Abstract: With reference to a message table associating a plurality of messages to be notified to a driver of a vehicle with a first condition, a second condition, last notification time of the message, and renotification requirement, a notification device selects messages associated with an identified first condition corresponding to a situation of surroundings of a vehicle or a state of a driver, selects, from among the messages associated with the identified first condition, messages associated with an identified second condition corresponding to a state of the driver, specifies, from among the messages associated with the identified second condition, a message without a record of last notification time or a message with a record of last notification time and with a renotification requirement requiring a renotification, and notifies the specified message to the driver through an output device.

Abstract: A notification device detecting a predetermined action of a driver of a vehicle in which travel is controlled by an autonomous driving system from a driver image including a face region representing a face of the driver and outputting a confidence rate indicating a certainty in the detection, specifying a message for inhibiting a control ending action which possibly follows the detected action and corresponds to an ending condition of control by the autonomous driving system, and notifying the driver of the specified message through an output device when an effectiveness level is higher than a predetermined notification threshold, the effectiveness level calculated by multiplying the confidence rate by a first probability of the control ending action being inhibited when notifying the driver of the specified message or by a second probability of the control ending action being performed when not notifying the driver of the specified message.

Abstract: A position displacing device has a processor configured to set a recommendation range of the seat position, capable of displacing the seat position to a manual control position representing the seat position when a driver is operating a vehicle manually within a predetermined time, based on the manual control position, set an intermediate position between the manual control position and an automatic control position set within the recommendation range, and determine whether a level to which the driver is contributing to driving is equal to or below a predetermined reference threshold based on information that describes physical condition of the driver, wherein the seat position is displaced from the automatic control position to the intermediate position when the seat position is at the automatic control position and it is determined that the level to which the driver is contributing to driving is equal to or below the reference threshold.

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.
