IPC: G06F3/00
Filed: 1979-08-01
Abstract: PURPOSE: To reduce the hardwares down to 1/n (n: number of input/output parts) and thus attain the reduction of cost, by changing the coupling of the signals between the input/output part and the control part into the serial type and then giving the electrical insulation to the serial signal.  
     CONSTITUTION: Input/output parts I/O 1Wn  coupling between control part CE 1  and the controlled unit are formed into blocks. For instance, DC operation power source VCC of part I/O 1  is made independent in circuit ad 1 , and furthermore insulating circuit I 1  is installed at control part CE 1  (installed hitherto at the side of input/output terminal Ti/O 1Wn ). Thus circuit I 2  suffices with one unit to attain its purpose satisfactorily and regardless of the input number by changing the signal transmitting method into the serial system between part CE 1  and part I/O 1 .

Title: Method for driving motor pump device and motor pump device
Inventor: KUBO SUEO
IPC: F04D15/00
Filed: 1994-05-11
Abstract: PURPOSE:To prevent damage of a shaft sealing means caused by inflow by preventing the inflow of pump handling liquid into a gas seal chamber. CONSTITUTION:The applying power source of a driving motor 15 is variably controlled by a rotational speed varying device 36, and an impeller of a pump part 11 is gradually accelerated to the rated speed while taking the specific time in starting. While, it is gradually decelerated to the rated speed while taking the specific time when the pump part 11 is stopped. Since sudden pressure fluctuation is not generated on the pump part 11, pump handling liquid is prevented from flowing into a gas seal chamber from the pump part 11. The pump is prevented from such failure that the pump handling liquid such as slurry contained liquid, crystalline liquid, high-viscous liquid, corrosive liquid or high-temperature liquid flows into a gas phase part of the gas seal chamber by the pressure fluctuation, and reaches the shaft seal part, thereby the damage is generated on the shaft seal part due to the deterioration of gas seal action, and a bearing is damaged. The long life of pump is achieved.

Title: Heat treatment in continuous annealing furnace
Inventor: HOSHI YOUNOSUKE
IPC: C21D11/00
Filed: 1985-05-10
Abstract: PURPOSE:To prevent the change of mechanical characteristics after annealing in the stage of annealing continuously a steel strip which is different in material quality in a continuous annealing furnace by changing the temp. of the furnace and changing simultaneously and adequately the traveling speed of the steel strip before the succeeding steel strip enters the heating furnace of the annealing furnace. CONSTITUTION:The steel strip 1 is annealed in a heating zone 8, a soaking zone 3 and cooling zones 4, 5, 6. The temp. of the heating zone 8 is changed before the succeeding steel strip having a change in the thermal load necessary for the intended annealing enters the heating zone 8 if the thickness or width of the steel strip to be annealed changes and when a change arises in the heat capacity of the steel strip. The temp. of the heating zone is thereby so controlled as to attain the stationary temp. at the point of the time when the succeeding steel strip enters the heating zone 8. The line speed for the strip 1 is set at the value corresponding to the conditions after the change of the necessary heat load simultaneously with the above-mentioned temp. change and further the hot air is injected from nozzles in the zone 8 to the steel strip before the change of the necessary load. The mechanical characteristics after the annealing do not change even if the thickness, width, etc., of the preceding and succeeding steel strips change. The mechanical characteristics are thus maintained at the target value.
