摘要:
The fuel cell vehicle includes a fuel cell for generating electric power by electrochemical reaction of hydrogen and oxygen, and a hydrogen tank which stores pressurized hydrogen to supply hydrogen to the fuel cell, the fuel cell and the hydrogen tank being arranged at an underfloor region of the vehicle. Based on the detection results in a side G sensor arranged on the side of the fuel cell and a rear G sensor arranged on the side of the hydrogen tank, a side air bag device is made expandable and a cut-off valve and a contactor are operated to cut off.

The invention provides a method for manufacturing printed wiring substrates which can manufacture printed wiring substrates each having resin dielectric layers of uniform thickness and excellent surface flatness while maintaining favorable cutting performance in a dicing step. A multi-printed wiring-substrate panel is manufactured which includes a metal plate having a first main surface and a second main surface, and resin dielectric layers disposed on the first and second main surfaces. The metal plate has first depression portions and second depression portions. The first depression portions are opened at the first main surface and arranged discontinuously along predetermined cutting lines. The second depression portions are opened at the second main surface and arranged discontinuously along the predetermined cutting lines. The multi-printed wiring-substrate panel is cut along the predetermined cutting lines into a plurality of printed wiring substrates.

A method for fabricating a component board which includes forming a first main-face-side Au plating layer on surfaces of main-face-side connection terminals and a first back-face-side Au plating layer on surfaces of back-face-side connection terminals of the component board; covering the first main-face-side Au plating layer with a protection layer; forming a second back-face-side Au plating layer on the first back-face-side Au plating layer; and removing the protection layer after completing the second Au plating step. Alternatively, the first back-face-side Au plating layer may be removed after completing the masking step. Displacement Au plating is used as the first and second Au plating.

A printed-wiring substrate 1 includes internal dielectric resin layers 12 and 14. A main-surface-side external dielectric resin layer 13 is formed on the internal dielectric resin layer 12 such that the surface thereof serves as a substrate main-surface 1A. A back-surface-side external dielectric resin layer 15 is formed on the internal dielectric resin layer 14 such that the surface thereof serves as a substrate back-surface 1B. A surface 12A of the main-surface-side internal dielectric resin layer 12 and a surface 14A of the back-surface-side internal dielectric resin layer 14 are roughened. The substrate main-surface 1A and the substrate back-surface 1B are roughened such that surface roughness thereof is lower than that of the surfaces 12A and 14A.

In an apparatus for controlling an autonomous operating vehicle having an operating machine and a magnetic sensor adapted to detect a border of a travel-scheduled area, the vehicle is controlled to travel around the area from a start point along the border to sequentially record traveling directions and traveled distances on a bitmap. The generated travel trajectory is transformed to map information. A position of the vehicle is detected using bits of the bitmap of the transformed map information, and the vehicle is controlled to, as traveling straight in the north-south directions, while perform the operation with the operating machine based on the calculated traveling direction, the calculated traveled distance and the determined position, utilizing a primary reference direction obtained from a geomagnetic sensor as a reference.

Fuel supply station information distributing system includes at least one vehicle, an information distributing server and at least one station, which are interconnected through communication line networks. The information distributing server transmits at every given time a request-to-send for vehicle information to the vehicles as well as a request-to-send for station information to the stations. The information distributing server then creates a fuel supply station information associating for each vehicle based on the vehicle information received from the vehicle and the station information received from the stations, and distributes it to the vehicle. When the vehicle receives the fuel supply station information from the information distributing server, it is displayed on the car navigation screen for notifying the driver.
