Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain a power supply apparatus by which a power supply ripple contained in an output voltage is suppressed by a method wherein an error voltage which is fed back to a switching power supply is corrected by the power supply ripple.

Title: Copper crucible for melting high melting point active metal
Inventor: IRIE TAKEFUMI
IPC: F27B14/10
Filed: 1993-12-17
Abstract: PURPOSE:To prevent wear and erosion in a melting step by forming a Cr-coating on an inner surface in contact with molten active metal and ingot by an electrolytic plating method. CONSTITUTION:A Cr-coating layer is formed on an inner surface of a water- cooled copper crucible having a water cooling jacket at a periphery in contact with molten active metal, ingot, etc., at the time of using. The coating is formed by an electrolytic plating method, or preferably a hard Cr plating method. For example, a method having the steps of fully filling Sargent bath in which H2SO4 is added to CrO3 in a copper crucible, and dipping a lead anode in liquid with the crucible as a cathode to electrolytically plate it can be used. In this case, a hard Cr-plating layer having a micro Vickers hardness of a range of 500-1,200 is formed by controlling a liquid temperature and a current density. Accordingly, wear of an inner surface of the crucible due to contact with solidified high melting point active metal can be extremely effectively suppressed by its coating action.
