Publication number: 20140009187Abstract: An integrated circuit includes an outputting unit in which a CMOS inverter configured from a first MOS transistor and a second MOS transistor for outputting a second signal using a first signal as an input thereto and a third MOS transistor that includes a gate terminal to which a control signal for controlling the outputting of the second signal is inputted and that is in an off state when the control signal indicates inhibition of the outputting of the second signal are cascade-connected to each other, and a fixing unit that fixes a value of the first signal based on the control signal. When the control signal indicates inhibition of the outputting of the second signal, the fixing unit fixes the value of the first signal to a value with which the first or second MOS transistor is placed in an off state.Type: ApplicationFiled: September 6, 2013Publication date: January 9, 2014Applicant: Fujitsu LimitedInventors: Masao IDE, Tomohiro TANAKA

Patent number: 6598255Abstract: A cleaning rotary brush 1 comprises a hard base 3 mounted to a rotary shaft and a plurality of ridged projections 27 formed on and projecting from the working surface of the base 3, the tops of said ridged projections 27 in contact with an object to be cleaned while rotating in substantially the same plane. The ridged projections 27 are made of a polyvinyl acetal porous elastomer and disposed continually on a plurality of phantom setting lines 31 extending from inner reference, points 31a on the side of the center of rotation 35 of the working surface to outer reference points 31b on the side of the outer periphery 17b of the working surface. The length L1 in a longitudinal direction of said ridged projections 27 is made longer than the length D1 in a widthwise direction of the ridged projections 27.Type: GrantFiled: January 16, 2001Date of Patent: July 29, 2003Assignee: Aion Co., Ltd.Inventors: Shuki Gohda, Masao Ide, Konomu Tokunaga

Patent number: 6527706Abstract: In an endoscopic insertion instrument having a rigid tip end section, an elongated flexible body, and an angle section connected between the rigid tip end section and the flexible body, a joint construction connects an angle section to the fore end of the flexible body. A couple of connecting rings are provided opposingly at joining ends of the angle section and the flexible body. At least one aperture is provided in an outer one of the connecting rings to feed a flux. At least one angle section operating is passed through the connecting ring. The operating wire is encased in a sheathing coil, the fore end of which is fixed to the inner one connecting rings. To prevent flux from getting into the closed sheathing coil, a shield portion is formed around an outer periphery of the sheating coil over a predetremined range in axial length.Type: GrantFiled: February 2, 2001Date of Patent: March 4, 2003Assignee: Fuji Photo Optical Co., Ltd.Inventor: Masao Ide
