Abstract: PURPOSE:To conveniently and industrially remove the ferric ion and iron hydroxide sludge in an iron-based electroplating soln. by lowering the pH of the soln. in a settling tank to convert the ferric ion to ferric hydroxide which is settled and transferring the supernatant water to a storage tank. CONSTITUTION:The iron-based electroplating soln. is settled in the settling tank 1, and the pH is adjusted to 2 to <3.5 to convert ferric ion to ferric hydroxide which is settled. Samples are collected from sampling ports 3 arranged in the depth direction, the ferric ion concn. is measured by a turbidimeter 4, the depth at which the plating soln. is sucked is judged by a central processing unit 5, and the instruction is sent to a suction controller 6. A suction port 7 is positioned at an appropriate depth by the controller 6 based on the instruction, and the plating soln. at the upper layer in the settling tank 1 is transferred to the storage tank 2 by a suction pump 8. When the concn. of the ferric hydroxide sludge in the lower layer in the settling tank 1 is increased, an instruction is sent to a filter 9 from the central processing unit 5, the filtrate and the sludge are separated, and the filtrate is sent to the storage tank 2.

Filed: 1989-06-08
Abstract: PURPOSE:To enable high precise temperature gradation control to be performed by a method wherein a means which controls an electrification duty ratio in a unit electrification cycle so that temperature of a thermal resistant element is varied by an optional characteristic in point of time, is established. CONSTITUTION:Thermal resistant elements R1 to R521 are selectively electrified to be heated in a unit electrification cycle DELTAT according to an information content of each corresponding bit. A radio of electrification time tE to unit electrification cycle DELTAT, i.e., an electrification duty ratio is not constant (fixed) through an electrification interval, and is varied each unit electrification cycle according to each level of density gradation under control of a CPU 40. Thereby, the thermal resistant element reaches minimum recording temperature TS in shortest time. Therefore, though electrification time is short (for instance, T2), required density (d2) corresponding thereto is obtained. Further, though electrification time continues, temperature is kept almost constant. Thereby, even when electrification time is short or long, required density corresponding each thereto is obtained. Besides, relation between a number of times of electrification and recording density becomes a linear proportional relation, and high precise density gradation control becomes capable of being performed.

Abstract: PURPOSE:To make it possible to produce a non depletion condition on the surface and reduce the generation of dark current by burying negative charge in an insulation film on a first region which constitutes a photo transfer device. CONSTITUTION:A negative charge region 6, where negative charge is buried in a silicon oxide film 5, is buried. The negative charge region 6 is positioned in the upper part of an n type semiconductor layer 2, which serves as a first region which constitutes a photodiode. When aluminum ions are implanted into the silicon oxide film, negative fixed charge is produced. Therefore, after a gate electrode 7 is formed, if aluminum ions 9 are implanted, using resist 10 as a mask, it is possible to form the negative charge region 6 on the n type semiconductor layer 2 in terms of the gate electrode 7 on a self alignment basis. When negative charge 11 is present in the silicon oxide film 5, the potential on the surface of the n type semiconductor layer 2 is hoisted by the amount of electric charge. When its potential is increased more compared with the potential of the p type semiconductor substrate 1, positive holes flow in from the p type semiconductor substrate 1 so that the surface of the n type semiconductor layer 2 may turn into a positive hole accumulated layer, thereby forming a p type inversion region 8 and eliminating depletion.
