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： An electromechanical transducer of the invention comprises a structural unit, an armature, and the first and second elastic units. The structural unit includes magnets, a yoke and a coil. The armature includes an inner portion disposed to pass through inside the structural unit and two outer portions protruding from the inner portion in a first direction, and the armature constitutes a magnetic circuit with the structural unit via two regions through which components of the magnetic flux flow in reverse directions in the inner region. The elastic units give restoring forces to the outer portions in response to displacement of the armature due to magnetic forces of the magnetic circuit. In the armature, a cross-sectional area at a predetermined position between the two regions is smaller than that at the two regions, and magnetic flux flowing in the first direction within a range of displacement of the armature.

摘要： A particle counter for chemical solution in this disclosure uses a flow cell through which a chemical solution including particles flows, a laser light, and a light-receiving element array. Scattered light from the particles passing through a detection region on an optical path of the laser light in the flow cell is condensed to the light-receiving element array. The laser light in the center of the detection region has an energy density of 3×108 mW/cm2 or more. Each of plural light-receiving elements (a) is larger in length and width than a spot diameter of the scattered light, and (b) receives the scattered light from a region with a size of 760 μm2 or less included in the detection region. The signal processing unit counts the particles passing through the detection region by use of a threshold corresponding to the smallest measurable particle size of 0.03 μm.

摘要： A particle counting system includes a collector, a liquid input/output operation executing means, and a particle counter. The collector performs a collecting operation to introduce the surrounding air into a container storing a liquid to collect airborne particles in the liquid. The liquid input/output operation executing means executes a series of liquid input/output operations to supply an additional liquid for the collecting operation to the collector and discharge the liquid after the collecting operation from the collector. The particle counter measures the number of particles contained in the liquid discharged from the collector with the series of liquid input/output operations.

摘要： A hearing aid device for processing an input sound signal via a microphone so as to output a sound signal from an earphone comprises a signal processing element, a couple of acoustic nerve excitation pattern calculation elements, a couple of acoustic filter shape memory elements, a comparison element, a correction processing element, etc. The couple of acoustic nerve excitation pattern calculation elements calculate acoustic nerve excitation patterns of a normal hearing person and a hearing impaired person based on an output signal of the signal processing element and acoustic filter shapes of the normal hearing person and the hearing impaired person which are stored in the couple of acoustic filter shape memory elements. Each of the acoustic nerve excitation patterns is compared via the comparison element. Then, the correction processing element corrects the input sound signal such that the acoustic nerve excitation pattern of the hearing impaired person is identical with the acoustic nerve excitation pattern of the normal hearing person, so as to generate an output sound signal.
