Abstract: PURPOSE:To prevent the occurrence of a part forgotten to be painted out in a closed graphic by painting out with a point belonging to an area, which is located in the outside of the closed graphic and in the inside of a quadrangle, as the start point of black painting out and painting out all the internal area of the quadrangle in an exclusive OR mode. CONSTITUTION:A quadrangle 2 with four points, namely, (Xmin-alpha, Ymin-alpha), (Xmin-alpha, Ymax+alpha), (Xmax+alpha, Ymax+alpha), and (Xmax+alpha, Ymin-alpha), as vertexs is plotted, and a point Q belonging to the internal part of the quadrangle 2, which is also the external area of a closed graphic 1, is given by an expression Q=(Xmin-alpha/2, Ymin+Ymax)/2). An area A is painted out in black with this point Q as the start point. Next, all the internal area of the quadrangle 2 is painted out in black in the exclusive OR mode. Thus, only all the internal area of the closed graphic 1 can be painted out in black.

Title: Formation of fine image
Inventor: OBATA HIROYUKI
IPC: G03G13/26
Filed: 1983-06-28
Abstract: PURPOSE:To improve the size stability of a fine image by forming the image of a material which contains coloring matter on the surface of a heat-shrinkable substrate, and then shrinking the substrate and image by heating. CONSTITUTION:The image 2 is formed on the heat-shrinkable substrate 1 and then the whole is heated to shrink the substrate 1 and image 2. The heating temperature of the shrink is higher than the softening temperature of the material of the substrate 1 and should not exceed the melting temperature. The heating time is 1-10sec. The substrate after being heated and shrinking is preferably cooled naturally or a forcible method such as air blowing. Thus, the image 2 is formed of the material containing the dispersed dye, and consequently the dispersed dye permeates the heat-shrinkable substrate 1 from the image 2 by diffusion, so even if the image 2 peels off during the shrinkage, the diffused permeation part 2A remains, preventing the defect of the image. This constitution allows low resolving power that the image formed initially requires, so the selection range of a means used for image formation is widened and economy based upon the improvement of yield is improved.

Title: Steam hole structure in electric rice-cooker
Inventor: MIYAMOTO HIROYUKI
IPC: A47J27/00
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To certainly separate sticky matter from steam, by tangentially provid ing and opening a sticky matter flow inlet inside of the inner peripheral wall of a sticky matter reservoir, forming the inner peripheral wall of the sticky matter reservoir except for the sticky matter flow inlet in a circular shape, and providing a steam hole in the central upper part of the sticky matter reser voir. SOLUTION: When a sticky matter containing steam is blown up to a cylindrical portion 14' following progress of rice-cooking, the sticky matter is turned in the tangential direction A by a bent surface 14a and flows into a sticky matter reservoir 11 through a sticky matter flow inlet 14. Then, turning flow occurs along the inner peripheral surface. A swollen out portion 20 is formed so that the flow moderately moves from the circular inner peripheral surface, and therefore, does not disturb turning of the sticky matter. Even if some flow-in speeds into the sticky matter reservoir 11 may be low and sufficient turning may not be performed, when a matter having high flow-in speed flows later, it adheres the previous matter due to adhesiveness of the sticky matter and turns together, and therefore separation between the sticky matter and steam is performed.

Abstract: PURPOSE:To enable to flatten a selectively epitaxial grown layer by a method wherein an etching method is used in which the etching speed is rather large when the incidence of an etching medium is inclined in relation to an etching surface. CONSTITUTION:An SiO2 film 2 is formed on the surface of an Si substrate 1.

Then high-frequency sputter etching is performed from the upper part of the layers 3a, 3b and the film 2. When high-frequency sputter etching is performed in such a way, the slanting surfaces are etched higher than the flat parts at first to remove the clusters 5 and the protrusions 4, etc. The etching speed at the horizontal is slow sgainst thereto. Accordingly, flattening of the selectively epitaxial growth layer can be attained.
