Factory automation is what we say an industrial automation. Industrial automation means all types of automation done in industry. Industrial automation is the complete automation of the entire process done an industry where there is least human intervention in process, apart from that the only job a human does in monitoring and controlling the whole automation via SCADA or DCS.
Process automation is a kind of Factory automation because process industry is a kind of industry. Process industry is the one related with refineries, paper and pulp, petrochemical, etc. Because they have tendentiously more PID control processes than any other industry. This is why it’s called process automation.
There are conceptual differences between factory automation and process automation.

If you want to connect a 3-phase motor to a single phase power supply, then you have several solutions:
1) use a VFD with a single phase input and convert to 3-phase output, this is generally available for low power VFD (few horsepower).
2) apply a specially wound transformer that also mimic a 3-phase system from a single phase power supply. Expect difficulties to source and high price.
3) calculate a capacitor that will be connected between the remaining phases, such to apply it a phase shift and to mimic a 3-phase system.

It's successful that use laser welding machine on the implanted pacemaker for seam welding. This passage describes the laser welding machine structure and selection of welding technology parameters. With the development of medical technology, in recent years, the demand for implanted heart pacemakers is growing. In order to develop this product, ATO actively cooperates with relevant enterprises to apply laser machining technology to the heart pacemaker industry. After more than one year repeated experiments, finally solved the implant type pacemaker shell sealing welding technology, meet the extremely strict quality requirements of the cardiac pacemakers' production.

Laser marking allows you to create a high-quality, high-value signs and marks that make your metal signs and marks greatly different from your competition. Laser marking respond quickly to customized and one-of-a-kind applications that are difficult and expensive to produce using alternate methods and materials. The laser is like a pencil-the beam emitted from it allows the controller to trace patterns onto the surface. The controller (usually a computer) controls the direction, intensity, speed of movement, and spread of the laser beam aimed at the surface. The surface is picked to match what the laser can act on.
