Title: Clock-pulse train monitoring circuit - compares input clock pulse train pattern with stored control train pattern to detect differences
Inventor: DIETL RUDOLF
IPC: H04M3/24
Filed: 1978-09-28
Abstract: The monitoring circuit has a single test line (b) connected to the clock pulse output lines (A1, An), in order to detect faults in the time sequence of the pulse trains appearing on these lines. The pulse sequence on the test line is compared (Vg) with the time characteristics of the control signals of fixed format used for originally generating these pulses. If there is a difference in a characteristic (time at which a pulse or pulse interval occurs, a fault signal is transmitted (GD, GA, GZ). The system enables monitoring of clock pulse train on a single line, one which the actual pulse trains are fed to the components.

Patent DE-2902409-A1 (DE)
Inventor: SCHMIDT HEINZ
IPC: F16K15/02
Filed: 1979-01-23
Abstract: Such a device for preventing water hammer has a diaphragm (16) of flexible material which is clamped between the extension of a cover (10) and the shoulder (17) of a bush (18) and the free edge of which lies between a valve seating surface (15) of the bush (18) and the conical surface (45) of a back-up ring (44) loaded by a spring (46). The water flowing in via an inlet passage (2) flows via an opening (3) past a noise-damping hose piece (5), along the valve seating surface (15) and into the housing passage (32). The back-up ring (44) prevents the wear and deformation of the diaphragm (16) since, as it is lifted off from the valve seating surface (15), it slides on the conical surface (45) of the back-up ring (44) without risk of damage.   <IMAGE>

Abstract: This method consists in providing a region between the emitter- and base zone whose doping concentration is small compared with that of the neighbouring emitter and base zones. The thyristor structure has an N+ emitter zone (1) and a control base P-zone (2). Between these zones is a narrow I-zone (3) with a considerably lower doping concentration (Nd+(3)) compared with the concentrations (Na-(2),Nd+(1)) of the P- and N+ zones. The control base P-zone concentration is in the region of 10 power 16 to 10 power 17 per c.c. This invention aims at producing a thyristor base-emitter junction whose emitter efficiency increases sharply at a defined current flow.
