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： An electromechanical transducer of the invention comprises a structural unit, an armature, and two elastic units. The structural unit includes magnets, a yoke and a coil. The armature has an inner portion disposed to pass through inside the structural unit and two outer portions protruding from the inner portion, 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. Each of the elastic units includes a pair of elastic members symmetrically arranged via the armature in a direction of the displacement. Each of the elastic members has one end engaging one of the outer portions and another end engaging one of the elastic member attaching portions.

摘要： If input signal is transmitted to a main body unit, a sensor amplifier stores the input signal in itself as measurement data, and transmits the input signal with the added transfer order information to the main body unit. By checking the transfer order information added to the input signal, the main body unit can confirm if the input signal is deficient or not. Upon the end of the measurement of the physical quantity, the main body unit transmits the retransmission request that requests the retransmission of the deficient portion of the data to the sensor amplifier. According to the retransmission request from the main body unit, the sensor amplifier extracts the deficient portion of the input signal data stored in itself and retransmits the extracted input signal data to the main body unit.

摘要： A viable particle counting apparatus 77 includes devices 10, 70, 2. The device 10 radiates a light with a predetermined wavelength toward a liquid containing a detection target. The device 70 reduces a Raman-scattered light emitted from the liquid out of lights emitted due to an interaction of the light radiated by the device 10 with the target or the liquid and selects an autofluorescence light emitted from the target. The device 2 determines whether or not the target contained in the liquid is a viable particle, based on a light obtained after the Raman-scattered light is reduced by the device 70. The device 10 radiates the light with a wavelength that causes the autofluorescence light and the Raman-scattered light to be different in peak wavelength.

摘要： For an easy calibration using calibration particles, provided is a measuring device to capture images of target objects. An image analyzer acquires multiple images obtained at a predetermined time interval, (a) specifies the mean-square displacement of a bright point of a calibration particle based on the displacement of the bright point of the calibration particle in the multiple images in a calibration mode, and (b) specifies the mean-square displacement of a bright point of the target particle based on the displacement of the bright point of the target particle in the multiple images in a measurement mode. A particle size analyzer (c) derives the particle size of the target particle from the mean-square displacement of the bright point of the target particle based on the mean-square displacement of the bright point of the calibration particle and the particle size of the calibration particle in an analysis mode.

摘要： Provided is a particle measurement device in which irradiation light emitted by a light source is expanded by an expander in a shape satisfying the requirements of a diffractive optical element, converted into parallel light, and made to enter the diffractive optical element. The diffractive optical element shapes the irradiation light entering therein into a flat top beam in which the cross section in the focal position thereof has an elongate rectangle shape. The intensity distribution of light can be made substantially uniform in a detection area formed by the shaped irradiation light.
