Abstract: Provided is a soft X-ray static electricity removal apparatus that has achieved an increase in the amount of ionized air discharged, with a simple structure. A soft X-ray static electricity removal apparatus (1) includes a soft X-ray generation device (90), a container (10), a soft X-ray shielding sheet (20), and an insulating layer (50). The soft X-ray generation device generates soft X-rays (92). The container (10) has an outlet (12) from which ionized air (100) that has been ionized with the soft X-rays flows out. The soft X-ray shielding sheet (20) is used at the outlet of the container and includes a first outer sheet (30), an interlayer sheet (34), and a second outer sheet (40) which are formed of a material opaque to the soft X-rays.

Abstract: The silicone rubber composition comprises, in addition to the conventional ingredients of a high-polymeric diorganopolysiloxane and a reinforcing silica filler, a specific phosphorus-containing organic compound, such as phosphinates, phosphonates and phosphates, in a limited amount. By virtue of this unique ingredient, the composition can give a cured silicone rubber product having greatly improved resistance against dynamic fatigue.

Abstract: The invention provides a novel rubber composition based on an ethylene-propylene copolymeric rubbery elastomer and curable by hot air vulcanization under atmospheric pressure giving great advantages over conventional ones vulcanizable only under pressure. The inventive rubber composition comprises, in addition to the ethylene-propylene copolymeric rubbery elastomer, an oganopolysiloxane gum having alkenyl or mercapto groups in the molecule, a reinforcing silica filler, an organic compound having at least two maleimido groups in a molecule and a curing agent which is an organic peroxide or an organic sulfur compound.
