Title: Process for preparing electroconductive sintered layers
Inventor: NOVTNY JOHANN DIPL ING
IPC: H01C17/06
Filed: 1988-03-31
Abstract: For thermal printheads, a row of closely adjacent, individually drivable resistance spots is used. The resistance spots consist of resistant paste printed onto the planar face of a ceramic plate and then sintered. In order to achieve smaller resistance spots of high accuracy, it would be desirable to be able to provide the front edge of a thin ceramic plate with the resistance spots. The invention specifies a process for this purpose. To this end, in essence, the as yet unfired substrate (1, 1') is sandwiched between two ceramic plates (10, 11), the surface (12) of the block (8) thus obtained is surface-ground, the block (8) is sintered, and the surface (12) is then printed with resistance paste, the block (8) is cut up, and the substrate (1, 1') obtained therefrom is sintered. The process is highly suitable for fabricating the active part of thermal printheads. <IMAGE>

Title: Heat denaturation for fresh biopsies
Inventor: SCHUBERT WERNER DR MED
IPC: G01N1/28
Filed: 1989-03-18
Abstract: Histological effects of a completed heat denaturation in the sense of complete stabilisation for organic specimens which have not yet been fixed, such as biopsies, in particular in the evaluation of frozen sections, which can be prepared from biopsies stabilised in the water vapour in a plastic bottle in a microwave apparatus in a few minutes are reported. Such biopsies such as organs acquire a higher quality for subsequent work in the laboratory in that, after the stabilisation, they now contain, with better cuttability, practically all the original substances such as proteins, fat, electrolytes and even by far the greater part of the original cell nuclear fluid/tissue fluid, which yields advantages, even after stated staining and suitable inclusion/covering of the specimen, not only for morphological microscopic investigations which yield rapid results but also for histochemistry.
