Patent number: 8001294Abstract: The present invention provides methods and apparatus for transferring and storing data among processors and memory in a multiprocessor system. The data is compressed locally before it is sent to a shared memory. The memory stores the data in its compressed state, but the data is aligned in the memory in the same manner as uncompressed data would be. A tag table keeps track of the compression type and compressed data size for a set of data at a given address block. A data compressor and a data expander may be implemented in a direct memory access controller accessible to multiple coprocessors, or the compressor and the expander may be implemented within the coprocessors.Type: GrantFiled: September 27, 2005Date of Patent: August 16, 2011Assignee: Sony Computer Entertainment Inc.Inventors: Keisuke Inoue, Eiji Iwata

Publication number: 20110170891Abstract: A pressure lever journaling a pressure roller is rockably connected to a fixation frame journaling a fixing roller. A pivotal position of the pressure lever is adjusted by a motor through driving gears, sector gears, press-contact adjusting levers, and press contact springs, so that a mode of a fixing press contact force is set to a heavy press contact mode or a light press contact mode. By a control section, at start-up immediately after power-on and on basis of a temperature and a humidity detected by a temperature and humidity sensor, the heavy press contact mode is established for rectifying poor curl conditions of paper sheets on condition that the present temperature and humidity environment is a high-temperature high-humidity environment or the light press contact mode is established for rectifying poor fixation performance on condition that the present temperature and humidity environment is a low-temperature low-humidity environment.Type: ApplicationFiled: August 19, 2009Publication date: July 14, 2011Applicant: Konica Minolta Business Technologies, Inc.Inventor: Keisuke Inoue

Publication number: 20100239280Abstract: Electric charge remaining on a photoreceptor after transfer causes image deterioration. According to one conventional method widely used in view of this problem, erase light is emitted onto a photoreceptor after the transfer to remove the electric charge remaining on the photoreceptor. However, such a method poses the following problem: emission of erase light leads to light-induced fatigue of the photoreceptor, and as a result, the photoreceptor which has deteriorated from the light-induced fatigue wears down due to abrasion and the like with a cleaner blade, resulting in a shorter lifetime of the photoreceptor. Thus, the thickness of the photosensitive layer is detected to acquire the amount of thickness decrease, and the amount of the erase light is reduced according to the acquired amount of thickness decrease.Type: ApplicationFiled: March 17, 2010Publication date: September 23, 2010Applicant: Konica Minolta Business Technologies, Inc.Inventor: Keisuke INOUE
