IPC: C02F1/46
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To make bacteria hardly produced in equipment arranged upstream from an electrolyzer and not to lower bactericidal force of hypochlorous acid containing electrolytic water by, after the discharge of the hypochlorous acid containing electrolytic water is finished, rotating a pump for a prescribed time in the backward direction to cause electrolytic water in the electrolyzer to flow backward to the upstream side. SOLUTION: After spaying is finished, when a manual switch 3 is depressed, the supply of electrolytic power to a non-diaphragm electrolyzer 1 is stopped to stop the operation of a sprayer 2. Then, according to a control program in a controller 9, through a pump driving circuit, reverse voltage is applied to a pump 7 for a prescribed time to rotate the pump 7 in the backward direction in the prescribed time. As a result, hypochlorous acid containing bactericidal electrolytic water in the non-diaphragm electrolyzer 1 flows backward, upstream from the nondiaphragm electrolyzer 1 to sterilize equipment arranged upstream from the non-diaphragm electrolyzer 1 such as a salt water feeding tube 11 of a harness 14, the pump 7, and a salt water tank 5. Therefore, the bactericidal force of the discharged hypochlorous acid containing acidic water is not lowered.

Title: Method for processing silver halide color photosensitive material
Inventor: KUREMATSU MASAYUKI
IPC: G03C5/395
Filed: 1984-04-17
Abstract: PURPOSE:To decrease the concn. of the fixing and bleach-fixing component in a stabilizing liquid and to obtain the stable processing method by processing a titled material while bringing the stabilizing liquid and an ion exchange resin into contact with each other and/or bringing the overflow liquid of the stabilizing liquid into contact with the ion exchange resin then using part thereof as the stabilizing liquid. CONSTITUTION:If the above-mentioned material is directly subjected to the stabilizing treatment without passing the same through a rinsing stage, all the stains are accumulated in the stabilizing liquid. The generation of the stains is thoroughly prevented by bringing the stabilizing liquid into contact with the ion exchange resin. The processing of the material while bringing the stabilizing liquid into contact with the ion exchange resin is executed by putting the ion exchange resin into a cloth bag or the like and adding such bag or the like directly into the stabilizing liquid tank vessel in which the photosensitive material is processed. The overflow liquid of the stabilizing liquid and the ion exchange resin are otherwise brought into contact with each other then the stabilizing liquid is taken out of the stabilizing liquid tank and is brought into contact with the ion exchange resin by a column method or mixing method, etc. separately from the tank vessel and thereafter at least part thereof is put into the tank liquid. The ion exchange resin is preferably brought into contact with the fixing liquid or bleach-fixing liquid after the contact with the stabilizing liquid and is then regenerated. Recovery of silver is also possible in the regeneration of the resin particularly in the case of an anion exchange resin.

Title: Continuous casting method of slab
Inventor: OOKUBO YOSHIO
IPC: B22D11/128
Filed: 1979-06-22
Abstract: PURPOSE: To reduce the cracking of a slab by acting compressive force in its lengthwise direction near at least the horizontal leveling area and applying drawing force in the width direction near the horizontal leveling point in the curved type continuous casting.  
     CONSTITUTION: Horizontal drive rolls 10 of a speed nearly coinciding with the casting speed are provided in front of the portion near the horizontal leveling point of e.g. a slab 9 having unfrozen portions and brake rolls 11 of a speed slower than the casting speed are provided behind the portion near the horizontal leveling point, to apply compressive action in the lengthwise direction to the slab between these rolls. In addition, the drawing force in the width direction is applied to the slab by three pairs of broadside vertical rolls 12 near the horizontal leveling point. The vertical rolls 12a, 12b are drive rolls which are the same in speed as the horizontal drive rolls and the vertical rolls 12c are brake rolls of a low speed which apply drawing force dividedly at plural positions. The leveling strain with low-head casting is relieved by the synergistic effect of the compressive action in the lengthwise direction of the horizontal rolls 10, 11 and the lateral screw-down action and compressive action in the width direction of the vertical rolls 12.

Abstract: PURPOSE:To eliminate discomfortable feeling for a rider when a cage is moved in a passage for transverse running by controlling a moving means so that the maximum value of acceleration and decelerattion in the case of detecting existence of a rider is made smaller than the case of no existence of a rider. CONSTITUTION:When a control device 40 judges existence of movement in the transverse direction on a moving route to move a cage 18 to a target floor, the cage 18 is moved up to a transversely movable floor, stopped with a linear motor for ascent/descent 54 and a braking device, and a linear motor 38 for rotating a rail is driven to make the rotating rail correspond to a guide rail for transverse movement. When a rider is in the cage 18, a linear motor 60 for transverse movement is driven so as to minify the maximum value of acceleration and deceleration applied on the cage 18, and controlled to stop the cage at a target passage for ascent/descent.

Filed: 1983-05-06
Abstract: PURPOSE:To prevent the spurious deterioration of wide band reception by controlling voltage variable capacity elements which are added to BPFs of the high frequency part of a radio receiver by the phase comparator output of a PLL, and varying the center frequency of the BPF. CONSTITUTION:In the radio receiver which has a local oscillator PLL synthesizer, an error signal is branched from the phase comparator 8 of the PLL; one is inputted to an LPF9 and the other is inputted to a control voltage generator 12. Voltage variable capacity elements 13, 14, and 15 are added to the BPFs 1, 2, and 3 of the high frequency part to allow variation in center frequency with a voltage, and the elements 13-15 are driven by the output of the generator 12. The error voltage of a comparator 8 varies in output DC voltage with the frequency, so the center frequencies of the BPFs 1-3 are varied with a local oscillation frequency. Thus, a wide band receiver is realized without deterioration of the spurious sensitivity, etc.
