  • Patent number: 6953968
    Abstract: A semiconductor device of the present invention has an insulating gate type field effect transistor portion having an n-type emitter region (3) and an n? silicon substrate (1), which are opposed to each other sandwiching a p-type body region (2), as well as a gate electrode (5a) which is opposed to p-type body region (2) sandwiching a gate insulating film (4a), and also has a stabilizing plate (5b). This stabilizing plate (5b) is made of a conductor or a semiconductor, is opposed to n? silicon substrate (1) sandwiching an insulating film (4, 4b) for a plate, and forms together with n? silicon substrate (1), a capacitor. This stabilizing plate capacitor formed between stabilizing plate (5b) and n? silicon substrate (1) has a capacitance greater than that of the gate-drain capacitor formed between gate electrode (5a) and n? silicon substrate (1).

  • Publication number: 20050218211
    Abstract: Conventionally, obtaining both information regarding use of a credit card and information regarding an account to which credit card payment is debited is not considered. For instance, when paying by credit using a communication terminal device, obtaining information regarding a payment amount and information regarding a bank balance is not considered. Thus, a communication terminal device capable of transmitting/receiving data, comprises: a communication portion transmitting/receiving data; a display portion displaying information received by the communication portion; and a control portion controlling the communication portion and display portion, wherein the communication portion receives card use information from a server of a card company and account information from a server of a financial institution; and wherein the control portion operates to display the card use information and the account information side-by-side on the display portion.

  • Publication number: 20050093692
    Abstract: In an information processing device of the present invention, the current position of the information processing device is obtained by a communication unit and a position information obtaining unit. Information on a device used by a user and information on his operation are obtained by an act detection unit. Act information describing when, where, and what operation the user is prohibited or permitted to perform is obtained by an act information list obtaining unit. A match determination unit determines whether the user has performed an act associated with the act information, and whether the current position of the information processing device matches the position included in the act information and a current time matches the time included in the act information. An act notification unit reproduces a message included in the act information and automatically notifies others of performance of the act using the communication unit.

  • Patent number: 6876618
    Abstract: A signal is reproduced from a recording medium. The reproduced signal is sampled in response to a clock signal to get a sampling-resultant signal. A transversal filter includes a delay line having taps and delaying the sampling-resultant signal, multipliers for multiplying only alternate ones among signals appearing at the taps by tap coefficients to get multiplication results, and an adder for adding the multiplication results into a filtering-resultant signal. A temporary decision device operates for calculating a temporary decision value of the filtering-resultant signal according to a temporary decision procedure, for calculating a difference between the temporary decision value of the filtering-resultant signal and an actual value thereof, and for generating an error signal in response to the calculated difference. The tap coefficients used in the transversal filter are controlled in response to the error signal and the reproduced signal to minimize the error signal.

  • Publication number: 20040117855
    Abstract: A tuner receives service information SI for each of a plurality of channels included in a digital broadcasting signal at one carrier frequency. A service information extraction unit extracts and stores the received service information preset into a memory. The operator selects the service information stored in the memory and acquires a program. The tuner may have a function of automatically scanning the carrier frequency all over the receivable frequency bands and store it. The temporary service information having irregular broadcast time is stored in the memory through an operation of an operation input unit. When the temporary service information is not broadcast, such temporary service information is deleted from the memory.
