Title: Rotor blade of steam turbine
Inventor: TAKAHASHI YOICHI
IPC: F01D5/16
Filed: 1991-10-08
Abstract: PURPOSE:To reduce vibration of a rotor blade at the time of operation of a turbine so as to prevent breakage of the rotor blade by implanting, in a blade groove, the rotor blade having circumferencial length of whose shroud ring with the its cross section of parallelogram shape in circumferencial direction is made larger than a theoretical pitch, and applying force to the rotor blade and twisting the blade part so as to form an annular blade train of the theoretical pitch. CONSTITUTION:A rotor blade 1 consists of a leg part 2 inserted in the blade groove of a rotor, a blade part 3 extending from the leg part 2, and a shroud ring 4 for covering the top end of the blade part 3. The leg part 2, the blade part 3, and the shroud ring 4 are respectively scraped out in one body. The leg part 2 of each rotor blade 1 the circumferencial direction cross sections of the shroud ring 4 and the leg part 2 of which are formed in a parallel-ogram shape, is inserted into a blade groove in order. The rotor blades 1 are installed at a prescribed pitch so as to form an annular blade train. When the leg part 2 of each rotor blade 1 is inserted into the blade groove so as to form the annular blade train, each blade part 3 is formed in its shape twisted. The shape of the rotor blade 1 is formed in such way that the circumferencial direction length of the shroud wheel 4 provided in the vicinity of the rotor blade 1 is increased more than a prescribed pitch. The matually adjacent rotor blade 1 are brought in contact with each other at their shroud rings 4 and leg plates 7, so as to support each other. It is thus possible to obtain damp effect of vibration.

Title: Manufacture of iii-v compound semiconductor single crystal
Inventor: SASAOKA CHIAKI
IPC: H01L21/205
Filed: 1987-10-16
Abstract: PURPOSE:To realize selectivity under a growth condition of a wide range by a method wherein a group III raw material containing one or two bonds of a group III metal and a halogen atom in its molecule is used. CONSTITUTION:In a metal organic molecule beam epitaxial method(MOMBE) where a substrate crystal placed inside a vacuum container is irradiated with a molecular beam of a group III organic metal and a molecular beam containing a group V atom and a III-V compound semiconductor single crystal is grown on said substrate crystal, the group III organic metal containing one or two bonds of a group III metal and a halogen atom in its molecule is used. The organic metal having one or two bonds of the group III metal and the halogen atom is transformed into a metal monohalide by thermal decomposition. Because this metal monohalide is not adsorbed onto SiO2, a polycrystal is not grown on a mask during a selective growth operation. Accordingly, it is possible to obtain selectivity even at a low temperature.
