Title: Method for charging ore to smelting and reducing furnace
Inventor: MATSUO MITSUTAKA
IPC: C21B13/00
Filed: 1986-07-31
Abstract: PURPOSE:To charge ore with high addition efficiency to a furnace and to obtain a high reduction speed by dividing the ore to be charged at the time of smelting and reducing oxide ore to massive, small granular and powder ores and charging the ores by an adequate method meeting the respective grain sizes. CONSTITUTION:The ore to be charged to the furnace at the time of smelting and reducing the oxide ore by the interfacial reaction of a molten metal and slag is divided to the massive, small granular and powder ores. The massive ore is charged into the furnace from above and the small granular ore is charged therein from plural bottom blowing tuyeres 11 by using a carrier gas. The powder ore is charged into the furnace from plural side facing tuyeres 14 provided on the furnace wall by using a carrier gas. Since the powder ore is charged into the furnace so as to be orthogonal with the circulating flow of the molten metal circulating perpendicularly in the furnace, the powder ore contacts a metal bath 8 with the satisfactory stagnation time. The high reaction rate is obtd. and the smelting and reduction are executed with high productivity by the above-mentioned method.

The partition plate 28 is provided with a plurality of small holes 28a and further it has ear pieces 28b bent substantially in a horizontal direction at its upper and lower portions. A longitudinal recessed hole 20e arranged at a rear part 20b of the cylinder near a connecting part 20d is located at a position displaced by about 90 deg. in respect to a center of the combustion cylinder 20 against the partition plate 28. During combustion, a primary flame formed within the combustion cylinder 20 is vibrated and a pressure variation may occur within the combustion cylinder 20 due to this vibration, although the pressure variation is accommodated under a presence of the closed spacing formed by the partition plate 28 and the recessed hole 20e. Thus, occurrence of noise of high frequency caused by the pressure variation is prevented.

Title: Image display control method for ultrasonic diagnostic device and device therefor, and puncture guide jig and ultrasonic probe
Inventor: AIDA KAZUHIKO
IPC: A61B8/14
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To improve a certainty when a testee is punctured. SOLUTION: When punctual needle detecting sensors 21a, 21b and a puncture judging circuit 3 detect that a punctual needle N is introduced into a punctual needle guide groove M of a puncture use ultrasonic sensor 2, a display control is performed so that an ultrasonic image is not put into a frozen condition. Therefore, even if a puncture is started under the frozen condition, the frozen condition is released at the time when the punctual needle N is introduced into the punctual needle guide groove M. Even if a freeze key K1 is pushed during puncture, the ultrasonic image does not undergo the frozen condition. Therefore, it is always possible to puncture the probe into the testee under a live condition and a certainty of puncture is improved.

Filed: 1986-08-05
Abstract: PURPOSE:To restrain energy loss and improve working efficiency, by limiting the opening degree of a valve means for connecting a pump port to an actuator port on the low pressure side thereof, in the case when a negative load is applied on an actuator. CONSTITUTION:Pressure detectors 15, 16 detect both load pressures applied on the rod and head sides of an actuator 6 respectively.
