  • Patent number: 10684672
    Abstract: A memory system includes a nonvolatile semiconductor memory, and a controller circuit that includes a physical layer and is configured to store information defining a plurality of low power consumption modes for setting the physical layer to a low power consumption state while controlling the physical layer according to a first standard, and control input and output of signals between the physical layer and the nonvolatile semiconductor memory according to a second standard. The controller circuit selects one of the low power consumption modes based on a data transfer state of the physical layer.

  • Patent number: 7822014
    Abstract: A voice communication system transfers voice information stored in a protocol data unit under a predetermined communication protocol over a network, and includes end voice terminals for transferring and receiving the voice information, and a management server for managing said end voice terminal. The management server includes a manager for storing subscriber information indicative of whether or not the end voice terminals are provided with the capability of predetermined broadband voice communication. A user is informed, at the latest before the user initiates a call from the end voice terminal, of whether or not a telephone set of a called party is provided with the capability of the broadband voice communication through the end voice terminal based on the subscriber information. running in a network under a predetermined communication. This increases the satisfaction of the user and allows a business model justifying charging customers to be built.

  • Patent number: 6466451
    Abstract: A MOSFET 150 composed of a bare tip is surface mounted on a bus bar 141 disposed on the surface of an insulated plate 140, and the MOSFET 150 is circuit connected to a bus bar substrate 14 or to a printed circuit board 145 disposed integrally on the bus bar substrate 14 through a wire 151. In the bus bar 141, there is disposed a heat radiating member 155 which is used to radiate heat generated from the MOSFET 150 into an external space.

  • Patent number: 6369460
    Abstract: A power supply monitoring apparatus, for which a plurality of different preset reference current values and corresponding permitted times are provided, includes: a cutoff device; current detection circuits; overcurrent detection circuits; an idle-up command circuit; and a low voltage detection circuit. When an overcurrent detection circuit detects a current value equaling or exceeding at least one of the preset reference current values, and when that condition continues for a time equaling or exceeding a permitted time corresponding to the pertinent reference current value, the circuit transmits a command to the cutoff device to interrupt the current supplied to a power feeding path. Further, when the idle-up command circuit detects an increase in a supplied current, an idle-up command is issued.

  • Patent number: 6238221
    Abstract: To provide a circuit connection structure for a junction block which can improve the reliability in circuit connection while trying to reduce a space needed for circuit connection. A wiring pattern 11 is provided on a printed-wiring board 10, and electronic components 12 are mounted on the printed-wiring circuit board 10. A slit 13 is formed in a substrate main body 10a of the printed-wiring board 10, and a land portion 14 is provided on each side of the slit 13. The land portion 14 is connected to the wiring pattern 11. A single-core wire 15 is disposed so as to extend between the land portions 14 and is soldered thereat. One end portion of a pressure connecting terminal 18 is pressure connected to a single-core wire 17 within a junction block, while the other end portion of the pressure connecting terminal 18 is bite connected to the single-core wire 17 through the slit 13.
