  • Patent number: 11912989
    Abstract: An objective of the present invention is to provide target tissue-specific antigen-binding molecules, antigen-binding molecules whose antigen-binding activity varies depending on the concentration of an unnatural compound, libraries comprising a plurality of the antigen-binding molecules which are different from one another, pharmaceutical compositions comprising the antigen-binding molecules, methods of screening for the antigen-binding molecules, and methods for producing the antigen-binding molecules. The present inventors created antigen-binding domains whose antigen-binding activity varies depending on the concentration of a small molecule compound or antigen-binding molecules containing an antigen-binding domain, and libraries comprising a plurality of the antigen-binding domains which are different from one another or antigen-binding domains, and demonstrated that the above-noted objective could be achieved by using the libraries.

  • Patent number: 9870191
    Abstract: A display device communicates with a terminal device and includes a display unit, an extracting unit, a generating unit, and a transmitting unit. The display unit displays display data including at least one of image data and drawn data corresponding to an operation performed by a user on a screen. The extracting unit extracts a part of the display data specified by the user out of the display data displayed by the display unit. The generating unit generates image data in a form corresponding to the terminal device based on the extracted display data. The transmitting unit transmits the image data to the terminal device.

  • Patent number: 4146510
    Abstract: Flake- or sliver-like porous structures of a polymeric material heavily loaded with a finely divided inorganic substance are prepared by spurting a mixture of the polymeric and finely divided inorganic components in a solvent. The products have many fine, irregular voids. The thickness of walls forming such voids is 5.mu. or less. The products are especially useful for producing sheet-like structures therefrom by beating and/or refining them followed by general paper making procedures. The sheets, when calendered, have a high initial modulus and improved dimensional stability.

  • Patent number: 3953282
    Abstract: A polyolefin micro-flake aggregation which is easily micro-flakable from the aggregation into a plurality of irregularly shaped micro-flakes suitable for producing synthetic paper, is manufactured from a solution of 5 - 40% by weight of polyolefin such as polyethylene and polypropylene in a solvent such as hydrocarbons and chlorinated hydrocarbons in the presence of a surface active compound of at least 0.01% based on the weight of the polyolefin by spraying the solution which is at a temperature of at least 100.degree.C from a closed container into atmosphere through an orifice.A polyolefin synthetic paper is formed from a suspension of the micro-flakes in an organic liquid such as hydrocarbons and chlorinated hydrocarbons which can swell or partially dissolve the polyolefin.
