摘要： PROBLEM TO BE SOLVED: To provide an alarm light for railroad crossing allowing a lighting fixture to be fixed to a lamp box certainly and having a light emission surface with a uniform hue density. SOLUTION: The alarm light for railroad crossing includes a combination of a lamp box 1, lens 2 and lighting fixture 3, wherein the lighting fixture 3 has a case 4 and LED 5. The case 4 is removably inserted into an opening 21a provided for installation of the case and fixed to the edge of the opening 21a with fastening screws 23. The LED 5 is stored in the case 4 to form light emission surface for displaying and is covered with the lens.

摘要： PROBLEM TO BE SOLVED: To ensure the safety on a main line when set-off equipment is installed on the main line.
SOLUTION: A train protective device for the set-off equipment has a key lock mechanism. The key lock mechanism uses a common key for controlling the protective function of the set-off equipment, starting a monitoring controller, and unlocking the set-off equipment prior to installation the set-off equipment on a main line. The controller is started by handling a start button 19 while the key is inserted in a key switch of the controller, and then, the draw-out of the key from a key hole of the key switch is invalidated during the estimated time in which the train passes the approach prohibition zone set on the main line.

摘要： PROBLEM TO BE SOLVED: To provide a special light signal emitting machine of LED wide diffusion type capable of securing a specified visual confirming distance without increasing the number of installed signal emitting machines even in a curved division. SOLUTION: When this special light signal emitting machine of LED wide diffusion type is to be installed, the angle of the light emission surface is adjusted so that the beam of light Ri at one end to form the diffusion angle of a light emission surface is cast in the tangential direction of a curve C in a position on a straight line D2 of the track going beyond the curve C relative to the advancing direction of a train T running on a straight line D1 toward the curve C while the beam of light Le at the other end intersects the track on the straight line D1 before the curve C in a position at least farther than the visual confirming distance reckoned from the light emission surface.

摘要： PROBLEM TO BE SOLVED: To confirm visibility of an object railroad signal from a plurality of adjacent railroad signals and its other noise component. SOLUTION: When the (i)th and the (i+1)th flashing patterns are the same, a determination is made on whether or not an absolute value of a difference between luminance Aj+1 of a picture element of the (j+1)th image and luminance Aj of a picture element of the (j)th image exceeds a threshold value Th, and when the absolute value does not exceeds the threshold value Th, a value is set to 1, and when exceeding the threshold value, the value is set to 0, and extraction processing is performed for extracting an area (207). When the (i)th and the (i+1)th flashing patterns are different, a determination is made on whether or not the absolute value of the difference between the luminance Aj+1 of the picture element of the (j+1)th image and the luminance Aj of the picture element of the (j)th image exceeds the threshold value Th, and when the absolute value exceeds the threshold value Th, the value is set to 1, and when the absolute value does not exceeds the threshold value, the value is set to 0, and processing is performed for extracting the area (208). When the binarizing processing is formed in a frame of the whole N bits, a collective operation of an extraction area equivalent to the N bits is performed (211), and the visibility of the railroad signal is confirmed by its result (212).

摘要： PROBLEM TO BE SOLVED: To simplify work for exchanging a cylinder body of special signal emitting equipment. SOLUTION: The special signal emitting equipment comprises a detachable combination of the cylinder body 1, an emitter 2, a cover 3, a cap 4 and a holder 5. The cylinder body 1 of a transparent synthetic resin has a dowel engaged with a cutout and positioned by a holder 5 and is supported in a detachable manner. The emitter 2 has a board 8 and a LED 9 to form an emitting plane 11. The cover 3 covers the upper end of the cylinder body 1 and is detachably joined to the board 8 with a screw, and the screw joining the cover 3 to the board 8 is held by the cover 3 while being prevented from falling. The cap 4 in a conical shape is screwed into the cover 3 and mounted at the upper end of the cylinder body 1. The holder 5 is mounted on a support column 14. COPYRIGHT: (C)2003,JPO
