摘要： A strain sensor improved in detection accuracy without variation of bending stresses applied to the strain detecting element. The sensor substrate has a first fixing hole at one end and a second fixing hole at the other end, a detecting hole at the center, and at least one strain detecting element on the upper surface or lower surfce thereof. The first fixing member is press-fitted into the first fixing hole. The second fixing member is press-fitted into the second fixing hole. The detecting member is press-fitted into the detecting hole. Further, when an external force is applied to the detecting member, strain generated due to the positional shift of the detecting member is detected by the strain detecting element with respect to the first fixing member and the second fixing member.

摘要： Synchrotron radiation is generated when a base of charged particles is bent by a bending magnet. The synchrotron radiation passes down a lead-out duct as the total number of pumps is limited by the size of the apparatus and many pumps are needed in order to achieve a good vacuum. An ion pump has a main magnetic field, normally generated by a magnet of the ion pump which controls the behavior of the electrons in the ion pump. However, the leakage magnetic field of the bending magnet affects the ion pump, and therefore the ion pump is arranged so that its main magnetic field is aligned with the leakage magnetic field at the ion pump, or at least with a main component thereof. In this way, the effect of the leakage magnetic field on the ion pump is reduced. Indeed, it is possible to use the leakage magnetic field as the main magnetic field of the ion pump.
