Title: Condensate filtration using hollow fiber membrane
Inventor: SUNAOKA YOSHIO
IPC: G21C19/307
Filed: 1988-09-19
Abstract: PURPOSE:To carry out filtration stably in condensate filtration wherein condensate is infiltrated from outside to inside of a hollow fiber membrane by forming a thin coating of a fine powder of a cation-exchange resin and/or a fine powder of a chelating resin on the surface of each hollow fiber membrane. CONSTITUTION:A hollow fiber module 1 comprised of bundled many hollow fiber membranes is placed in a filtrating tower 9 and condensate filtration is carried out by infiltrating the condensate from outside to inside of each hollow fiber membrane. At that time, before the condensate is flowed, water containing a fine powder of a cation-exchange resin and/or a fine powder of a chelating resin is infiltrated into the hollow fiber membranes to form a thin coating of the fine powder of a cation-exchange resin and/or a fine powder of a chelating resin. Then, the condensate is infiltrated into each of hollow fiber membranes through the thin coating. As a result, ferric ion in condensate and copper ion accelerating oxidation of the ferric ion are prevented from having a direct contact with the hollow fiber membranes so as to prevent pollution of the membranes and filtration is carried out stably.

Inventor: MIYAWAKI SHOICHI
IPC: D21C9/10
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To efficiently decolorize and decompose a waste bleaching liquid for pulp in a short time by using a specified kind of microorganism having high oxidation decomposing activity and reducing activity for lignin.

Title: Method for driving optical modulating switch
Inventor: GOHARA YOSHIHIRO
IPC: G02F1/133
Filed: 1985-10-18
Abstract: PURPOSE:To operate supply optical modulating switches in a minimum time by holding an optical modulating material having the bistable property between electrodes and applying a voltage continuously until inversion of the stable state is detected. CONSTITUTION:The state of a corresponding picture element is read out from a memory 6 in accordance with inputted picture element data and is compared by a data comparator 7. If this comparison results in coincidence, the picture element is set to the non-selected state as it is; but if it results in discaccord, the voltage which inverts the stable state is applied to the picture element and the memory is rewritten. This voltage is applied continuously until inversion is detected by an inversion detecting circuit 11, and application of the inverting voltage is stopped to scan the next scan electrode when inversion is detected. This operation is repeated to drive optical modulating switches in a matrix. Since the inverting voltage is applied to only picture elements where the stable state should be inverted, the operation speed of switches is raised twice in comparison with the conventional speed.
