  • Patent number: 10547147
    Abstract: The invention provides a plug connector which, when abnormal heating occurs in a fitting portion with a counter connector, can sensitively cut off the current supply. The plug connector has: contacts; a body that holds the contacts; a metal shell that covers the body; and a printed circuit board on which the contacts are solder-connected. The body has a fitting portion with a counter connector. The board has a thermal protection circuit. The thermal protection circuit has a temperature switch that detects a temperature, and an FET that is disposed in a power supply wiring of the board. When the detected temperature of the temperature switch exceeds a predetermined temperature, the power supply wiring is cut off by the FET. In the plug connector, the board has a heat conduction pattern that conducts heat of the metal shell 60 to the temperature switch.

  • Publication number: 20090247572
    Abstract: It is intended to provide an agent for treating atrial fibrillation, comprising an If current inhibitor as an active ingredient. In the present invention, the means for resolution comprises an agent for treating atrial fibrillation, comprising an If current inhibitor as an active ingredient. In particular, it comprises an agent for treating atrial fibrillation comprising (?)-N-{2-[(R)-3-(6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline-2-carbonyl)piperidino]ethyl}-4-fluorobenzamide monophosphate as an active ingredient. The active ingredient according to the present invention has more preferred properties for use as an agent for treating atrial fibrillation compared to Verapamil (a Ca antagonist) and Atenolol (a ?-blocker) which have been conventionally used as the agents for treating atrial fibrillation.

  • Patent number: 7519403
    Abstract: Disclosed is a mobile terminal capable of receiving a broadcast signal, in which two housings are joined. The mobile terminal includes a relative position detecting unit for detecting a change in relative position of the two housings, and a control unit to control recording and playing back of a broadcast program based on detection result. When a change in the relative positions of the two housings is detected during viewing or listening to a broadcast program under reception in a use state, viewing or listening is interrupted and recording in a memory is started, and when the use state is detected again, viewing or listening is resumed from a interrupted timing while continuing record.

  • Patent number: 6996407
    Abstract: A shared-use portable telephone has a ROM, RAM and control sections. The ROM section comprises a password area for holding passwords and a personal information area for holding personal information. The password and personal information areas include respective sub-areas that a plurality of users can utilize, respectively, based on their passwords. The control section copies the personal information stored in the personal information sub-areas to the RAM section that the users use in common and then to the personal information sub-area of the ROM section. The personal information sub-areas of the ROM section are used independently of each other, one for each user and never for any other user. Every time the portable telephone is used, the information stored in the RAM section is copied into the specific area of the ROM section. Each user can access his or her personal information, but cannot access the personal information of the other users.

  • Patent number: 6327483
    Abstract: A level detector 81 detects and calculates a power value A1 of a d.c. component of a transmitting audio signal. A subtractor 82 calculates a difference between a transmitting power value A1 and a reference power value A0 written in a memory 14 to obtain an amplification degree A2 which is temporarily stored in a memory portion 11. When a receiving audio signal is inputted through an audio signal processing portion 5 to an amplifier 83 of a signal comparator portion 8 at a next timing, the amplification degree A2 of the receiving sound read out from the memory portion 11 is read out to variably control a gain of the amplifier 83 to thereby amplify the receiving audio signal A2 times. Thus, a receiving sound volume can be variably regulated according to a transmitting sound volume.

  • Patent number: 5883892
    Abstract: In a storage type data communication terminal, a first switch section is connected to a power feeder and turned on/off by an operator. A second switch section is connected in parallel with the first switch section and turned on/off in accordance with a control signal. An external interface section performs connection to an external information processing device. A data storage section temporarily stores data received through the external interface section. An Air interface section sequentially transmits the data stored in the data storage section to a distant station through a communication channel in accordance with a communication sequence, and stores data received from the distant station. A control section switches the second switch section from an OFF state to an ON state at the same time when a connection phase of the communication sequence is completed.
