    Abstract: PURPOSE:To surely decrease return light quantity to unrequired reflected light from a substrate end face and to simplify the manufacture of the optical waveguide device by providing the side plane on the light incident side of an optical guidewave inner than the end face on the light incident side of a substrate. CONSTITUTION:The end face 2A on the light incident side of the optical waveguide 2 is formed at the side inner than the end face 1A of the substrate 1. In other words, when light from the light source of a laser beam, etc., is coupled with the optical guidewave 2, the focal point P of a lens 16 is positioned at the end face 2A of the optical guidewave 2, not at the end face 1A of the substrate 1, and light Li from the light source 17 is focused on the end face 2A of the optical guidewave 2. Therefore, reflected light Lo from the substrate end face 1A is diverged without being returned to the light source 17 by the lens 16 after being focused on a position Pi symmetric to the focal point P as for the end face 1A, which decreases the return light quantity to the light source 17. Also, it is possible to surely decrease the return light by setting a gap between the end face 2A of the optical waveguide 2 and the end face 1A of the substrate 1 between 50-500mum.

    Abstract: PURPOSE:To measure the velocity of a high speed measured object precisely and accurately with a simple and small device by multiplying sine wave signals to a signal obtained by interfering a reference light with a measuring light having different phases. CONSTITUTION:A measuring light L3 emitted out of a laser source 3 and reflected by a speaker 2 on a measured object and two referrence lights L2A, L2B with shifted phases by 90 degrees which are separated by way of a spectroscopic means consisting of a polarizer 4, a beam splitter 5, a 1/8 wavelength plate 6 and a fixed mirror are interfered to make interfered lights L4A, L4B. These lights are introduced into light reception elements 9, 10 by way of a polarization beam splitter 8 to obtain detection signals S1, S2 by square-low detection to which sine wave reference signals S3, S4 having a determined frequency omega1 are multiplied 12, 15 to output multipled signals S5, S6. Then the signals S5 and S6 are added to output a frequency-modulated signal S7 to an Fm demodulating circuit 17 and a measured output corresponding to the vibration velocity of the vibration surface of the speaker 2.

    Abstract: PROBLEM TO BE SOLVED: To obtain more satisfactory noise cancellation effects. SOLUTION: A conductor part structured to have electric resistance ratio less than that of magnetic body materials configuring a magnetic circuit is arranged near the voice coil of a driver unit so that electromagnetic induction coupling can be generated between the voice coil and the conductor part, and that the inductance of the voice coil can be reduced. The reduction of the inductance of the voice coil reduces a phase difference between a driving voltage to be applied to the voice coil and driving currents corresponding thereto.

    Abstract: PROBLEM TO BE SOLVED: To attain improvement in sound quality when obtaining an audio output by driving a diaphragm with a magnetostriction actuator.
    SOLUTION: A diaphragm 106 is driven by a magnetostriction actuator 105. As a sensor, a piezoelectric element 107 is disposed between a distal end of a driving rod 153 and the diaphragm 106. The piezoelectric element 107 detects vibration of the diaphragm 106 and outputs a vibration detecting signal. The vibration detecting signal contains information of distortion that occurs in the actuator 105, the diaphragm 106 and the like. An equalizer 102, a subtractor 103, a phase correction circuit 108 and a low-pass filter 109 constitute a correction section. The correction section performs feedback correction upon an audio signal from a signal source 101 based on the vibration detecting signal. The corrected audio signal can correct the distortion that occurs in the actuator 105, the diaphragm 106 and the like, so that the vibration of the diaphragm 106 highly accurately complies with a waveform of the audio signal outputted from the signal source 101, thereby attaining improvement in the sound quality of output audio.
