Abstract: An outdoor unit includes a dish antenna and a low noise block converter positioned at a focus point of the dish antenna. The low noise block converter comprises a housing, a feed cap disposed on top of the housing, and an air permeable membrane disposed on a bottom portion of the housing. The housing includes a base portion, at least one feed horn protruding from the base portion, and a bottom cover attached to a bottom of the base portion so as to form a housing cavity, wherein the bottom cover has a vent hole forming a flow path between the housing cavity and an external environment. The feed cap is disposed on a feed portion of the at least one feed horn and the air permeable membrane is disposed over the vent hole and coupled to the bottom cover via an adhesive, wherein the membrane is configured to permit egress of a gas from the housing cavity therethrough.

Abstract: A microwave resonant cavity includes a conductive shell with a screw hole having first threads and a screw having second threads configured to engage with the screw hole. The conductive shell defines a volume, the screw extends into the volume, the microwave resonant cavity has a resonant frequency, and the movement of the screw changes the resonant frequency. The first threads have a first pitch, and at least a portion of the second threads has a second pitch different from the first pitch.

Abstract: A structure of a voice coil assembly includes a plate, a top board, suspending arms and fixtures. The plate has a top and two opposite sides. The top board is disposed on the top of the plate. The suspending arms extend from the two sides of the plate and are connected to the fixtures. A pair of resilient sections is provided between the suspending arms and the fixtures. The resilient sections are formed in a curved, arcuate or wavy shape. The suspending arm has a cross-section in a flat shape.

Abstract: A method for manufacturing a loudspeaker having a voice coil assembly includes the steps of: producing a flat voice coil; placing the voice coil into an injecting mold of a vibrating slab; forming a locating section to secure the voice coil; and assembling a loudspeaker by coupling the vibrating slab with a membrane together to produce a better sound quality. Furthermore, upper suspending arms provided on respective sides of the vibrating slab may be cut to lower the rigidity character of the vibrating slab and to increase the vibrating effect.

Abstract: A positioning device for positioning an integration rod module disposed in an optical path between a light source device and a projection lens within a projection apparatus includes a flexible element having a fixing plate section mounted securely on an inner surface of a casing interconnecting the light source device and the projection lens and enclosing the integration rod module, and a first distal plate section extending integrally from one end of the fixing plate section toward a rod cover mounted on the casing for resiliently urging a holder of the rod module to press against the inner surface of the casing at a position opposite to the flexible element. A stop member is disposed securely on the holder adjacent to the rod cover to facilitate abutment of the first distal plate section of the flexible element against the holder to enhance retention of the rod module within the casing.

Abstract: An angle-adjusting mechanism includes a first disk, a second disk, a fixing element and an elastic element. The first disk has a spindle hole and a plurality of positioning end notches disposed adjacent to the spindle hole. The second disk has a spindle fitting the spindle hole to enable the first disk to rotate around a rotation axis of the spindle relative to second disk, and has a positioning end bump located adjacent to the spindle to engage with one of the positioning end notches. The fixing element mounts the second disk onto the supporting bracket and limits the second disk to move along the rotation axis of the spindle within a preset range. The elastic element is mounted between the fixing element and the second disk to force the second disk to lean on the first disk.

Abstract: An elevating mechanism for a projection apparatus includes a base, a movable leg, an elastomer, a decelerating module and a fixing component. The base is connected with the projection apparatus and has a slide, an accommodating space and an opening disposed at one end of the base. The accommodating space is located inside the base and communicated with the opening. The slide is in a sidewall of the base and communicated with the accommodating space. The movable leg is disposed through the opening and the accommodating space, and one end of the elastomer is disposed on the base. The movable leg is suitable for protruding from the opening of the base by the elastomer. Moreover, the decelerating module is disposed on the movable leg and is in the slide. The decelerating module is suitable for contacting with the base. The fixing component is suitable for fixing the movable leg.

Abstract: A backlight button assemblage includes an opaque button, a light-guiding element, and a light-emitting element. The light-emitting element is disposed under the button and light emitted from the light-emitting element is guided to the front side of the button via the light-guiding element surrounding the button. Light can therefore be evenly distributed over the light-guiding element, and uniformity of light achieved, so that partial dazzling spots are avoided, the quantity of light-emitting elements is reduced, and fabrication costs are saved.
