Title: Short-circuit position detector
Inventor: SEKIYA SATOSHI
IPC: H05K3/00
Filed: 1986-07-25
Abstract: PURPOSE:To accurately detect a short-circuit position in a short time by supplying a constant current from one terminal of a conductor which is short-circuited to the short-circuit position and from one terminal of the conductor to the other terminal including the short-circuit position and measuring the ratio of generated potential differences. CONSTITUTION:When contact points Sa and Sc of a switch S are closed firstly, the constant current flows from a point N1 on the conductor P1 to the short-circuit position 5. The potential difference between points N1 and N2 on the conductor P1 is proportional to the length of the conductor from the point N1 on the conductor P1 to the short circuit position N5. A microcomputer A4 stores this potential difference. Then, contact points Sb and Sc of the switch S are closed and then the constant current flows from the point N1 to the point N2 on the conductor P1 to generate a potential difference proportional to the length of the conductor P1 from the point N1 to the point N2 on the conductor P1. The microcomputer A4 reads this potential difference and computes and displays the ratio to the stored potential difference on a display device A5. The ratio of the conductor length from the point N1 on the conductor P1 to the short-circuit position and the conductor length from the points N1 to the short-circuit position N2 is measured to detect the short-circuit position.

CONSTITUTION:While a waste organic solvent being supplied in vapor state to a sealed container 21 in heated atmosphere from a supplying pipe 51 by a nozzle 61, vapor of a heat medium (e.g. steam) having a boiling point higher than that of an organic solvent (e. g. acetone) in the waste organic solvent or than the azeotropic point of them is supplied from a supplying pipe 52 by a nozzle 61 and both are brought into contact with each other. The vapor of the organic solvent in the waste organic solvent which is evaporated at once by the heat exchange is introduced into a condensing apparatus 4 through a gas discharging outlet 11 and a valve 31 and there the vapor is condensed. The supplied steam is condensed and converted into dewdrops instantly by the heat exchange and drops fall due to self-weight. As a result, recovery ratio of the organic solvent becomes high and throublesome cleaning work for reuse of the container 21 becomes unnecessary.
