  • Patent number: 7218728
    Abstract: A power source is turned on by pressing a power source button in a key input part. Then, a telephone number is inputted from the ten keys in the key input part so that the telephone number is stored in a telephone number temporary memory part. After pressing a communication button in the key input part, conversation is held with the counterpart. Then, a finish button is pressed for finishing the communication. When it is finished, a list of telephone directories is displayed on a display device. In the case the input from the ten keys is the number information, the telephone directory for registration is selected from the “telephone directories 1 to 4” with different functions such that if the input is the number “1”, the telephone directory 1” is selected, and if it is the number “2”, the telephone directory 2” is selected. Furthermore, in the case of adding the name information to the telephone number, registration is executed in the selected telephone directory with the name information.

  • Patent number: 6952670
    Abstract: An extraction section extracts a speech signal having ambient noise superimposed thereon as a data segment having a predetermined duration. An autocorrelation function normalizing section determines normalized autocorrelation function vectors. A normalized autocorrelation function count section counts a given number of normalized autocorrelation function vectors. A noise vector region/speech vector region/undefined vector computation section classifies the normalized autocorrelation function vectors into any of a noise vector region, a speech vector region, or undefined vectors. When the latest normalized autocorrelation function vector acquired by a normalized autocorrelation function vector determination section pertains to the noise vector region, the speech signal is determined to be a noise segment. In contrast, when the latest vector does not pertain to the noise vector region, the input signal is determined to be a speech segment.

  • Patent number: 5442812
    Abstract: An antenna switching apparatus for selectively connecting an antenna to either a transmitter for transmitting a transmitting signal having a transmitting frequency, or a receiver for receiving a receiving signal having a receiving frequency, which is different from the transmitting frequency, includes an antenna terminal electrically connected to the antenna; a transmitting terminal electrically connected to the transmitter, and a receiving terminal electrically connected to the receiver. A receiving filter for passing a receiving signal therethrough is electrically connected between the antenna terminal and the receiving terminal. An impedance adjusting element is electrically connected to an input end of the receiving filter, and has an element value such that an impedance when seen from the antenna terminal looking toward the receiving filter becomes substantially infinity at the transmitting frequency.

  • Patent number: 4476629
    Abstract: A method and apparatus for automatically producing a wire harness. A plurality of wiring blocks are arranged on a workbench. Each wiring block has a wire clamping section, a wire cutting section, and a terminal press attaching section. The wire cutting section and the terminal press attaching section can be separated from the wire clamping section. This structure makes it possible to automate a series of operations including wire cutting, wire peeling, and terminal attaching operations.
