Abstract: A protective sheet for preventing scratches which comprises a substrate (1) having one face exhibiting the self-sticking property and a foam rubber layer (3) disposed on the other face of the substrate (1) and, in particular, the protective sheet for preventing scratches described above which further comprises a sheet layer (5) which is disposed on the foam rubber layer (3) and exhibits releasing property from the face exhibiting the self-sticking property of the substrate (1). The protective sheet is used for protecting the surface of various articles, in particular, for preventing scratches on coated portions of panels of the body in the assembly step of vehicles.

Abstract: A measuring body is provided in a fluid path between a pump and a fuel injection valve, a flow amount for which is measured. An inner space of the measuring body is divided into a first and a second fluid chambers by a partitioning wall, wherein the first and second fluid chambers are, respectively, operatively connected to the pump and the fuel injection valve. A movable member (float) is slidably inserted into a through-hole formed in the partitioning wall, so that both ends are respectively exposed to the first and second fluid chambers. When the fuel injection is carried out by the fuel injection valve, the fluid in the second fluid chamber is decreased corresponding to the amount of injected fluid, and thereby the float is moved in a direction from the first to the second fluid chamber. The amount of the injected fluid is measured by detecting the movement of the float.
