To grasp a state of a combustion apparatus based on a flame state of a burner, a discharge number measurement unit measures the number of discharges of a flame sensor per unit time, and a light emission information generation unit generates, as light emission information, information obtained based on a value obtained by dividing a total (accumulation) of the number of discharges per unit time measured by the discharge number measurement unit by a total measurement time, and a display unit displays the light emission information generated by the light emission information generation unit. Since the light emission information corresponds to a combustion amount, a change in a combustion state is capable of being grasped more finely by confirming a change in the light emission information displayed on the display unit, and a fine abnormality in a combustion apparatus is capable of being detected.

Abstract

A spectrum measuring device according to the present disclosure includes an accommodation part having a space for accommodating a culture solution containing a medium and cells, a light source device for irradiating a first surface of the space with excitation light, a light receiving device for receiving fluorescence occurring from the first surface, and an arithmetic device for spectral analysis of the fluorescence received by the light receiving device. In the space, the depth from the first surface of a fluorescence region where fluorescence is produced by incident excitation light is a value giving an internal shield of a prescribed level of less in the fluorescence region. The arithmetic device calculates the fluorescence spectrum of the cells by subtracting the fluorescence spectrum of the medium from the spectrum of the fluorescence of the culture solution obtained by the light receiving device.

Abstract

A pressure sensor includes a movable electrode formed in a movable region of a diaphragm, and a fixed electrode formed opposite to the movable electrode. A pressure receiving surface of the diaphragm is held in an inactive state. The inactive pressure receiving surface of the diaphragm is in a state in which molecules of gas to be measured are hard to absorb onto the pressure receiving surface. The pressure receiving surface of the diaphragm can be made inactive by predetermined surface treatment. A layer for making the pressure receiving surface of the diaphragm inactive is formed by the surface treatment, and the pressure receiving surface of the diaphragm is held inactive with the presence of the layer.

Abstract

This wireless sensor comprises: an antenna 10 configured to receive power via electromagnetic waves; an impedance changing circuit 20 connected to the antenna 10; and a measuring unit 40 connected to the impedance changing circuit 20 and configured to measure an object to be measured. If the antenna 10 receives power equal to or more than a prescribed value, the impedance changing circuit 20 changes an input impedance of the impedance changing circuit 20 so that the difference between an output impedance of the antenna 10 and the input impedance of the impedance changing circuit 20 is increased.

Abstract

A pressure sensor (10) comprises: a sensor body (40) that includes a diaphragm (20) including a first principal surface for receiving the pressure of a fluid to be measured and a second principal surface positioned on the side opposite the first principal surface, and that includes a housing (30) that is continuous with and connects to the outer peripheral edge of the diaphragm (20) and supports the diaphragm; a sensing unit (50) that is provided on the second principal surface in order to detect a deformation of the diaphragm (20), and that outputs a first value based on the deformation of the diaphragm (20); a temperature measurement unit (60) for measuring the temperatures of at least two locations on the sensor body (40); a correction unit (70) for correcting the first value by using the measured temperatures of the at least two locations; and a pressure calculation unit (80) for calculating the pressure of the fluid from the corrected first value. The foregoing makes it possible to suppress the impact of output fluctuation caused by thermal deformation of the diaphragm (20).

Abstract

The present invention comprises: a sensor element (21) that detects a pressure; a sensor package (3) that stores the sensor element (21); and a support structure (32) that supports the sensor element (21) inside the sensor package (3). The support structure 32 has: a ring-shaped support diaphragm (14) of which the outer edge is fixed to the package; and a pedestal member (41) that is formed of a material having a thermal expansion coefficient within a predetermined range and sandwiches the support diaphragm (14) between the pedestal member and the sensor element (21). The sensor element (21) is joined to the support diaphragm (14) in a state in which an opening portion (14a) of the support diaphragm (14) is closed. The pedestal member (41) has a pressure guiding portion (42), and is joined to the support diaphragm (14) such that the pressure guiding portion overlaps the opening portion (14a) of the support diaphragm (14). According to the present invention, it is possible to reduce size and manufacturing costs.
