20080197088 | Housing Structure of Acoustic Controller - A housing structure of an acoustic controller having a lower case which is lightweight, high in the degree of freedom in shape design, and capable of suppressing a deformation of side walls thereof after being molded. The lower case is integrally formed from resin into a rectangular dish shape having front, rear, left, right, and bottom plates. An upper unit is attached to an open upper part of the lower case. The left and right plates of the lower case have upper parts thereof formed into brim portions protruding outward in the left-to-right direction. Front and rear parts of each brim portion are further protruded outward and formed into flanges that function as mounting portions used for mounting the acoustic controller to a rack. | 08-21-2008 |
20080198558 | Housing Structure of Acoustic Controller - A housing structure of an acoustic controller, in which a lower case of the controller has an increased rigidity and improved moldability. The lower case is integrally formed by a resin and has a bottom surface thereof disposed to face a tabletop surface when the controller is in a stationarily placed thereon. The bottom surface of the lower case is formed to have a concave-forming portion that defines a concave space communicating with the outside of the controller on the left and right sides thereof and which is upward convex as viewed when the controller is stationarily placed, thus increasing the rigidity of the lower case. Bosses and vertical ribs formed to project upward from a horizontal part of the concave-forming portion of the lower case each have a reduced height, thereby improving the moldability of the lower case. | 08-21-2008 |
20150144420 | ACOUSTIC EQUIPMENT - A distal end of an inserted pole makes contact with a bottom surface or tapering surface of a portion corresponding to a bottom of an insertion hole. A lever rotates about a pivot shaft, and a pressing surface facing from a recessed portion formed in the insertion hole presses a side surface portion of the pole. The pole pressed by the pressing surface is mainly received by ridge portions, particularly the ridge portions positioned on the opposite side with a central axis therebetween in relation to the pressing surface. The ridge portions are positioned on both sides of the pole with the cross section along the line A-A therebetween as viewed in the axial direction. As the lever is rotatably operated in the tightening direction, the pressing position gradually approaches the central axis, thereby increasing the pressing force. | 05-28-2015 |
