Title: Centrifugal compressor
Inventor: HATTORI SHIRO
IPC: F04D29/44
Filed: 1985-10-29
Abstract: PURPOSE:To improve compression efficiency by accelerating slow speed gas near a wall surface by making gas, introduced from a high pressure side through a gas blowout hole arranged at a diffuser inlet, blow out in the direction of a main gas stream. CONSTITUTION:A gas blowout hole 10 is arranged as near to an impeller outlet of the inner diameter part of a diffuser wall on the side of a wall surface 8 as possible.

Abstract: PURPOSE:To obtain mechanical and thermal stability and to improve sensitivity by forming a magnetostriction layer of magnetic material containing one or more kinds of metallic sulfide resulting from the reaction of nickel, a metal easier to react with sulfur than nickel and impurities. CONSTITUTION:This strain gauge is constituted of a driven member 1, a magnetostriction layer 2 and a detecting coil 3.
