  • Patent number: 6780257
    Abstract: A base plate of a stainless-steel body material formed by pressing is polished and cleared of burrs by means of an abrasive material that consists mainly of Fe2O3 in a polishing process. The polished base plate is heated to a heat treatment temperature for solid solution in a reducing atmosphere in a heat treatment process. In this heat treatment process, an oxide in the constituents of minute fragments of the abrasive material in the surface of the body material of the base plate is reduced to leave iron, which is dispersed into the body material.

  • Patent number: 6219110
    Abstract: Light emitted from a white light source is separated into red, green and blue light beams by dichroic mirrors. The resulting light beams are directed onto a lenticular lens system having large-pitch lenticular lenses and small-pitch lenticular lenses formed on opposed surfaces. This lens system converts the red, green and blue light beams incident on each of the large-pitch lenticular lenses into a color band set consisting of a set of separated subbands of the red, green and blue light beams the diameter of which is narrowed down to one-third or less of that of the incident light beam through the small-pitch lenticular lenses. The resulting color band sets emerging from the small-pitch lenticular lenses are focused onto a DMD panel through a mirror galvanometer and a coupling lens. The mirror galvanometer is rotated in such a way as to move the color band sets over the DMD panel up and down by the amount corresponding to the pitch of the color band sets while the DMD panel is being driven.

  • Patent number: 5880447
    Abstract: To provide an output data controller which is capable of protecting the secrecy of print data and enhancing operability and where the degree of freedom of system constructability is high. In a file server, ID data is added to the header file of the print data stored in a first queue, and data representative of copy printing is added to the header file stored in a second queue. In security print mode, print data is not output to a printing device, if an ID and a password number collate with each other in a print server. In copy print mode, print data with data representative of copy printing is selected and output to the printing device.

  • Patent number: 5869824
    Abstract: The output data controller is provided with a data printing area for storing print data. Management data is generated by the attribute data of a banner page and is stored in a management table. Based on the management data stored in the management table, the print data stored in the data printing area is managed.
