摘要： PROBLEM TO BE SOLVED: To make it possible to reliably judge and detect the rise and folded state of a current collector by using only two air pipe insulators. SOLUTION: A mechanical valve 36 is arranged for detecting the folded state in a high pressure air circuit supplied through air pipe 35 → air pipe insulator 23 from a pressure source, also a mechanical valve 37 for rise detection is arranged in a low pressure air circuit supplied through air pipe 35 → air pipe insulator 23 → pressure reducing valve 38. When the current collector is in rise state, the mechanical valve 37 is switched and the passage is turned into a low pressure state. Because of this, a pressure switch 39 is turned on, pressure switch 40 is turned off, and the rise of the current collector can be judged and detected by a logic element 41. Also, when the current, collector is folded, the mechanical valve 36 is switched and the passage is turned into a high pressure state. Because of this, the pressure switch 39 and 40 are turned on, and the folded state can be judged and detected by a logic element 42.

摘要： PURPOSE: To make it easy to draw out a sandwiched object by energizing a solenoid switching valve for weakening a door closing force, and weakening the door closing force through the weakening of the closing pressure of an air cylinder. CONSTITUTION: A three-port solenoid valve 8 serving as a solenoid switching valve for weakening a door closing force is placed between the air supply port 1b1 of a valve element 1b located on the door closing side of an air pressure cylinder 1 and a four-port solenoid valve 6 serving as a solenoid switching valve communicated with an air pressure source 7. A relief valve 9 is connected to the exhaust side 8a of the three-port solenoid valve 8. Before a train starts, the doors 5a, 5b are closed on command from the conductor, during which the door closing force is weakened by temporary control of the solenoid switching valve for weakening the door closing force, or when a detector detects that some object is sandwiched between the doors, the force to close the doors 5a, 5b is weakened by energizing the detection signal by means of the three-port solenoid valve 8 serving as the solenoid switching valve for weakening the door closing force, and releasing pressure not less than the set pressure of the relief valve 9.

摘要： PURPOSE:To accurately measure the slider wear amount of a pantograph and the deformed amount of a shoe without contact by a relatively small-sized sensor. CONSTITUTION:A one-dimensional image sensor 9 is installed oppositely to the longitudinal direction of the slider of a pantograph 4 at the front and/or the rear of the advancing direction of a moving electric railcar 1 to image the slider or the shoe of the pantograph 4. As the railcar l moves, the sensor 9 sequentially detects the one-dimensional image information of the slider or the shoe, and fetches the information in synchronization with the vehicle speed or at each vehicle or composition. Thus, a secondary image of the slider or the shoe is obtained at each vehicle or composition. A measuring system 10 processes the obtained image to obtain the wear amount of the slider or the deformed amount of the shoe, and to generate an alarm signal when the wear amount or the deformed amount exhibits an abnormal value.

摘要： PROBLEM TO BE SOLVED: To easily make an electric rolling stock airless, eliminate an air wiring inside the rolling stock and at the same time reduce the sound of a compressor by operating a pantograph as an electrically-driven type using a linear motor. SOLUTION: A motor 19a is used as a power source, and a horizontally moving shaft 19c is moved left and right on the paper through reduction gears 19b. A freely turnable coupling part (b) is provided at its one end, and a mechanism into which an insulating material 20 and a long-hole link 16 are integrated is adopted as an operating device. In the constitution, a main shaft 13 is made to pass through the long-hole link 16 and a pin 15 at the tip of a fixedly connected lever 6 is made to pass through the long-hole link 16. With the rise of a pantograph, a horizontally moving shaft 19c is moved in the right direction by the rotation of the motor 19a through the reduction gears 19b, and the pantograph is made to rise along a moving quantity with the power of a main spring. On the other hand, at its descent, the horizontally moving shaft 19c is moved in the left direction by reversing the rotation of the motor 19a to pull the lever 6 against the main spring, so that the pantograph is descended to bring it into the state of being folded.

摘要： PROBLEM TO BE SOLVED: To solve the problem with a rolling stock door that the response of a door closing force to control is delayed as the amount of air, i.e., the capacity of a compressor, increases, caused by the fact that a door closing force of 50 to 60 kgf is normally obtained by application of an air pressure of 5 kgf/cm2 to the door closing side valve element of a door closing air cylinder and that weakening the door closing force requires application of an air pressure of 1.5 kgf/cm2 to the door closing side valve element to hold a door opening side valve element at the atmospheric pressure, in which case reducing the pressure from 5 kgf/cm2 to 1.5 kgf/cm2 requires approximately 70% of the amount of air to be discharged while raising the pressure again to its initial value requires approximately 70% of the amount of air to be confined. SOLUTION: A normal air pressure of 5 kgf/cm2 is applied to the door closing side valve element and an air pressure of 3.5 kgf/cm2 is applied to the door opening side valve element to obtain a door closing force of approximately 18 kgf.
