Abstract: This invention relates to a continuous perfusion apparatus of a liquid for use in cell culture, hydroponics, breeding, and the like. The perfusion apparatus comprises (1) a container which is horizontally partitioned by an inner lid and whose upper part is open, (2) a hollow cylinder (A) and a small pipe (B) which penetrate through the inner lid to effect communication of the spaces above and below the inner lid with each other and (3) a blast pipe (C) for feeding air into a space below the inner lid. One of the ends of the hollow cylinder (A) is positioned above (a) the inner lid while the other end near (b) the bottom wall of the container. One of the ends of the small pipe (B) is positioned above (c) the inner lid while the other end immediately below (e) the inner lid. Its central part extends downward and is bent by 180 DEG  near the bottom wall of the container, but its lowermost part (d) is on a level a little above the lowermost end (b) of the hollow cylinder. After a liquid is fed into the container, air is blown into the space below the inner lid so as to lower an artificial water surface inside this space. When the artificial water surface reaches the lowermost part (d) of the small pipe, the air filled in the space below the inner lid escapes to the upper part of the inner lid through the small pipe (B) and the artificial water surface rises. When this surface reaches one (e) of the ends of the small pipe, lowering of the artificial water surface again takes place. In this manner, the artificial water surface moves up and down repeatedly to cause perfusion of the liquid in the container.

Abstract: An X-ray tube anticathode, intended to be used, for example, in medical instruments, such as scanners, includes a support made of a ceramic/ceramic composite material and a refractory metal film directly in contact with this support. The use of a ceramic/ceramic composite makes it possible to rotate the anticathode at an extremely high speed. In addition, this composite is selected 1) so that its coefficient of expansion is as compatible as possible with that of the refractory metal, which favors adhesion between the support and the active film, and 2) so that the phenomenon of the diffusion of carbon atoms is suppressed or minimized at the active film under the effect of the rise of temperature by not using a graphite material, which renders it ineffective in using an anticarbonizing film, such as rhenium, indium, SiC, etc.

Abstract: A fused, redundancy selection circuit (20) is disclosed which is disabled by the absence of a chip select signal (CS). The circuit has the feature of avoiding the use of nodes with a floating potential and in this manner it provides an enhanced radiation hardened characteristics. The circuit is effectively disabled if no redundancy is required on a particular memory chip, by leaving fuses which are a part of the circuit, intact. Alternately, if the memory chip is tested to have defects, the redundancy circuit (20) is selectively enabled to provide the desired redundancy for the chip, by blowing fuses which are a part of the circuit. Thereafter, the redundancy circuit is now an active part of the memory chip and it is selectively enabled when the chip select signal (CS) is applied to the chip. An advantageous feature of the circuit is that it does not dissipate power when its function is not required either because its enabling fuses have not been blown or alternately when the chip select signal is off. In this manner, a zero standby power, radiation hardened memory redundancy circuit has been provided.

Abstract: This invention relates to barrier seal systems (10) for sealing the annular space between a housing (14) and a rotating shaft (12) which extends through a bore (16) in the housing (14). The seal system (10) has inboard (66) and outboard (46) mechanical end face seals. The inboard seal (66) faces have spiral grooves (98) for pumping a buffer fluid from a buffer chamber (68) between the two seals (46-66) toward the high pressure side of the inboard seal (66). The primary ring (76) of the inboard seal (66) may be double balanced. For high pressure applications, the buffer fluid may be pressurized and a pumping ring may be included in the outboard seal to circulate buffer fluid. High pressure applications also require two hard seal rings and optimum dam (100) and face widths. Buffer fluid can be supplied to the seal system by a reservoir (30) connected by a gravity feed line (108-112). A buffer fluid containment device may be attached to the high pressure side of the seal (10) to prevent process fluid from contaminating the seal faces or secondary seals.
