The invention relates to a rim and to a method for its production, in particular for bicycles, using a machining device for the working a welding burr of the rim. The logic section comprises a digital display data processor and a timing signal generator which generates a timing control signal necessary for the display apparatus and the DA converter converts digital display data obtained by the digital display data processor into analog data. Each remote has a remote ID unique from all other remotes and is stored in non-volatile memory of the computer; and the base station includes a base station ID code unique from all other base stations, and the base station ID is stored in non-volatile memory of each remote. Such a profile prevents conductive material associated with a subsequent bottom electrode layer etch from depositing on the PZT sidewall, thereby preventing leakage or a \u201cshorting out\u201d of the resulting FeRAM capacitor. A plurality of communications interfaces can thus be connected to a single communications port without increasing the upstream transmission bandwidth requirements. With the above arrangement, the meter of the present invention can be adapted to various kinds of machines and instruments.
