Title: Ventilation of vertically placed tanks for nuclear power facility during its maintenance
Inventor: MASUBUCHI AKIRA
IPC: G21D1/00
Filed: 1990-05-29
Abstract: PURPOSE:To enable fully ventilation of a vertically placed tank without providing any temporary ventilation opening by supplying and exhausting air from a manhole of the vertically placed tank as well as from a roof nozzle of the tank, and also by keeping an inside of the tank at negative pressure. CONSTITUTION:Contaminated air inside a tank 1 goes through an exhaust duct 31 from a roof nozzle 12 and then is exhausted after hazardous substances such as radioactive substances and the like are removed by a main body of exhausting device 3. On the other hand, fresh air goes through an air supply duct 21 and is supplied into the tank 1 via a roof manhole 11, by an air supplying device 2. In this occasion, since exhaust amount of ventilation is always made to be larger than air supplying amount thereof, an inside of the tank 1 can be kept to be at negative pressure. Personnel access, and bringing in and out of materials required for maintenance of the tank 1, can be conducted through a side manhole 13 since the manhole is always opened.

Title: Two-dimensional tilt angle sensor
Inventor: NISHIHARA KAZUE
IPC: G01B7/30
Filed: 1987-06-02
Abstract: PURPOSE:To enable accurate measurement of a tilt angle along with a smaller size of a sensor, by utilizing changes in measurable electrostatic capacity at a high accuracy. CONSTITUTION:A strut 4 is mounted 2-D tiltably at the upper end of a support protrusion 2 on a support base 1 to fix a disc-shaped electrode plate 5 while an electrode plate 6 is mounted at the lower end of the strut 4 facing the electrode plate 5. The electrode plates 5 and 6 have a number of capacitors made up of split plate pieces 6a-6d about the strut 4 to be connected to an electrostatic capacity detection circuit. Based on a differential component of changes in the electrostatic capacity between the several plate pieces 6a-6d, the direction and displacement of 2-D tilting of the strut 4 with respect to the support base 1 are measured simultaneously. In other words, when the strut 4 is tilted in a desired direction, the electrostatic capacity increases or decreases following changes in a gap between the electrode plates 5 and 6 on both sides of a spherical bearing 3 in the tilting direction thereof and thus, the tilt of the strut 4 can be detected accurately by extracting changes in the electrostatic capacity as differential electrostatic capacity.
