Abstract: A borehole cement slurry additive that is capable of suppressing the generation of free water from cement slurries in any environment, whether cold regions, mild regions, or hot regions; and a method for storing the same. The borehole cement slurry additive contains: an aqueous dispersion of silica having an average particle size of 3-200 nm as determined via dynamic light scattering; and a compound having an alcoholic hydroxyl group as a dispersion stabilizer, the compound being included in an amount of 1-30 mol per 1,000 g dispersion medium in the aqueous silica dispersion.

Abstract: Provided is an inkjet recording apparatus that performs inkjet recording on a recording medium in a recording region. The inkjet recording apparatus includes a recording head that includes an ejection port surface where an ejection port for ejecting ink is provided, is the recording head being movable within a range including the recording region and a non-recording region where the recording is not performed, a cap capable of letting the ejection port in a capping state in the non-recording region, a blade that is placed between the recording region and the cap in a moving direction of the recording head, the blade being capable of wiping the ejection port of the recording head as the recording head moves from the non-recording region to the recording region, a blade moving unit capable of moving the blade up and down, and a control unit that controls the blade moving unit.

Abstract: A vehicle includes a communicator, a road-surface abnormality determiner, and a driving controller. The communicator is configured to establish communication with a following vehicle following the vehicle driving ahead in a travel road. The road-surface abnormality determiner is configured to determine whether there is an abnormality on a road surface of the travel road, based on comparison between first driving information, serving as a reference to be used when the vehicle drives on the travel road, and second driving information detected as a result of the vehicle having actually driven. When the road-surface abnormality determiner determines that there is the abnormality, the driving controller is configured to predict whether the following vehicle is able to avoid the abnormality and to send an instruction to avoid the abnormality to the following vehicle via the communicator if the driving controller predicts that the following vehicle is able to avoid the abnormality.

Abstract: The present invention provides a heat conductive sheet that can maintain high heat conductivity and flexibility across a long period of time even in high temperature environments. The heat conductive sheet includes a (meth)acrylate polymer, a trimellitate ester plasticizer, a first antioxidant with a hindered phenol backbone, and a second antioxidant with a thioether backbone.

Abstract: A pressure sensor module capable of fixing a diaphragm to a base body without using welding is provided. A base body, a first diaphragm, a first elastic body, and a first mounting member are included. The base body has a first recess with a pressure sensor element to be installed inside, and a first receiving surface section extending outward from an opening edge of the first recess. The first diaphragm is provided facing the first receiving surface section so as to close the first recess from an inlet side and arranged separably from the base body. The first elastic body is arranged on one surface side of the first diaphragm outside the opening edge of the first recess. The first mounting member is mounted on the base body with the first diaphragm and the first elastic body pressed toward the first receiving surface section.
