  • Patent number: 6307974
    Abstract: This invention is to transmit read image data to a host device using a transfer mode which guarantees a predetermined band and does not perform error check or retransmission time suitable for the original purpose of prescanning. When a prescanning instruction is received from a host computer (112), a scanner (115) is driven to read an original image, and thinning/interpolation and compression are performed. In addition, transfer through a communication interface USB to the host computer (112) is performed in the isochronous transfer mode which guarantees a predetermined band within a periodically continuous time and does not perform retransmission in response to error occurrence, thereby realizing high-speed transfer.

  • Patent number: 6285460
    Abstract: An image processing system includes an input device which inputs an n page document, with the n pages being reduced in size so that a predetermined number of the n pages can be layed out in a layout print format on a single sheet for recording. A selection device selects between first and second layout modes for laying out the predetermined number of pages in the layout print format for recording. In the first layout mode the predetermined number of the n pages are first layed out in the layout print format and are subsequently stored in a storage device, and are then read from the storage device for recording on a single sheet. In the second layout mode the predetermined number of pages are first stored in the storage device on a page by page basis, are then read from the storage device and are subsequently layed out in the layout print format, and are then recorded on a single sheet.

  • Patent number: 6034761
    Abstract: An apparatus for measuring displacement information of an object. The apparatus has a light source emitting a light beam, an electro-optical crystal member, a voltage applying system for imparting a predetermined frequency difference between light beams passing through two different areas in the electro-optical crystal member, and a light receiving system for receiving scattered light from the object to which the two light beams emergent from the electro-optical crystal member have been projected. The electro-optical crystal member is disposed so that a light beam from the light source may partly enter the two different areas to form the two light beams to which the predetermined frequency difference is imparted. The displacement information of the object is obtained from the scattered light received by the light receiving system.

  • Patent number: 5591385
    Abstract: This invention provides a plastic molding method, a mold, and a molded article. According to this invention, the supply flow rate of a coolant, e.g., cooling water, to a mold is maintained to shorten the molding cycle and to improve the productivity in continuous molding. The temperature distribution and pressure distribution in the mold are measured, thereby realizing determination as to whether a molded article is defective or not in the molding and cooling processes. The temperatures at respective required portions of the molded article removed from the mold are monitored, so that determination as to whether a molded article is defective or not can be performed, thereby improving the productivity. Countermeasures are taken not to deform the molded article. A thermoplastic resin injected from a hot runner into a cavity is heated at a gate discharge portion by a shearing heat upon injection. Countermeasures are taken to suppress temperature increase caused by this heat.
