摘要:
A vibrator is received within a case and the case is contained in a containing portion. Further, the case is arranged to be supported by the surrounding terminals having first ends thereof embedded in the containing portion. By virtue of the described configuration, the vibrator is securely retained by the case even if strong vibrations are applied to the terminals. With this configuration, an angular velocity sensor ensuring the strength to retain the vibrator even if the vibrator is reduced in size and causing no degradation of the output characteristic even when subjected to strong vibrations can be provided.
摘要:
In an angular velocity sensor including two oscillators, the oscillators are balanced in weight precisely, thus providing improved output characteristics. In the sensor, at least one of the two oscillators has a notch having a surface roughness of not higher than 2 μm on an edge thereof.
