  • Patent number: 10308670
    Abstract: The purpose of the present invention is to provide silanol compounds that can be used as raw materials of siloxane compounds and the like, and a composition of the silanol compounds, as well as to provide a production method that makes it possible to produce silanol compounds at excellent yield. A composition comprising 5 mass % to 100 mass % of a silanol compound represented by Formulas (A) to (C) can be prepared by devising to produce silanol compounds under water-free conditions, to produce silanol compounds in a solvent having the effect of suppressing the condensation of silanol compounds, and to perform other such processes, the composition being able to be used as a raw material or the like of siloxane compounds because the silanol compounds can be stably present in the resulting composition.

  • Publication number: 20190071269
    Abstract: A feeding device comprises a suction feeding unit having a belt for feeding a sheet in a suction state and a belt driving unit, a sheet detection sensor, and a control unit. The control unit controls the belt drive unit so as to feed the sheet in a feeding direction at a first speed. If the sheet does not arrive at the sheet detection sensor, the control unit controls the belt drive unit so as to execute a low-speed feeding ox moving the belt in the feeding direction at a second speed lower than the first speed or so as to execute a reverse feeding of moving the belt in a reverse feeding direction opposite to the feeding direction.

  • Publication number: 20180067132
    Abstract: Disclosed is a method for assisting the detection of Alzheimer's disease or mild cognitive impairment, the method for assisting the highly accurate detection of Alzheimer's disease or mild cognitive impairment. In the method for assisting the detection of Alzheimer's disease or mild cognitive impairment, the amount of at least one miRNA selected from miR-122, miR-144, let-7f, miR-128-3p and miR-107 contained in a test sample separated from a living body is used as an indicator. A larger amount of miR-122 than that in a healthy individual, or a smaller amount of at least one miRNA selected from miR-144, let-7f, miR-128-3p and miR-107 than that in a healthy individual is indicative that the living body is more likely to have developed Alzheimer's disease or mild cognitive impairment.

  • Patent number: 4158401
    Abstract: A device for controlling a propagation direction of noise, which is preferably associated with a sound insulating wall to significantly improve its sound reducing effect of alleviating noise emitted from a noise source such as a railroad, highway and the like on which an electric car and automobiles run. The device comprises a hollow structural body composed of a plurality of elongated vertical hollow passages arranged at right angles to a substrate and spaced apart from each other by means of partition walls. The upper noise inlet side surface of the hollow passages face a propagation direction of noise emitted from the noise source and serve to refract and lag in phase the noise passed therethrough, thereby producing a sound reducing region located intermediate between a direct sound propagation and the refracted sound propagation. In one embodiment, a pair of hollow structural bodies are arranged in opposition to each other to form an arch type device.

  • Patent number: 4156476
    Abstract: A noise control device which produces behind it an enlarged sound reducing region is disclosed. The device comprises a hollow structural body composed of a plurality of elongate hollow passages which are different in length and constructed such that the passage length is made the longest at a substantially center part in a vertical direction and is made gradually shorter from the center part toward upper and lower edges of the hollow structural body. The upper and lower edges allow direct propagation sound emitted from a noise source to pass thereover and therethrough.
