Title: Vacuum degassing method for molten metal
Inventor: KIKUCHI YOSHITERU
IPC: C21C7/10
Filed: 1989-06-09
Abstract: PURPOSE:To produce a molten steel having excellent cleanliness by dissolving gaseous H2 into the molten steel, decarburizing the molten steel by the release of the fine bubbles of H2 by a pressure reduction, further blowing gaseous N2 and subjecting the molten steel to dehydrogenation deoxiation by the release of the fine bubbles thereof at the time of degassing and refining the molten steel by a vacuum degassing method. CONSTITUTION:Circulating immersion pipes 3a, 3b of an RH vacuum degassing chamber 3 are inserted into a ladle 1 contg. the molten steel 2. The gaseous H2 is simultaneously introduced from the immersion pipe 3a and is released in the form of the fine bubbles in the molten steel into the vacuum chamber to accelerate the decarburization reaction by the fluttering of the molten steel surface in the vacuum chamber at the time of subjecting the molten steel 2 in the ladle to the vacuum degassing treatment in the vacuum space of the vacuum degassing chamber 3 by blowing the gaseous Ar from the inside wall surface of the immersion pipe 3a. The gaseous N2 is then blown into the molten steel and the gaseous H2, gaseous O2, etc., remaining in the molten steel are removed at the time of releasing the gaseous N2 in the form of the fine bubbles into the molten steel. The high purity molten steel having extremely small contents of C, H2 and O2 is produced.

Title: Picture forming device
Inventor: MATSUI KAZUO
IPC: G03G21/00
Filed: 1982-08-23
Abstract: PURPOSE:To decide the life of a photosensitive drum by providing a power source to be replaced together with the drum when the drum is replaced, consuming the electric power of the power source in every rotation of the photosensitive drum, and comparing a reference voltage and the source voltage on the basis of the correspondence between the performance limit of the photoreceptor and the voltage level of the power source. CONSTITUTION:Switches 5 and 7 turn on and off in every rotation of the drum 1, and then the electric power consuming circuit consisting of a resistance 9 and a capacitor C consumes the electric power of the power source 3. A contact 6 shown in the 2nd figure is connected to one input terminal of a comparator 8 constituting a comparing circuit and the comparator 8 makes a comparison with the reference voltage Vc. The voltage of the power source 3 drops according to the revolving speed of the photosensitive drum 1. When the voltage of the power source 3 attains the preset reference voltage Vc matching with the durable circuit Cc of the drum 1, the comparator 8 sends out an output signal to display its deterioration or to stop the operation of a copying machine. Thus, an old photosensitive drum is replaced with a new drum together with the power source whose output voltage drops below the reference value. The new drum has a power source generating an output voltage higher than the reference voltage individually, so the deterioration display disappears and excellent pictures are obtained.
