  • Antenna device
    Patent number: 11984674
    Abstract: The antenna device A1 includes an antenna 1 configured to transmit and/or receive radio waves, and a dielectric elastomer drive element 2 including a dielectric elastomer layer 21 and a pair of electrode layers 22 sandwiching the dielectric elastomer layer 21. The dielectric elastomer drive element is capable of changing an antenna characteristic of the antenna 1. With such a configuration, the antenna device can be made smaller and lighter while improving its antenna characteristics.

  • Substituted benzimidazole fungicide
    Patent number: 4857541
    Abstract: A fungicide which is particularly effective against benomyl resistant fungi is selected from the group of fungicides represented by the formula: ##STR1## wherein R is C.sub.n H.sub.2n+1 and n is 1, 2, 3 or 6 or R is phenyl. The method comprises applying as a suspension an effective amount of the one or more fungicides selected from the formula to benomyl resistant fungi, such as benomyl resistant isolates of Botrytis cinerea.
