Abstract: An ink supplying apparatus of an image forming device including an ink discharging unit to discharge ink of an ink cartridge, a needle connected to the ink discharging unit to form an ink supplying passage, a blocking unit to block the needle from being exposed to the outside, and a sealing member to seal the ink discharging unit and the blocking unit. Accordingly, the apparatus can not only block the needle from being exposed to the outside, but can also prevent an ink leakage, thereby facilitating a safer use of the image forming device to safely use.

Abstract: An optical diode which can lower the cost and save electric power is provided. An optical diode 21 of the present invention comprises a cholesteric liquid crystal (CLC) layer 2 having a selective reflection wavelength band with a left-handed helical structure, and a phase shifter 24 for changing the phase difference between two intrinsic polarized light components of left-handed circularly polarized light having a wavelength within the selective reflection wavelength band of the CLC layer 2. When left-handed circularly polarized light having a wavelength within the selective reflection wavelength band of the CLC layer 2 is incident on the phase shifter 24 in the optical diode 21, for example, the phase shifter 24 turns the left-handed circularly polarized light into right-handed circularly polarized light, this right-handed circularly polarized light can be transmitted through the CLC layer 2.

Abstract: A laser oscillation element 1 according to the invention comprises a cholesteric liquid crystal layer 2 containing cholesteric liquid crystals, a cholesteric liquid crystal layer 3 containing cholesteric liquid crystals facing the cholesteric liquid crystal layer 2, and a defect layer 4 containing a dye 5 which emits fluorescence upon optical excitation disposed between the cholesteric liquid crystal layers 2, 3. A selective reflection wavelength band in the cholesteric liquid crystals overlaps with the emission band of the fluorescence emitted by the dye 5, the helical winding directions of the cholesteric liquid crystals contained in the cholesteric liquid crystal layers 2, 3 are identical, and the transition moments of the dye 5 are aligned parallel to the surfaces of the cholesteric liquid crystal layers 2, 3. According to the laser oscillation element 1, a laser oscillation can be generated with high efficiency. Moreover, continuous wave lasing can be generated.
