An inverter includes a plurality of switching elements that convert between DC and AC power. A base plate includes a surface on which the switching elements are placed. Heat dissipating fins are provided on the opposite side of the base plate. Power is input and output through AC power terminals to and from a rotary electric machine to drive a vehicle. The terminals are electrically connected to the switching elements. A capacitor smoothes the DC power. The inverter is fixed to a case of the rotary electric machine. A rotating shaft of the rotary electric machine extends in a width direction of the vehicle. The base plate is disposed adjacent to the AC terminals in the width direction. A plurality of AC phase-terminals is sequentially arrayed perpendicular to the rotating shaft. The capacitor is disposed adjacent to the heat dissipating fins on the rear side of the vehicle.

An integrated transmission apparatus includes a plurality of optical supervisory channel (OSC) processing units for processing OSC signals contained in a wavelength division multiplexing (WDM) signal received from a WDM network and a switching unit for performing the path control of synchronous digital hierarchy (SDH) frames. An OSC processing unit transmits the SDH frame, containing wavelength information indicated by, to the switching unit. Another OSC processing unit acquires the SDH frame, containing wavelength information, from the switching unit and sets an OSC signal which is to be appended to the WDM signal to be transmitted, based on the wavelength information.

A gas separation membrane is provided which has both excellent gas permeability and gas separation characteristics, particularly permeability of carbon dioxide (CO2) and separation characteristics of carbon dioxide and methane (CH4), at such a high level that has not hitherto been achieved. The gas separation membrane was obtained by heat treating a membrane composed of a hyperbranched polyimide-based material in a non-oxidizing atmosphere.
