  • Patent number: 6962145
    Abstract: A failure detection apparatus for an internal combustion engine includes failure detecting means (S22-S30) for detecting abnormality of fresh air quantity detecting means (air flow sensor) based on the result of comparison between a fresh air quantity detected by the fresh air quantity detecting means (air flow sensor) and a fresh air quantity reference value set by fresh air quantity reference value setting means (S20), and exhaust flow rate adjusting means. The fresh air quantity reference value setting means sets the reference value (S16) in accordance with not only the operating state (engine speed Ne, fuel injection quantity Qf, etc.) of the engine but also a target adjustment amount (target throttle valve opening) set for the exhaust flow rate adjusting means by target adjustment setting means (S12, S14).

  • Patent number: 6905063
    Abstract: A semiconductor device can be formed with fewer voids in the solder bonding a laminate of a silicon chip, an insulator substrate, and a metal base, with a solder layer positioned between the layers. After placing the laminate in a furnace, it is evacuated and then pressurized with hydrogen gas, and then heated to melt the solder. While maintaining the heat, the furnace is again evacuated to remove voids in the solder, and then the furnace is positively pressurized again with hydrogen gas to prevent holes produced by the voids traveling in the solder, and to obtain a uniform solder fillet shape. Thereafter the laminate is rapidly cooled to obtain a finer grain solder to increase the rate of creep to quickly remove the warping of the laminate to the original state.

  • Patent number: 6873855
    Abstract: A radio telephone system includes a base station and a plurality of mobile stations. The base station transmits echo-back request signals to the mobile stations in turn. When the mobile station fails to transmit an echo-back response signal, the base station determines that the non-responsive mobile station is outside a radio zone of the base station, and deletes the corresponding data from a storage section thereof. Further, the base station is capable of changing its transmission power level so as to change a size of the radio zone correspondingly. Specifically, the base station monitors a range of presence of the mobile stations within the radio zone, and changes its transmission power level depending on such a range. For example, when such a range spreads over the radio zone, the base station may control its transmission power level to be maximum. On the other hand, when such a range is only around the base station, the base station may control its transmission power level to be minimum.

  • Patent number: 6846979
    Abstract: A search list of records is displayed on a display screen DP. Some records may have the same music title as one item, but are different in other items (genre, rhythm, tempo and the like). A favorite list can be formed by a selection process using a mark FMa (reversible by a favorite switch ST0) on each record. A first or second list can be formed by a search process after a search switch SM5 or ST5 is operated. A desired list is selected by using list selection switches ST1 to ST4 and a desired record is designated by a cursor CR to decide a style. The cursor CR can be moved by one record after another by a normal cursor motion switch SM2 or SM3, and jumped to a record group having different item contents by a special cursor motion switch SM1 or SM4.

  • Patent number: 6844621
    Abstract: A semiconductor device has an insulating substrate with conductor patterns bonded to and formed on both the top and bottom surfaces of a ceramic substrate. Soldering is provided between the conductor pattern on the top surface side and a heat developing chip component such as a power semiconductor element is mounted thereon. Between the conductor pattern on the bottom surface side and a heat dissipating metal base plate, each of four corners of the ceramic substrate is chamfered to form a chamfered section with a chamfered dimension of 2 to 10 mm. Alternatively, slits can be formed at the four corners on the bottom surface side. Moreover, the thickness of the conductor patterns can be controlled in relation to the ceramic substrate. These configurations relax the stress concentration created in the soldered section due to a thermal cycle.
