Patent DE-2065973-A1 (DE)
Title: Semiconductor device with ionic bombard- - ment stage during manufacture
IPC: H01L31/00
Filed: 1970-11-16
Abstract: Over a part of the surface of the semiconductor substrate a metal film is applied and this is bombarded selectively with ions from a gas discharge of an inert gas such as Ar or Kr so that atoms are implanted, due to the energy transmission, from one of the elements in the metal film into the semiconductor surface zone in the area desired. The intimate bond so formed may be an ohmic or a rectifying contact. A variety of substrate materials and doping elements in the metal film may be used to provide a variety of device types.

Title: Mine sensor system in flowing river - has locating ultrasonic echo sensor and alarm sensor generating magnetic field triggering signal when distorted by object
Inventor: KERBSTAT SIEGFRIED
IPC: F42B22/04
Filed: 1973-04-14
Abstract: The sensor system is used for mines when mining flowing rivers. The mines have a battery powered initiation system released by an object which reaches the vicinity of the sensing region of the mine. The sensor ensures tactical action of the mines of this kind under all circumstances. The circuit has passive and active signals receivers. A passive signal receiver in the form of alarm sensor transmits a signal for activating the active signal receiver, which is in the form of a locating sensor. The initiation signal is produced by this system. The passive signal receiver generates a magnetic field for producing a signal when the field is distorted by the arrival of an object. The locating sensor is an ultrasonic echo sensor with the integrating travelling time measurement device set at a fixed pulse sequence frequency.

Title: Pulse frequency to DC converter - has linear characteristic for wide frequency band
Inventor: GIELOW GUENTHER DIPL ING
IPC: H03K9/06
Filed: 1975-02-22
Abstract: An incoming pulse train is applied to a terminal to which a wave-shaping sequence of two monstable flip-flops is attached. The relatively noise-free pulses generated by these are used to reset a counter register which counts at a frequency dependent on a local crystal controlled oscillator, and which as a result repeatedly holds numbers corresponding to the frequency of the incoming pulse train. These numbers are converted by a digital-to-analogue converter to produce the required output via an amplifier at an output terminal. The network has a rapid response and can operate at low frequencies.
