    摘要: A so-called Ziegler catalyst composed of a titanium halide-containing solid ingredient and an organoaluminum compound for the polymerization of olefins can be imparted with greatly improved storage stability by first subjecting the catalytic composition to a pre polymerization treatment and then to a contacting treatment with carbon dioxide and/or carbon monoxide. The catalytic activity is almost unchanged even after storage of the stabilized catalyst for 90 days or longer in nitrogen gas. The stabilized catalyst can also be used advantageously in a continuous-process polymerization of propylene by continuously introducing the monomer carrying the catalyst owing to absence of blocking of the pipe line with the polymer formed in-line.

    摘要: A device for detecting errors of a plurality of electric parts which are built in electronic equipment has error detecting circuits in the form of relays. The relays are interconnected one-to-one to various electric parts which are the subject of error detection, while display circuits are interconnected one-to-one to the relays. Output signals of the relays are fed to a reporting circuit without the intermediary of the display circuits. When an electric part is free from an error and only a display circuit associated therewith has failed, no error signal is fed to the reporting circuit. Only when any of the electric parts has really failed, an error signal is delivered to the reporting circuit to cause the latter to take an adequate measure such as the interruption of power supply.
