    摘要: An actual ignition timing detecting device for use with a simultaneous ignition engine in which two cylinders are actually ignited in an alternate manner by simultaneously applying an ignition pulses generated in inverse polarities between the two terminals of an ignition coil. The actual ignition timing of the two cylinders can be detected from the rise and fall of a pulse signal, which rises at the misfire timing and falls at the actual ignition timing, by detecting the ignition pulses of one of the cylinders and by forming that pulse signal at all times in accordance with the difference in waveform between the actual ignition and misfire pulses of the ignition pulses detected.

    摘要: A porous carbon sheet having excellent physical properties is obtained by dispersing oxidized pitch fibers in a liquid containing at least one wetting agent having at least one hydroxyl group and a boiling point of not less than 150.degree. C, subsequently shaping the resultant dispersion in the form of a sheet, heating the sheet thus obtained at temperatures in the range of from 50 to 300.degree. C and thereafter, carbonizing the sheet in a nonoxidizing atmosphere. The oxidized pitch fibers contain 45 - 90% by weight of nitrobenzene insolubles and 55 - 90% by weight of fixed carbon and will not flow through a nozzle of 1 mm in diameter under a load of 10 Kg/cm.sup.2 at temperatures of not more than 300.degree. C. The pitch fiber has a diameter in the range of 5 to 100 .mu. and a fiber length/fiber diameter ratio of not less than 2.
