    摘要: An image duplicating apparatus including an optical exposure lamp by which a document bearing images is to be scanned by illumination with light, a photosensitive drum on which the images on the document are to be reproduced, a slot through which the light reflected from the document is to be passed toward the drum, and an automatic exposure control system which detects the density of the images on the document from the intensity of the light passed through the slot. The automatic exposure control system produces a first signal representative of the detected image density and produces in response to the first signal a second signal indicative of whether or not the illumination value is adjustable in a real-time automatic exposure control mode. The exposure lamp is responsive to the first and second signals such that, when the second signal indicates that the illumination value is adjustable in the real-time automatic exposure control mode, the exposure lamp is activated to illuminate the document with an illumination value variable with the first signal and, when the second signal indicates that the illumination value is not adjustable in the real-time automatic exposure control mode, the exposure lamp preliminarily scans the document for producing the first signal and determining the illumination value on the basis of the first signal whereupon the exposure lamp is activated to illuminate the document with the illumination value thus determined.

    摘要: The present invention provides a method for producing silicone rubber moldings composed of a uniform, smooth and hard exterior layer and a relatively soft interior portion. In accordance with this method the surfaces of the mold cavity are coated with an organohydrogenpolysiloxane containing at least two silicon-bonded hydrogen atoms before the curable organosiloxane used to form the interior portion of the molding is injected into the mold cavity and cured.
