PROBLEM TO BE SOLVED: To realize an antenna which is suited to diversity reception or the like, can be easily mounted on a resin-made body of a vehicle or the like and is excellent in directivity.SOLUTION: In the constitution of loading a short-circuit stab 21 serially to the antenna, a point b at w ...
Disclosed is a gas valve capable of switching gases to be introduced within a vacuum chamber with high speed thereby enhancing the controllability of the composion of a semiconducting thin film growing on a substrate and shortening the time required for growth of the thin film. The gas valve compris ...
The disclosed apparatus detects an imminent collision between a vehicle and an object, by orienting respective receiver and transmitter antennas, mounted on the vehicle, so their patterns intersect and form a crash detecting zone just ahead of the vehicle, and by deriving the relative speed between ...
A safety device for vehicle passengers, of the type in which at least one air bag is inflated responsive to detection of an object in the vehicle path in advance of contact of the vehicle with the object, includes a source of fluid under pressure and a valve, operable responsive to detection of such ...
Provided are a agricultural chemical composition which comprises a first component having herbicidal activity selected from the group consisting of glyphosate and the like and a second component selected from the group consisting of phosphorous acid derivatives and the like and may further comprise ...
In mobile communications, it is required that the beam direction is maintained to track the desired direction as the mobile is moving. For such a purpose, the mobile includes an angular rate sensor mounted therein which detects the state of turn in the mobile and to control the beam direction of the ...
PROBLEM TO BE SOLVED: To improve a gain in a CRLH leakage-wave antenna.SOLUTION: In the leakage-wave antenna 100; a section 23i forming a capacitor, a transmission line 21i, sections (stubs) 24i and 25i forming an inductor, and the section 22i forming the capacitor form a first repeating unit (an an ...
PROBLEM TO BE SOLVED: To provide a small-sized array antenna by which the scan control or shape control of electromagnetic beams is easy and high gain is obtained easily, even in a high-frequency band of 1 GHz or higher.SOLUTION: A grounding conductor g1 of a first ground area (0≤y≤a) has slits s1 a ...
In a method for protecting passengers in a moving vehicle, radio signals having a predetermined propagation speed and frequency are transmitted from the moving vehicle to an approaching object, such as a second vehicle. Radio signals reflected from the approaching object, and having a different freq ...
