Abstract: PURPOSE:To automatically carry out the test of an action margin caused by the fluctuation of a basic lock frequency by providing the 1st step instructing the stop of a basic clock signal, the 2nd step instructing the modification of a frequency and the 3rd step instruction resumption. CONSTITUTION:Receiving a request to modify the basic clock, a system control processor 3A outputs a command to stop the basic clock to a basic processor 2A through a processor bus 4. Next, the processor 3A outputs the command to modify the basic clock in the same way, and controls an oscillator signal 8b so that a multiplexer 6 can select an oscillator with the prescribed frequency among oscillators 5a-5c. Then the system control processor 3A outputs an instruction to resume the basic clock to a basic processor 2A through the processor bus 4. Thus a basic clock generator circuit 7 again outputs a basic clock signal 7a to control the basic processor 2A. Finally the system control processor 3A outputs a instruction, that is, an instruction to complete the modification of the clock, to the basic processor 2A.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent the impairment of visibility of a road-surface colored part, and also to prevent the impairment of sight due to the fading with the lapse of time of the colored road surface. SOLUTION: First, a two-liquid mixed type binder is mechanically sprayed on a desired road surface with 1.5 to 2.0kg/m<2> .

Title: Inspection device for tapered surface in cylindrical body
Inventor: SAITO NORIAKI
IPC: H04N7/18
Filed: 1990-02-14
Abstract: PURPOSE:To inspect at which position on the tapered surface of the cylinder body a defect is generated by lighting the cylinder body downward from one side of the cylinder body and reflecting its illumination light at right angles to the tapered surface. CONSTITUTION:A downward lighting device 4 lights the cylinder body 5 to be inspected from one opening and a reflecting member 6 which has a reflecting surface for reflecting the illumination light at right angles to the tapered surface is inserted from the other opening of the cylinder body 5. Consequently, the incident light from the downward lighting device is reflected by the tapered surface when the tapered surface has no defect and is specular, and then returned by the reflecting surface of the reflecting member 6 to the same position on the tapered surface to travel backward in the original incidence direction. If there is a defect in the tapered surface, on the other hand, the incident light is not reflected by the tapered surface, so the quantity of the reflected light decreases. The position of the defect in the tapered surface can be decided.

Next, the variation of the rolling load is computed on the basis of the programmed rate of lubricant supply, and the roll gap computed by the setup compensator 13 is corrected. Besides, the new roll speed is computed correspondingly to the variation of the value of mass-flow on the basis of the amount of used lubricant. This roll gap's set point is inputted to the roll gap adjuster 6, and the set point of the motor speed corresponding to the corrected rotational speed of roll is inputted to the speed controller 8. By this setup compensating method, the balance between the mass-flow of every stand is attained so that the breadth fluctuation, etc., at neighborhood of the tip of the rolled material is prevented.

IPC: C21B5/00
Filed: 1982-03-03
Abstract: PURPOSE:To spray water uniformly in a furnace top part without cooling the same concentrically in the stage of cooling the waste gases at the furnace top by changing over  valves of water spray nozzles provided in the various positions in the circumferential direction of the furnace top periodically at specified intervals thereby spraying the  water. CONSTITUTION:For example, 5 pieces of the above-described water spray nozzles 1-5 are used by each piece as shown in the figure in the following way: The water  spraying time for one water spray nozzle is set at 2min and the nozzles 1-5 are so  controlled as to be opened and controlled successively. In this case, the on-off solenoid  valve of the nozzle 1 is opened to spray water for 2min and upon closing of this valve,  the solenoid valve of the nozzle 2 is opened to spray water. Thereafter the solenoid  valves are operated successively to spray water with the nozzle 1 after the spraying of  water with the nozzle 5. As a result, the water can be sprayed uniformly on the layer  top surface of the blast furnace; therefore, heating and evaporation are repeated only  at the layer top surface and the down flow of water into the high temp. zone in the  lower part of the furnace is prevented. The generation of gaseous H2 by the reaction of water gas is reduced considerably and the damage of the side wall and bottom bricks  of the furnace is prevented.
