Title: Automatic internal calibration circuit and method
Inventor: HARTWIG ROBERT W
IPC: G01N33/00
Filed: 1991-10-11
Abstract: Apparatus for calibrating the gas detector of a gas analyzer includes a gas source circuit for providing a standard sample gas at a substantially constant, predetermined pressure. The gas source circuit includes a gas bottle for containing the standard sample gas and a pressure regulator circuit for maintaining the output pressure of the gas source circit to the substantially constant, predetermined pressure. Ideally, the gas source circuit is semipermanently coupled to the gas detector so that calibration may be performed at any time, even while the gas detector is coupled in an analysis circuit for analyzing an unidentified sample gas. The gas analyzer further includes a data processor that responds to programming instructions and data for controlling the gas source circuit and gas detector to perform the zero measurement and span measurement needed for calibration. The data processor is constructed to initiate a calibration operation upon the occurrence of a predetermined event such as, for example, elapse of a predetermined time interval.

Title: Video switcher apparatus for wide screen edtv signals
Inventor: SUGIMORI YOSHIO
IPC: H04N7/015
Filed: 1992-07-23
Abstract: ABSTRACT    A compatible special effect signal can be produced without using an encoder or a special signal processor.  Each of EDTV signals is divided into a main screen signal and a compensation screen signal.  Compensation screen modification circuits modify the special position and size of the compensation screen signals such that the compensation screen signals match with the main screen signals in special Position and size.  The modified signals and the main screen signals are multiplexed in a frequency domain.  The multiplexed signals are gated in response to a wipe signal and the gated signals are mixed with each other.          The mixed signal is separated into the main screen signal and the compensation screen signal in the frequency domain.  A compensation screen signal restorer circuit converts the frequency separated compensation screen signal into the original compensation signal which is mixed with the main screen signal to generate the wiped wide screen EDTV signal.

IPC: H04L29/08
Filed: 1993-04-20
Abstract: First and second data processing terminals (12, 28) are coupled together via at least one modem (36). A stream of data is supplied to the modem, which has a data transfer mode and a command mode while that modem is operating in the data transfer mode in a first communication session. A preselected escape character followed by a selected command sequence is inserted into the data stream and is detected and utilized by the modem to automatically initiate a second communication session by specifying the network, node, application, service level and the like for the second communication session. Thereafter, selected data within the data stream may be preceded by the preselected escape character and a session identification command sequence and thereby accurately identified as associated with a particular communication session, without requiring the data processing terminal application to have knowledge of data packet protocols and formats. <IMAGE>

Title: Method and system for retrieving ideographic characters and the associated dictionary entries
Inventor: WOO EDWARD P H
IPC: G06F17/27
Filed: 1993-06-08
Abstract: METHOD AND SYSTEM FOR RETRIEVING IDEOGRAPHIC CHARACTERS AND THE ASSOCIATED DICTIONARY ENTRIES                 ABSTRACT OF THE DISCLOSURE                A method and system for retrieving ideographic characters such as Chinese characters wherein a computer displays a set of four questions relating, respectively, to the geometrical characteristics of the first and last strokes and any geometrical enclosures of the character to be searched and its total number of strokes.  The computer also displays a fifth optional question relating to the number of crosses each formed by two strokes in the character.  The user selects among the various choices for the character.  Upon each selection by the user, the computer conducts a search eliminating characters that do not correspond to the characteristic description selected.  After the search is completed, the computer displays all characters having the selected characteristics and a total number of strokes within a predetermined range of that entered by the user to accommodate for possible counting errors.  If too many characters are displayed, the user may enter the answer for the fifth optional question.  In that case, the computer conducts a further search to eliminate those that do not meet the description and display those that do.  Thus, only fewer characters are displayed for efficient identification by the user.  The computer then displays the corresponding pronunciation and explanation entries for the character like any conventional dictionaries.            HTT\15468-2.PA2

Title: Method for Manufacturing Glass Bottles
Inventor: NAKAGAWA MANABU
IPC: C03B35/06
Filed: 1993-06-15
Abstract: The problem of unevenness of bottle temperatures at the entry of slow annealing furnace due to the variation of time periods necessary for respective bottles discharged from an IS bottle manufacturing machine to reach the annealing furnace has been solved by an equalization of said time periods. For this purpose, the bottle discharging order from the IS bottle manufacturing machine is controlled and use is made of two conveyors having different running speeds and/or direction of running. As a result, a precise temperature control in the Hot-End-Coating apparatus provided upstream from the annealing furnace can be carried out owing to the equalized temperatures of bottles entering into the annealing furnace.
