Patent number: 8913906Abstract: An image forming apparatus includes an image bearing member for bearing a toner image, a rotatable endless belt, a first driving member for rotationally driving the endless belt and in contact with an inner peripheral surface of the endless belt, and a second driving member for rotationally driving the endless belt and in contact with an outer peripheral surface of the endless belt. In addition, a tension detecting unit detects a state of tension of the endless belt and a controller controls a rotational speed of the second driving member. A driving force applied from the second driving member to the endless belt is smaller than a driving force applied from the first driving member to the endless belt, and the tension detecting unit includes a metal roller contacting the inner peripheral surface of the endless belt and detects the tension by movement of the metal roller which follows the endless belt.Type: GrantFiled: July 5, 2012Date of Patent: December 16, 2014Assignee: Canon Kabushiki KaishaInventors: Akimichi Suzuki, Takao Nada, Shinya Kawakami

Patent number: 7893536Abstract: A multilayer interconnect configuration is formed on a semiconductor substrate where a semiconductor integrated circuit is provided. Each layer of the multilayer interconnect configuration has a plurality of pads. Except for the pads of the top layer, the area of the pads is reduced relative to the pads of the top layer. The pad area is reduced by forming a plurality of openings in the pads, or by forming a plurality of notches in the pads whereby the pads have a comb configuration. The capacitance can be significantly reduced by decreasing the area. The reduction of capacitance allows for significantly reducing the effect of a low-pass filter produced from the interconnect metal resistance and the pad capacitance, which slows down the circuit operation. Therefore the high-speed operation can avoid degradation.Type: GrantFiled: May 8, 2006Date of Patent: February 22, 2011Assignee: Kabushiki Kaisha ToshibaInventors: Shuichi Takada, Shinya Kawakami

Patent number: 7839183Abstract: A circuit for discriminating a ‘Noisy’ state of an output of a squelch circuit is disclosed. A circuit for resolve the ‘Noisy’ state of the output of the squelch circuit is also disclosed which uses the output identification circuit. The output of the squelch circuit and a clear signal are input into a first AND gate. The output of the first AND gate is input into a first flip-flop. An inversed signal of the output of the first AND gate is input into a second flip-flop. The outputs of the first and second flip-flops are input into a discriminating unit including a second AND gate. The ‘Noisy’ state is identified by the output of the second AND gate. Based on the identification result, sensitivity of the squelch circuit is regulated.Type: GrantFiled: September 13, 2007Date of Patent: November 23, 2010Assignee: Kabushiki Kaisha ToshibaInventor: Shinya Kawakami
