Title: Frame synchronization protection circuit
Inventor: IKUMA HIROSHI
IPC: H04L7/08
Filed: 1987-03-20
Abstract: PURPOSE:To attain backward protection by a count of counters of the number of stages equal to the backward protection stage number by inputting a detection output of a frame pattern detection circuit to a reset terminal not only to a set terminal of an SR flip-flop of an alarm control circuit. CONSTITUTION:If a frame pattern detection circuit 1 does not detect a frame pattern synchronously with a 1st decoding signal H1 but detects at the next point of time at the point of time of the first frame pattern detection after the occurrence of alarm, an output D of an alarm control circuit 3 goes to 1 and an output C of the reset signal generator resets it to zero. During this time, the clock CLK of the frame counter 7 is not inhibited and 0 is fetched in the alarm counter 4. In detecting the frame pattern by the pattern detection circuit 1 in synchronism with 0 of the 1st decoding signal H1 at the point of time of the detection of next pattern, the alarm counter 4 fetches and counts 1 being the conversion of output D to apply normal operation.

Title: Fire alarm equipment
Inventor: MIYASHITA HIROMI
IPC: G08B17/00
Filed: 1993-03-25
Abstract: PURPOSE:To enable a person to refuge to recognize the relative position with a point where a fire broke out by preparing the display devices at the necessary parts of a building to show the break-out of fires, etc., and also the relative fire break-out positions around each display device itself. CONSTITUTION:When a fire sensor 233 detects a fire, the sensor 233 transmits its address and a fire signal to a fire signal receiver 4 based on a polling. Thus the receiver 4 recognizes that a fire broke out at the position of the sensor 233 from the received address. Then the receiver R produces an alarm and shows it at its own display part. Then the fire display instructions are sent to the display devices 511-543 via the repeaters 31-34. The display device 541, for example, recognizes that the sensor 233 produced an alarm the address added to the received fire display instruction. Thus the sensor 233 shows the break-out of the fire and at the same time decides the position of the sensor 233 around the device 541 to show that a fire broke out at the opposite side of a first floor for instance.

Abstract: PURPOSE: To allow a train to travel with minimum necessary electric power by outputting an idle control signal when the traveling speed of the train becomes faster than a notch-off speed responsive to the traveling time to its destination.  
     CONSTITUTION: An instruction signal T relative to the traveling time to next station from an operation command is located to a memory 9, and a traveling time vs. notch-off speed table 3 outputs a notch-off speed 3a responsive to the value of the memory 9. When the traveling speed 2a of the train is slower than the notch-off speed 3a, a comparator 4 produces a compared output to close a power drive relay  5 ON. Thus, a power drive command is applied to a train controller 10. When the traveling speed 2a becomes faster than the notch-off speed 3a, a power-OFF relay 7 is energized to allow an idle command to the controller 10. When the idle command is thus outputted, the table 3 will advance to a table for next station.
