Abstract: The coating film peeling nut of the present invention has a notch 13 formed in an inner surface of a nut main body 10 on which a female screw 12 is formed, the notch 13 extending in a direction different from that of a lead angle of the female screw 12. The notch 13 is formed helically, and a winding direction thereof is the same as that of the female screw 12. A pitch of the notch 13 is 2 to 10 times a pitch of the female screw 12, and a depth of the notch 13 is 20 to 80% of a thread height of the female screw 12.

Abstract: To identify and track a plurality of objects. An object tracking device 1 includes a frame acquisition unit 31 for acquiring one set of frame data 11 included in moving image data that captures a space where a plurality of objects are present; a distance acquisition unit 32 for acquiring measurement data 12 from measurement of three-dimensional coordinates of points configuring the objects in the space where the objects are present; an object position detection unit 33 for detecting a two-dimensional position of each of the objects from the frame data 11 on the basis of comparison with template data of each of the objects; an object distance detection unit 34 for detecting a plurality of three-dimensional positions of the objects from the measurement data 12; and an associating unit 35 for associating each two-dimensional position from the object position detection unit 33 with the nearest three-dimensional position among the three-dimensional positions from the object distance detection unit 34.

Abstract: There is provided an object tracking apparatus that realizes robust object detection and tracking even for movement fluctuation and observation noise, an object tracking method and a computer program. An object cracking apparatus 1 is an apparatus tracking an object in video, the object tracking apparatus 1 including: a deep learning discriminator 2 which is a discriminator by deep learning; and a particle filter function unit 3 tracking an object by applying a multi-channel feature value of video including feature values by the deep learning discriminator 2 to likelihood evaluation by a particle filter, according to a distance between position information about the multi-channel feature value and position information about each particle.

Abstract: A bolt for peeling a coating film of the present invention includes notch parts for peeling a coating film, the notch parts being formed over a plurality of pitches at top parts of screw threads in a male screw part formed in a shaft part. The bolt is characterized in that the respective notch parts formed over the plurality of pitches are arranged to be greatly inclined at an angle of 40° to 50° to an axial line of the shaft part. Since the respective notch parts can be rolled sequentially, it is possible to form the notch parts to be deeper and sharper than conventional ones and to enhance the coating film peeling performance. Also, the coating film peeled can be discharged efficiently as compared with conventional cases.

Abstract: Provided is a case nut in which a nut that is held inside a case body so as to swing freely is not fixed as a result of electrodeposition coating treatment. The case nut is provided with a case body that is welded to a body, and a nut that is held inside the case body so as to float freely. The nut is provided with a metal nut body and a resin insulating member that is formed on the outside of the nut body and prevents contact of the upper surface, lower surface and outer surfaces of the nut body with the inner wall surfaces of the case body and with the body.

The nut 3 is provided with a metal nut body 4 and a resin insulating member 6 that is formed on the outside of the nut body 4 and prevents contact of the upper surface, lower surface and outer surfaces of the nut body 4 with the inner wall surfaces of the case body 2 and with the body 1.

Abstract: A bolt for peeling a coating film of the present invention includes notch parts 6 for peeling a coating film, the notch parts being formed over a plurality of pitches at top parts of screw threads in a male screw part 3 formed in a shaft part 2. The bolt is characterized in that the respective notch parts 6 formed over the plurality of pitches are arranged to be greatly inclined at an angle of 40° to 50° to an axial line 12 of the shaft part 2. Since the respective notch parts can be rolled sequentially, it is possible to form the notch parts 6 to be deeper and sharper than conventional ones and to enhance the coating film peeling performance. Also, the coating film peeled can be discharged efficiently as compared with conventional cases.
