  • Patent number: 8270015
    Abstract: An image processing apparatus enables a user to widely select a desired transfer method, in relation to methods of transferring image data to be output to a transfer destination. To accomplish this, the image processing apparatus allows the user to set instruction information for instructing a transfer method of image data, and decides on a transfer method based on the set instruction information if the image data is color data. This transfer method includes a first transfer method of transferring color image data, a second transfer method of converting color image data to monochrome image data and transferring the monochrome image data, and a third transfer method of storing color image data in a storage unit and transmitting a report showing that image data has been received to a transfer destination printer.

  • Patent number: 7873146
    Abstract: A compact apparatus can form multi X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

  • Patent number: 6104906
    Abstract: A blade device includes an elongated elastic blade, and a support member, disposed along a longitudinal direction of the elastic blade, for supporting one end of the elastic blade in a direction perpendicular to the longitudinal direction. Lateral end sections of the elastic blade in the longitudinal direction are more protruded than a central section thereof in a direction opposite to the support member. Portions of the support member corresponding to protruded portions of the elastic blade and supporting the elastic blade are retracted toward a direction opposite to a protruding direction of the elastic blade. The support member may be made of different shapes to achieve the retracted configuration. In addition, the support member may be made of two different materials so that portions of the support member have different elasticities.

  • Patent number: 6100996
    Abstract: When a status change of a printer engine occurs, a status change signal is output to an image data output apparatus. In response to input of the status change signal, the image data output apparatus inquires or confirms the printer engine what kind of status change occurs so that processing to compensate for the status change will be subject to image data to be output to the printer engine.

  • Patent number: 5142525
    Abstract: Disclosed is a communication terminal apparatus for use in a communication system in which at least one line having a plurality of channels is used by a plurality of communication apparatuses (4, 5, 6, 7, 8, 9, 10), wherein when all the information channels are engaged, the idle condition thereof is automatically monitored, and a call is originated when the idle condition is detected, thereby eliminating the wastefulness of operation and improving the efficiency of the line. In particular, when the communication terminal apparatus is connected to a subscriber's line (3) of an ISDN system, communication is effected by using B channels, and if all the B channels are found to be busy upon origination of a call, the idle condition of one of the B channels is monitored from the contents of a D channel, a call being originated again when a B channel becomes idle.
