Title: Method and device for charging raw material to melt reducing furnace
Inventor: HAMADA SHIYUNJI
IPC: F27D3/10
Filed: 1983-02-07
Abstract: PURPOSE:To make the temp. of the top gas of a melt reducing furnace high and decrease the thermal load in the furnace wall part, to extend the life of the refractory material used for the furnace wall, by charging respectively separately the coarse grain raw material among preliminarily screened raw materials into the central part of the furnace and fine grain raw materials into the peripheral wall part of the furnace from the top of said furnace. CONSTITUTION:A preliminarily screened coarse grain raw material 5 is charged from the top of a melt reducing furnace 1 into the central part of the furnace 1 through a hopper 3, and a fine grain raw material 4 is charged through the hopper 2 to the peripheral part of the furnace 1. Powder oxide is blown from the lower part into the furnace 1 packed therein with a carboneous material such as mainly coke or the like to induce a reduction reaction and the resulting product of the reaction thereof is taken from the furnace bottom during this time. The resistance against the rise of the gas in the furnace in the central part of the furnace 1 is decreased by the above-described charging method for raw materials thereby decreasing the pressure drop, and central flow is formed in the gaseous flow in the furnace. On the other hand, the flow rate of the gas is decreased in the furnace wall part and thermal load is decreased. The furnace top gas is thus made high in temp. and the life of the refractory material used for the furnace wall is extended.

Title: Laser driving equipment
Inventor: KAMIYA ATSUSHI
IPC: H01S5/042
Filed: 1994-02-15
Abstract: PURPOSE:To detect the deterioration of a laser diode, by forming an output part for leading out a feedback signal to the outside, and checking whether the feedback signal exists and the value of a signal. CONSTITUTION:An upper limit value of the signal value of a feedback signal is set in a selfdiagnostic circuit 7, which compares the signal value of the feedback signal with the upper limit value. When a laser diode LD is deteriorated, and the signal value of the feedback signal increases and exceeds the upper limit value, an abnormal signal is generated. That is, the upper limit value is set in accordance with the signal value of the feedback signal at the time when the laser diode LD is deteriorated. The abnormal signal is outputted to the outside from an output terminal O. Thereby the deterioration of the laser diode LD can be known. When an apparatus mounting a laser driving equipment has gotten out of order, it can be easily recognized whether the disorder is caused by the laser diode LD, by checking whether the abnormal signal is generated.
