    摘要： A flame retardant epoxy resin composition which can improve heat resistance and exhibit an excellent adhesion strength and insulation reliability when applied to a printed circuit board or to a multilayered interconnection laminate is provided, and a prepreg and a metal foil clad laminate using the same composition are manufactured. This flame retardant epoxy resin composition consists of: (a) an epoxy resin containing a glicidylether compound which is a condensate of bisphenol A or bisphenol F with formaldehyde; (b) a condensate of bisphenol A with formaldehyde; (c) haloganated bisphenol A as a flame retardant agent; and (d) a hardening accelerator, wherein the haloganated bisphenol A is contained in 45 weight % or less of a total solid resin weight. A metal foil clad laminate is provided using this composition as a varnish, impregnating the same into a base material to obtain the prepreg, laminating the prepreg, depositing a metal foil on one or both surfaces thereof, and heating under pressure.

    摘要： An automatic document conveying device is applied to an image processor that has a transparent plate. The automatic document conveying device can convey a continuous document that has folding lines extending in the direction of width at stated intervals in the conveying direction and feed holes formed in both side edges thereof at stated intervals in the conveying direction. The automatic document conveying device includes a continuous document placing device on which will be placed the continuous document in a condition where it is folded along the folding lines, a conveying devices for conveying the continuous document passing on the transparent plate of the image processor, and a continuous document receiving device for receiving the continuous document conveyed passing on the transparent plate. The conveying device conveys the continuous, document from the continuous document placing device passing on the transparent plate while unfolding it along the folding lines and further conveys it onto the continuous document receiving device while again folding it along the folding lines. The conveying device includes a conveyer belt mechanism, pin tractor mechanisms, and a conveyance control device that controls the operations of these conveyer belt mechanism and pin tractor mechanisms.
