Title: Process for removing impurity in liquid
Inventor: SASAKI YOSHINORI
IPC: C02F1/469
Filed: 1983-03-02
Abstract: PURPOSE:Impurities, such as Ca, contained in the liquid taken out of an anode chamber by a simple procedure by taking out the liquid for removing impurites in an anode chamber of a diaphragm type electrolytic cell after sticking impurities in the liquid to be treated to a cathode by carrying out electrolysis in a diaphragm type electrolytic cell. CONSTITUTION:The inside of a diaphragm type electrolytic cell 1 is partitioned by a diaphragm 4, and one of the partitioned chamber is used as an anode chamber by inserting an anode 2 thereinto, and another chamber is used as cathode chamber by inserting a cathode thereinto. Water 6 contg. impurites is poured into the electrolytic cell 1 and electrolysis is performed using DC supplied from an electric power source 5. If Ca is contained as impurity in the water, migration of the ion is caused in the cell 1; O2 is generated at the anode 2 to increase hydrogen ion concentration, and H2 is generted at the cathode to decrease the hydrogen ion concentration, and Ca ions are converted to Ca(OH)2 and adhere to the cathode 3. The Ca(OH)2 is discarded, and the water in the anode free from the impurity is taken out and used as purified water.

Title: Smelting method of copper
Inventor: OTO SHUICHI
IPC: C22B15/00
Filed: 1985-02-25
Abstract: PURPOSE:To decrease magnetite contained in slag, to make the copper loss contained in slag an extremely low value and to attain the increase of the collection degree of copper by covering the surface of molten copper in a smelting furnace with a solid reducing agent and adding a small quantity of reducing agent so that only the reducing agent consumed by the combustion is replenished. CONSTITUTION:The oxidizing reaction is caused in a reaction shaft 1 by introducing a copper ore 2 into the shaft 1 and sending an O2 source 3 therein to obtain slag 5 and a matte 6 in a setter 4. Slag 5 is drawn out through a slag hole 7 while preventing the involution of O2 from a low part of the slag layer. A small quantity of heavy oil as a reducing agent is introduced into a smelting furnace 13 wherein a top layer is covered with coke 11 through a reducing agent introducing port 8 provided to one part of a slag charging gutter 9 while reducing remarkably Fe3O4 contained in the slag. In this period, the slag 5 is discharged through a slag hole 12 after the settling of the slag 5 and the matte 6 is sufficiently finished. As a result, the copper loss contained in the slag can be regulated to an extremely low value e.g. 3% because Fe3O4 contained in the slag can be held in an extremely low value without oxidizing it.

Title: Granule of rare-earth metal oxide
Inventor: KIMURA YUJI
IPC: B22C3/00
Filed: 1990-02-16
Abstract: PURPOSE:To suppress the formation of a reaction hardened layer by using a granule composed of particles classified into three kinds of particle diameter ranges at specific ratios. CONSTITUTION:A wax mold having the objective form is dipped into a slurry of ceramic powder to coat the surface of the wax with the slurry.

Title: Paper feeding device
Inventor: MATSUMOTO MASASHI
IPC: B41J13/00
Filed: 1994-03-07
Abstract: PURPOSE:To feed a medium, of which the thickness of the right and left sides is different from each other, without necessitating the adjustment of the balance of the right and left pressing force of pick rollers and without causing skew and faulty feeding. CONSTITUTION:A plurality of pick rollers 3 receives driving force from a pick motor 5 through a rotary shaft 6 and a gear 6b. The pick rollers 3 are held by pick covers 3a energized downward by springs or the like respectively, and each pick cover 3a is turned around the rotary shaft 6. When feeding paper sheets to a printer 4 or the like, a hopper motor 1b is driven to lift a hopper 1 to set it at the paper sheet reference position. In the next step, the pick roller 3 pick paper sheets 2 by rotating the pick motor 5, and paper sheets 2 are separated from each other by a separation pad 7 and are fed to the printer 4 or the like one by one. Since a plurality of pick rollers 3 move independently of each other, even if the thickness of a paper sheet is uneven, it can be fed without causing skew and faulty feeding.

CONSTITUTION:When valve stems 21, 21' and 22, 22' move upward from the state of ''closed'' wedge receptacles 18a, 18b come off from the wedge members 19a, 19b of the valve chest 1 to allow the valve closing elements 11a, 11b to slide into the upper box 2 and, at the same time, the valve opening elements 12a, 12b slides off from the lower box 3 into the valve chest 1, whereby the tapered faces of the valve elements 12a, 12b come in contact with the tapered face of the intermediate seat 7 when the elements 12a, 12b attain a position where the opening of their flow lines 13a, 13b are in correspondence with the openings of the flow lines 6a, 6b, 9. Thus the valve openings 10a, 10b are sealed. When valve stems 21, 21' and 22, 22' move downward thereafter, the valve elements 12a, 12b slide into the lower box 3 and the valve elements 11a, 11b into the valve chest 1 to be fitted between the valve seat 4a, formed at the valve chest, and the valve seat 7 and between the valve seat 4b, formed at the valve chest 4b, and the valve seats 14a, 14b make a close contact with the valve seats 4a, 4b. Thus the pipes A and B are separated.

IPC: F27B14/08
Filed: 1988-02-18
Abstract: PURPOSE:To make longer the life of a crucible, save energy and make it possible to raise the quality of molten metal by installing freely rotatably a rapid melting furnace to a support column that is erected at the side of the main body of a pot furnace and opening in the furnace main body a smoke stack which goes to the melting furnace via the support column. CONSTITUTION:A rapid melting furnace 5 is installed to a support column 3 freely rotatably above a crucible 1 so as to be able to get near or go away from the crucible 1. The flame of a main burner 9 goes round the crucible 1 and after the flame heated the molten metal 4, it goes through a smoke stack 6 and get into a rapid melting furnace 5 to melt a cold charge 16 together with an auxiliary burner 16. The melted cold charge 16 flows down to the crucible 1 from a molten metal reservoir 15 through a supply trough 7. With this arrangement the temperature of the molten metal does not drop temporarily when a cold charge is charged, and a continuous operation can be made without any trouble. Additionally the heat of the high temperature exhaust gas which comes from a port furnace 2 can be used to preheat and melt the cold charge 16 with a contribution to energy saving.

Filed: 1985-02-25
Abstract: PURPOSE:To form a fluorescent film free from any mixed color and any reduction of the luminance by mixing phosphor particles with pulverized aluminum oxide in a given ratio by weight relative to the mean particle diameter of the phosphor particles prior to using them. CONSTITUTION:After a given pattern area 7a of a photosensitive adhesive layer 7 on a base plate 6 is exposed to light to make the area 7a tacky, a powdery mixture 13 prepared by adding a given amount of pulverized aluminum oxide 12 to green-color-emitting phosphor particles 8G is sprinkled over the exposed area 7a to make them adhere to the exposed area 7a and then a surplus mixture is removed by blowing air or a similar method thereby forming a desired fluorescent film 9G. In the same manner as above, a blue-color-emitting fluorescent film 9B, a red-color-emitting fluorescent film 9R and a light- absorbing film 11 are formed. Pulverized aluminum oxide 12 is added to phosphor particles 8G and 8R before they are sprinkled over the exposed area 7a. due to the presence of pulverized aluminum oxide 12, the tackiness of the fluorescent film 9G, 9B and 9R is greatly reduced. Therefore, the possibility of phosphor particles and graphite particles 10 to adhere to these films during the subsequent process is greatly reduced.
