For the purpose of enabling high-accuracy detection as to whether a molded resin product is a non-defective product or a defective product and advance detection of a molded resin product that may suffer deformation or the like in the future, the present invention relates to an inspection method and a manufacturing method for a molded resin product as well as an inspection device and a manufacturing device for a molded resin product, wherein, in an inspection of a joint interface of a molded resin product divided into a plurality of members, the height positions of defect candidates are measured from the results of detecting X rays radiated via at least two paths when the X rays are transmitted through the molded resin product, which makes it possible to detect a defect with high accuracy.

A device for carrying fuel in aircraft and spacecraft includes a carrier element having a longitudinal axis, and a fuel tank with a side wall and a chamber at least partially delimited by the side wall. The tank is arranged in the carrier element. The chamber and the side wall extend in a direction along the longitudinal axis. The side wall has a pressure-receiving component that converts a pressure from the chamber on the side wall into a contraction force acting on the side wall along the longitudinal axis. The contraction force compensates for an expansion force, resulting from the pressure from the chamber and acting on the side wall along the longitudinal axis. This provides an improved device for carrying fuel in aircraft and spacecraft, wherein the aircraft and spacecraft has constant flight mechanical properties because of the device.
