  • Patent number: 11962183
    Abstract: A backup power system according to the present disclosure includes a battery, a charging circuit, power storage, a first load, a second load, and a controller that controls the charging circuit. The controller causes an input current at the charging circuit to increase at a first rate of change in response to a start signal. When the controller detects an increase in a charging voltage at the power storage up to a first voltage at which driving of the first load is possible, the controller controls the charging circuit to cause the input current at the charging circuit to increase at a second rate of change lower than the first rate of change. The charging circuit is controlled by the controller to cause the input current to increase at the second rate of change, and the charging voltage at the power storage increases up to a second voltage at which driving of both the first load and the second load is possible.

  • Publication number: 20240120618
    Abstract: [Problem] To provide a separator for a lead acid battery capable of suppressing electrolyte stratification and improving the battery reliability (prolongation of life during idling stop operation and stability of capacity detection) of a lead acid battery. [Solution] A separator for a lead acid battery, characterized in that the separator comprises a porous backweb and a plurality of ribs extending from each of both surfaces of the backweb, the rib on a surface on a side that comes into contact with a positive electrode plate is a broken rib, has a shape with two or more bending points, and is a linear broken rib that bends in opposite directions at each of two consecutive bending points or is a curved broken rib having one or more inflection points.

  • Publication number: 20230348808
    Abstract: Provided is an initial break-in lubricant composition capable of easily and economically reducing the coefficient of friction of a sliding portion. The initial break-in lubricant composition includes an organic dispersion medium and nanocarbon particles in a quantity from 0.1 to 2000 ppm by mass. The nanocarbon particles are preferably particles of one or more nanocarbon material(s) selected from the group consisting of: nanodiamonds, fullerenes, graphene oxide, nanographite, carbon nanotubes, carbon nanofilaments, onion-like carbon, diamond-like carbon, amorphous carbon, carbon black, carbon nanohorns, and carbon nanocoils.

  • Patent number: 11372138
    Abstract: An anti-reflection film (X) of the present invention includes a laminated structure including a substrate (11), a hard coat layer (12), and an anti-reflection layer (13), and a luminous reflectance of the anti-reflection layer (13) side is 2% or less. The anti-reflection layer (13) includes a surface (13a) having a coefficient of kinetic friction of 0.3 or less and a coefficient of static friction of 0.3 or less. In addition, in the anti-reflection film (X), after a rubbing test performed on the surface (13a) using steel wool #0000 as a rubbing material under conditions of a load of 200 g/cm2, a rubbing stroke length of 10 cm, and reciprocations of 1000 times, a difference of the haze value (%) after the rubbing test from the haze value (%) before the rubbing test is 0.1 or less. Such an anti-reflection film is suitable for achieving high scratch resistance together with high anti-reflective properties.

  • Publication number: 20200282712
    Abstract: An anti-reflection film (X) of the present invention includes a laminated structure including a substrate (11), a hard coat layer (12), and an anti-reflection layer (13). The anti-reflection layer (13) contains a curable resin, low-refractive-index particles, and nanodiamond particles. The anti-reflection layer (13) may further contain a fluorine-containing curable compound. Such an anti-reflection film is suitable for achieving high scratch resistance together with high anti-reflective properties.
