An object of the present invention is to provide a touch panel having a press detection function, which makes it possible to suppress degradation of visibility of a display unit of a display device even when mounted on an electronic device, and also to improve a pressure measuring precision. For this purpose, the touch panel of the present invention includes a first substrate, a second substrate disposed oppose to the first substrate, a pair of electrodes disposed on either one of opposed surfaces of the respective substrates or disposed separately on both of the surfaces, pressure sensitive ink members disposed with a gap from at least one of the pair of electrodes, each of the pressure sensitive ink members having an electrical characteristic varied by a pressing force applied thereto, and a gap retaining member for bonding the first and second substrates to each other and for retaining a gap between each of the pressure sensitive inks and at least one of the pair of electrodes, wherein the pair of electrodes are disposed in a frame shape along an edge portion of the first or second substrate, and the pressure sensitive ink members are scattered along the edge portion of the first or second substrate so that, when the first or second substrate is deformed upon an application of an external force, at least one of them is made in contact with both of the pair of electrodes so as to make the two electrodes conductive to each other.

The present invention provides a joining structure of a roof truss using thin light-gauge shaped steel. In a joining structure for joining a subsidiary roof with a main roof, a valley bracket formed by bending a thin steel sheet is inserted and disposed in the longitudinal valley direction of a joining member for joining a rafter forming the subsidiary roof with a truss or a rafter forming the main roof. In a joining structure in which a roof truss upper chord member or a rafter intersects a wall on the upper surface of the wall, a bracket formed by bending a thin steel sheet is disposed at the intersection of these members and fixes the roof truss upper chord member or the rafter to the wall. In a joining structure for the connecting top of the roof truss upper chord member or the rafter, a thin steel sheet member is disposed at the connecting top to fix an end of the roof truss upper chord member or the rafter with an end of a strut, and a box-shaped bracket formed by bending a thin steel sheet to have box-like receiving sections is provided at a top of the thin steel sheet member, for fixing top cleat members.

An HDD has a carriage which moves a head with respect to a medium, and a voice coil motor (VCM) which drives the carriage. The VCM has a magnet, between which and a first shell formed of a magnetic substance a magnetic circuit is formed, and a voice coil which is secured to the carriage and disposed in a magnetic gap. A depression which receives a projecting portion covering a lead of the voice coil is formed in the first shell, and thereby a projection projecting toward the coil is consequently formed. This structure partially narrows the magnetic gap and allows generation of a torque with sufficient intensity.

An optical image capturing device which is configured to carry out underwater photographing, and comprises a selecting section configured to select a plurality of photographing modes including an underwater photographing mode, an imaging member to obtain an object image, and an adjusting section to adjust white balance of an image obtained by the imaging member, is disclosed. The adjusting section adjusts the white balance to enhance a blue component when the underwater photographing mode is selected. Thus, as the white balance is adjusted by the adjusting section to enhance a blue component when the underwater photographing mode is selected, a bluish image apparently photographed in water can be obtained.
