Patent number: 8020486Abstract: The objective of the present invention is to provide a device that accurately communicates a subtle variation of an operation side to an action side. Specifically, in the present invention, an operating device is provided to perform a lock release operation of an extension device. The operating device feeds oil to a valve chamber by pressing a piston. When the flow rate of the fed oil is excessive, the valve is pressed to an opening resisting a biasing force of a compressed spring, thereby a rapid increase in the oil supplied to the action section is suppressed. Further, the supplied oil is suppressed to a very small amount by the throttle section, thereby an increase in the operation amount on the action section side is suppressed while maintaining the supply of the oil.Type: GrantFiled: May 22, 2008Date of Patent: September 20, 2011Assignee: Fumoto Giken Co., Ltd.Inventors: Naoyuki Yamamoto, Ryouhei Yamamoto

Patent number: 7773898Abstract: This invention provides an image forming apparatus capable of outputting, without using any special device, an image which is free from changes in density and tint even upon crisscross rotation and exhibits good proportion of a small character. To accomplish this, the pulse width of a laser emission signal is controlled at 16 levels for one dot at 600 dpi, controlling an actual image in the main scanning direction. When adjusting vertical and horizontal line widths, patch data are created by rotating an anisotropic pattern through 0° and 90° (S1 in FIG. 5). Then, a reader/scanner (15) reads each patch as density data (S2 in FIG. 5). A pulse width, that is, line width correction value at which the densities of the patch patterns rotated through 0° and 90° become equal to each other is obtained (S3 in FIG. 5).Type: GrantFiled: December 5, 2007Date of Patent: August 10, 2010Assignee: Canon Kabushiki KaishaInventors: Takahiro Nakase, Naoyuki Yamamoto, Masanobu Nakajima
