Definitions
- FIG. 1A is an axial sectional view showing the structure of a first linear oscillator according to the present invention.
- (B) is a partial cross-sectional view of the linear oscillator in a direction perpendicular to the axis.
- FIG. 12 is a diagram showing a pulse waveform of the output voltage when the pulse waveform is changed to a sine waveform.
- (B) is a diagram showing a panoramic waveform of the output voltage when the pulse waveform is changed to a sawtooth waveform.
- FIG. 13 is a diagram showing a drive voltage waveform controlled according to time.
- FIG. 7 is a cross-sectional view showing the structure of a seventh linear oscillator 107 including a coil spring 60 having fixed portions 60-1, 60-2.
- One end of the coil spring 60 is non-rotatably fixed to the shield case 10 and functions as a fixing portion 60-1.
- the other end of the coil spring 60 is similarly non-rotatably fixed to the plunger 1 and functions as a fixing portion 60-2.
- the coil spring 60 With the fixed parts 60-1 and 60-2, the coil spring 60 not only exerts a spring force in the axial direction of the plunger 1, but also plans a small angle rotation around the axis as it expands and contracts in the axial direction. Jar 1 can be given a rotation over this angle Is regulated.
