    摘要： An electroacoustic transducer includes an electromechanical transducer and a casing. The electromechanical transducer transduces an electric signal into mechanical vibration. The housing can be attached to a cavum conchae without blocking an external auditory canal, in which the electromechanical transducer is housed, and vibrates due to the mechanical vibration caused by the electromechanical transducer to generate sound. The housing includes an inner housing portion located on the external auditory canal side and an outer housing portion located on an external environment side when the housing is attached to the cavum conchae. The housing has an ellipsoidal shape or an oval shape.

    摘要： The electromechanical transducer is provided with: a structure portion in which a magnet, yokes, and a coil are integrally arranged; an armature which includes an inner portion penetrating through an internal space of the structure portion along a central axis in the X-direction, and outer portions, constitutes a magnetic circuit with the structure portion, and is displaced in the Z-direction; and elastic members providing the armature with a recovery force. Each of the elastic members has a first and a second engaging portions. A width in which a force in the Z-direction acts between each of the elastic members and the structure portion via the first engaging portion has a first distance. A width between each of the elastic members and the outer portion via the second engaging portion has a second distance in the Y-direction, wherein the dimension condition of 2a>2×2b is set.

    摘要： A microbial particle measuring apparatus includes: a light emitter configured to irradiate a fluid with light of a predetermined wavelength over a predetermined measurement time; a fluorescence receiver configured to selectively receive fluorescence emitted from particles contained in the fluid and output a signal having a magnitude corresponding to intensity of the fluorescence; a signal acquisition unit configured to obtain the signal output from the fluorescence receiver at regular intervals over the measurement time; and a determiner configured to calculate a slope of waveform of the signal obtained by the signal acquisition unit, and determine a concentration of microbial particles contained in the fluid using an attenuation amount of fluorescence intensity generated in a time period in which the slope in the measurement time is smaller than a predetermined value as an amount of attenuation derived from the microbial particles.

    摘要： An in-fluid floating substance measurement flow cell includes: a main body having at least a predetermined portion made of a material having translucency; and a flow passage formed inside the main body, having both end openings at an outer surface of the main body in a substantially identical direction, and configured such that fluid flows in the flow passage. The flow passage has a predetermined section arranged between two opposing flat wall surfaces facing each other, and the predetermined portion includes the predetermined section.
