Title: Input buffer circuit
Inventor: ASAI HIDEYASU
IPC: H03K19/017
Filed: 1985-11-15
Abstract: PURPOSE:To reduce the delaying time at an input buffer circuit, by pulling up an output to a power source by utilizing an one-shot pulse which is produced when the input changes from a high level to a low level at the input buffer circuit. CONSTITUTION:When an input changes from a low level to a high level, an one-shot pulse N2 holds a high level, because the output of an input buffer 1 becomes a low level at a moment t1 before the moment when the output N1 of a delay circuit 33 becomes a high level. When the input changes from a high level to a low level, on the other hand, outputs of NAND circuits 34-37 quickly become low levels, because the output of the input buffer 1 changes from a low level to a high level at a moment t3 before the moment t4 when the output N1 of the delay circuit 33 changes from a high level to a low level. In other words, since the output is pulled up by conducting the QP 21 of a pull-up circuit 2 at the moment t3, high-speed pull-up is realized.

Title: Electronic tooth brush
Inventor: MATSUNAGA TADASHI
IPC: A46B15/00
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To stably apply and maintain a constant voltage required for sterilizing plaque on teeth by connecting a working electrode to apply an electric potential to an oral cavity, a counter electrode and a reference electrode to be a setting standard together. SOLUTION: An electric potential applying device 8 is connected to electrodes 5, 6 and 7 by lead wires 45, 46 and 47 through lumens 42, 43 and 44 formed in a brush main body 41. When the electric potential of the working electrode(WE) 7 rises and an excess current flows along the lead wire 47, for example, the voltage of a normal rotation input terminal of an arithmetic amplifier drops due to a voltage drop by a resistance and the output becomes a low level. As a result, the output electric potential falls and the electric current flowing between the counter electrode(CE) 5 and the working electrode(WE) 7 decreases. The decrease in the electric current lasts until the electric potential of the working electrode(WE) 7 becomes a set value, and the voltage drop due to the resistance returns to the original value.  Thus, the electric potential between the input terminals of the arithmetic amplifier, that is, the voltage of the working electrode(WE) 7 is always kept constant. As a result, fluoride ions are effectively led to teeth and the effect of tooth decay prevention can be enhanced.
