Abstract: A wind tunnel test model (1) includes a half model portion (3) that simulates a fuselage portion of an airframe with a single wing and a supporting apparatus (5) that supports the half model portion rotatably about a central axis. The supporting apparatus has a horizontal cross-sectional shape that is approximately the same as or similar to that of the fuselage portion (7) and extends rearward of the fuselage portion, includes, toward its rear end, a fixing portion (11) that fixes the half model portion to a wind tunnel test apparatus side, and includes, within a housing, a torsional rigidity imparting unit.

Abstract: Monitor-guide-tube fixing sections are fixed to portions on a core support plate side of a plurality of in-core monitor guide tubes disposed in a reactor vessel. The monitor-guide-tube fixing sections are fixed to the core support plate disposed in the reactor vessel to fix the in-core monitor guide tubes to the core support plate. This makes it possible to realize improvement of rigidity of the fixed sections of the in-core monitor guide tubes. A tie plate is fixed to the in-core monitor guide tubes. The in-core monitor guide tubes are coupled by the tie plate. This makes it possible to realize improvement of rigidity of the entire in-core monitor guide tubes. As a result, it is possible to realize vibration damping for the in-core monitor guide tubes.

Abstract: A semiconductor pressure sensor according to the invention comprises a first semiconductor substrate and a second semiconductor substrate, disposed around the first substrate, so that signals obtained by the semiconductor pressure sensor under static or differential pressure conditions can be properly corrected and both static and differential pressures can be detected accurately and reliably measured on the same semiconductor substrates. Another object of the invention is provide a semiconductor pressure sensor which utilizes a single substrate with an aperture, which acts as a pressure overload stop mechanism, and which does not suffer from any effects of diaphragm deformation as a result of possible pressure overload.
