Thus such a board functions both as a chalkboard and as a flannelboard. We can display visual learning material on such a board while writing key points on it. Such a board provides the flexibility of movement of visual material. It is possible to display even a three dimensional object on such a board using magnetic holders. 

Liquid hydrogen stations could be run by robots. There already is such a station in Munich. Making liquid hydrogen work requires some new techniques, like attaching the tank to the car with a magnetic holder to isolate it from thermal convection.

The necessary mounting points in a rotomolded plastic product can be tightly fixed inside the mold as threaded inserts. Around the inserts, the plastic melts and forms a constant bonding. Threaded inserts can be held inside the mold with a screw, which has to be screwed in and out for each cycle. In industry, snap inserts (fixed inserts using spring loaded balls) or magnetic holders have established themselves. 

A mechanics-free airborne sound location system is used in order to record the probe movement and the rotation direction of the probe relative to the weld. Two airborne sound transmitters are arranged on the probe holder and two receivers are fixed on a 50 cm long rail equipped with two magnetic pads The exact probe position and rotation direction is continuously determined by system. 

A sample holder, including optics for focusing the incident light and collecting the luminescence. Efficient light collection is important, and the sample holder may need to allow for a cryostat, pressure cell, magnet, or electrical contacts. 

The deposition chamber is a cylindrical vessel with a diameter of 50 cm and a length of 80 cm. At about 5 cm from the arc outlet, silane can be introduced via an injection ring (7.5-cm diameter) that contains eight holes of 1-mm diameter each. The distance between arc outlet and substrate is 38 cm. The substrates are heated via the substrate holder, of which the temperature can be controlled between 100 and 500°C. Samples can be loaded via a load lock equipped with a magnetic transfer arm. The substrate can be optionally RF-biased. A residual gas analyzer...

The basic components of the traditional NMR instrument therefore include a large-capacity superconducting magnet, a sample holder, an RF transmitter, an RF receiver/detector, a sweep generator with... 

Seven components magnet, sample holder, RF generator, RF detector, sweep generator, sweep coils, and data system. See Section 10.4.2 for the function of each.
