Abstract: A thermal flow-rate sensor includes: a first temperature sensor that detects the temperature at a specified location of the outer-wall surface of a pipe; a heat-transfer element that is arranged on the outer-wall surface of the pipe in a state separated from the first temperature sensor, and that exchanges heat with a measurement medium by heating or cooling the outer-wall surface of the pipe; a second temperature sensor that detects the temperature of a portion of the outer-wall surface of the pipe that is heated or cooled by the heat-transfer element; and a control unit that performs specified processing. A heat-flux sensor is arranged between the heat-transfer element and the outer-wall surface of the pipe and directly detects heat flux between the heat-transfer element and the pipe; and the control unit detects the flow rate of the measurement medium based on the temperature that is directly detected by the first temperature sensor, the temperature that is detected by the second temperature sensor, and the heat flux that is detected by the heat-flux sensor.

Abstract: An measuring instrument for a physiological heat quantity emitted from a human body includes a heat flux sensor, and a calculator. The heat flux sensor includes a sensor main body portion and a moisture absorbing member. The sensor main body portion has multiple through holes penetrating through the sensor main body portion from a first surface to a second surface. The sensor main body portion is disposed on a human body such that the first surface is adjacent to the human body when in use, and outputs a sensor signal according to a heat flux passing through the sensor main body portion from the first surface toward the second surface. The moisture absorbing member is stacked on the second surface of the sensor main body portion. The calculator calculates the physiological heat quantity based on the sensor signal.

Abstract: In a multi-gap rotating electric machine, a side stator coil is received in a side space formed in a housing to connect radially inner and radially outer stator coils across a rotor. A cooling oil flow adjustment member is provided to adjust flow of cooling oil in the side space. The adjustment member has cooling oil guide channels formed on an uneven surface thereof facing the side stator coil. When viewed along a central axis of a rotating shaft: on an upper apart of the uneven surface which is located above the central axis, the cooling oil guide channels spread from a reference line to both sides of the reference line while extending downward; and on a lower part of the uneven surface which is located below the central axis, the cooling oil guide channels converge on the reference line from both sides of the reference line while extending downward.

Abstract: A rotating electric machine includes a rotor, a stator, a cooling device and a pair of cooling liquid collection tanks. The stator includes an annular stator core and a stator coil. The stator core is disposed radially outside the rotor so as to surround the rotor. The stator coil is mounted on the stator core so that a pair of coil ends of the stator coil protrude axially outward respectively from opposite axial end faces of the stator core. The cooling device is configured to supply cooling liquid to vertically upper parts of the coil ends of the stator coil. Each of the cooling liquid collection tanks is arranged to surround a vertically lower part of a corresponding one of the coil ends so as to collect and temporarily reserve therein the cooling liquid moved from the upper part to the lower part of the corresponding coil end.

Abstract: An abnormality diagnostic apparatus includes: a heat flux sensor that detects heat flux generated by a measurement target continuously from the start of operation of the measurement target or at predetermined time intervals; and a control device that determines whether there is an abnormality based on the result of the detection by the heat flux sensor. In the event of an abnormality in a facility, heat flux generated from the facility by at least one of current, voltage, sound, vibration, and friction changes. Therefore, the use of the heat flux sensor makes it possible to determine the presence or absence of an abnormality in the measurement target without using a plurality of kinds of sensors to measure current, voltage, sound, vibration, and friction.

Abstract: In a radiant heat sensor, first and second thermoelectric members are alternately arrayed one by one in a direction along a first surface of a plate-shaped member so as to be separated from each other, and each of the first and second thermoelectric members configure a portion of the first surface. First conductor patterns extend the first surface, disposed on the first surface so as to span a single first thermoelectric member and a single second thermoelectric member that are adjacent to each other, and configure hot contact portions between the first and second thermoelectric members. Second conductor patterns extend along the first surface, disposed on the first surface so as to span a single first thermoelectric member and a single second thermoelectric member that are adjacent to each other, and configure cold contact portions between the first and second thermoelectric members.
