Abstract: A jointed structure comprising at least two kinds of oxide superconductor having different melting points, higher melting point superconductor (8) and one lower melting point oxide superconductor (12) being alternately jointed. In this jointed structure, the lower melting oxide superconductor is used as a joint layer for the higher melting oxide superconductors. The jointed structure can be obtained by combining an Y-Ba-Cu-O oxide superconducting material and a Bi-Sr-Ca-Cu-O oxide superconducting material, or by combin­ing two Bi-Sr-Ca-Cu-O oxide superconducting materials of different compositions and accordingly of different melting points. Large cylindrical structures used as, for example, a container for apparatus for biomagnetism measurement can be produced by jointing two or more divided cylindrical parts. In this case, the technique of the jointed structure of the present invention can be applied for jointing of the divided cylindrical parts. The cylindrical structure produced by jointing divided cylindrical parts according to the present invention can prevent the incoming of geomagnetism, thereby enabling reliable measurement of biomagnetism.

Abstract: A transmission arrangement is disclosed which facilitates compression of modem modulated facsimile signals for transmission on digital facilities. The presence of a facsimile call is detected and facsimile control messages are obtained by demodulating and interpreting the facsimile call control protocol. A controller is responsive to the obtained control messages for controlling a voiceband encoder to encode the control portion of the facsimile call and for controlling a so-called facsimile page demodulator to demodulate any facsimile page portions of the facsimile call to obtain a baseband digital bit stream. The presence of prescribed tone signals, i.e., echo protection tone (EPT) signals, is detected in the facsimile call. EPT control messages representative of the EPT signals are generated. The encoded control portion of the facsimile call and the baseband digital bit stream representative of the demodulated, i.e., compressed, facsimile page portion of the facsimile call are transmitted along with control information (as side information) and the EPT control messages to a receiver. At the receiver, a replica of the original modem modulated facsimile signal is reconstructed in response to the control information and by decoding the control portion of the facsimile call and by remodulating the digital bit stream representative of the facsimile page portion of the facsimile call. If EPT control messages are received, the corresponding echo protection tone signal is regenerated for inclusion in the remodulated facsimile signal.

Abstract: An optical system (10) for producing dual fields of view simultaneously. The system (10) includes a first optical system (12) for producing a first field of view image and a second optical system (36) for producing a second field of view image where the angular displacement of the second field of view is different from that of the first field of view. A dichroic beamsplitter (22) is disposed in the present invention so as to reflect light from the first optical system (12). The dichroic beamsplitter (22) is also disposed so as to simultaneously transmit light from the second optical system(36). As a result, the reflected light (20) is primarily composed of light of a first wavelength band and the transmitted light is primarily composed of a second wavelength band. The light from the two different fields of view are then directed to a dual filter (32) which passes the first wavelength band in one portion and passes the second wavelength band in another portion. Light passing through the dual filter (32) may then be focused onto a sensor (34) which will then detect the first field of view image on one area and simultaneously detect the second field of view image on another area.

Abstract: A digital error check sequence for detecting errors in messages. The error check sequence has a form such that it is distinguishable from a sequence of padding bits, and can thus be employed to both mark the end of the message and determine whether there was an error in the transmission of the message. In one embodiment, the error check sequence includes a single-bit first field and a cyclic redundancy code (CRC) whose least significant bit is always 1. The value of the first field is chosen such that when it is appended to the message, the result is a CRC with a least significant bit of 1. Also disclosed are methods and apparatus for generating the error check sequence and transmission and receiving systems employing the error check sequence.

Abstract: The invention is a device for the provision of various types of information through the medium of a public telephone line. By using a comparatively large capacity semiconductor memory (3) with a fast access time as the memory medium, the invention is able to handle simultaneous calls on more than one telephone line under equivalent conditions. The invention comprises a ROM (3) in which digital data is stored, and a timing signal output means (8), which divides the basic clock time and outputs the resultant timing signals at the required frequency. The invention is also fitted with a plurality of parallel control means (2a-2c), each of which carries out an address count in accordance with the timing signals while at the same time reading out the data corresponding to each successive address from the ROM (3). The invention is also able to read data out in parallel from more than one address in the ROM (3) by allocating and transmitting the timing signals output by said timing output means (8) at equal intervals to each of the control means (2a-2c), said data being subsequently output as appropriate to each of the public telephone lines to which the device according to the invention is connected.

Abstract: A computer operating system manages events. An application program or another part of the operating system defines an event monitor to monitor one or more types of events on its behalf. When each of the monitored events occurs, the event monitor is signalled and stores the event signal. Under certain conditions, the event monitor can notify an event handler, and the event handler can access the stored event signals. The event monitor can be defined and established dynamically, i.e. throughout operation of the computer without stopping or relinking the computer system. In the absence of an event monitor which is interested in an event, signals of the event are nevertheless stored. When an interested event monitor is subsequently established, the previously stored event signals are transferred to the interested event monitor. Thus, the event handler has the benefit of previous event signals. The event can be a trace event, and the event handler associated with each event monitor can receive and handle the trace events in real time.
