Patent number: 5642124Abstract: An image processing system in which a process for implementing part of the display management function is provided separately from the window system or the operating system. In consequence, changes in the system configuration can be coped with only by conducting addition on a user program or the process which implements part of the display management function without modifying or altering the window system or the operating system. This eliminates modification or alteration of the window system or the operating program and increases the portability of the program.Type: GrantFiled: September 30, 1994Date of Patent: June 24, 1997Assignee: Canon Kabushiki KaishaInventors: Tomoaki Kawai, Hiroaki Satoh, Hideyuki Tamura

Patent number: 4939971Abstract: A tremolo device for a guitar includes an upper plate pivotably mounted about a first fulcrum on a guitar body, at least one spring urging the upper plate in one rotating direction, a part of the guitar body coming into contact with the upper plate to limit the rotation thereof in the one rotating direction, to bring the upper plate to a predetermined position, and a lower plate pivotably mounted about a second fulcrum and pulled in another direction opposite to the one direction by the tension of strings of the guitar. The rotation of the lower plate is limited by the upper plate in the predetermined position when the tremolo device is inactivated, and when the tremolo device is activated in such a manner that the lower plate is rotated in the other direction, the upper and lower plates are rotated together, but when the tremolo device is activated in such a manner that the lower plate is rotated inthe one direction, only the lower plate is rotated.Type: GrantFiled: September 30, 1988Date of Patent: July 10, 1990Inventor: Hiroaki Satoh
