Patent number: 11056597Abstract: A photoelectric conversion device includes a photoelectric conversion element formed of a polar material and including no p-n junction, and first and second electrodes provided on the photoelectric conversion element and arranged at an interval. Space-inversion symmetry of a structure of the photoelectric conversion element is broken. The first and second electrodes are each formed of a metal material that generates no substantial potential barrier preventing majority carriers for the photoelectric conversion element from moving from the electrode to the photoelectric conversion element. Light incidence on the photoelectric conversion element without voltage application between the first and second electrodes causes electromotive force to be generated between first and second electrodes, and enables electric current to be continuously taken out from the first and second electrodes.Type: GrantFiled: December 27, 2018Date of Patent: July 6, 2021Assignee: RIKENInventors: Masao Nakamura, Masashi Kawasaki, Yoshinori Tokura, Naoto Nagaosa, Takahiro Morimoto, Yoshio Kaneko

Patent number: 8950738Abstract: To provide a vibration-damping support device that requires a smaller space for its own installation. A vibration-damping support device is provided with a rubber mount, a support member supporting the rubber mount thereon, and stoppers. The rubber mount is to be attached to a mounting platform for an object which is installed in a hydraulic excavator and is to be damped, for example, an engine that vibrates in vertical and horizontal directions, and has an elastic member of a rubber or like member for absorbing vibrations of the engine. The support member can be, for example, a support bracket to be fixedly secured on an unillustrated revolving frame. The stoppers are arranged integrally with the support bracket, and prevent an excessive deformation of the elastic member of the rubber mount under vibrations of the engine. The stopper is arranged on an upper side of the support bracket, while the stopper is arranged on a lower side of the support bracket.Type: GrantFiled: February 20, 2009Date of Patent: February 10, 2015Assignee: Hitachi Construction Machinery Co., Ltd.Inventor: Masao Nakamura
