Abstract: PURPOSE:To hold the gradient of the liquid composition of processing liquid in each processing chamber and to improve cleaning effect by a small-sized device by interrupting the flow of processing liquid between a 1st and a 2nd area substantially by installing a partition member. CONSTITUTION:Both end parts 171 and 172 of the partition member 17 which is installed in a rack 3 are tapered and both corresponding side walls 21 and 22 of a processing tank 2 are tapered at the same angle. Consequently, when the rack 3 is inserted into the processing tank 2, the end parts 171 and 172 of the partition member 17 engage the internal surfaces of the side walls 12 and 22 of the processing tank 2 to partition the 1st area 18 which includes processing chambers 6A and 6B where a photosensitive material S passes firstly and the 2nd area 19 which includes processing chambers 6E and 6D where the photosensitive material S passes finally. At this time, the engagement parts is brought into close contact by the weight of the rack 3 itself to stop the run of processing liquid substantially. Consequently, the liquid composition gradient of the processing liquid in each processing chamber is maintained and the throughput is improved; and the device is miniaturized and the consump tion of the processing liquid is reduced.

Title: Displacement-speed detector
Inventor: YAMANOUE KOUICHI
IPC: G01P3/488
Filed: 1989-09-27
Abstract: PURPOSE:To make it possible to detect the speed at any position of a moving body by arranging magnetizing means for forming the different magnetic poles at symmetri cal positions with respect to the center of the annular moving body, and arranging means for detecting magnetic fluxes passing the inside in the perpendicular direction to the magnetizing direction. CONSTITUTION:A coil bobbin 12 which is held with a bearing 15 and a housing 11 has the entire shape of a cross pattern viwed from the upper surface. A core 13 is provided in the inside of a pair of facing projections so as to penetrate the projections. Coil parts 121a and 121b are provided at both end parts of the core 13. When pulse current is made to flow through the coil parts, two facing parts X1 and X2 in the direction of the diameter of a rotor ring 23' which is an annular moving body are magnetized at the same time. Thus the different point magnetic poles are formed. Coils 122a and 122b are arranged at the other pair of projection parts of the bobbin 12 in the perpendicular direction to the magnetizing direction. The coils detect the leaking magnetic fluxes from the point magnetic poles, i.e. the internal passing mag netic fluxes. Since the magnetic fluxes are changed in response to the rotating angle of the ring 23', the rotating speed of a rotor 2 wherein the ring 23' is arranged can be detected based on the magnetic fluxes.

Abstract: PURPOSE: To avoid execution from being disabled due to memory overflow by re-distributing in the horizontal direction impurities registered in rectangles comprising a cell, and registering newly determined amounts of impurities in polygons corresponding to the rectangles. CONSTITUTION: A cell taken out is divided into polygons in accordance with the substance boundaries present in the cell, and the area and the gravity center of each of the polygons are calculated.

The resultant rectangles are arranged in the order of the position in the horizontal direction of the gravity center of the respective polygons corresponding to the rectangles. Amounts of impurities, registered in the arranged rectangles in Q4, are registered in the corresponding rectangles (Q6). The distributions of impurities of strips in the horizontal direction, converted into one-dimensional structure in Q6, are re-distributed in the horizontal direction for each rectangle.  The amounts of impurities included in the rectangles are registered in the original polygons corresponding to the rectangles.

Filed: 1988-10-03
Abstract: PURPOSE:To enlarge the available voltage range with low cost by inserting a current limit circuit, where one or more sets of parallel circuits of a constant current diode and a constant voltage diode are connected in series, between a bridge rectifier and a power source capacitor. CONSTITUTION:A current limit circuit 19 has a constant current diode 17 and a constant voltage diode 18 connected in parallel. When a DC power source 21 is connected with the current limit circuit 19 and the voltage E of the power source 21 is increased, current I1 flows through the constant current diode 17 and when it reaches the rated value it is maintained at the rated value regardless of the increase of the voltage E. When the voltage E increases furthermore, the voltage of the constant current diode 17 reaches the rated voltage of the constant voltage diode 18 and current I2 starts to flow through the constant voltage diode 18 and the voltage across the constant voltage diode 18 is maintained at approximately a constant level. The more the number of set of the parallel circuit of the constant current diode 17 and constant voltage diode 18, the wider the range where the voltage E is constant against the load current IL.

Title: Lowered stock level operation in blast furnace
Inventor: MATSUBARA SHINJI
IPC: C21B5/00
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To adjust the temperature of furnace top gas without developing the blowoff of the furnace gas and the furnace cooling by gradually reducing the charge of raw material at the first half of the start in a lowered stock level operation, continuing the charge of raw material without fully stopping and specifying the stock level, lowering speed. SOLUTION: The stock level lowering is executed while continuing the charge of raw material into a blast furnace until the charged material level in the furnace comes to the height in the range of 0.3-0.5 times of a distance between a stock line and a tuyere below the stock line. In the lower part of the charged material level in the furnace than the above level, the charge of the raw material is stopped to execute the stock level lowering. The raw material charging quantity is adjusted so that the stock level lowering speed during continuing the charge of the raw material comes within the range of 0.8-1.5 m/h. Further, during the lowered stock level operation, water is sprayed from the furnace top part to restrain the heat-up of the furnace top gas temperature to the upper limit target value, e.g. <=400 deg.C.  In this way, such accident as to flood into the furnace developed in the case the heat exchange with the furnace gas is not normally executed, is prevented and also, the development of the furnace cooling is prevented.
