Title: Treatment for making raw material from chlorine-containing resin coated steel products and apparatus therefor
Inventor: ASANUMA MINORU
IPC: C22B1/00
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To make it possible to treat chlorine-contg. resin coated steel products at a low cost without the occurrence of the problem by the chlorine-component in the resins by using materials to be treated which contain the resin residues subjected to the removal of the chlorine-components by a heat treatment and steel products as furnace raw materials. SOLUTION: The chlorine-contg. resin coated steel products which are the materials to be treated or the materials to be treated which contain the chlorine-contg. resin coated steel products are crushed by a crushing device 1. The crushed materials to be treated are heat treated by a rotary kiln furnace 2, by which the chlorine-components included in the chlorine- contg. resin coatings are removed. The materials to be treated after the heat treatment are supplied to the crushing device where the resin residues in the materials to be treated are disintegrated. The materials to be treated after the treatment are sieved by a sieving device 4. The gaseous hydrogen chloride generated in the rotary kiln furnace 2 is recovered as gaseous hydrogen chloride by a chlorine recovering device 5. The treated materials which are treated by the sieving device 4 are used as the furnace raw materials.  The raw materials are thus made from the chlorine-contg. resin coated steel products as resources for recycling.

Filed: 1990-10-25
Abstract: PURPOSE:To enable partial combustion in a catalyst layer for combustion and reduce the amount of NOx by carrying out the self-circulation of combustion gas to be mixed with primary fuel and increasing a temperature of the resultant mixed gas to a level suitable for catalytic combustion. CONSTITUTION:Vapor phase combustion by secondary fuel is first carried out, the self-circulation of a combustion gas at a high temperature is performed to be mixed with air 15, and a temperature of the resultant mixed gas 17 is increased to a level required for catalytic combustion. Since a mixed gas flow passage 41 is provided with an air inlet port 12 at a portion thereof, to which air is fed, and which is formed into a throttled shape, a negative pressure is caused at this portion, and combustion exhaust gas 16 in a furnace flows thereinto from an opening of a furnace wall 32 through an exhaust gas circulation passage 11, thus the circulation of exhaust gas is achieved. When a load level at the furnace becomes higher and a temperature of the mixed gas 17 reaches a level (300 deg.C or above for a propane and 450 deg.C or above for a methane) suitable for catalytic combustion, a feed valve 28 for primary fuel is opened by a signal from a temperature setter 22, whereby the air and the combustion exhaust gas flow to a catalyst layer 9 for combustion as the mixed gas for primary fuel.

IPC: G11B5/588
Filed: 1993-11-17
Abstract: PURPOSE:To always excellently start a tape and to prevent irregularities in a slow reproduced image regardless of a stop position by controlling the control characteristic of a capstan motor or maximum impressed voltage thereon at the time of starting the tape based on stop position information obtained from a tracking signal at the time of stopping the tape. CONSTITUTION:A signal recorded on the tape 1 is reproduced by a head 5, and a tracking error signal is outputted from a differential amplifier 37. The tracking error signal at the time of stopping becomes stop position information of three stages in accordance with a level in a capstan starting circuit 42. The circuit 42 starts a capstan motor 9 at such capstan control voltage that impressed voltage at the time of starting is maximum voltage when the stop position information shows the front of a target stop position, it is 70% of the maximum voltage when the information shows the target stop position, and it is 40% of the maximum voltage when it shows the back of the target stop position. Thus, the tape is started in the same timing regardless of the stop position.

Title: Chlorine concentration control of feed water for nuclear power station
Inventor: AIZAWA MOTOHIRO
IPC: G21D3/08
Filed: 1988-11-15
Abstract: PURPOSE:To enable a prevention of streaming-in of a chlorine ion into a reactor core in case of an accident of sea water leakage by detecting the leakage of sea water into a condenser at an outlet of the condenser and controlling a valve installed at a by-pass system with the detection signal. CONSTITUTION:In case of a sea water (a coolant) leakage into a condenser 8, a conductivity meter 21 provided at an outlet of the condenser 8 detects the leaking, and receiving a detection signal, a regulating valve 22 for a by-pass flow rate installed at a by-pass piping 20 of a condensate purification facility is completely closed. By installing the regulating valve 22 at a periphery of a condensate filter 10, a stored amount of the condensate containing a chlorine ion can be minimized and therefore a demineralizing treatment can be easily conducted. An occurrence of a sea water leakage is judged by a fact whether the detection value is larger than 0.1mu/cm which is a conductivity controlling value, or not. In case that all the condensate passes through the filter 10 and a demineralizer 11 according to the aforementioned system configulation and an operating procedure, any chlorine ion do not enter a nuclear reactor 1 even if a sea water leakage might occur. Therefore, an integrity of constituted equipments can be maintained and a safe operation can be achieved.

Abstract: PURPOSE:To obtain light-weight artificial gravel suitable as aggregate, etc., at a low cost by mixing pumice particles having a proper particle size with a heat-resistant coating material powder having relatively low melting point such as glass and calcining the mixture to cover the pumice core with the molten coating material. CONSTITUTION:Particles of pumice sieved to a proper size are mixed with a proper amount of powder of a heat resistant coating material having relatively low melting temperature such as glass and the obtained mixture is calcined. The surface of the pumice particle 1 forming a core is coated with the molten coating material 3 by this process. The objective artificial gravel containing a number of voids 2 can be produced by cooling the coated product. Since the molten coating material 2 is impregnated into the surface layer of the pumice particle 1 at an early stage of the calcination treatment, the fragile pumice particle 1 can be reinforced. At the same time, the produced artificial gravel has light weight and is utilizable for the reduction of the weight of concrete because the air in the void of the particle 1 is sealed and the dissipation of the air is inhibited by the coating layer.
