  • Patent number: 10389215
    Abstract: A motor including a rotor, and a stator having a plurality of coils wound around slots, wherein at least any one of the coils includes a single aluminum wire, a single copper wire joined to the aluminum wire, a stranded wire (lead wire) joined to the copper wire, a cold-pressure-welded joint portion (joint portion) joined between the aluminum wire and the copper wire by cold pressure welding, and a non-pressure welded joint portion (joint portion) provided between the copper wire and the stranded wire (lead wire). A burr covered by an insulation member (insulation tube) is provided in the cold-pressure-welded joint portion (joint portion). A thickness of the insulation member (insulation tube) is larger than a height of the burr.

  • Patent number: 10311770
    Abstract: Provided is a display system for a vehicle. The display system includes a display device installed to be visually recognizable from the outside of a vehicle, and a control device configured to cause the display device to display state information of the vehicle. The control device receives a signal from a sensor that senses a distance from the vehicle to an object around the vehicle, and the control device changes display of the display device based on the distance.

  • Patent number: 8203625
    Abstract: An image capture device according to the present invention includes: an optical system for producing a subject's image; an imager with multiple photodiodes, which reads an electrical signal representing the intensity of light that has been incident on each photodiode from the photodiode, thereby generating an image signal representing the subject's image; a controller, which acquires sensitivity information by photometry in order to adjust the sensitivity of the imager to light and which selects one of multiple methods for reading the electrical signal from each photodiode according to the sensitivity information acquired; and a driver for driving the imager by the reading method selected. The multiple reading methods include a mixing reading method, by which the electrical signals supplied from the photodiodes are added together and then output.

  • Publication number: 20110115971
    Abstract: The present invention provides an image capture device that can omit calculating a pulse signal that should otherwise be used to get a flash fired during a flash-ON sequential shooting operation. An image capture device includes: an image capturing section configured to capture a subject's image; a flashing section configured to store electricity and emitting flash light using the electricity; a power supply configured to supply the electricity; and a control section configured to control the supply of the electricity to the flashing section. If the flashing section performs preliminary flashing and main flashing sequentially, the control section supplies no electricity to the flashing section after the preliminary flashing is done and before the main flashing is performed for a first time.

  • Publication number: 20090174792
    Abstract: An inter-line CCD (IT-CCD) capable of reading signals in two read modes, a field read mode and a frame read mode, is used to control, by a system control means, a CCD exposure and a signal read mode, a short-time exposure signal (Short signal) acquires an image by a field read and a long-time exposure signal (Long signal) acquires an image by a frame read, and these two images are synthesized by a signal synthesizing means to expand a dynamic range.
