  • Patent number: 9732975
    Abstract: There is provided an air-conditioning system in which at least one or some of a plurality of air-conditioning apparatuses are each controllable such that the indoor temperature is maintained between two set temperatures. All the plurality of air-conditioning apparatuses are switched to either one of heating operation and cooling operation on the basis of a temperature difference between the indoor temperature related to an air-conditioning apparatus that is in the first operation mode and a set target temperature and a temperature difference between the indoor temperature related to an air-conditioning apparatuses that is in the second operation mode and an upper temperature limit or a lower temperature limit.

  • Patent number: 8141902
    Abstract: An airbag (10) has a vent hole (18) in one side end portion. One end of a third base fabric (20) is sewn to the airbag (10) through a first sewn portion (23) that closes the vent hole (18), and the other end of the third base fabric 20 is sewn to the other side end portion of the airbag (10) through a second sewn portion (24). The first sewn portion (23) has weaker binding force by sewing than the second sewn portion (24) so that the first sewn portion (23) is separated to open the vent hole (18) when tension force is applied from the third base fabric (20) to the first and second sewn portions (23) and (24).

  • Patent number: 7856568
    Abstract: An electronic apparatus (200) comprises processors (20)-(22), devices (30)-(33), and a peak power-managing unit (10). The peak power-managing unit (10) includes a power information storage unit (11) operable to store a total power consumption value, and a suspended request storage unit (12) operable to store suspended use requests. Each of the processors (20)-(22) addresses, to the peak power-managing unit (10), a use request for the use of a target device among the devices (30)-(33). The peak power-managing unit (10) issues a device use permit notification to the processor when determining that the operation of the target device still maintains an added total power consumption value within a specified value. Upon receipt of the device use permit notification, the processor sets up a course of action to be provided by the target device. As a result, controlled peak power is provided, and the devices can be run according to updated information.

  • Patent number: 6697994
    Abstract: Shift register stores data read from data memory through data bus, and supplies a shift output to shift register. Shift register stores operation target data read from data memory through data bus, shifts operation target data one bit by one bit, and supplies operation target data to bit selection circuit. Bit selection circuit selects bit data, which is placed at a position designated by register, from data stored in shift register. Multi-input exclusive OR circuit executes exclusive OR operations of all bits of bit data output from bit selection circuit, simultaneously, and outputs an operation result of one bit to shift register. This makes it possible to efficiently perform convolutional code processing at high speed.

  • Patent number: 6523892
    Abstract: A headrest movable frame (2) has an upper frame (2b) which is arranged on the upper end face of a seatback and extends in the widthwise direction of the vehicle body, and side frames (10) which are arranged on the side end faces of the seatback and extend in the up-and-down direction. A lower frame (2c) is axially supported on the side frames (10) at a position below the upper frame (2b). Guide holes (3) linearly move a headrest (1) upward and forward by a backward load acting on the lower portion of the lower frame (2c) of the headrest movable frame (2) in a rear impact collision.

  • Patent number: 6471238
    Abstract: An air-bag 12 is designed to vertically expand after transversely expanding while being inflated. The air-bag 12 having a substantially circular shape is folded from its opposite ends toward its middle along a direction “a” corresponding to vertical direction and rolled in an opposite direction, is then folded in a zigzag manner one fold over another from its opposite ends toward its middle along a direction “b” (transverse direction), and is accommodated in a container casing 14. Accordingly, the inventive air-bag device and air-bag folding method can suppress an inflation (expansion) of the air-bag toward a passenger at an early stage of the inflation of the air-bag, promote a transverse expansion more than a vertical expansion of the air-bag at the early stage of the inflation, and prevent a blow out of a gas toward the passenger.
