IPC: C02F3/34
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a dephosphorization treatment device in which phosphorus removal is performed effectively and stably. SOLUTION: The dephosphorization treatment device D is incorporated into a miniature combined type Johkaso and equipped with an elution tank 39, iron electrodes 40, 41, a DC power source 42 and a control part 43. Iron ions reacting with phosphoric acid are eluted from the iron electrodes 40, 41 by electrolysis. The control part 43 performs control of current impressed between the electrodes 40, 41. Furthermore, an agitation mechanism 45 for agitating treatment water of the inside of the elution tank 39 is provided in the dephosphorization treatment device D. The agitation mechanism 45 prevents a reaction product formed in accordance with progress of electrolysis from being stuck on the surfaces of the electrodes 40, 41.  Or, promotion of electrolytic reaction is performed by stirring up the reaction product deposited on the bottom of the elution tank 39 so that the reaction product is allowed to easily flow out of the elution tank 39.

IPC: G03G15/04
Filed: 1983-08-05
Abstract: PURPOSE:To perform interruptive operation without restraint and to improve operability by taking an interruptive copy only by inserting originals successively into a dedicated original insertion slot provided separately from a normal original stack tray. CONSTITUTION:When an extra-original start signal is sent from a copying machine frame after an original is exposed for the final copy of a set number of sheets, an original on platen glass 37 is discharged to a paper discharge tray 28. Then, a next original in a wait state is fed to the original reference position of the platen glass 37. Then, a copy start signal is sent to the cpoying machine frame and the copying operation is restarted. When this copying operation is completed, the 1st copy original is copied. Thus, an interrupting user performs interruptive operation without troubling himself or herself about the interrupted user, so the utilization rate of the whole system is improved.

Abstract: PURPOSE:To prevent the variation in the area resistivity of an operation region by attaching electrodes or wirings to the operation region of a compound semiconductor substrate, and covering the part which is not covered with the electrodes or wirings with a light shielding film. CONSTITUTION:Si ions are implanted to a semi-insulating GaAs film 1, a protective film is covered, heat treated, and activated, thereby forming an N type layer 2.
