摘要:
The holding device for use in mounting a garnish on a front pillar has a pin member at the side of the garnish and a grommet member at the side of the front pillar. A leg portion of the pin member is inserted into a cylindrical portion of the grommet member. The leg portion has a first mounting engagement claw that is engaged with a first engagement portion of the cylindrical portion to hold the garnish in a given mounted state. The engagement of the first mounting engagement claw with the first engagement portion is released by means of expansion pressure of an air bag apparatus, while a second mounting engagement claw of the leg portion is brought into engagement with a second engagement portion of the cylindrical portion to prevent the pin member from coming off. At this time, a clearance is formed between the garnish and the front pillar, thereby developing an air bag into a cabin compartment of the vehicle through the clearance. By the rotation of the pin member relative to the grommet member, the engagement of the second mounting engagement claw with the second engagement portion is released, thereby allowing the pin member to be pulled out completely from the grommet member. The holding device for mounting the garnish can be re-used after the operation of the air bag.
摘要:
Elastic and ultra-lightweight hollow carbon fine particles and a method for producing such hollow carbon fine particles are to be provided. In the method, fine droplets are formed from a mixed solution containing a water soluble organic substance and lithium carbonate; composite fine particles of the water soluble organic substance and the lithium carbonate are prepared by drying the fine droplets formed from the mixed solution; and the composite fine particles are decomposed at a temperature in a range of 500° C. to 900° C.

摘要:
A method for preparing a carbon microparticle from an organic raw material having lignin as a main constituent, wherein an aqueous solution with 5% total concentration of lignin and sodium hydroxide (the proportion in mass is 1:0.5) is spray-dried to prepare a complex microparticle. This complex microparticle is heat-processed under nitrogen atmosphere at 600° C. for one hour and cooled. Thereafter, this is washed with water and further dried to prepare a hollow carbon microparticle such as those shown in FIG. 2 (b). The prepared carbon microparticle is light-weight and has an equivalent specific surface area to commercially available activated charcoal.
