A shock absorber has a pressure tube with a piston assembly slidably disposed within the pressure tube and attached to a piston rod. The piston assembly divides the pressure tube into an upper working chamber and a lower working chamber. The piston assembly includes a frequency dependent valve assembly attached to the piston rod which defines a housing attached to the piston rod and a spool valve assembly. The spool valve assembly includes a spool valve and a bypass valve assembly that controls fluid flow through bypass passage that bypasses the piston assembly.

The solar photovoltaic photoconverter unit (1) comprises a light processing opto-photonic platform (2) realized by at least one transparent substrate (8) is having on, at least one, of its faces a digital diffractive grating constituted by slanted ribs (11) that are modulated to harvest a maximum of solar light at any angle of incidence to split it into several spectral sub-bands, to guide and to concentrate individually every one of these spectral sub-band, toward a separate output of the opto-photonic platform (2) for allowing its exploitation by a light-to-electricity conversion unit (3) that will have by optimization a grate overall conversion efficiency. The opto-photonic platform (2) also includes photonic converters (13) and (14) converting ultraviolet light into visible light and also infrared light in visible light for a better exploitation of the energy present in the solar light and so increasing the light to electricity conversion. The solar photovoltaic photoconverter unit (1) comprises also a light-to-electricity converter unit (3).

Die Erfindung betrifft insbesondere ein Ventilatorrad eines Axialventilators, das mehrere Schaufeln mit jeweils druckseitigen, sich radial auswärts erstreckenden Schaufelvorderkanten und radialen Außenkanten aufweist, wobei ein Übergang von den radialen Außenkanten zu den Schaufelvorderkanten jeweils mit einem sich in Umfangsrichtung erstreckenden Vorsprung gegenüber den angrenzenden, sich radial auswärts erstreckenden Schaufelvorderkanten gebildet ist, wobei ein Übergang von dem radialen Außenrandabschnitt (7) zu einem radial weiter innen liegenden Bereich der jeweiligen Schaufel fließend ausgebildet ist.
摘要:
Architecture of the light-to-electricity converter characterized in that the system of amorphized nanograins, preferentially nanograins of amorphized silicon, of any shape are optimally spread within the crystalline host material, preferentially crystalline silicon that are wrapped around with a metamaterial seg-matter nanolayer, characterized by secondary generation centers, called segtons, that are conditioned around divacancies and disposed entirely or only partly within the volume of the emitter, this volume being limited at each end by a nanomembrane assuming the appropriate exploitation of the lower-energy secondary generation through the giant photoconversion involving hot electrons, segtons, and seg-matter.
摘要:
A slat for use in a roll-out sheet of construction material is provided. The slat has an elongated body extending longitudinally. A projection is disposed at a first lateral end of the body. A socket is disposed at a second lateral end of the body, opposite to the first lateral end. The projection and the socket are structurally complementary to each other. A wedge is formed with the projection as a self-tightening mechanism. A roll-out structure is also provided. The roll-out structure has at least two adjacent slats which are structurally the same. The projection of one of the slats is insertable into the socket of the other slat to connect them, and the projection is rotatable in the socket. The rotation of the projection in the socket allows the wedge to engage the socket, to lock the slats with each other.
