Abstract: A calibration area has a rectangular area and a peripheral area. The rectangular area includes a center area provided in the center portion and a first corner area, a second corner area, a third corner area, and a fourth corner area that are set at four corners sequentially in the circumferential direction. The center area has a line symmetry with respect to each of the two orthogonal axes passing through the center of the rectangular area. The heights of the areas are different.

Abstract: A region of a hole-inner circumferential surface composing a portion defining a terminal through-hole, the region being located on the battery case cover side, include a tapered surface gradually enlarged in diameter as extending toward the battery case cover side and opening toward the battery case cover side; when riveting is carried out, a region of a shaft portion, the region being located inward of the tapered surface, is enlarged in diameter so as to form an annular projecting portion in contact with the tapered surface; and a hole circumferential portion located around the portion defining the terminal through-hole is held between the external enlarged-diameter portion and the annular projecting portion so as to fix a first terminal member to a second terminal member.

Abstract: A sealed-type battery includes an exterior body, a collector terminal, a hollow rivet defining a hollow section, and a reverse plate arranged between the collector terminal and the hollow rivet. The collector terminal includes: a projected section projected; a peripheral edge section provided; and a notch section provided in the peripheral edge section in a manner to surround the projected section and formed in a manner to reduce thickness of the collector terminal. In a projected direction of the projected section, the projected section is thicker than the peripheral edge section. A fitting section, to which the projected section is fitted, is provided in the reverse plate. The sealed-type battery includes a welded section that has a top surface opposing the hollow rivet and that joins the collector terminal and the reverse plate at a position between the projected section and the fitting section.

Abstract: A communication apparatus which is connected to an ISDN includes a data input/output (I/O) unit for inputting/outputting data and an ISDN interface to control the data input/output operations between the data I/O unit and the ISDN. The ISDN interface is constructed on a one-chip IC and at least includes an interface for separating B-channel data and D-channel data and for inputting/outputting the data, a switch for switching data paths in accordance with the classification of the information of the B-channel data and a modem which is connected to the path for 3.1K audio in the path of the B-channel data. The ISDN interface further has a speed matching processing circuit for matching the speed of the data which is inputted/outputted to/from the data I/O unit with the speed of 64k non-limit digital data. A commercial power source is supervised and the occurrence of a power failure is detected by a detecting unit.

Abstract: A communicating apparatus having a plurality of ports to connect a plurality of communication lines comprises a memory to store information indicating whether the plurality of communication lines are extensions of a private branch network or not, a designating circuit to designate whether the communication is to be executed through said extensions or not, and a selector to select one of the plurality of ports in accordance with the result of the designation of the designating circuit and the contents of the memory. The memory stores information indicating whether the communication lines are ISDN lines or PSTN lines. The selector includes a call generating circuit for generating a call in the G4 facsimile mode when the selected communication line is an ISDN line and for generating a call in the G3 facsimile mode when it is decided that the partner is not a G4 facsimile apparatus after completion of the call generation.

Abstract: An image transmission device is capable of transmitting image data in different resolutions with different pixel number of the image. The gamma correction values are converted in proportion to the transmittal resolution of the image data and the quasi half-tone which closely follows the original image is reproduced with less degree of omission of minute lines.

Abstract: A data communication apparatus includes an analog communication unit for performing analog communication, an A/D converter for converting the analog signal from the analog communication unit into a digital voice signal, and an ISDN communication control unit for sending the digital voice signal from the A/D converter onto a digital communication line. Data used in an ISDN are voice data, image data, facsimile communication data, etc.

Abstract: A line interface for ISDN channels converts an analog signed from an analog communication terminal to digital data and sends the converted digital data to a B-channel of ISDN. The digital data from the B-channel of ISDN is converted to an analog signal and the converted analog signal is then sent to the analog communication terminal.

Abstract: In a communication apparatus connected to an ISDN and having a telephone function, the arrangement is such that when a call is received from another party's facsimile machine, the number of the sending party received is stored in memory. When depression of a communication start switch by the operator is detected during communication by facsimile, a call is made by telephone based on the stored sending party's number. When a call is made to the other party's fdacsimile machine, the other party's dial number is stored. If it is detected that the operator has taken a handset off the hook during communication by facsimile, a call is made by telephone based on the other party's dial number that has been stored.

Abstract: A facsimile apparatus connected on an ISDN side in a communication network in which the ISDN is connected to a telephone network includes network identifying means for identifying whether an incoming data sending party is an ISDN terminal or a telephone network terminal, CNG signal detecting means for detecting a CNG signal received via a B channel, and changeover means for changing over between automatic reception and manual reception. In a case where the CNG signal is detected, a response is made in a facsimile mode. In a case where the CNG signal is not detected, a response is made in a facsimile mode if automatic reception prevails and in a telephone mode if manual reception prevails. This arrangement eliminates communication failure due to a difference in mode between a calling side and a called side regardless of the network terminal from which a call is received.
