Title: Dsl power feeder method
Inventor: HIRAOKA TOSHIHIDE
IPC: H04L12/70
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To allow a subscriber to obtain a stable phone service even when a commercial power supply failes in a subscriber's house. SOLUTION: The DSL power feeder method is a feeder method for a digital subscriber line(DSL) where a telephone service is served to subscribers by transmitting a voice packet between a station side line terminator 1 and a subscriber side network terminator 2 interconnected through a subscriber line 3 as a payload of high speed digital communication. The station side line terminator 1 supplies power to the subscriber line 3 when receiving a fault detection signal, the subscriber side network terminator 2 transmits the fault detection signal on the occurrence of failure in a commercial power supplied to each circuit and activates only circuits required for the telephone service with the power supplied through the subscriber line 3.

Inventor: FUJII YOSHINORI
IPC: G01C17/00
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To enable the correct verification of the functioning of a direction measuring device with simple operation by forming a key groove which fits with a key on a cylindrical main body which fits into an installation case from above and stretching a metal wire at the lower part of the key groove. SOLUTION: The cylindrical main body 10 of a direction measuring device is provided with a cylindrical body which can fit into an installation case from above, and on its peripheral surface a key groove 11 which can fit with a key protruded on an installation case is formed. When the main body 10 is lowered and the key fits into the key groove 11, a metal wire 15 stretched at the lower part of the key groove 11 is cut. Then, the direction of the main body 10 in a state that the key fits with the key groove 11 of the main body 10 is measured by a direction meter 14, and the direction of the main body 10, i.e., the direction of the key is transmitted to the ground level via a cable. After this, by recovering the main body 10 to the ground level and examining the cut of the metal wire 15, it is determined whether the key fitted with the key groove 11 or not.  When the metal wire is cut, it is determined that a measured result is correct.

Title: Dehydration method for sludge
Inventor: ITODA YUTAKA
IPC: C02F11/14
Filed: 1987-09-25
Abstract: PURPOSE:To make it possible to obtain hard flocs having a high strength, thereby to improve dehydrating efficiency, only by adding to a sludge a partly water- insoluble polymer obtained by the copolymerization of a water-soluble vinyl monomer and a crosslinking monomer, and then mixing the polymer and the sludge by stirring. CONSTITUTION:A water-soluble vinyl monomer and a crosslinking monomer are copolymerized, with the amount of the crosslinking monomer being 0.0005-0.01wt.% based on the whole amount of the water-soluble vinyl monomer, thereby obtaining a polymer partly insoluble in water. This polymer is added to a sludge and they are mixed by stirring. This stirring forms hard flocs having a high strength and containing therein a small proportion of water. As a result, not only the amount of water removed by initial filtration can be greatly increased, but also the dehydrating efficiency can be improved and the water content in a cake formed through the dehydration can be lowered. Further, since the polymeric flocculant is present inside the flocs, the releasability of the cake from the filter cloth of the dehydrator after the dehydration can be further improved.
