    摘要: A method for cooling hot reduced iron briquettes at low cost without degrading the strength is provided. The method includes a primary cooling step of cooling the hot reduced iron briquettes by steam at a cooling rate of 4.0° C./s or less, a secondary cooling step of cooling the reduced iron briquettes by steam and sprayed water at a cooling rate of 4.0° C./s or less, and a final cooling step of cooling the reduced iron briquettes by sprayed water at a cooling rate of 3.5° C./s or more to a temperature in a final product temperature range. The steam generated by evaporation of sprayed water during the final cooling step is used in the primary and/or secondary cooling step.

    摘要: A variable valve device of the invention has a structure in which, as connecting means for connecting a movable cam 22 located in an outer periphery of an outer camshaft 17a and an inner camshaft 17b located inside the outer camshaft 17a, there are provided a pin-like member 24 that is movably inserted so as to penetrate the movable cam 22, the outer camshaft 17a and the inner camshaft 17b along a diametrical direction of a shaft member 17 that is formed by turnably encasing the inner camshaft 17b in the outer camshaft 17a, and an escape-preventing portion 50 disposed in the end portion of the pin-like member 24. The movable cam 22 and the inner camshaft 17b are thus connected together while preventing large press-fit load and axial force from acting on components.

    摘要: A distributed data processing system is provided in which two computers, each running under a different operating system, are coupled so that jobs initiated by a first one of the computers can be executed on a second computer by using the resources of the second computer. This enables the user of the first computer to use the second computer under the environment of the first computer. The first computer acts as the interface between the user and the data processing system. Service programs running on the system can handle or provide for input/output operations during the execution of jobs on the second computer so that the jobs seem to the user of the first computer to be executed on the first computer. The system has means for creating a dummy file in the file system of one operating system which is used as a place holder for a corresponding file in a storage device attached to the other operating system, and accessed by programs controlled by that other operating system.

    摘要: A package is disclosed which includes an enclosed article, and a thermally shrinkable, synthetic resin film enclosing the article and having opposite, first and second edge portions, the first edge portion being superimposed on and sealed to the second edge portion to form a sealed, overlap portion, the film having perforations arranged in a row in at least one of the first and second edge portions and a coating of a seal-preventive agent provided in part of the overlap portion for weakening the seal in the overlap portion.
