Title: Rotor blade for gas turbine
Inventor: SHIMAMOTO YOSHIHARU
IPC: F01D5/18
Filed: 1979-02-28
Abstract: PURPOSE: To cool the rotor blade of a gas-turbine efficiently with a relatively small amount of cooling liquid, by providing choking structures for reduction of the sectional area of passage locally in a plurality of cooling-liquid passages extended from the root portion to the top portion of the rotor blade body.  
     CONSTITUTION: When cooling liquid is introduced into coolant passages 13 from cooling-liquid supply port 14 in the state that rotor blade body 11 and blade base 12 are rotated together, cooling liquid flows from the root portion toward the top of blade 11 and finally discharged to the outside of blade 11. Here, in coolant passages 13, there are provided a plurality of choking structures 15, so that cooling liquid is urged in the direction of arrow Q on the opposite sides of choking structures 15 by the function of Corioli's force. Therefore, cooling liquid is issued to the next section through aperture 17 by the centrifugal force P after it is stagnated for a while in front of each choking structure 15. By thus arranging choking structures having such a function at appropriate intervals, it is enabled to cool the rotor blade uniformly.

Title: Welded bellows
Inventor: SUZUKI KAZUO
IPC: F16J3/04
Filed: 1982-02-19
Abstract: PURPOSE:To reduce stress generated near the flange end surface and to enlarge fatigue strength by disposing shell-like rings for peripherally covering the vicin- ity of each welding portion in the vicinity of each welding portion of the outer peripheral portion and the inner peripheral portion of a welded bellows near the end surface of a flange. CONSTITUTION:Shell-like rings 5, 6 are not united with a welded bellows, but adapted to cover respective welding portions 3 of the outer peripheral portion and the inner peripheral portion of the welded bellows through each gap, so that a certain fixed displacement such that a bellows plate 2 and the shell-like rings 5, 6 contact one another is kept without increasing a notch coefficient beta of the welded bellows itself. Therefore, the generated stress can be kept constant with less than such displacement. Since the shell-like rings 5, 6 are disposed among several convex portions from the end surface of a flange 1, if there is displacement orthogonal to the axis, stress generated on the flange end surface can be reduced.

Abstract: PURPOSE:To decrease the disturbance onto an FM audio signal by providing a control circuit increasing a frequency of a carrier signal of an FM video signal at audio exclusive mode so as to widen the frequency difference between the FM video signal and the FM audio signal at the audio exclusive mode. CONSTITUTION:A low frequency FM audio signal is recorded to an audio recording part 14a being a deep layer of a tape 10, a high frequency FM video signal is recorded to a video recording part 14b being the surface layer and the carrier frequency of the FM video signal even at the recording mode for the FM audio signal only.

Abstract: PURPOSE:To prevent the horizontal swing of a ceiling fan, by symmetrically inclining the vanes of the wind-revolved wind direction changing vane assembly of the ceiling fan with regard to a vertical plane containing the axis of the fan, to balance the wind pressure which acts on the vanes. CONSTITUTION:The wind direction changing vane assembly 8 of a ceiling fan is divided into two groups as to a horizontal line X intersecting the axis of the fan so that a plurality of vanes 9 are juxtaposed in parallel with the horizontal line X at one side of the vane assembly and inclined in the same direction and another plurality of vanes 9 are juxtaposed at the other side of the vane assembly symmetrically to those at the former side with regard to the vertical plane containing the horizontal line X. The forces which act to the wind direction changing vane assembly 8 are balanced to each other because the vanes 9, 9 are symmetrically located at both the sides of the assembly. As a result, the vane assembly 8 is not inclined by the forces. For that reason, the vane assembly 8 is stably rotated.
