Abstract: A gas-liquid separation mechanism of a reserve tank for separating gas bubbles in a coolant flowing into a reserve tank provided upstream of a liquid pump in a circulation path of the coolant includes: an inlet opening for the coolant provided at a lower portion of one of opposing side walls; an outlet opening for the coolant provided at a lower portion of the other side wall; a bubble emission port provided on an upper wall and configured to emit the gas bubbles separated from the coolant; and a partition wall extending substantially parallel to a direction from the inlet opening to the outlet opening and vertically dividing the reserve tank into first and second chambers. The partition wall includes a downstream communicating hole below an end portion proximate to the outlet opening and an upstream communicating and an upstream communicating hole above an end portion proximate to the inlet opening.

Abstract: A capacitor (2) includes a capacitor main body (4) and a base (6). The capacitor main body includes an opening sealing member (14) attached to an opening of an outer package case (10), and a terminal lead (16-1, 16-2) led out from a first insertion through hole portion (17-1, 17-2) of the opening sealing member. The base is disposed on the side of the opening sealing member of the capacitor main body, and has a second insertion through hole portion (18-1, 18-2). For example, the base includes a first protruding portion (20) surrounding the second insertion through hole portion, so that the second insertion through hole portion of the base forms an insertion through hole. The opening distance on the side of the substrate mounting face of the insertion through hole is larger than the opening distance on the side of the capacitor main body of the insertion through hole.

Abstract: A gas-liquid separation mechanism of a reserve tank for separating gas bubbles contained in a coolant flowing into a reserve tank provided in a circulation path of the coolant includes: an inlet opening for the coolant provided on a first side wall of the reserve tank; an outlet opening for the coolant provided on a second side wall opposite to the first side wall; a bubble emission port that is provided on an upper wall of the reserve tank and emits the bubbles separated from the coolant; a flow adjuster that adjusts a flow of the coolant having flowed in from the inlet opening and makes the flow rise and flow backward; and a first small wall that is provided in a vicinity of the bubble emission port and downstream of the bubble emission port in a direction where the flow flows backward, and protrudes downward from the upper wall.

Abstract: A film-shaped packaging material for a cell in which a coating layer is provided as the outermost layer instead of a substrate layer and an adhesive layer in a conventional film-shaped packaging material for a cell, thereby making it possible to produce a thinner film; wherein the packaging material is provided with exceptional moldability and insulation performance and enables lead time to be reduced. The packaging material is a laminate having at least a coating layer, a barrier layer, and a sealant layer in the stated order, the coating layer including a single- or multiple-layer configuration formed by a cured product of a resin composition containing a heat-curable resin and curing accelerator, the laminate having a piercing strength of at least 5 N, as measured in compliance with JIS 1707:1997, and the coating layer having a breakdown voltage of at least 1.0 kV, as measured in compliance with JIS C2110-1.

Abstract: A compound selected from the group consisting of 4-quinolone and derivatives thereof, homoserine lactone derivatives, and indole and derivatives thereof, and salts thereof have an action of a microbial activity improvement agent, and when it is used for a microbial activity improvement method and a biological waste treatment method, the compound or the salt thereof is useful to achieve the improvement in the treatment capacity that transcends the limit of improvement in the treatment capacity of conventional biological waste treatment facilities.

Abstract: The present invention provides a method for treating wastewater containing ammonia nitrogen, in which an entire nitrification reaction to convert ammonia nitrogen to nitrate nitrogen via nitrite nitrogen is promoted by allowing nitrifying bacteria to perform the nitrification reaction in the presence of an intermicrobial signaling molecule.

Abstract: An oil ring mechanism of a piston includes a circumferential ring groove formed in an outer peripheral surface of the piston, and a two-piece oil ring having a ring-shaped ring main body that is arranged in the ring groove and urged in the outer peripheral direction inside the ring groove by a coil expander arranged on the inner peripheral side of the oil ring main body. On lower side surface on a crankcase side of a side wall surface of the ring groove that is on the opposite side of the ring groove from an engine combustion chamber, first and second recessed portions that reduce the abutment area where a lower surface of the ring main body abuts against the lower side surface formed in a lower side abutment surface that serves as a surface for abutting against the lower surface of the ring main body.
