Title: Manufacture of steel containing chromium in electric furnace
Inventor: MIYANO HARUO
IPC: C22C33/04
Filed: 1986-11-19
Abstract: PURPOSE:To rapidly manufacture a steel contg. Cr when a molten metal is refined by generating arc between electrodes and the molten metal, by using Cr ore as a Cr source in combination with a reducing agent. CONSTITUTION:Three rod-shaped electrodes 3 are vertically placed in an electric furnace 1 through the cover 2. Starting material such as scraps and a flux such as fluorite or silica sand are charged into the furnace 1 and three-phase AC voltage is impressed to the electrodes 3 to generate arc 4 between the electrodes 3 and the scarps. The charged materials are melted by the arc 4 to obtain a molten steel 5 and slag 6. Cr ore and coke are then fed from a tank 9 and blown into the arc 4 from a nozzle 8 with compressed air as a carrier. Coke may be added separately from Cr ore. After the end of blowing of Cr ore, gaseous Ar is introduced into the molten steel 5 through a lance to agitate the molten steel and the molten steel is tapped into a ladle. During the tapping, ferrosilicon is added to the ladle and the molten steel is agitated with gaseous Ar.

Title: Isolation switching device
Inventor: MIZUNO CHIAKI
IPC: H01L29/80
Filed: 1985-12-09
Abstract: PURPOSE:To realize an isolation dielectric strength suited to a limited space and a high temperature-resistance by using junction field effect transistors (TRs) whose gate oxide film thickness is set to 7,000Angstrom -1mum so as to constitute a bridge circuit and providing a resistor to at least one of the TRs. CONSTITUTION:When the input signal of logic 0 is inputted (switch 26 is opened), each source-drain voltage of the junction field effect TRs 21-24 constituting the bridge circuit is made equal and a potential difference between bridge output terminals (a, b) is '0'. An analog signal processing circuit 28 discriminates the state and outputs logic '0'. When the input signal of logic '1' is inputted (switch 26 is closed), a gate potential different from other gate potentials is fed to the TR 21 by a resistor 25, a potential difference is produced between the output terminals of the bridge circuit, the state is discriminated by the signal processing circuit 28 to output the signal of logic '1'. In selecting the gate oxide film of the TRs 21-24 as 7,000Angstrom -1mum, the dielectric strength of nearly 100V is guaranteed.

Title: Method for measuring radioactive rays by correcting counting loss
Inventor: GOTO YOSHIMI
IPC: G01T1/17
Filed: 1985-12-09
Abstract: PURPOSE:To make it possible to certainly measure radioactive rays even in the case of a high radiation level, by a method wherein a radiation detecting pulse is converted to a radiation detecting pulse of a non-paralysis model before counted by a counting rate meter but the counted value is automatically corrected on the basis of a dead time zone. CONSTITUTION:The radiation detecting pulse from a detector 1 is amplified to a predetermined level by an amplifier main body 2-1 to be compared with a definite level TH by a comparator 2-2. The radiation detecting pulse from which noise was removed receives the predetermined shaping of a wave form by a wave form shaping circuit 2-3 and the number of said pulses per a unit time are automatically counted by a counting rate meter 3 to receive predeter mined correction. When counting omission is generated, a dead time for (T1+T 2)sec is generated per one radiation detecting pulse and counting becomes impos sible for n.(T1+T2)sec using the counted value n(cps) of a counting rate for 1sec. Therefore, the conversion to a true counting rate (r) is performed by r=n{1-n(T1+T2)}.
