    摘要: A liquid crystal device is formed by a pair of substrates each having thereon electrodes, and a liquid crystal disposed between the substrates so as to be movable along surfaces of the substrates. The liquid crystal is disposed over regions extending between the surfaces of the substrates including an effective optical modulation region, a first peripheral region outside the effective optical modulation region and a second peripheral region formed along a part or an entirety of outer periphery of the first peripheral region. The liquid crystal is disposed to have a higher liquid crystal molecular pretilt angle in the first peripheral region than in the effective optical modulation region. The liquid crystal is disposed in a random alignment state free from uniaxial alignment characteristic or in a layer structure in the second peripheral region. As a result, the liquid crystal molecular movement along the extension of substrates is suppressed in the effective optical modulation region and in the second peripheral region and relatively allowed in the first peripheral region, so that the impurities in the liquid crystal are confined in the second peripheral region while avoiding the liquid crystal thickness irregularity.

    摘要: Disclosed is a glass molding process using an apparatus for manufacturing a glass preform into a glass molded product. In the process a mold is prepared for pressing the glass preform. The mold consists of a pair of molds having a cavity surface for forming the glass molded product, and a frame mold which is movable against the pair of molds and incorporates a heating source. A next step in the process involves introducing the glass preform, where the pair of molds are opened and the glass preform is placed on the cavity surface. The glass preform then undergoes heating, where the glass preform is moved so as to come near the heating source of the frame mold by closing the mold, thereby heating the glass preform. The glass preform is then pressed by moving the mold to mold a shape of a glass molded product. The resulting glass molded product is then separated from the heating source by moving the frame mold and taken out by opening the mold.

    摘要: A method is provided for molding high-precision glass products where a piece of glass is heated at least in its surface portion and pressed between a pair of molds. Relative movement of the molds toward each other during the pressing is caused to follow change in dimension of a heated interval control member provided between the pair of molds, the interval control member having a coefficient of thermal expansion which is equal to or larger than that of the glass piece and therefore being capable of thermal contraction in the pressing direction by an amount which is substantially equivalent to or larger than that of the glass piece in the pressing direction due to cooling of the glass piece, and the change in dimension of the interval control member being caused by thermal contraction due to cooling thereof.

    摘要: A liquid crystal device is constituted by a pair of oppositely disposed substrates having opposing inner surfaces and opposing electrodes thereon, and a chiral smectic liquid crystal assuming two stable states disposed between the opposing electrodes. The opposing inner surfaces of the pair of substrates have been subjected to an aligning treatment such that the liquid crystal placed in one of the two stable states moves under application of an electric field in a direction identical to one in which the liquid crystal placed in the other of the two stable states moves under the application of the electric field. The liquid crystal device has an effective optical modulation region and a peripheral region outside the effective optical modulation region, wherein the effective optical modulation region and the photosensitive member have been subjected to different aligning treatments. In the liquid crystal device thus constituted, a liquid crystal movement liable to cause yellowing or fluctuation in drive parameters otherwise is effectively compensated by a liquid crystal movement in the peripheral region.
