| 20080237050 | ELECTROCASTING METHOD - The present invention provides an electrocasting method by which the shape of the surface opposite to the surface to be electrodeposited on the mold can be controlled. A molded metal article is electrocast by forming an insulating layer on the side wall faces of a cavity and the outer wall face of a conductive mold in which the cavity is formed, placing the mold in an electrolysis tank and applying voltage, electrodepositing metal on the bottom face of the cavity, and growing the metal layer in the cavity so as to leave a space having a height of at least one-third the width of the cavity. | 10-02-2008 |

| 20110233063 | ELECTROFORMING METHOD - A mold is fabricated with a cavity formed in an insulating layer formed so as to be placed on an upper surface of a conductive base material. This mold is disposed in an electrolyte bath to be applied with a voltage, and a metal is electrodeposited on the bottom surface of the cavity to electroform a metal-formed product in the cavity. In this electrodepositing process, when the width of the cavity is taken as W and a vertical height of a head space between an upper opening of the cavity and an upper surface of a metal layer is taken as H, the growth of the metal layer is stopped so that the height H of the head space left above the metal layer satisfies: H≧W/2.85 where 300 μm≦W; H≧W/3.75 where 200 μm≦W<300 μm; H≧W/4 where 100 μm≦W<200 μm; and H≧W/10 where W<100 μm. | 09-29-2011 |

| 20090209693 | Silver Beta-Ketocarboxylate, Material Comprising the Same for Forming Silver Metal, and Use Thereof - It is an object to provide a novel material that can quickly form metal silver even at a low temperature of approximately 210° C. or less. This serves as a metal silver forming material that includes a silver β-ketocarboxylate. By heating this forming material, it is possible to form metal silver quickly even at a low temperature of approximately 210° C. or less. Examples of the silver β-ketocarboxylate include silver isobutyrylacetate, silver benzoylacetate, silver acetoacetate, silver propionylacetate, silver α-methylacetoacetate, and silver α-ethylacetoacetate. | 08-20-2009 |
