Title: Signal monitor method
Inventor: SUZUKI EIJI
IPC: H04L1/20
Filed: 1984-07-28
Abstract: PURPOSE:To simplify the constitution of a monitor circuit by deciding a signal fault in a case that a state where ''1'' or ''0'' is delivered at a time from all signal lines is not detected for a fixed period or longer. CONSTITUTION:An AND circuit 1 secures the AND of data lines D1-D4; while an AND circuit 3 secures the AND of the output of an inverter. A 1-shot multi- vibrator MV detects the fall 7 of the output (a) of the circuit 1 and tries to deliver ''0'' for the fixed period T. However this output is kept ''0'' if another fall 8 is produced again during the period T. In the same way, the output of an MV5 is also set at ''0'' in a state where lines D1-D4 deliver all ''0''. As a result, the output (d) of the MV5 is set at ''1'' when the period T passes from a fall 11 produced immediately before the generation of a fault in a case that the output of a certain data line is set continuously at ''1''. Then the output (e) of an OR circuit 6 is also set at ''1''. A case where the output of a certain data line is continuously set at ''0'' is also in the same way.

Title: Relay drive device
Inventor: OBARA SHINICHI
IPC: H01H47/32
Filed: 1987-06-25
Abstract: PURPOSE: To design the reduction of a drive current by providing a 2nd drive for applying the drive current by means of a pulse output from a pulse generating means to a reset coil of a double winding latch-in relay.  
     CONSTITUTION: A Schmitt circuit 2 works to change an output V 3  from 'L' to 'H'. The output is then converter to a pulse of a sufficient width to drive a double winding latch-in relay connected, by means of a pulse generating circuit 3 according to the buildup of the output V 3 . The converted output V 4  is then power-amplified with a drive circuit 4 and a drive current is applied to a setting coil Ws to drive the double winding latch-in relay. If a drive power source voltage V 1  then gradually lowers and reaches a reset voltage, an output of a voltage dividing circuit 5 changes to 'L.' Since the output V 3  of the Schmitt circuit 2 at this time still remains at 'H,' an output V 5  of a gate circuit 7 becomes 'H,' which is amplified with a drive circuit 8 so that a drive current is applied to a reset coil Wr to reset the double winding latch-in relay. This makes it possible to reduce current consumption and to operate in a wide range of drive power source voltages.
