Abstract: An electrolytic capacitor includes an electrode foil and a lead member connected to the electrode foil. The electrode foil has a first principal surface and a second principal surface opposite to the first principal surface. The electrode foil and the lead member are connected by a caulking part in an overlapping part in which the first principal surface of the electrode foil and the lead member overlap each other. The caulking part has a through-hole penetrating the electrode foil and the lead member. The electrode foil in the caulking part includes a first folded part that is folded back at a peripheral edge portion of the through-hole to be disposed on the second principal surface. The lead member in the caulking part includes (i) a penetrating part that penetrates the electrode foil and (ii) a second folded part that is folded back at an end portion of the penetrating part to be disposed on the second principal surface. The penetrating part includes an inner wall of the through-hole.

Abstract: A sample support includes: a substrate having a plurality of through-holes opening on a first surface and on a second surface; a first member having a plurality of first openings and disposed on the first surface; a second member having a plurality of second openings and disposed on the second surface, and; a bonding member disposed between the first member and the second member; and a conductive layer integrally provided on a region of the second surface corresponding to each of the plurality of second openings. The plurality of through-holes include a plurality of first through-holes located between each of the plurality of first openings and each of the plurality of second openings, and a plurality of second through-holes located between the first member and the second member. Each of the plurality of second openings communicate with each of the plurality of first openings through the plurality of first through-holes.

Abstract: A sample support body for ionization of a sample, including: a substrate having a first surface, a second surface on a side opposite to the first surface, and a plurality of through-holes opening on each of the first surface and the second surface; a conductive layer provided on the first surface; and a matrix crystal layer provided on at least one of the conductive layer and the second surface, in which the matrix crystal layer is formed of a plurality of matrix crystal grains so as to include a gap communicating the plurality of through-holes with an outside.

Abstract: In a pressure vessel which is formed by blow molding a plastic liner with a mouth member fitted on a blow pin, a rotational torque is prevented from being applied between the mouth member and the blow pin when removing the blow pin. A parison is placed around the mouth member which is fitted on the blow pin, and is blow molded with a die assembly placed around the parison so that a vessel shaped plastic liner is formed. An engagement structure which is provided between the mouth member of the pressure vessel and the blow pin includes a ball moveably received in a radial through hole of the peripheral wall of the blow pin, and a release groove formed on an inner circumferential surface of the mouth member and having a prescribed depth. When the blow pin is introduced into the mouth member until the ball and the release groove oppose each other, the ball moves radially outward and becomes partly received by the release groove to engage the mouth member with the blow pin.

Abstract: Provided is a grill shutter configured to selectively open and close an external air intake opening formed in a front part of a vehicle body. The grill shutter includes: a frame surrounding the external air intake opening; a plurality of blades rotatably supported by the frame and driven to rotate between a closed position for closing the external air intake opening and an open position for revealing the external air intake opening; a drive unit for rotationally driving the blades; and a power transmission mechanism transmitting a drive force of the drive unit to the blades, the power transmission mechanism configured to cause the blades to start an opening movement one after another with a predetermined time lag between successive opening movements.
