摘要:
This invention provides a method and an apparatus for controlling a polymerization reaction. The temperature difference between a target temperature, calculated from the degradation rate of a polymerization initiator, which varies as a function of temperature, and a polymerization reactor temperature is calculated. The difference in polymerization rate between a target polymerization rate previously set and a polymerization rate calculated from a measured heat release value at a certain time in the polymerization process is calculated. The temperature inside the reactor is finely adjusted on the basis of the temperature difference and the difference in polymerization rate.
摘要:
A method of manufacturing a picture tube shadow mask wherein a thin metal plate containing iron and nickel as major components is first etched to form a plurality of mask apertures, then, annealing of the metal plate is performed and, after being cooled in a reducing atmosphere, a darkened oxide layer is formed on the surface of the annealed metal plate by subjecting the metal plate at first to a relatively weak oxidizing steam atmosphere and then to a relatively strong oxidizing steam atmosphere.

An automatic wire end arranging system includes a wire holder for holding one ends of the wires, a wire feed device for feeding the wire ends one by one from the wire holder, and a transport device for transporting each wire end from the wire feed device to an arranging device. The arranging device includes a fixture having a plurality of parallel receptive sections, and a table mounted adjacent to the fixture and having a slit, a probe device operable to make electrical contact with the wire end, fed to the table by the transport device, to feed a probe signal, a first drive device operable to move the table, a second drive device operable to bring the wire end on the table into alignment with the slit, and a third drive device operable to urge the wire end, disposed in alignment with the slit, into a selected one of the receptive sections through the slit. A control device, to which the other ends of the wires are electrically connected, is responsive to the probe signal to operate the first drive device to move the table, thereby bringing the slit into alignment with the selected receptive sections corresponding to the probed wire. The control device is responsive to the probe signal to operate the second and third drive devices to bring the wire end into alignment with the slit and to urge the wire end into the selected receptive sections through the slit.
摘要:
A process for producing a highly expanded polyolefin insulated cable comprising the steps of feeding a compound of polyolefin, nucleating agent and volatile liquid to an extruder, heat extruding said compound through said extruder onto an inner conductor passing through said extruder to cover the outer periphery of said inner conductor thereby forming an insulation layer of highly expanded polyolefin foam having a foaming ratio in excess of 2.5 times (60% expansion degree) tightly adhered to said inner conductor.
