  • Patent number: 10593820
    Abstract: In the solar cell module, a first solar cell and a second solar cell are stacked together with an electroconductive member interposed therebetween, such that a cleaved surface-side periphery on a light-receiving surface of the first solar cell overlaps a periphery on a back surface of the second solar cell. The first solar cell and the second solar cell each have: photoelectric conversion section including a crystalline silicon substrate; collecting electrode; and back electrode. At a section where the first solar cell and the second solar cell are stacked, the collecting electrode of the first solar cell and the back electrode of the second solar cell are electrically connected to each other by coming into contact with the electroconductive member. An insulating member is provided on a part of the cleaved surface-side periphery on the light-receiving surface of the first solar cell, where the collecting electrode is not provided.

  • Patent number: 10365628
    Abstract: A positioning control device of an actuator provided with a strain wave gearing has a full-closed control system for feeding back a position of a load shaft, and driving and controlling a motor so as to position the load shaft at a target position. The full-closed control system has an H? compensator designed so that, when a generalized plant having angular transmission error in the strain wave gearing as a disturbance input is assumed, an H? norm of a transfer function from the disturbance input of the generalized plant to an evaluation output is a predetermined value or less. Mechanical vibration during positioning response caused by angular transmission error in the strain wave gearing can be reliably suppressed.

  • Patent number: 10254740
    Abstract: A positioning control system is provided with a state-feedback control system with a state observer as a full-closed control system for driving and controlling a motor so that a load shaft, which is an output shaft of a strain wave gearing, is positioned at a target position on the basis of a load shaft position actually detected. The state observer estimates a motor shaft position and a motor velocity based on a control input for the motor and the load shaft position. The state-feedback control system feeds back the state quantity of the object of control using the load shaft position as well as estimated motor shaft position and estimated motor velocity obtained by the state observer. It is possible to suppress resonant vibration caused by angular transmission error in the strain wave gearing and perform highly accurate positioning.
