Title: Stationary blade of gas turbine
Inventor: SUENAGA KIYOSHI
IPC: F01D25/12
Filed: 1995-03-30
Abstract: PURPOSE: To prevent a blade part from the generation of large thermal stress therein by providing a supply groove for supplying steam to every other hole of a plurality of convection cooling holes in the outside shroud of the blade part and a recovery groove for recovering the steam supplied from the convection cooling holes and introducing the steam into the other adjacent convection cooling holes. CONSTITUTION: A supply groove 8 for supplying steam to every other hole of a plurality of convection cooling holes 5 is carved in the outside shroud 2 of a blade part 1. Also, a recovery groove 9a for recovering the steam supplied from the convection cooling holes 5 and introducing the steam into the other adjacent convection cooling holes 6 is provided in the inside shroud 2a of the blade part 1. Thus, the steam is supplied and recovered alternately through the adjacent convection cooling holes 5, 6 in the blade part 1, so that the distribution of temperature is uniformed and large thermal stress is not generated in the blade part 1 even if the temperature of the steam is raised by the convection cooling. Thus, the cycle efficiency can be improved in the high temperature steam after the recovery.

Title: Graphic information input system
Inventor: HOTTA TAKASHI
IPC: G06T11/60
Filed: 1987-03-27
Abstract: PURPOSE:To improve the efficiency of graphic processing operation by inputting the geometric shape of a graphic element and an information symbol indicating attribute information to a computer and reading the graphic element and attribute information out of the position relation between the both at the same time. CONSTITUTION:A graphic 1 consists of graphic elements 1a-1e and symbols 1a'-1e' indicating attribute information on mountains and forests or the like are described previously in respective closed curves. An automatic graphic reader 2 reads position information for the graphic elements 1a-1e and position coordinates and previously defined identification codes for the symbols 1a'-1e'. Those data are recorded on a magnetic tape 4. Then the computer 5 extracts the symbols 1a'-1e' from the magnetic tape 4 and retrieves closed curves 1a-1e which include them to give the identification codes that the symbols 1a'-1e' have. Thus, the graphic elements 1a-1e are registered in a memory corresponding to the attribute information on mountains and forests or the like automatically. Consequently, the graphic elements 1a-1e can be specified only by inputting the identification codes on a keyboard 7.

Namely, the shape of the dot 26a which is the closest to the light source 21 is a hexagon and the shape of the dots 26b-26e is an isosceles triangle. As the distance from the light source 21 becomes longer, the shape of the dot gets slender from the dot 26b to the dot 26e. As a result, the unevenness of brightness on the light dimming plate 23 is reasonably improved to be uniformized.
