Title: Thyristor with four alternating conductivity zones - has low depod or naturally conductivity intermediate zones
Inventor: GERLACH WILLI PROF DR
IPC: H01L29/744
Filed: 1974-12-23
Abstract: The thyristor is primarily intended for improving the switching possibilities and preventing undesirable breakdowns, without reducing considerably its current feed surface. Between the thyristor control base zone (5) and the adjacent outer emitter zone (3) is provided an intermediate zone (9) which is lowly doped in relation to the adjacent regions of the two zones, or even naturally conductive. Preferably the breakdown voltage of the structure formed by the emitter zone, the intermediate zone and the control base zone is between 30 and 150V. The control base zone may directly contacted by the control electrode (6). The control base zone is typically produced by impurities diffusion, the thickness of the impurity locations being adjusted by material removing.

Title: Dead weight pressure relief valve - has vibration of valve head damped by rotary motion imparted by spiral groove
Inventor: LANG HERMANN ING GRAD
IPC: F16K17/12
Filed: 1975-09-29
Abstract: The dead weight pressure relief valve (1) has a valve head (2) co-operating with a seat (3). The valve head (2) is guided by a central bolt (4) fitting in a bore (5).
