Patent DE-2165539-B2 (DE)
Title: Double semiconductor hetero-diode laser - has gallium arsenide and gallium aluminium arsenide layers of opposite conductivity and specified thickness
IPC: H01S5/323
Filed: 1971-12-30
Abstract: The laser forms an oscillator in a symmetrical waveguide. High energy electrons of a n-doped gallium arsenide layer are supplied via a n-doped gallium aluminium arsenide layer to a p-doped gallium arsenide layer. They are held there by an energy barrier to a p-doped gallium aluminium arsenide layer for an induced recombination. The active layer fo p-doped gallium arsenide has a given thickness related to the wavelength of the generated laser beam and a diference of the refractive index of the n-, or p-doped gallium arsenide layer. The thickness is also related to the identical refractive index of both gallium aluminium arsenide layers.

Patent DE-2226628-B2 (DE)
Title: Electric contact in protective gas atmos - contg carbon dioxide to prevent formation of electroconductive products during arcing
IPC: H01H51/28
Filed: 1972-05-31
Abstract: Electric contact working in a protective CO2 atmos. is made from such a material that the products of its combustion with oxygen derived from CO2 at the arcing temp. (>=1200 degrees C) are practically non-conducting or have very high electric resistance. Thus, gradual formation of a conductivity bridge is prevented. The non-conducting combustion products are rejected from the gap by the action of static charges so that no insulation or mechanical obstacles are formed. The breakthrough potential is higher than in the case of other gases because CO2 has no ion-forming tendency. Used of CO2 as a protective gas is technically simple and cheap.
Patent DE-2234229-B2 (DE)
Title: Rapid action diaphragm type control valves - use of accelerating members increases speed and prevents fluid loss
IPC: B60T8/36
Filed: 1972-07-12
Abstract: Very rapid closure is achieved by the use of an accelerating member which may consist of an auxiliary diaphragm coaxial and in contact with the valve proper, but having a larger active area, or of a rod connecting entry and discharge valves of similar type. A simple compressed air system is shown with the first type of the discharge side. The valve diaphragm (18) is connected via a moulded ring (20) to the accelerator diaphragm (19), of larger diameter, the whole being spring loaded to the closed position. Use of the accelerating member prevents fluid loss during repetitive action as in anti-skid braking systems when entry (1) and discharge (3) ports might otherwise be connected for significant periods.

Abstract: PURPOSE:To enable a gas turbine to speed up to a rated speed maintaining a stable combustion even if a combustion gas compressor exists as a load by controlling the engine speed harmoniously with the amount of fuel inputted in the gas turbine at the stating time. CONSTITUTION:An engine speed setting signal needed at the starting time of a gas turbine 2 is obtained based on the first fuel control signal, which is sent from a starting fuel controller and which is equivalent to igniting, warming up, and engine speed raising at the starting time of a shaft. Further, the opening of a steam governor 10 is controlled on the basis of a steam governor opening degree setting value signal, at the starting time and during speedup, which is obtainable by comparing an engine speed setting value signal and a shaft speed signal. Hence, by providing a means to perform an engine speed setting harmoniously with the amount of fuel inputted in the gas turbine 2 at the starting time, that is the first fuel control signal, the load portion of a fuel gas compressor 15 is shared by a steam turbine 4 from the starting time, which is the starting of the shaft, until it reaches the rated engine speed so as to enable the gas turbine 2 to speed up to the rated engine speed stably.

Abstract: PURPOSE:To completely eliminate impossible decipherment due to construction of character by constructing a mask for laser marking of a metal layer formed patternlikely on a translucent glass base and an oxidized metal layer coated thereon. CONSTITUTION:A light shielding part 2 of a mask 3 for laser marking is constructed of a Cr layer 2a formed patternlikely with 2,000Angstrom  thickness on a main surface of a lithographic glass base 1 which is translucent for laser light, and a chrome oxide layer 2b covering the exposed surface. Accordingly, when the mask 3 is used, the area of the glass base 1 is reduced remarkably as compared to the conventional device, the diffraction and dispersion of laser light are reduced remarkably. Therefore, a distinct pattern is obtd. and damages of the base surface due to scratch are prevented. By this method, conventional defect, i.e. impossibility of decipherment due to constriction of characters is eliminated completely.
