The Central Japan Railway Company is the main railway company operating in the Chūbu region of central Japan. It is officially abbreviated in English as JR Central and in Japanese as JR Tōkai . Its headquarters are located in the JR Central Towers in Nakamura-ku, Nagoya, Aichi Prefecture.The company's operational hub is Nagoya Station. The busiest railway line it operates is the Tōkaidō Main Line between Atami Station and Maibara Station. JR Central also operates the Tōkaidō Shinkansen between Tokyo Station and Shin-Ōsaka Station. Additionally it is responsible for the Chūō Shinkansen—a proposed Maglev service between Tokyo Station and Ōsaka Station , of which a short demonstration section has been built. Currently, the company is conducting demonstrations of its shinkansen to railway officials from different countries in the effort to market bullet train technology overseas.JR Central is Japan's most profitable and highest throughput high-speed-rail operator, carrying 138 million high-speed-rail passengers in 2009, considerably more than the world's largest airline. Japan recorded a total of 289 million high-speed-rail passengers in 2009. Wikipedia.

An electric power receiving device in one aspect of embodiments of the present disclosure comprises an electric power receiving section and a converting section. The converting section comprises a compensation voltage generating section. The compensation voltage generating section generates a compensation voltage capable of canceling out a reactance component in the electric power receiving section, and applies the compensation voltage to the electric power receiving section. The compensation voltage generating section comprises a phase changing section, a physical quantity detecting section, and a searching section. The searching section searches a target phase of the compensation voltage that brings the electric power receiving device into a substantially resonant state, based on a physical quantity detected by the physical quantity detecting section. The compensation voltage generating section determines the compensation voltage having the target phase as the compensation voltage to be applied to the electric power receiving section.

A damage detecting device according to one aspect of the present invention comprises a first speed generator, a second speed generator, a first waveform shaping section, a second waveform shaping section, and a determining section. The determining section compares a second rectangular wave shaped by the second waveform shaping section and a first rectangular wave shaped by the first waveform shaping section and, if the first rectangular wave is not output while the second rectangular wave is output, determines that a supporting device for an armature shaft is damaged or worn.

In a power supply device, the bridge circuit is configured by connecting, in parallel, a plurality of series circuits of an inverse-parallel connection circuit of a semiconductor switch and a diode. A control unit controls switching of a semiconductor switch so that a voltage v between AC terminals becomes zero voltage in equal periods before and after a center point shifted from one zero crossing point in one cycle of the input current by a compensation period (angle) calculated from a voltage applied to a resonance circuit constituted by the power receiving coil and a resonance capacitor C

In brake control based on commands of a plurality of systems, an adjustment valve adjusts fluid supplied from a fluid source to a predetermined pressure to output the pressure-adjusted fluid. An output valve switches opening and closing based on a switching command. A skid detector detects whether a car is skidding or not and notifies a brake controller. The brake controller determines a pressure of fluid output by a control valve and issues a command to solenoid valves provided in the control valve. The brake controller issues a command to a discharge valve to discharge fluid from the discharge valve when a skid is detected. A relay valve adjusts pressure of fluid from the fluid source based on a higher pressure between a pressure of fluid output by the output valve and a pressure of fluid output by the control valve, to output the pressure-adjusted air to a brake cylinder.
