Another important consideration for the rotary joint is the fluctuations in the coupling of the light from the stationary fiber to the side-firing fiber as a function of the angular position of the tip.
The 2nd-stage targeting device consists of a transparent baseboard with three aligning lines, conductive rings, three magnetic pins with rotary joints, and an indicator, as shown in Figure 3(a).
In this two-antenna prototype, antenna A (the dedicated transmitter) was physically moved to 9 transmission positions while antenna B (the dedicated receiver) was moved to 11 receiving positions via the use of the rotary joint in conjunction with the modified antenna geometry.
The twosome removed the last six solar alpha rotary joint launch restraints and prepared the joint for rotation.
The rotating platform includes the microwave diplexer and rotary joint system.
The FO-5704 is a multipass fiber-optic rotary joint designed to allow optical signals to pass from a stationary structure to a rotating mechanism in a fiber-optic system.
The control system's transceivers convert incoming electrical signals to an optical format and condition the signal for transmission through the fiber-optic rotary joint (FORJ).
A rotary union (also referred to as a rotary joint) consists of a metallic rotating housing and a stationary shaft assembled together with seals and bearings.
Features of the SX rotary joint are said to include design for oil, water and steam; two internal support guides; optimized seal diameter; convex seal ring in compression; maximum carbon guide separation; and single-flow or dual-flow design.
Engel's version, available from 27.5 to 440 tons, puts the moving platen on a "self-adjusting rotary joint" that allows the mold face on the moving platen to re-orient itself relative to the one on the fixed platen as the two halves come together.
Advantages include - 113 dBm sensitivity over 1 to 18 GHz using fundamental mixing; - 100 dBm sensitivity to 26.5 GHz using the same module and third harmonic mixing, coverage can be extended to 110 GHz with the addition of mm-wave mixers; mixers placed at the antenna that can be separated up to 45 meters from the HP 8510B receiver/LO source for outdoor range configurations; and an LO/IF diplexer that is built into the test channel mixer to allow use of a single channel rotary joint in the test antenna's positioner, in lieu of flexible cables, for improved phase accuracy.
In the early 1900s, a breakthrough called the rotary joint enabled the industry to use closed pressurized systems and thereby regulate temperature precisely.
