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: 8350595Abstract: There is a need to ensure operation performance of a circuit region under DVFS control at low costs and highly precisely while a power-supply voltage change is made to the region. A first circuit (FVA) uses a first power-supply voltage (VDDA) for operation. A second circuit (NFVA) uses a second power-supply voltage (VDDB) for operation. A clock delay may be adjusted between paths for transmitting a clock to these circuits. When VDDA equals VDDB, a clock is distributed to FVA through a path that does not contain a delay device for phase adjustment. When the power-supply voltage for the FVA region is reduced, a clock is distributed to the FVA region based on a phase equivalent to one or two cycles of the clock displaced. Synchronization control is provided to synchronize clocks (CKAF and CKBF) and ensures operation so that a phase of two clocks to be compared fits in a range of design values while the power-supply voltage for the first circuit is changed.Type: GrantFiled: April 3, 2012Date of Patent: January 8, 2013Assignee: Renesas Electronics CorporationInventors: Yusuke Kanno, Makoto Saen, Shigenobu Komatsu, Masafumi Onouchi
