摘要： PROBLEM TO BE SOLVED: To reduce an adverse effect of tentative unsuccessful train sensing at an alarm cease point even when train sensing is performed at the alarm cease point BDC or DDC, at which a train sensing zone Kb or Kd encompasses a railroad crossing, on the assumption of a short circuit between a wheel and rail.SOLUTION: A first sensing point (expansion point BBDC or DDDC) is set between a start point ADC or CDC and a railroad cross, and a cease point BDC or DDC (second sensing point) is set on the railroad cross. When the facts are verified that entry of a train into the start point, entry of the train into the first sensing point, entry of the train into the second sensing point, and exit of the train from the second sensing point have been sequentially performed and that the train has exited from the first sensing point, a decision is made that the train has passed through a railroad crossing 11. After a time of a predetermined alarm delay time element Tc has elapsed, an alarm is stopped. A result of expanded train sensing over a period from the entry of the train into the first sensing point and the exit of the train from the first sensing point and second sensing point is provided as a mask condition for a railroad crossing obstacle sensing unit 29. Switching circuits 51 and 52 are included to allow one of cease point railroad crossing controllers 22 and 24 to perform train sensing relevant to the first sensing point and second sensing point in a time-sharing manner.

摘要： PROBLEM TO BE SOLVED: To realize an LED signal lamp and a railway signal that can be used under the same voltage without performing resistor switching even under a series connection of two lamps and a single lamp. SOLUTION: This LED signal lamp 50 comprises a fitting or disengaging unit having a fitting 21 replaced in a railway signal lamp and a connecting contact portion 22; an LED unit having a plurality of LEDs 52a and 52b connected in such a way that they can be driven concurrently; a rectifier circuit 31 inserted at an electrical power path extending from the connecting contact portion 22 to the LED; and current control circuits 51a and 51b for restricting the current in the electrical power path to an allowable range of the LEDs. In addition to LEDs, the current control circuit is also divided into two groups, and a series connection/parallel connection changing-over circuit 56 capable of changing-over whether or not the two groups are set in a series-connected state or a parallel-connected state is installed. When this is installed at a railway signal unit, the two groups are switched into a parallel-connected state in the series connected two lamps and the two groups of one lamp are switched to a series connection. With such an arrangement as above, all the light emitting signal lamps are lit and driven at a rated voltage. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To change a bulb from a filament bulb to an LED signal bulb while a lamp and a color lens are provided to a color lamp signal.
SOLUTION: A bump 12b is formed on a heat-conductive supporting member 12 insulated from lead members 13, 14, and a blue light emitting diode chip 11 is accommodated in the bump, and covered by a first resin part 17 and a second resin part 15. At that time, a yellow wavelength converting material and a red wavelength converting material are mixed in the resin part 17, and an exposed end 12a is exposed. A supporting member is released from electric supply, and plays only a supporting function and a heat-conducting function, so as to loosen restraints of a heat-dissipation means. Therefore, problems of compatibility in addition to small size, multi-color, and raise in luminous intensity can be solved. Also, a bonding wire 16 is protected by a third flexible resin part 18, and mixed with a wavelength converting material.

摘要： PROBLEM TO BE SOLVED: To provide a voltage setting device for realizing shortening of regulating time of driving supply voltage of a signal installed at a remote place and reduction of the number of working persons, and its setting method.
SOLUTION: A signal light transformer 2 on a power supply side and the signal 4 installed at the remote place are connected by a cable 5. The signal light transformer 2 and the cable 5 are connected to input parts 8 and 8' of this voltage setting device 3 and output parts 9 and 9' of the device 3, respectively. A variable resistor 24 and an AC ammeter 23 are connected in series between the input part 8 and the output part 9. A voltmeter 22 for measuring voltage between the output parts 9 and 9' is connected. By considering voltage drop by resistance of the cable 5, voltage for driving the signal 4 is supplied from the signal light transformer 2. A resistance value of the variable resistor 24 is gradually increased and a display voltage value of the voltmeter 22 is gradually reduced. When a display current value of the AC ammeter 23 is reduced to less than a rated current value, the voltage value by which the signal 4 can not be driven is measured, and a tap of the signal light transformer 2 close to the voltage value is selected.

摘要： PROBLEM TO BE SOLVED: To improve performance and function for substituting a filament type bulb. SOLUTION: This LED signal bulb is provided with an attaching and detaching part 10 having a base 12 interchangeable with a railway signal lamp and a connecting contact part 11, an LED light emitting part 70 having plural LEDs 71, 72, and a rectifying circuit 30 interposed in a power feeding path extending from the connecting contact part 11 to the light emitting part 70. This bulb is provided with a smoothing circuit 40 interposed between the rectifying circuit 30 and the light emitting part 70, a driving circuit 50 for detecting the supply current to the light emitting part 70 and controlling the same constant, a detecting means 60 for detecting the existence/absence of the supply current, and a current application amount switching means 20 for switching the current application amount of the connecting contact part 11 between a large value and a small value according the above detection result. The LED 72 is reverse to the LED 71. Thus, even if the input power supply voltage varies, the light intensity is kept constant so that it can be applied to a signal in which when two lamps are used in series, and one is extinguished due to disconnection trouble, the other lamp is also extinguished to need back light.
