Title: Power source provided with redundancy
Inventor: INAO KIYOHARU
IPC: G05F1/00
Filed: 1978-03-10
Abstract: PURPOSE: To decrease the dip of output in case of the change-over of trouble while reducing calorific value, by butting the output ends of a plurality of stabilizing power sources, by connecting the output ends in common through diodes and by suaring load to each power source.  
     CONSTITUTION: The output ends of stabilizing power sources 1, 2 are connected to load in common through diodes D, and the outside signals of the diodes D are fed to error amplifiers A through cut-off preventive circuits CT, thus controlling regulators REG. Meanwhile, load-share control circuits LOD compare the output current display signals of the stabilizing power sources 1, 2 and load-share signals sent from a signal line LIN, and control the error amplifiers A. Thus, only the other power source independently functions when there happens trouble in one power source, and the dip of output voltage during the time can be decreased while calorific value can be reduced because the loss of power is dispersed into two power sources when normal.

Title: Method and device for electrolysis by electrode provided with fluid permeation function
Inventor: TOMIOKA HISASHI
IPC: C25D17/00
Filed: 1981-02-26
Abstract: PURPOSE: To absorb and separate the gaseous bubbles produced on the liquid contact surfaces of an electrode and to assure normal electrolytic treatment conditions in an electrolytic device or the like for forming an anodized film by using a material which is well conductive and is permeable of fluid for a counter electrode.  
     CONSTITUTION: In a main cell 1 of an electrolytic cells for applying anodic oxidation treatment, etc. on Al, a fluid-permeable electrode 3 of a porous carbon material or the like which is well conductive and is permeable of fluid, is disposed as a counter electrode for an object to be treated. The bubbles of gaseous hydrogen are produced on the liquid contact surfaces of the electrode 3, but the greater part of the produced gases are permeated and absorbed in the cylindrical inside part of the electrode together with the electrolyte 2 around the same by the characteristics of the porous structure of the electrode 3. Thereby, the gaseous bubbles around the electrode 3 are captured just prior to floating, and the release thereof into the atmosphere from above the cell 1 is decreased drastically. The electrolyte 2 separated of the produced gases is reflowed into the cell 1.

Title: Production of synthetic resin particle having functional group on its surface
Inventor: OOTSUKA YASUJI
IPC: C08F2/18
Filed: 1981-02-26
Abstract: PURPOSE: To obtain easily filtrable synthetic resin particles having functional groups on their surfaces at higher densities, by suspension-copolymerizing a hydrophobic monomer having a plurality of unsaturated groups with a hydrophilic monomer having functional groups.  
     CONSTITUTION: A hydrophilic polymerization initiator is dissolved in a hydrophobic monomer having at least two unsaturated groups (Ma). The resulting solution is added to a medium, e.g., water, and heated with agitation. Thereby, Ma polymerizes and gels into spherical particles while it is maintained in the form of sphere dispersed in water. If is preferred that this polymerization reaction is stopped at the stage at which the spherical gel particles contain at least 5wt% unreacted Ma monomer (prepolymer gel particle). Next, a hydrophobic monomer containing functional groups (Mb) is added to an aqueous suspension of said prepolymer gel particles and the mixture is copolymerized under agitation. It is preferred that the amount of unreacted monomer remaining in the prepolymer gel particles is not higher than 95%. This makes it possible to obtain a particulate polymer having a uniform and desired particle size.

Title: Optical scanner
Inventor: SHIBATA ISAMU
IPC: G02F1/33
Filed: 1980-03-05
Abstract: PURPOSE:To obtain the image recording always stable, by detecting the output of acousto-optical modulator which superimposes the image information given externally on the output light of a gas laser and controlling the feedback control of the gas laser driving circuit so that the output can always be constant. CONSTITUTION:Since the zero-order diffracted light of an acousto-optical modulator 5 is proportional to the amount of light of the primary diffracted light actually used for the write-in light, the driving control of a gas laser 1 is made with a peak voltage according to the amount of light of the zero-order diffracted light detected and stored in the peak holding circuit 13. Thus, the light for write-in can always be constantly stored. Further, by also detecting the zero-order diffracted light of the modulator 5 with the photodetector 11, the recording of image can be made without giving any hindrance to the optical path of the primary diffracted light.

Title: Energization method in electrolytic refining
Inventor: ANDO KOJI
IPC: C25C1/18
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To suppress the degradation in current efficiency and improve an electrodeposited surface state by setting specified pause time at the time of changing over a forward direction to backward direction. SOLUTION: The pause time in changeover of forward and backward energization in electrolytic refining of metal is 30 to 100 seconds and the changeover of current directions is executed at a ratio of once every 15 minutes to 1 hour, by which the occurrence of an anode passive state is prevented and the degradation in the current efficiency is minimized. The degradation in the current efficiency occurs in the instantaneous shorting by the reversing of the current in the electrified layer of the cathode surface, in addition to the dissolution of the cathode. Then, the electrodeposition progresses even during the discharge time and the degradation in the current efficiency is effectively prevented if the current direction is reversed after the electrified layer is discharged with the pause of the specified time.  The reason thereof conceivably lies in that the required metallic ion concn. is restored by natural convection and diffusion while the electrified layer is not annihilated right after the service interruption.
