Abstract: A wafer surface treatment device and a method thereof are disclosed. The wafer surface treatment device includes a main body internally defining a treatment space; a movable door provided on one side of the main body; a gas atomizer provided in the treatment space; a heater provided in the treatment space; and a control unit connected to the gas atomizer and the heater.

Abstract: A liquid transfer apparatus comprises an output terminal device, a receiving terminal device, a connecting pipeline, and a control device. The output terminal device includes a first pressurizing member for filling the first storage container with high-pressure air. The receiving terminal device includes an air pressure adjusting member for adjusting the air pressure inside the second storage container. When the liquid transfer apparatus is in a non-transferring state, the air pressure inside the second storage container is high enough to prevent the liquid in the first storage container flow into the connecting pipeline. And when the liquid transfer apparatus is in a transferring state, the pressure difference between the inside of the first storage container and the inside of the second storage container is sufficient to drive the liquid in the first storage container to enter the second storage container.

Abstract: A document pressing structure is provided in a flatbed scanner for facilitating close contact between a document to be scanned and a scanning platform to maintain a constant depth of field. The document pressing structure includes a first coupling element mounted on the cover of the scanner, and a second coupling element mounted on the housing of the scanner. The first and the second coupling elements engage with each other when the cover is pivotally put down on the scanning platform so as to allow the cover to press a scanned face of the document close to the platform.

Abstract: The present invention relates to an image scanner with a self-driven scanning module. The scanner comprises a housing having a transparent platform on its top for placing a document, a track mechanism installed inside the housing along a front-and-rear direction of the housing, a scanning module mounted on the track mechanism slidable along the front-and-rear direction for scanning the document, and a driving device installed on the scanning module having a roller wheel and a motor for driving the roller wheel to move the scanning module back and forth along the track mechanism.

Abstract: The present invention discloses a scanning device using two parallel wheel sets to maintain scanning direction of its scanning module. The scanning device comprises a housing, a scanning module and a driving device. The housing comprises a transparent platform set in its top for placing a document, and two parallel tracks installed along left and right directions inside the housing under the transparent platform. The driving device is installed inside the housing for driving the scanning module along the two parallel tracks to scan the document. The scanning module is slidably mounted on the two parallel tracks for scanning the document. It comprises an elongated image sensor having two ends, and two wheel sets installed under the two ends of the image sensor separately for engaging the two parallel tracks.

Abstract: A scanning device which will take samples from different positions to increase its resolution. The scanning device comprises a housing, a scanning module, and a driving device. The housing comprises a transparent platform installed on its top for placing a document. The scanning module is installed inside the housing and is slidable along a front-and-rear direction for scanning the document. The scanning module comprises a carrier, a sensor, and a positioning device for fixing the sensor inside the carrier. The sensor is installed within the carrier, is slidable along a left-right direction and comprises a plurality of linearly arranged sensing units for taking samples from the scanned document. A driving device is used for driving the scanning module forward and backward to scan the document.

Abstract: The upper housing of a flatbed scanner is provided with a plurality of integrally formed block members for locating a transparent platform on which an object to be scanned is placed. Each block member includes a horizontal block piece and a vertical block piece protruding from the horizontal block piece. The horizontal block piece is a protruding portion extending perpendicular to an internal surface of the upper housing for restricting horizontal movement of the transparent platform and the vertical block piece has a vertical retaining section having an inclined surface which flexes in the horizontal direction as the transparent platform is pushed past the vertical block piece, the vertical retaining section then recovering to vertically secure the transparent platform on the internal surface. The transparent platform can be mounted over the upper housing with no need to use adhesive tape.

Abstract: The present invention includes a casing for forming an upper housing of the desktop scanning device, a rectangular transparent plate for been placed thereon an object to be scanned, and a calibration strip on which light source from the desktop scanning device is projected as a calibration parameter. The calibration strip is mounted on the rectangular transparent plate so that either the upper housing or the surface of the transparent plate will not be damaged if the calibration strip has to replaced during the assembly of the scanning device. Furthermore, a darkened image generated by a gap existing between a background plate of an upper cover of the scanning device and the transparent plate can be prevented during scanning process.
