes receiving slots located next to one another for the data cards of a driver and a co-driver, as well as a line display for guiding the driver as to how to key in information. A front slot in the face of the tachograph receives an unimprinted paper sheet. Two keys enter the work times, while the functions concerning the print-out of the driving record are controllable with a keyboard on the basis of information on the line display.

Abstract: Apparatus for printing alpha-numeric characters for plotting an incoming signal at rates on the order of one page every seven seconds for rapidly verifying that the system producing the incoming signal is operating properly. Both printing and plotting are done by styli mounted on a moving carriage and individually electrified to produce marks on a specially prepared paper. The stylii are moved back and forth across the paper, marking in both directions. The carriage is not stepped across the page, but instead is moved smoothly from one side to the other side under control of a velocity servo. A controller generates and applies velocity command inputs to the servo, based on the position of the carriage as sensed by an optical encoder, and based on certain characteristics of the incoming signal. A first buffer memory accumulates the incoming signal until a line has been stored for plotting, while a second buffer memory is applying its accumulated contents to the printhead.

Abstract: A printer system is associated with a taximeter for calculating the taxi fare, a seat switch for detecting a passenger who occupies the taxi, and a timepiece. A printer driver functions to drive the printer to record a drive condition of a taxi and time information each time when the drive condition is changed, for example, from "for hire" wherein the taxi is not occupied by the passenger and no fare is computed to "occupied" wherein the taxi is occupied by the passenger and the taxi fare is computed through the use of a predetermined tariff.

Abstract: A code generator generates, upon command, code sequences representing either time of day, time and date, or event number codes, in either single sequences or continuously repeating code sequences for simultaneous recordation with a physiological event on magnetic tape or oscillographic paper for permanently identifying and indexing biomedical data. Multiplexed binary coded decimal output lines of a digital clock are strobed to provide the option of either single frame or continuous frame operation while requiring no critical timing circuits, and the sequencing operations are synchronized by the multiplex timer, which recordation is visually interpretable.
