Abstract: Disclosed is a method for preparing an active Nitraria tangutorum fruit extract comprising a solvent extraction and purificaiton process and/or a supercritical extraction process. Further disclosed are a pharmaceutical composition, a food additive and a health-care preparation each comprising the active Nitraria tangutorum fruit extract obtained by the method for preparing them, and use of the extract in the manufacture for a medicament for the treatment and/or prevention of a condition.

Abstract: The present invention relates to a class of phenylpyrimidone compounds, the pharmaceutical composition, the preparation method and the use thereof. More specifically, the present invention relates to a type of phenylpyrimidone compounds of the following formula I, the pharmaceutically acceptable salts or solvates thereof and to the pharmaceutical composition as well as the preparation method of the compounds. The compounds of formula I according to the present invention can effectively inhibit type V phosphodiesterase (PDE5), and thus can be used for the treatment of various vascular disorders, such as male erectile dysfunction, pulmonary hypertension and the like.

Abstract: A reflector molding apparatus includes two pressure rollers with pressure surfaces of the rollers comprising convex teeth and concave teeth in mesh. The reflection film is put on the aluminum sheet as the unmolded material. The unmolded material goes to the pressure surfaces in mesh and is molded to be a reflector. The surface of the resulting reflector is corrugated shaped because of the pressure of the rollers. The shape of the reflector changes with the pressure surface of the rollers.

Abstract: A video apparatus has a digital encoder which receives a first analogue video signal with ancillary information in a given time window and generates on an output a digital stream based on the first analogue video signal. A digital decoder is connectable to this output to generate a second analogue video signal. A switch selects between the first analogue video signal and the second analogue video signal as an output depending on a control signal based on the occurrence of said time window.

Abstract: A video apparatus has a first connector for outputting first RGB signals, a second connector for receiving second RGB signals, and an On-Screen Display circuit generating third RGB signals. A RGB generator generates fourth RGB signals. A first RGB switch is connected to the second connector and to the On-Screen Display circuit for receiving respectively said second RGB signals and said third RGB signals. The first RGB switch outputs fifth RGB signals. A second RGB switch is connected to the first RGB switch and to the RGB generator for receiving respectively said fifth RGB signals and said fourth RGB signals. The second RGB switch outputs the first RGB signals. A process to control such a video apparatus is also proposed.

Abstract: A video apparatus has a video source with a luminance output carrying a first luminance signal and a chrominance output carrying a chrominance signal, an OSD circuit generating OSD signals and a fast-blanking signal, and a connector for delivering video signals. A converter outputs a second luminance signal based on the OSD signals and a first switch is controlled by the fast-blanking signal selectively connects the converter or the luminance output to the connector and a second is switch is controlled by the fast-blanking signal selectively connects the chrominance output or a circuit generating a constant chrominance signal to the connector.

Abstract: A video apparatus has a first connector (28) for outputting first RGB signals (R42, G42, B42), a second connector (38) for receiving second RGB signals (R2, G2, B2), and an On-Screen Display circuit (26) generating third RGB signals (ROSD, GOSD, BOSD). A RGB generator (46) generates fourth RGB signals (R46, G46, B46). A first RGB switch (40) is connected to the second connector (38) and to the On-Screen Display circuit (26) for receiving respectively said second RGB signals (R2, G2, B2) and said third RGB signals (ROSD, GOSD, BOSD). The first RGB switch (40) outputs fifth RGB signals (R40, G40, B40). A second RGB switch (42) is connected to the first RGB switch (40) and to the RGB generator (46) for receiving respectively said fifth RGB signals (R40, G40, B40) and said fourth RGB signals (R46, G46, B46). The second RGB switch (42) outputs the first RGB signals (R42, G42, B42). A process to control such a video apparatus is also proposed.
