A method for creating a 3D map of the surface contours of an object includes projecting a variety of patterns onto the object, and imaging the patterns as they fall on the object to encode the topographic features of the object. In one embodiment a three dimensional image is taken in a single flash to avoid blurring due to motion of the object. Thereafter a secondary pattern is projected to detect changes in the initial image. The images are processed in a computer program in a manner such that a complete 3D map of the surface of the object is obtained in digital form. Reiteration of the method can detect motional variation such as a breathing human, flexure of a complex mechanical structure, or a stress-strain testing of an airplane, vehicle, beam, bridge, or other structure.

A writing implement (1) is provided with: a writing implement body which has a pen point (3) provided at the front end of a shaft cylinder (2); and an ink cartridge (6) which is connected to the rear end side of the writing implement body. The ink cartridge (6) includes: a closed-end circular cylindrical container (7) which has an open front end and a closed rear end; and a plug body (8) which is fitted to the inner peripheral surface of the opening (72) of the container (7). The writing implement body includes: a protrusion (53) which is inserted into the opening (72) and presses the plug body (8) rearward, thereby opening the ink cartridge (6); and an airtight connection section (52) which is formed separately from the protrusion (53) and which surrounds the protrusion (53). When the airtight connection section (52) and the opening (72) are airtightly fitted to each other, the opening (72) is divided into multiple sections. As a result, flow passages extending in the front-rear direction are formed in the outer periphery of the protrusion (53). At least one of the flow passages serves as an ink flow passage, and at least one of the remaining flow passages serves as an air introduction passage.

In a magnetic carrier, the surface of a magnetic body core material is coated with a coating layer containing conductive particles and a charge control agent composed of the same components as the charge control agent contained in the toner for electrophotograph. Furthermore, the electric resistance of the magnetic carrier under an electric field of 4 x 103 V / cm is from 8.22 x 107 to 1.12 x 1010 Ocm. The ability of charging the toner for electrophotograph can be sustained even after a long time.

The invention discloses a water-in-water multicolor paint preparation method capable of high-speed slicing and granulation. The preparation process comprises the following steps: preparing an 8% protective glue solution; 2. preparing a basic paint; 3. preparing a basic color paint; 4. preparing a multicolor particle solution; and 5. preparing the water-in-water multicolor paint finished product. After the color matching is carried out on the basic paint, the 8% protective glue solution is utilized to perform system reinforcement; and in the granulation and slicing process, the 8% protective glue solution and a hydrophobic modified anionic surfactant are premixed, so that the negative-valence ions in the anionic surfactant sufficiently capture cations on the nano modified magnesium lithium sodium silicate mineral salt molecule surface to form a series of strict film structures, thereby eliminating the risk of rejection caused by color bleeding, fusion and thickening since colored particles can not be completely coated in time. Thus, the obtained water-in-water multicolor paint has the advantages of excellent mechanical strength, excellent toughness and high spraying efficiency. The invention also discloses a composition of the water-in-water multicolor paint.
