Title: Method and apparatus for discharging pressure-floating concentrated solid
Inventor: ITOU KAZUYUKI
IPC: C02F1/24
Filed: 1980-02-07
Abstract: PURPOSE: To discharge concd. solids without agitating solid layers by raising the interface of the concd. solids and discharging the extremely thin layer of the solids at the discharging of said solids.  
     CONSTITUTION: Sludge, particularly sludge 1 produced in activated sludge treatment and pressurized water 2 are mixed and are introduced into a floating tank 7. The extremely fine bubbles produced by reducing the pressure of the pressurized water stick to the solids in the sludge and float the solids, thereby separating the same to concd. solids 4. If at the discharging of these the level of a weir 22 is raised, the overflowing water level 6 of the treated water rises and along with this, the solids 4 begin to rise. However, the solids 4 are poor in fluidity and have thickness as well and therefore the rising rate of the interface is low and the interface rises approximately uniformly. As the interface rises, the solids 4 are scraped by a blade 24 which is being driven, successively from the upper part, and they are discharged through a discharge port 13. The blade 24 is provided on the same level as the opening part of the port 13 or slightly above this; hence, a mechanism for vertically moving the same is not necessary.

Title: Oxygen concentration
Inventor: MATSUI SHIGEO
IPC: C01B13/02
Filed: 1982-01-29
Abstract: PURPOSE:The adsorption bed is kept equal in pressure to other beds and the concentrated gas is introduced and, after completion of adsorption under pressure, the pressure is made equal and the concentrated gas is released to other beds, these operations are repeated to save the electric energy consumption. CONSTITUTION:In the pressure cycle process, the adsorption bed A at the atmospheric pressure is evacuated through valve V-5, pressurized with the product gas through valve V-3 to equalize its pressure to that of the adsorption bed C so that the high-concentration gas remaining in the adsorption bed C is recovered through valve V-16. Then, a mixed gas is introduced through valve V-1 into the adsorption bed A to raise the pressure in the adsorption bed A gradually to collect th product gas adsorbed through valve V-2. When the adsorption process at the adsorption bed A is finished, the introduction of the mixed gas is stopped, the pressure in the bed A is made equal to that in the bed B through valve V-4 and the high-concentration gas remaining in the bed A is released to the bed B. Then, the pressure in the bed A is reduced to the atmospheric pressure through valve V-6 to start the evacuation process again and continuous operations are conducted.

Abstract: PURPOSE: To reduce the effect of thermal noise due to source resistance and to increase the circuit gain, by attaching the constant current source supplying a given current other than the drain current to the source resistor and taking the current of constant current source adjustable.  
     CONSTITUTION: The constant current source 1 is attached and the constant current I o  is fed to the source resistor R s  in addition to the drain current ID. Further, the R o  line corrected with the constant current source 1 is as shown in the solid lines in the input and output transmission characteristics curve. When the resistor R s  is selected so that the drain current of the element having the characteristics B at the constant current I o  can be ID 1 , by parallelly moving the constant current value adjusted to I o ' to the line R s  represented in the dotted line in Figure, the drain current of element having the characteristics A can also be made equal to ID 1 . That is, since the voltage drop of the resistor R s  is produced with ID+I o , while taking the value of resistor R s  as small value and the slope of the correction line R s  greater, the value of the output voltage can be kept constant independently of the dispersion in FET. Accordingly, the production of thermal noise due to the resistor R s  and the lowering of the gain can be reduced.

After the shaft 2 is pushed and tilted by a cylinder 4, an X-table 17 is caused to slide by a pulse motor 19 until the accessory  bearing 6 comes into cntact with the shaft. At the time of the contact, the displacement is measured by a Magnescale 20. Such operation is effected again to tilt the  shaft 2 is the opposite direction to measure the opposite displacement. The accessory  bearing 6 is thereafter placed in the position corresponding to the mean value of both  the displacements and is secured.

Abstract: PURPOSE:To prevent a molded article having a sleeve with an undecut surface from deforming remarkably when the sleeve is pulled out forcibly. CONSTITUTION:A sleeve ejector pin 66 is fixed to ejection plates 57 and 58. Into the sleeve ejector pin 66, an undercut pin 67, which forms an undercut surface, is fitted slidably. The undercut pin 67 is pushed with a spring 71 so as to eject a sleeve 2 together with the sleeve ejector pin 66. After the sleeve 2 is pulled out of a movable retainer plate 46, the undercut pin 67 is stopped by being checked with the stepped face 75 of a movable mounting plate 49. Under the state as mentioned above, the sleeve ejector pin 66 pushes the sleeve out, resulting in getting the sleeve 2 out of the undercut pin 67. Accordingly, since the sleeve ejector pin 66 directly pushes out the sleeve 2 at forcible pulling- out, no burden is applied onto a molded article.
