The manifold body comprises inside chambers for the mixing of said reagent flows with corresponding re-circulated product flows and a coolant fluid expansion chamber within which said pressure reducing means of said first and second reagent flows are positioned at least partially drowned by said coolant. Method for the start-up and shut-down of the generator, and a method for detecting the flooding of a fuel cell and a method for detecting the presence of gas leakages in the generator are also disclosed.

An X-ray imaging system comprises an X-ray tube (6), a ceiling suspension (2) for the X-ray tube, a detector trolley (12) with an X-ray detector (10) mounted thereon, an active sensor matrix (24), an optical indication unit (20) and a control unit (26). The active sensor matrix (24) is fixedly mounted on the ceiling suspension (2), the optical indication unit (20) is fixedly mounted to the detector trolley (12) and is adapted for emitting an optical indication (22) onto the active sensor matrix (24). The control unit (26) is connected to the active sensor matrix (24) and is adapted for acquiring the position of the optical indication (22) on the active sensor matrix (24) and to create control signals for aligning the detector trolley position and the ceiling suspension position relative to each other such that the optical indication is present on a predetermined spot on the active sensor matrix. This eliminates the need of a mechanically fixed arm carrying a detector unit at a fixed spatial relationship to an X-ray arm as the detector and the X-ray tube are be linked by a position following process.

To provide a ceramic powder having low bulkiness and good dispersibility.

In the ceramic powder, the volume ratio of aggregated particles having a particle diameter larger than a reference particle diameter is 35 vol. % or more and the volume ratio when ultrasonic dispersion treatment for 10 minutes at an oscillation frequency of 19.5 kHz and an output power of 10 W is applied is 4 vol. % or less. The reference particle diameter is a particle diameter equivalent to a cumulative 0.1 vol. % diameter from the large diameter side when the ceramic powder is subjected to ultrasonic dispersion treatment for 3 minutes at an oscillation frequency of 19.5 kHz and an output power of 150 W.

A substrate integrated waveguide (SIW) for phase shifter for millimeter wave applications has a waveguide with a plurality of curved sections and which passes through the substrate from a wave entry port to a wave exit port. The plurality of curved sections forms a serpentine path of curves in a first direction followed by curves in a second direction which are opposite the first direction. Phase shifting elements are positioned in the waveguide in each of the curved sections. The phase shifting elements may take the form of PIN diodes or a pattern of liquid metal filled vias in the waveguide.

The invention discloses a method and a system for stitch-bonded wool flocculus.
