Abstract: An information of a network to which a new function unit has been added is easily acquired. A relay device installed in a vehicle includes: a detection unit configured to detect a new function unit being a function unit that is newly added to a network including an existing function unit being one or a plurality of function units; a relay unit configured to relay a frame between the function units; and an acquisition unit configured to acquire, from the frame, relayed by the relay unit, between the new function unit detected by the detection unit and the existing function unit, function unit information that includes information regarding a network configuration of a layer of a lower order than an application layer, the function unit information being of at least one of the new function unit and the existing function unit.

Abstract: Provided is, for example, a cleaner sheet including: a cleaning surface that is configured to be brought into sliding contact with a surface of an object to be cleaned. The cleaning surface has unevenness, and includes projections respectively having distal ends configured to be in sliding contact with the object to be cleaned when in use. The projections are constituted by a member formed to have the projections arranged at intervals from each other in a plane direction of the cleaning surface. The member has a hardness of 0.4 MPa or more measured by a nano-indentation method. The cleaning surface further includes adhesive recesses that have higher adhesive force than that of the member and are exposed on the cleaning surface.

Abstract: Provided is a sticky cleaner whose adhesive face can be easily renewed and whish is less susceptible to roll-loosening. The sticky cleaner provided by this invention comprises a PSA tape having an adhesive face on the first face of a substrate. The PSA tape forms a PSA tape roll wound with the adhesive face on the outside. On the first face of the substrate, the PSA tape comprises a first layer formed of a PSA and a second layer formed of an acrylic viscoelastic material. The adhesive face comprises first sections where the first layer is exposed and second sections where the second layer is exposed. The second sections protrude further out of the PSA tape roll relative to the first sections. The PSA tape roll shows an unwinding force F0 at 0° C. and an unwinding force F30 at 30° C.
