In order to propose a method of promptly judging movement of a train between block sections with a minimum number of transponders, an on-ground train control part for controlling operation of a train; an on-ground communication means capable of performing communication of information by coming within a specified range; and a sending-and-receiving part capable of sending the information received by the on-ground communication device to the on-ground train control part and receiving the information sent from the on-ground train control part, are provided, thereby, a position of presence of train is grasped by receiving a speed of the train using the on-ground communication means when the on-train communication means attached to the train comes near.
摘要:
The reproduction characteristics, particularly the C/N ratio of a reproduced signal of an optical recording medium are deteriorated by an unevenness or deformation of an optical recording layer due to a convex or concave configuration of underlying guide means that are formed on the surface of the substrate. This deterioration can be prevented by disposing a leveling layer under the recording layer, but the leveling layer lowers the efficiency of the servo tracking. This lowering of servo tracking efficiency is prevented by insertion of a dielectric layer between the leveling layer and the guides.

摘要:
A train control method and apparatus for controlling the movement of trains with high safety by detecting trains on sections of track by an electronic blocking system. A wayside communication element (wayside transponder) 5 is placed in each block section on a track on which a train 1 runs. A cab communication element (cab transponder) 3 which can communicate with the wayside communication elements on the track is placed on the train 1. When receiving a train identifier (ID) from a train, a wayside control device transmits the current position information and the stop position information to the train. The cab communication element of the train 1 receives the current position information and the stop position information, creates a protection speed pattern between the current train position and the stop position from the received information, and limits the speed of the train 1 by the protection speed pattern.
摘要:
A magneto-optical recording medium in which direct overwriting can be done by only modifying the power level and/or the pulse width of applied optical pulses, and without changing the direction of the bias magnetic field. The recording layer comprises first and second magnetic recording layers. The first magnetic layer is a rare-earth transition metal-amorphous alloy and has a perpendicular easy magnetization axis, a thickness of 10 to 200 nm, and a compensation temperature above room temperature. The second magnetic layer comprises an alloy of a first component of Co and/or Fe and a second component of a rare earth metal and/or a noble metal or an alloy of Co and at least one metal selected from Ti, Cr, Mn, Cu, Zn, Ga and Ge. The second magnetic layer is a material having an in-plane easy magnetization axis such that it has a magnetization axis parallel to the second magnetic layer if formed independently on a dielectric layer, the second magnetic layer having a thickness of not more than 3 nm.

A magneto-optical recording medium having an improved durability or reliability is obtained by providing a protecting layer of an alloy of titanium with one or more of chromium, rhenium and tantalum. This titanium alloy protecting layer has an improved resistance to oxygen, water, chlorine, and acids, etc. and provides an improved resistance to the environment and attacks from the synthetic resin substrate or other layers constituting the medium, such as a dielectric layer and a reflecting layer.
