Title: Treatment of ferrous ion-containing mine water
Inventor: SANO MASAKATSU
IPC: C02F1/64
Filed: 1982-01-29
Abstract: PURPOSE:To form ferrite capable of effective use at an ordinary temperature, by adding Al salt to Fe<2+>-contg. mine water in which Si also exists, adjusting pH to coprecipitate formed Al(OH)3 together with an Si component, oxidizing the residual Fe<2+>-contg. liquid, and then converting the precipitate into a magnetic body. CONSTITUTION:By adding Al salt or an Al<3+>-contg. liquid and then an alkali agent to Fe<2+>-contg. mine water in which Si also exists, Si impeding the reaction of forming ferrite is coprecipitated together with Al(OH)3 formed at pH below 6 and separated. By adding an alkali agent to the Fe<2+>-contg. liquid after the separation, by liquid is held at pH above 7. Oxidizing gas such as oxygen or air is then blown to oxidize ferrous ion in the liquid until the relation of Fe(III)/Fe(III)=1.5-3.0 is satisfied. Thereafter, the liquid is left to stand or agitated in an unoxidizing atmosphere such as N2 to convert the precipitate into a ferromagnetic state (ferrite). Oxidizing gas is further blown into the liquid to oxidize Fe<2+>, and the formed precipitate is separated.

Title: Controlling valve
Inventor: MOROZUMI EIICHI
IPC: F16K31/12
Filed: 1981-01-31
Abstract: PURPOSE:To enable to control the pressure of fuel gas within an outlet passage by a method wherein the opening area of a port formed between an inlet passage and the outlet passage is changed in response to the position of a valve body regulated by an actuator. CONSTITUTION:When a driving signal is supplied from a driving circuit to an electromagnetic pump 22, the electromagnetic pump 22 pressure-feeds the liquid within a primary chamber 24 to a secondary chamber 25 to enhance the pressure therewithin. In response to the rise of said pressure, a responding body 27 moves downward. With the downward movement of said responding body 27, a valve body 1 moves downward against a spring 7, resulting in rendering the opening area of the port 5 larger. When the pressure within the secondary chamber 25 lowers, the valve body 1 ascends together with the responding body 27 by the action of the spring 7, resulting in rendering the opening area of the port 5 smaller. Owing to the movement of said valve body 1, the gas pressure within the outlet passage 4 is controlled and detected by a pressure sensor 6.

IPC: G01M11/02
Filed: 1982-02-01
Abstract: PURPOSE:To obtain an accurate pupil area independently of the variance of the light quantity level, by using light sources different in diameter and performing the measurement twice with different slice levels of a television signal to correct inclinations of luminance level curves mutually. CONSTITUTION:Pinholes P1 and P2 having radiuses r1 and r2 respectively are compatible with each other. The light from the pinhole placed in the focus position of a lens 1 to be measured projects the picture of a stop 2 of the lens 2 onto a screen 3. The projected pattern has the luminance level adjusted by an ND filter 4 and a transparent glass 6 and is projected onto the surface of a vidicon 9 by a taking lens 8. This projected pattern is swept by scanning lines to change the slice level for obtaining an electric signal. Pinholes are exchanged to obtain respective equivalent diameters of the pupil image for successive combinations of level change, and a true equivalent diameter of the pupil image is operated on a basis of the proportional relation between equivalent diameters of the pupil picture and obtained equivalent diameters, thus obtaining the F number of the lens.
