  • Patent number: 9927349
    Abstract: In a method of producing a device in which an element structure is provided on a substrate including a through wiring, a through hole is formed so as to extend from a first surface of the substrate to a second surface of the substrate disposed on an opposite side of the substrate to the first surface, the through wiring is formed by filling the through hole with an electrically conductive material, and the element structure is formed on a first surface side. In the step of forming the through hole, a degree of surface irregularities of an inner wall of the through hole is larger on the first surface side than on a second surface side.

  • Patent number: 9928616
    Abstract: A data conversion server reduces a data amount of a path that constitutes drawing data. The data conversion server adds information used to adjust a scale of the drawing data to the drawing data, wherein the information is obtained based on a length of the path before the data amount is reduced. For example, in a case of data in the SVG format, path length information before the data amount is reduced is set to an attribute (pathLength) as the information used to adjust the scale.

  • Patent number: 9930203
    Abstract: An information processing apparatus is configured in the following manner. When a client is connected to a server, the client transmits all of setting information that the client handles as a synchronization target to the server. The server returns an error response to prohibit synchronization in response to transmission of a setting item that the server does not handle as the synchronization target among the setting information transmitted from the client. After that, the client apparatus does not notify the server of a content of an update with respect to the setting information of the setting item to which the error response is returned when the client is connected to the server.

  • Patent number: 9929067
    Abstract: A method of manufacturing a ceramic package is provided. An electrically conductive paste is applied to an inside of the first hole and an inside of the second hole of a ceramic green sheet. A ceramic member including first and second electrically conductive members is formed by burning the ceramic green sheet. The ceramic member is divided so as to divide each of the first and second electrically conductive members. A distance between first and second connecting portions is smaller than each of a length of the first connecting portion in a first direction and a length of the second connecting portion in a second direction. The length of the first connecting portion in the first direction is larger than a length of the first connecting portion in a third direction. The length of the second connecting portion has a similar relation.

  • Patent number: 9930306
    Abstract: An image processing apparatus includes a detection unit, a size changing unit, and a determining unit. The detection unit detects, from a first captured image obtained by capturing a projection image projected by a projection unit, a vertex of the projection image. The size changing unit reduces a size of the projection image in response to the detection unit not detecting a predetermined number of vertexes of the projection image from the first captured image. The determining unit determines a distortion correction parameter to be used for correcting a distortion of a projection image projected by the projection unit, in accordance with a detection result of vertexes by the detection unit for a second captured image obtained by capturing the size-reduced projection image in a case where the detection unit detects the predetermined number of vertexes of the size-reduced projection image from the second captured image.
