Title: Device for measuring bend in magnetic recording tape
Inventor: TANNO SHIGENORI
IPC: G11B5/84
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To dissolve dispersion in measurement by forming semicircular deflection on a magnetic recording tape and simultaneously rolling a measuring roller and a deflecting roller. SOLUTION: A bend is an index of linearity when the magnetic recording tape is placed on a flat surface, and is shown by a difference of heights on a position β between the position α and the position γ. A measuring base 12 whose base itself is provided with a tilt, and laser system width sensors are fitted to positions on three points α, β, γ being measuring means. The means causing the semicircular deflection 15 by deflecting the magnetic recording tape 11 on the downstream side closed position of the measuring roller 14 is constituted so as to form the semicircular deflection 15 by the exclusive deflecting roller 16. The deflecting roller 16 in such a constitution is placed first on the measuring base 12, and the magnetic recording tape 11 is placed on it, and a deflected shape is formed.  When the rollers 14, 16 with different weight are parted on the tilted measuring base 12 simultaneously, both roller are rotated without parting, and the measurement is performed precisely.

Title: Turbine exhaust steam sparger
Inventor: NAGAKUBO SHINICHIRO
IPC: G21C15/18
Filed: 1990-07-18
Abstract: PURPOSE:To stabilize the condensation of exhaust steam by selecting the whole opening area for jetting the exhaust steam so that the jetted steam has specified weight flow density. CONSTITUTION:For example, the whole opening area is lessened by reducing the number of large diameter openings 3c in the lower portion of a cylindrical body 3a of a sparger 3 or limiting the opening to only one kind of openings 3d having about 10-15mm diameter. Generally, while steam condensation is stabilized when weight flow density is at least about 40kg/m<2>.s, the weight flow density of blow-out steam can be set to about 40kg/m<2>.s - 80kg/m<2>.s by contracting the whole opening area in this way. Thus, the condensation and condensate of exhaust steam of a pump riving turbine is stabilized and a load generated in the sparger section in driving the turbine can be substantially reduced to improve the safety of a cooling system in the isolation of a nuclear reactor.
