Abstract: A monitoring device has a processor configured to determine whether a degree of preparedness of a driver to initiate manual control is a first degree in which manual control of a vehicle is possible, a second degree which is allowed while the vehicle is being operated by automatic control or a third degree which is not allowed while the vehicle is being operated by automatic control, based on posture information indicating a posture of the driver, acquired while the vehicle is being operated by automatic control, and a notification control unit that provides a predetermined notification to increase the degree of preparedness of the driver to initiate manual control, via a notification unit, when it has been determined that the degree of preparedness to initiate manual control is the third degree.

Abstract: A cleaning apparatus includes: a main body; wheels movably supporting the main body; a main brush rotatably supported in (by) the main body and configured to brush up refuse on a surface-to-be-cleaned; a first dust unit, which is detachable from the main body and into which refuse brushed up by the main brush is dispatched; a second dust unit, which is detachable from the main body and into which refuse brushed up by the main brush is dispatched; and a dust-collecting assembly comprising: a dust-collecting fan; a dust-collecting motor, which rotates the dust-collecting fan; and an outflow port, from which gas that has passed through the dust-collecting fan flows out; the dust-collecting assembly being configured to suction dust swept up by the main brush. The first dust unit and the second dust unity respectively have a first passageway and a second passageway, into which gas from the outflow port flows.

Abstract: A support body included in the solid electrolyte layer of the lithium ion secondary battery is constituted by a non-woven fabric having an air permeability in a range of 1 to 50 L/cm2/min, a thickness in a range of 5 to 30 ?m, and a density in a range of 0.15 to 0.45 g/cm3.

Abstract: A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

Abstract: A cleaning apparatus may include: a main-body unit; and first and second dust units, which are alternately attachable to and detachable from the main-body unit. The main-body unit may include: one or more cleaning tools, which brush(es) up waste on a work surface; a main body rotatably supporting the cleaning tool(s); and one or more wheels rotatably supported by the main body and configured such that the cleaning apparatus is movable along the work surface via the one or more wheels. The first dust unit may include: a first container, which is detachable from the main body and is capable of collecting the waste brushed up by the cleaning tool(s). The second dust unit may include: an adapter, which is detachable from the main body; and a second container, which is detachable from the adapter and is capable of collecting the waste brushed up by the cleaning tool(s).

Abstract: A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

Abstract: A cleaning machine may include: a first brush including a first brush shaft and a first brush body held by the first brush shaft; a second brush including a second brush shaft and a second brush body held on the second brush shaft; a first brush attaching member having a first shape, wherein one end of the first brush shaft is detachably attached to the first brush attaching member; and a second brush attaching member having a second shape, wherein one end of the second brush shaft is detachably attached to the second brush attaching member. The one end of the first brush shaft may have a first corresponding shape that corresponds to the first shape. The one end of the second brush shaft may have a second corresponding shape that corresponds to the second shape. Other end of the first brush shaft may have the second corresponding shape.

Abstract: A cleaning machine may include: a drive shaft; a rotation transmitting mechanism configured to transmit rotation of the drive shaft; a brush attaching member configured to rotate about a rotation axis; a clutch mechanism coupling the rotation transmitting mechanism with the brush attaching member; a brush attached to the brush attaching member; and a brush moving mechanism configured to move the brush attaching member between an adjacent position adjacent to a working plane and a distant position distanced from the working plane. The clutch mechanism may be configured to transmit the rotation from the rotation transmitting mechanism to the brush attaching member when the brush attaching member is at the adjacent position and cut off transmission of the rotation from the rotation transmitting mechanism to the brush attaching member when the brush attaching member is at the distant position.

Abstract: A separator for alkaline batteries, which exhibits excellent strength, dimensional stability and chemical stability in an electrolyte solution, while having high shielding properties, high liquid holding properties and low resistance. A separator for alkaline batteries, which is used for the purpose of separating a positive electrode active material and a negative electrode active material from each other, and holding an electrolyte solution, and which is obtained by stacking and integrating a fiber layer A that has a density of 0.52-0.62 g/cm3 and a thickness of 25-35 ?m and a fiber layer B that has a density of 0.40-0.50 g/cm3 and a thickness of 25-35 ?m, so that the entirety of the separator has a density of 0.45-0.57 g/cm3 and a thickness of 50-70 ?m.
