Title: Submerged nozzle for continuous casting apparatus
Inventor: OTSUGA DENJIRO
IPC: B22D41/50
Filed: 1986-05-16
Abstract: PURPOSE:To promote cooling and solidification of the center part of molten steel as stirring the molten steel, to restrain the center segregation of a cast slab and to obtain the good surface quality by pouring the molten steel as rotating a nozzle having two discharging holes, which pours the molten steel at different height into a cooling mold. CONSTITUTION:Revolution of electric motor 25 is transmitted to a drum plate 16 and the submerged nozzle 14 through a power transmitting shaft 26,... sprocket 20, and the submerged nozzle 14 is rotated at the prescribed number of revolution. As each discharging hole 14e, 14f of the nozzle 14 has difference of height, the swirling flow of the molten steel is widened toward upper and lower direction by this height difference to widen the stirring range. Therefore, heat conduction to the wall face of the cooling mold 13 cooled from liquids phase part 40b by cooling water is promoted and so formation of solids phase is quickened. Further, by centrifugal force effect caused by rotation of the molten steel, the surface layer inclusion of the cast slab 40 is reduced.

Title: Heat pump type air conditioner
Inventor: KIMATA MITSURU
IPC: F25B27/00
Filed: 1988-05-06
Abstract: PURPOSE:To prevent a bad influence on a refrigerant compressor caused by an extreme lack of refrigerant by a method wherein a vehicle air conditioner is provided with a water-refrigerant heat exchanger in which the refrigerant of which pressure is reduced and of which volume is expanded is heat exchanged with an engine cooling water during a heating operation to evaporate. CONSTITUTION:During a heating operation, refrigerant of high temperature and high pressure gas to be discharged from a refrigerant compressor 5 passes through a four- way valve 6, enters vehicle heat exchangers 8 and 9 to heat a compartment air and then the refrigerant is liquefied. A pressure of the refrigerant is reduced by an expansion valve 31, the refrigerant is expanded to become atomized refrigerant, enters a water-cooled heat exchanger 11, is evaporated with cooling water from an engine 2 and returned to the compressor 5. Accordingly, a refrigerant pressure is increased as a temperature of engine cooling water is increased so long as the refrigerant in a freezing cycle 4 is not extremely short due to a gas leakage and the like. Several repetitions of an operation of an electromagnetic clutch 3 cause a set value of a first pressure switch 38 to be exceeded and a compressor 5 may keep its driving state. In turn, if the refrigerant is extremely short, it does not exceed a set pressure of 0.2kg/cm<2> of a second pressure switch 39, an electromagnetic clutch 3 is turned off and a driving operation is terminated.

Title: Centrifugal casting method adding one directional magnetic field
Inventor: HASHIMOTO TAKASHI
IPC: B22D13/00
Filed: 1980-08-12
Abstract: PURPOSE: To reduce macrosegregation and imrpve casting structure by adding a unidirectional magnetic field to the molten metal under rotation, and allowing the molten in a solidification transistion layer to solidify while agitating the same.  
     CONSTITUTION: A pair of a unidirectional magnetic field generator 7 is provided by sandwiching the metal mold 5 and rotating rollers 6 of a centrifugal casting machine, and when a unidirectional magnetic field B is applied to the molten metal under rotation, the electromagnetic force accelerating the rotation in a tangential direction acts on one sides 3, 4 of the molten metal and the electromagnetic force conversely suppressing the rotation acts on the other sides 1, 2. The electromagnetic force toward the inner side in a radial direction acts on the one sides 2, 3 and that toward the outer side in the radial direction on the other sides 1, 4. Namely, this results in that the mutually opposite forces act upon the molten metal rotating in the magnetic field B, in the tangential direction and the radial direction according to the rotations, and this creates flow in the unsolidified molten metal in the solidification transition layer and accelerates effective agitation effect.

Abstract: PURPOSE:To obtain a stable in active layer, by implanting ions on the outside of a diffused layer region on the main surface side of a semiconductor substrate, so as to obtain amorphous material, thereafter forming a semi-insulating layer by implanting oxygen or nitrogen ions, and thereby making the concentration of the oxygen or nitrogen included in the amorphous layer uniform. CONSTITUTION:An opening part is formed on the outside of a P-type semiconductor region 12 and on the main surface side of a semiconductor substrate 11 by a photolithography process. A part of the semiconductor substrate 11 is exposed. Thereafter, e.g., Ar or Si ions are implanted at a high concentration, and an amorphous layer is formed. Thereafter, oxygen or nitrogen ions are implanted in the opening part, and the amorphous layer of a semi-insulating layer 13 is arranged. At this time, in addition to lattice defects caused by the ion implantation in the semiconductor substrate 11, an amorphous region is yielded. The amorphous region is recovered to a single crystal structure by annealing but is not recovered completely. Thus considerable amorphous region remains. Therefore, oxygen ions are implanted in the amorphous region, which is formed by the ion implantation. The post-treatment is performed at 500 deg.C or less, and a semi-insulating layer 13 is formed. Thus the semiconductor device having an inactive layer is completed.
