Abstract: A measurement apparatus for measuring a substrate, on which a measurement object is formed, and a correction method of the same is shown. The correction method includes measuring a reference phase by measuring a phase of a substrate for measuring the reference phase by using an image-capture part, acquiring a tilted pose of a reference plane of the measured reference phase to an image plane of the image-capture part, and calculating a height that is required to correct the reference plane with regard to the image-capture part based on the tilted pose. Therefore, based on a tilted pose of a reference phase in order to correct a reference plane being a reference of measuring a height, a measurement credibility of the measurement object may be improved.

Abstract: A substrate inspection apparatus for inspecting a substrate, on which a measurement object is formed, is shown. The substrate inspection method includes measuring a substrate, on which a measurement object is formed, generating a plane equation of the substrate, and acquiring a region of the measurement object formed on the substrate. After, by considering a height of measurement object a region of the measurement object is converted into a substrate plane by plane equation,. Then, the measurement object is inspected based on a region of the measurement object converted into a substrate plane by plane equation and a region of the measurement object by reference data. Therefore, an offset value of a measurement object is acquired according to a tilted pose of the substrate, and a distortion of measurement data is compensated by using the offset value, to improve a measurement credibility of a measurement object.

Abstract: An apparatus for preventing neck injury for use in a vehicle seat, which is connected between a recliner base installed on a back frame and a plate base on which a seat cushion is provided, may include a front connection link that is hinged to a front part of the recliner base at an upper end thereof and to a front part of the plate base at a lower end thereof; and a rear connection link that is hinged to a rear part of the recliner base at an upper end thereof and to a rear part of the plate base at a lower end thereof, wherein the front connection link is pivoted at a greater angle than the rear connection link such that the back frame moves in a forward direction in the event of a vehicle rear-end collision.

Abstract: A poorly soluble drug containing microsphere with improved bioavailability, an oral formulation comprising the same, and a method of preparing the same are provided, wherein the poorly soluble drug containing microsphere is a solid dispersion wherein the poorly soluble drug is dispersed in the water-soluble polymer carrier in a noncrystalline form by spray drying, thus increasing bioavailability of the poorly soluble drug.

Abstract: A DLP optical system is provided. The DLP optical system includes a lamp unit, an optical engine unit, a DMD, a prism, a projection lens, and a light-blocking part. The lamp unit provides light, and the optical engine unit is optically connected with the lamp unit, has optical parts for converting light incident from the lamp unit into an image signal therein, and includes a primary lens for transmitting the image signal. The DMD reflects the image signal transmitted from the primary lens, and the prism is formed closely to the DMD to adjust a path of light. The projection lens projects an on-beam of light from the prism that contributes to forming of an image onto a screen. The light-blocking part is provided on an incident side of the projection lens to transmit only the on-beam and shields light of a flat state region located between an on-beam and an off-beam.

Abstract: A three-dimensional (3-D) shape measurement method using a Moire measurement principle and a Stereo vision measurement principle is provided.

Abstract: Disclosed herein is a 3D shape measurement method and apparatus using a stereo moiré technique. The 3D shape measurement method measures the 3D shape of an object to be measured using a digital pattern projector and first and second cameras. The method includes a first step of projecting a phase-shifted fringe pattern onto the object to be measured using the digital pattern projector, a second step of acquiring four fringe images using each of the first and second cameras, and then acquiring two pieces of phase information using a moiré technique, and a third step of acquiring a pair of corresponding points, which satisfy stereo phase conditions for making all 2? ambiguity constants as integers, using the two pieces of phase information and then measuring the 3D shape of the object using the corresponding points.

Abstract: Disclosed herein is a vacuum vessel, capable of maintaining the freshness of food contained in the vessel for a lengthy period of time by creating a vacuum in the vessel. The vacuum vessel includes a main body (10) having along an edge thereof an annular protrusion. A seat (15) is disposed in the main body to seat an exterior receptacle containing food therein. A cover (20) covers the main body, and includes a valve mount part and a packing groove defined between inner and outer rings at a position corresponding to the annular protrusion of the main body. A packing (25) is fitted into the packing groove, and has an insert groove to engage with the annular protrusion of the main body, and an extension part to enhance a seal. A check valve (30)(130)(230) is mounted to the valve mount part of the cover.

Abstract: Disclosed herein is an adsorbent for removing mercury, which comprises sulfided iron compounds containing oxygen. In the adsorbent, iron compounds containing oxygen are sulfided to accumulate sulfur therein, thereby removing gaseous mercury.
