Patent JP-S62253210-A (JP)
Title: Schmitt trigger circuit
Inventor: KANAMORI KIMINORI
IPC: H03K3/353
Filed: 1986-04-25
Abstract: PURPOSE:To eliminate the disabled operation due to the variance in manufacture by inserting a resistor between drains of a PMOS and an NMOS forming an inverter connected to an input terminal so as to set the hysteresis width to a remarkably wide range. CONSTITUTION:When a level of a input terminal 17 is a potential Vss, the level of a connecting point 18 is VDD, the level of an output terminal 19 is Vss, PMOS transistors (TRs) 11, 13 are turned on and NMOS TRs 15, 16 are turned off. In increasing the potential at the terminal 17 and when it reaches a potential VT of the TR 15, the TR 15 is turned on to decrease the potential at the point 18. In increasing the potential furthermore, the potential at the point 18 is decreased more, and when the potential reaches a threshold voltage of an inverter 20, the potential at the terminal 19 changes from the Vss to the VDD, the TR 13 is turned off, the TR 16 is turned on to accelerate the inversion. Suppose that the conductance gm of the TR 15 is far smaller than the others, the potential at the point 18 does not quickly rise. In increasing, however, the potential at the terminal 17 to VDD-¦VTP(VT of PMOS)¦, the TR 11 is turned off, the potential at the point 18 is lowered and inverted without fail. Then the maximum value of the hysteresis width VH is VH=VDD-(VT of NMOS +¦VTP¦).

Abstract: PURPOSE:To improve the low temperature characteristics and heavy load characteristics of an alkaline battery by adding a water soluble compound having alkyl group containing phosphoric acid in an electrolyte or in a negative electrode. CONSTITUTION:A positive compound mold 2 is compacted in a metallic outer container 1 which serves also as a positive terminal. A nonwoven fabric 4 is placed on a separator 3, and a gel zinc negative electrode 5 of the alkaline electrolyte is placed on it. An insulating packing 7 is engaged to a sealing plate 6 which serves also as a negative terminal, an opening 8 of the container 1 is folded inwardly to fasten, and a button-type alkaline battery is constituted. The negative electrode 5 is formed by adding a chemical compound having phosphoric acid containing alkyl group, glue, and zinc powder in the electrolyte to form a gel. The negative electrode 5 may be formed by adding and mixing said chemical compound after the negative electrode is formed. This compound masks zinc ions which is generated through the discharge reaction of zinc, disperses in the electrolyte, and prevents the formation of passive state of the negative electrode.
