摘要： In a variable-shape mirror of which the shape of the mirror surface can be varied, a mirror portion is bonded only to a fixed portion and not to a piezoelectric element. When the piezoelectric element is not operating, the mirror portion, receiving a predetermined force from the piezoelectric element, makes contact with the piezoelectric element. When the piezoelectric element contracts, the mirror portion tends to restore its original shape by its counterforce. Thus, even when the piezoelectric element contracts, the contact between the mirror portion and the piezoelectric element is held, and hence the electric conduction to the piezoelectric element is maintained.

摘要： The invention provides a novel planographic printing plate suitable for dry planographic printing without supply of dampening water and a method for the preparation thereof. The inventive printing plate has, on one surface of a base plate, a layer of an organopolysiloxane composed of the areas where fresh surface of the organopolysiloxane is exposed bare as the ink-repellent non-image areas and the areas where the surface of the organopolysiloxane layer has been subjected to the treatment with low temperature plasma to be oleophilic or ink-receptive as the image areas of the printing plate. According to the inventive method, the pattern-wise exposure of the organopolysiloxane layer to the plasma atmosphere is performed by first providing a pattern-wise layer of a plasma resistant protective resist layer on the organopolysiloxane layer followed by the plasma treatment and removal of the resist layer. In an improved embodiment of the invention, a layer of an abrasion-resistant ink-receptive material is provided on the organopolysiloxane layer in the plasma-treated areas so that the durability of the printing plate is remarkably improved. Further, incorporation of a metachromatic substance susceptible to plasma treatment, e.g. a dye subject to color change by the plasma treatment, in the organopolysiloxane or in an undercoating primer layer facilitates determination of the end point of the plasma treatment.

摘要： Novel benzophenone derivatives represented by the general formula R.sub.m.sup.1 --C.sub.6 H.sub.5-m --CO--C.sub.6 H.sub.5-n --R.sub.n.sup.2 where R.sup.1 is a halogen atom, a monovalent C.sub.1-10 hydrocarbon, alkoxy, thioalkoxy, amino, or dialkylamino group, R.sup.2 is an unsubstituted or organosiloxy-substituted organosilyl group, and m and n are each integers from 1 to 5. The benzophenone derivatives are useful as photosensitizers for making photo-curable compositions by blending with photo polymerizable resins, especially photopolymerizable organosilicon resins. Such photo-curable organosilicon resin compositions are further useful for making dry-planographic printing plates comprising non-image areas formed from the polymerized and cured layers of the composition.
