Patents by Inventor Hiromitsu Ueda

Hiromitsu Ueda has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Organic semiconductor device, organic el device, photodiode sensor, display device, light-emitting apparatus, electronic device, and lighting device
    Patent number: 12232342
    Abstract: An organic semiconductor device with low driving voltage is provided. The organic semiconductor device includes a layer containing an organic compound between a pair of electrodes. The layer containing an organic compound includes a hole-transport region. The hole-transport region includes a first layer and a second layer. The first layer is positioned between the anode and the second layer. When a potential gradient of a surface potential of an evaporated film is set as GSP (mV/nm), a value obtained by subtracting GSP of an organic compound in the second layer from GSP of an organic compound in the first layer is less than or equal to 20 (mV/nm).

  • Opener cap
    Patent number: 9227771
    Abstract: The purpose of the invention is to provide a very safe opener cap that can easily open a film serving as a section to be opened without scattering the contents. A can body (10) and a screw cap (20) are screwed together, and the screw cap (20) and an opener (30) are ratcheted together so as to rotate as a unit in the direction of the screw cap (20) tightening. Blade angles of an annular blade (34) are configured so that the blade angle in the direction of the screw cap (20) loosing is gentler than the blade angle in the direction of tightening.

  • Electric motor car control system
    Patent number: 8648554
    Abstract: An embodiment of an electric motor car control system includes a resistor connected parallel to a main motor cut-off switch, or a switch for grounding terminals of the main motor, to discharge electric charges accumulated in stray capacitances of the main motor, whereby the electric motor car control system can prevent electrical shocks due to electric charges accumulated in main motor stray capacitances.
