Title: Pushbutton telephone with automatic re-dialling circuit - is powered by capacitor charged from line only during dialling
Inventor: NEMECSEK FERENC DIPL ING
IPC: H04M1/31
Filed: 1979-09-11
Abstract: A push button (T) telephone has a circuit (WG) stores the digits and transmits them to the line (a,b) via a dialling relay (USI). The number can be re-dialled by pressing a single button. Usually the first digit is a local code and one waits for tone before dialling the remainder. The duration of this pause is stored by the circuit (WG) and reproduced when re-dialling. Power (U,O) for the circuit (WG) is drawn from a capacitor (C2) which is charged from the line, via a transistor (T2), only during dialling. The transistor (T2) is driven by a second transistor (T3) which is driven by a contact (t), common to all the digit buttons. A relay contact (USU) then changes over and maintains the supply while each digit is dialled, plus 800ms. During the pause, when re-dialling, the circuit (WG) turns on (P) a third transistor (T1) which keeps the capacitor (C2) charged, via a resistor (W1), until the next digit. Rectifier bridges (G1,2) make the circuit independent of line polarity.
Patent DE-2937993-A1 (DE)
Title: Silicon gate forming system for MOS transistor - uses laser beam to melt insulating layer over gate to prevent breakdown
Inventor: DEPPE HANS DR
IPC: H01L21/263
Filed: 1979-09-20
Abstract: The method of forming an MOS transistor using the silicon gate system, includes forming an oxide layer (2) on the silicon substrate (1) and on this, the silicon gate electrode structure (3). This is protected by a phosphorous doped silicon dioxide layer (4) and a conductive layer (7). To prevent breakdown at the gaps (5,6) each side of the gate within the conductive layer, a beam of radiation is directed onto the region. A 200 Watt C02 laser is used to melt the phosphorous doped layer so that the conductive layer becomes more rounded within the region improving the insulation. The pulsations of the radiation are in the micro to nano second region. Alternative laser systems may be used, and temperatures between 400 and 500 degrees C. are reached in a hydrogen atmosphere. The melting effect causes the treated regions to slope outwards, and action can be improved by sloping the surfaces at an angle to the radiated beam.

Title: Stabilised astable multivibrator with enhancement FETs - has potential divider including one depletion and two enhancement FETs
Inventor: KUHLMANN JOACHIM DIPL PHYS
IPC: H03K3/354
Filed: 1980-07-19
Abstract: The astable multivibrator uses enhancement FETs with isolated gates, whose frequency is independent from variations due to the mfg. process which affects particularly the threshold voltage of enhancement FETs. This independence is achieved by connecting a potential divider consisting of three IG-FETs across the supply voltage. From these, a d.c. voltage proportional to the threshold voltage of the oscillating FETs is derived. Three FETs (Td13,Td14,Td15) form a potential divider across the supply (Udd,Uss) from which a d.c. potential proportional to the threshold voltage of the oscillating FETs (Te2,Te4) is derived and connected to their gates via enhancement FETs (Te5,Te8).
