Title: Operation of refining furnace in copper smelting
Inventor: MARUYAMA TSUNEO
IPC: C22B15/14
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To shorten the operation time of a furnace by blowing the air and heavy oil from a tuyere in the furnace at setting flow rate according to sulfur concentration at the initial stage of crude copper, changing the flow rate of the air and the heavy oil into a prescribed value after the sulfur concentration in molten metal lowers to a target value and succeeding the blowing until oxygen concentration in the molten metal lowers to a target value. SOLUTION: In the initial stage, the flow rate of the air and the heavy oil blown from the tuyere is desirable to set so that the air ratio becomes <1, from the viewpoint, that suitable stirring energy is given, and the heavy oil is suitable made to incomplete combustion in the molten metal for pre- deoxidation. Then, after the sulfur concentration in the molten metal lowers to the target value, the flow rate of the air and the heavy oil is desirable to change so that the air ratio becomes smaller than the value at the initial stage from the viewpoint, that the deoxidation is promoted by sufficiently supplying the reducing gas. In this way, since the desulfurization and the reduction are simultaneously progressed by executing the predeoxidation together with the desulfurization since the initial atage, the necessary time for the deoxidation is drastically shortened.

Title: Communication processor and method for adjusting its received clock frequency
Inventor: OGAWA KUNIHIKO
IPC: H04L1/00
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To adjust the frequency of a received clock signal on-line. SOLUTION: When a reception signal 9 is received, a reception detection circuit 3 outputs a reception detection signal 7. An IC 2 for communication processing converts the signal 9 into reception data, and when an error exists in the reception data, a communication error signal 6 is outputted and remains as it is. A CPU 1 changes the frequencies of a received clock signal by setting another frequency in an internal register 10 when the signal 6 is outputted and remains as it is. When the IC 2 for communication processing releases the output of the signal 6, the frequency set in the register 10 is defined as a normal frequency of the frequency of the received clock signal.

Title: Photosensitive material processor and processing method for photosensitive material
Inventor: KUROKAWA TOSHIO
IPC: G03D3/00
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To provide a photosensitive material processor capable of suppressing the evaporation and deterioration of a replenisher solution. SOLUTION: A water absorbing polymer 32 having 35 deg.C temperature sensing point is stuck to a passage 30 in each processing tank of a processor such as a color developing tank 12. When the operation of the processor is suspended for a long time at night, the polymer 32 approaches room temperature (<35 deg.C), absorbs a processing solution, swells and blocks the passage 30. The evaporation and oxidative deterioration of the processing solution are therefore suppressed. When processing is carried out, the processing tank is heated with a plane heater 34. Since the polymer 32 discharges the absorbed processing solution and shrinks at a temperature above the 35 deg.C temperature sensing point, a film can be processed.
