  • Patent number: 10638003
    Abstract: A printing apparatus performs printing using a plurality of sheets different in size. Stored instructions are executed to act as a display control unit displaying an operation guidance on a display unit for setting a sheet in a sheet tray, and a data acquiring unit acquiring regional information of the printing apparatus. When the data acquiring unit acquires regional information indicating a first region, the display control unit displays an operation guidance including content that notifies a user of a specific operation that is to be performed on the sheet tray so that it is able to hold a sheet having a first sheet size. When the data acquiring unit acquires regional information indicating a second region which is different from the first region, the display control unit displays an operation guidance not including the content that notifies a user of the specific operation.

  • Patent number: 6709751
    Abstract: A layer comprising a stain resistant agent is formed on a treated surface of a ceramic product used with water so that a stain resistant treatment is applied to the treated surface. The stain resistant agent includes a silicon-containing functional group combining with the hydroxyl group present on the treated surface by dehydration or dehydrogenation. Consequently, a high stain resistant effect can be achieved from the ceramic product.

  • Patent number: 5964315
    Abstract: An object of the present invention is to provide a power steering apparatus in which its neutral rigidity can be raised by applying a preset force and which is superior in its assembly performance and productivity.To attain this object, first supporting portions are formed in a pair of spring members disposed across the input shaft, and second supporting portions are formed in the input shaft so as to oppose the first supporting portions. When the input shaft and the output shaft are rotated relative to each other so that the balls or rollers are about to slip out of the first and second supporting portions, the balls or rollers roll and move while deflecting the spring members.

  • Patent number: 5871064
    Abstract: A power steering apparatus having enhanced neutral rigidity and improved operation stability at the time of straight traveling. The apparatus includes a pair of spring members which sandwich an input shaft and are disposed in an output shaft or a member rotating integrally with this output shaft. A preset force is exerted by a spring force of the spring members.

  • Patent number: 5220249
    Abstract: A flat type fluorescent lamp device is constituted by two transparent glass plates assembled and sealed together thereby forming a glass plate assembly, a discharge channel formed in a serpentine form by a groove on at least one of the two transparent glass plates with the inner surface of the groove carrying a fluorescent film. A pair of electrodes are provided, electrode each at each end of the discharge channel, a light diffuser provided on the front surface of the glass plate assembly and a light reflector is provided at the back surface of the glass plate assembly. In one aspect of the invention, at least another electrode is provided between the two electrodes thereby dividing the discharge channel into a plurality of individual discharge channels, in which case it is possible to ensure that all of the individual channels have the same electric characteristics and can be caused to be lit in parallel by a single power source.
