    摘要: A device for removing document jamming generated at a platen roller and a contact image sensor of a facsimile comprising sensor brackets mounted to opposite ends of the contact image sensor and pivotally mounted to both sides of a main frame of the body of the facsimile, so as to pivotally move the contact image sensor, each of the sensor brackets having an operating portion, and cam members each having a cam surface being in contact with the operating portion of the corresponding sensor bracket. Each cam member pivotally moves the contact image sensor between its operation position where it is in contact with the platen roller and its document jamming removal position where it is separated from the platen roller to form a gap therebetween. An actuating lever is connected to the cam members for moving it between a first position corresponding to the operation position of the cam members and a second position corresponding to the document jamming removal position. In the device, a certain gap can be formed between the platen roller and the contact image sensor, only by the manipulation of the actuating lever disposed outside of the facsimile body.

    摘要: A heat sink board structure includes a thermal/structural base having a composite core layer of a mass of graphitized carbon fibers infiltrated with a first resin material matrix. The graphitized carbon fibers of the composite core are substantially unidirectional and oriented parallel to the face of the composite core layer. Transverse reinforcement layers are bonded to the oppositely disposed faces of the composite core layer. Each transverse reinforcement layer is formed of carbon fibers embedded in a resin material matrix, with the carbon fibers lying substantially in a plane of the transverse reinforcement layer and perpendicular to the carbon fibers in the composite layer. Heat generating and heat dissipating components are bonded to the thermal/structural base. Metallic contact strips are bonded to the surfaces of the transverse reinforcement layers.

    摘要: A method for autofocusing a video camera, adjusting the focus by defining the focus range in which the contrast signal is extracted, generating the control clock pulse having higher frequencies than the video signal during the occurrence period of horizontal and vertical synchronizing signals corresponding to the focus range, sampling the video signals obtained in the image pick-up elements by means of the control clock pulses, converting this sampled signal into digital signal, generating the digital differential signal which represents the difference between the values of one control clock pulse earlier one and current one, producing the digital weighted signal by transforming the digital differential signal by means of the nonlinear weight value, integrating the digital weighted signals for one or more fields or frames to obtain the focusing value, and moving the focusing lensd based on the focusing value to the location where the focusing value approximately reaches the maximum.
