Abstract:
A container having a top cover and a bottom cover is provided, which includes a canopy disposed on the bottom cover to form therewith a space to accommodate an article. A plurality of locators is disposed on a surface of the bottom cover so that when the bottom cover is tightly combined with the top cover, the locators are clipped between the bottom cover and the top cover to orient the canopy in a fixed position.
Abstract:
A paper-releasing mechanism includes a paper-feeding device for feeding papers, a supporting shelf arranged under the paper-feeding device, a driving roller and an idle roller arranged in the front of the paper-feeding device and an elastic unit engaged with the idle roller and the supporting shelf. The elastic unit includes a connecting arm, act arms bending from the ends of the connecting arm respectively, two helixes each of which extends from the act arm and forms an aperture and two follow act arm each of which extends from the helix and forms a ring at the end thereof, the ring being sleeved on the rolling pivot of the idle roller, the apertures being sleeved on a pivot formed on the supporting shelf.
Abstract:
A sheet-handling apparatus includes a base, a second motor and a sheet-fetching assembly driven by the second motor. The sheet-fetching assembly has a passive gear and a floating gear. When the passive gear rotates, the floating gear revolves around the passive gear. A plurality of driving rollers are driven by a first motor. A plurality of driven rollers are driven by driving rollers, respectively. A prop assembly includes a brace arranged in the base, a prop axel engaged in the brace, a twist arm fixed at the prop axel and having a plurality of teeth for contacting with the floating gear, a swimming arm sleeved and firmly engaged with the swimming arm and a spring component installed on a support board of the swimming arm. The passive gear drives the floating gear descending and ascending. There are two motors provided in the sheet-handling apparatus in order to simplify the structure of the sheet-handling apparatus.
Abstract:
A method for improving etch uniformity during a wet etching process is disclosed. The method comprises the steps of first rinsing the wafer to form a water film over the wafer surface, followed by liquid phase etching. The water film helps the subsequent viscous etchant to be spread across the wafer surface more uniformly to thereby improve the etch uniformity.

Abstract:
A hologram media reading apparatus including a reference light source, a stop with gray level aperture, and an optical sensor is provided. The reference light source is disposed on one side of a hologram medium, and capable of emitting a reference light beam. The reference light beam is transmitted to the hologram medium. The stop with gray level aperture and the reference light source are disposed on the same side or opposite sides of the hologram medium. The stop with gray level aperture has a light transmissive region, an opaque region, and a transmittance gradually varying region. The opaque region surrounds the light transmissive region. The transmittance gradually varying region surrounds the light transmissive region. A part of the reference beam from the hologram medium passes through the stop with gray level aperture and is transmitted to the optical sensor.
Abstract:
A holographic storage and regeneration system includes a holographic recording medium, a light source, a spatial light modulator, and a conjugate servo light guidance portion. The light source generates a signal light and a reference light. The spatial light modulator modulates the incident signal light and makes it incident onto the medium along the incident direction of the signal light. The guidance portion guides a reference light to incident onto the medium in one direction and reflects it in another direction. A reference light and a signal light interfere with each other to produce a holographic interference fringe. The reflected reference light is guided into a first image sensor to be used to analyze the incident angle of the reference light. When the reference light incidents onto the fringe of the medium through the guidance portion in a reverse direction relative to another direction, a conjugate regenerated light is generated.
Abstract:
A micro USB receptacle includes a housing surrounding an axis, a terminal seat extending into the housing along the axis, and an engaging unit. The engaging unit has a first engaging member provided on the terminal seat, and a resilient second engaging member provided on the housing and having an engaging hole for retaining the first engaging member therein and an inner surrounding surface that defines the engaging hole. The first engaging member is formed with a stop surface for abutting against the inner surrounding surface of the second engaging member to arrest separation of the terminal seat from the housing.
