Title: Associative memory cell circuit
Inventor: NAGAI HAJIME
IPC: H01L27/10
Filed: 1986-05-16
Abstract: PURPOSE:To reduce the number of circuit elements, and to perform integration with high density, by making a flip-flop by accumulating data complementarily in two capacitors, and constituting the memory cell circuit of associative memory of two memory circuits of dynamic RAMs, and a comparison circuit. CONSTITUTION:The write and the read of the data is performed through bit lines Bj, and the inverse of Bj, by driving a word line W1 selectively, and energizing the first transistor 1, and the second transistor 2. The data are accumulated in the second capacitor 7, and the first capacitor 6 respectively in the form of accumulation of electric charge. It is necessary to rewrite accumulated charge periodically to prevent from being dissipated, but, a rewrite can be realized by the same method as in the ordinary refresh operation of the dynamic RAM. In a comparison operation, the word line W1 is not operated, and the data to be compared are put on the bit lines Bj and the inverse of Bj, and they are compared with the data stored in the first and the second capacitor 6 and 7. When the data coincide, the gate of the fifth transistor 5 is driven to go to an off (low level) state.

Title: Apparatus for producing water containing potassium ion
Inventor: HIRABAYASHI TERUYUKI
IPC: C02F1/42
Filed: 1988-05-12
Abstract: PURPOSE:To produce soft water having no increased concn. of Na ion by introducing feed water from a feed water introducing pipe, passing the feed water through a layer packed with a K type cation exchange resin, and obtd. treated water wherein hardness components in the feed water have been exchanged with K ions. CONSTITUTION:Feed water is introduced through a feed water introducing pipe 3 into a vessel 1, and passes through a packed layer of a K type cation exchange resin 2. During the passage of the feed water, hardness components in the feed water such as Ca ions, Mg ions, etc., are ion-exchanged with K ions. Such ion-exchanged treated water is discharged from a treated water discharge pipe 4. The Na ion content of the treated water is considerably small as compared to the Na ion content of conventional soft water, and K ion content is increased on the other hand. When the Ca ion content of the cation exchange resin 2 approaches a saturation point in a water passing stage, hardness components begin to leak in the treated water. Accordingly, a regeneration stage is started at this stage.
