IPC: G05B11/26
Filed: 1978-07-21
Abstract: PURPOSE:To obtain a high-reliability fault diagnostic unit of simple constitution by sending out at constant interval of time a fault diagnostic false signal with pulse width small enough for an electromagnetic actuator not to respond. CONSTITUTION:Each wheel speed signal Uw1, input signal to inlet valve 14 and output valve 19 of electromagnetic actuator Sin-1 and Sout-i of each wheel, is inputted to input signal modulator 23-1 by a fault diagnostic false signal (a) with  pulse width small enough for an actuator not to answer and after modulation, the  output signal is inputted to control circuit 24. Each control logic circuit 26-1 of circuit 24 receives reference wheel speed signal UR from reference wheel speed setter  25 and signal Uw1 and then sends the result of logical operation to the actuator,  thereby operation signals (b1) and (c1) of valves 14 and 19. If some abnormality is  found in signals (b1) and (c1), fault diagnostic unit 27 generates signal (m) indicating the fault to let alarm generator 31 know and the power supply to the control circuit is cut off. Consequently, the fault can be diagnosed without providing a signal  cut-off unit and switching unit.

Inventor: ITO FUMIO
IPC: H03H11/12
Filed: 1989-04-07
Abstract: PURPOSE:To keep an amplitude level constant even when a pole frequency is changed by providing a Q control circuit which controls the feedback quantity of a feedback circuit network. CONSTITUTION:The feedback circuit network 7 is inserted between an output terminal 6 and the (1) input terminal of a transconductance amplifier 2a, and the Q control circuit 8 changes the Q value of a low-pass filter by controlling the on and off of the switch 71 of the feedback circuit network 7. In other words, the feedback quantity of the feedback circuit network 7 is controlled so that the Q valves in a calculation value at a low pole frequency can be set higher than that at a high pole frequency by the Q control circuit 8 when the pole frequency is decreased, and adversely, the Q valves can be suppressed when it is increased from the low pole frequency to the high pole frequency. In such a way, the amplitude level can be controlled at a decided amplitude level when the pole frequency of a filter is decreased or increased.

IPC: H04B1/709
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To eliminate influence of noise in detection for a train by inputting a signal from a terminal side of a rail constituting a track circuit and detecting existence of a train on a rail on the basis of the corresponding condition with a predetermined code detected by using a predetermined coefficient. SOLUTION: After a carrier wave (fc) is diffused in a diffusion circuit 11 in a transmitter (a) in a track circuit T1 by using a PN code (PN1 (θ1 )) allocated to the track circuit T1 , the carrier wave (fc) is fed out to the starring end side of the track circuit T1 via a transmission circuit 12. Using a relative value, which is found in a relative apparatus 24 by using a coefficient outputted from a coefficient generator 30, a CPU 25 outputs determination of existence of a train because no PN code (PN1 (θ1 )) from the transmitter (a) is detected while the track circuit T1 is short-circuited by an axle of the train, on the other hand, determination of no train is outputted when the PN code (PN1 (θ1 )) is detected.  In this process, a PN code (PN2 ) is used as a coefficient for the relative apparatus 24, so that the relative value can be detected without any influence of noise.

Filed: 1980-06-30
Abstract: PURPOSE:To enable to discriminate both odd and even number of fields stably with good accuracy, by starting the count from the specified time point of a vertical synchronizing signal, resetting it with a relating horizontal synchronizing signal and transmitting the level from high to low level after it reaches a specified amount. CONSTITUTION:For example, in an odd number of field as shown in Figure, an input CU of a counter 12 supplies the result of logical product between a signal V8 having 1H or more pulse width and the reference signal CP in frequency (1/50H)Hz for count, and on the other hand, the horizontal synchronizing pulse H14 is applied to the R of the counter 12 for periodical reset, and the result is applied to A of a comparator 15. The reference value is applied to another B, and if A>B, AH is at ''1''. Thus, the AH pulse is produced at 5H after the vertical synchronizing signal V starts and it is inputted to D of a latch circuit 20. Further, V19 is applied to the input T and the OF is at high level at an odd number field. On the other hand, at an even field, after the vertical synchronizing signal is started, output is made at 4.5H and the OF is at low level. Thus, the discrimination of both the fields can be made stably, without temperature change and noise.
