Abstract: A webbing take-up device which, when a webbing belt is pulled out, can reduce the rewind urging force applied to the vehicle occupant by the belt. The take-up device includes a spool 20 for winding a webbing belt, a take-up shaft that is connected to the spool, a shaft member connected to the take-up shaft via adapters 30, 44, a torsion coil spring 56 connected between a ratchet wheel 52 and adapter 44, another torsion coil spring 60 connected between the adapters 30, 44 and a spiral spring 48 connected to the shaft member. When the belt is pulled out and secured over an occupant, a plunger 70 engages ratchet wheel 52, and torsion coil spring 56 is wound tighter on the adapter 44. The resultant frictional force and urging force of the torsion coil spring 60 is greater than the urging force of the spiral spring 48. Thus, slack is present in the torsion coil spring 60, and the adapter 30 rotates relatively to the adapter 44.

Abstract: Conventional container is composed of a single resin layer. In case of applying heat externally to the container, the heat is hardly conducted. According to the present invention, a container with high thermal conductivity can be provided. A portion contacted with a sample is composed of a resin alone, a portion contacted with a sample container supporter is composed of two portions of a flexible resin mixed a filler having high thermal conductivity therein and a resin and a filler having high thermal conductivity. The present invention is applicable to biotechnological, chemical, medical and engineering fields to develop new uses and applications.

Abstract: A webbing winding device having a pre-tensioner for tensioning a webbing for restraining a passenger in a passenger restraining direction in an emergency deceleration of a vehicle, comprising a winding shaft to which an end of the webbing is fixed and a gear train mechanism comprising a plurality of gears arranged in such a manner that adjacent gears mesh with each other, wherein a driving gear which receives an external driving force when the pre-tensioner is actuated is driven from a starting end position to a terminating end, position which are set in advance, so as to rotate the winding shaft in a direction for retracting the webbing, and when a driving of the driving gear is completed, at least a pair of adjacent gears are separated so as to enable the winding shaft to be rotated in the direction for retracting the webbing by inertial force.

Abstract: A webbing take-up device which, when a webbing belt is pulled out, can reduce urging force applied in a direction of taking up the webbing belt. When a spiral spring 48 rotates an adapter 44 with a plunger 70 engages a ratchet wheel 52, a torsion coil spring 56 is wound tighter on the adapter 44. A resultant force of frictional force at this time and urging force of the torsion coil spring 60 which is fit tightly to adapters 30, 44 is greater than urging force of the spiral spring 48. Thus, the torsion coil spring 60 is slack, and the adapter 30 rotates relatively to the adapter 44. In this way, until the torsion coil spring 60 is fit tightly to the adapters 30, 44, even if the webbing belt 26 is pulled out, urging force of the spiral spring 48 is not applied to a spool 20.

Abstract: Upon a sudden deceleration of a vehicle, if an inertial body moves a predetermined amount against the urging force of a return spring, the trigger means will be released from engagement with the firing pin. Under the urging force of a spring, the firing pin is released from engagement with the trigger means, strikes and ignites a detonator so as to activate the actuator. The trigger means will not move until the inertial body has moved by the predetermined amount. Only after the inertial body has moved the predetermined amount, will the trigger means start to move suddenly and quickly. Therefore, friction at the time the inertial body engages the trigger means is kept constant. The stable operation of the sensor is thereby assured.
