Title: Desiliconization and dephosphorization of molten iron
Inventor: NARITA KIICHI
IPC: C21C1/02
Filed: 1982-12-06
Abstract: PURPOSE:To effectively carry out desiliconization and dephosphorization, by a method wherein after reducing the content of silicon to not more than a fixed value by injecting the flux containing iron oxide together with a carrier gas into the hot metal in mixer car, Na2CO3 or Na2CO3 and iron oxide are injected together with the carrier gas without forcedly flushing the desiliconized slag. CONSTITUTION:The hot metal is desiliconized until the content of silicon becomes not more than 0.05% by injecting the powder flux containing iron oxide together with the carrier gas into the hot metal in mixer car preliminarily desiliconized to not more than 0.2% silicon content. It is more preferable to add iron oxide together with CaO, fluorspar, etc. to the powder flux.

The square root of said summed value, i.e. the value expressed in the figure is outputted. Where Ak is a modulating signal component at a sample point. Thus, it is possible to use a clock signal not in synchronizing with the demodulation of an AM signal, thereby making the constitution of a clock generating circuit 13 easy and enabling an FM signal to be demodulated.

Abstract: PURPOSE:To prevent Cr particles from diffusing from a first electrical resistor into an insulating film of a lower layer by forming the first electrical resistor on the insulating film. CONSTITUTION:In processing a silicon substrate 11 within a reactive sputtering apparatus, activated C particles and CrSi particles are combined and the particles reach a silicon oxide film 12 on the silicon substrate 11 and a CrSiC film 13 is formed. Subsequently, by processing the silicon substrate 11 within the reactive sputtering apparatus, the activated CrSi particles reach the CrSiC film 13 on the silicon substrate 11 and a CrSi film 14 is formed. Then, by a RIE using Cl2 gases, the CrSiC film 13 and the CrSi film 14 are removed by an etching using a resist pattern 15 as a mask, and first and second electrical resistors 13a and 14a made of the CrSiC film 13 and the CrSi film 14 are formed. Since film properties of the CrSiC film 13 are higher than that of the CrSi film 14 in density, the diffusion of Cr to an insulating film can be prevented to the utmost even under high temperature conditions when forming the CrSiC film 13 on the silicon oxide film 12.

Abstract: PURPOSE: To provide a pump for preventing a backward flow of fluid sucked within the pump chamber and reducing a remaining quantity of discharge. CONSTITUTION: First, only piston 64 is moved to the right side so that the volume is increased in the pump chamber 69 in order to generate a negative pressure in the pump chamber 69 and thus allow ink to be sucked.
