Abstract: A nuclear fusion system comprises: a muon generation unit to generate negative muons including electron and positron accelerators for generating electron and positron beams; a gas supply unit to supply to circulate gaseous deuterium or gaseous deuterium-tritium mixture as raw material gas; a Laval nozzle to accelerate the raw material gas to supersonic velocity; and a shock wave cone connected to the Laval nozzle to introduce the raw material gas accelerated to supersonic velocity to generate an oblique shock wave, the raw material gas accelerated to supersonic velocity being introduced into the shock wave cone to generate the oblique shock wave, the oblique shock wave being decelerated to create a high-density gas target in an in-flight manner, the muons generated as a result of causing electrons and positrons to collide with each other being introduced into the high-density gas target thereby to cause a muon-catalyzed nuclear fusion reaction to occur.

Abstract: To reduce the occurrence of scratches in a wide range of a surface of a protruding portion. Solder is firmly fixed to a first metal film. The first metal film has a surface inclined with respect to a first lower surface.

Abstract: A rider characteristic determining apparatus capable of determining characteristics of a rider controlling a saddle riding type vehicle, and a saddle riding type vehicle including the same, are configured such that the rider's characteristics are determined from a turning movement of the saddle riding type vehicle which reflects results of the rider controlling the saddle riding type vehicle. This enables a stable characteristic determination regardless of individual operation or control by the rider. Further, a turning performance score of the vehicle is calculated based on at least one of vehicle state amounts of a roll direction, a pitch direction and a caster angle which influence the steering angle of the saddle riding type vehicle. This enables a proper evaluation of the turning characteristic of the saddle riding type vehicle.
