Abstract

1445463 Resistors NIPPONDENSO CO Ltd and TOYOTA CHUO KENKYUSHO KK 19 Oct 1973 [1 Nov 1972] 48914/73 Heading C1M Resistors for ignition plugs consist of a glass and a respective component comprising by weight 4 to 22% bismuth oxide, 70À2 to 95% tin oxide and 0À8 to 9À6% antimony oxide. The glass is preferably borosilicate glass and is in an amount of 10 to 60% of the total weight of the resistor. The antimony oxide may be Sb 2 O 3 or Sb 2 O 4 and the tin oxide SnO or SnO 2 .
