摘要： PROBLEM TO BE SOLVED: To provide a foldable bed allowing manual labor to be extremely reduced and capable of being simply folded up and reclined by a single, electric expansion and contraction arm.
SOLUTION: The foldable bed 1 can be simply folded by the expansion and contraction arm 30 activated by an electric drive mechanism, allowing a folding work to be simply implemented without the manual labor or to be easily implemented even by a person with relatively less muscle power. Not only folding up the bed but reclining the same by the single arm 30 requires no additional body as a mechanism for turning a reclining frame.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that in the manufacture of an optical functional element comprising a ferroelectric single crystal, a pyroelectric effect occurs in a once-produced polarization reversal part of a several microns in size during the heat treatment to eliminate distortion, and this results in fracture in the crystal or in changes in the size and the position of inversed polarization although the changes are small. SOLUTION: The optical functional element is produced by forming a polarization reversal structure at a temperature equal to or lower than the Curie temperature in a part of a ferroelectric single crystal substrate by using an electron beam scanning and irradiation method or a voltage application method, and the element controls the light passing through the above polarization reversal part. The optical functional element shows ≤2% propagation loss of the light passing through the polarization reversal part just after the polarization reversal structure is formed. As for the single substrate for the above element, a LiNbO 3 crystal having the composition with a constant molar ratio of Li/Nb or a nearly constant molar ratio in the range from 0.95 to 1.01 is used without heat treatment or by subjecting to the heat treating at ≤100°C.
