Abstract: Apparatus and accompanying methods are disclosed herein for use in a Coriolis mass flow rate meter for producing an "absolute" frequency output. This method is illustratively implemented within a microcontroller through use of Various software steps, two internal timers and one external gate. The frequency signal present on this output advantageously contains a number of pulses having an approximate 50% duty cycle over a relatively wide dynamic range wherein the number of such pulses occurring during any timing interval is proportional to the measured mass flow rate but without substantially any extraneous pulses that would otherwise occur due to nested interrupt processing. As such, use of such a frequency output advantageously ensures that internally and externally maintained totalized mass flow values will not substantially diverge, if at all, over time.

Abstract: The connection and shielding system for modular RF circuits encases modular circuitboards (10) within five-sided enclosures (11). The sixth side of each enclosure is provided by the top ground plane of a base circuitboard (20) that supports and electrically interconnects the components of the modular circuitboards (10). Enclosures (11) are fixed to a grounded metal socket formed by fence strips (22) and metal inserts (23) which form upwardly open slots including yieldable longitudinal gaskets (50). Gaskets (50) yieldably grip the open end of enclosures (11) and seal them against escaping radiation. Further radiation shielding is provided about the base circuitboard (20) by the fact that the conductive signal traces provided in it are sandwiched between two continuous ground planes and run between plated-through vias joining the ground planes. The ends of each enclosure are provided with double wall baffles (17, 18) which provide airflow to the interior and RFI shielding through offset open apertures (13).

Abstract: An apparatus (18) which develops an electrostatic latent image recorded on a photoconductive member (10) used in an electrophotographic printing machine. The apparatus employs a developer material (64) which ages during the life of the electrophotographic printing machine. Carrier granules are added (68) to the developer material to extend the life of the developer material. When the quantity of developer material exceeds a predetermined quantity, developer material exits therefrom through an exit port (74). A magnetic flux field is generated (78) in the region of the exit port to form a carrier bead curtain which prevents the passage of toner particles therethrough while permitting developer material and carrier granules to exit therefrom.

Abstract: A method is disclosed for defining the structure of a document by specifying the relationships between document elements in a data stream. A plurality of tabu­lar specifications are provided, each of which includes a number of document elements. The logical relationship between each document element and all other document elements within each tabular specification is specified once for the entire tabular specification. The semantic interpretation for each tabular specification is associat­ed with a named reference to that tabular specification so that multiple references to that tabular specification may yield different semantic interpretations. In this manner, it is possible to minimize the amount of specification to define a document by utilizing individual tabular specifi­cations repeatedly. Additionally, a reference to a tabular specification may be utilized to modify the existing logical relationship between the document elements con­tained therein. In a preferred embodiment of the present invention, a range of allowable values for individual document elements within a tabular specification may be specified by the user.

Abstract: A method is disclosed for controlling the monitoring of telephone status changes by an associated processor. A status change inquiry message is transmitted from the associated processor to the telephone and is utilized to set an interrupt mode within the telephone (42). The status change inquiry message may also include a timer setting value (48) which is utilized, in a preferred embodiment of the present invention, to determine a maximum duration for the interrupt mode. In response to a change in telephone status (52), or the termination of the timed interrupt mode (54), a single phone status message (56) is sent to the associated processor and the interrupt mode is terminated. In this manner, a change in phone status may be determined by the associated processor without the necessity of continuously polling the tele­phone. Further, any transmission of a phone status change terminates the interrupt mode and prohibits the telephone from continuously interrupting the associated processor with status change messages.

A feed reel (21a) of a C-cassette (compact cassette) (21) is mounted directly on the feed reel table (13), while a take-up reel (21d) of the C-cassette (21) receives a driving force transmitted from the take-up reel table (14) through a torque transmitting mechanism (23). The full-size cassette (12) is driven directly by the feed and take-up reel tables (13, 14) in the state wherein the tape (12c) is loaded by a tape loading member (28, 29), so that a tape (12c) of the fu|1-size cassette (12) is run. On the other hand, in the state wherein a tape (21c) in the C-cassette (21) is loaded by the tape loading member (28, 29), the C-cassette (21) is driven such that the feed reel (21a) of the C-cassette (21) is rotated by the feed reel table (13) while the take-up reel (21d) of the C-cassette (21) receives a driving force from the take-up reel table 14 through the torque transmitting mechanism (23). Thus, the tape (21c) in the C-cassette (21) is run.

Abstract: An insulating substrate (101) has a U-shaped conductive layer (108) which produces a magnetic field (121) when a current flows therethrough as indicated by arrows (120). The substrate (101) also includes a conductive layer (103) on which a power semiconductor element (102) is mounted through its main electrode. A current detector (111) such as Hall effect elements is located inside the U-shaped conductive layer (108). When a load current flows through the semiconductor element (102), it flows through the conductive layer (108) to produce the magnetic field (121) since the other main electrode of the semiconductor element (102) is electrically connected to one end of the conductive layer (108) through a metal wire. Accordingly, the load current flowing through the semiconductor element (102) will be effectively detected by the current detector (111) without connecting a resistor or current trans­former to external terminals of a power semiconductor device, thereby providing a composite semiconductor device with a compact structure used for inverters for driving three-phase motors, etc.
