In a TEDS system, a data transmitting and receiving apparatus is provided and a signal transmitted from a TEDS memory to an apparatus side is logically inverted without using a transformer, and further a sneak signal is prevented. Invertersand zener diodesconnected in parallel between the TEDS memory and a data driver of the apparatus are provided. Data transmitted from the TEDS memory to an apparatusside is logically inverted by the inverter, and the logical voltage attenuates by a predetermined amount at the zener diodeto be supplied to the data driver. Since a sneak signalwhose logical voltage attenuates by a predetermined amount again by the zener diodeis supplied to the inverterthe transmission of a logic value is prevented by setting the threshold of the inverterappropriately.

Data transmitting and receiving apparatus

In a small-sized, high precision load cell, an annular fixed section is arranged around a load application section, and the load application section and the fixed section are connected by a plurality of arms. The arms connected to the fixed section are not radial or straight, but are bent. Thus, a direction of extension n of a distortion vulnerable section at which a hole is formed is approximately perpendicular to a straight line m which connects the load application section and the distortion vulnerable section. Therefore, it is possible to prevent tension, which arises when a load is applied to the load application section, from being conveyed to the distortion vulnerable section and to detect only the distortion with a gauge.
