    摘要: Blast furnace coke containing low grade coal in a high blending ratio is manufactured by a method which comprises blending not less than 60% of a blended coal having an adjusted total moisture content of not more than 4% with not more than 40% of briquettes and carbonizing the resultant mixture.The blended coal consists essentially of not less than 80% of coking coal and not more than 20% of low grade coal. When coking coal of a kind which has its coking property segregated according to its grain size distribution is pulverized and classified by sifting and the portion of fine particles is used as mixed with the coking coal, the blending ratio of the low grade coal in the blended coal can be increased to up to 35%. The briquettes consist essentially of not less than 10% of coking coal and not more than 90% of low grade coal.

    摘要: An input pen assembly is provided which selectively cooperates with the screen of a cathode ray tube of a CRT display and the tablet of a tablet input device. The assembly automatically activates either one of the CRT display and the tablet input device in response to a change in the magnitude of a pressure applied by the pen against the screen of the CRT or the tablet. The input pen assembly includes an electrode which has its one end projecting forwardly of the front end of a casing and which is used for detecting a signal from the tablet. The electrode is formed with a through-opening which defines a light transmission path for a signal from the CRT display. Additionally the input pen assembly includes a spring which resiliently biases the electrode so that its front end projects forwardly of the front end of the casing, and a movable member which is disposed for movement with the electrode when the latter is retracted against the resilience of the spring. The movable member is movable between a first position corresponding to an initial position of the electrode where no pressure is applied thereto, a second position corresponding to a position assumed by the electrode when a given pressure is applied thereto as it is brought into abutment against the tablet, and a third position corresponding to a position assumed by the electrode as an increased pressure is applied thereto when it is brought into abutment against the screen of a cathode ray tube. Two of the three positions are associated with position detectors for detecting the extant position of the movable member. A logical combination of output signals from these position detectors provides a determination as to the position assumed by the electrode, thereby selectively activating the tablet input device or the CRT display.

    摘要: A capacitively coupled tablet for use with a probe comprises two sets of conductors spaced apart along coordinate axes to form a matrix, and an overlay disposed above the conductors and forming a plurality of key segments associated with the individual points of intersection of the matrix. A plurality of isolated electrode plates are disposed between the sets of conductors and the overlay at positions corresponding to each of the key segments, the electrode plates each being formed of a conductive material and having a size commensurate with the key segment. When a probe is applied against a particular key segment from over the overlay, the probe is capacitively coupled with selected conductors of the respective sets through the electrode plates.
