  • Publication number: 20120318732
    Abstract: The invention provides a sintered ethylene polymer filter that is free from molding unevenness or defects and has ultrafine and uniform filter pore diameters. An ethylene polymer composition including an ethylene polymer with a specific shape and specific properties and an antistatic agent with a specific form is used as a material for a sintered filter. According to such a composition, the ethylene polymer particles achieve enhanced fluidity when being placed into a sintering mold. Thus, the composition gives a sintered filter that has an ultrafine pore diameter and a narrow pore diameter distribution and is free from molding unevenness or defects.

  • Patent number: 5640055
    Abstract: A multiplex transmission system in a vehicle, for transmitting data indicating an on/off state of an ignition switch, includes first and second power distributing units receiving first and second signals over first and second signal lines, respectively, indicating the on/off state of the switch. The first power distributing unit controls a first load in accordance with the on/off state of the switch indicated by the first signal. The first power distributing unit provides a third signal to the second power distributing unit over a multiplex transmission line indicating the on/off state of the switch. When either the second signal or the third signal indicates that the switch is in an on state, the second power distributing unit controls the second load in accordance with the on state of the switch. When the second power distributing unit fails to receive the third signal, the second power distributing unit controls the second load in accordance with the on/off state indicated by the second signal.
