Abstract: A signal acquisition unit (2020) acquires a signal. From the signal acquired by the signal acquisition unit (2020), a detection signal extraction unit (2060) extracts, as a detection signal, a signal of any frequency band among a plurality of partial detection frequency bands into which the frequency band that is the subject of detection has been divided. A determination unit (2070) determines, in order, for each detection signal corresponding to each of the different partial detection frequency bands, whether the detection signal shows any leakage, and if at least a prescribed number of the detection signals are not showing any leakage, determines that leakage is not taking place.

Abstract: [Purpose] To provide a link structure in a motor vehicle seat, which realizes a simplified pivotal connection of a link element therein and also ensures that rotation of the link element is maintained so smooth and stable as to avoid rattling and wobbling of the link element. [Means for Achieving the Purpose] In a link structure comprising a movable portion (such as a seat cushion frame D) and a base portion (such as an upper rail member D) retained stationary relative to the movable portion, wherein the movable portion is movable relative to the base portion and connected therewith via a link element 10, there is provided a pivotal connection portion E to which the link element 10 is at a hole portion 10a thereof pivotally connected.

Abstract: A plate is continuously press-bent, into a shaped member having a recess opening at one surface (i.e., lower surface). Then, the plate is bent back by pressing, at the front and rear ends, covering the openings of the recess and a side frame having open cross sections, each with a gap, is thereby formed. In the forming step, the side frame is not welded and has open cross sections, each with a gap. The side frames are then subjected to the next step (i.e., step of assembling the seat frame). In the step of assembling the seat frame, the side frames and coupling members are welded together, constituting a substantially rectangular seat frame. As the side frames are so welded in step of assembling the seat frame, a rigid structure each having closed cross sections with no gaps is formed.

Abstract: A culture container includes a container main body and a filmlike member. The container main body has a recessed part and a bottom part 17 in which a plurality of microwells for containing a cell-culture solution is formed. The filmlike member is a member that is disposed above the plurality of microwells inside the recessed part and limits the movement of each spheroid that has grown inside its corresponding microwell such that the spheroid does not separate from the corresponding microwell. Thus, spheroids can be stably formed in the culture container.

Abstract: A vibration detection device (10) is provided with a vibration detection unit (110), a sensor-side leak determination unit (120), a first transmission unit (130), and a second transmission unit (140). The vibration detection unit (110) detects vibration transmitted through piping (30). The sensor-side leak determination unit (120) determines whether or not there is a possibility of a leak in the piping (30) based on a measurement result of the vibration detection unit (110). When the sensor-side leak determination unit (120) determines that there is a possibility of a leak, the first transmission unit (130) transmits provisional leak information to an information processing device (20). The provisional leak information indicates that there is a possibility of a leak in the piping (30).

Abstract: A protector that lightens a shock when a wearer falls, and reduces an unpleasant feeling given to a wearer when worn for a long period of time. The protector is substantially circular in a plan view and is disposed at a position to cover near a femoral-neck portion from a side portion of a wearer. The protector is curved in a thickness direction so that an outer surface, comprising a single-layer structure composed of a polymer-foam body, is convex, and an inner surface is concave. An amount of displacement in the thickness direction when a load of 20 N is applied at a central portion of the outer surface when placed on a flat surface is 3 mm-20 mm.
