摘要:
There is disclosed an optical device capable of deforming a member connecting a pair of optically transparent parallel-faced flat plates, thus varying the mutual angle of the paired flat plates and obtaining a predetermined optical performance on the passing light beam. The connecting member is formed by connecting plural elastic members so as to form Y-shaped or modified Y-shaped cross section in a number at least equal to zero. The connecting member is formed, in at least a part of the elastic members, by one-layered or plural-layered polymer films.

摘要:
In an optical element, an optically transparent substance is sandwiched between transparent paired plate-shaped elements by utilizing a connection member capable of deforming, and the angle formed by the paired plate-shaped elements is caused to vary by a force applied thereto from the outside, so that a predetermined optical characteristic for the passing light rays is obtained. The connection member is constructed from a high-molecular material capable of molding.
摘要:
Provided is a polychloroprene latex extremely superior in adhesion properties.According to the present invention, chloroprene or a mixture of chloroprene and a monomer copolymerizable with chloroprene is polymerized in the presence of a surfactant in an aqueous medium, in which the surfactant's concentration is lower than its critical micelle concentration (CMC) to obtain a polychloroprene latex. The polychloroprene latex produced according to the present invention is extremely superior in adhesion properties and others and give a smaller amount of deposits during production.
摘要:
A lever mechanism for connector fitting 1 includes a hold part 2 for holding a connector housing 4, and a handle part 3. When the handle part 3 is rotated and the connector housing 4 is thereby inserted into the connector housing 5, an engaging projection 24 is caused to retreat from the inner surface of a side plate 21 toward the connector housing 4, thereby removing the holding of the connector housing 4 by the hold part 2.
