摘要： A waveguide type optical device includes a substrate where a waveguide is formed; a supplemental plate connected on the substrate by using an adhesive; and a groove forming part formed by cutting through the supplemental plate so as to reach the substrate and cut the waveguide, the groove forming part being where a functional thin film is inserted. The supplemental plate and the waveguide adhere to each other or come close to each other in a range not influencing a mode of light.

摘要： Optical waveguides (A) and (B) of a Mach-Zehnder modulator is normally formed on a −Z plane as an electric polarization non-inversion area. However, when the signal electrode 11 and the ground electrode 10 are provided asymmetrically on two waveguides, chirp occurs in output light, which is undesired. Therefore, these electrodes are provided symmetrically about the two waveguides. To effectively perform optical modulation, a part of the substrate in which an optical waveguide exists is to be electric polarization-inverted. As a result of the electric polarization inversion the optical waveguide is on the +Z plane. However, electric charge is accumulated on the +Z plane from unstable spontaneous electric polarization of an electric polarization inversion area, and has undesired influence on the performance of the optical modulator. Therefore, a conductive amorphous layer is formed on the surface of the electric polarization inversion area.

摘要： An automatic analyzer uses probes for detecting liquid levels based on a capacitance detection method. Erroneous detection of liquid levels due to interference caused by the frequency difference of oscillators is reducted. When frequencies f1 and f2 of respective detector oscillators, which are originally equal to each other, are different by approximately several Hz from each other due to a manufacturing variation, oscillation waveforms are added to liquid level detection voltages, causing a premature determination that the probes have contacted the liquid surface before actual contact therewith. By setting the difference between the frequencies f1 and f2 of the detector oscillators to be in the range of several kHz, an oscillation waveform corresponding to the difference between the frequencies is added to the detection voltages, but the amplitude values of the high-frequency components are attenuated by high-frequency attenuators, thereby ensuring accuracy in the liquid level detection.
摘要翻译：自动分析仪根据电容检测方法使用探针检测液位。由于振荡器频率差引起的干扰导致的液位错误检测被减少。原来彼此相等的各检测器振荡器的频率f1和f2由于制造变化而彼此相差大约几赫兹，所以将振荡波形加到液位检测电压上，导致探针在与其实际接触之前接触了液面。通过将检测器振荡器的频率f1和f2之间的差设置在几kHz的范围内，将与频率之间的差相对应的振荡波形加到检测电压上，而将高频分量的振幅值被高频衰减器衰减，从而确保液位检测的精度。
