| 20090316155 | Reflection Type Encoder, Scale Thereof and Method for Producing Scale - A reflection type encoder, which receives a plurality of light-receiving signals from a single scale, includes a light source, a scale having a plurality of patterns formed thereon to which light is irradiated from the light source, and a light-receiving element for receiving light reflected from each of the plurality of patterns, wherein a plurality of patterns each having different thicknesses are formed on a single track of the scale by using a dielectric substance, light of a plurality of wavelengths each having different brightnesses in accordance with differences in the thickness of the dielectric substance is irradiated from the light source, and a light-receiving signal is obtained for the respective thicknesses of the dielectric substance. Therefore, the scale can be downsized by overlapping a plurality of patterns on the same track. | 12-24-2009 |
| 20100270461 | PHOTOELECTRIC ENCODER AND METHOD FOR CONTROLLING OPERATION OF THE SAME - A photoelectric encoder includes: a scale provided with a first optical grating; a detector unit opposed to the scale; and a light source integrated with the scale, the light source emitting light to be modulated by the first optical grating and received by the detector unit. | 10-28-2010 |

| 20110085827 | IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOF - This invention provides an image forming apparatus capable of effectively suppressing an AC color registration error, and a control method thereof. To accomplish this, the image forming apparatus according to this invention controls driving of a transfer belt so that the speed of surface of the transfer belt at the transfer position comes close to a constant speed. The image forming apparatus also controls driving of a photosensitive drum so that the error between the speed of surface of the photosensitive drum and that of the transfer belt at the transfer position becomes almost 0. Further, the image forming apparatus controls the exposure timing in accordance with fluctuations of the speed of surface at the exposure position so that the exposure interval in the sub-scanning direction on the photosensitive drum comes close to a constant interval. | 04-14-2011 |

| 20090097064 | PRINTING APPARATUS, JOB PROCESSING METHOD, PROGRAM, AND STORING MEDIUM - A printing apparatus which enables to efficiently improve the productivity of the printed matter and to efficiently supply the resource. It is determined whether a printing interrupting factor occurs regarding a job for which a printing process is performed. When it is determined that the printing interrupting factor occurs regarding the job, a subsequent job following the job is controlled to be performed in priority to the job. When the job, regarding which, it is determined that the printing interrupting factor occurs, is the job related to image quality adjustment, the subsequent job is restricted to be performed in priority to the job regarding which, it is determined that the printing interrupting factor occurs. | 04-16-2009 |
