Patent number: 11962183Abstract: 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.Type: GrantFiled: June 3, 2020Date of Patent: April 16, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kazuo Takenaka, Takashi Higashide, Katsunori Atago, Youichi Kageyama, Hisao Hiragi, Yugo Setsu, Hiroki Nishinaka, Shinichi Tanida

Publication number: 20240120618Abstract: [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.Type: ApplicationFiled: December 28, 2021Publication date: April 11, 2024Inventors: Hiroki Kageyama, Takashi Shidomi, Masaki Onishi

Patent number: 11372138Abstract: 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.Type: GrantFiled: August 6, 2018Date of Patent: June 28, 2022Assignee: DAICEL CORPORATIONInventors: Takahiro Sakakibara, Kouichi Umemoto, Ryouta Kojima, Hiroki Kageyama
