A bow sight is comprised of at least two support structures, at least one of the support structures supporting at least one angled sight pin. Each support structure is adjustably attached to a mounting member that allows individual vertical adjustment of each support structure and thus individual vertical adjustment of each sight point of the sight pins.

A blower system, wherein a blower case and a motor holding housing are comprised as separate members, a spiral casing is provided with an enlarged part enlarged in an axial direction to an opposite side from the suction port from a centrifugal type blower fan. The motor holding housing is provided with a holder storing and holding the motor, an extension extending from the holder in a diametrical direction of the fan, a circumferential wall connected with the extension and forming an inner circumferential wall of the enlarged part in the spiral casing. A cooling air passage is provided between the holder and the circumferential wall to guide part of the air circulating inside the spiral casing to the motor. The cooling air passage has an inlet into which air flows from the spiral casing and an outlet at the circumferential wall, out of which air flows to the motor.

A mobile communication terminal is provided with a speaker having a size suitable for music appreciation and is implemented without widening the mobile communication terminal or decreasing an area of a display. Furthermore, mixture between sound emitted toward a front side of the speaker and sound emitted toward a rear side of the speaker is prevented as is leakage of sound from the body of the mobile communication terminal.

There is provided a multilayer ceramic electronic component including: a ceramic body in which a plurality of dielectric layers are stacked; a plurality of first and second internal electrodes formed on at least one surfaces of the dielectric layers and alternately exposed through both end surfaces of the ceramic body in a length direction of the ceramic body; a first acoustic noise absorption layer formed on one surface of the ceramic body in a stacking direction of the dielectric layers and having a thickness of 3 μm to 500 μm; first and second external electrodes formed on both end surfaces of the ceramic body and electrically connected to exposed portions of the first and second internal electrodes; and a printed circuit board having the first and second external electrodes mounted thereon while facing the first acoustic noise absorption layer.

A steering device includes a column shaft, a column jacket, a fastening mechanism including a fastening shaft having a first flat portion, a first tooth member, a second tooth member, an energizing member, and a release member including: a cylindrical portion having a second flat portion; and a release portion, wherein: the release member is configured to cause the release portion to be engaged with the second tooth member; and a projecting portion formed on at least one of the first flat portion and the second flat portion is elastically engaged with the other one of the first flat portion and the second flat portion and restrain backlash between the first flat portion and the second flat portion.

A disk brake including friction pads disposed opposite to a brake disk, a bracket provided with support portions for movably supporting the friction pads so as to permit sliding along the axial direction of the brake disk, and retainers each interposed between the friction pad and the support portions, to restrain at least movements of the retainers relative to the support portions of the bracket. Of a pad holding force with which the retainer holds the friction pad, and a retainer supporting force for supporting the retainer on the support portion, at least the retainer supporting force is set to be not less than a received force exerted on the friction pad due to vibration. The resulting configuration prevents generation of rattling sounds due to the vibration.

The invention discloses a special stationery storage box for students, which comprises a first box cover and a box body, a second box cover is provided on one side of the box body, a pen case is provided at the upper end inside the box body, and a pen case is provided at one end of the pen case slot, one side of the pen box is provided with a first storage box, one side of the first storage box is provided with a second storage box, one side of the second storage box is provided with a third storage box, and the inside of the third storage box is snapped There is a pencil sharpener, a drawer box is arranged in the box body at the bottom of the pencil case, and a rotating box is arranged in the box body at the bottom of the drawer box. The beneficial effects of the present invention are: the student-specific stationery storage box, by arranging a plurality of storage boxes for fixing files in the box body, and making the stoppers cooperate with each other, the stationery in the box body is fixed, and at the same time, the stationery in the box can be fixed without opening the box. In the case of the cover, the stationery can be taken out of the box through the second cover on the side, so that it is no longer necessary to open the cover when taking and placing frequently used stationery, thereby avoiding the sound produced when taking and placing the stationery.

The invention relates to a built-in antenna module for a wireless communication terminal. The module includes at least one radiator. The module also includes a base having an inner space, disposed on a board of a terminal body, and having the radiator on an outer surface thereof to enable electric connection between an end of the radiator and the board of the terminal body.

The invention efficiently utilizes a limited space in the terminal body with enhanced capabilities of the antenna.

A rugged noise muffler system is configured to substantially surround sound-emitting openings in a working unit or structure, to absorb sound emitted from the sound-emitting openings. A barrier component, formed as a housing, covers a sound emitting opening to inhibit sound from emanating from the housing, except at an open end of the housing. Each sound emitting opening in the working unit or structure requires a housing positioned over same. The housing includes a hood portion and an elongate portion that includes the open end of the housing. The inner surfaces of the hood portion and an elongate portion are lined with sound absorbing material. The emitted sound first enters the hood portion, is partially absorbed therein and any unabsorbed sound passes into and is substantially absorbed in the elongate portion as the sound travels towards the open end of the housing,
