  • Methods for tritium labeling
    Patent number: 5186868
    Abstract: Reagents and processes for reductively introducing deuterium or tritium into organic molecules are described. The reagents are deuterium or tritium analogs of trialkyl boranes, borane or alkali metal aluminum hydrides. The process involves forming these reagents in situ from alkali metal tritides or deuterides.

  • Platen for use in thermal printer
    Patent number: 4839667
    Abstract: A platen for use in thermal printer of a type designed to effect a printing with the use of at least one thermal print head for printing on a recording medium positioned between the platen and the thermal print head, which platen comprises a generally elongated elastic body having an exterior surface adapted to be brought into contact with the heating elements of the thermal print head assembly with at least the recording medium intervening therebetween, and a layer of porous material lined on the exterior surface of the elastic body and having a hardness greater than that of the elastic body and also having a thermal conductivity lower than that of the elastic body. The thermal conductivity and the porosity of the layer of porous material may be within the range of 0.05 to 0.10 Kcal/m.sup.2 .multidot.hr.multidot..degree.C. and within the range of 50 to 95%, respectively.
