IPC: E03B7/07
Filed: 1987-07-17
Abstract: PURPOSE:To enable early discovery of a water leak while permitting accurate detection of the position thereof, by running a leak detector within a sewer for draining spring water installed in order to prevent the floating of a water shielding layer. CONSTITUTION:In a facility where a solution containing a poisonous pollutant is generated, to prevent underground permeation of the poisonous pollutant, a water shielding layer 2 is formed on an entire surface of a slope at a final disposal plant. A wear 3 is provided on the downstream side of the slope in order to block the collapse of trash 6 and furthermore, to prevent the floating of the water shielding layer 2 caused by the spring water, a sewer 4 for draining spring water is buried below the water shielding layer 2 in sticks so as to cover almost the entire area of the water shielding layer 2. When the content of the pollutant is detected in the spring water to secure the certainty of damage to the water shielding layer 2, a water leak detector 1 runs toward the upstream side from the downstream side within the sewer 4 to perform an inspection of water quality in the sewer 4 and the position of a leak is detected based on a video of the condition of an inflow as obtained with a monitor camera.

Inventor: WATABE TAKASHI
IPC: G01S7/32
Filed: 1990-07-06
Abstract: PURPOSE:To give the same identification number to the echo of the same target by giving identification numbers to echo pattern data obtained by applying a 1st and a 2nd sliding window of necessary configuration to data on a quantized two-dimensional echo pattern. CONSTITUTION:A quantizer 3 quantizes the received data of a radar, etc., by azimuths and distances to generate the two-dimensional echo pattern. The processing of a 1st sliding window detector 4 configured including data which are equal in distance and different in azimuth is applied to the pattern data. Then the processing of a 2nd sliding window detector 5 configured including data which are different in azimuth and distance is applied and echo pattern data in the 2nd sliding window are given identification numbers according to set pattern data identification references by data patterns in the window. Consequently, even if the same target has plural divided echo patterns, those echo data can be given the same identification number.

IPC: B41M5/392
Filed: 1991-07-18
Abstract: PURPOSE:To visually identify the kind of contents without clear indication by wrapping heat-sensitive recording materials in the conditions suitable to their natures while maintaining the handling easiness. CONSTITUTION:Heat-sensitive recording materials 10 are wrapped in a double layer package consisting of a bag 16 and an inner bag 20. The inner bag 20 is formed of UV cut film which does not allow a light having a wavelength of at most 450nm to transmit therethrough and the lights having the wavelengths of 420nm and 365nm are not shone on Y dye layer and M dye layer to prevent the lowering of density upon recording. Since the recording materials are in a sealed condition and no air flow is produced therethrough, they are little affected by ambient temperature and humidity and the discoloration thereof due to heat is prevented. A visual checking and identification can be made of the heat-sensitive recording materials 10 through a hole 18 formed in the bag 16 and then through the inner bag 20. A drying agent 22 and a deoxidizing agent 24 are sealed in both the inner bag 20 and the heat-sensitive recording materials 10 to prevent the deterioration and chemical changes.
