20100026598 | SATELLITE BROADCAST RECEIVING CONVERTER - A satellite broadcast receiving converter is provided with a feedhorn to which a satellite broadcast wave is input, a circuit board on which a converting circuit to convert the satellite broadcast wave to a receiving signal is formed, and a converter case disposed on a back end side of the feedhorn to support the circuit board. The converter case is comprised of two case members configured to cover and shield the front and back surfaces of the circuit board, and to be able to hold the circuit board. A first case member of the two case members is integrally formed with the feedhorn. | 02-04-2010 |
20100045566 | SATELLITE BROADCAST RECEIVING CONVERTER - A satellite broadcast receiving converter includes a feedhorn to which a satellite broadcast radio wave is input, a circuit board on which a converting element for receiving and converting the satellite broadcast radio wave to an electric signal is mounted, and a support case which is provided on the periphery on the back end side of the feedhorn, and which supports and positions the circuit board at a position at which the satellite broadcast radio wave can be received. The feedhorn and the support case are made of synthetic resin formed by plating a surface of the synthetic resin with metal. At least the opening surface side surface and the inner side surface which serves as a waveguide path of the feedhorn are plated with metal. At least the inner side surface of the support case positioned between the inner wall of the feedhorn and a ground pattern of the circuit board is plated with metal. Further, the cross-sectional surface of a corner section surrounded by two or more wall surfaces of the metal-plated sections of the feedhorn and the support case is formed into an arc shape so as not to allow an air space to be formed at the time of plating. | 02-25-2010 |

20090115419 | APPARATUS FOR ESTIMATING CHARGED STATE OF ON-VEHICLE BATTERY - An apparatus is provided to estimate a charged state of a vehicle provided with an internal combustion engine having a crankshaft, a starter that initially rotates the crankshaft when the engine is started, and a battery that powers the starter. The apparatus comprises a detection device and an acquisition device. The detection device detects a voltage of the battery and a discharge current from the battery for a period of time over time instants before and after starting the engine. The acquisition device acquires information indicative of an amount of the discharge current from the battery when the detected voltage of the battery becomes a minimum due to starting the engine. | 05-07-2009 |
