Apparatus and method for selectively engaging and securing an array of shelf dividers to a mounting device which is securable to a display shelf. In the first form a divider is characterized by a divider structure having an elongated vertical wall and elongated horizontal base that operates to divide, organize and support the displayed merchandise. A resilient latch located on the underside of the base of the divider structure selectively engages and secures the divider structure onto a mounting device comprising a receiving member running longitudinally along the length of the surface of the mounting device which is securable along the front edge of a display shelf. The latch and the receiving member each comprise reciprocating (i.e. complementary) protrusions to allow the cooperative engagement of the divider structure and mounting device, thus locking the divider member to and unlocking the divider member from the mounting device to permit the repositioning of the display as desired without necessitating removal of the merchandise from the display. In addition when the divider structure and mounting device are fully engaged, a second protrusion on the underside of the divider member cooperates with a flange or lip on the mounting device to prevent lateral movement of the divider structure and maintain the position of the divider perpendicular to the mounting device and the front edge of the shelf. In a second embodiment, the divider structure comprises a pusher track and a spring urged pusher assembly to automatically push merchandise to the front of the shelf. Another embodiment comprises a divider base without a vertical divider wall, and with or without a pusher track and spring urged pusher assembly, thus pushers and dividers can be used in various convenient combinations within a shelf management system.

The adjustable tension shade includes a spring motor, an axle, and a shade roller. The spring motor is mounted to the axle and drives the shade roller. The axle has an adjustable telescoping shaft and the free ends of the axle are spring-biased outwardly away from each other. The shade roller has a tubular body that surrounds the axle and the spring motor and serves as a mounting point and storage unit for a shade. A pair of feet is connected to each end of the axle and each has a soft rubber gripping surface thereon.

The present invention provides methods and systems for digitally processing audio signals in two-channel audio systems and / or applications. In particular, the present invention includes a first filter structured to split a two-channel audio input signal into a low frequency signal and a higher frequency signal. A M / S splitter is then structured to split the higher frequency signal into a middle and a side signal. A detection module is then configured to create a detection signal from the middle signal, which is used in a compression module configured to modulate the side signal to create a gain-modulated side signal. A processing module is then structured to combine the low frequency signal, middle signal, and the gain-modulated side signal to form a final output signal.

A method for manufacturing a semiconductor device by a small number of processes and by a means with high usability of materials to have high-definition and a gate insulating with a high step coverage property is disclosed. According to the present invention, a method for manufacturing a semiconductor device comprises the steps of forming a plurality of first conductive layers over a substrate; forming a first insulating layer to fill the gaps of the plurality of the first conductive layers; forming a second insulating layer over the first insulating layer and the plurality of the first conductive layers; and forming a semiconductor region and a second conductive layer over the second insulating layer.

A planar antenna manufactured by patterning a substrate consisting of a dielectric layer, and first and second conductive layers applied, respectively, to both opposite surfaces of the dielectric layer. A first slot is formed in the first conductive layer for radiating electric waves. A second slot is formed in the first conductive layer for intercepting a particular frequency of the electric waves radiated by the first slot. A power supply portion is formed with the first conductive layer for supplying electric current to the first slot. A radiating element formed with the second conductive layer, which is excited by the electric waves radiated by the first slot, and radiates the electric waves.

A removable draft excluder for excluding drafts by sealing a gap between a bottom surface of a door and an underlying floor surface includes a first and a second sleeve, each having a generally elongated configuration for respectively receiving a first and a second blocking member, and a base section extending between the sleeves and maintaining the latter in a generally parallel and spaced apart relationship relative to each other. At least one of the sleeves defines longitudinally opposed sleeve first and second ends. One of the ends of the at least one sleeve is open and foldable about a fold line towards the other end of the at least one sleeve, which is closed, into a folded configuration so as to retain a respective one of the blocking members inside the sleeve between the sleeve ends. A fastening device releasably maintains the sleeve foldable end in the folded configuration.

A chair with a hip-shaping seat is provided with a base, a seat and two elastic members. The seat is formed by two seat members, and on the top of each of the seat members is formed an arc-shaped surface. The two seat members are pivoted connected at one end, and are capable of opening and closing at another end, so that the width of the seat space can also be adjusted to fit different sized hips, through pivoting of the seat members. Hence, the chair of the present invention is capable of effectively holding the hip and preventing the hip from sagging.

This invention relates to an apparatus for securing a projector. The apparatus is mountable to a ceiling drop pipe and comprises a cage and a drop pipe connector assembly. The cage has a plurality of interconnected members that together define an enclosure for housing a projector and impeding removal of the projector from the cage. At least some of the members are connected together by a member fastener that is fastenable only from inside the cage. The position of at least some of the members can be adjusted relative to other members so that the size of the enclosure can be adjusted to fit the projector snugly therein, thereby impeding access to the fastener.

A vehicle loading ramp (10) broadly comprises a first load-bearing platform (16), a second load-bearing platform (20) preferably substantially identical to the first platform (16), and a brace (20) that can be positioned between the platforms (16,18) in order to adjust and rigidly fix a distance between the platforms. In each of several embodiments, the brace (20) may be configured to adjust the distance between the platforms (16,18) in order to accommodate different offsets between wheels of different wheeled vehicles. The brace (20) can also fix the distance between the platforms (16,18), thereby providing rigidity and preventing the platforms (16,18) from moving with respect to one another, either laterally or longitudinally.

An impact drill includes a first ratchet rotating along with a spindle and movable in an axial direction, a second ratchet engaged with the first ratchet and movable in a axial direction but unrotatable, and a spring provided between the second ratchet and a partial member of a housing. An amount of movement of the spindle in the axial direction is regulated, so that the pressing force is too excessive, the restoring force of the spring urging the second ratchet is controlled to maintain a state of generating a set stroke force.
