Title: Data transmission system for key telephone system
Inventor: SUGANO KENICHI
IPC: H04Q3/58
Filed: 1986-04-07
Abstract: PURPOSE:To allow a pulse signal with polarity to correctly decode data regardless of the polarity of connecting a signal line through a pair of lines in terms of a key telephone set by detecting a change in a logical value, which is made by the bit of a specific logical value and further detecting the polarity that the bit of a reverse logical value shows in accordance with the former detection. CONSTITUTION:A start signal Ss inclduing a positive bit B1 as the bit of a specific logical value and negative bits B2 and B3 as the bits linked to said positive bit up to the prescribed order is returned. In an ST2 the change in the logical value due to the bit B 1 is detected by a change in a voltage in a negative direction. The poliarty shown by the bit B3 at a point t2 where 1.5 bits pass at a detection point t1 is detected. If it is negative, the connection polarity of the signal line 3 is judged to be regulated polarity. Whereas it is positive, the connection polarity is judged to be reverse. According to the judged result, the positive or negative logic of a transmission signal is selected.

IPC: H01L21/822
Filed: 1995-03-10
Abstract: PURPOSE: To provide an integrated circuit which saves the area and power of an integrated circuit by constituting a specific circuitry using MOS transistors. CONSTITUTION: When a power source voltage VCC is impressed on the drains of n-type MOS transistors N11 and 13, the N11 and p-type and n-type transistors P11, N12 become conductive and operate in the saturated region so that the potential of the internal node (a) becomes below the difference between VCC and the threshold voltage VTH of the MOS transistor. The potential of the internal node (b) is less than VCC-2VTH and higher than VTH. The voltages of these internal nodes (a), (b) are impressed on the gates of N13 and a p-type MOS transistor P12 to make N13 and P12 conductive. Hence, the voltage obtained by proportionally dividing VCC between N13 and P12 is generated at the output node OUT. This time, by equalizing the characteristics of N11 and N13 to those of P11 and P12 respectively, the voltage equal to half of VCC is stably supplied.  Like this, the circuit composed from 5 transistors system realizes area saving and power saving.
