The compensating Hall element H1 faces a compensating surface 6 where the gap G1 is kept constant.  A bias voltage is changed and set so that a difference ΔE between the output voltage of the compensating Hall element HE1 and a reference voltage E1 from a reference voltage source becomes zero, and it is given to the displacement detecting Hall element HE2. Thereby, the displacement detecting Hall element HE2 can obtain an accurate output voltage in response to the amount of the angular displacement of the piece to be detected 4, regardless of temperature changes.

Title: Method and device for detecting exfoliation in composite structure
Inventor: GO CHISHIN
IPC: G01M11/00
Filed: 2000-08-15
Abstract: PROBLEM TO BE SOLVED: To efficiently and highly accurately monitor the adhesion state between structure parts in a composite structure at all times. SOLUTION: FRP 3, which are reinforcing materials, are glued and fixed to concrete 1 by an adhesive 5. An optical fiber 7 is underlaid in the surface of the concrete 1 facing the adhesive 5 and the surface of the FRP 3 on the opposite side to the adhesive 5. By making pulse light P outputted from a distortion measuring device 9 incident onto the optical fiber 7 and analyzing the frequency distribution of Brillouin scattering light, which is the reflected light of the pulse light P, the distortion of the optical fiber 7 at a predetermined longitudinal location is measured. The distortion measurement is performed at the same locations in the underlaid regions H of the adhesion parts of the optical fiber 7 to the concrete 1 and the FRP 3.  In the case that the difference between the measured values exceeds a predetermined value, it is determined that the adhesion state between the concrete 1 and the FRP 3 has failed, and exfoliation is detected.

Title: Pressure control device
Inventor: NAKAMURA YASUHIRO
IPC: F16K17/30
Filed: 2000-08-17
Abstract: PROBLEM TO BE SOLVED: To improve the operability in the manual rotation of a spindle for adjusting the compression quantity of a pressure setting spring. SOLUTION: In this pressure control device 11, a manual operation handle 70 is moved up to a manually operating position, whereby the spring force of the pressure setting spring 36 of a pressure set part 17 can be manually adjusted. In the adjustment of the spring force of the pressure setting spring 36, a lock pin 68 is axially moved to fit the fitting part 68b of the lock pin 68 to the engagement hole 69a of an engagement groove 69. According to this, the lock pin 68 is integrally connected to the manual operation handle 70 to retain the manual operation handle 70 in the manually operating position. Therefore, it is not necessary to retain the manually operating handle 70 in the lifted state against the spring force of a clutch spring 65.  The spring force of the pressure setting spring 46 can be thus easily adjusted only by rotating the manually operating handle 70 retained in the manually operating position by the lock pin 68, and the labor for the manual adjusting work can also be reduced.

Title: Water-proof connector
Inventor: KIHIRA MUNEJI
IPC: H01R13/52
Filed: 2000-08-23
Abstract: PROBLEM TO BE SOLVED: To prevent buckling of a rubber ring, and to reduce insertion resistance in engagement with a mating side connector housing. SOLUTION: In this connector, the mating side connector housing 40 contacts the front end of the rubber ring 20, when a cylindrical part 15 is engaged with the mating side connector housing 40. Since a front end side of the rubber ring 20 is fixed to an engagement wall 23 to be prevented from being shifted toward a base end side of the cylindrical part 15, the whole rubber ring 20 is precluded from being compression-deformed even when pushed by the mating side connector housing 40. When the engagement moves forward, an intermediate portion of the rubber ring 20 is tensioned by the housing 40, the rubber ring 20 is elongated, a wall thickness is thinned thereby, and the engagement resistance is reduced to allow smooth engaging work.
