Title: Train speed level detector
Inventor: YAMAMURA MASAYORI
IPC: B60L3/08
Filed: 1979-09-21
Abstract: PURPOSE: To simplify this device, and to reduce cost, by decreasing the locations of frequency comparators by mounting a means, which compares the second frequency among three frequency signals and speed frequency signals, and a means, which changes over the second frequency to the first and third frequency according to any of the output and compares them.  
     CONSTITUTION: When the speed Vx of a train is not less than H=5km/h, the output of a comparator 1 is in ON, the output is input to an AND circuit 4 and a pattern Ix is put out. In this case, the output is also input to an inverter 3, and disconnection detecting frequency G for obtaining the output of OFF is not put out. The pattern output Ix of the AND circuit 4 and the train speed Vx are compared by means of a comparator 2, and the output is in ON when the pattern is larger. When the exclusive-or of the output of the comparator 2 and the output of the comparator 1 is calculated, the output of an OR circuit 6 is in OFF, and a brake is in OFF at that time. Thus, the levels of train speed frequency can be detected by using two frequency comparators.

IPC: G02F3/00
Filed: 1984-06-12
Abstract: PURPOSE:To form an optical exclusive-OR circuit on one substrate by the constitution in which the phase speed of the light propagating in the two branch optical waveguides constituting a Mach-Zehnder type optical waveguide is controlled by the other input light signal. CONSTITUTION:The output light signal Iout is absent of light when the input light signals IinA and IinB are both absent of light. The signal IinA is equally branched to the two branch optical waveguide parts 51, 52 in the Mach-Zehnder type optical waveguide 50 and is propagated therein when the signal IinA has light and the signal IinB is absent of light. The signal Iout having the power approximately equal to the power of the signal IinA is obtd. therein. Electromotive force is generated from both photovoltaic elements 21, 22 and the voltage is impressed to electrodes 31, 32 when the signals IinA and IinB are both 1. The signals IinA and IinB are superposed in a Y-shaped waveguide part 13 and the superposed signal is thereafter branched to the parts 51, 52 in the waveguide 50. The electrodes 31, 32 are both impressed with the voltage and therefore the phase speeds of the two beams of the light are equal. The phase difference is therefore n(odd)pi and the signal Iout is 0.

Filed: 1988-05-17
Abstract: PURPOSE:To cut overshoot appropriately in any accelerating condition by correcting the fundamental limitation value of the air amount according to the calculated amount of suction air, and thereupon determining the max. limitation value of the output of an air sensing means. CONSTITUTION:A control unit 20 calculates the suction air amount of an engine from the degree of opening of a throttle valve 8 and the number of engine revolutions and computes the fundamental limitation value of the suction air amount on the basis of the number of engine revolutions. The max. limitation value for the air amount is calculated upon correcting the fundamental limitation value according to the calculated suction air amount. Further the output of an air flow meter 7 is so limited as not exceeding the max. limitation value of the air amount. This allows cutting of eventual overshooting properly in any accelerating condition, which enhances the sensing accuracy of the suction air amount.
