A cylindrical bonding structure and its method of manufacture. The cylindrical bonding structure is formed over the bonding pad of a silicon chip and the chip is flipped over to connect with a substrate board in the process of forming a flip-chip package. The cylindrical bonding structure mainly includes a conductive pillar and a solder cap. The conductive pillar is formed over the bonding pad of the silicon chip and the solder cap is attached to the upper end of the conductive pillar. The solder cap has a melting point lower than the conductive pillar. The solder cap can be configured into a cylindrical, spherical or hemispherical shape. To fabricate the cylindrical bonding structure, a patterned mask layer having a plurality of openings that correspond in position to the bonding pads on the wafer is formed over a silicon wafer. Conductive material is deposited into the openings to form conductive pillars and finally a solder cap is attached to the end of each conductive pillar.

The present invention relates to a door for an appliance. The door has a front panel and a rear panel and edges extending between the front panel and rear panel to create an internal cavity between the front panel and the rear panel. A filler material is contained in the internal cavity, and an intermediate material is interposed between a rear surface of the front panel and the filler material. The intermediate material or front panel is adapted to retain the front panel relative to the filler material by a magnetic field and release a portion of the front panel relative to the filler material upon excessive localized deformation of the filler material.

An apparatus that provides shock absorption and ejection for a payload that is to be deployed from a launch capsule is disclosed. The payload ejection mechanism comprises a movable housing that houses a resilient member and a shock-damping system. The rapid acceleration of the capsule upon launch causes the movable housing to move, which compresses the resilient member, thereby storing energy. Movement of the housing also provides shock damping behavior. A locking mechanism maintains the compression of the resilient member until the capsule opens to deploy the payload. As the capsule opens, a restraint decouples from the locking mechanism and permits the resilient member to expand. Expansion of the resilient member causes the movable housing to move, thereby propelling the payload away from the capsule.

The invention discloses a projection screen and an ultra-short-focus projection system. The projection screen receives image light beams emitted by a projection device, and comprises a reflecting layer, a lens layer, an isolation layer and a scattering layer, wherein the isolation layer is arranged between the scattering layer and the lens layer; the image light beams pass through the scattering layer, the isolation layer and the lens layer in sequence and reach the reflecting layer after being emitted from the projection device; and after being reflected by the reflecting layer, the image light beams pass through the lens layer, the isolation layer and the scattering layer again and then, enter the human eyes. The ultra-short-focus projection system comprises the ultra-short-focus projection device and the projection screen. Laser generated by the ultra-short-focus projection device is projected onto the projection screen to form an image on the projection screen. The projection screen and the ultra-short-focus projection system can obviously reduce speckles of the projection screen.
