Title: Manufacture of medium-or low-carbon ferromanganese
Inventor: YAMAMOTO KOTARO
IPC: C22C33/04
Filed: 1986-03-31
Abstract: PURPOSE:To obtain economically medium- or low-carbon ferromanganese, by subjecting molten high-carbon ferromanganese to blow smelting by means of top-blown O2 gas and bottom-blown inert gas in the prescribed ratio and then to decarburization by means of bottom blowing of O2 gas and inert gas with specifying the ratio between the above gases and the temp. of molten metal. CONSTITUTION:The molten high-carbon ferromanganese usually of about 1,300-1,400 deg.C is subjected to top blowing and bottom blowing in the ratio of bottom-blown inert gas to top-blown O2 gas of 15-50pts.vol. to 100pts.vol. Then, at the point of time when decarburization proceeds to the extent that C concentration of ferromanganese comes to about 2%, top blowing of O2 is stopped and gentle decarburization by means of bottom blowing of O2 and inert gas, that is, decarburization in which the proportion of inert gas based on 100pts.wt. of O2 gas is regulated to >=20pts.wt. and the temp. of molten metal is controlled to 1,650-1,800 deg.C, is exerted. After that, decarburization is carried out until desired C quantity is reached, with reducing the ratio of bottom- blown O2 gas to bottom-blown inert gas as decarburization proceeds. As a result, the progress of decarburization is effectively controlled, so that medium- or low-carbon ferromanganese can be obtained more economically than by conventional silicide process or other oxygen-decarburizing processes.

Abstract: PURPOSE: To obtain a highly durable and reliable refrigerator in which liquid compression does not occur, by a method wherein two or more accumulators are provided and the open end of an inlet pipe of the accumulator on the downstream side of a refrigerant flow path is located at a higher elevation than the open end of an outlet pipe of the accumulator on the upstream side of the refrigerant flow path. CONSTITUTION: An accumulator 7 on the upstream side of a refrigerant flow path and an accumulator 8 on the downstream side of the refrigerant flow path are provided to completely gasify liquid refrigerant that remains un-evaporated at an evaporator 4, and connected by a piping. An open end 10 of the inlet pipe of the accumulator 8 on the downstream side of the refrigerant path is located at a higher elevation than an open end 9 of the outlet pipe of an accumulator 7 on the upstream side of the refrigerant flow path. Therefore, the liquid refrigerant is restrained from flowing into a piping between the accumulator 8 and a compressor 1 during defrosting operation and returns to the compressor 1 after it turns to gas refrigerant completely by the abrupt expansion in the accumulator 8 at the start-up time of the compressor 1.  As a result, troubles of compressing parts such as a cylinder due to liquid compression can be prevented.

Title: Cathode-ray tube device
Inventor: NATSUHARA MASAO
IPC: H01J29/50
Filed: 1982-05-06
Abstract: PURPOSE:To enable good resolutions to be realized over the entire area of a phosphor screen by correcting the configurational distortion of a beam spot caused by an electron beam which is deflected in an uneven deflecting magnetic field. CONSTITUTION:When an electron beam is deflected, an electron beam 24 is focused by focusing lenses 23', 23'' and 23''' more intensely in the horizontal direction than in the vertical direction, so that the electron beam focused weakly in the horizontal direction and intensely in the vertical direction in a deflecting magnetic field according to the increase in the degree of beam deflection is suppressed. As a result, even a beam spot formed by a horizontally intensely deflected electron beam can be caused to have a shape close to a true circle, and the resolutions of the both sides especially as well as the areas on the diagonals of a phosphor screen are increased. Consequently, since the distortions of beam spots appearing near the upper and the lower centers of the phosphor screen are originally insignificant, a very clear playback picture can be realized over the entire area of the phosphor screen.

The washing water is then injected into a heat exchanger 1 through an injection nozzle 5 to wash the heat exchanger. The washing water then enters into a drain pit 4. Stripped ammonia gas is sucked by a blower 6 so that the gas is supplied to ammonia-using facilities 7. The pH level of the drained washing water in the drain pit 4 is measured and adjusted to a prescribed value by a pH level adjuster 8 so that the washing water is circulated and used again. After the washing is finished, the washing water in the drain pit 4 is conducted as the supplement water to the desulfurization facilities 7a. The drained washing water is thus completely recovered and diverted to some other purpose.
