摘要： PURPOSE:To reduce the burden on the hands and arms of an operator and to improve an operation sense by providing a cushioning member in the surface idle space of a keyboard front part. CONSTITUTION:The idle space mounting a part of incorporated parts is provided by providing a track ball 3 or the like on the side of the operator front part of a keyboard 2. The hands and the arms of the operator are brought into contact with the front surface idle space at the time of operating the keyboard. Thus, the burden of the hands and the arms of the operator is reduced and the touch feeling of an operation improves. At that time, the buffer member 4a is integrated with the front surface space. Thus, it is fixed to an electronic equipment main body 1 by adhesion or the like. Thus, the operation touch feeling of the operator can be improved much more by fixing the buffer member 4a matched to the preference of the operator in a case when the hands and the arms of the operator are brought into contact with the front surface idle space of the keyboard 2 front part.

摘要： PROBLEM TO BE SOLVED: To increase redundancy of cooling means of a plurality of semiconductor devices by forming a duct through which cooling air supplied by first and second cooling fans for supplying cooling air to a board flows toward the board. SOLUTION: Since first and second cooling fans are arranged along the flow direction on a passage of a cooling air 10 formed by a duct, even if the first cooling fan of a heat sink with fans is stopped, cooling air from the second cooling fan 6 reaches the heat sink. Further, the duct constructs the passage so that the cooling air 10 flows toward a board or a heater element. As a result, the cooling air 10 flows into the heat sink with fans and is blown onto the board 4 via the heat sink. Thus, even when the first fan is stopped, the cooling air can be supplied to the heater element on the board 4 and a rise in the temperature of an LSI package and an IC chip can be suppressed.

摘要： PURPOSE:To obtain an electroconductive fiber composite resin suitable for electromagnetic shielding of electronic equipment by a method wherein bundle conductors, each of which consists of fine strands and essential ingredient of which is iron-based metal fiber, are continuously fed by means of an extruder so as to be coveringly imbedded in thermoplastic resin matrix and the resultant composite resin is cut to proper lengths. CONSTITUTION:Electroconductive fibers are composed of at least two kinds of fibers selected from the group consisting of iron-based metal fibers having the cross-sectional diameter of 5-15mum, copper-based metal fibers having the diameter of 15-60mum, aluminum-based metal fibers having the diameter of 15-60mum and metal-clad fibers and the iron-based metal fiber is the essential ingredient of the electroconductive fibers. Further, through the three- dimensional intertwinement of the electroconductive fibers with one another or the presence of their contact points, electroconductive circuits having network structure are produced. Since the stress relaxation characteristics of resin must be higher than a certain level in order to maintain the contact pressure at the contact point, thermoplastic resin having a heat deformation temperature of 80-210 deg.C is used. Furthermore, a crosshead, on which dies 11-13 are mounted, is installed to a double screw extruder so as to continuously feed 2-5 bundles of electroconductive fibers 1, 2 or the like for covering with molten resin 30 in order to obtain a multi-core continuous body. Finally, after being cooled down, the continuous body is cut to proper lengths.

摘要： PURPOSE: To reduce the noise level of a cooling fan by providing in exposing a sound absorbing material along the ridgeline of a housing to a place near an opening at the upper part of the housing.
CONSTITUTION: The sounds produced at an entrance of a fan are radiated into a cover 2 from an upper sucking opening part 6 of a housing 9 in the direction opposite to the air flowing direction. These sounds intend to go into the rear side by a diffraction phenomenon of a sound wave and are radiated to the outside through a cover opening part 10 after passing through a path between the cover 2 and the housing 9. Therefore it is needed to bond a sound absorbing material at a position having high energy density of sound in order to reduce the noise level without increasing the fluid resistance level. The sound absorbing material is bonded at a ridgeline part 8, i.e., a rack of a diffraction part of the sound wave as well as a ridgeline part 12 of the part 10 since these parts have the highest energy density. Thus the noise level can be extremely reduced.

摘要翻译：目的：通过提供将吸声材料沿着壳体的脊线曝光到壳体上部的开口附近的位置来降低冷却风扇的噪声水平。构成：在风扇入口处产生的声音沿着与空气流动方向相反的方向从壳体9的上吸引开口部6辐射到盖2中。这些声音将通过声波的衍射现象进入后侧，并且在穿过盖2和壳体9之间的路径之后通过盖开口部分10辐射到外部。因此，需要将在具有高能量密度声音的位置处的吸音材料，以便在不增加流体阻力水平的情况下降低噪声水平。由于这些部件具有最高的能量密度，吸音材料被接合在棱线部分8，即声波的衍射部分的齿条以及部分10的棱线部分12。因此，噪音水平可以极大地降低。
