Low voltage dc to high voltage dc converter - regulator with minimium external magnetic field disturbance for space power system application
Power converter for ion thrustors using electronic gate controlled switches in two phase-shifted parallel inverters
Thin film photovoltaic solar energy converters of aluminum, gallium, arsenic, copper and selenium
Engineering developments for low voltage dc to dc converter-regulator with minimum external magnetic field disturbance
Photovoltaic solar energy converters discussing current technology in cells, their modules and mountings, concentrators and improvements
Compact motor mounted on a stationary base converts rotary to linear motion. The motor rotates a gear train assembly so that the end of an arm attached to the assembly moves in a linear path.
Two-core nonsaturating dc to dc converter provides high switching efficiency without producing large stray magnetic fields. It uses one core to provide positive feedback and the combination of the two cores for the transformer.
Auxiliary discharge thermionic energy converter - gas discharge processes, and plasma parameters
High-frequency dc-dc converter for ion thrustors using modular design and inductive energy pumping technique for conversion, regulation, and protection
RC network and ideal current negative immittance converter with unity gain used in obtaining RLC VOLTAGE transfer functions
Saturn booster recovery by means of drag balloon which converts to hot air balloon for final recovery
Computer program converts print image tape files into six dot Braille cells, enabling a blind computer programmer to monitor and evaluate data generated by his own programs. The Braille output is printed 8 lines per inch.
Parametric up-converter translates a broad band of signals to the fixed tuned input frequency of a maser. This modified maser can operate in the 1700-2300 Mc range, eliminating the need to duplicate equipment. It may be applied in communications and radio astronomy.
Assembly processor program converts symbolic programming language to machine language. This program translates symbolic codes into computer understandable instructions, assigns locations in storage for successive instructions, and computer locations from symbolic addresses.
Solid state, single-ended switching dc-to-dc converter electrically isolated a dc supply from the prime dc power service.
Magnetic tape recording and playback equipment converts television pictures, both black and white and color, from one scan rate to another. The equipment indexes color picture frames for retrieval electronically and can be used as a document storage and retrieval medium that is compatible with hard-copy printout machines.
Linearity and temperature stability of linear analog dc voltage-to-pulse width converter
Static dc to dc regulated converter using two-core output transformer
