January almost over! And the sun is all over the countryside. Some birds tend to believe it's spring! And tomorrow we have a family party, to celebrate the end of the examperiod for grandchildren.... and their parents! Found some interesting phenomena in application of PTC Thermistors , (but who is interested in private research on thermistors!). It seems that the increase in Mn in the basematerial will have an immediate effect on the Curie-or Nat-temperature of the microsensors made .
Op 14-01-10 belde R op. Hij wou kleine Pillen 1.5 mm of kleiner . Hoe dik? 0.6 was OK. En hoeveel mochten ze kosten? Méér als 0.2 per stuk... NAT 100 moesten het zijn. Moesten in een "Röhrchen" gaan....
Eou hierover terugkomen, maar sprak eerst van 5.000 of 10.000 dan van 50.000 en dan van 300.000 St !!!
