  • Patent number: 11110061
    Abstract: The present invention relates to a biodegradable polymer microsphere-containing sustained-release injection containing escitalopram as an active ingredient, and to a method for manufacturing the same. In the case of escitalopram microspheres, there is a problem of low encapsulation rate, fracture due to weak strength, and initial over-release due to the phase separation of the liquid drug and the polymer inside the microspheres. In order to solve the problem, it is possible to maximize the encapsulation amount and the encapsulation efficiency of the escitalopram adding a hydrophobic solidifying agent to uniformize the non-uniform phase, to overcome the cracking of the microspheres at high loading conditions, and to properly control the initial release and release delay of the microspheres.

  • Patent number: 10591337
    Abstract: A lockable metering aerosol dispenser is disclosed for dispensing an aerosol product from an aerosol container through an aerosol valve. The lockable metering aerosol dispenser comprises a base secured to the aerosol container with a cup rotationally mounted to the base between a locked rotational position and an unlocked rotational position. A metering cup is secured relative to the base and communicates with the aerosol valve. The cup is capable of actuating the aerosol valve for dispensing the aerosol product into the metering cup when the cup is rotated into the unlocked rotational position. The cup is inhibited from actuating the aerosol valve when the cup is rotated into the locked rotational position.

  • Publication number: 20050140676
    Abstract: A three-dimensional map is displayed on a screen, and text data with different levels of density are displayed according to distances from a view point of the displayed three-dimensional map to nodes where the text data will be displayed, thereby improving readability of the text data. Further, it is possible to display the text data by locally adjusting the density of the text data on the screen. The three-dimensional map is displayed on the screen of a display panel by converting map data with two-dimensional coordinates into those with three-dimensional coordinates by means of a perspective projection method. Text data to be displayed together with the three-dimensional map are converted into those in a three-dimensional coordinate system with an origin defined by the view point of the three-dimensional map. The converted text data are projected on a two-dimensional plane to be converted into those with screen coordinates.
