摘要:
New gona-4,9(10)-dienes of formula I ##STR1## where R is alkyl of 1 to 3 carbon atoms and X is Cl, Br, F, N.sub.3, SCN, CN, OH, OR'(R'=alkyl), NH.sub.2, a substituted amino group or a heterocyclic compound including nitrogen in the ring. The compounds have valuable biological properties, especially hormonal and antihormonal effects, and can be used to advantage in pharmaceutical preparations for the treatment of endocrinopathies and for reproduction control in human beings and livestock.The invention also embraces a process for making the compounds by converting 3-methyoxy-13.beta.-R-gona-2,5(10)-diene-17.beta.-spiro-1',2'-oxiranes first to 17.beta.-hydroxy-17.alpha.-CH.sub.2 X-13.beta.-R-gon-5(10)-en-3-one, then to the 17.beta.-hydroxy-17.alpha.-CH.sub.2 X-13.beta.-R-gona-4,9(10)-diene-3-ones of formula I.

摘要:
A field device for determining or monitoring a physical or chemical process variable in automation technology, comprising at least one transmitting/receiving element, wherein an FPGA component is provided, the transmitting/receiving element is configured in the form of a spiral from existing internal connecting lines of the FPGA component, and the spiral of the transmitting/receiving element transmits data inductively to a second transmitting/receiving element in the form of a spiral.
摘要:
The apparatus enables the automated testing, calibration and characterization of test adapters for semiconductor devices. A holder for the test adapter can be rotated in a defined manner. At least one probe head is provided which can be adjusted radially with respect to the holder. The probe head has two or more contact pins whose spacing distance is adjustable.
摘要:
A system for the flexible configuration of function modules. The system includes the following components a plurality of logic cells in a fixedly wired FPGA/standard ASIC structure, wherein the logic cells are so configurable by means of configuration registers, that they execute basic logic functions; a switch matrix having a plurality of memory cells, via which different logical connections of the logic cells in defined complex connections are configurable by means of the configuration registers; and a control unit, which partially dynamically so configures the logic cells and the switch matrix via an internal bus and via the configuration registers by means of a configuration bit stream, that the fixedly wired FPGA/ASIC structure behaves functionally as a partially dynamically reconfigurable logic chip.
