Abstract: A steam turbine for use in a thermal or nuclear power plant includes moving blades of a rotor which vibrate as the rotor rotates, inducing an excessive stress in joints of connecting members for connecting the adjacent moving blades and blade portions of the moving blades and damaging the joints. The moving blades are formed so that a width of a gap between opposite end surfaces of first connecting members of adjacent blades along the direction of rotation of the rotor and a width of a gap between opposite end surfaces of second connecting members of the adjacent blades along a direction of rotation of the rotor are determined so as to make the second connecting members start coming into contact with each other at a rotating speed of the rotor higher than a rotating speed at which the first connecting members of the adjacent blades start come into contact with each other.

Abstract: An operator's cab structure for a construction machine, arranged to minimize the degree of lateral projection of a cab door on the outer side of a left enclosure section, for the purpose of securing a broader dwelling space within a cab. A side panel or wall portion which is provided in a left side enclosure section of a cab box is located in a receded position inward of outer marginal edges of a ceiling enclosure section. By this arrangement, an open door accommodating space is formed or defined on the rear side of the left side enclosure section by an outer surface of the side wall portion, lower surface of the ceiling enclosure section and rear surface of a center pillar. As a consequence, when the cab door is opened, it is received in the open door accommodating space to minimize the extent of lateral projection of the door on the outer side of the left enclosure section.

Abstract: A device of detecting collision of a vehicle for determining collision of a vehicle based on an acceleration from an acceleration detecting means for detecting a collision acceleration of the vehicle, the device including a collision force calculating means for calculating an estimated collision force caused in the vehicle in the collision based on the collision acceleration and a collision determining means for determining the collision based on the estimated collision force.

Abstract: A rope tension measuring apparatus for measuring rope tension of a plurality of main ropes that suspend an elevator car and a counterweight and adjustment quantities of tension adjusting springs for the main ropes. The apparatus comprises a portable measuring device comprising traveling-wave detector means directly attached to the elevator main rope for detecting a traveling wave that is generated by applying an instantaneous displacement to the main rope, traveling-wave passage velocity computing means for measuring the passage velocity of the traveling wave, rope tension computing means for computing the rope tension based on the passage velocity, spring adjustment quantity computing means for computing a spring adjustment quantity for the rope tension adjusting springs, and output means for outputting these computed results, based on the variation of passage velocities of the plurality of main ropes.

Abstract: An apparatus of stationary blade for an axial flow turbine includes a diverging flow channel for flowing an elastic fluid and stationary blades which are fixed at the diverging flow channel and are curved in perpendicular direction to the flow direction of the elastic fluid. The stationary blades form the same tangential lean angles at the leading edge and the trailing edge of the stationary blade corresponding to the flow direction of the elastic fluid, and an axial flow turbine has the apparatus of stationary blades thereof. The stationary blade distributes the fluid in the flow channel uniformly and, consequently, improves the efficiency of the flow.

Abstract: A turbomachine rotor arrangement is provided having a rotor wheel and blades thereon with a tie pin for interconnecting adjacent blades. A plurality of blades respectively define tie holes wherein the tie holes of adjacent blades are disposed with the radial heights of said holes being different and with the tie pin disposed in the tie holes so as to be acted upon by respective different amplitudes of vibration than said adjacent blades during rotation.

Abstract: A plurality of turbine buckets annularly arranged around a rotor are each provided with a ledge disposed at right angles to the outer surface of each bucket. Each ledge includes a leading end portion and a trailing end portion each formed therein with a vertical hole, leading and trailing end portions of the ledge of each turbine bucket extending in opposite directions on both sides of the bucket. There are provided cover pieces each interposed between ends of the adjacent two turbine buckets and formed on the upper surface with a plurality or cylindrical projections adapted to be loosely received in the vertical holes formed in the ledges of the adjacent two turbine buckets.

Abstract: A process for precipitating a crystalline diamine dicarboxylate which comprises dissolving the corresponding dicarboxylic acid in the aqueous liquid containing diamine dicarboxylate and adding the sufficient amount of the corresponding diamine to precipitate the desired product by neutralization.
