Title: Method for preventing scaling of piping
Inventor: KAWAMURA KAZUSHIGE
IPC: B08B3/08
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for preventing scaling of a piping for transferring liquid suspended with alkaline solid particulates. SOLUTION: A gypsum slurry is extracted from JBR 12 and is subjected to a sepn. of solid from a liquid to gypsum and filtrate by a device 14 for the sepn. of the solid from the liquid. The filtrate is then stored in a pit 16. The filtrate is ladled out of the pit and is transferred to the water collecting tank 20 of a final waste water treating device by a relatively long piping 18 for several minutes. The scaling arises in the piping 18 for transferring the filtrate. A hydrochloric acid injection pipe 22 is connected to the piping at the outlet of the pit 16 in this method and the piping is provided with a pH meter 24 for measuring the pH of the filtrate in the piping at the inlet of the water collecting tank 20.  This hydrochloric acid injection pipe 22 is provided with a flow rate control valve 26 for controlling the hydrochloric acid injection rate in accordance with the pH value measured by the pH meter 24 and a controller for controlling the flow rate control valve 26 in accordance with the pH value of the pH meter 24. The pH meter 24 detects the pH of the filtrate. The controller controls the injection rate of the aq. hydrochloric acid soln. by the flow rate control valve 26 so as to maintain the pH of the filtrate at the set pH in accordance with the measured value.

Title: Logarithmic amplifier circuit
Inventor: MATSUDA YOSHITERU
IPC: H03F3/08
Filed: 1984-01-26
Abstract: PURPOSE:To increase a dynamic range of a logarithmic amplifier circuit by applying the reference voltage of logarithmic amplifiers for logarithmic compression of each separated optical signal from a reference potential source of a differential amplifier to which the outputs of said logarithmic amplifiers via a voltage shift circuit. CONSTITUTION:The logarithmic amplifiers 32 and 33 give the logarithmic compression to color signals supplied from terminals 30 and 31. These color signals undergo the differential amplification by a differential amplifier 38. The reference voltage is applied to the amplifier 38 from a referance voltage source 49. At the same time, the reference voltages of amplifiers 32 and 33 are also applied to the amplifier 38 via a voltage shift circuit 50. The circuit 50 is set at a voltage shift about half the maximum forward voltage VDmax of diodes 35 and 34. Thus the control and setting of the reference voltage VB affect the reference voltage VS. Furthermore VS=VB+VOmax/2 is satisfied and therefor the currents of resistances 39 and 40 flow in both directions according to the light quantity. Thus the temperature change is stabilized. In this way, the dynamic range of a logarithmic amplifier circuit is also improved.

Abstract: PURPOSE:To image fine difference of absorption coefficient of a specimen, in examinating a specimen having large absorption coefficient, by lowering the transmitted data of an air layer and reducing the ratio of the transmission data between the specimen and the air layer. CONSTITUTION:Radioactive rays 10 are allowed to irradiate a specimen 43 from a radiation source 11 and detected by a detector 12. While e.g. X-rays or gamma-rays a shutter 13 made of lead or tungsten having high absorption coefficient is inserted.
