Title: Automatic section switch for distribution line
Inventor: KAJIMA TOSHIRO
IPC: G01R31/08
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To disconnect the faulty section of a grounded loop system distribution line automatically by making a decision that its own section is faulty when the absolute value of phase difference of overcurrent generating phase between its own section and an adjacent section on the load side exceeds a specified value thereby opening a section switch before the distribution line is recovered. SOLUTION: When a distribution line 13 is interrupted through a control processing section 34, serial interface 40 and a communication modem 42, overcurrent information and phase difference information is received from a memory 35 in the following section on the load side through communication with a switch controller 22 in that section when the overcurrent information is present in its own section and occurrence of overcurrent is detected, the control processing section 34 determines the absolute value of difference between a phase difference of overcurrent generating phase of its own section and a phase difference of overcurrent generating phase of the following section on the load side stored in the memory 35 and makes a decision that its own section is faulty when the absolute value exceeds 90 deg..  Consequently, a section switch 20 is opened before the distribution line is recharged and recovered along with a control output circuit 38 and an open coil 29.

Title: Treatment of waste pyrophosphoric acid copper plating solution
Inventor: MASUDA KOUSAKU
IPC: C02F1/62
Filed: 1984-01-30
Abstract: PURPOSE:To enable the re-utilization of copper by performing safe treatment fitted for regulation in low cost, by depositing a copper-containing crystalline substance by adding an acid to the titled waste solution and, after separating said crystalline substance, reducing copper leaked in the resulting solution by iron. CONSTITUTION:The pH adjustment of a waste pyrophosphoric acid copper plating solution is performed by the addition of hydrochloric acid or sulfuric acid to form a slurry in which a copper-containing crystalline substance is deposited. This slurry is subjected to solid-liquid separation to suppress a copper ion leaked in the separated solution to a definite range. The separated copper-containing crystalline substance is re-utilized or discarded. The copper ion leaked in the aforementioned separated solution is reduced by an iron powder to be deposited as metal copper which is, in turn, separated from the solution while the separated metal copper is re-utilized or discarded and the separated solution is discarded after neutralization.

Abstract: PURPOSE:To enable a picture to move smooth so that the encoding of a CODEC for a video telephone picture of good quality is realized by restricting a quantization step in accordance with a moving amount. CONSTITUTION:A transmission control circuit 203 sets beforehand the quantization step in a quantization step control circuit 202 in accordance with the moving amount, and sets an encoding parameter 212 in an encoding circuit 204. When the encoding is started, a moving amount detection circuit 201 reads out a picture signal 10 from a camera, and simultaneously, it reads out the picture signal 215 of the one preceding picture stored in a frame memory 200, and takes the difference of these two pictures by the moving amount detection circuit 201, and calculates the moving amount, and transfers it to the quantization step control circuit 202. Then, the quantization step control circuit 202 transfers the quantization step 214 corresponding to that moving amount to the encoding circuit 204. In this case, when the moving amount is small, the qunatization step is made small, and when the moving amount is large, the quantization step is made large.
