  • Patent number: 8269967
    Abstract: A method of attaching an object to be measured to a structure causing a diffraction phenomenon; irradiating the structure to which the object to be measured is attached and which causes the diffraction phenomenon with an electromagnetic wave; detecting the electromagnetic wave scattered by the structure causing the diffraction phenomenon; and measuring a characteristic of the object to be measured from the frequency characteristic of the detected electromagnetic wave. The object to be measured is attached directly to the surface of the structure causing the diffraction phenomenon. Thus, the method for measuring the characteristic of an object to be measured exhibits an improved measurement sensitivity and high reproducibility. A structure causing a diffraction phenomenon and used for the method, and a measuring device are provided.

  • Publication number: 20120067059
    Abstract: A process for removing carbon dioxide from a fluid comprises the steps of: (a) treating the fluid by bringing it into countercurrent contact with a liquid absorbent in a first absorption zone and thereafter in a second absorption zone to absorb at least part of the carbon dioxide contained in the fluid into the absorbent; (b) depressurizing the loaded absorbent to release a first stream of carbon dioxide and yield a partially regenerated absorbent; (c) recycling a first stream of the partially regenerated absorbent into the first absorption zone; (d) heating a second stream of the partially regenerated absorbent to release a second stream of carbon dioxide and yield a regenerated absorbent; (e) recycling the regenerated absorbent into the second absorption zone; (f) condensing water vapour entrained in the second stream of carbon dioxide by cooling the second stream of carbon dioxide and transferring at least part of the heat recovered to the partially regenerated absorbent by indirect heat exchange.

  • Patent number: 8087697
    Abstract: To allow an occupant to easily wear a seat belt without twisting his or her body when the occupant sits in a seat. When a door sensor 60 detects the opening of a door, a motor is driven to wind up a seat belt 2 so as to move a belt guide 4 against biasing force of a spring 9, thereby evacuating the seat belt 2 to a rear side of a vehicle relative to a seat back 1a. When the door sensor 60 detects the closing of the door and a seat sensor 61 detects the sitting of the occupant, the motor is driven in the reverse direction to make a clutch mechanism 34 in the disconnected state so as to protrude the seat belt 2 in the forward direction of the vehicle by the biasing force of the spring 9.

  • Publication number: 20110270493
    Abstract: To produce a compact torque limiter mechanism at low cost while improving the durability of the torque limiter mechanism. An ECU 25 stops power supply to the motor 16 when it determines that a buckle switch 27 has detected engagement between a tongue and a buckle, that a seat-belt tension-control function is operating according to an output signal from an MSB-function operating-condition-signal output portion 26, and that the motor current detected by an ammeter 24 is equal to or larger than the preset current set in advance. Then, an ELR function is activated, and a seat belt 4 restrains an occupant. This prevents the torque limiter mechanism from being activated, thereby reducing the activation frequency of the torque limiter mechanism and improving the durability of the torque limiter mechanism.
