Makio Tsuchiya has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8766865
    Abstract: An antenna device including: a reflector antenna including a primary radiator, a feed waveguide for feeding radio waves to the primary radiator, and a reflector; and a radome that covers the reflector antenna, in which the antenna device further includes a sidelobe reduction member attached to a vicinity of the primary radiator or the feed waveguide, the sidelobe reduction member reducing a sidelobe in a specific direction of an antenna by at least one of scattering and absorbing of radio waves reflected by the radome out of the radio waves radiated from the reflector antenna. Therefore, it is possible to reduce a sidelobe deterioration caused by reflection waves from the radome.
    Type: Grant

  • Patent number: 5535430
    Abstract: A mobile communication terminal equipment is mounted in a vehicle and can utilize both the satellite and terrestrial communication systems. The mobile communication terminal equipment includes a satellite transceiver and a portable set. The satellite transceiver has a satellite transmission/reception circuit. As required, the portable set is disconnected from the satellite transceiver to be carried by the user. The portable set includes a terrestrial transmission/reception circuit, a signal input/output circuit and a connection selecting switch. The connection selecting switch is automatically controlled to connect the signal input/output circuit selectively to one of the satellite and terrestrial transmission/reception circuits. When the satellite transmission/reception circuit is in connection with the signal input/output circuit, the communication through the satellite wireless communication system can be carried out.
