Title: Extracting method for metallic gallium
Inventor: KADOKURA HIDEKIMI
IPC: C25C1/22
Filed: 1985-04-23
Abstract: PURPOSE:To obtain high purity Ga in high efficiency by using sulfides besides Al and Ca compounds in pretreating a solution mentioned below when extracting Ga by electrolysis from an alkaline solution of Ga containing heavy metal ions as impurities. CONSTITUTION:First, metallic Al is added to the alkaline solution of Ga containing the heavy metal ions as impurities, which is subjected to reductive reaction. Next, Ca compounds are added to remove the forming solid matter by separation and subsequently water-soluble sulfides are added to the resulting solution to remove the forming precipitate by separation. The resulting solution is subjected to electrolysis to extract metallic Ga. By use of the above method, the heavy metal ions such as copper, lead, V, etc., in the solution can be precipitated in the form of sulfide and particularly V concentration can be lowered to a remarkable extent owing to the addition of water-soluble sulfides. Accordingly, high purity Ga can be obtained without causing the loss of Ga content.

Title: Accident detector
Inventor: OONISHI YUUSAKU
IPC: H02H7/26
Filed: 1988-04-11
Abstract: PURPOSE:To surely detect an accident by locking the closure of a switching unit when a time in which an output signal from first means for collecting variation in an electric amount caused by the accident exists exceeds a preset time while an output signal from second means for detecting the opening/closing operation of the unit exists. CONSTITUTION:A short-circuit accident occurs at a load side, the output of an OR circuit becomes '1'. On the other hand, an accident detector of a reclosure detects an accident, and a sectionalizer thereby loses power to open its circuit. As a result, an auxiliary contact 12 is opened, a main circuit state detector 13 receives it to output a logic signal '1', and the output of an AND gate AND becomes '1'. Thus, an accident number counter 14 advances its count by one. When it becomes the set value of a locking operation accident number setter 15, a closure locking contact 16 is opened, and it is automatically disconnected at an accident point.
