Soldering and welding techniques are used to connect a coaxial cable to a printed circuit board. This device aids reliability control of equipment as standard connectors are bulky and heavy.
For reliable aluminum bonding to withstand stress, the mating surfaces are carefully cleaned, etched, rinsed and dried. An epoxy and hardener designed for metal-to-metal bonding is then used for a rigid assembly.
Reliability and quality control in manned spacecraft
Liquid rocket engine reliability evaluated, using static firing test data
Highly reliable earth sensor for determining orientation of space vehicle with respect to earth
Stainless-steel screen used to lay room temperature curing epoxy adhesive permits reliable bonding of electronic circuits boards. This technique would be useful with thin-walled structures that warp during conventional bonding operations.
Spring-loaded probe makes a reliable electrical contact by producing a circular wiping motion at the tip when inserted into a mating socket.
Monte Carlo method for developing design reliability goal compatible with small sample requirements
Reliability study of jet pipe, armature assembly, and torque motor for hydraulic servovalve development
Space environment effects on long-time stability and reliability of plastics for space vehicles
Integrated mission simulation technique tests pilot reliability for seven-day manned lunar mission
Simple, stable and reliable transistor DC FEEDBACK voltage amplifier employing differential input stage coupled with single common emitter stage for gain and drift rate dependence on temperature
Two-transistor multivibrator has minimum power dissipation and maximum reliability. It minimizes the use of components that are subject to environmental changes or other unpredictable behavior.
Intermediate rotating ring improves the reliability of dynamic shaft seals whose rubbing surfaces wear down rapidly at high shaft speeds. The rotating ring is placed between the rotating shaft sealing surfaces and the stationary surface, and driven at one-half the shaft speed.
Brazing process employs an aluminum-silicon filler alloy for diffusion bonding of aluminum parts in a vacuum or inert gas atmosphere. This process is carried out at temperatures substantially below those required in conventional process and produces bonds of greater strength and reliability.
Limit switch for reliable, low-travel, snap action with negligible arcing uses an electrically nonconductive permanent magnet consisting of a ferrimagnetic ceramic and ferromagnetic pole shoes which form a magnetic and electrically conductive circuit with a ferrous-metal armature.
