Title: Reflective photomask blank, and method for manufacturing reflective photomask
Inventor: SAKURAI KEISUKE
IPC: G03F1/24
Filed: 2023-05-03
Abstract: A reflective photomask blank includes a substrate, a multilayer reflection film that reflects exposure light being light in extreme ultraviolet range, a protection film, a light-absorbing film that absorbs the exposure light, and a hard mask film that is formed in contact with the light-absorbing film. The hard mask film is constituted by a multilayer including a first layer disposed at the side remotest from the substrate, and is composed of a material that is resistant to chlorine-based dry etching, and removable by fluorine-based dry etching, and a second layer composed of a material that is resistant to fluorine-based dry etching, and removable by chlorine-based dry etching. An etching clear time of the light-absorbing film on fluorine-based dry etching under one condition is longer than an etching clear time of the first layer on the fluorine-based dry etching under the same condition.

Title: A device for the separation of a liquid, especially whole blood.
Inventor: LARSSON LARS-AKE LENNART
IPC: A61K35/14
Filed: 1980-12-15
Abstract: Device for the centrifugal separation of a liquid, especially whole blood, into fractions having different densities. Said device comprises a rotatable separation unit (5) comprising a separation chamber (5'), and a transferring element (2) in fluid communication with said chamber The transferring of said liquid and said separated fractions between a source for said liquid and said separation chamber is realized without use of rotating couplings in that one end (3) of said transferring element is held fixedly, while the other end (4) thereof, i.e. the end which is next to said separation chamber, is rotatably connected to said chamber. As well said separation unit as said transferring element thereby will perform a rotation, when said separation chamber is rotating around an axis through said one end of said transferring element. Said transferring element (2) is thereby prevented from twisting or winding. More precisely, said transferring element (2) and said separation unit (5) will rotate one revolution (secondary rotation) per revolution made by the separation unit (5) when rotating (primary rotation) around said axis through said fixedly held end (3). By suitable choice of ratio between radius (r) of said separation chamber and radius (R) of said primary rotation, i.e. the distance between said separation chamber and the axis through said fixedly held end, said secondary rotation may be used to separate said liquid already before said liquid enters into said separation chamber (5').
