Title: Measurement of corrosion
Inventor: YANAGISAWA MIYUKI
IPC: G01N27/26
Filed: 1981-04-28
Abstract: PURPOSE:To enable quick and continuous measurement of the corrosion rate of metal plates by measuring a decreased rate of the level of an electric charge which is applied in a fixed amount between the metal plates facing each other with a very small clearance. CONSTITUTION:With a switch S6 opened and a switch S8 closed, a fixed amount of an electric charge is applied to a capacitor 5 and then the switch 8 is opened and the switch S6 is closed. When the capacity of the capacitor 5 is set at a value by far small than that of a capacitor formed by the metal plates 1 and 2, the electric charge accumulated in the capacitor 5 shifts between the metal plates 1 and 2 momentarily. When the switchs 6 is opened, the potential between the metal plates 1 and 2 rises instantaneouly at a time t0 by applying a fixed amount of the electric charge between the plates 1 and 2 and then, gradually decreases with the passage of time. The corrasion rate of the metal plates 1 and 2 in the air can be determined by measuring the secular change of the potential.

Title: Line switching control device
Inventor: SAFUKU KAZUHIKO
IPC: H04L69/40
Filed: 1989-03-17
Abstract: PURPOSE:To accurately discriminate the cause of a fault in a current line and to switch the failed line by converting a transmission level into a required receiving level range as a reference value, switching to a unipolar stage having no hit only when the transmission level is less than the receiving level range, and when the transmission level is included in the range, executing only bipolar stage switching. CONSTITUTION:A transmission level is informed from the transmission side to a line switching control device 14 on the receiving side, A level range to be originally received is detected from the transmission level by a level comparing part 1 through a normal line and the detected level range is compared with a practical receiving level from a current line. When the transmission level is included in the receiving level range, only the bipolar stage switching can be executed. When the transmission level is less than the receiving level range, an alarm processing part 2 generates switching information for unipolar stage switching independently of the contents of alarm information at the time of receiving the alarm information and applies the switching information to a switching logical part 3. Consequently, whether the fault in the current line is due to an apparatus failure or a line failure such as fading can be accurately discriminated and the failed line can be switched.
