Abstract: A power semiconductor device includes an insulating substrate on which a first conductor layer is arranged on one surface, a first conductor that is connected to the first conductor layer via a first connecting material, and a semiconductor element that is connected to the first conductor via a first connecting material. When viewed from a direction perpendicular to an electrode surface of the semiconductor element, the first conductor includes a peripheral portion formed larger than the semiconductor element. A first recess is formed in the peripheral portion so that a thickness of the first connecting material becomes thicker than other portions.

Abstract: An organic hydride production device comprises: a cathode chamber that equips a cathode electrode for hydrogenating a substance to be hydrogenated in a catholyte with a proton to produce an organic hydride; a cathode inlet that is connected to the cathode chamber and supplies an external catholyte into the cathode chamber; an upper cathode outlet that is connected to the cathode chamber and discharges the catholyte and hydrogen gas in the cathode chamber to the outside; and a lower cathode outlet that is connected to the cathode chamber below the upper cathode outlet and discharges the catholyte and water in the cathode chamber to the outside.

Abstract: An artificial lipid bilayer membrane formation device is disclosed. It includes: an upper solution chamber whose bottom has a small hole; a lower solution chamber having a support layer; and lipid solution exclusion device. Lipid solution is applied to the small hole, and the lipid solution exclusion device excludes surplus lipid solution without changing a hydraulic pressure so that the lipid solution is in contact with the support layer, thereby forming an artificial lipid bilayer membrane on the small hole.

Abstract: An artificial lipid bilayer membrane formation device is disclosed, which includes: an upper solution chamber (first solution chamber) and a lower solution chamber (second solution chamber), both of which are filled with aqueous solution. It further includes a partition wall disposed between the upper solution chamber and the lower solution chamber so as to part the upper and lower solution chambers from each other. The partition wall has an opening, and a first lipid solution is applied to a portion around the opening, thereby forming an artificial lipid bilayer membrane on the opening. Further, in the formation device, a tubule for lipid substitution is attached to the partition wall so as to be positioned on a bulk phase of the artificial lipid bilayer membrane. A second lipid solution is added via the tubule, thereby forming an artificial lipid bilayer membrane whose lipid composition is changed.

Abstract: The current measuring device includes an upper solution chamber (3) and a lower solution chamber (8) whose bottom has a support layer (5) and measures a current flowing via an artificial lipid bilayer membrane (2) formed on a small hole (4) of the upper solution chamber (3), wherein the lower solution chamber (8) is provided below the upper solution chamber (3) by being surrounded with a bottom plate (6) and an interval keeping member (7a). An internal pressure of the lower solution chamber (8) is dropped so that the artificial lipid bilayer membrane (2) formed on the small hole (4) swells to the side of the lower solution chamber (8) so as to be thinner, and the thinner artificial lipid bilayer membrane (2) is supported by the support layer.
