Abstract: Provided is a roll body of a band-like patch that can be held in a roll-like form without causing deviated rolling or unrolling, and can allow simple pulling out of a patch without causing stickiness on a person's hand or fingers when being pulled out. In the roll body of a band-like patch formed by rolling a band-like patch including a cloth support, a pressure-sensitive adhesive layer, and a release liner laminated in this order, at least one temporary attachment region in which a temporary attachment layer is formed and at least one grip region in which no temporary attachment layer is formed are provided at an interface between a back face of the cloth support and a back face of the release liner.

Abstract: The detection output of a knock sensor, which detects knock of an internal combustion engine, is filtered by a filter in which the filtering frequency band is variable. The output of the filter is discriminated by a level discriminating unit with respect to a given determination level. A counter counts number c of times at which the detection output of the knock sensor is equal to or higher than the determination level. A determining unit determines whether knock occurs or not on the basis of the number c. In response to the output of the determining unit, when determination of occurrence of knock is impossible, a correcting unit conducts correction of shifting the filtering frequency band of the filter. Therefore, determination of occurrence of knock is enabled, and the accuracy of knock detection is improved.
