  • Patent number: 6485567
    Abstract: An external electrode forming apparatus is used to form external electrodes on the component chips. The external electrode forming apparatus comprises a component conveyer belt, a belt feeding mechanism, a component-inserting machine, a component-reversing machine, a paste-coating machine, and a component-discharging machine. For the component-inserting machine, the component-reversing machine, and the component-discharging machine, pressure pins are used to insert or move the component chips. These pressure pins have at the tip part a taper portion with a tip shape smaller than that of the component holding hole. Since the pressure pins of this type are used, the tip portions of these pressure pins may be prevented from impinging upon the opening edges of the component holding holes, and the pressure pins after the impingement may be hindered from forcibly being inserted into the component holding holes, whereby damage to the interiors of the component holding holes can be extremely diminished.

  • Patent number: 4021275
    Abstract: A gas-generating agent for inflating air bags comprises finely divided particles of a co-precipitation compound made by the following steps: (1) uniformly mixing in water to form an aqueous solution a composition comprising (a) one or a mixture of two or more alkali metal azides and/or alkaline earth metal azides and (b) an aqueous solution of a composition comprising one or a mixture of two or more nitrates or perchlorates of alkali metals or alkaline earth metals; or mixing (a) and (b) plus (c) finely divided particles of silicon dioxide; or mixing (a), (b) and (c) plus (d) fine glass powder; (2) mixing the resulting solution or suspension with a water-soluble organic solvent; and (3) separating and drying the co-precipitation compound thus obtained. The gas-generating agent will not produce toxic compounds such as sodium metal and sodium peroxide which might injure the car driver and passengers. Further, when low softening glass is added, the maximum temperature of combustion will be lowered.
