  • Patent number: 8036779
    Abstract: In an air-conditioning system controller provided with a central control unit and a local control unit, the central control unit includes a heat source machine measurement system for measuring an input/output state of a heat source machine, a setting unit for setting air-conditioning condition data on air-conditioning object spaces, an outdoor air measurement system for measuring outdoor air condition data, a total air-conditioning load operating unit, an optimal operating state estimation unit, and a heat source machine control. The total air-conditioning load operating unit calculates a total air-conditioning load or a heat exchange rate of the heat source machine based on chilled water inlet and outlet temperatures and chilled water flow rate of the heat source machine.

  • Patent number: 7874582
    Abstract: A child seat installation structure is disclosed in which it is prevented that an expandable portion, when it expands, interferes with a child seat. In one form, an airbelt includes a lap bag and a normal belt portion, a tip of which is connected to the lap bag. A bracket for fixing a tip side of the normal belt portion is provided on a lap anchor. A loop portion is formed on the tip side of the normal belt portion using a clip, and the loop portion is inserted into a fixing hole provided in the bracket and is locked with a lock member. After that, a child seat is placed on a seat, and only the normal belt portion is routed over the child seat.

  • Patent number: 7766382
    Abstract: A predetermined tension force is generated to an air belt even when an expandable portion is expanded in a narrow space. An air belt 30 includes a first normal belt 31, a second normal belt 32, and an expandable portion 33 therebetween. In order to regulate a thickness of the expandable portion 33 in an expanding operation, portions of the expandable portion 33 facing each other are coupled by means of a coupling portion 34 formed of a stitching thread. The expandable portion 33 includes a bag-shaped belt 33a and a knit cover 33b that is not extended in a longitudinal direction. When an inflator is operated, the expandable portion 33 is expanded and the air belt 30 fits an occupant. At this moment, since the knit cover of the expandable portion 33 is not extended in the longitudinal direction of the air belt 30, a length of the expandable portion 33 is reduced along with an expansion of the expandable portion 33 and the tension force is generated to the air belt 30.

  • Publication number: 20100123349
    Abstract: A seat belt retractor for retracting a seat belt includes a spool for retracting the seat belt, a locking mechanism for locking rotation of said spool, and an end-lock preventing mechanism for preventing an end-lock of the seat belt. The end-lock preventing mechanism includes a first speed-reduction portion for largely reducing a seat belt retracting speed of the spool when the spool retracts a substantially full length of the seat belt, and a second speed-reduction portion for reducing the seat belt retracting speed less than that of the first speed-reduction portion so as to provide a delay for the locking mechanism to be brought to a non-lock position at least when retraction of the seat belt is finished.

  • Patent number: 7669895
    Abstract: A knee-bag to be inflated in front of an occupant leg includes a first member facing the occupant, a second member facing the first member, and a tether provided in the knee-bag for connecting the first member and the second member. The tether extends in a lateral direction and has end portions in a thickness direction of the knee-bag, and lateral ends in the lateral direction. At least one of the lateral ends has a portion located inwardly in the lateral direction so that air-flow spaces are formed between a left end of the tether and a left side of the knee-bag and between a right end of the tether and a right side of the knee-bag.

  • Patent number: 7613885
    Abstract: In a multi-processor system, counting snoop results bottlenecks the broadcast-based snoop protocol. The directory-based protocol delays the latency when remote node caches data. There is a need for shortening the memory access latency using a snoop and cache copy tag information. When the local node's cache copy tag information is available, the memory access latency can be shortened by omitting a process to count snoop results. When memory position information is used to update the cache copy tag during cache replacement, it is possible to increase a ratio to hit a copy tag during reaccess from the local node.

  • Patent number: 7441860
    Abstract: When a printing requirement is made, in the case where the internal temperature of a printer is equal to or lower than 40° C., print data is to be generated using a LUT for a normal state (S170), while in the case where the temperature is higher than 40° C., the user is allowed to select a subsequent operation via a high-temperature state selection screen (S120 and S130). When a print continuation button is pressed, print data is to be generated using a LUT for a high-temperature state (S180), while when a print standby button is pressed, a cooling command is to be sent out, and then print data is to be generated using the LUT for a normal state after waiting until the internal temperature becomes lower than 40° C. (S140 to S170).
