摘要： A vibration-controlling bearing for controlling vibration developing in a rotary shaft supported in a housing of a rotary machine including a bearing member of a cylindrical shape interposed between an outer peripheral surface of the rotary shaft and an inner peripheral surface of the housing and spaced apart therefrom by respective gaps. A dynamic pressure is generated between an inner peripheral surface of the bearing member and the outer peripheral surface of the rotary shaft. Communicating ducts are formed in the bearing member for transmitting a portion of the dynamic pressure generated to a gap between the outer peripheral surface of the bearing member and the inner peripheral surface of the housing.

摘要： The invention is concerned with a sliding-type bearing suitable for use in high-speed rotary machines. The sliding-type bearing has a bearing surface provided with a lubricating oil groove at each of two portions thereof substantially 90.degree. spaced from the point to which the load exerted by the bearing is applied. A chamfer is formed in the portion of the bearing surface near one of the two lubricating oil grooves remoter from the point of the minimum bearing clearance which is determined by the direction of rotation of the shaft and the direction of application of the load by the rotary shaft. This chamfer permits the discharge of the heated lubricating oil to the outside of the bearing thereby to prevent the same from flowing into the point of the minimum bearing clearance.

摘要： Provided are a polymerization catalyst composition for ethylene oxide which can give polyethylene oxide having a molecular weight lower than that of the prior art and a relatively narrow molecular weight distribution, and a process for the production of polyethylene oxide by the use of the catalyst composition. The catalyst composition makes it possible to produce polyethylene oxide having a molecular weight ranging from about 20,000 to 200,000 through direct polymerization in a high yield with economic advantage, and is characterized by comprising an organoaluminum compound and at least one member selected from among alkali metal alkoxides and alkali metal hydroxides. According to the process, polyethylene oxide having a molecular weight failing within the above range can be produced by the use of the catalyst composition under the same polymerication conditions as those of the prior art.

摘要： A turbine meter comprising a casing of substantially hollow cylindrical shape installed within a conduit through which a fluid to be measured is flowing, an axle member supported within the casing and having an annular recess therearound; a longitudinal flow passage formed in the axle member, a plurality of discharge holes formed in the axle member to connect communicatively the annular recess and the flow passage, a supply pipe inserted into said conduit through the wall thereof and functioning to supply a pressurized fluid to said flow passage in the axle member, a vane wheel comprising a hub disposed around said annular recess with minute gaps therebetween and adapted to rotate in a substantially non-contacting state relative to the axle member and a plurality of vanes implantedly fixed at their root parts to the hub, said vane wheel being rotated by a portion of the fluid being measured which flows through the casing, and means for detecting the rotation of the vane wheel. The pressure of the pressurized fluid and the dimensions of said minute gaps are selected at values to cause forces acting on the vane wheel during rotation thereof and urging the vane wheel to undergo displacement in the thrust direction to be mutually cancelled, whereby the vane wheel rotates in a state of stable equilibrium.
