Abstract: A challenge is to provide an art to identify mice as individuals from captured images of one or more mice that are doing activity in a predetermined activity range. An image processing device includes an image acquisition unit, a part extraction unit, and an individual identification unit. The image acquisition unit acquires a captured video of a state in which one or more animals are doing activity in a predetermined activity range. An outline detection unit extracts the outlines of the bodies of the one or more animals from each of multiple unit images included in the video. The individual identification unit analyzes the multiple outlines detected from each of the multiple unit images by the outline detection unit, in a time-series manner and identifies the one or more animals as individuals in each of the unit images on the basis of the analysis results. Thus, the challenge is solved.

Abstract: A pile to be inserted into a beforehand excavated hole, includes a main body being comprised of a hollow pipe, a circular bottom plate fixed at a lower end of the main body coaxially with the main body, a through-hole being formed therethrough outside of the main body, a hollow test pipe having an outer diameter such that the test pipe can be detachably inserted into the through-hole, and a cap being attached to a lower surface of the bottom plate so as to close the through-hole, S1:S2=W1:W2, wherein S1 indicates a surface area of the bottom plate, S2 indicates a surface area of the cap, W1 indicates a weight of a second drop hammer to fall in the main body, and W2 indicates a weight of the first drop hammer.

Abstract: A high frequency apparatus includes an input terminal 21, a high frequency filter 22 to which a signal input into the input terminal 21 is supplied, a mixer 24, one input of which an output signal of the high frequency filter 22 is supplied to and an other input of which an output signal of a local oscillator 23 is supplied to, an intermediate frequency filter 25 to which an output signal of the mixer 24 is supplied, an output terminal 27 to which an output signal of the intermediate frequency filter 25 is supplied, and an electronic switch 30. The electronic switch is provided in the vicinity of the intermediate frequency filter 25, for making a passband characteristic of the intermediate frequency filter 25 substantially flat by closing both contacts, wherein opening and closing of the electronic switch 30 is controlled externally. Accordingly, the adjusting error of the high frequency filter can be reduced.

Abstract: A radio-frequency device has a distributor and a tuner. The distributor has an input terminal which is disposed on one side face of a case; an output terminal which is disposed on another side face; and an output terminal which is disposed on the upper side face. The output terminal, and an input terminal of the tuner are respectively protruded at positions which are separated from the bottom face by a substantially same distance. A metal flat plate portion is led out from the side of the distributor and coupled to a receiving portion of the tuner on the side of the input terminal. Therefore, the output terminal of the distributor is directly connected to the input terminal of the tuner, so that a radio-frequency cable for connecting the units to each other is not necessary. A space reduction and a low production cost can be realized.

Abstract: In a variable capacitance tuning circuit for high-frequency signals, a first varactor diode is connected between either the receiving end or feeding end and ground, one end of a tuning coil is connected to the receiving end or feeding end, and a second varactor diode is connected between the other end of the tuning coil and ground.
