Abstract: A detection device includes an acquirer that acquires a video of each of a plurality of bearings of a structure including the plurality of bearings, an extractor that extracts a dynamic feature corresponding to a plurality of degrees of freedom of each of the plurality of bearings based on the video, and an identifier that identifies, among the plurality of bearings, a bearing whose dynamic feature fails to match a dynamic feature of one or more other bearings of the plurality of bearings.

Abstract: When an operation knob 10 formed of silicone rubber is pushed laterally, a stem 7 tilts with a contact portion (i) as a fulcrum, a push button portion 6b is pushed, and a contact point in a switch mechanism portion 6a operates to turn on a switch circuit. Even if, by a large operating force F3 being applied, the operation knob 10 is extended and the inner surface portion 15, which is a ceiling surface of an internal space 13 of the operation knob 10, rides on an upper end portion 7c, a reinforcing surface 19 provided on the inner surface portion 15 slides on the upper end portion 7c, and the operation knob 10 returns to the initial shape.

Abstract: A conversion parameter calculation method includes: obtaining, from an image capturing device, image data obtained by the image capturing device capturing an image of an object having attached thereto a marker with which specific coordinates are detectable; obtaining displacement direction information indicating a direction of a displacement of the object, the direction crossing an image capturing surface of the image capturing device; detecting specific coordinates, based on the marker included in the image data; estimating a position of the image capturing device, based on a result of the detection; calculating distance data indicating a distance from the image capturing device to the object, based on the position of the image capturing device; and calculating, using the distance data and the displacement direction information, a conversion parameter for converting a pixel displacement amount of the object into an actual displacement amount.

Abstract: A prediction device for predicting the growth direction of a crack that occurs in a subject includes: an obtainer that obtains video of the subject; a derivation unit that derives displacement of each of a plurality of regions in the obtained video; a selector that selects, from among the plurality of regions, two or more regions each having displacement similar to displacement of a reference region included in the plurality of regions; and an identification unit that identifies, as the growth direction, the longitudinal direction of a collective region made up of the two or more selected regions.

Abstract: A push button device for an endoscope includes: a connection member having a bottomed tubular shape and provided to a finger placement member, the finger placement member having elasticity and disposed on an exterior member of the endoscope; a first stem that has an upper end portion inserted and fitted into the connection member and that is slidably and swingably disposed; a second stem slidably and swingably provided and configured to move in conjunction with motion of the first stem; an immobile member slidably and swingably holding the first stem and the second stem; and a switch configured to be switched by displacement of the second stem moving in conjunction with the motion of the first stem when the finger placement member is pushed.

Abstract: A switching device includes a switch unit with a contact structure and a first operation shaft. The switching device includes a second flange with a contact portion to be in contact with the first operation shaft, and includes a second operation shaft. The switching device includes a holding member with an engagement portion to be engaged with an upper surface of the second flange. The switching device includes a switch operator in which the holding member is inserted. When a lateral pressing force is applied to the switch operator, a second contact portion between the second flange and the engagement portion serves as a support, and thus the second operation shaft rotates with the support. The first operation shaft rotates in accordance with the rotation of the second operation shaft, so that the contact structure is electrically conductive.

Abstract: A push button mechanism for an endoscope includes: a first stem having a first longitudinal direction and having a first end portion connected inside a finger placement member; a second stem having a first end face in contact with a second end portion of the first stem and slidably provided along a second longitudinal direction having a predetermined angle relative to the first longitudinal direction; a switch configured to be switched by the second stem sliding in the second longitudinal direction in contact with the second end portion of the first stem moving in conjunction with the finger placement member; and an immobile member including a space in which the second end portion of the first stem is housed, and the space has a sectional shape similar to the second end portion formed in a deformed shape and prevents rotation of the first stem.

Abstract: A printed circuit board having an insulating board and a plurality of wiring patterns formed over the insulating board by screen printing and provided with first conductive pattern bent parts and wiring parts linked to the first conductive pattern bent parts. A pattern width in the first conductive pattern bent parts is greater than that of the patterns of those of the wiring parts positioned close to and on both sides of the first conductive pattern bent parts.

Abstract: A printed circuit board having an insulating board and a plurality of wiring patterns formed over the insulating board by screen printing and provided with first conductive pattern bent parts and wiring parts linked to the first conductive pattern bent parts. The gaps between adjoining ones of the first conductive pattern bent parts are formed wider than those between those of the wiring parts positioned close to and on both sides of the first conductive pattern bent parts.

Abstract: The printed circuit board according to the invention is highly reliable because a gap width between adjoining first conductive pattern bent parts is formed greater than a gap width in those of wiring parts positioned close to and on both sides of the first conductive pattern bent parts and accordingly, even if any running part arises in the conductive pattern bent parts, short-circuiting is unlikely to occur between wiring patterns, thus making the printed circuit board reliable.

Abstract: A reliable printed circuit board is provided, which has breaks reduced at a bent portion of the trace patterns. The printed circuit board is provided with the trace patterns with the bent portion that is wider in pattern width than the trace portions located near both ends of the bent portion. This allows a more area to remain on the bent portion than on the prior-art bent portion and thereby provides a highly reliable trace pattern without causing a break thereon even when a patchy portion or the like is produced by printing at the bent portion.
