Abstract: To solve the problems that caffeine has a useful physiological effect, but on the other hand, it is not suitable for a child or a pregnant woman who is irritable thereto, so a caffeine concentration is controlled, and conventionally, an agent and an adsorbent are used, so the complexness of operation and the generation of waste become problems.SOLUTION: Caffeine is separated by: introducing a caffeine-containing liquid into a hydrogen ion generating chamber of a bipolar membrane electrodialysis device in which a cation exchange membrane is arranged between two bipolar membranes; coordinating hydrogen ion in caffeine to make caffeine cation; and passing the cation exchange membrane. The caffeine cation passing through the cation exchange membrane is returned to caffeine and water and concentrated by hydroxide ion generated by the other bipolar membrane. Thus, caffeine is separated by using only electricity while leaving the other useful components.SELECTED DRAWING: Figure 3

Title: Soundproof panel
Inventor: ICHIHARA KOJI
IPC: E01F8/00
Filed: 2019-03-07
Abstract: To provide a soundproof panel which provides a same performance as so-called unified type even without using a sound absorbing material.SOLUTION: Blades 3a and 3b are attached to a back plate of an accommodating housing 2 of a soundproof panel at predetermined intervals (blade pitch). A sound wave S of noise coming from an X1 side of the soundproof panel reaches an arbitrary reflector. The sound wave S that reaches an arbitrary reflector is reflected thereon, and is further reflected by an adjacent upper reflector. After that, repeating such reflection and reaching a recess formed by the two adjacent reflectors, the sound wave returns in the exit direction on the contrary. At that time, the sound wave advances while colliding (interfering) with the sound wave S coming into the recess, and is attenuated according to phase difference with the sound wave S coming into the recess. A distance Dh is set optimally according to the assumed noise, so that the phase difference is maximized and a sound pressure level of the sound wave S outgoing from the recess is minimized. As a result, the noise toward an X2 side is relieved.SELECTED DRAWING: Figure 5
