  • Publication number: 20240136399
    Abstract: The object is to provide a technology that can shorten a routing length of a gate wire connecting a control IC that controls driving first and second semiconductor elements that are connected in parallel with each other, to a gate pad of one of the first and second semiconductor elements disposed distant from the control IC. A first semiconductor element and a second semiconductor element are disposed so that a long side of the first semiconductor element faces a side of the second semiconductor element, and a HVIC or a LVIC, the first semiconductor element, and the second semiconductor element are disposed in this order in a direction orthogonal to a first direction, the gate pad is disposed on the first semiconductor element on one side in the first direction, and the gate pad is disposed on the second semiconductor element on the other side in the first direction.

  • Patent number: 7145593
    Abstract: The present provides a mobile terminal device includes first and second housings foldably coupled to each other by a hinge portion, and the first housing can turn in the direction orthogonal to the unfolding/folding direction. The mobile terminal device also includes a first camera provided for a surface opposed to said second housing in a state that the device is folded, and a second camera provided for a surface of the first or second housing on the opposite side to the surface having the first camera, when the two housings are unfolded at an angle of about 90° and the first housing turns at an angle of about 90° to the second housing, and a sensor for detecting a positional relation between the two housings according to a change of the angle between the two housings. According to the detected position, operations of the first and second camera are stopped/started.

  • Publication number: 20050158617
    Abstract: An object of the invention is to provide a portable telephone which is easily detachable an information recording medium while avoiding the enlargement of its size. The portable telephone according to the invention includes a battery attachment portion (101c) of a concave shape to which a battery (107) is attached, a step portion (101d) protruded in the drawing-out direction (opposite direction to an arrow D in the figure) of the battery (107) with respect to the bottom surface of the battery attachment portion (101c), a UIM card connector (115) which is disposed near the surface extending across the corners of the step portion 101d and has a configuration that the one major surface of a UIM card (122) exposes on the surface of the step portion (101d) at the time of attaching the UIM card (122), and a battery cover (107a) which covers the step portion (101d) and the battery attachment portion (101c) at the time of attaching the battery (107).

  • Patent number: 4040838
    Abstract: In the high temperature color development processing of color photographic materials, the formation of reticulation and scratches on the surfaces of the photographic films is prevented and drying can be performed in a shortened period of time at a high temperature by processing the color photographic materials in a bleach solution or blix solution containing a metal complex of an organic acid, a water soluble ammonium compound and a magnesium compound.The bleach solution or blix solution does not give rise to environmental pollution and can be easily regenerated for reuse.
