Abstract: This invention relates to an image distinguishing device for distinguishing a area surrounded by a marker line (for instance, drawn by a half-tone marking pen) of half tone area on a document image and can be preferably utilized for trimming or masking on the document image, for example, in a digital document copying machine or a facsimile. 
     In the image distinguishing device, the reading data of a document image is binarized with two mutually different threshold values (for instance, the bits corresponding to the white and black area are classified as "0" and bits corresponding to the half tone area are classified as "1"). 
     And the starting point and terminating point of the marker line for each of the scanning lines are detected from the binarized data and the one-dimensional marker line is detected for each line. 
     Continuously, the leadingness and the consecutiveness of the marker line pertaining the plane of the document is distinguished from the mutual relationship of the one-­dimensional marker line for each of the lines as shown in the above. And the area surrounded by the two-dimensional marker line is detected.

Abstract: Fire extinguishing device for gaseous fire-extinguishing agents with a centralised fire alarm system which in the event of a fire alarm being reported initially issues an alarm in the extinguishing area and, after a subsequent delay, triggers the flooding of the extinguishing area with the extinguishing agent. In the event of a fire alarm being reported, a pneumatic and an electrical delay element are driven in parallel by the central control system. Both delay elements are essentially set to the same delay time, their output signals being combined in the manner of an AND logic connection to form a trigger signal for the flow of the extinguishing agent. The impulse for the pneumatic delay element is derived from a pneumatic signal which is triggered by the central control system, serves to activate pneumatic horns and is also directed towards extinguishing area valves which in each case activate an extinguishing area. The associated horn and the associated extinguishing area valve are activated by the central control system in each case under individual control for the respective extinguishing area. <IMAGE>

Abstract: A diplexer for processing polarized energy at separate transmit and receive frequencies. The nature of the polarization may be circular, linear or elliptical, depending upon the phasing associated therewith. The diplexer comprises a waveguide having first and second ports (13,14) disposed at opposite ends thereof. A symmetrical bandpass resonator arrangement (15) is disposed around the periphery of the waveguide and couples energy at the receive frequency out of the waveguide. A symmetrical bandstop resonator arrangement (30,40) is also disposed around the periphery of the waveguide and filters energy at the receive frequency to prevent coupling of received energy to the second port. The bandpass resonators of each of the resonator arrangements generally include tuning members (23) that control the amount of energy coupled from the waveguide and that adjust and balance the polarization components of the energy to maintain the polarization state thereof. A plurality of tuning rings (50,51,52) may be disposed adjacent to the first port that compensate for the impedance mismatch caused by external components coupled to the waveguide. A tuning ring (53) may also be provided at the second port that compensates for impedance mismatch caused by the resonator arrangements. The diplexer is generally an overmoded structure that permits the propagation of higher order modes in the received energy. The symmetry provided in the bandpass resonator arrangement inhibits or prevents the excitation of these higher order modes and hence received energy not coupled out of the diplexer through the second port. Similarly, the symmetrical nature of the bandstop resonator arrangement also inhibits scattering of higher order modes and hence improves the performance of the diplexer.

Abstract: An improved synthesis for PMR-type polyimides, including first preparing a dimer of 5-norbornene-2,3-dicarboxylic acid, or acid ester or anhydride and 4,4′methylenedianiline. This dimer is then reacted with the reaction product of the dimethyl ester (or dianhydride) of 3,3′,4,4′-ben­zophenonetetracarboxylic acid and 4,4′-methylenedianiline. The resulting polyimide prepolymer exhibits superior physical properties and is substantially free of the undesired trimer of 5-norbornene-2,3-dicarboxylic acid, or acid ester or anhydride and 4,4′-methylenedianiline. When this dimer is reacted with 3,3′,4,4′-benzophenonetetracarboxylic acid dianhydride methylenedianiline amic acid mixture, the resulting polyimide prepolymer exhibits superior physical properties.

Abstract: Apparatus and method for recording and/or reproducing an image frame in plural blocks utilizes a memory for storing an image signal for one field. The image signal for one field is then divided into n blocks by reading the image signal from the memory n times where n is an integer equal to at least two. The n divided image signals are then subjected to one-channel signal processing, and the respective image signals subjected to the signal processing are then recorded on a recording medium sequentially in different tracks. During reproduction, if little time is available, only selected ones of the n blocks are read and the entire image is interpolated therefrom.

Abstract: An electronic imaging system develops red, green and blue images of a document in a single pass of the document through the system. The system includes an image sensor which has three time delay and integration (TDI) sensor arrays. Each sensor array is configured to have two optically masked rows of charge coupled devices (CCD's) for every row of CCD's that is used for imaging. The sensor arrays are arranged so that the first row of imaging CCD's on any two successive arrays are separated by a distance of an integer, K, times three times the height of a picture element (pel) of the image of the document that is projected onto the image sensor, plus or minus one pel height. The spectral component of the image of the document that is projected onto the image sensor is changed in sequence from red, to green, to blue. As the spectral component projected onto the image sensor is changed, the image of the document is scanned down the image sensor by a distance of one pel height. By this scheme, each line of pels in the document is imaged in each of the sensor arrays in a respectively different spectral component. A document may be imaged in all three colors in a single pass through the system without having dedicated filters for each of the separate sensor arrays.

Abstract: A telephone station set (100) alerting arrangement preferably uses a speakerphone loudspeaker (140) to produce audible alerting signals (e.g., ringing signals) from locally-generated (105) alerting signals both when the set is on-hook and when the set is off-hook. The present state of the speakerphone control circuit (102) is used to control the volume of the produced audible alerting signals; high-volume alerting signals are supplied to the loudspeaker when the control circuit is in talking state, and low-volume, attenuated, alerting signals are supplied to the loudspeaker when the control circuit is in listening state. The appearance of alerting signals when the speakerphone control circuit is in idle state causes the speakerphone circuit to make a transition to the talking state.
