Title: Four way pressure balanced valve - has balance control pressure arranged to regulate valve and hydraulic control valve
Inventor: BARTHOLOMAEUS REINER
IPC: F15B13/04
Filed: 1975-05-02
Abstract: The four way valve is combined with a two way pressure balance. For both directions of movement of the consumer, one control pressure for the pressure balance is taken off one consumer connection of the path valve. When the pressure balance is arranged in the outlet, either the pump pressure or the control pressure of the balance, forms the other control pressure. When the pressure balance is positioned in the inlet, the second control pressure is formed by the tank pressure of by the regulating pressure of the balance. The control pressure for the flow balance for both movement directions of the consumer is taken off the consumer connection of the path valve, and simultaneously forms the control pressure for a hydraulic control valve.

Title: Semiconductor film deposition on more highly doped substrate - by giving other sides non-doping mask and purging reactor periodically
Inventor: SPETH MANFRED DIPL PHYS
IPC: H01L21/205
Filed: 1975-10-24
Abstract: Prodn. of a semiconductor device involves the thermal deposition of a monocrystalline semiconductor film from a reaction gas on the surface of a more highly doped monocrystalline semi-conductor substrate disc, with precautions to prevent the dopant entering the film from the substrate. In the first stage, all the surface of the substrate, except one side, is masked completely with a pure, non-droping inorganic insulant or semiconductor deposited from the gas phase. Then the semiconductor film is deposited on the unmasked side in stages, the reactor being purged to remove the active substances of the reaction gas during each pause between stages. The mask prevents the dopant passing into the reaction gas. For example, a SiO2 and/or Si3N4 or semiconductor (Si) mask can be used. The substrate is doped with P, B and/or As in a conc. of min. 1019 cm-3, whilst the dopant concn. of the film is max. 1 x 1016, pref. 4 x 1015 cm-3. Pure H2 and/or inert gas is used for purging.
