Abstract:
A facsimile section receives and decodes data transmitted through a communication line, converts the received data into dot image data line by line, and further performs resolution conversion of the data using a resolution converter. The data subjected to the resolution conversion is transferred to a printer section through a Centronics interface. When data of an entire line is all white, a white-skip command is transferred for that line. The printer section performs horizontal/vertical conversion of the transferred dot image data and data corresponding to the transferred white-skip command using a horizontal/-vertical converter, the converted data being stored in a scan buffer. When the scan buffer is full of the data for one scan, a recording head is driven to record an image. In an image communicating apparatus comprising the facsimile section and the printer section, the load of the control unit of the facsimile section can be diminished, and the time required for the recording can be reduced, with the above arrangement.
Abstract:
In a recording apparatus with plural sheet cassettes of different sizes, a cassette selecting method consists of calculating cassette information for each cassette based on the length and width of the image to be recorded, comparing the cassette information for the different cassettes and selecting an optimum cassette according to the comparison. The cassette information becomes larger in magnitude as the priority for selection becomes higher, represent various image forming modes.
Abstract:
A communication device includes a storage medium for storing a program and information used to detect any error in the program, to prevent the communication device from further abnormal operation when an error occurs in the stored program. The occurrence of an error in the program is detected by performing a calculation based on the stored program, and comparing the result of the calculation with the above-described information stored in the storage medium. A predetermined operation is further performed depending on the result of the comparison.
Abstract:
A facsimile apparatus capable of executing a first protocol for identifying a modem type includes a unit for determining, on the basis of a signal received in accordance with the first protocol, whether polling reception is to be performed, and a unit for transmitting a digital transmission command signal according to a T.30 protocol in accordance with determination by the determination unit.
Abstract:
In a data communication apparatus, the baud rate and the bit rate of a modem thereof are set independently of each other according to the condition of data communication. Thus, optimum data communication suited to the line condition can be performed.
Abstract:
A facsimile apparatus determines whether a frame to be transmitted is an image block or an error retransmission frame, and transmits a short training sequence or a long training sequence based on the results of the determination. The long training sequence is sent if a TCF signal is transmitted and the short training sequence is sent if the image block is transmitted. If the facsimile apparatus is on the receiving side, a training sequence in accordance with the frame from the transmitting side is received. After a carrier signal is detected, the apparatus then makes a transition to a mode for receiving the TCF signal or image block.
Abstract:
A single indicator in a facsimile apparatus time-sharingly indicates a plurality of kinds of information associated with the distant side of communication or indicates that the communication is being performed, thereby increasing an amount of information to be indicated and simplifying the indicator, then leading to a miniaturization of the apparatus.

Abstract:
A process of producing methyl methacrylate polymers is provided wherein the monomer are polymerized by a bulk polymerization procedure at 150.degree. to 180.degree.C with a conversion of 50 to 80% and the volatiles predominantly comprised of the unreacted monomer, separated from the polymer product, are cyclically reused as a part of the monomer feed for polymerization. In such a monomer feed cycle system, oligomers are substantially removed from the volatiles and then the volatiles are blended with a virgin monomer feed for polymerization, the content in the volatiles of impurities having boiling points of lower than 200.degree.C at normal pressure is maintained within the range of 5 to 20% by weight.
Abstract:
A reactor 1 of the present invention includes a coil 2 and a magnetic core 3 disposed inside and outside the coil 2 to form a closed magnetic path. At least part of the magnetic core 3 is made of a composite material containing a magnetic substance powder and a resin containing the powder being dispersed therein. The magnetic substance powder contains powders respectively made of a plurality of materials differing in the relative permeability, representatively, a pure iron powder and an iron alloy powder. Thanks to provision of the magnetic core 3 made of the composite material containing magnetic substance powders made of different types of materials, the reactor 1 achieves both a high saturation magnetic flux density and a low-loss characteristic.
