Abstract: An inner lid (16) is attached to a vacuum chamber (11), covering an inner region (10) of the vacuum chamber. An outer lid (12), also attached to the vacuum chamber, covers the inner lid (16), leaving a region (20) between the inner lid (16) and the outer lid (12). A gas conduit (22) allows gas to flow between the inner region of the vacuum chamber (10) and the region (20) between the inner lid (16) and the outer lid (12). A filter (21) is placed in or immediately outside the gas conduit (22) to prevent particles from entering the inner region (10) of the vacuum chamber from the region (20) between the inner lid and the outer lid. Since the pressure is the same on the top and bottom of the inner lid (16), the inner lid does not flex and thus does not rub against the vacuum chamber (11) when the vacuum chamber (11) is pumped down or vented up.

Abstract: A method for controlling a control apparatus such as a programmable controller which includes a CPU and special function modules. The CPU conducts sequence control and the special function modules perform control other than sequence control in accordance with commands from the CPU. Each instruction represents a normal or special instruction. Special instructions include a first symbol denoting a special function unit-corresponding instruction and a second symbol denotes a special function type (independent of memory addresses). Once the CPU identifies a special function instruction by identifying the first symbol, the CPU stores the contents of the instruction step into a mulit-directional access memory of the special function unit. Thereafter, in one embodiment, the CPU generates an interrupt requesting the special function unit to execute this instruction. In other embodiments, the CPU performs instruction processing to ensure, for example, that the instruction is a correct one for the selected special function module. The special function unit decodes and executes the instruction based upon the second symbol denoting the special function type.

Abstract: An apparatus for producing items in selected configurations and a system and method for controlling the same. More particularly, an apparatus for producing mail pieces and a system and method for controlling it to produce mail pieces in a variety of configurations are disclosed. The apparatus includes a laser printer and folding sealing apparatus controlled by a data processor. The folder sealer apparatus combines sheets printed by the laser printer with pre-printed sheets and envelope forms, which also may be printed by the laser printer or may be windowed envelopes, folds the sheets as necessary and folds and seals the envelope form about the folded sheets to produce a mail piece. A user inputs a configuration for the mail piece which is translated by the data processor into a data structure and transmitted to the controller of the folder sealer apparatus. The controller controls devices comprised in the laser printer and the folder sealer by executing state routines in accordance with the data structure to produce the mail piece in the defined configuration. Concurrently the data processor transmits text from an output file to the laser printer for printing on printed sheets and envelope forms. The data processor also controls the laser printer to print an address for the mail piece either on an envelope form or on a printed sheet in a position where it will be visible through the envelope. Thus the apparatus is controlled to process an output file stored in the data processor into a mail run having a selected configuration.

Abstract: A variable frequency RF passband filter (22) is calibrated to maximize the sensitivity of a radio receiver using reference frequencies applied based on the clock operation of a digital processor within the receiver. The reference frequency passing through the variable passband filter is mixed to the intermediate frequency of the receiver by a mixer (23) and its level is detected. A frequency counter (40) verifies that a measureable reference frequency signal has in fact been mixed to the intermediate frequency in order to avoid errors. The correct control voltage signal for the variable passband filter (22) corresponding to each receiver frequency can thus be conveniently and inexpensively determined and stored for use during normal operation of the receiver.

Abstract: The device is used for simultaneous bidirectional transmission of information which originates from two information sources (11, 12) and is intended for two information sinks (21, 22). For this purpose, a single optical fibre (15), two transmitters (31, 32), two receivers (51, 52) and two directional couplers (17, 18) inserted into the fibre (15) are provided. In one transmitter (31), a laser (34) is located which can be directly modulated and in the other transmitter (32) a reflector (44) is located which forms an outgoing beam (R) from the incoming light beam (V) by reflection. The laser (34) is modulated in such a manner that intensity modulation of the beam V forms a carrier onto which the information signal is modulated by frequency or phase modulation. The second transmitter (32) modulates the beam R in direct intensity modulation.   A filter (56) which blocks the frequency band of the carrier is used in the second receiver (52) to improve the signal-to-noise ratio. This filter can be constructed as a simple electrical low-pass filter. <IMAGE>

Abstract: A circuit and method for controlling an output current balance for parallel driven PWM-type digitalized power inverting units are disclosed in which a feedback control such that rising edge times and falling edge times of a PWM waveformed pulse train signal to be supplied to the parallel driven power inverting units are respectively corrected using independent correction signals is carried out to eliminate a deviation between output currents of the parallel driven power inverting units. The correction of the rising edge times and falling edge times is such that a phase advance correction for the one unit with respect to an offset value delay and a phase retardation correction for the other unit with respect to the offset value delay are carried out so that a delay of an average output current with respect to the PWM waveformed pulse train signal is made constant. In addition, if an integration calculation of the feedback control is carried out during a constant period of time upon a change in the PWM waveformed pulse train signal to suppress an abnormal integration. Ripple components due to a generation of output current unbalance can be suppressed by limiting the corrections to the falling edges and rising edges of the PWM pulse train signal to either one according to a polarity of the deviation between the output currents of the power inverting units.

Abstract: This receiver is equipped with a decoder for decoding traffic messages received digitally encoded. In a memory in the broadcast receiver, the broadcast transmitters which can be received in a relatively large region such as, for example, Germany or Europe, are stored by frequency and type, as is the information about the smaller region in which these broadcast transmitters are situated. During a station search, all audible broadcast transmitters are detected and stored and compared with the table. From this, the relatively small region in which the broadcast receiver is located is determined. This determination takes place in such a manner that the usual broadcast reception is not disturbed, namely during traffic announcements, during the initiation of a station search by the user or during the monitoring of stored information on an audio medium. <IMAGE>

Abstract: This invention relates to the problem of making efficient use of resources in broadband telecommunications networks when handling bursty data traffic. 
     A new technique is provided to shape the data traffic profile in order to maximise the efficiency of the bandwidth reservation scheme whilst guaranteeing a defined quality of service in terms of data loss and delay. 
     The shaper, called the Fast Bandwidth Reservation Shaper (FBRS), is essentially a FIFO buffer with three thresholds (T1-T3), a server and an FRP control function which monitors the state of the queue and its associated thresholds, alters the service rate of the server and handles the FRP protocol. 
     By careful choice of the three thresholds and service rates, the FBRS can improve the efficiency of fast bandwidth allocation schemes by reducing the peak bitrate and increasing the duration of small data bursts and by guaranteeing a minimum burst duration, for all but the smallest data bursts, that is in excess of the round trip delay.
