The inventors have studied a technology for utilizing a fine bubble generation mechanism for generating fine bubbles through water pressure feed and water pressure passage by an AC power supply pump having a pump output of 50 watts or more. However, the inventors have noticed that in such a technology there is a concern about the risk of electric leakage accompanying the use of an AC power supply. The inventors have also noticed that such a technology requires the wiring of a power supply cable, and the minimum size of a fine bubble generation device for obtaining a satisfactory water pressure amount is usually about half the size of a mandarin orange box, and thus it is often difficult to realize the miniaturization of the device. Provided is a fine bubble generation device 1000, wherein a housing 1100 houses a pump 1300, a battery 1400, and a fine bubble generator 1500, and the housing 1100 is sealed so that water 1910 in a water tank 1800 does not enter the inside of the housing 1100.

The present inventors have examined a technology for generating ultrafine bubbles defined as bubbles having a bubble diameter of less than 1 micrometer which is relatively small. However, in such a technology, the confirmation of the minute ultrafine bubbles is not only difficult with the naked eye, but also not easy even with an observation mechanism having a resolution of a microscope resolution level. The present inventors have noticed that there is a concern about the ambiguity that users cannot often confidently confirm the generation of significant bubble-containing purified water. A fine bubble generation device 1000 has: an irradiator 1600 for irradiating water 1910 at a predetermined portion of a pipe inner portion 1230 with a light beam; and an imaging device 1700 for capturing an image of the water 1910 at the predetermined portion. The density of fine bubbles 1920 contained in the water 1910 is measured by analyzing the image of the water 1910 captured by the imaging device 1700.

[Problem] To achieve a cleaning roller capable of effectively cleaning even a dust sticking to a floor without damaging the floor. [Solution] Provided is a cleaning roller 2 in a robot-type cleaning machine. The cleaning roller 2 is mounted to a bottom surface of a machine body 1 and rotates while in contact with a floor to remove dust while adhering to the dust. A porous layer portion 20 made of microfibers is formed on a surface around a center shaft. Part 2a of this porous layer portion 20 is formed harder than another portion 2b. This harder portion 2b is formed in a spiral shape with respect to the center shaft. The porous layer portion 20 can contain water so that the roller can be used for wet wiping.
The inventors of the present invention believe that it is desirable to promote wider use of mobile terminal devices such as smartphones that are supplied with power by lithium-ion batteries through linkage with various devices via the Internet. The inventors of the present invention noticed that control of a fan device that can be attached to clothing, which is attracting attention from the perspective of preventing heat stroke, on the basis of body temperature data using a mobile terminal device has not been realized.

A hybrid system for a UAV having a generator combined with a battery is suited for long-distance commodity delivery work, but often needs an engine shaft-mounted type portable engine starter which includes a starter motor for starting an engine used by the generator. An engine-starting apparatus (300) is for a multirotor helicopter (200) provided with a generator (210) which generates power by using an engine (213), the engine-starting apparatus (300) being provided with an engine start power supply switch (320) that turns on/off power supply to the generator (210) when the engine (213) is started, wherein, when the power supply is turned on by the engine start power supply switch (320), a power generation rotor (211) of the generator (210) rotates with respect to a power generation stator (212) of the generator (210), and thus an engine crankshaft (213s) of the engine (213) is rotated.
The inventor of the present invention considers that a flying object such as a multi-rotor helicopter known as a drone is preferably used for effective information collection for fire-fighting and rescue operations at the site of fire.
