Title: Rotor blade of turbine
Inventor: HIGASHIMORI HIROTAKA
IPC: F01D5/04
Filed: 2002-06-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a rotor blade of a turbine for preventing separation of a flow at a trailing edge of the rotor blade and preventing increase of flow losses.  <P>SOLUTION: A deflection angle of a blade surface on the downstream side of a maximum blade thickness part 4 is reduced by forming a trailing edge 3 of a rotor blade 2 in a deviating manner so as to be brought closer to an extension 6a side of a negative pressure surface 6 on the upstream side of a maximum blade thickness part 4 from a center line 8 of the blade thickness. Since the trailing edge 3 of the rotor blade 2 is thus formed, the deflection angle at the trailing edge part 5 is not abruptly increased. Therefore, no abruptly accelerating portion 11 or abruptly decelerating portion 12 is formed in the flow velocity 9 on the negative pressure surface of a main stream, and flow separation at the trailing edge part 5 is prevented. Flow losses are reduced, and the turbine efficiency is improved thereby.  <P>COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a method for etching structures into ferroelectric materials. SOLUTION: A single layer of ions is implanted into a film surface and the material between the surface and the ion implantation layer is etched away without annealing the substrate. Electronic damage and crystalline damage of high levels are formed with single ion implantation with sufficient energy. Although the fact that the crystalline damage increases an etch rate of the ferroelectric material is publicly known, the inventors have discovered that the electronic damage increases the etch rate of the material. Damaged LiNbO3 has an etch rate much faster than undamaged LiNbO3 and an annealing process is not necessary for forming an etch stopping layer.
