Abstract: [Problems] A battery terminal, a battery, and a battery holder are provided which are less likely to cause a trouble that an insulated protrusion section having a configurational preventive function for improper connection is separated from a terminal surface without impairing the productivity and cost effectiveness. [Means for Solution] In battery terminals 21 and 51 on which an insulated protrusion section 31 having a configurational preventive function for improper connection is formed by discharging ultraviolet curing resin and curing the resin, the ultraviolet curing resin contains acrylate oligomer, acrylate monomer, and photopolymerization initiator, and further contains methacrylic acid added to the resin.

Abstract: A vane of a first cylinder is compressed and urged by a spring member. A vane of a second cylinder is compressed and urged corresponding to a differential pressure between an intra-casing pressure guided into a vane chamber and a suction pressure or discharge pressure guided to the cylinder chamber. A pressure shift mechanism which guides the suction pressure or discharge pressure has a branch pipe having a one end connected to a high pressure side of the refrigeration cycle, an other end connected to a suction pipe, and a first on-off valve in a midway portion, and a second on-off valve or a check valve which is provided in the suction pipe on a side upstream of a connection portion of the branch pipe and on a side downstream of an oil returning opening in an accumulator.

Abstract: An alkaline battery sealing gasket 33 made of a resin, comprises a peripheral packing portion 36 sandwiched in a pressed state between an opening end of a metal battery can 11 that contains an electricity generating element 20 and doubles as a positive electrode terminal and a negative electrode terminal 32 so as to seal the opening end with an airtight manner; and an isolation wall portion 37 for isolating a space on a back side of the negative electrode terminal from a space containing the electricity generating element, wherein in the isolation wall portion, a thinner portion 38 to break open earlier due to increases in gas pressure in the containing space to function as a safety valve is formed groove-like.
