Abstract: In a cooling device 20 of the present invention, a bypass passage 20C for allowing circulating liquid to partly or wholly bypass a heat exchanger 15; a first valve 21; and a second valve 22 are provided. Thus, the a cooling device 20 having a refrigerator 100 capable of cooling to a low temperature can be operated even at high temperature and heat can be removed even when the inspection temperature is high. Thus, the inspection can be performed both cases when the inspection temperature is high and low. Consequently, the semiconductor wafer generating a large amount of heat during the inspection can be also inspected without causing problems.

Abstract: The present invention aims at solving the problem of providing a control device for an unmanned flying object that can elucidate the cause of a fault in the unmanned flying object after the fact and that has a function of desirably preventing a crash before it even happens, and at solving the problem of providing an unmanned flying object that incorporates such a control device. The control device of the present invention is a device for controlling a single rotor blade motor, and includes a calculation device, a storage device, a data output device, and a voltage detection device: the calculation device acquires and outputs information of various types; the storage device accumulates information of various types received from the calculation device; the data output device outputs information from the calculation device to an external control device; and the voltage detection device acquires voltage information from a battery or the like and supplies it to the calculation device.

Abstract: In order to supply a method and a device that can evaluate the fluidity of blood with good sensitivity in a simple manner, there is provided a blood fluidity evaluation method in which a pressure member is pressed against a test site upon a test subject, blood at the test site is squeezed to flow out to the periphery of the test site, change over time of the amount of blood at the test site is measured at this time using optical scattering, and blood fluidity at the test site is evaluated from this measurement data; and, desirably, before the above method, a positioning process is performed in which: the pressure member is pressed against the test site with a weak force; pulse measurement data is acquired due to the absorption of light; and a relative position, at which the intensity of the pulse measurement data attains a local maximum, is determined as being an optimum measurement position.
