20100201595 | REFLECTOR ANTENNA, METHOD OF FEEDING SAME, AND COMMUNICATION SYSTEM - A reflector antenna includes a reflector, a primary radiator, an arm, and a feed unit (a coaxial cable and a coaxial connector). The reflector has a reflecting surface for reflecting a radio wave, and the reflecting surface is shaped as a paraboloid of revolution. The primary radiator is arranged on a focus side of the reflector, and radiates a radio wave from the focus side toward the reflecting surface. The arm is arranged to extend from the reflecting surface side to the focus side of the reflector, and supports the primary radiator so as to be rotatable with respect to the reflector. The feed unit feeds the primary radiator via the arm so that the direction of the arm and the direction of polarization of the radio wave radiated from the primary radiator are perpendicular to each other. | 08-12-2010 |
20100245187 | PARABOLA ANTENNA - Provided is a parabolic antenna that suppresses leakage of radio waves with a simpler configuration. The parabolic antenna includes a horn that transmits and receives signals; a feed that supports the horn and relays the signals the horn transmits and receives; a reflector that reflects the received signals to focus the received signals on the horn and reflects the signals from the horn to transmit the signals; a reflecting mirror supporting member that supports the reflector; and a feed fitting adapter that enables the feed to be fitted into the reflecting mirror supporting member. A choke groove is formed in at least one of a joint area between the reflecting mirror supporting member and the reflector and a joint area between the reflecting mirror supporting member and the feed fitting adapter, which suppresses propagation of radio waves traveling through the gap of the joint area. | 09-30-2010 |
20110234468 | ANTENNA DEVICE AND COMMUNICATION DEVICE PROVIDED THEREWITH - An antenna device includes a concave-shaped reflecting mirror that reflects radio waves, a primary radiator disposed in the concave mirror and transmitting/receiving radio waves, and an antenna cover attached to an opening face of the reflecting mirror. The antenna cover is secured to the reflecting mirror with a flange part formed on the rim of the antenna cover and fitted to the inner side of a flange part formed on the rim of the reflecting mirror. | 09-29-2011 |

20090151695 | Method and apparatus for controlling ingition timing of an internal combustion engine based on engine rotary speed - An engine ignition control apparatus includes a standard ignition map for use in retarding ignition timing when a throttle opening is within a predetermined range, and when an engine speed is within a predetermined region; and an acceleration-time advance angle correction quantity map for performing advance angle correction when the engine speed is within the predetermined region; an engine accelerometer for detecting a rate of change of the engine rotary speed; and an acceleration-time advance angle correction quantity setting unit for correcting an advance angle of the ignition timing. When the engine speed is within the predetermined range, and the rate of change of engine rotary speed is greater than or equal a predetermined rate, the acceleration-time advance angle correction quantity setting unit performs attenuation processing for deriving an advance angle correction quantity; and increases an attenuation quantity of the advance angle quantity for every ignition. | 06-18-2009 |
20090157279 | Fuel injection control device and method for continuously controlling fuel injection during engine operation based on throttle position - A fuel injection control device includes a basic-injection-use map for deriving a basic injection amount and an additional-injection-use map for deriving an additional injection amount, each corresponding to the throttle opening. During operation of the engine, in each engine cycle, a first calculation stage for calculating the basic injection amount, and a second calculation stage provided after the first calculation stage are set. A first injection amount and a second injection amount obtained by applying the throttle opening measured in the first calculation stage and the second calculation stage, respectively, are compared. When the second injection amount is greater than the first injection amount, an additional injection amount is calculated by subtracting the first injection amount from the second injection amount; and when the first injection amount is greater than the second injection amount, the basic injection amount calculated in the first calculation stage is corrected. | 06-18-2009 |
20090241649 | Method and system for detecting a crank angle of an engine - A method and a system for detecting a crank angle of an engine includes detecting a non-toothed portion of a crank pulse rotor during a inlet valve open period for preventing falsely recognizing compression top dead center as a position of the non-toothed portion. A crank angle sensor is arranged at a position facing an outer circumference of a crank pulse rotor including a non-toothed portion thereof. An interval calculating unit measures crank pulse time intervals between adjacent teeth based on a sensing signal received from the crank angle sensor. The measured successive crank pulse time intervals are compared for detection of the non-toothed portion. A ratio calculating unit calculates a ratio of crank pulse intervals. A maximum ratio detecting unit determines presence of the non-toothed portion when the calculated ratio of crank pulse interval is the maximum in the cycle of the engine. | 10-01-2009 |
