Abstract: An advantage of the present invention is to suppress moisture infiltrating from a pad electrode portion from spreading over the surface of a wiring pattern and improve the reliability of a packaging board. The wiring pattern of the packaging board is formed on an insulating substrate and includes a wiring region, an electrode region (pad electrode) connected with a semiconductor device, and a boundary region provided between the wiring region and the electrode region. A gold plating layer is provided on the surface of the electrode region of the wiring pattern. The top surface of the boundary region of the wiring pattern is so formed as to be dented from the top surface of the wiring region of the wiring pattern, and there is provided a stepped portion in the boundary region.
Abstract: Provided is a sealed battery that can offer excellent battery performances by having its electrode terminal and a current collector securely welded to each other, and its manufacturing method. The sealed battery is formed by hermetically sealing a casing storing an electrode assembly and the current collector, wherein: the electrode assembly formed by layering positive and negative electrode plates with a separator sandwiched therebetween is electrically connected to the current collector; and a shaft portion of the electrode terminal penetrates through the current collector. A part of the electrode terminal projecting out from a pass-through of the current collector is a (conical) frustum-shaped portion whose bottom base is in contact with the current collector. The frustum-shaped portion is pressed against the current collector, and the frustum-shaped portion and the current collector are welded together in at least one area on a perimeter of the bottom base of the frustum-shaped portion.
Abstract: This invention is characterized in that, a gate electrode 27F formed on a P-type well 3 via a gate oxide film 9, a high-concentration N-type source layer and a high-concentration N-type drain layer 15 respectively formed apart from the gate electrode and a low-concentration N-type source layer and a low-concentration N-type drain layer respectively formed so that they respectively surround the N-type source layer and the N-type drain layer 10 and respectively parted by a P-type body layer formed under the gate electrode 27F are provided.
Abstract: The present invention relates to a television receiver capable of receiving at least digital satellite broadcasting such as CS broadcasting. The television receiver according to the present invention comprises first means for displaying a plurality of program guides in a matrix shape on a display device utilizing one of the horizontal axis and the vertical axis as a channel number axis and utilizing the other axis as a time axis, and second means for displaying air times for the program guides displayed on the display device in the shape of a bar graph that is long along the time axis.
