Patents by Inventor Kenichiro Kodama

Kenichiro Kodama 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: 8290550
    Abstract: An electromagnetic field strength reducing device includes a high-frequency wave eliminator that eliminates a high frequency component from an electrical signal input from a signal source. An electrical signal line is disposed between the high-frequency wave eliminator and the electrical member so as to convey the electrical signal with the high frequency component eliminated to an electrical member. The device also includes a resonant-frequency regulator connected between the electrical signal line and ground to cause the electrical signal line to be resonant at a frequency used for radio communication. The electromagnetic field strength reducing device may be employed in a portable electronic device with a HAC standard radio frequency communication compliance requirement, and use a corresponding method to eliminate the high frequency component.

  • Publication number: 20090027138
    Abstract: A switch circuit including: a plurality of MEMS switches connected in parallel or in series, which have different drive voltages; and a single voltage supply for driving the plurality of MEMS switches by the plurality of drive voltages, is used for a microwave circuit or an antenna circuit, to vary a configuration of the microwave circuit or the antenna circuit based on the drive voltage value. That is, the configuration of the microwave circuit or the antenna circuit can be varied based on the drive voltage value by using the switch circuit including the MEMS switches having the different drive voltages for the microwave circuit or the antenna circuit.

  • Patent number: 4123477
    Abstract: Greatly improved heat and light resistance is imparted to polyvinylidene chloride resins by incorporating therein a specific chlorinated ethylene-vinyl ester copolymer to minimize the quantities in said resins of conventional additives, of which migration is undesirable from a viewpoint of food hygiene. The resulting polyvinylidene chloride resin compositions also have excellent gas barrier properties and high transparency.
