Title: Projected/received signal processor
Inventor: IZUKAWA KAZUHIRO
IPC: G01S17/10
Filed: 1988-06-24
Abstract: PURPOSE:To enable the obtaining of a reception output resistant to a noise by driving a projection means by a charp signal with a frequency thereof varying linearly to convert reflected light from an object into a pulse compressed signal. CONSTITUTION:A reference signal generator 1 inputs a square wave signal into a transducer (Td)2 while a gate waveform is applied to a delay circuit 15. Output electrodes of the Td 2 are varied in interval with a wavelength and have a characteristic of picking up a higher frequency component for the electrode closer to the input signal. With such an arrangement, the output of the Td 2 gives a charp signal with a frequency thereof varying linearly to modulate a signal light of an LED 5 through a buffer 3. Then, the signal light is reflected on the object to be incident into a phototransistor 7 and turned to a voltage signal to be inputted into a Td 9 through a buffer 8. Thus, as the Td 9 has the intervals of the input electrodes varied with a wavelength, an input waveform is converted into a pulse compressed waveform to be outputted and the amplitude of an output waveform is expanded to narrow a pulse width thereby achieving a better S/N ratio.

Title: Accelerating method for dephosphorization in bottom-blown converter refining
Inventor: NOZAKI TSUTOMU
IPC: C21C5/34
Filed: 1978-12-19
Abstract: PURPOSE:To accelerate the dephosphorization in a converter, by utilizing converter slag powder mixed with Fe2O3 for refining of steel in a bottom-blown converter. CONSTITUTION:The slag formed during steel refining in a bottom-blown converter is solidified, finely pulverized, mixed with Fe2O3 powder and quick lime powder, and is blown into the molten steel through a bottom tuyere using refining oxygen as a carrier gas. Nearly a half of the mixed slag is blown into the molten steel until C content of the molten steel is decreased to about 1%. When the C content is decreased to about 0.3%, the residual mixed slag is blown into the molten steel. FeO content of the molten steel and the molten slag is increased with Fe2O3 contained in the blown slag, and the dephosphorization of the molten steel is accelerated by the formation of stable CaO,P2O5 in the molten steel without reduction of P2O5, which is formed by the oxidation of P, with C contained in the molten steel. Because the mixt. contains the powdered converter slag as a main component, it makes slag quickly, accelerating the dephosphorization.
