摘要:
A crosslinking agent for water-absorbing resins which comprises (A) at least one halohydrin compound selected between (A1) a first halohydrin compound having per molecule at least two halohydrin groups (D) represented by the general formula (I), wherein R1 represents hydrogen or alkyl and X represents chlorine or bromine and (A2) a second halohydrin compound having per molecule at least two halohydrin groups (D) represented by the formula (I) and having per molecule at least one ammonium group (M) represented by the general formula (II), wherein R2's each independently represents a C1-4 hydrocarbon group or benzyl.
摘要:
A polysilane having excellent functionalities (e.g., solubility in a solvent and reactivity) is obtained by introducing a structural unit of the following formula (1) to a polysilane through a reaction of a dihalosilane having a Si—H bond and adding a hydrosilylatable compound (e.g., a compound having a carbon-carbon unsaturated bond) to the Si—H bond, wherein R1 represents a hydrogen atom, an organic group, or a silyl group; and “n” denotes an integer of not less than 1.

This prevents biting and miniaturizes an entire mechanism. There is provided a lens driver including: a driver having a frame that holds a lens and a bearing for receiving a guiding axis to move the lens in an optical axis direction, a lead screw in which a screw to which a nut is screwed is formed, and a stepping motor for rotating the lead screw; an arm extended from the frame, in such a way a tip being next to the nut, and moving the frame by movement of the nut; a spring for pushing an arm tip towards the nut; and an idle rotation section placed on only side where the arm is placed for the nut at a lead screw end of the driver, and has an axis diameter disabling the nut to be screwed. Also there is provided an image capture apparatus having the lens driver.
