Filed: 1989-02-22
Abstract: The controller (13) of the medical device is embodied with two channels, the components being present in an at least two-fold embodiment. For technical safety reasons, the input device (29) of the controller permits only a limited variation of data. A single-channel programming unit (21), which can be a personal computer, serves to change the programming of the controller (13). The data are freely programmable in this programming unit until the entire data record is produced, which is then subsequently transmitted to the controller (13). For the purpose of monitoring the correctness of the transmission, associated data or the corresponding CRC sums are simultaneously displayed, by pressing a key (28a), on the display devices (19) and (27) of the controller (13) and programming unit (21) and compared by the user. Pressing the key (28a) for passing on the data serves simultaneously as acknowledgement of the correctness of the transmission. The interpreters integrated in the read-only memory form the prescribed application from the transmitted data. <IMAGE>

Patent DE-4108904-A1 (DE)
Inventor: HOELTZEL HORST
IPC: H02K1/18
Filed: 1991-03-19
Abstract: In the operation of large vertical synchronous machines, considerable radial and tangential forces occur. A new simple type of attachment between the stator laminate stack and the stator housing is intended to ensure, on the one hand, the radial mobility between the two and, on the other hand, the necessary rigidity of the structure. According to the invention, sliding rings (4) in welded-on guide rings (5) are arranged between the pressed segments (2, 3) and the stator intermediate walls (14), securing taking place by means of attachment screws (8) via sliding washers (9). In consequence, the radial mobility is ensured. In order to dissipate the corresponding tangential forces, broad, lateral, parallel guide surfaces (11) and a defined expansion joint (12) are arranged on the dovetail-shaped guide rails (10). This arrangement leads to a simple structure and reliably prevents deformation of the laminate stack with the maximum temperature difference between the stator laminate stack (1) and the machine housing. This type of attachment is suitable, in particular, for large hydroelectric generators. <IMAGE>

Title: Structured superconducting conductor strips - formed by epitaxial growth on suitable substrate
Inventor: COPETTI CARLO
IPC: H01L23/498
Filed: 1991-06-24
Abstract: Mfr. of structured conducting strips comprising high-temp. superconductor (HTSC) films. A masking film is deposited on regions of a surface scheduled for the HTSC strips, on a substrate which is suitable for single-crystal growth of the HTSC strips. An inhibitor dopant is then evaporated over the entire substrate surface, and is lifted off from the regions scheduled for the conducting strips by lift-off of the masking layer. After subsequent deposition of the HTSC film on the substrate, with simultaneous or subsequent annealing of the HTSC on the doped substrate surface, an insulating area is formed by the diffusion of the dopant and the superconducting strips are formed by epitaxial growth on the undoped substrate areas. After depositing the masking layer (3) on the substrate surface regions (2) scheduled for the superconducting strips, the mask-free substrate regions (4) are removed by etching until the height of the masked regions (2) is increased in relation to the mask-free regions (4). This results in the HTSC strips, which are deposited after evapn. of the inhibitor layer (5) and subsequent lift-off of the mask and are formed by epitaxial growth, running on the heightened substrate surface (2) insulated from the doped substrate regions (4) carrying the insulator layer (6). A structured conductor strip is also claimed, based on the above, wherein the substrate consists of a material suitable for single-crystal growth of the superconducting strips (7), with elevated regions formed from the regions of the substrate which carry the superconducting strips (7). Pref. YBa2Cu3O7-x is used as the HTSC. The mask-free substrate regions are removed by ion-beam etching. The substrate is strontium titanate, lanthanum aluminate or yttria-stabilised zirconia. ADVANTAGE - The superconducting properties of the conducting strips are not impaired during the mfg. process for the HTSC structures.
