摘要:
Embodiments of the present invention provide a component-built-in wiring board capable of preventing a defect, such as a crack, resulting from stress concentration at a corner, when a component is accommodated in a housing portion of a core material with resin filler filled therebetween. The component-built-in wiring board can include a component accommodated in the housing portion of a core material, and a laminate portion in which insulating layers and conductor layers are laminated alternately on the core material. A gap between the housing portion of the core material and the component can be filled with a resin filler. In an inner circumferential portion of the housing portion of the core material a first straight chamfered portion is formed at each corner of a rectangle, and in an outer circumferential portion of the component a second straight chamfered portion is formed at each corner of a rectangle.

Navigation apparatuses, methods, and programs set a reference point at an intersection and set a region extending ahead of the vehicle in a direction in which the vehicle enters the intersection, the region including the reference point. Then, the apparatuses, methods, and programs obtain 3D map data of the region, generate a 3D movie which has a predetermined viewpoint on the basis of the obtained 3D map data, and display the generated 3D movie.

A method of producing a multilayer wiring substrate is disclosed. The multilayer wiring substrate is free from a core substrate and includes a build up layer which includes an insulator layer and a wiring layer. One of a first main surface and a second main surface of the build up layer is formed with a metal supporting frame body. The method includes the steps of: forming a first insulator layer on a first main surface of a metal supporting plate, where the first insulator layer is included in the insulator layer and becomes a first resist layer which is positioned on the first main surface's side of the build up layer, and forming a first metal pad layer in a given position on a first main surface of the first insulator layer, where the first metal pad layer is included in the wiring layer and becomes a metal pad layer.

A method for manufacturing a wiring board includes a core substrate preparation step, a component preparation step, an accommodation step, a resin layer formation step, a fixing step, an insulation layer and a surface activation step. In the accommodation step, a component is held in an accommodation hole of a core substrate. In the resin layer formation step, a gap between an inner wall surface of the accommodation hole and a side surface of the component is filled with a resin layer. In the fixing step, the resin layer is hardened. In the insulation layer formation step, a resin insulation layer is formed on a second major surface and a second component major surface. In the surface activation step, a surface of the resin layer is activated by means of plasma treatment, after the fixing step but before the insulation layer formation step.

Navigation apparatuses, methods, and programs set a first reference point on a driving route, set a second reference point on the driving route, the second reference point being prior to the first reference point along the driving route, and set a third reference point on the driving route, the third reference point being after the first reference point along the driving route. The apparatuses, methods, and programs set a triangular area having vertices corresponding to the first reference point, the second reference point, and the third reference point and obtain three-dimensional map data around the triangular area. The apparatuses, methods, and programs set a predetermined translucent ratio to a structure included in the triangular area out of the obtained three-dimensional map data. The apparatuses, methods, and programs generate a moving three-dimensional image which displays the driving route overlapped with the structure set with the predetermined translucent ratio and display the generated three-dimensional motion-image.
