Title: Semiconductor varactor with high capacitance per unit area - has high barrier layer capacitance achieved by means of high doping
Inventor: BASSE PAUL-WERNER V DIPL ING
IPC: H01L27/108
Filed: 1976-05-20
Abstract: The metal-oxide-silicon semiconductor varactor device has a higher capacitance/unit area, through doping the semiconductor substrate in the region of the varactor, than in the remaining area. The second electrode (SE2) of a transistor (AT) is formed into the same substrate as the varactor. An inversion layer (V) is formed in the surface of the substrate when a potential is applied to the insulated metallisation (LB). The varactor capacitance is a combination of the electrode/inversion layer capacitance and the inversion layer/substrate capacitance (barrier layer capacitance). By increasing the doping of the substrate area below the varactor electrode (SE3), thus reducing the depth of the space-charge zone (RZ), the barrier layer capacitance is increased and with it the total varactor capacitance.

Title: Gas-cooled reactor shutdown heat removed from top reflector - by coolant esp. in natural circulation between reflector blocks
Inventor: LOIMANN EUGEN ING GRAD
IPC: G21C15/10
Filed: 1976-05-28
Abstract: A method of removing the decay heat (shutdown heat) from a nuclear reactor, esp. a gas-cooled reactor, consists of removing heat from the top reflector by means of coolant flowing through the top reflector, which itself acts as the heat exchanger. The flow of coolant through the top reflector pref. takes place by natural circulation. The coolant may be permanently located inside the top reflector or may be introduced into it when an emergency occurs. In the extreme hypothetical case, in which natural circulation through the core is no longer sufficient to remove the decay heat, e.g. when the pressure of primary coolant falls below 10 bars, the decay heat can only be removed by its radiation into the top reflector. The method enables the top reflector to be continuously cooled in such a condition.

Filed: 1976-09-23
Abstract: Procedure for producing packings esp. cigarette packets from cut outs by which the cut outs in a notched arrangement are separated essentially without waste from a band or a large sheet of packing material.
