摘要： An optical transmission system is provided in which the optimum operating point of a Mach-Zehnder interferometer, matched to the optical frequency of the light source on the transmitting side, can be set. The optical receiver (2) has an infinitesimal-modulated signal component detection circuit (222), which uses the signal train output from a balanced detection circuit (221) to detect the infinitesimal-modulated signal component applied to the phase adjustment terminal (201) of an MZI (200) by an infinitesimal-modulated signal oscillation circuit (224); a synchronous detection circuit (223), which synchronously detects the infinitesimal-modulated signals output from the infinitesimal-modulated signal component detection circuit (222) and infinitesimal-modulated signal oscillation circuit (224) and detects the error signal component arising from the shift between the optical signal carrier frequency and the optical frequency characteristic of the MZI (200); and a controller (207), which outputs a control signal to adjust the phase difference between two split optical signals output from the MZI (200) so as to correct the shift amount.

摘要： In the method for measuring the velocity of fluid or visualizing the distribution of fluid by feeding tracer particles to the fluid, irradiating the fluid with light and observing return light from the tracer particles, tracer particles containing a flourescent substance are fed at least partially to the fluid and the fluid is irradiated with exciting light to cause the tracer particles to output flourescent emissions. A filter which does not transmit the exciting light is used to substantially selectively observe the flourecent emissions of the tracer particles. This method results in a remarkable improvement in the accuracy of flow velocity measurement or visualization of fluid distribution. Moreover, in a mixed fluid system consisting of two or more different fluids, the pattern of behavior of each fluid and the intermingled state of the fluids can be observed by using a plurality of different tracer particles.

摘要： The disclosed method of measuring the flow of a fluid with a porous particulate ceramic tracer and an optical instrument is characterized in that spherical particles having diameters in the range of 0.5 to 150 &mgr;m are used as the tracer. Inasmuch as the tracer particles for flow measurement are spherical, the sectional area of scattered light to be detected by an optical sensor means is constant regardless of the orientation of particles. Furthermore, spherical particles have no surface irregularities that might cause concatenation so that individual particles are not agglomerated in tracking a fluid flow, thus contributing to improved measurement accuracy.

摘要： An electrically heatable windshield comprises two glass plates bonded to each other with an interlayer therebetween and a transparent conductive layer formed at contacting surface between one of the glass plates and the interlayer so that the windshield is heated by supplying a current to the transparent conductive layer through a bus bar for feeding power. A colored layer such as a ceramic color print is formed at the peripheral portion of the surface, in contact with the interlayer, of at least one of the glass plates. The bus bar is formed on the colored layer without expanding. A transparent protective layer is formed so as to cover the edge portion of the colored layer which is near the center of the glass plates, and the transparent conductive layer is formed over the transparent protective layer.

摘要： A position detector having a magnetic sensor for measuring linear or angular displacement, or detecting a position of a body without contact thereto. The detector has a closed circuit including magnets and yokes. The magnetic leakage flux which emanates from the inside surfaces of the yokes is utilized to detect the position of the body. The magnetic sensor is transferred along the inside surfaces of the yokes by a transferring circuit, which senses the magnetic field intensity of the leakage flux distributed thereon. This enables the detector to have a longer measuring range than that of a prior art detectors. An output signal is stable due to the shielding effect of the yokes. The magnetic closed circuit has many magnetic and mechanical configurations. For example, for the magnet, a permanent magnet and an electromagnet can be used. Further, improvements are proposed for enhancing the linearity of the output signal voltage with respect to the transferring distance of the sensing element and for compensating the offset drift of an amplifier or changing the coercive force of permanent magnets.
