    摘要: The image processing equipment produces an image of enhanced quality, having dots with higher density than in an original image, by collating an original image with templates. The present invention reduces required number of templates. Original image data in a collation window is either mirror-converted, flip-converted or flip-and-mirror-converted in an array converter (33) and selected on a time-division basis to collate with a single template pattern (34). The effect is equivalent to the collation with maximum four templates. Thus the number of template patterns to be prepared is greatly reduced. Also, by preparing additional patterns to be stored into an area that became vacant attributed to the reduction of patterns, more sophisticated image enhancement may be attained.

    摘要: A device for diagnosing wear on the sliding surface of a piston ring (07a) on a piston (01) which is reciprocating inside a cylinder (02), as applied in diesel engines and compressors, etc. A through-hole (103) is bored in the cylinder wall (02) to extend from the exterior to the interior, and an electric displacement sensor (100) such as, for example, an eddy current type displacement sensor, is inserted into the through-hole inwardly toward the cylinder. The displacement sensor is utilized to measure a difference in an amount of wear between one piston ring (07a) coated with a wear resistant material (102) and another piston ring (07b, 07c, 07d) without wear resistant material coated thereon, and its initial data and data to be collected after use are computed (114), permitting an operator to diagnose the wear on the piston rings based on the change in thickness of the wear resistant material in use.

    摘要: An image forming apparatus includes a plurality of image bearing members bearing latent images, image forming units for forming the latent images on the image bearing members, developing units for developing the latent images on the image bearing members, a transport belt for transporting a transfer member on which images of different colors developed by the developing units are successively transferred as the transfer member is transported, and image pickup elements, arranged obliquely to a main scan direction of the image forming units and located on a downstream of a most downstream one of the image bearing members along a direction in which the transport belt transports the transfer member. The image pickup elements detect as image information transmitted or reflected light quantity distributions of regions which include marks transferred on the transport belt from the image bearing members. The image forming apparatus further includes a correction unit for detecting correction quantities from error quantities of marks transferred from the image bearing members other than a reference image bearing member with respect to a reference mark transferred from the reference image bearing member based on the image information detected by the image pickup elements, and correcting positions of the latent images formed on the image bearing members other than the reference image bearing member depending on the correction quantities.

    摘要: In data communication among a plurality of component units in an apparatus, transition state information corresponding to a state transition which has occurred in a sending side unit is sent to a receiving side unit in serial communication. In the receiving side unit, a state control signal is regenerated at the time when a given delay time has elapsed from the occurrence time of the state transition. Therefore, the state control signal can be sent in serial communication without any time skew. Also, in serial communication between the sending side unit and the receiving side unit, even if a control command signal is to be sent, in addition to the state control signal, a transition state information can be identified from the received signal, by means of adding identification information to the sending information.
