Patent number: 9144908Abstract: A manipulator device has an arm portion and a hand portion The hand portion includes one or more finger portions that manipulate a target object. Each finger portion includes a slip sensor and multiple contact sensors, with at least one contact sensor at a position proximate to the slip sensor and at least another contact sensor at a position remote from the slip sensor. When the contact sensors at the positions remote from the slip sensor detect contact of the target object and the contact sensors arranged at the positions proximate to the slip sensors do not detect contact, a position of the finger portion is moved by a distance corresponding to the distance between the contact sensors detecting contact of the target object and the contact sensors arranged at the positions proximate to the slip such that a detecting position of the slip sensor is coincident with a position of the target object.Type: GrantFiled: April 18, 2012Date of Patent: September 29, 2015Assignee: Hitachi, Ltd.Inventors: Makoto Saen, Kiyoto Ito, Yoshimitsu Yanagawa, Tomomi Takahashi

Patent number: 8922407Abstract: A reference A/D conversion unit is connected in parallel to an input common to a time-interleaved A/D converter to be a calibration target, and the output of each unitary A/D conversion unit which makes up the time-interleaved A/D converter is calibrated in a digital region by using a low-speed high-resolution A/D conversion result output from the reference A/D conversion unit. Also, fCLK/N (fCLK represents an overall sampling rate of the time-interleaved A/D converter, and N is relatively prime to the number of unitary A/D conversion units connected in parallel M) is set as the operation clock frequency of the reference A/D conversion unit. Samplings of all unitary A/D conversion units can be sequentially synchronized with the sampling of the reference A/D conversion unit, and the operation clock frequency of the reference A/D converter can be made N times slower than the overall sampling rate of the time-interleaved A/D converter.Type: GrantFiled: April 30, 2014Date of Patent: December 30, 2014Assignee: Hitachi, Ltd.Inventors: Takashi Oshima, Taizo Yamawaki, Tomomi Takahashi

Publication number: 20110267211Abstract: In this invention, the accuracy between an input analog voltage and a digital output signal can be enhanced. A background digital correction type A/D converter includes a reference A/D conversion unit, a main A/D conversion unit, and a digital corrector. The main A/D conversion unit executes an A/D converting operation at a high speed, whereas the reference A/D conversion unit executes an A/D converting operation with high resolution, respectively. Each of main digital output signals of the main A/D conversion unit and a reference digital output signal of the reference A/D conversion unit are supplied to one input terminal of the digital corrector and the other input terminal thereof respectively. The digital corrector outputs a correction-processing digital output signal. The reference A/D conversion unit includes a ?? A/D converter and a Nyquist filter. The Nyquist filter suppresses a high-frequency quantization error of the ?? analog-digital converter.Type: ApplicationFiled: April 27, 2011Publication date: November 3, 2011Inventors: Takashi OSHIMA, Tomomi TAKAHASHI

Patent number: 7843369Abstract: In a wireless transmitter and receiver, a background calibration type analog-to-digital converter generally occupies a large area because of the phase compensating capacity of an op-amp included in a reference analog-to-digital conversion unit. Further, the calibration type analog-to-digital converter generally requires a sample and hold circuit to exclude influence of parasitic capacitance of wirings, thereby increasing power consumption. Digital calibration is performed by using, as a signal for calibration, an input signal of a digital-to-analog converter in a transmitter circuit of the wireless transmitter and receiver and inputting an output signal from the digital-to-analog converter to the analog-to-digital converter in the receiver circuit.Type: GrantFiled: November 13, 2008Date of Patent: November 30, 2010Assignee: Hitachi, Ltd.Inventors: Tomomi Takahashi, Takashi Oshima, Taizo Yamawaki
