Inventor: PEETAA ERUBUEKUYARU
IPC: F01D5/24
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To damp the vibration generated on a blade of a heat flow machine by forming the radii of a cutout part and a buffer wire in the direction of rotary axial line of the blade to be smaller than the radii in the radial direction. SOLUTION: A plurality of blades 2 are provided in a turbine disc 1 of a heat flow machine. The turbine disc 1 and the blades 2 have a common rotation axis line 3. A plurality of blades 2 are bound into a blade package by a buffer wire 4. A cutout part 5 is arranged in each blade 2 to store the buffer wire 4. The buffer wire 4 and the cutout part 5 have an elliptical cross section. Radii 6, 6' of the cutout part 5 and the buffer wire 4 in the direction of rotary axial line of the blades 2 are smaller than radii 7, 7' in the radial direction. A cross section of the blade 2 at a height of the cutout part 5 is larger than the circular buffer wire. Consequently, nominal stress of the blade 2 and stress of the cutout part are reduced, and this dampens the vibration generated on the blade 2.

Filed: 1988-10-24
Abstract: PURPOSE:To miniaturize an entire circuit by constituting a transformer circuit for inverter with an inverter transformer and a reactor connecting to its high voltage side in parallel. CONSTITUTION:In place of a series resonance circuit resonated to a high voltage system fundamental wave frequency, a reactor L1 with a low impedance is inserted and the reactor L1 and the inverter transformer TR3 form an inverter transformer circuit whose impedance is sufficiently lower than a capacitor C2 of an L2C2 series resonance circuit resonated at a frequency near the inverter output frequency with respect to a fundamental wave frequency. Moreover, a low voltage winding of a bias transformer TR4 is connected in series with an inverter side winding of the TR3 and a low voltage side output voltage E of an injection transformer TR1 is applied to the high voltage side winding of the bias winding TR4. Thus, since it is not required to provide a series resonance resonated to the high voltage system fundamental wave frequency, the miniaturization is realized.

Abstract: PROBLEM TO BE SOLVED: To provide the air bag device which has no directionality in the developing behavior of an air bag even when an inflator is employed, in which gas blow-out holes are provided at one end part of it. SOLUTION: As for the pressure of gas G which is blown out of gas blow-out holes 5 provided at one end part of a circular cylinder shaped hybrid type inflator 3, the closer place close to the gas-blow out holes 5 is more subjected to high pressure, and the further place separated from the gas blow-out holes 5 is less subjected to high pressure. However, as for the opening area of each through circular hole 12 provided for a partition plate 11, the closer to the gas blow-out holes 5 each hole is, the smaller the area of each hole is, and the further separated from the gas blow-out holes each hole is, the larger the area of each hole is.  Therefore, the amount of gas G blown out of each circular hole 12 close to the gas blow-out holes 5 to the outside of the housing 4 is almost identical to the amount of gas blown out of each circular hole 12 far from the blow-out holes 5 to the outside of the housing.
